OUTPUT BUFFER HAVING HIGH SLEW RATE, METHOD FOR CONTROLLING TNE OUTPUT BUFFER, AND DISPLAY DRIVE IC USING THE SAME

摘要

PURPOSE: An output buffer having high slew rate, a method for controlling the output buffer, and a display drive IC using the same are provided to reduce heat from a chip by suppressing heat from an output transmission gate. CONSTITUTION: A first output buffer is driven between a first voltage rail and a second voltage rail. The first output buffer outputs a source line driving signal to the first output terminal(Vouth 1) in response to the first control signal. A second output buffer is driven between a third voltage rail and a fourth voltage rail. A second output buffer outputs the source line driving signal to a third output terminal(Vouth 2) in response to the first control signal. A feedback circuit connects the output terminals and a negative input terminal in response to the first control signal and the second control signal.
