Abstract: A light emitting display device includes a display panel, a power supply configured to supply a first potential voltage and a second potential voltage to the display panel, and a switch circuit unit configured to sense the first potential voltage applied to the display panel and to feedback the first potential voltage to the power supply, wherein the power supply compensates for the first potential voltage based on the first potential voltage fed back from the switch circuit unit and to output the compensated first potential voltage.

Abstract: Disclosed herein are a display device capable of reducing the number of transmission lines by enabling a master circuit to perform communication with a plurality of slave circuits, which utilize different interfaces, through a common transmission line in a time divisional manner, and an interface method thereof. A timing controller uses a common transmission line of a gamma voltage generator and a level shifter which respectively utilize first and second interfaces and perform communication using the first and second interfaces in a time divisional manner.

Abstract: Disclosed are a chip on film (COF) and a display device including the same, for reducing the number of input pads using a pattern branching structure. The COF is connected to gate-in-panel (GIP) output pads using a structure formed via branching of GIP wirings connected to the GIP input pads in a data driving integrated circuit (IC) or a circuit film to reduce the number of GIP input pads.
