Method for adjusting color saturation of silicon-based white light OLED

Abstract

The invention discloses a method for adjusting the color saturation of a silicon-based white light OLED. The method specifically comprises the steps of S1, defining the thickness of an organic layer Bbetween an anode and a light-emitting layer as L1, and defining the thickness of an organic layer D between the light-emitting layer and a cathode as L2; S2, randomly determining an initial thicknessvalue of the organic layer D, and determining a thickness value L1 of the organic layer B based on a relational expression between the thickness of the organic layer B and CIE-y; S3, based on the thickness value L1 of the organic layer B, determining a relational expression between the thickness of the organic layer D and CIE-x and CIE-y, enabling CIE-x=CIE-y=0.33, and calculating the thickness L2 of the organic layer D; and S4, adjusting the thickness of the organic layer B and the thickness of the organic layer D based on the thickness value L1 and the thickness value L2 respectively. The CIE of a light source of the WOLED is close to (0.33, 0.33), the color purity of the WOLED is improved, and meanwhile, the influence on the efficiency of the WOLED is small.

Description

technical field [0001] The invention belongs to the technical field of WOLED devices, and more specifically, the invention relates to a method for adjusting the color saturation of a silicon-based white light OLED. Background technique [0002] Compared with the traditional AMOLED display technology, the silicon-based OLED microdisplay is based on a single crystal silicon chip, and with the help of a mature CMOS process, the pixel size is smaller and the integration level is higher. It can be made into a near-eye display comparable to a large-screen display. products have received widespread attention. Based on its technical advantages and broad market, silicon-based OLED microdisplays will set off a new wave of near-eye displays in the military and consumer electronics fields, bringing unprecedented visual experience to users. [0003] Most of the existing silicon-based OLED full-color realization methods use WOLED (white OLED) + CF (color filter) technology, as shown on t...

Problems solved by technology

White light belongs to composite light. Adjusting the organic layer alone to change the optical thickness can only strengthen one of the color changes, and it will have a negative effect of interference and cancellation on the light of the other color, which will eventually lead to the color shift of the emitted white light. That is, the color saturation difference of white light
