Description
Technical field
The invention relates to a kind of flat display board and display device, particularly about a kind of transparent liquid crystal display board and there is the transparent display device of transparent liquid crystal display board.
Background technology
Growing along with display technique, various new techniques continue to bring out, and transparent display technique, because of its this characteristic of transparent display board and unique application thereof, more and more receives people's concern.
The core of transparent display technique is transparent display board, and transparent display board is a kind of transparent panel that can show image, and it is different from traditional double-sided display technology, and double-sided display plate is a kind ofly can show in display board both sides the display device of image simultaneously.Transparent display board is when closing, and plate is a clear glass seemingly just; When its work, beholder not only can watch onboard the content showing, simultaneously can also transmitting plate watches the object placed after plate and background etc.The optical characteristics of this uniqueness of transparent display board has determined its extensive use in information display field, especially in the application in the fields such as advertising display, image display, interaction in kind, special optical glass application, realize the multidimensional communication modes such as article display, audio-visual broadcasting, human-computer interaction carries out simultaneously, more visual pattern, has more visual impact.
The various display techniques such as liquid crystal display, organic light emitting diode display and PDP display of transparent demonstration and the transparent display techniques that some are novel of being applied to had been developed gradually in the last few years.Wherein, for utilizing liquid crystal display to realize the technology of transparent demonstration, the non-self luminous display device that it is made, only utilize ambient light or backlight can realize demonstration, its have simple in structure, working environment requirement is wide in range, manufacture and the feature such as use cost is cheap, has wide market outlook.The basic structure of transparent liquid crystal display used in the prior art is structure as disclosed in the patent of Chinese Patent Application No. 98801067.4 conventionally: a kind of liquid crystal indicator, it is characterized in that, this device is become by lower fan's part Chinese holly: on inner face in opposite directions, have respectively the liquid crystal cells of having enclosed liquid crystal between 2 transparent substrates of electrode, be disposed at watching of this liquid crystal cells absorption polarization plate side, that absorb the linearly polarized light with the direction vibration plane vertical with the easy axis of homology; Be configured to the reflection type polarization tabula rasa contrary side of a side, that reflect the linearly polarized light of the vibration plane with the direction vertical with the easy axis of homology with watching of above-mentioned liquid crystal cells; And the color filter between a side or this absorption polarization plate and upper fan's reflection type polarization tabula rasa of watching that is configured to the absorption polarization plate of fan.
Yet there is many technical matterss in existing transparent liquid crystal display.First, the light absorption of each layer in process sandwich construction in transparent liquid crystal display in existing product, cause light transmission rate to reduce, contrast reduces, for example, the colour of realizing transparent liquid crystal display screen shows, conventionally need to use red, green, blue three look filter discs, color filter can absorb light, and ambient light intensity is often lower, this must cause the transparency of display board to reduce, if reduce colour filter intensity, although can enhance the transparency, but this also must cause contrast to reduce, although can adopt, set up optical sheet and light guide plate can compensate ambient light, but can increase structural complexity undoubtedly, obviously caused the complexity of manufacture craft, manufacture and maintenance cost have been increased, and very easily cause display yield rate to reduce, simultaneously, this design easily causes display board light source interference environment light source, cause the article identification of showing, the shortcomings such as bandwagon effect is not good, secondly, existing transparent liquid crystal display is difficult to realize large scale and shows, substantially rests in 32inch, is difficult to meet large-scale showpiece and shows demand, has limited its application in numerous areas.
For improving light transmission rate, in prior art, mainly contain following solution:
1. the patent that Chinese Patent Application No. is 20121017997.3 discloses and further provides a kind of and increase transparent subpixel area and with the technical scheme of the polaroid of unpolarizedization pattern: a kind of transparent display, it is characterized in that comprising: LCD panel display unit, described LCD panel display unit comprises: color membrane substrates, array base palte, be located in the liquid crystal layer between described color membrane substrates and described array base palte, the first polaroid and the second polaroid, described the first polaroid is arranged at described color membrane substrates away from a side of described liquid crystal layer, described the second polaroid is arranged at described array base palte away from a side of described liquid crystal layer, described color membrane substrates comprises the first transparency carrier and is formed at the color filter film on described the first transparency carrier, described color filter film comprises a plurality of composite pixel region, wherein each composite pixel region comprises a plurality of color sub-pixel region and a transparent sub-pixel area, described the second polaroid comprises unpolarizedization pattern, described unpolarizedization pattern is spatially corresponding with the transparent subpixel area in described color filter film, light does not change through described its polarization state of unpolarizedization pattern.Yet, in the production run of traditional polaroid, increase the process of unpolarizedization pattern, further increased production difficulty and defect rate, reduced the versatility of production line.
2. Chinese Patent Application No. is 201220196846.3, the patent of 201310006342.X all discloses a kind of technical scheme that adopts circular polarizing disk to replace linear polarizer: a kind of transparent display surface machine is characterized in that, comprising: the display panels that liquid crystal is arranged with vertical alignment; The first rotatory polarization sheet, is attached to the first surface of described display panels: the second rotatory polarization sheet, is attached to the second surface of described display panels.Described the first rotatory polarization sheet comprises the PVA that is superimposed and λ/4 plate wherein, described λ/4 plate is attached to the described first surface of described display panels, the slow-axis direction angle at 45 ° that sees through direction of principal axis and described λ/4 plate of a described PVA, described λ is light wavelength, and described the second rotatory polarization sheet comprises the 2nd PVA and the 2nd λ/4 plate being superimposed; Wherein, described the 2nd λ/4 plate is attached to the described second surface of described display panels, the slow-axis direction angle at 45 ° that sees through direction of principal axis and described the 2nd λ/4 plate of described the 2nd PVA.Yet, adopt this circular polarizing disk being formed with λ/4 plate by PVA increased together with production process, simultaneously, every increase one deck structure, must bring once the absorption of light, increase the loss of transmitted light, still need to increase backlight at side and carry out light filling, its antireflective effect using is separately also very limited, and nonideal anti-reflection scheme.
