Problems solved by technology

But none of these options are ideal
There is also a technical solution using a unified light scattering layer in the technology, but the extraction effect of some light bands in this solution is not obvious
In the prior art, there is also a technical solution of using different optical resonant layers for R / G / B sub-pixels, but this technical solution is very difficult in process, high in cost, and difficult to realize commercial use.

Abstract

The invention discloses an OLED device with an optical resonance layer, a manufacturing method of the OLED device and a displayer. The OLED device comprises a white light OLED and a color filter film, the white light OLED and the color filter film are used for forming R sub-pixels, G sub-pixels, B sub-pixels and W sub-pixels, and the optical resonance layer is at least arranged between the white light OLED and the color filter film and corresponds the area of the G sub-pixels. According to the OLED device with the optical resonance layer, the optical resonance layer is arranged, so even if the color filter film low in color gamut is adopted, monochromatic light good in chroma and high in efficiency can be filtered out, and especially, the problem that display quality is low in the current white light OLED+CF technology is solved. In addition, the OLED device greatly reduces power consumption. No fine metal mask (FMM) is needed, so that process cost is reduced.

Description

technical field [0001] The invention relates to the field of OLED display technology, in particular to an OLED device with an optical resonant layer, a preparation method thereof, and a display including the OLED device. Background technique [0002] With the progress of science and technology, liquid crystal display (Liquid Crystal Display, LCD) has gradually replaced the traditional bulky cathode ray display (Cathode Ray Tube, CRT) because of its advantages of small size and light weight, and has been widely used Used in monitors, notebook computers, flat-panel TVs, digital cameras and other electronic products. [0003] The LCD requires a light emitting diode (Light Emitting Diode, LED) as a backlight source. Organic Light Emitting Diode (OLED) displays do not require a backlight module, are more suitable for thin displays, and have the advantage of no viewing angle restrictions, so they tend to replace traditional CRTs and LCDs. [0004] OLED displays include RGB displ...
