Liquid crystal display panel and its array substrate circuit

Abstract

The invention discloses an array substrate circuit of a liquid crystal display panel. The array substrate circuit comprises at least one first source electrode drive chip arranged at the upper side of the array substrate circuit and at least one second source electrode drive chip arranged at the lower side of the array substrate circuit. All adjacent first pins of the first source electrode drive chip are different in polarity of output signals, all adjacent second pins of the second source electrode drive chip are different in polarity of output signals, data lines are connected in the mode that every two columns of first pins and every two columns of second pins are arrayed alternately so that one source electrode drive signal can be input into a pixel; signals output by the adjacent data lines are different in polarity, and the multiple pixels adjacent vertically and horizontally are different in polarity, so that dot inversion of the pixel polarity is achieved in a column inversion mode without changing the signal output mode of an existing source electrode drive chip, and frame flicker is reduced.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display panel and an array substrate circuit thereof, in particular to a liquid crystal display panel and an array substrate circuit thereof which realize pixel point inversion by arranging source drive chips on the upper and lower sides and column inversion. 【Background technique】 [0002] A liquid crystal display panel (LCD panel) is a layer of liquid crystal sandwiched between two glass substrates. The upper glass is a color filter (CF) substrate, and the lower glass is an array (Array) embedded with thin-film transistors (TFT). substrate, and the upper CF substrate forms a color resistance corresponding to the position of the thin film transistor, wherein each pixel (Pixel) of the panel is composed of three sub-pixels (Sub Pixel) of red, blue and green. When the current passes through the thin film transistor, the electric field changes, causing the deflection of the liquid crystal molecules, which can de...

Problems solved by technology

Therefore, such a design scheme still cannot make the polarities of the signals of each adjacent data line different, and therefore cannot make the polarities of each adjacent pixel up and down and left and right different.

That is to say, unless the signal output mode of the first source driver chip 204 and the second source driver chip 205 is changed in the existing array substrate circuit 200, the pixel cannot be implemented in a column inversion manner. The point of polarity is reversed, so the flickering of the screen cannot be reduced
