Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The organic light emitting diode (Organic Light Emitting Diode, OLED) display panel is gradually increasing its market share due to its advantages of high sensitivity, high contrast ratio, wide viewing angle, low power consumption, and thin volume.

When the OLED display panel is used as the display panel of the hidden camera solution, in order to achieve a high transmittance in the high transmittance display area on the OLED display panel, the high transmittance display area needs to use a non-high transmittance display area. Different film materials and driving methods in the display area. For example, the anode and cathode materials used in the high transmittance display area are transparent conductive film materials, and the non-high transmittance display area uses metal materials. The transmittance of the transparent conductive film material is higher than that of the metal material; the high transmittance display area uses metal materials. The passive driving method is adopted, and the non-high transmittance display area adopts the active driving method. Compared with the active driving method, the passive driving method does not need to set thin film transistors, so the transmittance is high.

Due to the difference in film material and driving method (film structure) between the high transmittance display area and the non-high transmittance display area, the service life of the high transmittance display area is lower than that of the non-high transmittance display area. When reaching the same use time, due to the large loss of the high transmittance display area, its energy consumption is also greater than that of the non-high transmittance display area, that is, the power consumption of the high transmittance display area is higher than that of the non-high transmittance display area. rate display area. Then, if the same electrical signal is used to drive the high transmittance display area and the non-high transmittance display area, the actual display brightness is different, and the brightness of the high transmittance display area is lower than that of the non-high transmittance display area. area, resulting in uneven display between the high transmittance display area and the non-high transmittance display area.

It is worth noting that the aforementioned high transmittance display area can be used to hide other optical components such as light sensors in addition to hiding the front camera.

FIG. 1 is a schematic structural diagram of a display panel according to an exemplary embodiment. Referring to FIG. 1 , the display panel 100 includes a first display area 101 and a second display area 102 , the second display area 102 surrounds the first display area 101 , and the first display area 101 is close to one side of the second display area 102 side settings. The transmittance of the first display area 101 is higher than that of the second display area 102 , that is, the first display area 101 is the aforementioned high transmittance display area, and the second display area 102 is the aforementioned non-high transmittance display area.

Here, FIG. 1 is only an example of a display panel. In other implementations, the shape, position and size of the first display area 101 may adopt different implementations. For example, the first display area 101 is circular, or the first The display area 101 is located in the middle or the like of the display panel.

FIG. 2 is a schematic diagram of the application of the display panel in FIG. 1. Referring to FIG. 2, the display panel 100 is applied in a terminal device 10 (such as a mobile terminal). In the terminal device 10, the position corresponding to the first display area 101 can be set before Optical components 20 such as cameras or light sensors are installed.

FIG. 3 is a hierarchical structure diagram of the display panel 100 . Referring to FIG. 3 , the display panel 100 includes a substrate 110 , an array structure 120 on the substrate 110 (eg, a glass substrate), an organic light-emitting material layer 130 and a cathode layer 140 in sequence. Wherein, the difference in service life of the first display area 101 and the second display area 102 may be caused by at least one factor among the film layer material and the film layer structure. For example, the array structure 120 and the cathode layer 140 of the first display area 101 are made of high transmittance materials, while the array structure 120 and the cathode layer 140 of the second display area 102 are made of general transmittance materials. The service life of the transmittance material is lower than that of the general transmittance material. For another example, the array structure 120 of the second display area 102 includes a thin film transistor array and an anode connected to the thin film transistor array, that is, the second display area 102 adopts an active driving mode, and the array structure 120 of the first display area 101 Only the anode array is included, that is, the first display area adopts the passive driving mode. Due to the difference in the film structure of the two, the service life of the passive driving mode is lower than that of the active driving mode.

It should be noted that, one high transmittance display area may be set on the display panel, or two or more high transmittance display areas may be set.

Of course, the structure in FIG. 3 is only an example, the entire panel may be a passively driven OLED display panel, or the entire panel may be an actively driven OLED display panel, as long as there are the above-mentioned first display area 101 and second display area 102 The solutions provided by the present disclosure may be employed.

In the display panel shown in FIG. 1 , the first refresh rate of the first display area 101 is greater than the second refresh rate of the second display area 102 .

In the embodiment of the present disclosure, the display panel has two display areas, and the transmittances of the two display areas are different. Correspondingly, the refresh rates used in the realization of the two display areas are also different. The refresh rate used in the display area with high refresh rate is also high, and the driving circuit will rewrite the pixel voltage to the pixels in the display area every time the refresh rate is refreshed. In this way, the pixels in the display area with high refresh rate can be charged more frequently. , thereby making up for the loss of brightness caused by the high energy consumption of the high transmittance display area, reducing the display difference between the two display areas, and improving the uniformity of the display panel.

It is worth noting that, since the energy consumption of the high transmittance display area in the present disclosure is related to the usage time, the display mode in the present disclosure in which the first refresh rate of the first display area 101 is greater than the second refresh rate of the second display area 102 , it can be maintained during the use of the display panel; it can also be turned on after the display panel reaches a certain use time.

FIG. 4 shows a schematic structural diagram of a data line of a display panel provided by an embodiment of the present disclosure. Referring to FIG. 4 , the signal lines 121 of the first display area 101 and the signal lines 121 of the second display area 102 are insulated from each other.

Here, the signal line 121 refers to the gate line 122 and the data line 123 connected to the thin film transistor in the array structure, the gate line 122 is connected to the gate of the thin film transistor, the data line 123 is connected to the source of the thin film transistor, and the drain of the thin film transistor pole and anode connection. The gate line 122 is used for providing the gate driving signal output by the gate driving circuit to the gate of the thin film transistor, thereby controlling the switching of the thin film transistor; the data line 123 is used for providing the data signal output by the source driving circuit to the gate of the thin film transistor. source, so as to control the brightness of the sub-pixels corresponding to the thin film transistors.

In this implementation manner, the signal lines of the two display areas are set in isolation, which facilitates the use of different refresh rates for display control of the two display areas.

In the embodiments of the present disclosure, the thin film transistor may be either a PMOS transistor or an NMOS transistor.

As shown in FIG. 4 , in order to isolate the signal line 121 of the first display area 101 from the signal line 121 of the second display area 102 , the original gate line 122 or data line 123 will be separated when passing through the first display area 101 . It can be broken into multiple sections, so as to realize the insulation of the signal lines of the two display areas.

For the disconnected signal line, the parts of the signal line belonging to the two display areas are connected to the driving circuit through different leads, which are arranged with the signal line at the interlayer and connected through the vias between the layers. This makes wiring easier.

For example, if a signal line is broken into 3 sections, and the two ends belong to the second display area, the two sections can be connected by wires and then connected to the driving circuit. When the wires are arranged, the first display area can be bypassed to avoid affecting the first display area. transmittance.

In an implementation manner of the embodiment of the present disclosure, the number of rows and columns of pixels included in the first display area 101 are both less than six.

In this implementation, there are usually fewer pixels in the display area with high transmittance, for example, the number of rows and columns included is less than 6. This design is generally used to design off-screen cameras, off-screen fingerprints, etc., so that Realize full screen design.

FIG. 5 is a schematic diagram of wiring of a first display area according to an embodiment of the present disclosure. Referring to FIG. 5 , when the number of pixels included in the first display area 101 is small, the first display area adopts at least one of the following settings: all data lines 123 are connected together; all gate lines 122 are connected together.

In this implementation manner, since the number of pixels in the first display area is small, the data lines of this part of the pixels are connected together or the gate lines of this part of the pixels are connected together to simplify the pixel control of the display panel.

In this implementation, since the data lines in the first display area are connected together, and each data line is connected to a column of sub-pixels, in this case, a row of sub-pixels in the first display area is controlled at the same time, This row of sub-pixels displays the same brightness; or, the grid lines in the first display area are connected together, and each grid line is connected to a row of sub-pixels, in this case, a column of sub-pixels in the first display area is simultaneously controlled, this column of sub-pixels displays the same brightness; or, the gate lines in the first display area are connected together, and the data lines are connected together, in this case, all the sub-pixels in the first display area are controlled at the same time, and the sub-pixels in the first display area display the same brightness.

In the above-mentioned situations, several pixels display the same color and brightness, and the color and brightness displayed by these pixels can take the average value of the colors and brightness that the two pixels originally need to display.

FIG. 6 is a timing diagram in the related art, and FIG. 7 is a timing diagram of pixels in the first display area when the structure in FIG. 5 of the present disclosure is adopted. It can be seen that, after the structure shown in Figure 5, the writing frequency of the gate conduction level (low level) of the gate line (gate) becomes higher, and accordingly, the frequency of writing the data voltage of the data line (source) also changes. high.

In another implementation manner of the embodiment of the present disclosure, the number of pixels in the first display area 101 is relatively large, for example, the number of rows and columns included are both greater than or equal to 6,

When the number of pixels included in the first display area 101 is large, each data line and each gate line in the first display area 101 are insulated from each other.

In this implementation, if the number of sub-pixels in the first display area is large, the data lines and gate lines are insulated and each sub-pixel is independently controlled to ensure the display accuracy of the first display area 101 .

In an implementation manner of the embodiment of the present disclosure, the first refresh rate may be an integer multiple of the second refresh rate.

In this implementation, the refresh rate of an integral multiple of the low transmittance display area is used as the refresh rate of the high transmittance display area, which can ensure that the first display area and the second display area can always maintain the same picture, and at the same time Display uniformity is guaranteed by adjusting the refresh rate.

For example, the first refresh rate is twice the second refresh rate. On the one hand, the control sequence is simple, and on the other hand, the refresh rate can be increased, and the purpose of display uniformity can be achieved.

In another implementation manner of the embodiment of the present disclosure, the first refresh rate may also be a non-integer multiple of the second refresh rate.

FIG. 8 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. Referring to FIG. 8 , the display device includes a display panel 100 .

Optionally, the display device further includes: a driving unit 200 configured to obtain a driving signal; and using the driving signal to control the sub-pixels in the first display area and the second display area to operate according to the first refresh rate and the second refresh rate, respectively.

Exemplarily, the driving unit 200 is generally a driving integrated circuit (Integrated Circuit, IC). The driver IC includes a gate driver circuit and a source driver circuit. The gate driver circuit is used to write a gate driver signal to the gate line to control the switching of the thin film transistor; the source driver circuit is used to write a data signal to the data line, This controls the color and brightness of individual pixels.

Optionally, the driving unit 200 is configured to acquire image frames to be displayed, and the number of image frames to be displayed per unit time is equal to the second refresh rate;

When the sub-pixels in the first display area display an image frame, determining the pixel voltage based on the pixel grayscale value corresponding to the first display area in the image frame;

When the sub-pixels in the first display area display the supplementary frame, the pixel voltage is determined based on the pixel grayscale values corresponding to the first display area in several image frames adjacent to the supplementary frame; the supplementary frame refers to the ratio of the first display area to the Frames displayed in the second display area.

The unit time here can be one second. The image frame refers to the image transmitted from the terminal device to the display panel to be displayed on the display panel, and the image is displayed on the first display area and the second display area at the same time. Since the refresh rate of the first display area is greater than the refresh rate of the second display area, the first display area can display additional frames in addition to images of image frames, and these frames are used to display supplementary frames. The content of the supplementary frame is determined according to the content of several adjacent image frames.

In this implementation manner, since the refresh rate of the first display area is greater than the refresh rate of the second display area, but the image frame acquired by the display device is the same as the refresh rate of the second display area, the first display area is In other words, in addition to displaying image frames, supplementary frames need to be displayed to ensure a high refresh rate. Here, the supplementary frame is determined by the image frames before and after it, so as to ensure the continuity of the image display.

Here, the supplementary frames can be evenly interleaved between multiple image frames. For example, if there are 60 image frames and 10 supplementary frames, then a supplementary frame is set after every 6 image frames. For another example, there are 60 image frames and 60 supplementary frames, set a supplementary frame after each image frame.

In this implementation manner, several image frames adjacent to the supplementary frame refer to a total of several image frames adjacent to the supplementary frame before, after, or before and after the supplementary frame.

Optionally, when the first refresh rate is an integer multiple of the second refresh rate, each image frame is provided with at least one supplementary frame, and each image frame and at least one supplementary frame following the image frame display the same image. The supplementary frame is displayed immediately after the image frame.

In this implementation manner, when the first refresh rate is an integer multiple of the second refresh rate, the image frame only needs to be repeatedly displayed as a supplementary frame, and the processing is simple.

Optionally, the driving unit 200 is configured so that the pixel voltage of the first grayscale of the first color provided to the first display area is smaller than the first grayscale of the first color provided to the second display area , the first color is any color, and the first grayscale is any grayscale.

For example, if the first display area and the second display area display a red gray scale of 5 at the same time, the pixel voltage provided by the driving unit 200 to the first display area is lower than that of the second display area.

In this implementation, when the first refresh rate is an integer multiple of the second refresh rate, if the first display area and the second display area use the same pixel voltage, the final display brightness of the first display area will be higher than that of the second display area. The same grayscale brightness of the display area. To avoid this, the pixel voltage supplied to the pixels in the first display area is controlled to be smaller than the pixel voltage supplied to the pixels in the second display area. Since several identical frames in the first display area correspond to one frame in the second display area, the sum of the luminances of several identical frames in the first display area is equal to the luminance of one frame in the second display area, ensuring display uniformity .

Optionally, when the first refresh rate is a non-integer multiple of the second refresh rate, at least one supplementary frame is set after at least two consecutive image frames, and each supplementary frame corresponds to each subpixel in the first display area. The brightness is the average value of the brightness of each sub-pixel in the first display area corresponding to at least one adjacent image frame of the supplementary frame.

In this implementation manner, the average value of several images before and after is used as the supplementary frame, so as to ensure the continuity of image display, and at the same time, it can ensure the simplicity of processing.

Optionally, when the sub-pixels in the first display area display the same gray scale using the first refresh rate and the sub-pixels in the second display area display the same gray scale using the second refresh rate, the sub-pixels in the first display area and the sub-pixels in the second display area display the same gray scale. The luminance difference of the pixels is less than the threshold.

In this implementation manner, the first refresh rate and the second refresh rate used in the present disclosure can be selected according to the brightness of the same grayscale display in the two display areas, so as to ensure that the difference between the pixels displaying the same grayscale is within the threshold range, thereby ensuring that Uniformity of display.

Optionally, the threshold is less than or equal to 5%.

In this implementation, the selected threshold value is equal to or less than 5%, so that uniformity can be guaranteed to the greatest extent.

Fig. 9 is a flow chart of a display control method according to an exemplary embodiment. Referring to FIG. 9, the method may be performed by the aforementioned driving unit, and the display control method may include:

In step S11, a drive signal is acquired.

Here, the driving signal is generated based on the first refresh rate and the second refresh rate. The first refresh rate and the second refresh rate can be determined in advance before leaving the factory, and only need to be obtained from the local area for use during work. The determination method is to control the second display area to display a monochrome image by using the second refresh rate, and control the first display area to display the same monochrome image of the same gray scale by using different refresh rates in turn.

When the number of sub-pixels in the first display area is small, you can add one each time on the basis of the second refresh rate; and when the number of sub-pixels in the first display area is large, you can add one on the basis of the second refresh rate Double the value of the second refresh rate each time.

When the luminance difference between the sub-pixels of the first display area and the sub-pixels of the second display area is less than the threshold, the refresh rate of the second display area is selected as the first refresh rate.

For example, the rows and columns of sub-pixels in the first display area are both less than 6, and the second refresh rate is 60Hz. At this time, you can start from 61Hz, add 1 each time, and display at different refresh rates in turn, and select the one whose brightness difference is less than the threshold. as the first refresh rate.

For example, the rows and columns of sub-pixels in the first display area are both greater than 6, and the second refresh rate is 60Hz. At this time, you can start from 120Hz, add 60 each time, and display at different refresh rates in turn, and select the one whose brightness difference is less than the threshold. as the first refresh rate.

When the number of sub-pixels in the first display area is large, the selected first refresh rate can be twice the second refresh rate. On the one hand, the double refresh rate can make up for the problem of excessive energy consumption in the first display area. On the other hand, it is easiest to use 2x refresh rate control.

Optionally, acquiring the driving signal, including:

obtaining image frames to be displayed, and the number of image frames to be displayed per unit time is equal to the second refresh rate;

When the sub-pixels in the first display area display an image frame, determining the pixel voltage based on the pixel grayscale value corresponding to the first display area in the image frame;

When the sub-pixels in the first display area display the supplementary frame, the pixel voltage is determined based on the pixel grayscale values corresponding to the first display area in several image frames adjacent to the supplementary frame; the supplementary frame refers to the ratio of the first display area to the Frames displayed in the second display area.

In step S12, a driving signal is used to control the sub-pixels in the first display area and the second display area to operate according to the first refresh rate and the second refresh rate, respectively.

Optionally, during the time that the second display area displays one frame of picture, the picture displayed in the first display area is the same.

In this implementation, although the refresh rate of the first display area is increased, the displayed images are still the same, ensuring that the contents displayed in the first display area and the second display area at any time belong to the same image, ensuring that the entire display panel Completeness of display.

The corresponding pixel grayscale value determines the pixel voltage; the supplementary frame refers to the frame displayed in the first display area more than the second display area.
