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

A kind of surface discolouration device and colour-changing display screen curtain

Art

A kind of the present invention relates to device changing surface color and polish, and the screen for presentation of information being made up of this device multiple.

Background technology

The screen being presently used for public information display is mainly LED giant-screen or two kinds of LCD display, and their common features are to rely on itself The combination of luminous point constitutes writings and image.This requires that its own brightness have to be larger than ambient light, and people can be allowed to see clearly picture, for example Out of doors using mobile phone, often contents of mobile phone screen can not seen because sunlight is too strong.When having high brightness, when ambient light reduces, meeting again Make one to feel dazzling, particularly to night, according to biological law, strong light note allows people to feel ill, also can produce radiant heat with the time Amount, improves temperature nearby, the life of impact people, work, and often this is long toward allowing people's dysphoria, short-tempered, that is, cause light pollution.

Content of the invention

For solving the problems, such as light pollution, meet the needs to public information display for the people simultaneously, give people picture is presented with the new selection of effect.The present invention There is provided one kind do not light, do not generate heat, radiationless, its own face can change the device of color, and is shown by the variable color that this surface discolouration device is constituted Display screen curtain.

By the use of electroactive polymer as actuator, structure is simple.Its own can be in dilatation under electric field action, thus just producing in black chamber Pressure or negative pressure.When executor moves upwards, in black chamber, produce malleation, ink therein is squeezed and can cover through the partition with micropore, flow direction It is stamped film side, thin film has high resiliency in itself, surrounding is bonding with partition, middle part is subject to ink extrusion expansion, form an ink sac, in ink sac Ink cover original enamelled coating on partition thus reaching the purpose of variable color.When executor moves downward, produce negative pressure in black chamber, black intracavity portion goes out Existing vacuum, the ink in ink sac is sucked in black chamber through the micropore on partition, recovers ortho states and is close to partition, ink sac disappears, partition after film shrunk Upper original enamelled coating presents from newly.

Using this color-changing device as pixel dense arrangement, make a kind of colour-changing display screen, its structure be lattice structure as color-changing device common enclosure, On shell, executor, piston and ink are installed inside every lattice, partition covers on whole lattice structure, and each grid medium position is opened for partition Multiple micropores, thin film is imprinted with mode and prolongs grid frame shape being bonded on partition, makes each grid become an independent color-changing device.

Specific embodiment

In FIG in the middle part of visible partition (3) carry multiple micropores, each micro-pore diameter in 200-400 micron, as ink channel.Thin film (4) only have surrounding bonding with partition (3), expansion that middle part is collapsible, in off position under, partition (3) is close on thin film (4) surface On, because thin film is transparent material, so now apparatus surface presents partition (3) enamelled coating color.Ink (5) is stored in by shell (6), in the black chamber that piston (2), partition (3) collectively form.When switching on power, actuator (1) anamorphic stretching under electric field action, Piston is promoted so that black cavity volume is diminished, ink (5) is poured in the micropore in the middle part of partition (3) by compression, leads to there is elastomeric thin film (4) Constantly expand and form an ink sac as shown in Figure 2, the ink in membrane vesicle has just reached the mesh of surface discolouration after covering partition original enamelled coating color 's.Power supply actuator (1) after new disconnection shrinks, and black cavity volume expands, and vacuum, ink (5) is through micropore in the middle part of partition (3) It is inhaled into black chamber, with the loss of ink, thin film (4) is gradually reduced, so that membrane vesicle fades away, final thin film (4) is close to again On partition (3), once revealed partition (3) enamelled coating color.

Visible in figure 3 make a kind of colour-changing display screen using this color-changing device as pixel dense arrangement, its structure is lattice structure as variable color Device common enclosure (6), installs executor (1), piston (2) and ink (5) inside every lattice, partition (3) covering whole lattice structure it On, each grid medium position opens multiple micropores for partition, and thin film (4) mode of being imprinted with is prolonged grid frame shape and is bonded on partition (3), Each grid is made to become an independent color-changing device.

Claims
