Embodiment Construction

[0033] In order to illustrate the present application more clearly, the present application will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present application.

[0034] The display electrodes in the display area adopt a block design, such as a liquid crystal display panel, and its common electrode is divided into several sensing units, that is, Sensor blocks. After research, the applicant found that there is a display difference between the edge position and the non-edge position of the Sensor block, and there are horizontal stripes in the grayscale picture, which leads to the problem of poor display on the display panel. Specifically, such as Figure 2a ~ Figure 2d As shown...

Abstract

The embodiment of the invention discloses a time sequence control method, a time sequence controller, a storage medium and computer equipment, the time sequence control method of one embodiment is applied to an embedded display panel for multiplexing a display electrode and a touch electrode, and the display panel comprises pixels arranged in an array. The multiple rows of grid lines and the multiple columns of data lines drive the pixels to emit light, and the time schedule controller caches a frame of display data; the time schedule controller outputs a first driving signal and a second driving signal within the refreshing time of one frame of display data, the first driving signal is used for sequentially outputting grid driving scanning signals to odd-numbered rows of grid lines of the display panel, the second driving signal is used for sequentially outputting a gate driving scanning signal to an even number of rows of gate lines of the display panel, and the scanning direction of the first driving signal is opposite to that of the second driving signal. Therefore, the display effect of the display panel is improved through reverse scanning of odd-numbered lines and even-numbered lines, and poor cross grains in the prior art are relieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a timing control method, timing controller, storage medium and computer equipment. Background technique [0002] In-cell touch (In-cell Touch) refers to embedding the function of the touch panel into the display panel, which adopts the method of multiplexing the display electrodes and touch electrodes of the display panel. Control electrode multiplexing. Specifically, such as figure 1 As shown, the common electrodes of the display area are divided into several sensing units, that is, Sensors, which are connected to the touch chip by TX lines (driver circuit lines), wherein, on the one hand, the sensing units are connected to the common electrodes as display electrodes in the display stage. On the other hand, it is used as the sensing electrode to identify the touch operation in the touch stage. Since the touch operation will cause the capacitance of the sensing unit ...
