Embodiment Construction

[0019] exist figure 1 It can be seen that the middle part of the separator (3) has a plurality of micropores, and each micropore has a diameter of 200-400 microns, which is used as an ink channel. The film (4) is only bonded to the spacer (3) around the periphery, and the middle part can shrink and expand. In the closed state, the surface of the film (4) is close to the spacer (3). Since the film is a transparent material, at this time The surface of the device exhibits the color of the paint layer of the spacer (3). The ink (5) is stored in the ink chamber jointly formed by the casing (6), the piston (2) and the diaphragm (3). When the power is turned on, the actuator (1) deforms and elongates under the action of the electric field, pushing the piston to make the volume of the ink chamber smaller, and the ink (5) is compressed and rushes into the micropores in the middle of the spacer (3), resulting in high elasticity The thin film (4) expands continuously to form a figur...

Abstract

The invention discloses a surface color-changing device, and a screen which consists of a plurality of surface color-changing devices and is used for information display. The device takes an electroactive polymer as an actuator, is simple in structure, generates a positive voltage or negative voltage to an ink cavity through the characteristic of deformation caused by expansion and shrinkage under the action of an electric field, and causes ink to move between the cavities with micropore partitioning pieces at two sides and a membrane sac, thereby achieving the purpose of surface color changing. One surface color-changing device is taken as a pixel, and a plurality of surface color-changing devices are densely arranged to form the color-changing display screen which can display characters and images.

Description

[0001] Field [0002] The invention relates to a device for changing surface color, and a screen for information display composed of a plurality of the devices. Background technique [0003] At present, the screens used for public information display are mainly LED large screens or LCD display screens. Their common feature is that they rely on the combination of their own light-emitting points to form text and images. This requires that its own brightness must be greater than the ambient light so that people can see a clear picture. For example, when using a mobile phone outdoors, it is often difficult to see the content of the mobile phone screen because the sunlight is too strong. When it has high brightness, it will make people feel dazzling when the ambient light is reduced, especially at night. According to biological laws, strong light will make people feel uncomfortable. At the same time, the light will also generate radiant heat and increase the temperature nearby. Af...
