Detailed Description
For a clearer description of the present application, the present application is further described below with reference to preferred embodiments and the accompanying drawings. Like parts in the drawings are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is intended to be illustrative, and not restrictive, and that this invention is not to be limited to the specific embodiments shown.
The display electrode of the display area adopts a block design, such as a liquid crystal display panel, and the common electrode of the display area is divided into a plurality of sensing units, namely Sensor blocks. The applicant finds that the display difference exists between the edge position and the non-edge position of the Sensor block, and the transverse lines exist in the gray-scale picture, so that the display panel has the problem of poor display. Specifically, as shown in fig. 2a to 2d, the cross grain display is related to the duty ratio of the clock signal, wherein, referring to fig. 2a, when the duty ratio of the clock signal is 0 to 12.5%, the TFT of the pixel Gn of the nth row is not affected by other rows before being turned off, and when the pixels in the middle position and the edge position of the Sensor block are charged, the common electrode is consistent under the condition of Gout pulling, and the display panel does not display the cross grain; referring to fig. 2b, when the duty ratio of the clock signal is 12.5% -25%, the TFT of the pixel gn+1 of the nth row is already turned on before the TFT of the pixel Gn of the nth row is turned off, so that the common electrode is affected by the charge of the pixel gn+1 row, the recovery time of the common electrode of one row at the edge of the Sensor is different from that of the middle row of the Sensor block, and the Sensor cross stripe appears on the display panel; referring to fig. 2c, when the duty ratio of the clock signal is 25% -37.5%, before the TFTs of the Gn pixels are turned off, the TFTs of gn+1 pixels and gn+2 pixels are turned on, the common electrode is affected by charging gn+1 pixels and gn+2 pixels, the recovery time of the two common electrodes at the edge of Sensor is different from that of the middle row of Sensor, and the Sensor cross stripe appears on the display panel; referring to fig. 2d, when the duty ratio of the clock signal is 37.5% -50%, before the TFTs of the Gn pixels are turned off, the TFTs of the gn+1 pixels, gn+2 pixels and gn+3 pixels are turned on, and the common electrode is affected by the charge of gn+1 pixels, gn+2 pixels and gn+3 pixels, the recovery time of the Sensor edge three lines of common electrodes is different from that of the Sensor middle line, and the Sensor cross lines appear on the display panel. In summary, the applicant has further found that the larger the duty cycle of the clock signal, the more the number of rows there is a difference between the edge of the sensor block and the intermediate display, and the more obvious the phenomenon is when the sensor cross-stripe occurs on the display panel.
To this end, an embodiment of the present application provides a timing control method applied to an in-cell display panel in which display electrodes and touch electrodes are multiplexed, the display panel including pixels arranged in an array, and a plurality of rows of gate lines and a plurality of columns of data lines driving the pixels to emit light, the method including:
the time schedule controller caches one frame of display data;
the timing controller outputs a first driving signal and a second driving signal within a frame of display data refreshing time, wherein the first driving signal is used for sequentially outputting grid driving scanning signals to odd-numbered row grid lines of the display panel, the second driving signal is used for sequentially outputting grid driving scanning signals to even-numbered row grid lines of the display panel, and the scanning directions of the first driving signal and the second driving signal are opposite.
According to the embodiment, one frame of display data is cached in the time sequence controller, so that the first driving signal and the second driving signal are output within one frame of display data refreshing time, reverse scanning of odd lines and even lines of the display panel is realized, and the defect of transverse lines caused by continuous line display is improved, so that the problems in the prior art are solved, and the display device has a wide application prospect.
In one embodiment, as shown in fig. 3, the display panel includes a plurality of pixel units arranged in an array, each pixel unit including a pixel 320 and a thin film transistor 310 driving the pixel 320, and a plurality of rows of gate lines 100 and a plurality of columns of data lines 200 driving the pixel 320 to emit light.
It should be noted that, the time sequence control method of the embodiment is applicable to an embedded display panel with multiplexing display electrodes and touch electrodes, when the display panel is a liquid crystal display panel LCD, the display electrodes are common electrodes, and when the display panel is an electroluminescent diode display panel, the display electrodes are cathodes loaded with common voltages.
As shown in fig. 4, the timing control method of the present embodiment includes:
s10, caching one frame of display data by a time sequence controller;
s20, the time schedule controller outputs a first driving signal and a second driving signal in a frame of display data refreshing time, wherein the first driving signal is used for sequentially outputting grid driving scanning signals to odd-numbered row grid lines of the display panel, the second driving signal is used for sequentially outputting grid driving scanning signals to even-numbered row grid lines of the display panel, and the scanning directions of the first driving signal and the second driving signal are opposite.
It should be clear to a person skilled in the art that in order to implement a two-way driving scan signal, the display panel comprises a first GOA circuit and a second GOA circuit arranged opposite to each other, for example, a first GOA circuit and a second GOA circuit arranged on both sides of the display panel, wherein the first GOA circuit is responsive to the first driving signal and the second GOA circuit is responsive to the second driving signal.
In a specific example, taking a display refresh frequency of 60Hz as an example, the refresh time of one frame of display data is 16.67ms, and the scanning direction of the first driving signal is forward, that is, the first GOA circuit transmits the gate driving signals to the odd rows of the driving display panel in order from small to large so as to realize the forward scanning of the odd rows, as shown in fig. 5, that is, H1, H3, H5 … … H767; the scanning direction of the second driving signal is reverse, that is, the second GOA circuit transmits the gate driving signal to the even-numbered rows driving the display panel in order from large to small so as to realize the reverse scanning of the even-numbered rows, that is, H768, H766, H764 … … H2.
In this embodiment, the first driving signal is controlled to drive the odd lines to realize forward scanning, and the second driving signal is controlled to drive the even lines to realize reverse scanning, so as to improve the display effect of the display panel and alleviate the cross stripe defect in the prior art
In an alternative example, the scanning direction of the first driving signal is reverse, that is, the first GOA circuit transmits the gate driving signal to the odd-numbered rows driving the display panel in order from large to small so as to implement the reverse scanning of the odd-numbered rows, as shown in fig. 5, that is, H767, H765, H763 … … H1; the second GOA circuit transmits the gate driving signals to the even-numbered rows of the driving display panel in order from small to large in the forward direction of the scanning direction of the second driving signals, so that the forward scanning of the odd-numbered rows, namely H2, H4, H6 … … H768, is realized.
It should be noted that, the scanning direction of the odd-numbered line gate lines or the even-numbered line gate lines is not limited, and when the scanning directions of the odd-numbered line gate lines and the even-numbered line gate lines are opposite, the display effect of the display panel can be improved, and the transverse streak phenomenon in the prior art can be alleviated.
In one specific example, the timing controller also outputs a clock signal, wherein the duty cycle of the clock signal is one of 0-25%, 25% -37.5%, and 37.5% -50%.
Specifically, as shown in fig. 6, when the duty ratio of the clock signal is 0-25%, after the timing control method of this embodiment is applied, the odd-numbered line scanning and the even-numbered line scanning are separated, and the TFT of the pixel Gn of the nth row is not affected by the charging of the pixels of other rows before the TFT of the pixel Gn of the nth row is turned off, so that the pulling of the display electrode at the edge of the Sensor and the pulling at the middle of the Sensor are not different, and the Sensor cross stripe does not appear on the display panel.
Similarly, as shown in fig. 7, when the duty ratio of the clock signal is 37.5% -50%, after the timing control method of this embodiment is applied, the odd-numbered line scanning and the even-numbered line scanning are separated, and although the TFT of the thin film Gn of the nth row pixel is affected by the charge of gn+2 row pixels before the TFT of the thin film Gn of the nth row pixel is turned off, the recovery time of the display electrode is increased by 1H, so that the sensor moire phenomenon can be significantly improved.
The present example can improve the moire phenomenon of the display panel due to the continuous line display by adopting the reverse scanning method.
It should be noted that, although the improvement of the sensor cross stripe phenomenon is obvious, when the positive and negative scanning of the odd-numbered row gate lines and the even-numbered row gate lines are intersected, the sensor block at the intersection position is affected by the positive scanning gate lines and the negative scanning gate lines at the same time, for example, the rows G383 to G386 in the positive scanning and the negative scanning of the odd-numbered row in fig. 8 are mutually affected, so that the middle black line appears on the display panel.
For this, in an alternative example, the refresh time of one frame of display data includes a plurality of display periods and a plurality of touch sensing periods that are set at intervals, and the number of the touch sensing periods is an odd number, and the timing controller synchronously outputs the first driving signal and the second driving signal during the refresh time of one frame of display data. The touch sensing period is only used for touch control, and the display period is only used for display.
It should be noted that, the number of the display periods is not specifically limited, and may be odd or even, and those skilled in the art should select an appropriate number according to the actual application requirement, which is not described herein.
In a specific example, the display refresh frequency of the display panel is 60Hz, and the refresh time of one frame of display data includes 16 display periods and 15 touch sensing periods which are set at intervals, as shown in table 1, specifically:
the display refresh time of one frame is 16.67ms, the display period is represented by "D", the touch sensing period is represented by "pit", the time schedule controller synchronously outputs the first driving signal and the second driving signal in the display data refresh time of one frame, and the odd-numbered lines and the even-numbered lines fall at the position of the 8 th touch sensing period when in reverse scanning intersection, namely the "pit stopping time" in FIG. 9, at the moment, the Sensor block is a touch electrode, and the display panel does not display, so that the middle black line appearing due to intersection of the two is eliminated.
In this example, by setting the touch sensing period to be odd and the display period to be even, under the condition that the first driving signal and the second driving signal are synchronous, the odd-row grid lines and the even-row grid lines fall at the position of the touch sensing period when being reversely scanned and intersected, so that the middle black line appearing due to intersection of the odd-row grid lines and the even-row grid lines is removed.
TABLE 1
In an alternative embodiment, the display refresh frequency of the display panel is less than or equal to 120Hz, and the number of the touch sensing periods is one of 7, 9, 11, 13, and 15.
In this embodiment, the number of touch sensing periods may be set to the above number within the display refresh time of one frame of display data, and it is worth noting that, the larger the display refresh frequency is, the smaller the number of touch sensing periods is, for example, the 120HZ corresponds to 7 or 9, the 90HZ corresponds to 11 or 13,60HZ corresponds to 13 or 15, and those skilled in the art should select an appropriate touch sensing period and display period according to the actual application requirement, which is not described herein again.
A second embodiment of the present application provides a timing controller applied to an in-cell display panel for multiplexing display electrodes and touch electrodes, the display panel including pixels arranged in an array, and a plurality of rows of gate lines and a plurality of columns of data lines for driving the pixels to emit light, the timing controller including

According to the embodiment, one frame of display data is cached in the time sequence controller, so that the first driving signal and the second driving signal are output within one frame of display data refreshing time, reverse scanning of odd lines and even lines of the display panel is realized, and the defect of transverse lines caused by continuous line display is improved, so that the problems in the prior art are solved, and the display device has a wide application prospect.
