Liquid crystal panel and control method thereof

Abstract

The invention discloses a liquid crystal panel. The liquid crystal panel comprises a system main board, an enablement driver, a testing signal panel, a switch protection unit, and a system driving circuit. The switch protection unit comprises a plurality of switch units, the control ends of which are connected with the enablement driver. The enablement driver is used to send enablement signals to control the on / off states of the switch units at the same time. In the testing mode of the liquid crystal panel, the switch protection unit is connected, and the testing signal panel is used to send testing signals to test a single pixel electrode. In the normal display mode of the liquid crystal panel, the switch protection unit is disconnected, and then static generated in environment is prevented from entering the line of the system driving circuit through the testing signal panel. The environmental static is prevented from entering the system driving circuit to affect the normal display of the liquid crystal panel, and when an static impedor is damaged, the short circuit of the system main board and the testing signal panel is prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel and a control method thereof. Background technique [0002] Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) has been developed rapidly and widely used in recent years. It is widely used in display devices of portable mobile electronic products, such as mobile phones, digital cameras, handheld computers, GPRS, etc. mobile products. A liquid crystal display panel is generally formed by pairing a color filter substrate and an array substrate, and a liquid crystal layer is encapsulated in the space between the two substrates. The array substrate mainly includes scanning lines, data lines and pixel electrodes. The scanning lines and the data lines are arranged perpendicular to the direction in which the pixel electrodes are formed in the pixel area where the scanning lines and data lines are interlaced. The scanning driving lines are controlled by...
