Abstract

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.

Description

technical field [0001] The present invention relates to an OLED (Organic Light-Emitting Diode, organic light-emitting diode) structure. Background technique [0002] OLED is a self-luminous display technology. The luminous efficiency of OLED is related to the design of selected luminescent materials, backplane and peripheral components. OLEDs must be reflected by means of a reflective layer to increase luminous brightness, thereby improving related display performance. [0003] For the OLED light-emitting structure in the prior art, see figure 1 shown. The anode in the OLED light-emitting structure has a reflective layer for reflecting light generated by the organic light-emitting layer. The reflective layer can be an anode metal plane. The light generated by the OLED light-emitting structure is as follows figure 1 As shown, the light emitted by it is randomly scattered. Some light is not emitted from the effective light-emitting area and direction, resulting in low ov...
