Abstract:
1. A driver circuit for driving an active-matrix display panel, comprising: a current Digital-to-Analog Converter (CDAC) for generating driving current corresponding to input digital data; a data line providing said driving current to an array of pixel prepared on the display panel; an adjacent data line providing a similar or equivalent resistive and capacitive load of said data line; two driving transistors M two current source, wherein the one current source is connected to the source of the transistor M a current mirror for feeding back transient charging current is generated by the parasitic capacitance of the adjacent data line, as current for charging the data line; a voltage source VDD connected to the sources of transistor of said current mirror; a differential amplifier whose output is connected to the gates of the transistor M a constant voltage V a node A a node A
