摘要： Disclosed are an offset compensation gamma buffer and a gray scale voltage generation circuit using the same. The offset compensation gamma buffer includes: a buffer which outputs an input voltage input to a positive or negative input terminal as an output voltage; and a switching unit which selectively connects the input voltage and the output voltage of the buffer to the positive and negative input terminals in response to a control signal. The output voltage of the offset compensation gamma buffer is supplied to the input of a gray scale voltage generation circuit of a source driver for driving a liquid crystal panel. The offset of the offset compensation gamma buffer is compensated using an inversion timing of the control signal. The output voltage of the offset compensation gamma buffer is supplied as a reference voltage of the voltage divider unit for generating the gray scale voltages, and the offset of the gray scale voltages is also compensated.

摘要： An output driver of an electronic paper display device includes M number of output driver sections configured to transmit M number of pieces of data, respectively, to the electronic paper display device, wherein the M number of output driver sections are divided into a plurality of groups, and are temporally dispersed and driven according to groups, thereby transmitting the M number of pieces of data to the electronic paper display device. Also, an output driver for transmitting data to an electronic paper display device includes N number of drivers, wherein a part of the N number of drivers are selected and driven according to an output impedance of the electronic paper display device. Since output driver sections are divided into groups and are dispersedly driven, peak current is reduced. Since drivers are selectively driven according to the sizes of output loads, a constant driving capability is provided.
