Abstract

The invention relates to a liquid crystal display driving device. The liquid crystal display driving device comprises a scan driving unit, a data driving unit, a grid line, a data line and a pixel region which is formed by the grid line and the data line, wherein the grid line comprises a grid scanning line and a redundant grid line; the data line comprises a data signal wire and a redundant data line; and the liquid crystal display driving device also comprises a compensating circuit which is connected with the grid line for compensating a grid scanning signal on the grid scanning line to improve voltage delay phenomenon on the grid scanning line. The liquid crystal display driving device provided by the invention can compensate the grid scanning signal through the compensating circuit which is connected with the grid line, so that the influence of overtime of resistance-capacitance (RC) on the rise time and/or the fall time of the grid scanning signal can be reduced, the charging time requirement of a pixel can be fully met, and the charging rate of the pixel is ensured.

Description

technical field [0001] The invention relates to driving of liquid crystal display, in particular to a driving device of liquid crystal display, which belongs to the field of driving of liquid crystal display. Background technique [0002] At present, the thin film transistor liquid crystal display (TFT-LCD) has become the most important type of display in the display, and the development direction of the TFT-LCD is even more towards the direction of large size and high resolution. However, as the size of the TFT-LCD increases, the gate scanning lines and data signal lines in the TFT-LCD will become longer, which will inevitably lead to an increasing resistance of the gate scanning lines and data signal lines; The higher the resolution, the more overlapping areas between the gate scanning lines and the data signal lines, which will increase the parasitic capacitance of each signal line. [0003] figure 1 It is a structural schematic diagram of an existing TFT liquid crystal...
