Title:
PANEL DRIVING DEVICE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/206630
Kind Code:
A1
Abstract:
A panel driving device and a display device. The panel driving device comprises an interface module (11), a voltage conversion module (12), and a compensation module (13). The interface module (11) comprises a first input end and a first output end. The voltage conversion module (12) comprises a second input end and a second output end. The first output end is coupled to the second input end. The voltage at the first input end is a first voltage signal (V1), the voltage at the first output end is a second voltage signal (V2), the voltage at the second input end is a third voltage signal (V3), and the voltage at the second output end is a fourth voltage signal (V4). The compensation module (13) is configured to generate a compensation voltage signal according to the third voltage signal (V3) and apply the compensation voltage signal to the first input end or the first output end so that the third voltage signal (V3) is equal to the first voltage signal (V1). The panel driving device and the display device can compensate for the cable transmission loss and the wiring loss of a printed circuit board, thereby avoiding the work anomaly of a liquid crystal panel.
