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.

摘要: The present invention relates to an output voltage stabilization circuit. Specifically, the present invention relates to an output voltage stabilization circuit of a display device driving circuit, which generates a reference current dependent on a high source voltage using a current source independent of a magnitude of the high source voltage, generates a reference current dependent on a low source voltage using a current source independent of a magnitude of the low source voltage, and then generates a control signal by comparing the magnitudes to each other, whereby the output voltage stabilization circuit may stabilize an output voltage regardless of an order in which the low source voltage and the high source voltage are turned off in a circuit using both the low source voltage and the high source voltage.
