Electrophoretic display device

Abstract

The invention relates to an electrophoretic display device, which includes a driving array substrate, a color filter layer and an electrophoretic display film. The driving array substrate has a plurality of pixel units. Each pixel unit includes a driving element. The color filter layer is arranged on the driving array substrate and has a plurality of color filter patterns. Each color filter pattern corresponds to at least two pixel units. The electrophoretic display film is disposed between the driving array substrate and the color filter layer, and includes multiple display media. The display medium corresponding to each color filter pattern is controlled by at least two driving elements. By means of the present invention, the display quality that changes with the viewing angle can be improved.

Description

technical field [0001] The present invention relates to a display device, in particular to an electrophoretic display device. Background technique [0002] Electronic paper (e-paper) and electronic book (e-book) use electrophoretic display technology to achieve the purpose of display. Taking an e-book displaying black and white as an example, the display medium is mainly composed of black electrophoretic fluid and white charged particles mixed in the black electrophoretic fluid. By applying voltage, the white charged particles can be driven to move, so that each pixel can be displayed separately. Black, white or grayscale. [0003] In the prior art, most electrophoretic displays use the reflection of external light sources to achieve the purpose of display, and the white charged particles mixed in the electrophoretic fluid can be driven by voltage to make each pixel display the required gray scale. Moreover, in order to expand the application of the electrophoretic display...

AI Technical Summary

Problems solved by technology

When driving a single pixel unit, at the boundary between two adjacent filter patterns, human eyes will experience color deviation due to different viewing angles. Therefore, the conventional technology separates each filter pattern by setting a black matrix, so as to Improve the color shift problem, but relatively the black matrix will also cause the light transmittance to become smaller

[0005] This shows that above-mentioned existing electrophoretic display obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
