a liquid crystal display

Abstract

The invention discloses a liquid crystal display achieving dot inversion. The liquid crystal display comprises n gate lines and m data lines. The n gate lines are used for transmitting gate electrode drive signals. The m data lines are used for transmitting data drive signals. A plurality of pixel units are defined by the n gate lines and the m data lines and form a pixel matrix. According to the pixel matrix, for the pixel units of the same row, the gate electrodes of TFTs of pixels in the columns of the odd number are connected with the same gate line, and the gate electrodes of TFTs of pixels in the columns of the even number are connected with the same gate line; for the pixel units of the same column, the source / drain electrodes of TFTs of pixels in the rows of the odd number are connected with the same data line, and the source / drain electrodes of TFTs of pixels in the rows of the even number are connected with the other same data line. The liquid crystal display can achieve dot inversion through either the row inversion drive mode or the column inversion drive mode without changing the pixel connection mode.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a liquid crystal display with point inversion. Background technique [0002] Liquid crystal displays have the advantages of low radiation, small size, and low energy consumption. They have gradually replaced traditional cathode ray displays, and are therefore widely used in information products such as notebook computers, personal digital assistants, flat-screen TVs, or mobile phones. When displaying pictures, in order to prevent the liquid crystal from aging, the LCD usually adopts the polarity inversion mode. The typical polarity inversion modes are: frame inversion (frame inversion), row inversion (rowinversion), column inversion (column inversion) and dot inversion (dotinversion). as attached figure 1 shown. Of the four inversion modes, the dot inversion method produces the best image quality. However, during the polarity conversion process of point inversion, compa...

Problems solved by technology

[0004] However, the method of changing row inversion to dot inversion in the prior art cannot support the driving method of column inversion at the same time; or the method of changing column inversion to dot inversion cannot support row inversion to dot inversion The driving mode of rotation brings great difficulties to the flexibility of the design
