Abstract

The embodiment of the invention provides a display driving circuit, a driving method thereof and a display device, relates to the technical field of display, and is capable of solving the problem of a lowered display effect caused by an increased TFT leakage current of the display driving circuit. The display driving circuit comprises a grid driving unit, a boost unit, a compensation unit, a waveform generation unit and a monitoring unit. The monitoring unit is connected with the boost unit. The boost unit is further connected with an analog voltage source, the waveform generation unit, the grid driving unit and the compensation unit. The compensation unit is further connected with the analog voltage source, the waveform generation unit and the grid driving unit. The waveform generation unit is further connected with the grid driving unit. The display driving circuit is used for driving the displaying of a display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display driving circuit, a driving method thereof, and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display), as a flat panel display device, has become more and more popular due to its small size, low power consumption, no radiation and relatively low production cost. It is widely used in the field of high-performance display. When the TFT-LCD is displaying, the gate lines of each row on the display panel are scanned row by row to turn on the pixel unit connected to the row of gate lines, and the data line outputs the data signal to the turned-on pixel unit, and the pixel unit is turned on. Charge. The deflection angles of the liquid crystals corresponding to the pixel units charged with different electric charges are also different, so that images with different gray scales...
