Problems solved by technology

[0003] However, due to the high transparency of the transparent display screen itself, the contrast ratio is low when displayed, and the color film as the basis of the color display causes a large loss of light transmittance, and one of its sub-pixels only corresponds to one of the three primary colors (RGB). Seriously affected the display performance of the transparent display

Abstract

The invention relates to an electrowetting display panel and a control method thereof. The electrowetting display panel comprises a plurality of pixel units; and each pixel unit consists of a plurality of sub pixel units. Each sub pixel unit includes at least two liquid layers and at least one electrode layer. Each liquid layer and each electrode layer are laminated alternately. Each liquid layer consists of liquid, a first insulation layer, a second insulation layer, and a side wall; the liquid is accommodated into the space encircled by the first insulation layer, the second insulation layer, and the side wall and includes a hydrophobic flow medium with a color and a transparent hydrophilic flow medium. And the insulation layer adjacent to the electrode layer in each liquid layer is a hydrophobic insulation layer.

Description

technical field [0001] The invention relates to electrowetting display technology, in particular to an electrowetting display panel and a control method thereof. Background technique [0002] With the continuous development of display technology, transparent display screens have become the research focus of various display panel manufacturers. Compared with traditional liquid crystal display screens, transparent display screens can bring users unprecedented visual experience and brand-new experience. Since the transparent screen itself has the characteristics of screen and transparency, it can be applied to many occasions, that is, it can be used as a screen and can replace transparent flat glass. The user can see objects or images on the opposite surface through the screen. [0003] However, due to the high transparency of the transparent display screen itself, the contrast ratio is low when displayed, and the color film as the basis of the color display causes a large los...
