Description

Technical Field

[0002] Semi-reflective and semi-transmissive color filters are used in mobile products such as mobile phones, and they have shown their unique advantages. In a darker indoor environment, the white light from the backlight passes through the color filter to obtain a bright color image. In a bright outdoor environment, sunlight enters the color filter and is reflected by the reflective film to obtain a brighter color image.

[0003] Publication number CN101246230B discloses a semi-transparent color filter, including a transparent substrate, and also including a color filter layer, a reflective layer and a transparent electrode layer arranged in sequence along the direction opposite to the transparent substrate, the color filter layer includes a plurality of pixels, each pixel includes three sub-pixels, and the reflective layer includes a plurality of isolated reflective films, and the reflective film is located on each sub-pixel of the color filter layer. The invention also discloses a method for making a semi-transparent color filter, including the following steps: making a transparent substrate; making a BM layer and a color filter layer on one side of the transparent substrate; coating a reflective layer on the color filter layer and etching to form a reflective pattern; coating a flat layer; and coating a transparent electrode layer on the flat layer. In the reflection mode, since the reflective layer of the semi-transparent color filter is above the color filter layer, the external light does not pass through the color filter layer but directly reflects on the reflective layer, and the reflection brightness is greatly enhanced. The semi-transparent color filter of the invention has simple production and process control, and low cost.
