Title:
IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/027107
Kind Code:
A1
Abstract:
An image display device according to an embodiment of the invention is provided with a plurality of pixel circuits in which a first power supply line to which a direct-current voltage is applied and a second power supply line which is set to a lower potential than the first power supply line are arrayed in matrix form. Each of the plurality of pixel circuits includes a light-emitting element, and a first circuit connected to the light-emitting element, which sets, on the basis of the result of comparison of a first signal including a triangular-wave signal with a first direct-current voltage set in a prescribed period, a time width in which a current is supplied to the light-emitting element. At least some of the plurality of pixel circuits are connected to the first circuit in series, and include a second circuit for controlling the current value supplied to the first circuit on the basis of a second direct-current voltage that is set in a period different from the prescribed period.
