发明名称 Liquid crystal display capable of rendering video data in accordance with a rendering structure of a double rate driving panel
摘要 A liquid crystal display includes a liquid crystal display panel having a pixel array including a first group of liquid crystal cells connected to odd-numbered gate lines and a second group of liquid crystal cells connected to even-numbered gate lines and a data driving circuit including a latch array. Each liquid crystal cell of the second group shares a data line with one liquid crystal cell of the first group adjacent to the liquid crystal cell of the second group in an extension direction of the gate lines. The latch array delays only second group data to be applied to the liquid crystal cells of the second group among digital video data for one horizontal line by about one half horizontal period in response to a data rendering control signal.

主权项 1. A liquid crystal display comprising: a liquid crystal display panel having a pixel array including a first group of liquid crystal cells connected to odd-numbered gate lines and a second group of liquid crystal cells connected to even-numbered gate lines, wherein each liquid crystal cell of the second group is configured to share a data line with one liquid crystal cell of the first group; a data driving circuit configured to drive data lines of the pixel array in a time-division manner, the data driving circuit including a latch array; and a timing controller configured to supply digital video data to the data driving circuit and control operation timing of the data driving circuit, wherein the latch array delays only second group data to be applied to the liquid crystal cells of the second group among the digital video data for one horizontal line by one half horizontal period in response to a data rendering control signal and temporally separates first group data to be applied to the liquid crystal cells of the first group from the second group data to be applied to the liquid crystal cells of the second group, wherein the data rendering control signal received from the timing controller includes a first source output enable signal for controlling output timing of the first group data, and a second source output enable signal for controlling output timing of the second group data, and wherein the second source output enable signal is generated only once every one horizontal period, and generated later than the first source output enable signal by one half horizontal period.
