Title:
STRETCHABLE DISPLAY DEVICE COMPENSATION CIRCUIT AND STRETCHABLE DISPLAY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/014931
Kind Code:
A1
Abstract:
A stretchable display device compensation circuit presented in the present invention comprises a light-emitting element, and uses a strain sensor so as to control current flowing into the light-emitting element, and thus a change in luminance during stretching of the display device can be compensated for.
