Problems solved by technology

However, because the wavelength distribution range of the white light source S is relatively wide, the transmittance of the white light source S to the color filter layer 15 will not be high, thereby affecting the luminous brightness and light color saturation of the OLED display device 200, so it cannot Effectively improve its luminous quality

Embodiment Construction

[0058] In order to have a further understanding and understanding of the features, structures and effects of the present invention, the preferred embodiments and accompanying drawings are described in detail as follows:

[0059] First, see figure 2 , figure 2 It is a schematic cross-sectional view of a preferred embodiment of the light color filter conversion device of the present invention and its organic electroluminescence display device; There is at least one black matrix 33 (Black Matrix), and a color conversion layer 361 is provided on the part of the upper surface of the black matrix 33 and the part of the upper surface of the light-transmitting substrate 31 that is not provided with the black matrix 33, and the color conversion layer 361 is not provided. A first color photoresist 351 and a second color photoresist 353 are disposed on other positions of the transmissive substrate 31 of the conversion layer 361 . Over the black matrix 33, the color conversion layer 3...

Abstract

This invention relates to a light color filtering converting device and organic electroluminescence displayer, the former one mainly characterized in: integrating a color converting layer, a first colorful light resistance and a second colorful light resistance on a upper surface of a light-transparent plate, and equipping a second organic light-emitting unit in the vertical extension position of the second colorful resistance and color converting layer, effectively reducing deposition times of organic light-emitting unit, and increasing penetrance ratio of color light source to colorful light resistance and conversion efficiency color converting layer.

Description

technical field [0001] The invention relates to a light color filter conversion device, in particular to a light color filter conversion device and an organic electroluminescent display device using the light color filter conversion device, which can not only effectively improve display brightness and color scale, but also effectively Simplify manufacturing steps and increase production yield. Background technique [0002] Among many displays, full-color display technology is often the key to the success of the display. As far as organic electroluminescent display devices (OLEDs) are concerned, the most common methods to achieve full-color display effects are as follows: [0003] 1. Independent pixels of three primary colors emit light: the organic electroluminescent display devices that can produce the three primary colors of red (R), green (G) and blue (B) are separately set up (Side by Side), and the three color lights are distributed in an appropriate ratio Mix and matc...
