Abstract:
A display device, comprising:an array of display cells;a data line electrically coupled to at least one display cell in said array thereof;a decoder that outputs a first data line signal having a magnitude equal to a first gray level voltage during a first selection time interval, in response to a data input signal;a data line driver circuit that drives said data line with buffered and unbuffered versions of the first data line signal during first and second consecutive portions of the first selection time interval, respectively, said data line driver circuit comprising:a follower amplifier having an input electrically coupled to an output of said decoder and an output electrically coupled to said data line; anda transmission gate having an input electrically coupled to the output of said decoder and an output electrically coupled to said data line; anda buffer control circuit that is electrically coupled to said follower amplifier and said transmission gate and generates a control signal having a first state that enables said follower amplifier and disables said transmission gate during the first portion of the selection time interval and a second state that disables said follower amplifier and enables said transmission gate during the second portion of the selection time interval.
