Pixel structure for displaying device and displaying device

Abstract

The invention provides a pixel structure for a displaying device and the displaying device, wherein the pixel structure uses a light entering from the outside of the displaying device as a light source. The pixel structure comprises a first substrate, a light barrier layer, an active element and a moveable light shielding layer, wherein the light barrier layer is arranged on the first substrate and provided with a transparent area and a lightproof area; the active element is arranged in the lightproof area of the light barrier layer and has a first state and a second state; and the moveable light shielding layer is arranged on the light barrier layer and the active element. When the active element is in the first state, the moveable light shielding layer properly shields the transparent area so as to prevent the light from emitting out from the first substrate; and when the active element is in the second state, the moveable light shielding layer is driven to allow the light ray to passes through the transparent area and to be projected out from the first substrate.

Description

Technical field [0001] The present invention relates to a display device; in particular, it relates to a pixel structure applied to an electrowetting display device, and an electrowetting display device using the pixel structure. Background technique [0002] With the rapid development of technology, various portable electronic devices, such as mobile phones, personal digital assistants (PDAs), digital cameras, digital cameras, etc., have brought great convenience to human life, and their specifications and functions have also become more and more convenient. diversification. Among them, display technologies for portable electronic devices are constantly being developed to meet various needs. [0003] Since portable electronic devices emphasize small size and light weight for easy portability, portable electronic devices must also save power to extend battery life and avoid the trouble of frequent charging. Among them, a reflective display using external ambient light as a light ...

Problems solved by technology

However, the transparent electrode layer 14 is made on the opposite side substrate of the substrate 11. If one more layer of black matrix 17 is to be added on the transparent electrode layer 14, the opposite side substrate printed with the black matrix 17 and the transparent electrode layer 14 will be in the manufacturing process. , it needs to be precisely aligned with the substrate 11 and packaged. This step will increase the difficulty of manufacturing and increase the manufacturing cost.

Moreover, when coating reflective material on or under the reflective electrode layer 12, the distribution position of the thin film transistors must also be avoided, and an appropriate photomask must be used to perform the patterning process, thereby increasing the complexity and cost of the process.
