Display floater 120 is configured on the exiting surface 114a of light guide plate 114.Display floater 120 can be penetration display floater or half-transparent half-reflection display floater.In this example it is shown that panel 120 includes image element array substrates 122, relative to the opposite substrate 124 of image element array substrates 122 and the display medium 126 between image element array substrates 122 and opposite substrate 124.If display floater 120 is display panels (i.e. display medium 126 is liquid crystal), then display floater 120 more can farther include to be respectively configured image element array substrates 122 and two polaroids 128 on opposite substrate 124.But, the form of the display floater of the present invention is not limited to above-mentioned, and in other embodiments, display floater 120 also can be other type of display device.All illuminating bundle L that can be sent by light source 112 through and make user watch a display picture, can by background light beam X through and make user view and admire a background frame display device all in the category that the display floater of the present invention to be protected.
Switching panel 130 and backlight module 110 are arranged at the same side of display floater 120.Furthermore, switching panel 130 and backlight module 110 may be disposed at the side near the background light source sending background light beam X.In the present embodiment, light guide plate 114 is configured in switching between panel 130 and display floater 120.But, the invention is not restricted to this, Fig. 2 is the generalized section of the transparent display of another embodiment of the present invention, refer to Fig. 2, transparent display 100A is similar to transparent display 100, thus like assembly represents with identical label, and in transparent display 100A, switching panel 130 is also configured between light guide plate 114 and display floater 120.
Referring again to Fig. 1, switching panel 130 includes first substrate 132, the second substrate 134 relative to first substrate 132, the polymer dispersed liquid crystal layer 136 being configured between first substrate 132 and second substrate 134, the first electrode layer 138 being configured between first substrate 132 and polymer dispersed liquid crystal layer 136 and the second electrode lay 139 being configured between polymer dispersed liquid crystal layer 136 and second substrate 134.Particularly, the first electrode layer 138 is divided into separated from one another and the most independent multiple first electrode pattern 138a.Fig. 3 is the upper schematic diagram of the switching panel of Fig. 1, refer to Fig. 3, and in the present embodiment, each first electrode pattern 138a can be rectangular, and multiple first electrode pattern 138a can line up an array.In other words, multiple first electrode pattern 138a can be arranged in the form of nine grids.But, it should be noted that, multiple first electrode pattern 138a of Fig. 3 are to illustrate the present invention, and are not used to limit the present invention.The all visual actual demand of the shape of each first electrode pattern 138a and the arrangement mode of multiple first electrode pattern 138a does suitable design.All multiple electrode patterns that can be the most independently operated are all in the category that multiple first electrode patterns of the present invention to be protected.
It is noted that as it is shown in figure 1, through the most independent multiple first electrode pattern 138a, transparent display 100 can be divided into Transparence Display district R1 and nontransparent viewing area R2 by switching panel 130.Transparence Display district R1 shows picture and background frame in order to the part showing display floater 120 simultaneously.Nontransparent viewing area R2 is in order to show that the display picture of another part of display floater 120 is difficult to display background picture.
In detail, as shown in Figure 1, when transparent display 100 is in a part of transparent part nontransparent display pattern, a potential difference is there is essentially between at least one the first electrode pattern 138b and the second electrode lay 139, so that the transparent state of part polymer dispersed liquid crystal layer 136 overlapped with the first electrode pattern 138b.Now, the background light beam X of part may pass through the polymer dispersed liquid crystal layer 136 of transparent state, light guide plate 114 and display floater 120, and forms a background frame light beam X '.It is Transparence Display district R1 that transparent display 100 sends the region (region i.e. overlapped) of background frame light beam X ' with the first electrode pattern 138b.While background frame light beam X ' passes Transparence Display district R1, the illuminating bundle L of part also may pass through the region of display floater 120 and the first electrode pattern 138b overlapping and is converted to a display picture light beam L '.Consequently, it is possible to the Transparence Display district R1 of transparent display 100 just can show part display picture and the background frame of display floater 120 simultaneously.
On the other hand, when transparent display 100 is in a part of transparent part nontransparent display pattern, at least be created substantially absent potential difference between another the first electrode pattern 138c and the second electrode lay 139 so that with first electrode pattern 138c overlap another part polymer dispersed liquid crystal layer 136 in scattering states.The polymer dispersed liquid crystal layer 136 of another part in scattering states scatters the background light beam X of another part, to stop that the background light beam X of another part is transferred to display floater 120.Background light beam X be difficult to through region (i.e. with first electrode pattern 138c overlap region) be nontransparent viewing area R2.Being difficult under nontransparent viewing area R2 at background light beam X, the illuminating bundle L of another part may pass through the region of part display floater 120 and the first electrode pattern 138c overlapping and is converted to a display picture light beam L '.Consequently, it is possible to the nontransparent viewing area R2 of transparent display 100 just can show that the display picture of another part of display floater 120 is difficult to display background picture.
It should be noted that, the transparent display 100 of Fig. 1 is in addition to being operable in part transparent part nontransparent display pattern, and the demand of transparent display 100 also visual user switches to full frame display pattern or all-transparent display pattern.Following with Fig. 4 and Fig. 5, it is described.

Fig. 5 shows the situation when transparent display of Fig. 1 is in an all-transparent display pattern.When transparent display 100 is in an all-transparent display pattern, between the first electrode layer 138 and the second electrode lay 139, there is essentially a potential difference, all transparent states of polymer dispersed liquid crystal layer 136.Background light beam X is through the polymer dispersed liquid crystal layer 136 of transparent state, light guide plate 114 and display floater 120, and forms background frame light beam X '.While background light beam X forms background frame light beam X ' through all viewing area 120a of display floater 120, illuminating bundle L also may pass through all viewing area 120a of display floater 120 and is converted to a display picture light beam L '.Consequently, it is possible to all viewing areas of transparent display 100 just can be simultaneously in order to show display picture and the background frame of display floater 120.
Referring again to Fig. 1, in the present embodiment, the second electrode lay 139 can be divided into multiple second electrode pattern 139a.Second electrode pattern 139a can be with the first electrode pattern 138a substantial alignment.Can make under the principle that the polymer dispersed liquid crystal layer 136 of part switches between clear state, scattering states at the first electrode pattern 138a overlapped a mutually and second electrode pattern 139a, multiple second electrode pattern 139a are the most separated from one another and electrically independent, or are selectively electrically connected to same reference potential.

In the present embodiment, the second light guide plate 214 can pass through transparent optical cement 222 and is attached to the first optical microstructures of the first light guide plate 214 without on the 214e of setting area.Second optical microstructures 218 can pass through the second light guide plate 220 and is configured at the first optical microstructures of the first light guide plate 214 without on the 214e of setting area.In detail, in the present embodiment, the second optical microstructures 218 can be a processing structure of the second light guide plate 220 outer surface.Second optical microstructures 218 can be formed in one with the second light guide plate 220, and the second optical microstructures 218 and the second light guide plate 220 can be also secured to the first optical microstructures of the first light guide plate 214 without on the 214e of setting area.It should be noted that, the present invention does not limit the second optical microstructures 218 and the second light guide plate 220 must be fixed on the first optical microstructures of the first light guide plate 214 without on the 214e of setting area through transparent optical cement 222.In other embodiments, transparent display 200 also can omit transparent optical cement 222, and makes the structure that second optical microstructures the 218, second light guide plate 220 and the first light guide plate 214 be formed in one.
Second light guide plate 220 of the present embodiment has the one second exiting surface 220a towards the first bottom surface 214b, the second bottom surface 220b relative to the second exiting surface 220a and connects the second incidence surface 220c of the second exiting surface 220a and the second bottom surface 220b.Backlight module 210 further includes at least one secondary light source 224.Secondary light source 224 is in order to send the second illuminating bundle L2 (being plotted in Figure 10).Secondary light source 224 is configured at by the second incidence surface 220c of the second light guide plate 220.Second illuminating bundle L2 enters the second light guide plate 220 from the second incidence surface 220c and is left the second light guide plate 220 by the second exiting surface 220a.
It should be noted that the light transmission rate light transmission rate more than arbitrary first optical microstructures 216 of arbitrary second optical microstructures 218.In other words, the luminous reflectance of arbitrary first optical microstructures 216 is more than the luminous reflectance of arbitrary second optical microstructures 218.For example, in the present embodiment, the first the most multiple site of optical microstructures 216, and the second optical microstructures 218 is for example, directed away from multiple printing opacity protrusions protruding for a direction d of display floater 219.It should be noted that, the purpose arranging the first different optical microstructures 216 of light transmission rate and the second optical microstructures 218 on the first light guide plate 214 is: when transparent display 200 is in part transparent part nontransparent display pattern, the first optical microstructures 216 that luminous reflectance is higher can reflect the first more illuminating bundle L1, so that region display picture corresponding with the first optical microstructures 216 in transparent display 200 is better, more background light beam X can pass the second optical microstructures 218 that light transmission rate is higher, so that region display background picture corresponding with the second optical microstructures 218 in transparent display 200 is better.Therefore, the concrete structure of first optical microstructures the 216, second optical microstructures 218 is not limited to site and printing opacity protrusion, and the one high and one low two groups of optical microstructures of all light transmission rates are all in the category that first and second optical microstructures of the present invention to be protected.
Display floater 219 is configured on the first exiting surface 214a of the first light guide plate 214.Switching panel 230 and backlight module 210 are arranged at the same side of display floater 219.Furthermore, switching panel 230 and backlight module 210 may be disposed at the side near the background light source sending background light beam X.In the present embodiment, the first light guide plate 214 is configured in switching between panel 230 and display floater 219.But, the invention is not restricted to this, Fig. 9 is the generalized section of the transparent display of another embodiment of the present invention, refer to Fig. 9, transparent display 200A is similar to transparent display 200, thus like assembly represents with identical label, and in transparent display 200A, switching panel 230 is also configured between light guide plate 214 and display floater 219.
Referring again to Fig. 8, switching panel 230 overlaps with the second optical microstructures 218.Furthermore, in the present embodiment, switching panel 230 can expose the first optical microstructures 216, but the present invention is not limited.Switching panel 230 includes first substrate 232, the second substrate 234 relative to first substrate 232, the polymer dispersed liquid crystal layer 236 being configured between first substrate 232 and second substrate 234, the first electrode layer 238 being configured between first substrate 232 and polymer dispersed liquid crystal layer 236 and the second electrode lay 239 being configured between polymer dispersed liquid crystal layer 236 and second substrate 234.
In the present embodiment, the first electrode layer 238 can be divided into separated from one another and the most independent multiple first electrode pattern 238a.The second electrode lay 239 can be divided into multiple second electrode pattern 239a.Second electrode pattern 239a substantially can align with the first electrode pattern 238a.Multiple second electrode pattern 239a are the most separated from one another and electrically independent, or are the most all electrically connected to same reference potential.But, the invention is not restricted to this, in another embodiment, first electrode layer 238 and the second electrode lay 239 one of them can be divided into separated from one another and the most independent multiple electrode patterns, and another of the first electrode layer 238 and the second electrode lay 239 can be the full electrode of the above-mentioned multiple electrode patterns of comprehensive covering.In another embodiment, the first electrode layer 238 also can be two full electrode of the most comprehensive covering first substrate 232 and second substrate 234 with the second electrode lay 239.
As shown in Figure 8, when transparent display 200 is in a part of transparent part nontransparent display pattern, between the first electrode layer 238 and the second electrode lay 239, there is essentially a potential difference, so that the transparent state of at least part of polymer dispersed liquid crystal layer 236.Background light beam X may pass through part polymer dispersed liquid crystal layer 236, second optical microstructures 218 of transparent state and the first optical microstructures of the first light guide plate 214 without setting area 214e.From the first optical microstructures without the background light beam X of setting area 214e through the display floater 219 of part, and form a background frame light beam X ', so that region corresponding with the second optical microstructures 218 in transparent display 200 can display background picture.While region display background picture corresponding with the second optical microstructures 218 in transparent display 200, the first light source 212 can be opened to send the first illuminating bundle L1.First illuminating bundle L1 of part is guided by the first optical microstructures 216 and passes through the first optical microstructures setting area 214d of the first light guide plate 214.The first illuminating bundle L1 from the first optical microstructures setting area 214d passes the display floater 219 of another part, and form the first display picture light beam L1 ', so that region corresponding with the first optical microstructures 216 in transparent display 200 can show the part display picture of display floater 219.Consequently, it is possible to transparent display 200 just can reach subregion the display picture of display floater 219, the effect of subregion display background picture (i.e. the nontransparent display of part, partially transparent display).
It is worth mentioning and is, when transparent display 200 is in part transparent part nontransparent display pattern, in the present embodiment, secondary light source 224 can optionally turn off and not send the second illuminating bundle, to allow user be difficult to discover the existence of the second optical microstructures 218 at transparent display 200 and the second optical microstructures 218 corresponding position, and then promote the quality of background frame.In addition, owing to the luminous reflectance of the second optical microstructures 218 is low, if the first illuminating bundle L1 is transferred to the second optical microstructures 218, second optical microstructures 218 is difficult to guide a large amount of first illuminating bundle L1 to reach the first exiting surface 214a and goes out light, and makes the first illuminating bundle L1 be difficult to affect the quality of background frame.
The backlight module 210 of the present embodiment can farther include reflector plate 226.First light guide plate 214 is configured between reflector plate 226 and display floater 219.Reflector plate 226 covers the first optical microstructures setting area 214d of the first light guide plate 214 and exposes the first optical microstructures of the first light guide plate 214 without setting area 214e.In other words, reflector plate 226 covers the first optical microstructures 216 and exposes the second optical microstructures 218.Reflector plate 226 except the first light beam L1 leaving the first light guide plate 214 from the first bottom surface 214b can be led back in the first light guide plate 214 with recycling in addition to, reflector plate 226 can also stop the part background light beam X to the first optical microstructures setting area 214d transmission, so that background light beam X is difficult to affect the display image quality of display floater 219.Furthermore, secondary light source 224 can be hidden in reflector plate 226 times.If during consequently, it is possible to secondary light source 224 needs to open, the second light beam that secondary light source 224 sends the most does not enters the first optical microstructures setting area 214d, and affects the effect of display floater 219 display.
The backlight module 210 of the present embodiment can farther include blast sheet 228.Blast sheet 228 is configured between the first light guide plate 214 and display floater 219.Blast sheet 228 covers the first optical microstructures 216 and exposes the second optical microstructures 218.Blast sheet 228 can make the regional centralized more overlapped from the first illuminating bundle L1 of the first optical microstructures 216 to display floater 219 and the first optical microstructures 216, so that the first illuminating bundle L1 is difficult to the region (region i.e. overlapped in transparent display 200) being delivered in order to display background picture with the second optical microstructures 218.
Figure 10 shows the situation when transparent display of Fig. 8 is in a full frame display pattern.When transparent display 200 is in a full frame display pattern, it is created substantially absent a potential difference between the first electrode layer 238 and the second electrode lay 239, so that polymer dispersed liquid crystal layer 236 is in scattering states.Polymer dispersed liquid crystal layer 236 scattering background light beam in scattering states, to stop that the background light beam X of part passes the first optical microstructures of the first light guide plate 214 without setting area 214e and display floater 219.Additionally, in the present embodiment, reflector plate 226 can cover and not be switched the region that the polymer dispersed liquid crystal layer 236 of panel 230 is covered in the first light guide plate 214, therefore, when transparent display 200 is in full frame display pattern, user is difficult to perceive background frame from all viewing areas of transparent display 200.
On the other hand, when transparent display 200 is in full frame display pattern, the first light source 212 is opened to send the first illuminating bundle L1.First illuminating bundle L1 of part is guided by the first optical microstructures 216 and passes through the first optical microstructures setting area 214d of the first light guide plate 214.From the first illuminating bundle L1 of the first optical microstructures setting area 214d through display floater 219 partly, to form one first display picture light beam L1 '.The second illuminating bundle L2 is opened and sent to secondary light source 224.Second illuminating bundle L2 is guided and passes the first optical microstructures of second light guide plate the 220, first light guide plate 214 without setting area 214e and display floater 219 by the second optical microstructures 218, to be converted to the second display picture light beam L2 '.First display picture light beam L1 ' constitutes display full frame light beam with the second display picture light beam L2 ', and makes all viewing areas display full frame of transparent display 200.
The transparent display 200 of the present embodiment further includes the first light source controller 240 being electrically connected with the first light source 212 and the secondary light source controller 250 being electrically connected with secondary light source 224.When transparent display 200 is in full frame display pattern, the first illuminating bundle L1 that the first light source 212 sends has one first light intensity on the first exiting surface 214a of the first light guide plate 214.The second illuminating bundle L2 that secondary light source 224 sends has the second light intensity on the exiting surface 214a of the first light guide plate 214.If changeover module 230 the most fully stops background light beam X, the first optical microstructures through the second light guide plate 220 and the first light guide plate 214 can have the 3rd light intensity without the background light beam X of setting area 214e on the first exiting surface 214a of the first light guide plate 214.First light source controller 240 and secondary light source controller 250 can make the first light intensity be substantially equal to the summation of the second light intensity and the 3rd light intensity.Consequently, it is possible to when transparent display 200 is in full frame display pattern, backlight module 210 can have high outgoing light homogeneity, and then the full frame quality making transparent display 200 show is good.
It addition, the transparent display 200 of the present embodiment is optionally equipped with sets touch-control sensing assembly 260.Touch-control sensing assembly 260 may be provided on display floater 219 outer surface.Display floater 219 is configured between touch-control sensing assembly 260 and the first light guide plate 214.Touch-control sensing assembly 260 covers the first optical microstructures setting area 214d of the first light guide plate 214 and exposes the first optical microstructures of the first light guide plate 214 without setting area 214e.In other words, touch-control sensing assembly 260 covers the first optical microstructures 216 and exposes the second optical microstructures 218.Touch-control sensing assembly 260 can increase the convenience using transparent display 200.
Figure 11, Figure 12 and Figure 13 are the situation that the transparent display of Fig. 8 is applied to ball spring game machine (PACHINKO).The region R3 that refer to Fig. 8 and Figure 11, ball spring game machine P corresponds to the first optical microstructures setting area 214d of transparent display 200.The region R4 of ball spring game machine P corresponds to the first optical microstructures of transparent display 200 without setting area 214e.Many sub regions R41 of region R4 is multiple first electrode pattern 238a of the switching panel 230 corresponding respectively to transparent display 200.When the user of ball spring game machine P is intended to play, transparent display 200 can switch to part transparent part nontransparent display pattern.Now, a wherein region R3 corresponding to the first optical microstructures setting area 214d may utilize the picture that display floater 219 shows that user is liked, such as cartoon or adult's film, and the region R4 corresponding to the second optical microstructures 218 may be used to show the background frame being placed in transparent display 200 rear, such as game numbers runner.User can touch the touch-control sensing assembly 260 corresponding with another region R3, to proceed by game.
Refer to Fig. 8 and Figure 12, when game result produces, if user is won, then switching panel 230 the most independent available multiple first electrode pattern 238a make the game numbers background frame 666 being linked to be a pair linea angulata in game numbers runner pass display floater 219, and stop remaining game numbers background frame.Consequently, it is possible to user just can know clearly that it is won.Refer to Figure 10 and Figure 13, when there not being user operation ball spring game machine P, transparent display 200 can switch to full frame display pattern.Now, all region R3, the R4 showing picture of ball spring game machine P all utilize display floater 219 display to attract the picture of user, such as cartoon, adult's film, game rule or a combination thereof.It should be noted that, above-mentioned ball spring game machine is the one of which application mode of the transparent display of the present invention.The transparent display of the present invention is not limited to apply in ball spring game machine.The transparent display of the present invention also can be applicable to other suitable occasion.
In sum, in the transparent display of one embodiment of the invention, display floater rear is provided with backlight module and switching panel.Through at least one electrode layer of switching panel is designed as the most independent multiple electrode patterns, switching panel can have fringe area and bright zone simultaneously.Background light beam may pass through the switching bright zone of panel and the light guide plate of backlight module and is transferred to display floater, and then makes in transparent display the corresponding position, bright zone with switching panel can display background picture.On the other hand, background light beam can be switched the fringe area scattering of panel and be difficult to be transferred to display floater, thus may be used to the fringe area corresponding position switching panel in transparent display show that the picture of display floater is difficult to display background picture.In short, the electrode pattern that the transparent display of one embodiment of the invention passes through subregion can realize part Transparence Display, the effect of the nontransparent display of part.
In the transparent display of another embodiment of the present invention, the zones of different on backlight module light guide plate is provided with two groups of one high and one low optical microstructures of light transmission rate and the high a group optical microstructures rear of light transmission rate is configured with a switching panel.When transparent display is in part transparent part nontransparent display pattern, the switching at least part of region of panel switches to clear state, most background light beam may pass through switching panel and the high a group optical microstructures of light transmission rate of clear state, so that region corresponding to optical microstructures high with light transmission rate in transparent display can the good background frame of display quality.The same time, a group optical microstructures that light transmission rate is low can reflect the more illuminating bundle from backlight module, so that region corresponding to optical microstructures low with light transmission rate in transparent display can the picture of the good display floater of display quality.In brief, the transparent display of another embodiment of the present invention not only can realize part Transparence Display, the effect of the nontransparent display of part, is also with two groups of one high and one low optical microstructures of light transmission rate and makes Transparence Display district display background picture, nontransparent viewing area show the better of display floater picture.
