Document Type and Number:
WIPO Patent Application WO/2023/218922
Kind Code:
A1
Abstract:
The present disclosure relates to a display system and an operation method for the display system that, when realizing a power source device for a high luminance direct-view LED (light-emitting diode) display by a plurality of ordinary luminance power source devices, make it possible to continue display even when any one of these breaks down. A driver group for driving the light-emitting diodes (LEDs) arranged in array form on the basis of a video signal is provided with a plurality of ordinary luminance power sources that supply the electric power needed for drive in an ordinary luminance mode and a power supply switch that switches power supply from the plurality of ordinary luminance power sources to the driver group on or off. When abnormality in the power sources is detected, the power supply switch is turned off and the LEDs are driven by being switched from a high luminance mode to the ordinary luminance mode and then the power supply switch is turned on. The present disclosure is applicable to LED display devices.
