Abstract
The utility model relates to an optical flat board having optical directing element implementing frameless splicing to display screen, comprising a plurality of display screens, and characterized in that display screens are spliced to form a display plane, the display plane is equipped with the optical flat board, and an optical directing element with high density is disposed in the optical flat board, incident points disposed on the bottom surface of the optical directing element in the optical flat board corresponds with display points of the display screen, and exit points of the optical directing element disposed in the optical flat board are adjacent to each other and corresponds to incident points. The utility model is capable of eliminating frames formed when splicing display screens of small area to form display screen of large area. Conventional small area display boards smaller than 80 inches can be used for arbitrarily splicing to form entire display screen over 100 inches, and even 200 inches.
Description
Technical field
The utility model relates to a kind of optical flat, particularly a kind of optical flat that has the directed unit of light of display screen being realized no frame splicing.
Background technology
Present more than 80 inches whole large tracts of land LCD/PDP display technique need huge investment, and yield rate low, cost an arm and a leg.Greater than 80 inches whole LCD at present owing to can't popularize in the restriction of various aspects such as technology, equipment, starting material.Therefore common display screen with small size splices in the time need using large-area display screen, because display screen has frame, therefore has tangible splicing seams after splicing, has formed the black surround lattice on the large tracts of land display screen.Though the narrow limit LCD and the PDP display screen that aim at the splicing design are arranged now, have largely improved the tiled display effect, but still can't thoroughly eliminate the assembly frame.Then be subjected to the restriction of projector space, display brightness and luminance uniformity with other large-area digital projection.When using the projection joining method, piece overlapping with separate the display effect influence very big.And the piece integration technology costs an arm and a leg, and needs the accurate portrait distance of piecing together.Simultaneously, projection display apparatus needs higher source luminance, and its life-span is shorter, is generally less than 10,000 hours, not enough LCD CCFL backlight (cold-cathode fluorescence lamp) and 1/3rd of LED-backlit life-span.Large area LED digital display technique maximum to be limited in demonstration on the low side as number, the point of LED is apart from generally between 5 millimeters to 10 millimeters, display effect is not good.At present the smallest point of LED digital display technique is apart from being 3 millimeters, and display effect is improved, but every square metre need 111,111 of three-primary colours LED, and price, power consumption, heat radiation, life-span will become maximum bottleneck.
Summary of the invention
The purpose of this utility model is to solve the problem that can't eliminate frame when utilizing the small size display screen to carry out the splicing large area display screen in the prior art, and a kind of optical flat of display screen being realized no frame splicing is provided.A kind of optical flat of display screen being realized no frame splicing of the utility model design, comprise several display screens, it is characterized in that: display screen is spliced to form a display plane mutually, optical flat is arranged on display plane, in optical flat, be shaped on the directed unit of highdensity light, the incidence point of the directed first bottom surface of light that is positioned at optical flat is corresponding with the display dot on the display screen, and the directed first eye point of light that is positioned at optical flat is mutual adjacent and corresponding mutually with incidence point.Optical flat on display plane constitutes by some, every block of optical flat is corresponding with corresponding display screen, the incidence point of the directed first bottom surface of the light in every block of optical flat is corresponding with the display dot on the display screen, the directed first eye point of light that is positioned at optical flat is adjacent and corresponding mutually with incidence point mutually, and the edge of the eye point of the directed unit of the light in the optical flat is positioned on the optical flat sideline.The directed unit of light is taper, and the area of the eye point of the directed unit of the light in the optical flat is greater than the area of the incidence point of the directed unit of light of optical flat bottom surface.The utility model has the advantages that and to eliminate the frame of small size display screen when being spliced into the large tracts of land display screen.Can utilize existing ripe small size display board less than 80 inches, splice arbitrarily, expand out more than 100 inches, even surpass 200 inches entire display screen.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise several display screens 1 among the figure, 4 is the frame of display screen 1, it is characterized in that: display screen 1 is spliced to form a display plane mutually, optical flat 2 is arranged on display plane, in optical flat 2, be shaped on the directed unit 3 of highdensity light, the incidence point of directed first 3 bottom surfaces of light that is positioned at optical flat 2 is corresponding with the display dot on the display screen 1, and directed first 3 the eye point of light that is positioned at optical flat 2 is mutual adjacent and corresponding mutually with incidence point.Optical flat 2 on display plane constitutes by some, and every block of optical flat 2 is corresponding with corresponding display screen, and the edge of the eye point of the directed unit 3 of the light in the optical flat 2 is positioned on optical flat 2 sidelines.The directed unit 3 of light is taper, and the area of the eye point of the directed unit 3 of the light in the optical flat 2 is greater than the area of the incidence point of the directed unit 3 of light of optical flat 2 bottom surfaces.
During concrete the making, display screen 1 is spliced to form a display plane matrix mutually, place the big optical flat that is spliced by some blocks of optical flats 2 then in the above, generally in order to reach the effect of eliminating splicing frame 4, overlay optical flat 2 and the display screen 1 the same size that comprises frame 4 on the display screen 1, be the actual displayed face of actual displayed face greater than display screen 1, carry out processing such as photoetching at every block of optical flat 2, can select for use PMMA (polymethylmethacrylate) dull and stereotyped now as substrate, the directed unit 3 of light in optical flat 2 is taper, the area of the eye point of the directed unit 3 of light is greater than the area of the incidence point of the directed unit 3 of light, the incidence point of directed first 3 bottom surfaces of light that is positioned at optical flat 2 is corresponding with the display dot on the display screen 1, the edge of the eye point of the directed unit 3 of light is positioned on optical flat 2 sidelines, 2 realizations of adjacent optical plate are seamless spliced thus, and the display dot on the display screen 1 is shown enlarged on optical flat 2 surfaces.
