FIG. 1 is a schematic view showing the use of a conventional transparent double-sided display. Referring to FIG. 1, the transparent double-sided display 100 has the capability of being transparent, so that the front and rear of the screen can be penetrated, and the image screen can also be viewed by the user before and after the screen. However, when the user views from the back of the transparent double-sided display 100, the opposite result will be seen, which will disadvantage the subsequent use of the user. Therefore, it is necessary to reverse the image displayed on the back of the transparent double-sided display 100 to facilitate viewing by the user.

2 is a schematic diagram of a display device according to an embodiment of the invention. Referring to FIG. 2 , the display device 200 includes a display unit 202 and an image processing unit 204 . The display unit 202 is coupled to the image processing unit 204 . The display unit 202 has a first display surface and a second display surface opposite to each other. In this embodiment, the display unit 202 is a transparent double-sided display, so that the image displayed on the side of the first display surface by the user and the image displayed on the side of the second display surface by the user in contrast. As shown in FIG. 3A and FIG. 3B, FIG. 3A is assumed to be an image screen on the first display surface, and FIG. 3B is an image screen on the second display surface. Since the display unit 202 is a transparent double-sided display, FIG. 3B Each of the image objects I1 to I5 is opposite to the left and right of the image on the first display surface.

The image processing unit 204 adjusts the image data outputted to the display unit 202 by using the direction state to control the display unit 202 to adjust the image screen displayed on the first display surface and the second display surface. The use direction state means the position of the user relative to the display device 200 or the placement state of the display device 200 itself. For example, if the first display surface is the front surface of the display device 200, the display device 200 may face up or down. The image state is set to adjust the image data output to the display unit 202. The image processing unit 204 controls the display unit 202 to adjust the image frame to adjust the entire image frame, or to adjust only the partial image content of the image frame. For example, performing image left and right inversion on the image screen, image upside down, partial image left and right inversion, partial image upside down, changing image layer display priority order, removing part of image layer, inserting image information, and inserting text information. Or the action of a combination thereof.

For example, FIG. 3C to FIG. 3J are schematic diagrams showing an image of a second display surface according to an embodiment of the present invention. In FIG. 3C, the image processing unit 204 controls the display unit 202 to perform an image left-right inversion operation on the image screen. Therefore, each of the image objects I1 to I5 in the image screen of FIG. 3C is the same as the image image on the first display surface. In FIG. 3D, only the partial image frame in the image frame is reversed left and right. Therefore, in FIG. 3D, only the image content of the image object I5 is the same as the image object I5 in the image frame of FIG. 3A, and the remaining image objects I1~ I4 is opposite to the image objects I1 to I4 in the image screen of Fig. 3A, respectively.

Similarly, FIG. 3E and FIG. 3F are schematic diagrams of up-and-down inversion and partial up-and-down inversion of the image frame. Therefore, in FIG. 3E, it can be seen that the image objects I1 to I5 and the image objects I1 to I5 in FIG. 3B are respectively In the upside down relationship, in FIG. 3F, only the image object I3 is not upside down with respect to the image object I3 in FIG. 3B. In addition, the method of adjusting the image screen may also be combined with the left and right inversion and the up and down inversion, as shown in FIG. 3G. The image in FIG. 3G is to reverse the left and right and the up and down inversion of the entire image, and then on the second display surface. The image screen seen above is in an upside-down relationship with the image screen of FIG. 3A.

For another example, FIG. 3H is a schematic diagram of removing some image objects in the image frame. In FIG. 3H, the image objects I1 and I2 are removed, so that only the left and right sides of the image frame of FIG. 3A can be seen in FIG. 3H. Image objects I3~I5. FIG. 3I is a schematic diagram of combining the left and right images of the image and the partial removal of the image object. In FIG. 3I, the image object I1 is removed, and the entire image is reversed left and right, so that it can be seen and seen in FIG. 3I. The image objects of the 3A have the same image content I2~I5, and the image object I1 is deleted.

FIG. 3J is a schematic diagram of changing the priority order of the image layer display. It is assumed that the image layer of the image object I2 has a higher priority than the image object I1 in FIG. 3A, and the image layer of the image object I5 has a higher priority than the image object I4. Therefore, in FIG. 3A, the image object I2 is overlaid on the image object I1, and the image object I5 is overlaid on the image object I4. The image processing unit 204 can control the display unit 202 to adjust the image layer display priority order of the image object I1 to be higher than the image object I2, and adjust the image layer display priority order of the image object I4 to be higher than the image object I5. Therefore, in FIG. 3J, it can be seen that the image object I1 is covered on the image object I2, and the image object I5 is completely covered by the image object I4, and cannot be seen on the second display surface.

FIG. 3K is a schematic diagram of an image of a first display surface according to another embodiment of the present invention. 3L-3M are schematic diagrams showing an image of a second display surface according to an embodiment of the invention. The difference between FIG. 3K and FIG. 3A is that the image object I3′ in FIG. 3K is larger than the image object I3 in FIG. 3A , and one part of the image object I3 ′ is overlaid on the image object I4 . As shown in FIG. 3L, the image processing unit 204 can control the display unit 202 to display the text information on the image object I1 and overlay the image information on the image objects I2 and I3. It should be noted that the embodiment of FIG. 3L inserts image information and text information into the image frame at the same time, but the actual application is not limited thereto, and the text information may be separately inserted or the image information may be separately inserted into the image frame. The image information inserted therein can be a picture, image or application interface.

In addition, in some embodiments, the image frame adjustment mode for changing the image layer display priority order and inserting image information and text information may be combined at the same time. As shown in FIG. 3M, the image processing unit 204 controls the display unit 202 to adjust the image layer display priority between the image objects I1 and I2 and I4 and I5 (for example, the image object I3 becomes covered by the image object I4, and the image object I2 becomes covered by the image object I1), and text information is also inserted into the image objects I1 and I4, and image information is inserted into the image objects I2 and I3.

It is worth noting that the above-mentioned inversion application is not limited to the inversion of the image object, and the inserted text information can also be reversed. For example, the shooting time displayed on the general photo may be correctly displayed on the front and back of the display device 200, or may be a movie subtitle on a movie or a television, and may be displayed on the front and back of the display device 200. Display correctly, without the fact that one side is opposite. In addition, it is also possible to invert only part of the image element or text information, for example, only the title of the article or the subject of a sentence.

In addition, although the embodiment of the above embodiment only exemplifies a combination of partially adjusted image frames, the practical application is not limited thereto. Those skilled in the art should be able to derive other combined embodiments of the adjusted image frames according to the above embodiments, and thus will not be further described herein. By adjusting the display content of the video screen according to the viewing position of the user, the convenience of the display device 200 can be improved in response to various situations when the display device is actually used.

Allows the user to see important meetings or to-do items for the month on the back of the mobile electronic device after flipping the mobile electronic device to the face.

For example, FIG. 5 is a schematic diagram of a display screen of a mobile electronic device according to another embodiment of the present invention. Referring to FIG. 5, the display device of the mobile electronic device of the present embodiment also has the characteristics of a transparent display screen. It is assumed that the left image of FIG. 5 is an image screen displayed by the display device of the mobile electronic device when the user views the mobile electronic device from the front side (assumed to be the first display surface), and the right image of FIG. 4 is the user from the back ( The second display surface is assumed to be an image screen displayed by the display device of the mobile device when the mobile electronic device is viewed. The image frame of the display device includes image objects A1~A4, the image object A1 is a graphic image of the application program, the image objects A2 and A3 are picture images, and the image object A4 is a background image.

As shown in FIG. 5, when the user flips the mobile electronic device to view the transparent display screen of the mobile electronic device from the back, the image processing unit 204 adjusts the display content of the video screen according to the position of the user with respect to the display device 200. The display priority order of the image objects A1~A3 is also changed. The display priority order of the image objects A1~A3 shown in the left figure of Fig. 4 is A1>A2>A3, and the image object A1~ in the right picture of Fig.4 The display priority of A3 changes to A3>A2>A1. In addition, the image object A4 (background image) is also removed to present a white image. By directly flipping the mobile electronic device, the characteristics of the display content of the transparent display screen can be changed, so that the user can experience the most intuitive manipulation mode, and the convenience of the mobile electronic device is greatly improved.

It should be noted that the applications illustrated in FIG. 4 and FIG. 5 are merely exemplary embodiments, and the actual application is not limited thereto. For example, most of today's smart phones have the ability to play music, and can display information about playing songs on the screen, such as album cover, lyrics, performers, and so on. When the embodiment of the present invention is applied to playing music, when the user views the transparent display screen of the mobile electronic device from the front, the transparent display screen displays the album cover, and when the user flips the mobile electronic device, the mobile electronic device is viewed from the back. When the screen is transparently displayed, the display content of the image screen is adjusted to the information related to the playing of the song, and the image is reversed so that the user can have an intuitive manipulation effect like watching a CD album. In addition, the display device 200 is not limited to being applied to the mobile electronic device, and may be another electronic product having a first display surface and a second display surface opposite to each other, such as a liquid crystal display screen, a notebook computer, Tablets and more.

Furthermore, although the above embodiments all use the transparent display screen to describe the display device, the actual application is not limited thereto. The display unit 202 can also be a general non-transparent display screen (such as a liquid crystal screen) having a first display surface and a second display surface opposite to each other. For example, when the user moves from the side of the first display surface to the side of the second display surface or the placement state of the display device changes, the image processing unit 204 controls the display unit 202 to perform image left-right inversion and image up-and-down inversion on the image frame. , partial image left and right inversion, partial image upside down, changing image layer display priority order, removing part of image layer, inserting image information, and inserting text information, or a combination thereof, and displaying the adjusted image screen On the second display surface. The effect of implementing the above-mentioned intuitive manipulation can also be achieved. The detailed image frame adjustment mode and application mode are similar to the embodiment of the transparent display screen disclosed above, and those skilled in the art should be able to infer from the above embodiments. The embodiment is therefore not described here.

FIG. 6 is a schematic diagram of a display device according to another embodiment of the present invention. Referring to FIG. 6 , the display device 600 of the present embodiment is different from the display device 200 of FIG. 2 . The display device 600 further includes a detecting unit 602 coupled to the image processing unit 204 . Further, the position of the user relative to the display device 600 or the placement state of the display device 600 can be obtained by the detecting unit 602. The detecting unit 602 can be, for example, one of a ring camera, a gravity sensor, a microphone, a camera, an infrared distance sensor, a touch panel, and a dynamic sensor, or a combination thereof. The microphone, the camera, the infrared distance sensor, the touch panel, and the dynamic sensor may be, for example, disposed on one side of the first display surface or the second display surface of the display unit 202, or on the first display surface. And the second display surface is arranged on both sides.

When the microphone, the camera, the infrared distance sensor, the touch panel, and the dynamic sensor are disposed on both sides of the first display surface and the second display surface, the detecting unit 602 may be detected according to the detected user. To determine the location of the user. That is, if the detecting unit 602 disposed on the side of the first display surface detects the user, it is determined that the user is on the side of the first display surface. If the detecting unit 602 disposed on the side of the second display surface detects the user, it is determined that the user is on the side of the second display surface.

By combining the detection unit 602 on the first display surface and the second display surface and the above-mentioned image inversion technique, many different applications can be developed, giving the user different usage feelings. For example, it is assumed that the display device 200 is applied to a handheld phone, and the detecting unit 602 is a touch sensor. When the user places the handheld phone at the ear, if the front touch sensor (assuming the first display surface) detects a large touch area or detects the shape of the ear, the call can be made. The name of the other party is retained, and other image objects are removed, and the name of the other party is reversed and displayed on the back side (ie, the second display surface), so that others know who the caller is. What's more, you can also display content that is not related to the call on the back, such as today's weather or time information.

If the microphone, the camera, the infrared distance sensor, the touch panel, and the motion sensor are disposed on only one of the first display surface or the second display surface, the detection unit 602 can detect the user according to whether the detection unit 602 detects the user. Determine the location of the user. In other words, it is assumed that the microphone, the camera, the infrared distance sensor, the touch panel or the motion sensor are disposed on the side of the first display surface, such as a microphone, a camera, an infrared distance sensor, a touch panel or a motion sensor. When the user is detected, the user is judged to be on the side of the first display surface. If the user is not detected by the microphone, the camera, the infrared distance sensor, the touch panel, and the motion sensor, the user is judged to be on the side of the second display surface. It is worth noting that since the front and back sides of the touch panel disposed on one side can have different touch sensing sensitivities, even if the touch panel is only disposed on one side, different touch surfaces can be sensed differently. The touch sensing intensity is used to determine the position of the user.

In addition, the ring camera has a 360-degree shooting angle, so it can be judged according to the image area of the user it detects. For example, as shown in the captured image of the ring camera of FIG. 7, it is assumed that the image area in the upper frame in the figure is the image captured in the direction of the first display surface, and the image area in the lower frame is the direction of the second display surface. The captured image can be judged by recognizing the image appearing in the two boxes. For example, in FIG. 7, the user's avatar appears in the lower frame, that is, the user is located on the side of the second display surface.

Furthermore, the gravity sensor can sense the tilt state of the display device 600, which can be applied to the mobile electronic device as described in FIG. 6 to sense the position of the user relative to the display device by sensing the action of the flipper to flip the mobile phone. Whether it changes. In some embodiments, the display device can also be applied to a rotating mechanism, such as a notebook computer having a rotary display panel (or a rotary transparent display panel) as shown in FIG. 8, and the detecting unit 602 can also detect The rotation angle of the display panel is measured to detect the position of the user relative to the display device 600.

It should be noted that the various detection units listed above may be mixed according to the application situation of the display device 600 to achieve an optimal sensing effect. For example, the mobile electronic device using the gravity sensor can also be detected by using an infrared distance sensor and a touch panel, or the display device shown in FIG. 9 can be matched with a camera, a microphone, and an infrared distance sensor. And a touch panel to detect the position of the user relative to the display device.

Those skilled in the art should be able to infer different detection combinations according to the teachings of the above embodiments, and therefore will not be described again.

The microphone, the camera, the infrared distance sensor, the touch panel, the light sensor, the angle sensor, and the dynamic sensor are disposed on one side of the first display surface or the second display surface, or are first Both the display surface and the second display surface are arranged. If the display device is a rotary display panel (or a rotary transparent display panel), the rotation angle of the rotary display panel (or the rotary transparent display panel) can also be detected to detect the relative of the user. At the position of the display device.

Next, the image screens on the first display surface and the second display surface are adjusted in accordance with the state of use of the display device (step S1004). For example, when the display device is a general non-transparent display panel, when the user moves from the side of the first display surface to the side of the second display surface, or when the display state of the display device is changed (for example, the display is placed Or reverse playback), performing image left and right inversion on the image frame (including image objects or text information), inverting the image up and down, reversing the partial image left and right, inverting the partial image up and down, changing the image layer display priority order, and removing part of the image. The action of layer, insertion of image information, and insertion of text information or a combination thereof, and displaying the adjusted image frame on the second display surface. If the display device is a transparent display panel, it is only necessary to perform image left and right inversion on the image frame, image upside down, partial image left and right inversion, partial image upside down, change image layer display priority order, and remove part of image. The action of layer, insertion of image information, and insertion of textual information or a combination thereof.

The actual application embodiment may be, for example, that a light sensor is disposed on the frame of the display device, and when the back surface receives the light, it is known that the front side is facing the desktop, so that the image image of the front display can be reversed and Displayed on the back. For example, an infrared distance sensor can be disposed on the front surface of the display device, and when it detects that the distance result is 0, it means that the front side is facing the desktop, so that the image of the front side of the original display can be reversed, and It is shown on the back.

In some embodiments, the content of the first display surface and the second display surface may be completely different but have a corresponding relationship defined by a file or a program or an operating system, but both display surfaces conform to the current state. For example, one side is the CD cover and the other side is the CD cover or one side is the interface of the telephone call content and the other side is the weather display.
