Low power driving system and timing controller for display device
Disclosed are a low power driving system and timing controller for a display device. The low power driving system for a display device may include a timing controller configured to transmit a packet to which one of first option information corresponding to a static pattern or second option information corresponding to a dynamic pattern is applied, and a source driver configured to receive the packet and to perform a low power mode corresponding to the static pattern based on the first option information or adaptive charge sharing corresponding to the dynamic pattern based on the second option information.
Methods for driving electro-optic displays
An electro-optic display having a plurality of pixels is driven from a first image to a second image using a first drive scheme, and then from the second image to a third image using a second drive scheme different from the first drive scheme and having at least one impulse differential gray level having an impulse potential different from the corresponding gray level in the first drive scheme. Each pixel which is in an impulse differential gray level in the second image is driven from the second image to the third image using a modified version of the second drive scheme which reduces its impulse differential The subsequent transition from the third image to a fourth image is also conducted using the modified second drive scheme but after a limited number of transitions using the modified second drive scheme, all subsequent transitions are conducted using the unmodified second drive scheme.
