Abstract: A connector for a display device is capable of visually detecting defects when an FPCB is connected to a PCB in the display device, e.g., a tablet and a smart phone. The connector includes a first gaff-type connection portion disposed at one end portion of a flexible printed circuit board, and a second gaff-type connection portion disposed at one end portion of a printed circuit board and fitted to the first gaff-type connection portion.

Abstract: A gamma voltage generator includes a reference gamma selecting circuit that receives first and second reference voltages and selects an upper reference gamma voltage (e.g., corresponding to a maximum gamma tab voltage among voltages between the first and second reference voltages) and a lower reference gamma voltage (e.g., corresponding to a minimum gamma tab voltage among the voltages) based on a dimming level, a bias control circuit that calculates the minimum gamma tab voltage based on the upper and lower reference gamma voltages and outputs bias control signals when the minimum gamma tab voltage is less than a reference voltage, a gamma tab voltage generating circuit that generates gamma tab voltages between the minimum and maximum gamma tab voltages based on the upper and lower reference gamma voltages, and a gamma output circuit that distributes the gamma tab voltages to output gamma voltages corresponding to a gamma curve.
