WIPO Patent Application WO/2020/258879
Kind Code:
A1
Abstract:
A display apparatus, comprising: a substrate (10) and a plurality of light-emitting units (20), arranged on the substrate (10), with different colors of emitting light; an angle-of-view measurement module (30) configured to measure a viewing angle of human eyes; a brightness measurement module (40) configured to measure a plurality of pieces of light brightness data corresponding to light, emitted by each light-emitting unit (20), in a plurality of light emergent angles; and a driving module (50) configured to acquire the viewing angle and the plurality of pieces of light brightness data corresponding to each light-emitting unit (20), to determine, according to the viewing angle and the plurality of pieces of light brightness data corresponding to each light-emitting unit (20), an actual brightness of the light, under the viewing angle, emitted by each light-emitting unit (20), to compare the actual brightness with a target brightness of light, under the viewing angle, having the same color as the light emitted by each light-emitting unit, and to determine a compensation driving signal of each light-emitting unit (20) according to a comparison result.
