Embodiment
Fig. 1 a are the structural representations of the first embodiment of the display screen of the present invention.Display screen includes transparent plate 101, should
Transparent plate 101 includes first surface 101a.As shown in Figure 1 b, first surface 101a is up to for first surface 101a front view
Include two regions, the first area 102 less（Shown in FIG as the shape of maple leaf）With the second area 103.Display screen also includes steam
Generating means, the steam raising plant include vapour source 121 and pipeline 122, and wherein vapour source 121 produces steam and steams these
Vapour 151 is transported to the first surface 101a of transparent plate 101 by pipeline 122.First area 102 of first surface and the secondth area
103 surface properties are different, and steam 151 condenses to form fine droplet in the firstth area, and can not form fine droplet in the secondth area.
In the present embodiment, steam refers to vapor, can also actually use other steam, such as alcohol vapour
Deng.Steam in the present invention is not necessarily one-component, for instance it can be possible that the air that carry vapor is formed in the present invention
Signified steam.Steam has the characteristics of common, can exactly occur to condense phenomenon when meeting certain condition, become liquid by gaseous state
State.Such as the higher steam of temperature runs into the surface of the relatively low transparent plate of temperature and will liquefied.It is but not all
Liquefaction can all form small drop, condensation forms fine droplet and stills need to meet certain external factor, wherein main
Be steam condensation liquid and the surface to be depended on infiltration degree.If the surface of coagulating liq and transparent plate is soaked completely
Moisten, then the liquid can form a thin layer on transparent plate surface and can't form drop, if coagulating liq and transparent plate
Surface do not infiltrate completely, then steam be difficult its surface condense.
For example, transparent plate is glass, and the firstth area of its first surface does not make any processing, according to our daily
Experience it is known that, people breathe out against glass will form a piece of gauzy areas on glass, and this piece is vaporific on microcosmic
Region is made up of small water droplet one by one, therefore steam can form fine droplet in the firstth area.Simultaneously first
In secondth area on surface, hydrophilic coating is coated, such as simplest hydrophilic coating is exactly detergent.So steam is only in the firstth area
Condense and form fine droplet, liquid lamella is formed after second area's steam liquefied, so as to not form fine droplet.
Another example is that transparent plate is glass, and the firstth area of first surface is without any processing, and the secondth area then coats
Hydrophobic coating, such as grease or polymeric coating layer.So steam only condenses in the firstth area and forms fine droplet, difficult in the secondth area
To condense, therefore fine droplet can not be formed in the secondth area.
Certainly, it the above is only citing, be not construed as limiting the invention.In terms of preventing steam condensation from forming drop
Through there is many research, such as it is documented in《Colloid and polymer》The article of the 1st phase of volume 29 of periodical《Glass antifogging coating
Progress》This problem is explained with regard to comparison system, Chinese patent 101238187 and 102850924 is also right respectively in addition
This problem proposes solution.It can be seen that have very in terms of control steam condenses on some surface and forms droplet
Ripe technology, no longer does excessive description herein.
It is noted that in addition to glass, transparent plate can also be other sheet materials manufactured with transparent material, example
Such as acrylic board and lucite.Moreover, transparent plate is not necessarily hard, it is also possible to is flexible；Flexible flat board
Convenient manufacture, and printing technology can be used by coating print to flexible flat surface.Flexible flat can also be attached to just
The flat board of property（Such as glass；Flat board）Surface uses.Moreover, the firstth area of the first surface of transparent plate may also need to handle
To change its surface properties, such as to coat in firstth area on lucite surface some surfactant coatings right to adjust its
Steam condensation into liquid imbibition characteristic so that be more prone to droplet.In addition, air-flow removes caused by steam raising plant
Outside carrying steam, it is also possible to carry some small drops, this may cause the air-flow to seem in vaporific, similar to family expenses
Humidifier spray fog.Although these droplets being carried still can be inhaled without the physical process of condensation
It is attached to the firstth area of transparent plate while does not adsorb in the secondth area or exist in the secondth area not in the form of droplet, therefore reaches
The identical when effect and steam that arrive.Therefore steam raising plant also includes caused air-flow carrying fine droplet in the present invention
Situation, steam caused by same steam raising plant in the present invention should also do more wide in range understanding, both include
Gaseous steam, also include the air-flow in vaporific carrying droplet.
In the present embodiment, in the firstth area formed with fine droplet so as on the whole seem with light scattering characteristic without
It is transparent again, and there is no the presence of fine droplet in the secondth area thus keep transparent plate transparent characteristic in itself, thus can be with
The profile in the firstth area and the secondth area is shown.When need not show, it can stop conveying steam to first surface
Or the amount of the steam of conveying is reduced, so droplet in the firstth area can be evaporated gradually so that the firstth area recovers again
Bright state, pattern is no longer presented on whole transparent plate.
In the present embodiment, the firstth area is pattern area, and its maple leaf pattern part is no longer transparent.In fact, can also anti-mistake
Come, the secondth area is pattern area, i.e., maple leaf drafting department is divided into transparent, and other parts are the firstth opaque area, so equally may be used
So that the pattern of maple leaf is presented.
In the present embodiment, a citing of the structure of steam raising plant is as shown in Figure 2.Steam raising plant includes containing
There are the liquid bath 221 and air-blast device 226 of liquid, air-blast device 226 passes through the Air blowing of the top of liquid tank liquid 224
Pipeline 222 is transported to the first surface of transparent plate.The wind 231 that air-blast device 226 is blown out does not carry steam or only carried few
Measure steam, into the top of liquid 224 after become air-flow 232, the air-flow 232 carries the steam that liquid 224 is evaporated to above it,
The air-flow 232 forms air-flow 233 after the output of piping 222.Air-flow 233 is incident in the first of transparent plate with a large amount of steam
Surface, steam will form fine droplet in the firstth area of first surface.
Preferably, steam raising plant also includes temperature control device 223, for controlling the temperature of liquid tank liquid 224.Temperature
Higher, the saturated vapor pressure of liquid 224 is bigger, i.e., the steam entrained by air-flow 233 is more.Need to control steam in air-flow 233
Amount, it is too low, droplet can not be effectively formed, too high, may make that the droplet in the firstth area grows is excessive so as to being formed
Liquid pearl and can not stablize rest on transparent plate surface.It is entrained in air-flow 233 by controlling temperature control device 223 to control
Steam number so that the droplet in the firstth area keeps stable to a certain extent.
In the above-described embodiments, transparent plate 101 is in open environment, such steam 151 be transported to its first
Not necessarily it is completely used for forming fine droplet behind surface, but has part to disperse in open environment, and is formed in the firstth area
Fine droplet be not easy to keep stable, but easily volatilized into environment.Then solved in next embodiment of the present invention
This problem.The structural representation of the display screen of next embodiment is as shown in Figure 3 a.
The difference of the embodiment and above example is, in addition to transparent plate 301, in addition to the second flat board 311, should
Second flat board 311 be arranged in parallel with transparent plate 301 and has gap, and the first surface 301a faces of transparent plate between the two
To second flat board 311；Steam 351 caused by steam raising plant is transported into the gap between two flat boards, and steams
Vapour can not form fine droplet on the surface towards transparent plate of the second flat board.So, vapor stream 351 will be in gap
Without dispersing in the environment, this is advantageous to the formation in the fine droplet in the firstth area for transmission.Because steam is in the second flat board
Fine droplet can not be formed towards the surface of transparent plate, therefore the second flat board is without interference with the presentation of the image of transparent plate.
Preferably, the edge of the second flat board 311 and transparent plate 301 is sealed together, and Fig. 3 b show transparent plate
（Second flat board）Front view.It can be seen that the second flat board 311 is connected simultaneously with the edge encapsulant 312 of transparent plate 301
Sealing, while include air inlet 313 and gas outlet 315 on the encapsulant at edge, steam 351 is flat from air inlet into second
Gap between plate and transparent plate and flow out the gap from gas outlet and form air-flow 352.Second flat board 311 and transparent plate
301 edge seal helps to prevent steam from the random diffusion in edge, and it causes air-flow in gap and humidity to keep stable,
This contributes to the formation of stable fine droplet.Certainly, there is certain requirement the position of air inlet 313 and gas outlet 315, such as
Can not from it is too near, otherwise it cannot be guaranteed that vapor stream can be full of each corner in gap.And air inlet in the present embodiment
Mouth 313 and gas outlet 315 are located at diagonal position, and this is only citing without being construed as limiting.
It is noted that more visual effects can also be realized using Fig. 3 a structure.For example, the second flat board is also
Another piece of transparent plate, also include the firstth area and the secondth area on the surface on the right side of the second flat board 311, while control steam generation
Steam 351 is also input in the right lateral surface of the second flat board caused by device, and forms fine droplet simultaneously in the firstth area
Fine droplet is not formed in the secondth area.Such to be advantageous in that, the pattern in the firstth area can be with transparent plate 301 on the second flat board
The pattern in upper firstth area is different, can essentially so realize that the alternating of two width patterns is shown.It is exactly specifically if desired to show
Show the pattern on transparent plate 301, just control steam raising plant that steam 351 is transported between transparent plate and the second flat board
Gap in, while steam is not transported in the right lateral surface of the second flat board, thus can be only on display transparent plate 301
Pattern；If desired the pattern in the firstth area on the second flat board is shown, then controls steam raising plant that steam 351 is transported into second
The right lateral surface of flat board, while steam is not transported to the gap between two pieces of flat boards, thus can be only on the second flat board of display
Pattern.Certainly in actual applications, such method can also be applied to realize that the alternating of multiple patterns is shown, this need by
Placement that multiple transparent plates are parallel to each other and the flow direction for controlling steam raising plant conveying steam.Actually control the stream of steam
To easily realizing, such as same steam raising plant has multiple pipeline output gas flows, the corresponding stream of each pipeline
To as long as controlling the opening and closing can of each pipeline to control the flow direction of air-flow.More directly, more steamings can also be used
Vapour generating means controls the flow direction of each steam respectively.
In the embodiment shown in Fig. 3 a and Fig. 3 b, the first surface solved in transparent plate forms stable steam gas
The problem of stream, while also limit volatilization of the fine droplet into environment, and the of protection transparent plate is also acted simultaneously
The effect on one surface.It is exactly in actual use, with using steam generation but this embodiment still suffers from a problem
The amount of liquid in device can be fewer and fewer, and this just needs artificial adding liquid, brings certain inconvenience.With reference to figure
4 embodiment illustrates to this way to solve the problem.
Fig. 4 is the structural representation that the present invention has one embodiment.The difference of it and the embodiment shown in Fig. 3 b is, enters
Gas port 413 is connected and closed with the outside of transparent plate in the second flat board with gas outlet 415.Air-flow flows through liquid 424
The gap that top carries steam and flowed into by air inlet 413 between transparent plate and the second flat board forms air-flow 451, is flowing through
Become air-flow 452 after first surface, air-flow 452 returns to the top of liquid 424 by gas outlet 415.So, whole system is formed
One inner loop, the purposes of air-flow are that the steam above holding liquid can be identical with the vapor pressure in gap, air-flow
It may be by what a built-in fan was formed.Due to not with ft connection, liquid and steam all without reduction, because
This need not continuous artificial adding liquid.
Certainly, temperature control device can also be included to control the temperature of liquid 424 in the present embodiment, such as reduce liquid
424 temperature passes through gas to reduce the vapour pressure above liquid and gradually eliminate the fine droplet in the area of first surface first
These fine droplets are reclaimed liquid return trough by stream.
In the embodiment shown in Fig. 3 a and 3b, an air inlet and a gas outlet are only included.When producing image, lean on
The firstth area on the position of nearly air inlet first produces droplet, then away from air inlet（Close to gas outlet）Position on produce again
Droplet；During picture drop-out is made, the droplet on the position of air inlet first disappears, away from air inlet（Close to go out
Gas port）Position on droplet after disappear.This creates the terminal the fade effect of image.Can certainly include two groups or with
On air inlet and gas outlet, with the use of different image morphing effects can be produced.Two groups or more of air inlet and go out
Gas port can also be applied and following embodiments.
In the above embodiments, transparent plate is all transparent that this is applied to the occasions such as showcase and carries out image
Display.The surface relative with first surface of actually transparent plate can also plate reflectance coating, thus be suitable for use with mirror
To carry out the display of image.As a same reason, in the embodiment shown in Fig. 3 a, the second flat board is also made up of transparent material, and/or
There is reflectivity in the second flat board face parallel with transparent plate.
In the above embodiments, the image information that first surface is presented is only limitted to the profile in the firstth area and the secondth area,
The image presented only has appearance information, without half-tone information.The following examples then solve this problem.
In order that half-tone information is presented, it is necessary to by the interlaced arrangement in the firstth area and the secondth area on microcosmic, so in image
In a small part（Such as in the range of 1mmx1mm）, the ratio of the area in the area in the firstth area and the secondth area, just determine this
The individual small gray scale locally seemed.For example, in a small part, Fig. 5 a illustrate the distribution in the firstth area and the secondth area, wherein
Dash area is the firstth area and remainder is the secondth area.It can be seen that now the firstth area account for most area, this part is seen
Get up to be almost full with fine droplet, it is substantially opaque so as to seem that light scattering effect is very strong.And in a phase in Fig. 5 b
With in the subrange of size, the firstth area（Dash area）Area ratio be decreased obviously, so this region seems only have
Partial dispersion effect, its dispersion effect want much weaker than Fig. 5 a, while seem to want much transparent.Therefore, the office shown in Fig. 5 a
Portion and the part shown in Fig. 5 b seem just to be provided with different gradation of images.Therefore, the firstth area is made up of many minute cells,
Separated between unit by the secondth area, such steam condenses to form at least one drop in each cell surface, can be with
Image is controlled in the gray scale of this position by controlling the area ratio in the firstth area and the secondth area.
In order to realize enough gray scales, such as 256 grades of GTGs, it is necessary to realize 256 kinds in a small subrange
The dutycycle in the firstth area of consecutive variations, this requires that the minute cells in the firstth area are sufficiently small, such as reaches 300DPI resolution
It is more than rate.This can be realized using existing printing machine, i.e., using printing machine by some special materials（Such as above-mentioned wash
Wash agent）The firstth area or the second area surface are printed onto so that it possesses required surface characteristic.In addition to printing machine, it can also make
The method exposed under mask realizes that small pattern makes.This is all existing technique, is not repeated herein.
The area ratio in the firstth different areas and the secondth area is realized, the shape of the change each minute cells in the firstth area can also be passed through
The method of shape, such as shown in Figure 5 c, each minute cells in the firstth area are rounded, and the area ratio in the firstth area has compared with Fig. 5 a
Declined.As fig 5d, each minute cells in the firstth area can also be in bar shaped.It is appreciated that first shown in Fig. 5 a to 5d
The shape of the minute cells in area is simply illustrated, and is not construed as limiting.
When the firstth area is complete a piece of, the fine droplet of adjacent condensation easily attracts each other so as to be combined into one
Big drop, this can cause the unstable of drop because drop it is big to a certain extent when will be difficult due to gravity
With in superficial residence.And in the present embodiment, first divides between multiple minute cells and each unit and is separated out by second, this
Another benefit is brought while solving the problems, such as gray scale, is exactly that drop between minute cells will not be combined with each other, this has
Beneficial to the stability of image.To reach this effect, it is preferred that the second area surface does not infiltrate to drop.
In the above embodiments, all it is so as to realizing by the light effect difference in the firstth area and the secondth area of transparent plate
The display of pattern, it can also actually make display effect more preferable.
Fig. 6 a be the present invention display screen next embodiment in transparent plate front view.With embodiment above not
Also include the light source 641 for being arranged at least one edge of transparent plate with, the display screen, the light 691 that light source is sent is from saturating
The marginal incident of bright flat board 601 is in the inside of transparent plate 601 and propagates wherein.The display screen that Fig. 6 b are shown then includes phase
To two light sources, the two light sources respectively positioned at transparent plate relative two edge and by light from marginal incident in saturating
The inside of bright flat board.Both of which shown in Fig. 6 a and Fig. 6 b is citing, and the lower edges of certain display screen can also be set
Light source is put, does not do repeat specification herein.
Fig. 7 illustrates the propagation schematic diagram of light that light source in the present embodiment is sent in transparent plate.Transparent plate 701
First surface be 701a, have three fine droplets in the firstth area on first surface, drop 709 is one of them.From transparent
The light 791 and 792 of side incidence on the left of flat board can be totally reflected after the inner surface of transparent plate is incided, therefore it
Can in transparent plate internal communication.When they are incident on droplet in the air, total reflection condition is destroyed so as to be able to
Go out to shoot out.Such as light 791 is incided and is emitted on droplet 709, the droplet that light 792 is incident in centre is gone out
Penetrate, and enter light 793 from right side and be also incident in droplet 709 so as to be emitted.It can be seen that the light of three citings is all
From first surface 701a outgoing, this explanation light is mainly emitted from this face；And in practice, also there is some scattered light from
The back side outgoing on one surface, the light intensity of this some scattered light are less than the light intensity of the light from first surface outgoing.It is appreciated that
One area's light can be emitted, and being still met in second area's light total reflection condition therefore can not be emitted, and so allow for the
The pattern in one area is emitted in the form of light, it appears that visual effect is more preferable.
With reference to Fig. 5 a to Fig. 5 d, when the area accounting in the firstth area is larger, then the emergent light herein being readily appreciated that is just relatively strong,
Luminous intensity and the area accounting in the firstth area are proportional.Therefore the area accounting can in one small the firstth local area of control is realized
Go out the control of luminous intensity to this part, that is, realize the gray scale of display image.
In the present embodiment, because droplet destroys the total reflection of light so that light is led from the place for having droplet
Out realize luminous Image texture.Actual glazed thread can not also be incident from the side of display screen.As shown in Figure 10, light source
1041 face transparent plates 1001, the light 1091 that light source is sent are incident in display screen.Incident light can be by fine droplet in the firstth area
Scattering, some scattered light continue forward（For to the left in figure）Propagate and form scattering light 1093, some scattered light is reflected back toward
To form scattering light 1092；Incident light can be transmitted directly in the secondth area simultaneously, therefore in the exit direction of scattering light 1092 only
The scattering light in the firstth area can be seen, so as to realize the display of image, and in the exit direction of scattering light 1093, the firstth area dissipates
The transmitted light for penetrating light and the secondth area seems that effect is also different so that human eye can be distinguished, and can also so realize image
Presentation.
Further, the firstth area covers the whole first surface of transparent plate 1001 on the whole, and the secondth area is not present
Or the secondth area as Fig. 5 a is only located at each unit between each minute cells in the firstth area being used to separate the firstth area so that coagulating
Excessive drop will not be mutually merged into first area's droplet by tying.Obviously, on such display screen and do not have an image information.
Meanwhile light source 1041 is a projector, the light that it sends carries image information, and the light 1091 of the carrying image information is shown
Screen scattering, part, which continues to propagate forward, forms image light 1093, and part reflects to form image light 1092.Now, show
Screen is only equivalent to scatter the effect of screen.
In next embodiment of the present invention, as shown in figure 8, display screen also includes control device 823 and detection device
824, detection device 824 is used to detect the environment temperature and/or humidity near transparent plate, and control device 823 fills according to detection
Running parameter and the working time of the data control steam raising plant that 824 detections obtain are put, such as controls steam raising plant
The temperature of middle liquid or the temperature of steam, control the flow velocity of neat air-flow, control opening and closing of steam raising plant etc..
Why the data of environment temperature and humidity need, and are because this is all important for the stability for forming droplet and droplet
Data.And these data application methods and the running parameter and the working time that how to control steam raising plant, this can be with
Calculated using the condensation theory in physical chemistry, and more directly, it is by advance experiment, draws in different environment
In order to realize stable fine droplet, it is necessary to which steam raising plant has which type of running parameter and work under temperature and humidity
Time, by these data storages in control device 823, the data then obtained in practice according to detection device 824 are found
The control method of suitable steam raising plant.
In the embodiment above, the image shown by display screen be do not have it is coloured, the present invention next embodiment
In will solve this problem.
The structural representation of another embodiment of the display screen of the present invention is shown in Fig. 9.Wherein, transparent plate 901,
902 and 903 all have the first surface of oneself respectively, have respective firstth area and second respectively again on respective first surface
Area, the technology of each transparent plate can use the technical scheme of foregoing each embodiment, not do herein multiple completely
It is multiple.In the present embodiment, the direction of the first surface of three transparent plates is identical, is all located at their right sides in figure.Due to
Light is mainly to be emitted from the first surface of transparent plate, therefore the main light emission direction so on these three transparent plates is identical
's.Display screen also includes fourth panel 904, between transparent plate 901 and 902, between transparent plate 902 and 903, transparent plate
Gap all be present between 903 and fourth panel 904, these three gaps have identical effect with the gap in Fig. 3 a.This four pieces
The edge of flat board 901 ~ 904 is sealed by a seal closure 912, and an air inlet, steam hair are left on seal closure 912
Three gaps that steam caused by generating apparatus 921 is entered between this four pieces of flat boards 901 ~ 904 by air inlet, and respectively each
Fine droplet is formed in firstth area of bright flat board.Certainly, it is readily appreciated that, three tunnels of a steam raising plant point can also be used
Steam is conveyed to three gaps respectively, it might even be possible to steam is conveyed to three gaps respectively using three steam raising plants, this
Belong to protection scope of the present invention.It is appreciated that the steam in embodiment described in Fig. 3 b and Fig. 4 is inside and outside flat board gap
The type of flow, can equally be used in the present embodiment, be not repeated to illustrate herein.
At least one edge of transparent plate 901,902 and 903 sets the light source of red, green and blueness, light source respectively
The light sent enters inside transparent plate and in its internal communication from the side of each transparent plate.So, transparent plate 901,902
With 903 in respective firstth area will send the light of red, green and blueness respectively, and these three transparent plates stack just
So that its light sent stacks and is collectively forming a coloured image.Wherein, red, green, blueness might not have
Sequentially, and because the light sent on leftmost transparent plate 901 needs to cause by the scattering of transparent plate 902 and 903
Brightness declines, it is therefore preferred that the color that required brightness is minimum, such as blueness can be used on transparent plate 901；Simultaneously
The light that transparent plate 902 is sent needs to cause brightness to decline by the scattering of transparent plate 903, it is therefore preferred that transparent flat
Red light source is used on plate 902, and required brightness highest color i.e. green is used on transparent plate 903.
Therefore for a specific multicolour pattern, red, blueness, green three sub-patterns are first decomposed into, then distinguish
These three sub-patterns are realized with the firstth area on the first surface of three transparent plates, then are made on the transparent plate of each sub-pattern
Illuminated with the light source of respective color, coloured image is presented in the display screen can.
Certainly red, blue, green is a kind of citing of three primary colours herein, can also actually use other three bases
Color, such as cyan, yellow and aubergine, as long as the light that the light source of these three colors is sent mixes to form white light.
In the present embodiment, the surface towards transparent plate 901 of transparent plate 902,903 and fourth panel is in steam
Fine droplet will not be formed, such as coated with hydrophilic coating.The formation of droplet can so be prevented and hinder light just
Often propagate.In addition, the surface relative with its first surface of transparent plate 901 can be coated with reflectance coating, or in fourth panel
One of two surfaces can be coated with reflectance coating, so when steam raising plant does not produce steam display screen be mirror rather than
Transparent.
In fact, in addition to the display for realizing coloured image, another application can also be realized using Fig. 9 structure, just
It is that the alternatings of more images shows that this had done explanation in previously mentioned Fig. 3 a structure, further combined Fig. 9 herein
Structure illustrate.Specifically, the first zone on three transparent plates 901,902,903 has different image informations,
