Embodiment Construction

[0036] figure 2 It is a block diagram of an internal circuit of a display device according to an embodiment of the present invention. Please refer to figure 2 , the display device provided by the present invention includes a display panel 210 . In the display panel 210 , scan lines G1 ˜ Gm and data lines D1 ˜ Dn are provided. Wherein, the scan lines G1-Gm are arranged parallel to each other along the first direction, and the data lines D1-Dn are arranged parallel to each other along the second direction and interlaced with the scan lines G1-Gm. In general, the first direction is substantially perpendicular to the second direction. At the intersection of each scan line and data line, pixel units such as 212 are provided. In the present invention, a switch circuit such as 214 is provided on each scanning line. Each switch circuit determines whether to conduct the common voltage Vcom to the pixel units on the corresponding scanning line according to the scanning signal tra...

Abstract

A display panel with number of data line and scan line, wherein scan line parallel arrangement along first direction, and data line parallel each other along second direction and interlacing configuration with scan line, on each scan line and data line intersection area set with pixel unit, and each scan line set with switching element, each switching element according to corresponded scan line transmitted scanning signal determining whether conducting public voltage to corresponded scan line coupled pixel unit. The present invention can effectively relieve public voltage load.

Description

technical field [0001] The invention relates to a display panel, and in particular to a display panel capable of reducing the load of a common voltage. Background technique [0002] For the rapid progress of the multimedia society, most of them benefit from the rapid progress of semiconductor devices or display devices. As far as the display is concerned, the cathode ray tube (Cathode Ray Tube, CRT) has been monopolizing the display market in recent years because of its excellent display quality and economical efficiency. However, for the environment where individuals operate most terminals / display devices on the table, or from the perspective of environmental protection, if the trend of energy saving is predicted, cathode ray tubes still have many problems in terms of space utilization and energy consumption, and There is no effective solution to the demands of lightness, thinness, shortness, smallness and low power consumption. Therefore, thin film transistor liquid crys...
