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.
