Abstract: A method of compensating pixel data for a display panel includes the steps of: receiving a first pixel data and a second pixel data respectively corresponding to two adjacent data lines of the display panel; generating a compensation pixel data by searching a lookup table based on the first pixel data and the second pixel data; and transmitting the compensation pixel data to one of the two adjacent data lines to be displayed on the display panel.

Abstract: A display system includes a display device and a driver circuit. The display device has a first panel and a second panel, wherein the first panel and the second panel are disposed with a gap therebetween. The driver circuit is coupled to the display device and includes a protection circuit. The protection circuit, coupled to the second panel of the display device, is configured to generate a gray scale data to be outputted to a pixel among a plurality of pixels of the second panel according to a luminance corresponding to the pixel and according to whether a protection function is enabled.

Abstract: A driver circuit is coupled to a dual cell panel having a first cell and a second cell superposed on each other. The driver circuit includes a second cell processor and a first cell processor. The second cell processor is configured to generate a gray scale data for the second cell. The first cell processor includes a pixel data compensation circuit and a white tracking compensation circuit. The pixel data compensation circuit is configured to compensate an image data for the first cell according to a brightness of the image data. The white tracking compensation circuit is configured to compensate the image data for the first cell according to a color temperature of the gray scale data.
