Abstract
(EN)
The present disclosure is related to a light emitting diode. The light emitting diode may include a pixel unit. The pixel unit may include a first sub-pixel configured to emit white light. The first sub-pixel may include a first microcavity adjustment layer, a scattering layer, a first transparent electrode layer, a first emitting layer, and a first semi-transparent electrode layer. The scattering layer may be configured to reduce color cast of the first sub-pixel to be less than about 0.025 at viewing angles in a range of about -50 degree to +50 degree.

La présente invention porte sur une diode électroluminescente. La diode électroluminescente peut comprendre une unité de pixel. L'unité de pixel peut comprendre un premier sous-pixel configuré pour émettre une lumière blanche. Le premier sous-pixel peut comprendre une première couche de réglage de microcavité, une couche de dispersion, une première couche d'électrode transparente, une première couche d'émission, et une première couche d'électrode semi-transparente. La couche de dispersion peut être configurée pour réduire la dominante de couleur du premier sous-pixel de façon à être inférieure à environ 0,025 à des angles de vision dans une plage d'environ -50 degrés à +50 degrés.
