Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] In order to prevent bad experience caused by reflected light on the screen, OLED displays usually add a layer of polarizer on the OLED encapsulation layer to control the polarization direction of the outgoing beam. At present, the existing COE (color film on encapsulation, that is, the color film is directly made on the encapsulation layer) technology directly prepares a light shielding layer on the encapsulation layer to reduce reflected light....

Abstract

The embodiment of the invention provides a display panel and a display device, and solves the problem that the light emitting efficiency of a light emitting device is reduced due to emergent light loss caused by low transmittance of a polarized light sheet. The display panel provided by the embodiment of the invention comprises a back plate, a light emitting layer, a packaging layer and a light condensing layer which are sequentially stacked; the light-emitting layer comprises a plurality of light-emitting units, the light-condensing layer comprises a plurality of light-condensing units, and the plurality of light-condensing units and the plurality of light-emitting units are in one-to-one correspondence in the light-emitting direction of the light-emitting layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the popularization of OLED (Organic Electroluminescence Display, organic light-emitting semiconductor) devices, the requirements for power consumption of OLED devices are becoming more and more stringent. The main power consumption of OLED display products is the light-emitting layer power consumption. The higher the luminous efficiency of the light-emitting layer, the lower the power consumption of OLED display products. Therefore, improving the luminous efficiency of OLED display devices is the main method to reduce power consumption. [0003] At present, in order to prevent the bad experience caused by the reflected light on the screen, most OLED displays usually add a layer of polarizer on the OLED packaging layer to control the polarization direction of the outgoing beam, but the transmittance ...
