Embodiment Construction

[0024] The invention provides a photosensitive hardening composition, which contains 5-15wt% polymer resin, 1-5wt% photoinitiator, 5-10wt% monomer, 50-90wt% solvent, 1-6wt% % pigment and 0-2wt% additive, and the CIE chromaticity coordinate values ​​of the photosensitive hardening composition are x=0.32-0.36, y=0.3-0.335, Y=64.9%-79%, wherein the pigment is 10 ~100wt% of red pigment, 0~25wt% of blue pigment, 0~65wt% of green pigment, 0~45wt% of yellow pigment or a combination of at least two kinds of pigments, such as a combination of yellow pigment and red pigment , a combination of blue, green and red pigments. Moreover, the film thickness of the photosensitive hardening composition ranges from 0.4 to 1.6 um.

[0025] And the photosensitive curable composition of the present invention is applied to organic electroluminescent displays, such as figure 1 In the illustrated embodiment, the organic electroluminescent display mainly has a substrate with driving elements, which is...

Abstract

The invention discloses a photosensitive hardening composition containing 5-15wt% of high molecular resin, 1-5wt% of a photosensitive initiator, 5-10wt% of a monomer, 50-90wt% of a solvent, 1-6wt% of a pigment and 0-2wt% of an additive, CIE chromaticity coordinate values of the photosensitive hardening composition are as follows: x = 0.32-0.36, y = 0.3-0.335, Y = 64.9%-79%, the photosensitive hardening composition is used in organic electroluminescent displays, can effectively eliminate reflected light produced by ambient light, reduces the reflectivity of an inner metal layer of the organic electroluminescent displays, and improves the contrast.

Description

technical field [0001] The present invention relates to a photosensitive hardening composition, especially a photosensitive hardening composition that can be applied to organic electroluminescent displays to effectively eliminate reflected light generated by ambient light sources. Background technique [0002] Organic electroluminescent displays (organic electroluminescent devices) (also known as organic light emitting diode (OLED) display) its light-emitting principle is based on organic molecular materials (which can be divided into small molecule materials (small molecule materials) according to their molecular weights. material) and polymer material (polymermaterial)) apply an external electric field to cause luminescence. Due to its self emission, organic electroluminescent displays can be displayed in arrays (dot matrix type display), with light and thin, high contrast, low power consumption, high resolution, short response time (fast response time), no Backlight and ...
