Panel drive device and display device

Abstract

Embodiments of the present disclosure provides a panel drive device and a display device. The panel drive device includes an interface module, a voltage conversion module and a compensation module. The interface module includes a first input end and a first output end. The voltage conversion module includes a second input end and a second output end. The first output end is coupled with the second input end. A voltage at the first input end is a first voltage, a voltage at the first output end is a second voltage, a voltage at the second input end is a third voltage signal and a voltage at the second output end is a fourth voltage signal. The compensation module is configured to generate a compensation voltage signal according to the third voltage signal and apply the compensation voltage signal to the first input end or the first output end, so that the third voltage signal equals to the first voltage signal. The panel drive device and the display device according to embodiments of the present disclosure are able to compensate for the losses in the transmission cables as well as in the wires of the printed circuit board, thereby avoiding abnormal operations of the liquid crystal panel.
