Abstract

The invention relates to a TFT-LCD array base plate and a drive method thereof. The array base plate comprises a base plate, wherein the base pate is provided with pixel areas which are ranged in a matrix way; each pixel area is provided with a first pixel electrode, a first film transistor, a second pixel electrode and a second film transistor, the first pixel electrode and the first film transistor are positioned in an odd line, and the second pixel electrode and the second film transistor are positioned in an even line; a first grid line and a second grid line are arranged in each pixel area, the first grid line is connected with a grid electrode of the first film transistor, and the second grid line is connected with a grid electrode of the second film transistor; and a data line is arranged in each pixel area and respectively connected with a source electrode of the first film transistor and a source electrode of the second film transistor. The invention reduces the quantity of the data lines and data drive chips or pins thereof or reduces the quantity of the grid lines and scanning drive chips or pins thereof and lowers the production cost of a TFT-LCD.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof, in particular to a TFT-LCD array substrate and a driving method thereof. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) mainly includes: a liquid crystal display panel, a scanning drive circuit and a data drive circuit; wherein, the liquid crystal display panel includes a color film substrate and an array substrate arranged in a box, and a set The liquid crystal layer between the two substrates; the scan driving circuit and the data driving circuit are respectively connected with the TFT switching elements on the array substrate. [0003] In a traditional TFT-LCD array substrate, a TFT switch element is controlled by a data line (DataLine) and a gate line (Gate Line), and the pixel electrode connected to the TFT switch element is driven by turning on or off the TFT switch element. When the array substrate is working, th...
