Abstract

An image display system comprises a liquid crystal display. The liquid crystal display comprises a plurality of gate lines, a plurality of data lines, a plurality of switches, a plurality of storage units, a power cord and a plurality of coupling capacitors. The plurality of data lines and the plurality of gate lines are vertically interlaced with each other. A first end of each switch is coupled with a corresponding gate line, and a second end of each switch is coupled with a corresponding data line. Each storage unit is coupled with a third end of a corresponding switch for receiving the data transmitted from a corresponding data line. The power cord is parallel to the plurality of gate lines. A first end of each coupling capacitor is coupled with the power cord, and a second end of each coupling capacitor is coupled with a corresponding data line.

Description

technical field [0001] The present invention relates to a liquid crystal display system and a related driving method, in particular to a liquid crystal display system and a related driving method for improving display quality by means of power lines and coupling capacitors. Background technique [0002] Liquid Crystal Displays (Liquid Crystal Displays, LCDs) have the advantages of light and thin appearance and low power consumption, so they are widely used in Personal Digital Assistants (Personal Digital Assistants, PDAs), mobile phones, notebook / desktop computers, and communication Panels and other electronic products. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of an active thin-film transistor (Thin-Film Transistor, TFT) liquid crystal display 10 in the prior art. The liquid crystal display 10 includes a source drive circuit 12, a gate drive circuit 14, a plurality of data lines, gate lines Gate 1 -Gate m , demultiplexer DUX 1 -DUX n , an...
