DETAILED DESCRIPTION OF THE INVENTION
Detailed description of present invention is as following:
Referring to FIGS. 1-3, which discloses a plate type image display device, which comprises: an imaging plate for projection, the imaging plate (100) comprising:
an impermeable plate (1) with a certain thickness defined a front surface and a rear surface corresponding to the front surface, wherein the front surface and the rear surface are in parallel;
a projecting device (2) disposed in said one surface of the plate (1) in a certain distance, wherein the projecting device (2) is capable of projecting light and image;
the plate (1) having a plurality of cylinder through holes (11) disposed on both surface thereof; wherein the cylinder through holes (11) are filled with transparent pillars (12), one end of said pillar (12) defined an input end (12a) which receives the light and image from the projecting device (2) and then guides them to an output end (12b) thereof; wherein an inner wall of the cylinder through holes (11) comprises a light reflective surface (13); wherein the both input end and output end of transparent pillar (12) are parallel to the rear and front surface of the plate.
Said projecting device (2) is a projector (21), the plate (1) looks just like a normal wall before using, when the projector (21) disposed behind the plate (1) is activated, the light (20) is projected to the rear surface of the plate (2), proceeded to the transparent pillar (12) of the through hole (11), and then guided to the front surface of the plate (1) to assemble a plurality of light spots and form the image, thus, the present invention is more like a hidden display screen, when the plate (1) is installed on the outside of the building or wall, the plate (1) becomes the surface layer of the building or wall, once the projecting device (2) starts projecting, the plate (1) soon becomes a commercial display board, the display effect of present invention would be better when using in the night.
The transparent pillar (12) is made of permeable plastic material such as Polyethylene, Polypropylene, and Polyvinyl Chloride, the production method of making said pillar (12) is to heat and melt said plastic material into liquid, and inject or press the liquid into cylinder through holes (11). Wherein the transparent pillar (12) is formed by heating plastic material to the liquid and pouring into the cylinder through hole (11) until the liquid plastic material is cooled down and become solid, the making method is simple, quick and cheap, thereby achieving reducing the plate price.
The both input end and output end of transparent pillar (12) are parallel to the rear and front surface of the plate, thereby achieving manufacturing easily and stacking the plate (1) conveniently.
The material of the pillar (12) can also use light permeable crystal transparent glass that has better light permeability and light guiding effect, but, whether the plastic or glass, both materials as the transparent pillar (12) have good water and vapor resistance.
As shown in FIG. 4, the inner wall of the cylinder through holes (11) comprises a light reflective surface (13), thus, when the light projected from the projecting device (2) enters into the transparent pillar (12), the light will be reflected by the reflective surface (13) and guided to the output end (12b) for displaying bright and concentrated light spot and avoiding, image distortion, furthermore, over 20000 holes are deployed on single unit area (ex: Length 1.5 m, width 2.5 m) of said plate (1), thus, plurality of light spots appear when said projecting device (2) is projecting light.
Said plate (1) is durable and widely applicable which is capable of using indoor and outdoor, when using outdoor, the quality of displayed image is stable and clear, and is being less affected by outrage weather, and defective pixel problem would not be occurred. Furthermore, the power consumption of present invention is only 6 ̃10% of conventional LED display, and complex maintenance procedure is not required for present invention, therefore, the deploying and maintenance cost of present invention is much lower than prior art.
As shown in FIG. 5, the imaging plate (100) is composed of one projecting device (2) and one plate (1), however, multiple plates (1) and projecting devices (2) could be applied for the demand of large scale screen.
As shown in FIGS. 6 and 7, present invention could also be applied on the building (200) or vehicle (300), and the size of said plate (1) is adjustable for user's need, when the display screen is assembled by multiple plates (1), there would be seamless in the connecting part, also match the original display ratio of the image projected from the display device (2), the brightness and display area of the plate (1) could also correspond to the size and brightness of the image projected by the display device (2) without affecting the appearance of the building (200) or vehicle (300), furthermore, the appearance of the plate (1) installed on the surface of the building (200) or vehicle (300) could involve in its appearance, and become a part of the structure of the building (200) or vehicle (300) instilled on.
The diameter of each said cylinder through hole (11) is 0.1 to 5 mm, which is adjustable for corresponding to the size of the original image from the projecting device (2).
The thickness of the plate (1) is 1 mm, if the thickness is below 1 mm, the quality of the image may be affected, however, if the thickness of the plate (1) is increased, although the image quality will not be affected, the increased weight for the plate (1) may cause moving and installed hardly.
Secondly, said plate (1) is made of metal or plastic, the polishing process could be applied if the plate (1) is made of metal, to upgrade the reflecting rate of the reflective surface (13), thus, a reflective wall is formed to guide the incident light from one to another side of the pillar (12), this method is convenient, fast, cost-low, and shorten the time of production effectively, furthermore, once the pillars (12) are injected, which are tightly attached on the wall of the cylinder holes (11), said reflective surface (13) achieve better protection which makes said reflective surface (13) become more durable from weathering and detaching.
Furthermore, the outside of said reflective surface (13) could be plated with a metal film (14), said metal film (14) could be formed by electroplating, dip plating, spray-coat plating or chemical plating, which are common skill of the field.
Referring to FIG. 9, the projecting device (2) defines a display screen (22), which discloses a large plate (1) combines with multiple display screens (22), the image of said display screens (22) is integrated by video splitter. The type is appropriate in the situation which needs to display large scale images, as description above, present invention is adaptive and convenient in different conditions and places.
The description above with figures of present invention is only the description of preferred embodiment but not the limit of present invention, modifications and variations made by person who has the skill in the field in the scope of present invention, might comprise the characteristic as claimed hereafter.
