Abstract

The invention discloses an electrowetting display panel and an electrowetting display device. The electrowetting display panel comprises a waveguide layer, a first electrode layer, a light emitting control layer, a second electrode layer and a first substrate, the first electrode layer is arranged on one side of the waveguide layer; the light emitting control layer is arranged on one side, far away from the waveguide layer, of the first electrode layer; the second electrode layer is arranged on one side, far away from the first electrode layer, of the light emitting control layer; the first substrate is arranged on one side, far away from the light emitting control layer, of the second electrode layer; wherein the material of the waveguide layer comprises a selenium-containing heterocyclic polymer. Stable propagation of light beams in the waveguide layer is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an electrowetting display panel and an electrowetting display device. Background technique [0002] Electrowetting display technology is a display technology that uses the principle of electrowetting to display images. Because electrowetting display technology can control the transmission and reflection of incident light with high selectivity, it can achieve high contrast and high image quality display. Effect. [0003] The display principle of electrowetting display technology is: by changing the voltage between the liquid and the insulating substrate, the wettability of the liquid on the insulating substrate (that is, changing the contact angle) is changed, so that the liquid can cover the waveguide under the insulating substrate to varying degrees. layer, and couples a set amount of light from the waveguide layer to achieve grayscale display. However, in the ...
