摘要： A bistable display and a method of driving a panel thereof are provided. The present invention would set the driving information lookup table (DLUT) and the corresponding reference information relating to each frame of the bistable display in advance, and look up the previous frame driving data and/or the current frame driving data of the panel according to the set reference information and thus obtaining information for driving each pixel of the panel. Accordingly, not only the memory space of the built-in DLUTs can be substantially reduced and thus saving the usage cost of memories, but also the time for download DLUTs from the external memory unit by the timing controller (T-con) can be reduced so as to promote the operation performance of the whole bistable display and thus further increasing the speed of the panel.

摘要： A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a liquid crystal display panel including data lines and gate lines crossing each other and liquid crystal cells, a timing control signal generating unit, a data drive circuit supplying a data voltage to the data lines, and a gate drive circuit. The timing control signal generating unit generates a first gate timing control signal for controlling a scan direction of the liquid crystal display panel in a sequential direction and a second gate timing control signal for controlling the scan direction in a reverse sequential direction. The gate drive circuit supplies a gate pulse to the gate lines while a shift direction of the gate pulse changes in response to the first and second gate timing control signals.
