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 present invention provides a microcavity OLED device, which includes a glass substrate and a plurality of pixels vertically distributed on the glass substrate, each of the pixels includes a plurality of sub-pixel microcavities, and each sub-pixel microcavity is The transverse cross-section has an arc-shaped structure that can make the path of the excited light in the sub-pixel microcavity at least partially consistent. In this way, the path of the excited light in the microcavity is the same, and the resulting resonance spectrum is also consistent, and there is no chromatic aberration or very small chromatic aberration from all angles, so that the problem of chromatic aberration 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, and viewing angle Wide, fast response, high luminous efficiency, no need for backlighting, and flexible display, etc., have important applications in the field of display and lighting, especially as the display device with the most potential 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 OLED is fabricated o...
