摘要:
A driving circuit of an active matrix method in a display device is disclosed, which can compensate luminance deviation of the display device according to threshold voltage deviation of a driving unit. The driving circuit of the active matrix method includes a switching unit switching a current applied from the driving unit to the display device, and a deviation compensator detecting the current applied to the display device by switching of a second switch, and controlling a control voltage, thereby compensating luminance deviation of the display device according to threshold voltage deviation of the driving unit.

A voltage adder includes a first amplifier, a feedback resistor, and a control current source. The first amplifier includes a first input terminal to which a first voltage is input, a second input terminal connected to a feedback node, and an output terminal connected to an output node. The feedback resistor is connected between the output node and the feedback node. The control current source allows an addition current corresponding to a second voltage to flow through the feedback resistor.
摘要:
An output of a driving circuit is controlled by selectively outputting a first voltage or a second voltage as an N-th output voltage level in response to a first control signal and an N-th input voltage level, where N is a natural number, and pre-charging the selected N-th output voltage level to a third voltage or a fourth voltage, in response to a second control signal, the pre-charging being preformed based on the selected N-th output voltage level and a newly input (N+1)th input voltage level.
