Problems solved by technology

However, the current single-layer electrowetting electronic paper display device is a single-layer ink-filled structure, and the insulating hydrophobic layer 18 is only filled with one colored ink, so it can only display one color under the action of an applied electric field ( That is, the color of the filled ink), it is difficult to achieve full-color display, not comprehensive enough and the application range is small

Embodiment 1

[0037] Based on the structure of the traditional single-layer monochromatic electrowetting display device, the present invention proposes a three-layer structure electrowetting display device—full-color dynamic three-layer electronic paper. The electronic paper fills the three-layer insulating and hydrophobic layer structure with cyan, magenta and yellow inks (that is, printing three primary colors) inks. According to the subtractive color mixing principle of printing three primary colors, the switch of pixels in each layer is controlled by the controller ( That is, the driving waveform of the driver chip), to realize the superposition of different colors on the vertical structure, and then realize the full-color display.

[0038] Among them, the vertical structure of the three-layer electrowetting display device is as follows figure 2 As shown, the structure adds three different colors of ink, cyan, magenta, and yellow, to each layer from top to bottom. In the figure, each ...

Abstract

The invention discloses full-color dynamic three-layer electronic paper. The electronic paper comprises a substrate, a controller, a first electrowetting display layer, a second electrowetting display layer and a third electrowetting display layer. The first electrowetting display layer, the second electrowetting display layer and the third electrowetting display layer are formed by transparent upper pole plates, insulated hydrophobic layers, pixel walls, color printing ink, colorless liquids, transparent lower pole plates, packaging glues and driving chips. The driving chips are connected to the transparent upper pole plates and the transparent lower pole plates respectively. The transparent lower pole plate of the third electrowetting display layer is located above the substrate. The color printing ink filled in the first electrowetting display layer, the second electrowetting display layer and the third electrowetting display layer is cyan printing ink, carmine printing ink and yellow printing ink respectively. The controller controls voltage waveforms of the three driving chips to realize full-color display according to a subtractive mixing principle of three primary color printing. The electronic paper possesses advantages of comprehensiveness and a wide application scope and can be widely used in the electronic paper field.

Description

technical field [0001] The invention relates to the field of electronic paper, in particular to a full-color dynamic three-layer electronic paper. Background technique [0002] Electrowetting display technology is a new paper-like display technology that combines the advantages of ordinary paper and electronic display technology. Electrowetting display technology has a fast response time so that it can achieve dynamic display; compared with active light-emitting panels (such as LCD and AMOLED), electrowetting display panels do not require a backlight module, so electrowetting display has a low characteristics of power consumption. As a reflective display technology, the electrowetting display panel only needs ambient light to achieve the purpose of display, so it also has the advantages of high brightness, high contrast and wide viewing angle. [0003] In 2003, Philips' RobertA. The article published by Hayes and B.J.Feenstra in "Nature" first proposed the application pro...
