A method for driving a display panel includes generating data signals to drive pixels in the display panel. The pixels in the display panel are arranged in a matrix. In addition, the voltage values of the data signals are adjusted to render a sum of voltage values of the data signals in a unit area as zero.

摘要:
A pixel circuit includes a first sub-pixel and a second sub-pixel. The first sub-pixel is coupled to a scan line and a data line, so as to determine whether to be enabled according to a first scan signal transmitted on the scan line, and whether to be driven according to a data signal transmitted on the data line. The second sub-pixel is coupled to the scan line, so as to determine whether to be enabled according to the first scan signal. The data signal is in a first state when the first scan signal is in a pre-charged period. The data signal is in a second state during a time interval after the pre-charged period is over and before the first scan signal enters a turn-on period. Voltage polarities of the first state and the second state are opposite. The pixel design can improve color shift and frame flicker.

A liquid crystal display (LCD) panel with color washout improvement. In one embodiment, the LCD panel a plurality of pixels, {Pn,m}, spatially arranged in the form of a matrix, n=1, 2, . . . , N, and m=1, 2, . . . , M, and N, M being an integer greater than zero, each pixel Pn,m comprising at least a first sub-pixel, Pn,m(1), having a sub-pixel electrode and a second sub-pixel, Pn,m(2), having a sub-pixel electrode. The plurality of pixels, {Pn,m}, is configured such that when a gray level voltage associated with a gray level, g, of an image to be displayed on a pixel is applied to the pixel Pn,m, a potential difference, ΔV12(g), is generated in the sub-pixel electrodes of the first and second sub-pixels of the pixel Pn,m. The potential difference, ΔV12(g) varies with the gray level g of the image to be displayed on the pixel, where g=0, 1, 2, . . . , R corresponding to one of the shades of grey of the image expressed in h bits, h being an integer greater than zero and R=(2h−1).
