Colour filter concurrently having luminous brightness and photochromic contrast

Abstract

In the invention, a black matrix is setup on partial upper surface of a transparent base plate so as to define out multiple pixels. At least a color photoresistive and a hollowing out part are respective setup inside each pixel. Without influence on brightness of penetration light source, the hollowing out part reaches purpose of raising photochromic contrast of penetration light source.

Description

technical field [0001] The invention relates to a color filter, in particular to a color filter with both luminous brightness and light-color contrast. Through the setting of the hollow part, the penetration can be improved without affecting the brightness of the penetrating light source. The purpose of the light color contrast of the light source. Background technique [0002] With the vigorous development of the optoelectronic industry, people enjoy the convenience brought by technology. However, how to manufacture high-quality and low-cost flat-panel displays has always been the goal of major panel manufacturers, and for various displays, how to achieve full-color display is often the key to the success of the display. The key, among them, as far as organic electroluminescent display devices are concerned, the most common methods to achieve full color are the following two: [0003] 1. An organic electroluminescence device that can generate three primary colors of red (...

Problems solved by technology

However, as the thickness H of the first color photoresist 151 increases, the brightness of the first color light L1 will be reduced, thereby affecting the luminance of the organic electroluminescence device 100

Conversely, if the thickness H of the first color photoresist 151 is reduced, although the luminous brightness of the first color light L1 can be increased, the light-color contrast of the organic electroluminescent device 100 will be affected.
