Embodiment Construction

[0042] The main idea of ​​the present invention is to adjust the load control signal output from the display control circuit of the liquid crystal display to the data drive circuit, the load control signal can not only control the data drive circuit to output the data voltage for driving each row of pixels, more importantly, the load control The circuit can also control the data driving circuit to adjust the voltages on the multiple data lines. Specifically, the load control signal has multiple first trigger marks and multiple second trigger marks. Please refer to the first output trigger mark of the data voltage of the pixel described in the first embodiment of the liquid crystal display in this invention for the explanation of changing lines, and a plurality of lines used to trigger the output drive polarity inversion of the data driving circuit (for For the explanation of the non-polarity inversion line, please refer to the second output trigger mark of the data voltage of ...

Abstract

The invention discloses a liquid crystal display which comprises a liquid crystal panel, a display control circuit and a data driven circuit, wherein the display control circuit is used for receiving an image signal and generating a time sequence signal and a data signal according to the image signal; the data driven circuit is used for receiving the time sequence signal and the data signal so asto form a plurality of data voltages; and before the data voltage for driving a non-polar inversed pixel is pre-output, the data driven circuit is used for adjusting the voltages of a plurality of data wires to be preset voltage, so that the electric charge quantity stored by a polar inversed pixel is the same as that stored by the non-polar inversed pixel for the same-gram scale frame. The liquid crystal display can be used for improving the phenomenon that the frame flashes when the image of the liquid crystal display is displayed and has a better display effect.

Description

technical field [0001] The invention relates to a liquid crystal display. Background technique [0002] The liquid crystal molecules of the liquid crystal display have such a characteristic: if the direction of the electric field loaded on both ends of the liquid crystal layer remains unchanged for a long time, the characteristics of the liquid crystal molecules will be destroyed, that is, they can no longer rotate in response to changes in the electric field to form different shapes. grayscale. Therefore, the liquid crystal display must change the direction of the electric field at regular intervals to invert the liquid crystal molecules, so as to avoid damage to the characteristics of the liquid crystal molecules. Currently common inversion driving methods include: frame inversion driving (Frame Inversion), column inversion driving (Column Inversion), row inversion driving (Line / Row Inversion), and dot inversion driving (Dot Inversion). Among them, dot inversion driving ...
