Title:
LED DISPLAY DEVICE AND DISPLAY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/234618
Kind Code:
A1
Abstract:
In the present invention, a display unit has LED elements (10) arranged two-dimensionally, and displays a video by causing the LED elements (10) to sequentially emit light. A light incidence discrimination unit detects a photocurrent flowing through the LED element (10) and discriminates an incident light intensity of the LED element (10). A display control unit sets the luminance value of the LED element (10) on the basis of a result of discriminating the incident light intensity by the light incidence discrimination unit. The display driving unit drives the LED element (10) by controlling the current value of a current driver (13) so that the LED element (10) has the luminance value set by the display control unit.
