Abstract
本发明实施例提供一种液晶显示器的驱动方法、驱动电路及液晶显示器，方法包括在行反转或点反转的驱动方式中，将任一帧的时间分成两个操作时间段；在一个所述操作时间段内，依次打开奇数行扫描线，将奇数行数据信号写入奇数行像素，并在另一个所述操作时间段内，依次打开偶数行扫描线，将偶数行数据信号写入偶数行像素。对液晶显示器的奇数行扫描线和偶数行扫描线分别进行驱动，由于每一次驱动是在一帧的时间的二分之一长度内完成的，像素的负载电容在一个操作时间段内不需完成从正电压到负电压的转换，而最多只是完成了从正电压或者负电压到基准电平的转换，因此根据功耗公式可以知道降低了液晶显示器的数据逻辑的功耗。
Embodiments of the present invention provide a driving method, a driving circuit, and a liquid crystal display for a liquid crystal display. The method includes dividing the time of any frame into two operating time periods in a row inversion or dot inversion driving mode; In the above operation time period, turn on the scan lines of odd rows in sequence, write the data signals of odd rows into pixels in odd rows, and in the other operation time period, turn on the scan lines of even rows in sequence, and write the data signals of even rows into even row of pixels. The odd-numbered scanning lines and the even-numbered scanning lines of the liquid crystal display are driven separately. Since each driving is completed within half the length of one frame, the load capacitance of the pixel does not need to be completed within an operation period. The conversion from positive voltage to negative voltage only completes the conversion from positive voltage or negative voltage to reference level at most. Therefore, according to the power consumption formula, it can be known that the power consumption of the data logic of the liquid crystal display is reduced.
Description
Technical Field
The invention relates to a liquid crystal display technology, in particular to a driving method and a driving circuit of a liquid crystal display and the liquid crystal display.
Background
Power consumption is an important performance index of the lcd, and an important component thereof is logic power consumption of the data signal.
In a liquid crystal display, common storage capacitors include a gate storage capacitor (Cs on gate) and a common storage capacitor (Cs on common), and the difference between the gate storage capacitor and the common storage capacitor is that the gate storage capacitor is wired by a gate and the common storage capacitor is wired by a common electrode. Each Thin Film Transistor (TFT) is connected to a storage capacitor Cst, representing a display point, and a basic display cell (pixel) requires three such points representing the three primary colors of red (R), green (G), and blue (B), respectively; a total of 1024 × 768 × 3 such dots are required for a thin film transistor liquid crystal display (TFT LCD) of 1024 × 768 resolution. The TFTs of each row are turned on in sequence by a waveform sent by a Gate Driver, so that the Source drivers of the entire row charge the points of the entire row to respective required voltages at the same time, and different gray scales are displayed. When the charging of the row is finished, the grid drive turns off the voltage, then the grid drive of the next row turns on the voltage, and then the same row of source drive charges the point of the next row; in this sequence, when the dots of the last row are filled, the charging is started again from the first row. The liquid crystal display with the resolution of 1024 × 768 has 768 rows of gate tracks in total, and 1024 × 3=3072 source tracks; in the liquid crystal display with the update frequency of 60Hz, the display time of each picture is about 1/60=16.67ms, the composition of the picture is 768 rows of gate lines, so the switching time allocated to each gate line is about 16.67ms/768=21.7 μ s, and the source drive charges and discharges the pixel electrode to the required voltage within 21.7 μ s, so that the corresponding gray scale is displayed.
The display voltage in the liquid crystal display is divided into two polarities, one positive polarity and one negative polarity; the voltage of the pixel electrode is higher than that of the common electrode and is called as positive polarity, and the voltage of the pixel electrode is lower than that of the common electrode and is called as negative polarity; either positive or negative polarity will have a set of gray levels of the same intensity. Therefore, when the absolute value of the voltage difference between the upper and lower electrodes is fixed, the gray scales are the same regardless of whether the voltage of the pixel electrode is high or the voltage of the common electrode is high. However, the liquid crystal molecules in these two cases are turned in the opposite directions, and by continuously inverting the liquid crystal molecules, it is possible to prevent the deterioration of the characteristics caused when the liquid crystal molecules are turned to be fixed in one direction all the time. In other words, when the display screen is still moving, the display screen still can be moved by the continuous alternation of the positive and negative polarities, and the liquid crystal molecules are not damaged. Existing inversion implementations include frame inversion, row inversion, column inversion, dot inversion, and the like.
As shown in fig. 1, a storage capacitor Cst and a load capacitor C are disposed between the pixel electrode and the common electrode. The power consumption formula of the data signal is P ═ Cf (Δ V)2Wherein the magnitude of the load capacitance C and the variation frequency f of the data signal are constant. For the conventional row inversion and dot inversion implementations, the voltage applied across the storage capacitor Cst frequently varies between the positive voltage Vp and the negative voltage Vn within a time of one frame, Δ V = Vp-Vn; positive voltage Vp and negative voltageThe absolute values of the pressures Vn are substantially the same.
In order to reduce logic power consumption, in the prior art, an external memory of an embedded chip is deactivated, and only an on-chip RAM is used for accessing image data and codes. Or, in some prior arts, the bistable chiral nematic liquid crystal is activated to a preset initial state, the gray scale image data to be updated is written into the pixel, and then the applied voltage of the pixel is reset to zero, so that the bistable chiral nematic liquid crystal is restored to the stable state corresponding to the gray scale image data.
The prior art has the following problems: in writing data signals into the liquid crystal display, the voltage of the load capacitor needs to be frequently switched between positive and negative voltages, which results in excessive power consumption for writing data signals.

In the method, in one operation time period, a counter is adopted to count the scanning operation executed by each odd-numbered line scanner; and counting the scanning operation performed by each even-numbered line scanner by using the counter in another operation time period.
In the method, in one operation time period, each time the counter counts, the scanning operation is executed corresponding to one odd-numbered line scanner, and all the odd-numbered line scanners execute the scanning operation in the operation time period; in another operation time period, the counter performs a scanning operation corresponding to one even-numbered line scanner every time the counter counts, and all the even-numbered line scanners perform the scanning operation in the operation time period.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the pixel structure includes a load capacitor 3, a storage capacitor 4, a data line 5, a gate line 6, a common electrode 7, a pixel electrode 8, a thin film transistor 9, and a source electrode 10; it should be understood that the source 10 is merely illustrative and that in practice the source/drain electrodes may be interchanged for the thin film transistor 9.
As shown in fig. 2, the scan lines of the panel are divided into odd-numbered scan lines 1 and even-numbered scan lines 2, each of which is connected to an Integrated Circuit (IC) to separately drive the odd-numbered and even-numbered rows of the panel, and include: the odd-numbered scanning lines 1 are connected to the gate drive IC1, and the even-numbered scanning lines 2 are connected to the gate drive IC 2. The gate driver IC1 is an odd row scanner, and the gate driver IC2 is an even row scanner.
An embodiment of the present invention provides a method for displaying a data signal on a liquid crystal display, as shown in fig. 3, the method includes:
and in another of the operation periods, the even-numbered row of scanning lines 2 are sequentially turned on to write the even-numbered row of data signals into the even-numbered row of pixels.
By applying the technical scheme provided, the odd-numbered scanning lines 1 and the even-numbered scanning lines 2 of the liquid crystal display are respectively driven, and because each driving is completed within a half length of one frame time, as shown in fig. 7, the load capacitance 3 of the pixel does not need to complete the conversion from the positive voltage to the negative voltage in one operation time period, but only completes the conversion between the positive voltages or between the negative voltages (at most, from the positive voltage or the negative voltage to the reference level), so that the power consumption of the data logic of the liquid crystal display is reduced according to the power consumption formula. The time of one frame is divided into two equal parts to form two operation time periods of one frame, and after the two equal parts, the odd-numbered row scanning lines 1 and the even-numbered row scanning lines 2 are respectively driven in each operation time period. The odd line data signal or the even line data signal is a pulse scanning signal; wherein the pulsed scanning signal is higher than the reference level or lower than the reference level.
Of course, it will be understood by those skilled in the art that when the total number of scanning lines is odd rather than even, the time of one frame may be divided in proportion to the number of odd and even lines, without requiring exact halving.
In a preferred embodiment, as shown in fig. 4, step 302 specifically includes:
the sequentially opening the odd-numbered scanning lines 1 includes: scanning each odd-numbered line of scanning lines 1 from the top end to the bottom end of the liquid crystal display in sequence;
the sequentially opening the even-numbered rows of scanning lines 2 includes: and scanning each even-numbered row of scanning lines 2 from the top end to the bottom end of the liquid crystal display in sequence.
In other words, the data signal is divided into two parts within one frame time, one part corresponds to the odd-numbered rows of pixel electrodes 8, and the other part corresponds to the even-numbered rows of pixel electrodes 8; and writing corresponding odd line data in the first half frame time, and writing corresponding even line data in the second half frame time.
Power consumption formula P ═ Cf (Δ V) of load capacitor 32Wherein the load capacitance 3 and the signal change frequency are determined. With the technique of the above embodiment, the variation value Δ V of the data signal in the half-frame time is much reduced compared to the dot inversion implementation of the prior art, thereby reducing the power consumption of the data logic.
Applying the provided techniques in an application scenario, comprising:
step 1, dividing the time of a frame into two equal parts to form two operation time periods, wherein each operation time period is half of the frame;
and 3, setting the counter to be 1 for the second half frame, scanning each even-row scanning line 2 connected with the even-row scanner by the even-row scanner, and writing the even-row data signals into the even-row pixels by the system.
In other words, whether the data signal is written to the pixels of the odd-numbered rows or the pixels of the even-numbered rows is switched by switching the value of the counter between 0 and 1; this may also be done in a loop for subsequent frames.
As shown in fig. 5, there may be more than one odd line scanner connected to each of the odd line scan lines 1, or there may be more than one even line scanner connected to each of the even line scan lines 2.
In a preferred embodiment, when there are more than one odd line scanners connected to the odd line scanning lines 1, each odd line scanner is sequentially driven, and each odd line scanner sequentially turns on its own connected odd line scanning line 1 to write the odd line data signal to the corresponding odd line pixel;
when more than one even-numbered line scanner connected with each even-numbered line scanning line 2 is used, each even-numbered line scanner is sequentially driven, and each even-numbered line scanner sequentially opens the even-numbered line scanning line 2 connected with the even-numbered line scanner so as to write the even-numbered line data signals into the corresponding even-numbered line pixels.
When the panel of the liquid crystal display is large and the resolution is high, the odd-numbered scanning line 1 and the even-numbered scanning line 2 may be divided again, the odd-numbered scanning line 1 is connected to the plurality of gate drive ICs 1 (odd-numbered line scanner), and the even-numbered scanning line 2 is connected to the plurality of gate drive ICs 2 (even-numbered line scanner); in the scanning process, the scanning lines 1 in the odd rows are still charged in sequence, and then the scanning lines 2 in the even rows are charged.
In a preferred embodiment, during one of the operation time periods, the scanning operation performed by each odd line scanner is counted by using a counter;
and counting the scanning operation performed by each even-numbered line scanner by using the counter in another operation time period.
And in the time of one frame, circularly counting the scanning operation executed by each scanner in each operation time period by using a counter.
The count bits of the counter are set according to the number of odd and even line scanners to multiply count a control signal output from the counter, such as a vertical signal start pulse (STVP), which is a signal of one pin of a logic driver of the TFT LCD.
In a preferred embodiment, during one of the operation time periods, the counter performs a scanning operation corresponding to one of the odd line scanners every time the counter counts, and all of the odd line scanners perform the scanning operation during the operation time period;
in another operation time period, the counter performs a scanning operation corresponding to one even-numbered line scanner every time the counter counts, and all the even-numbered line scanners perform the scanning operation in the operation time period.
As shown in fig. 6, during one operation period, the odd-numbered line scanner performs scanning operation in time sequence, and sequentially sends out the scanning signals SG1，SG3，SG5,.G2n-1；
If the number of the odd line scanners is more than one, namely, the scanning signals are respectively sent out by each odd line scanner to turn on the TFT and receive the data signals from the corresponding data line, all the odd line scanners should finish sending out the scanning signals in one operation time period;
in another operation time period, the even-numbered line scanner executes scanning operation according to time sequence and sends out scanning signals S in sequenceG2，SG4，SG6,.G2n；
If the number of the even-numbered line scanners is more than one, that is, the scanning signals are respectively sent out by each even-numbered line scanner to turn on the TFT and receive the data signals from the corresponding data line, all the even-numbered line scanners should finish sending out the scanning signals in the other operation time period. By applying the provided technology, in an application scene, more than one odd line scanner and more than one even line scanner are arranged; taking a liquid crystal display with a resolution of 1024 × 768 as an example, 768/2=384 scanning lines 1 in the odd rows and 768/2=384 scanning lines 2 in the even rows.
Without loss of generality, if one scanner is set to be connected with 32 scanning lines, there are 12 odd-line scanners and 12 even-line scanners.
Equally dividing the time of one frame into 2 operation time periods, wherein each operation time period is divided into 12 sub-operation time periods, and each sub-operation time period is 1/24 times of the time of one frame and is distributed to one scanner;
the counter can record a total of 12+12=24 numbers.
The method comprises the following steps:
and step 1, in the process that the counting of the counter is 0-11, the counter drives each odd-numbered line scanner in sequence, and each odd-numbered line scanner drives the odd-numbered line scanning line 1 connected with the counter in sequence. Wherein,
when the count is 0, writing a data signal into the pixels in the odd rows connected to the 1 st odd row scan line 1;
when the count is 1, writing a data signal into the pixels in the odd rows connected to the 2 nd odd row scan line 1;
and so on, until when the count is 11, writing a data signal into the pixels in the odd rows connected to the 12 th odd-row scanning line 1;
the first half of the time of one frame ends.
And 2, in the process that the counting of the counter is 12-23, the counter sequentially drives each even-numbered line scanner, and each even-numbered line scanner sequentially drives the even-numbered line scanning line 2 connected with the counter. Wherein,

when the count is 13, writing a data signal to the 2 nd even-numbered row pixels;
and so on until, at a count of 23, writing a data signal to the 12 th even-row pixel;
