Problems solved by technology

Therefore, it is generally believed that the "white light plus filter method" OLED panchromatic technology process structure has the problem of low luminous efficiency.
In addition, so far, in the research on OLED light-emitting materials, compared with red and green light-emitting materials, there is a huge gap in the service life and efficiency of blue OLED light-emitting materials, whether it is fluorescent materials or phosphorescent materials. The disadvantages in performance also lead to the disadvantages of the overall performance of the white light plus filter technology applied to the display, which further leads to the application limitations of the "white light plus filter method" full-color OLED display technology

Abstract

The invention relates to a full-color OLED (Organic Light Emitting Diode) display made by adopting a multi-component OLED luminescent device technology and filtering technology. The full-color OLED display comprises an optical filter substrate, an OLED luminescent device and a drive unit used for driving the OLED luminescent device to emit light, wherein each optical filter membrane layer in the optical filter substrate is provided with an OLED luminescent device corresponding to the optical filter membrane layer, and all OLED luminescent devices are the same in structures. The full-color OLED display is characterized in that electroluminescent luminescent spectrums generated by the OLED luminescent devices under the electrifying condition comprise at least two groups of groups of blue light luminescent components with CIE (Commission International Eclairage) color coordinate Y values of less than 0.55, red light luminescent components with CIE color coordinate X values of more than 0.64, and green light luminescent components with CIE color coordinate Y values of more than 0.55. The full-color OLED display has the advantages of long service life, high fineness, high yield, large size and the like, and is beneficial to the increase of the total manufacture cost performance of the display.

Description

technical field [0001] The invention relates to a full-color OLED display manufactured by combining multi-component OLED light-emitting device technology with light filtering technology, and belongs to the technical field of display manufacturing. Background technique [0002] In the prior art, there are usually three different production methods for full-color OLED displays: the first is to directly apply an electric field to different OLED light-emitting devices on the pixel matrix, so as to obtain independent red, green and blue light-emitting "red, green and blue three-primary color light-emitting The second method is to use different color filter films to cut the OLED light generated by the background white OLED light-emitting device, so as to obtain the "white light plus filter method" of red, green and blue three primary colors; the third is to pass the color The conversion film absorbs the effective OLED light-emitting components in the background ultraviolet, blue, ...
