In the big screen display device that provides according to the utility model based on fiber optic conduction; described S*T bar optical fiber in each basic display unit is drawn the back from each pin and is become cone to draw in; pass the through hole on the basic display unit support; the tapered optical fiber part of wherein passing before the through hole is covered by the taper protective cover, and the protected sleeve pipe of tapered optical fiber part that passes behind the through hole entangles.
The big screen display device that enforcement provides according to the utility model based on fiber optic conduction, have simple in structure, cheap, can realize 32 true color, the display effect that contrast is adjustable, have characteristics such as dynamic display effect is good simultaneously, can be by computer and E-mail Long-distance Control, and need not special-purpose hardware and software.The image that all computer display screens can show, it can both dynamically show under the situation that display size is exaggerated.To have an optical loss little with existing projection display screen ratio for it, the brightness height, need not too big space length, also have life-span length, good weatherability, advantage that failure rate is extremely low, securities market, bank, supermarket, traffic, culture and sports shop institute, the public propagate the large colour display screen of high-quality low-cost of the best in place at present.
Description of drawings
Fig. 1 is the structural representation of the utility model based on the big screen display device of fiber optic conduction.
Fig. 2 is the structural representation of a basic display unit in the key diagram 1.
Embodiment
As shown in Figure 1, in the embodiment of the utility model based on the big screen display device of fiber optic conduction, comprise one as the computer-projector machine 5 of display light source and the large tracts of land display screen by 5 row (1.....5), 10 row (A, B, ... J) 10*5 is that 50 basic display units 1 are formed altogether, wherein A1 represents the unit of A row, the 1st row, and D3 represents that D is listed as the unit of the 3rd row, and the like.Like this, 50 unit (module) that can arrange by two dimension realize that large-sized solor dynamically shows.Wherein, 50 basic display units 1 are contained on the support 2,50 basic display units, the 1 corresponding bundle optical fiber of 5 row, 10 row is concentrated into projection screen 4,5 brightness of adjusting projector reach the distance with projection screen 4, and the image that projector's 5 projections can be gone out is presented on the giant-screen of being made up of 50 basic display units 1 by fiber optic conduction.
Each basic display unit 1 among Fig. 1 as shown in Figure 2, each basic display unit comprises that the surface is 24*24 (24 row, 24 row, also can be that other are selected) the plastic cement picture screen 12 of individual spherical convex surface, therein 24*24 spherical convex surface 6 inboards with it correspondence be provided with 24*24 pin 7, the periphery of each pin 7 is coated with reflector layer.The end that 24*24 bar optical fiber 10 arranged simultaneously is connected to the inboard of corresponding spherical convex surface 6 respectively by pin 7, the other end then is arranged in the rectangle end face according to the order of sequence and constitutes a projection screen part.Pin 7 in each basic display unit 1 and the high transparent adhesive tape fusion one of insertion optical fiber 10 therebetween by low-loss index of refraction 〉=1.5.Each is drawn the back from each pin and becomes cone to draw in; pass the through hole on the basic display unit support 9; wherein pass the taper protective cover 8 that the tapered optical fiber before the through hole partly is installed on the support 9 and cover, the protected sleeve pipe 11 of fiber section that passes the collimated beam behind the through hole entangles.Projection screen 4 of the present utility model (Fig. 1) is made up of the light source input end face of several basic display units 1, because the quantity of basic display unit and the difference of arrangement, it can constitute the screen of various ways, different size.
Plastic cement picture screen 12 in the basic display unit 1 uses the weatherability spy to spend the high PC plastics injection of lightness well and forms, the front has 24 * 24 dot matrix to be arranged in spherical spherical convex surface 6, constitute picture element with amplification and scattering, thereafter the pin 7 through the coating reflection horizon that has cone is to reduce the luminous energy loss, to strengthen picture element brightness.The optical fiber afterbody inserts in corresponding each pin 7 of spherical male face, and the high transparent glue through index of refraction 〉=1.5 is bonded as one, thereby reduces the loss between the optical fiber transfer surface to greatest extent.Each plastic optical fiber head is by 24 * 24 arranged and corresponding with display screen, and the blended rubber cementation forms projection screen 4, throws the color image of coming to receive by computer-projector machine 5.Protective cover 8, support 9 and the protective sleeve 11 of protection and fixation have been provided with for the protection plastic optical fiber.With some basic display unit combinations, constitute entire display screen.Its principle of work is, to be projected to by the image that computer or E-mail transmit on the projection screen of forming by each basic display unit light input end face 4 by computer-projector machine 5, pass to display screen by way of optic module group 3 losslessly, because projection screen 4 is one to one with the picture element of display screen, and by the every loss-free transmission of optical fiber, therefore identical on the shown image of display screen and the map architecture on the projection screen 4, just the true size because of projection screen and display area of the size of image is than having increased tens of times.
Install and make method, the basic thought that the utility model adopts plastic optical fiber to make colored large-screen is to adopt several basic display units of two-dimensional arrangements to form.The display area of each basic display unit can be 12cm * 12cm.Can be combined into various different sizes by the dot matrix aligning method according to customer requirements, various difform screens, each display unit is located by connecting on support with the bolt type rivet.The projection screen of each display unit is corresponding with display screen, become projection screen by the dot matrix permutation and combination, be fixed on the support.The computer-projector machine is installed on certain distance at last, and start debugging focal length, brightness, color, contrast make clear image, and color is plentiful.Image money section with needs during use passes through computer, and E-mail reaches the computer-projector machine, can broadcast.From the above mentioned the two point battle array arrange by the colored large-size screen monitors display screen of plastic optical fiber for light matchmaker conduction.The front has the spherical of amplification and scattering function, thereafter the high brightness picture element that has the reflection horizon through applying of cone, the high transparent adhesive tape of the low-loss index of refraction of use from the above mentioned 〉=1.5 with optical fiber and display screen bonding be an integral body, reduce the loss between the optical fiber transfer surface to greatest extent.
