Problems solved by technology

When white light passes through the color filter film, only one color of light can pass through, and other colors of light will be absorbed; therefore, the utilization rate of light is low, generally less than 1 / 3

Embodiment 2

[0094] Embodiment two: if Figure 4 As shown, blue OLED is used, red and green pixels use red quantum dot film and green quantum dot film respectively instead of traditional red and green filter films, and blue pixels use the light emission of blue OLED itself or traditional blue filter, that is ( Red QD+Green QD+Blue OLED or blue traditional filter).

[0095] The color OLED display adopts the production of blue OLED plus the corresponding (red, green) color quantum dot pixel color-changing film, and the blue pixel area uses the blue OLED itself to emit light, and the blue quantum dot film can also be used to improve the display color effect; (red, green) Green) The method of quantum dot pixel is the same as method 1. Take the blue OLED, the blue pixel uses the blue OLED itself to emit light as an example: image 3

Embodiment 3

[0096] Embodiment 3: adopt (green+blue) OLED to emit light, its red pixel uses red quantum dot film, blue, green pixel uses traditional blue, green filter; color film+traditional blue filter+green filter.

Embodiment 4

[0097] Embodiment 4: Use (green + blue) OLED to emit light, its red and green pixels use red and green quantum dot films, and blue pixels use traditional blue filters; that is: use blue and green OLEDs, use red and green QD color filter+traditional blue-green light film, where the wavelength of OLED green light can be smaller than that of QD green light.

Abstract

The invention relates to the technical field of display, and particularly relates to a manufacturing method of a high-efficiency light conversion color display film. The manufacturing method comprisesthe following steps that A) a substrate is provided and the substrate is cleaned; B) a pixel isolation wall is manufactured on the cleaned substrate; C) the quantum dot material of the correspondingcolor is printed in the designed pixel area; D) a transparent protection layer is additionally arranged on the prepared quantum dots; and E) the quantum dot plate is aligned and fit with the corresponding OLED display pixels so as to form a color display device. The beneficial effects of the manufacturing method are that the following advantages can be obtained by application of the manufacturingmethod of the high-efficiency light conversion color display pixel film: 1) the light utilization rate can be enhanced for multiple times; 2) the display color area is extended so that the display color is enabled to be better; and 3) the monochrome display device can be colorized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a high-efficiency light conversion color display pixel film. Background technique [0002] At present, OLED display devices, such as: OLED TV, mobile phone OLED display, etc., all use white OLED plus (red, green, blue) color filter films to achieve full-color display. When white light passes through the color filter film, only one color of light can pass through, and other colors of light will be absorbed; therefore, the utilization rate of light is low, generally less than 1 / 3. The present invention is to add red quantum dots, or add red and green quantum dots, or add red, green and blue quantum dots to replace (red, green, blue) color filter films on the front end of the OLED display to realize full-color display , because the quantum dot material converts the light of the OLED and then emits light independently, so that the light utilization rate i...
