Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a display panel including pixels and data lines and gate lines connected to the pixels;
a timing controller configured to be mounted on a printed circuit board, and outputting an intra-interface signal through an intra-interface;
a source driver configured to be mounted on a conductive film electrically connecting the printed circuit board and the display panel, and generating data driving signal based on source driving bit information included in the intra-interface signal and supplying the data driving signal to the data lines; and
a GIP circuit configured to be formed on the display panel, and generating a gate driving signal according to a gate control signal and supplying the gate driving signal to the gate lines;
a level shifter circuit configured to be mounted on the printed circuit board, and boosting a voltage swing width of a gate control logic signal based on gate driving bit information included in the intra-interface signal and generating the gate control signal and supplying the gate control signal to the GIP circuit;
wherein the intra-interface connects the timing controller to the source driver and the level shifter in parallel, and
wherein the level shifter is connected to the GIP circuit by a signal transmission path passing through the printed circuit board, the conductive film, and the display panel but excluding the source driver.
