Disclosed is a display driver which includes a serial-to-parallel converter outputting parallel RGB data in response to a clock and serial RGB data, a shift register unit sequentially shift the clock to store the shifted clocks, a data latch unit receiving the parallel RGB data based on the shifted clocks, a digital-to-analog converter converting data stored in the data latch unit to analog data using gamma reference voltages, and an output buffer unit outputting the converted analog data to corresponding output pads. The output buffer unit includes sharing switches respectively corresponding to the output pads, the output pads are connected to sharing pads via the sharing switches, and the sharing pads are interconnected via a film having a conductive material.

Display driver and manufacturing method thereof

A power supply system includes a control unit comprising a detecting and converting unit that is operable to generate a detected current based on a difference between a set voltage and a voltage representative of a current flow through an energy storage member.

Power supply and display apparatus having the same

Source drivers and display devices that include such source drivers are provided that may be used to control the amount of output current from an output buffer. These source drivers may comprise a buffer that is configured to receive an input signal and a control circuit that is coupled to the buffer that is configured to control an output current level of the buffer. The control circuit may comprise a bias voltage generator that is configured to generate a plurality of bias voltages, and the output current level of the buffer may be controlled based on the plurality of bias voltages. Methods of controlling the amount of current output from an output buffer of the source driver and methods of driving a display device are also provided.
