Liquid crystal display panel

Abstract

A liquid crystal display. The liquid crystal display having a power device, a display unit array, a scan driver, a selection device, and a current limiting device. In normal operation of the liquid crystal display, according to the operation of the selection device, a voltage signal applied from the power device is directly applied to the scan driver according to the selection device, and the scan driver sequentially outputs scan signals to scan electrodes. During shutdown and power on processes of the liquid crystal display, according to the operation of the selection device, the voltage signal applied from the power device is applied to the scan driver through the current limiting device, limiting the instantaneous current from the power device. Moreover, the scan driver simultaneously outputs all the scan signals to erase charges within all the display units.

Description

technical field [0001] The present invention relates to a flat display, in particular to a liquid crystal display panel, which is suitable for reducing the instantaneous current borne by the scanning driver when the liquid crystal display panel is closed and opened. Background technique [0002] figure 1 is a structural diagram showing a conventional liquid crystal display panel system. A conventional liquid crystal display panel includes a display unit array 10 , a scan driver 11 , a data driver 12 and a power supply device 13 . The display unit array 10 is composed of a plurality of interlaced scan electrodes and data electrodes D1 1 to D1 n Composed of, and each staggered scan electrode G1 1 to G1 m and the data electrode correspond to a display unit. The power supply device 13 provides a voltage signal V13 to the scan driver 11 . When the liquid crystal display panel is in normal operation, the scan driver 11 sequentially outputs the voltage signal V13 to the scan...

Problems solved by technology

[0005] However, since the scan driver 11 simultaneously outputs all scan signals to the scan electrodes G1 when the shutdown and startup procedures are executed. 1 to G1 m , causing the output energy of the power supply device 13 to be concentrated, and the scan driver 11 cannot sequentially output scan signals to the scan electrodes G1 as in normal operation. 1 to G1 m , and disperse the energy

Therefore, when the scan driver 11 simultaneously outputs all the scan signals to the scan electrode G1 1 to G1 m When the scanning signal is transmitted, the bonding area (Vgh bonding area) cannot bear the high energy from the power supply device 13

After several times of closing and opening procedures, the metal in the wiring area is perforated, which affects the general operation of the driver 11
