Embodiment 1

[0035] A display control method provided by an embodiment of the present invention is introduced in detail.

[0036] The display device includes a plurality of pixel units arranged in an array and common electrodes 102, 104, 106 connected to corresponding row pixel units 101, 103, 105, see figure 1 The display device shown.

[0037] In this embodiment, the voltage on a row of pixel units 101 is affected by the common electrode 102. Since the voltage value of the common electrode 102 is different in display mode and touch mode, the voltage applied to a row of pixel units 101 will fluctuate. As a result, the display brightness of the pixel unit 101 is different when the display mode and the touch mode are switched. If the voltages of the common electrodes 102 and 104 in two adjacent rows are different, the display brightness of the pixel units 101 and 103 in the two adjacent rows will be different, and horizontal stripes will be generated.

[0038] refer to figure 2 , which ...

Abstract

The invention provides a display control method, a feedback circuit, a display device and an IC (integrated circuit). The display device comprises a plurality of pixel units distributed in an arrayed manner, and common electrodes correspondingly connected with rows of the pixel units. The method comprises the steps of selecting the common electrodes of the two adjacent rows, collecting voltage of the common electrodes of the two adjacent rows, comparing the collected voltage of the common electrodes of the two adjacent rows, obtaining a comparison result, and when the comparison result meets a preset condition, compensating the input voltage of the pixel units corresponding to the common electrodes of the two adjacent rows according to the comparison result to allow the voltage applied to the pixel units of the two adjacent rows to be equal. After compensation, the voltage across the pixel units of the two adjacent rows is equal, the display brightness of the pixel units of the two adjacent rows is the same, and therefore, an across grain is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display control method, a feedback circuit, a display device and an IC circuit. Background technique [0002] Compared with the conventional method of disposing the touch panel on the liquid crystal panel, the research of integrating the function of the touch panel with the liquid crystal panel is becoming more and more popular. The integration of touch panel and liquid crystal panel includes "In-cell" method and "On-cell" method. In-cell refers to the method of embedding touch panel functions into liquid crystal pixels. On-cell refers to the method of embedding the touch panel function between the color filter substrate and the polarizer. [0003] The market share of the Incell technology shown at this stage is increasing year by year, but the 120Hz time-sharing scanning solution of the Incell solution has always had the problem of fixed horizontal stripes. E...
