Embodiment Construction

[0021] see image 3 , image 3 It is a schematic circuit diagram of a preferred embodiment of the liquid crystal display 100 of the present invention. The liquid crystal display 100 can be a screen of a personal computer or a screen of a notebook computer. The liquid crystal display 100 includes a switch circuit 102 , a timing controller 104 , a data driver 106 , a scan driver 108 and a liquid crystal display panel 110 . When the vertical synchronization signal generated by the timing controller 104 is transmitted to the scan driver 108, the scan driver 108 will generate a scan signal via the scan line G 1 -G n At the same time, the timing controller 104 will send a horizontal synchronization signal to the data driver 106, and the data driver 106 will pass the data line D 1 -D m The gray scale voltage is output to the pixel unit 120 of the liquid crystal display panel 110 . The timing controller 104 also outputs the first switching signal S1, the second switching signal ...

Abstract

An LCD (100) and a drive method thereof are provided. The LCD (100) includes a plurality of data lines (D1-Dm), a data driver (106), a plurality of pixel units (120) and a switch circuit (102) connected between the data driver (106) and the data lines (D1-Dm). The data driver (106) is used for writing gray scale voltage on the data lines (D1-Dm) in a dot invert drive way. The switch circuit (102) includes a plurality of first switches (T1), a plurality of second switches (T2) and a plurality of third switches (T3). By the switch circuit (102) controlling on / off of three groups of switches, before the data lines (D1-Dm) are written with the gray scale voltage, the voltage of the data lines (D1-Dm) is converted to the gray scale voltage to be written in advance. The LCD (100) consumes low power.

Description

technical field [0001] The invention relates to a liquid crystal display and a driving method thereof. Background technique [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products. Liquid crystal displays have gradually become widely used in various electronic devices such as televisions, mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. A monitor with a high-resolution color screen. [0003] see figure 1 , figure 1 It is a schematic circuit diagram of a liquid crystal display 10 in the prior art. The liquid crystal display 10 includes a timing controller 14 , a data driver (source driver) 16 , a scan driver (gate driver) 18 and a liquid crystal display panel 20 . When the frequency signal pulse generated by the timing controller 14 is sent to the scan driver 18, the scan driver 18 will generate a scan signal to the liquid crystal display...
