Abstract:
1. A liquid crystal display (LCD) driving device, comprising: a scanning driving unit; a data driving unit; gate lines; data lines; pixel regions defined by the gate lines and the data lines; and a compensation circuit connected to the gate lines, wherein the gate lines include gate scanning lines and a redundant gate line, the data lines includes data signal lines and a redundant data line, the compensation circuit is used to compensate gate scanning signals of the gate scanning lines, so as to reduce voltage delay over the gate scanning lines, wherein the compensation circuit comprises a compensation signal line and first thin film transistors that correspond to the respective gate scanning lines, wherein a source electrode and a drain electrode of each of the first thin film transistors are directly connected to, respectively, the corresponding gate scanning line and the compensation signal line, and a gate electrode of said each of the first thin film transistors is connected to an end of the previous gate scanning line immediately prior to the corresponding gate scanning line, and wherein the redundant gate line is regarded as the previous gate scanning line immediately prior to a first gate scanning line, wherein the compensation circuit further comprises:
