Description
Technical field
The invention provides a kind of display, be specifically related to a kind of reflected displaying device, belong to electronic applications.
Background technology
In current existing display, TFT-LCD display occupies the very large market share, and this performance excellent with it and lower production cost are closely bound up.
Traditional TFT-LCD is based on transmission principle, and its display pannel can be considered two panels glass substrate sandwich one deck liquid crystal, and wherein the glass substrate of lower floor is all inlaid with a thin film transistor (TFT) (TFT) in each pixel.The function of TFT is crosstalk when effectively overcoming non-gated, the static characteristics of display liquid crystal display and number of scanning lines are had nothing to do, thus greatly improves picture quality, namely as a voltage cut-out, reach the write and maintenance that control pixel voltages on display, and then reach the object of addressing.
Because traditional TFT-LCD is based on transmission principle, backlight enters human eye through crystal liquid substrate, the TFT that substrate is inlayed is among light path, and its volume has a significant impact the intensity in transmission of backlight and display effect, and TFT volume should reduce on the basis of retention as far as possible.Reduce TFT volume and can increase technological development and production cost again, the processing simultaneously carrying out tft array when large-size screen monitors shows in large-area glass also tool acquires a certain degree of difficulty, and thus traditional TFT-LCD is difficult to realize large-size screen monitors and shows.
Summary of the invention
The invention provides a kind of reflected displaying device, solve the deficiency in above-mentioned background technology, its structure is simple, and production cost and process specifications are all lower.
Realizing the technical scheme that above-mentioned purpose of the present invention adopts is:
A kind of reflected displaying device, comprise the transparent electrode layer, electric control optical switch layer, reflecting electrode pcb layer and the TFT layer that stack gradually from top to bottom, wherein transparent electrode layer is the electrode be made up of transparent conductive material, electric control optical switch layer is the photoswitch layer that can realize light switch function under electric field action, reflecting electrode pcb layer is the wiring board combination simultaneously with electrode, reflection and coloring function, and TFT layer is positioned at the below of circuit board.The matrix of described wiring board combination is wiring board, wiring board has been attached with the pad of electrode effect, pad has been attached with one deck reflecting material, reflecting material has been printed with the color layer of the net-point shape of the arrangement in matrix.
Described wiring board is flexible circuit board.
Described transparent electrode layer is attached with diffuse reflector, and diffuse reflector is matt film or the gloss oil with diffuse reflection function.
Described diffuse reflector is attached with protective seam.
Protective seam is the film of protection display screen from damage, preferred acrylic resin film or aluminum oxide film.
Reflected displaying device provided by the invention has following advantage: 1, this display is based on reflective principle, namely utilizes external environment light source to enter human eye through substrate reflection and carrys out show image.After TFT is structurally placed on substrate by reflected displaying device provided by the invention, the incidence of light and reflection are all without TFT layer, thus TFT layer existence can not to light through and display effect have an impact, thus in technique, the volume requirement of TFT layer is reduced, and then reducing technical requirement and production cost, preparation is simple.This display is based on principle of reflection display without the need to using backlight simultaneously, therefore can reduce power consumption, economize energy during display work.
2, use pdlc film to do electric control optical switch layer in the present invention, its low in energy consumption, fast response time, can meet the requirement of Dynamic Announce.
3, the pad in this reflecting electrode pcb layer presents flexibility, and the reflecting material that pad adheres to and transparent electrode layer all select flexible material, then reducing in conjunction with TFT layer volume, and this display can realize Flexible Displays.
4, the reflecting material in the present invention on wiring board can select aluminium coated, and aluminium coated is very strong to the reflection potential of light, can increase display brightness, and aluminium is originally as conductor simultaneously, therefore can also play the effect of electrode.If the pad itself simultaneously in the present invention on wiring board is aluminium, then do not need separately to add reflecting material.
Accompanying drawing explanation
Fig. 1 is the structural representation of reflected displaying device provided by the invention.
Embodiment
Below in conjunction with accompanying drawing, detailed specific description is done to the present invention.
The structure of reflected displaying device provided by the invention as shown in Figure 1, is followed successively by protective seam, diffuse reflector, transparent electrode layer, electric control optical switch layer, reflecting electrode pcb layer and TFT layer from top to bottom.Reflecting electrode pcb layer is the wiring board combination simultaneously with electrode, reflection and coloring function, the matrix of described wiring board combination is wiring board, wiring board is attached with the pad of electrode effect, pad is attached with one deck reflecting material, reflecting material is printed with the color layer of the net-point shape of the arrangement in matrix.In the present embodiment, the material of pad is flexible, and therefore wiring board is flexible circuit board.Reflecting material can select alumina based material to plate in the circuit board, because aluminium coated surface is more smooth, can play reflex, again because aluminium is excellence conductor, therefore aluminium coated can also play electrode effect.Color layer is printed on aluminium coated, the net-point shape of the arrangement in matrix, the all corresponding pixel in each site, be all added with red green blue tricolor, and the different gray scale variation utilizing it to have separately blends various different color thus display color in each pixel.TFT layer is positioned at the below of wiring board, its small volume.
Electric control optical switch layer is the photoswitch layer containing polymers compositions that can realize light switch function under electric field action, selects PDLC film in the present embodiment.Transparent electrode layer is the electrode be made up of transparent conductive material, selects ITO conductive film in the present embodiment.Protective seam is attached on diffuse reflector, and protective seam is the film of protection display screen from damage, preferred acrylic resin film or aluminum oxide film.Diffuse reflector is attached on transparent electrode layer, and in the present embodiment, diffuse reflector is matt film or the gloss oil with diffuse reflection function.
The principle of work of reflected displaying device provided by the invention is as follows: display layer is used for presenting color and level, transparent electrode layer and aluminium coated is respectively equipped with above and below PDLC film, when energized, it is opening that PDLC film is subject to field effect, and now extraneous incident light to enter in display and after aluminium coated reflection, the color reflection of display layer entered human eye.After TFT is placed on wiring board, therefore the incidence of light with reflection all without TFT layer, thus TFT existence can not to light through and display effect have an impact, thus can structurally by the as far as possible reduction on the basis of retention of the volume of TFT.Meanwhile wiring board selects flexible circuit board, and therefore the entirety of this display can in flexible.
