Problems solved by technology

However, due to the wide-angle interference in the microcavity effect, the viewing angle characteristics of the device will be affected, that is, as the viewing angle shifts, the luminous peak will shift, resulting in chromatic aberration in the display effect of the OLED device.

Abstract

The invention provides a micro-cavity organic light emitting diode (OLED) device. The micro-cavity OLED device comprises a glass substrate and a plurality of pixels, wherein the plurality of pixels are vertically arranged on the glass substrate, each pixel comprises a plurality of sub-pixel micro-cavities, each sub-pixel micro-cavity is provided with an arc structure on the transverse cross section, and the arc structure can be used for enabling at least one part of paths of simulated light rays passing through the sub-pixel micro-cavity to be consistent. Therefore, the paths of the simulated light rays passing through the micro-cavities are all consistent, the generated resonant spectrums are also consistent, no aberration or small aberration is generated from all angles, and the aberration problem can be improved.

Description

technical field [0001] The invention relates to the field of organic electroluminescence, in particular to a microcavity OLED device. Background technique [0002] Organic Light Emitting Diode (OLED) is a device that uses organic materials as the light-emitting layer under the action of an electric field. It is a new type of active light-emitting display device with light weight, thin thickness, high brightness, wide viewing angle, and responsive It has the advantages of fast speed, high luminous efficiency, no need for backlighting, and flexible display. It has important applications in the field of display and lighting, and has become the most potential display device to replace liquid crystal displays. According to the light-emitting position of the device, it can be divided into bottom emitting OLED (Bottom Emitting OLED, referred to as BEOLED) and top emitting OLED (TopEmitting OLED, referred to as TEOLED). [0003] The structure of the bottom-emitting OLED is that the...
