Problems solved by technology

The main reason is: the above-mentioned circuit is relatively complicated, and each power supply is connected in parallel with a large number of filter capacitors, resulting in slow charge discharge, and it takes a long time for charge discharge. Therefore, there is a shutdown screen due to the failure of the power supply charge to be released in time Display abnormal phenomenon

Abstract

The invention discloses a power source discharging speed accelerating device, which comprises a liquid crystal panel, an integrated source drive circuit, an integrated grid drive circuit, a voltage adjusting circuit and a switch circuit, wherein, the voltage adjusting circuit has a power source input end, an analog power source output end, a grid cut-in voltage output end and a grid turn-off voltage output end, the analog power source output end is connected with the integrated source drive circuit, the grid cut-in voltage output end and the grid turn-off voltage output end are connected withthe integrated grid drive circuit; the switch circuit is arranged in at least one output end and used for importing electric charge of a power source directly into ground when turning off the power source, thus raising the discharging speed of the power source. Through the technical proposal that the electric charge of the power source is released in time when turning off machines, the power source discharging speed accelerating device eliminates abnormal picture phenomenon and improves picture quality.

Description

technical field [0001] The invention relates to a device for accelerating the discharge speed of a power supply, in particular to a device for accelerating the discharge speed of a power supply by utilizing the characteristics of the field effect tube itself. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has the characteristics of light weight, flat panel, low power consumption, no radiation, and excellent display quality, and the existence of these advantages must depend on a good circuit. Among them, the main part of the driving circuit consists of multiple It consists of a circuit voltage source, a circuit that can give correct digital logic signals, and a backlight drive circuit designed to see the display screen. Of course, different LCD displays require some different peripheral auxiliary circuits due to differences in internal circuits. [0003] For the multi-channel voltage generation circuit, since the digital circuit and the an...
