Title:
表示装置およびその駆動方法
Document Type and Number:
Japanese Patent JP7470797
Kind Code:
B2
Abstract:
A display device includes: a plurality of scanning lines; a plurality of data lines; a plurality of light-emission control lines; a plurality of pixel circuits each including a light-emitting element; a scanning line drive circuit that drives the scanning lines based on a first clock signal; a data line drive circuit that drives the data lines; a light-emission control line drive circuit that drives the light-emission control lines based on a second clock signal; and a display control circuit that outputs at least the first and second clock signals. The display control circuit classifies a frame period into a scanning period and a pause period, and during the pause period, the display control circuit stops the first clock signal and makes a frequency of the second clock signal lower than that during the scanning period. This further reduces the power consumption of the display device that performs low-frequency driving.
