Electrowetting display panel, manufacturing method thereof, and display device

Abstract

The invention provides an electrowetting display panel and a manufacturing method thereof, and a display device and belongs to the field of display. The electrowetting display panel includes a first underlayer substrate, a second underlayer substrate arranged to be opposite to the first underlayer substrate, and a plurality of pixel units arranged on the first underlayer substrate. A plurality of thin film transistor switches which are in one-to-one correspondence with the plurality of pixel units are arranged on the first underlayer substrate. A reflection layer is arranged on the first underlayer substrate and at least part of the reflection layer is capable of shielding the thin film transistor switches. The technical scheme is capable of improving the display luminance of the display panel and reducing the power consumption of the display panel.

Description

technical field [0001] The present invention relates to the display field, in particular to an electrowetting display panel, a manufacturing method thereof, and a display device. Background technique [0002] Electrowetting display is a display technology developed in recent years. It uses the influence of interfacial charge on interfacial tension to change the contact angle of the droplet, which causes the droplet to spread or shrink, resulting in a change in the display area. . Electrowetting is widely used in electronic paper display, liquid light valve, microfluidic chip and other fields. [0003] figure 1 with figure 2 It is a schematic cross-sectional view of an existing electrowetting display. Such as figure 1 As shown, the existing electrowetting display includes a first base substrate 1 and a second base substrate 17 arranged oppositely, a pixel electrode 10, a common electrode 16, a barrier layer 11, and a hydrophobic layer 12 arranged between the two substra...

AI Technical Summary

Problems solved by technology

[0006] Existing electrowetting displays generally apply voltage to pixel electrodes through thin film transistor switches, but since electrowetting displays do not have a black matrix, external light will affect the performance of thin film transistors and affect the display of the screen In addition, when a voltage is applied, since the pixel electrode is generally made of ITO, the light transmission is better and the reflection performance is poor, resulting in darker reflected light of the electrowetting display, which makes the display contrast lower and affects the display effect, while If you want to increase the contrast of the display, it is necessary to increase the power consumption of the electrowetting display
