Embodiment 1

[0029] This embodiment provides a color filter substrate, including: a first base, a color filter layer on the first base; wherein, the color filter layer includes a plurality of color filters, and any two adjacent color filters between the black matrix; the color filter substrate in this embodiment also includes: a first electrode layer, a second electrode layer, and light-shielding particles located on the first substrate; wherein, the first electrode layer includes a plurality of first electrodes, And the first electrode and the color filter are arranged one by one; the light-shielding particles are used to move under the control of the electric field generated between the first electrode and the second electrode layer, so as to control the light transmission area of ​​the color filter.

[0030] Since the light-shielding particles are added to the color filter substrate of this embodiment, as well as the first electrode layer and the second electrode layer that control the m...

Embodiment 2

[0033] Such as figure 1 and 2 As shown, this embodiment provides a color filter substrate and a display device, wherein the color filter substrate is divided into a plurality of pixel areas A; the color filter substrate includes a first base 10, and a color filter layer is located on the first base 10; The color filter layer includes red, green, and blue color filters of three different colors (ie: red filter R, green filter G, blue filter B), and any two adjacent color filters The black matrix BM between the filters; wherein, each pixel area A includes three color filters, which are red filter R, green filter G, and blue filter B, and these The three color filters are arranged in a ring, that is, each color filter is similar to a fan. In particular, in the color filter substrate of this embodiment, a first electrode layer is provided between the first substrate 10 and the color filter layer, and the first electrode layer includes a plurality of first electrodes 1, and each ...

Abstract

The invention provides a color filter substrate and a display device, which belong to the field of display technology. The color filter substrate of the present invention includes: a first base, a color filter layer located on the first base; wherein, the color filter layer includes a plurality of color filters, and any two adjacent color filters are located A black matrix between the filters; the color filter substrate also includes: a first electrode layer, a second electrode layer, and light-shielding particles located on the first substrate; wherein, the first electrode layer includes a plurality of The first electrode, and the first electrode and the color filter are arranged one by one; the light-shielding particles are used to move under the action of the first electrode and the second electrode layer, so as to control the The light transmission area of ​​the color filter.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter substrate and a display device. Background technique [0002] Micro LED technology, that is, LED miniaturization and matrix technology. It refers to a high-density micro-sized LED array integrated on a chip. For example, each pixel of the LED display can be addressed and individually driven to light up. It can be regarded as a miniature version of the outdoor LED display. down to the micron level. [0003] As for the Micro LED display, the bottom layer uses the normal CMOS integrated circuit manufacturing process to make the LED display drive circuit, and then uses the MOCVD machine to make the LED array on the integrated circuit, thus realizing the micro display, that is, the so-called LED display. A smaller version of the screen. [0004] At present, the color display of Micro LED is mainly realized through the mixing of three colors of R, G, and ...
