Abstract
The invention relates to a reflecting display device which comprises a light-transmitting base plate, a reflecting base plate, a display layer and a transparent gluing layer which is arranged between the light-transmitting base plate and the display layer. The light refractive index of the transparent gluing layer of the reflecting display device disclosed by the invention is generally the same as that of the light-transmitting base plate, therefore the transmission loss rate at the junction of the transparent gluing layer and the light-transmitting base plate can be reduced to further improve the image display brightness of the reflecting display device.
Description
Technical field
The present invention relates to a kind of reflective display, relate in particular to the good reflective display of a kind of smooth exitance.
Background technology
Reflected displaying device can utilize environment light source around to originate with show image, with traditional penetration display comparatively energy-conserving and environment-protective in comparison as illumination.
The light luminance that the image display quality of reflected displaying device reflects with it is closely related, if surround lighting is brighter and reflected displaying device is higher to environment reflection of light utilization factor, the shown picture of display also will be clearer.But in the time that light enters another medium by a medium, the intersection of two media can produce because of the energy loss that reflection causes (being referred to as Fresnel loss (Fresnel Loss)).For instance, when light is incident to glass from air, be approximately 7%～8% at the reflectivity of intersection.Hence one can see that, how to reduce the proportion of goods damageds of light in reflected displaying device inside, so that the utilization rate of incident light reaches optimization, in fact by industry is paid close attention to.
Summary of the invention
Object of the present invention is exactly to be to provide the reflective display that a kind of light loss is low and light extraction efficiency is good.
The invention provides a kind of reflective display, it comprises reflection substrate, transparent substrates, display layer and transparent rubberised layer.Display layer is disposed on reflection substrate, and transparent substrates is disposed at the top of display layer, and transparent rubberised layer is to be disposed between transparent substrates and display layer, and described transparent rubberised layer is directly contacted with described display layer.And the optical index of transparent rubberised layer and the optical index of transparent substrates are roughly the same, to reduce the energy in described transparent substrates and the place loss of described transparent rubberised layer boundary via the light of described smooth reflection substrate reflection.Also include multiple color filter films, be formed on transparent substrates and between transparent substrates and display layer, and transparent rubberised layer is directly contacted with described color filter film.
In one embodiment of this invention, aforesaid display layer can be liquid crystal layer, electric moistening display layer or electrophoresis showed layer, as microcapsules formula electrophoresis showed layer, micro-cup type electrophoresis showed layer or micro-plough groove type electrophoresis showed layer.
In one embodiment of this invention, the optical index of aforesaid transparent rubberised layer is more than or equal to 1.4 and be less than or equal to 1.7.
In one embodiment of this invention, the material of aforesaid transparent rubberised layer can be epoxy resin, acryl or silica gel.
In one embodiment of this invention, aforesaid transparent substrates can be contact panel.
As from the foregoing, the present invention because disposing the roughly the same transparent rubberised layer of optical index and transparent substrates between transparent substrates and display layer, therefore the proportion of goods damageds can reduce light by reflective display outgoing time, and then improve the display brightness of reflective display.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of reflective display, method, step, structure, feature and effect of proposing according to the present invention, be described in detail as follows.
Relevant aforementioned and other technology contents of the present invention, Characteristic, can clearly present in following cooperation in describing in detail with reference to graphic preferred embodiment.By the explanation of embodiment, can have one more deeply and concrete understanding for technological means and effect of reaching predetermined object and taking to the present invention, but appended graphic be only to provide with reference to the use of explanation, be not used for the present invention to be limited.
Please refer to Fig. 1, in one embodiment of the invention, reflective display 100 comprises transparent substrates 110, reflection substrate 120, display layer 130 and transparent rubberised layer 140.Display layer 130 is disposed on reflection substrate 120, and transparent substrates 110 is disposed at the top of display layer 130, and 140 of transparent rubberised layers are disposed between transparent substrates 110 and display layer 130.Specifically, reflection substrate 120 for example comprises pixel cell (not shown), and each pixel cell has respectively a reflecting surface 122, and display layer 130 covers these reflectings surface 122.In the present embodiment, display layer 130 is for example liquid crystal layer, but the invention is not restricted to this.In other embodiments, display layer 130 can be also electrophoresis layer, as micro-cup type electrophoresis layer, microcapsules formula electrophoresis layer or micro-plough groove type electrophoresis layer.In addition, display layer 130 can be also electric wettable layer.
Specifically, transparent rubberised layer 140 is roughly the same with the optical index of transparent substrates 110, with reduce the light L being reflected via reflection substrate at transparent substrates 110 energy with transparent rubberised layer 140 place, boundary losses.In the present embodiment, transparent rubberised layer 140 optical indexs approximately between 1.4 to 1.7, and are preferably 1.5.And the material of transparent rubberised layer 140 can be epoxy resin (Epoxy), acryl (acrylic) or silica gel (slilcone).Specifically, transparent rubberised layer 140 can be sheet material or is solidified and formed by liquid material.
Please continue to refer to Fig. 1, in the present embodiment, on transparent substrates 110, be for example formed with multiple color filter films (color filter film) 114.Specifically, these color filter films can comprise red filter coating, blue filter coating and green filter film.In other words, display layer 130 tops dispose colored filter 150, and colored filter 150 is made up of color filter film 114 and transparent substrates 110.
Certainly, in other embodiments, transparent substrates 110 can be also contact panel, but the invention is not restricted to this.
In sum, reflective display of the present invention configures one deck optical index and the roughly the same transparent rubberised layer of transparent substrates between transparent substrates and display layer, therefore the proportion of goods damageds can significantly reduce the outgoing of reflective display internal light time, and then the brightness that improves reflective display show image.
