(EN) Organic lighting structure
(ZH) 一种有机发光结构
Abstract
(EN)
The invention discloses an organic lighting structure comprising an anode layer and a cathode layer, and an organic lighting layer arranged between the anode layer and the cathode layer; the organic lighting structure also comprises a side face reflection layer; the anode layer has a reflection layer, and the cathode layer is a transparent structure; the side face reflection layer is arranged under the cathode layer so as to form a light emitting zone with the anode layer; the anode layer and the side face reflection layer reflect the light emitted by the organic lighting layer, so the light can be emitted from the lighting emitting zone. The side face reflection layer is arranged around the organic lighting layer so as to reflect the light of side directions, thus improving light emitting efficiency of the organic lighting structure having very high application value.
