Owing to the function of temporary stay of vision of human eyes, the utility model replaces the lattice LED luminescence matrix occupying large areas with the rows of LED luminotrons which are at high-speed parallel translation, thereby improving consistency of brightness, lowering manufacturing cost and overcoming defects of the projection equipment.
Description
One, technical field
The utility model relates to a kind of display screen, particularly a kind of parallel-moving type scanning luminotron display screen.
Two, background technology
The present situation of large-screen display equipment is mainly based on projection display and dot matrix LED display device.When projector equipment uses, between screen and projector, need certain depth space.Some difference of screen center's brightness and edge brightness adds diffusion of light, can influence sharpness, all is the reason that influences usable range, overcomes also relatively difficulty.
Dot matrix LED display screen then exists the bright consistance of pixel bad, and the blue pipe of expensive factors, especially super brightness price is higher, makes the full-color LED display screen be difficult to popularize.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model provides the parallel-moving type scanning luminotron display screen that a kind of display effect, reduction price, saving that is to improve display device more than two square metres taken up an area of the space, expanded range of application.
2, technical scheme: for achieving the above object, parallel-moving type scanning luminotron display screen described in the utility model is characterized in that it comprises framework, motor, main drive shaft, driven axle, locating shaft, scanning driving-belt, luminotron bar, control box axle and control box; Driven axle and locating shaft are supported on the framework by bearing abreast, the scanning driving-belt is installed on driven axle and the locating shaft, the luminotron bar is parallel, equally spaced be fixed on the scanning driving-belt, by motor-driven main drive shaft by bearings on framework, main drive shaft drives driven axle by belt and be provided with the control box axle between driven axle and locating shaft, this control box axle is supported on the framework by bearing, is provided with control box on the control box axle, and control box links to each other with light-emitting section by flexible cable.On the control box axle of a side, be provided with carbon brush, on the control box axle of opposite side, be provided with signal input collector ring, on framework, be provided with induction source, and on the luminotron bar of correspondence, be provided with synchronous inductor.Described luminotron bar comprises wiring board, light emitting diode, control Driver Circuit and signal input socket; Light emitting diode is arranged in the circuit board, and the control Driver Circuit that is connected with diode is fixed on the back side of wiring board.Be provided with gobo between adjacent luminotron bar, the luminotron bar is installed on the scanning driving-belt by red, green, blue three look compartment of terrains.
Principle of work of the present utility model is: framework is to fix and support motor and a series of belt pulley by 8 bearings in both sides, is again the structural member of suspension equipment.Motor drives main drive shaft by belt pulley, drives two driven axles in below by the belt pulley set that is fixed on both sides, drives the inboard two scan edge driving-belts of framework then, on the scanning driving-belt LED bars is installed.In frame mid portion the governor circuit case is housed, power supply is imported in the mode of sliding contact by collector ring on the control box axle and the carbon brush on the framework, and supply socket is fixed on the framework.The control circuit case rotates synchronously with the scanning driving-belt, and signal is received respectively on the luminotron bar by flexible cable.When LED bars passes through induction source, just obtain signal feedback and give governor circuit, so that governor circuit provides corresponding data according to the present position, make the picture accurate location.
According to the size of screen, select certain diameter, the light emitting diode of certain focusing angle is arranged, press pixel size at interval, directly to arrange and install in the circuit board, control Driver Circuit is also installed in the circuit board.Power supply and input plug signal, synchronous sensing device and securing member also must be installed on the wiring board.
The luminotron bar is fixed on the scanning driving-belt, and front and back are done vertical moving up and down, and when speed reached enough fast, visual inspection was a plane.Between the luminotron bar, gobo is housed during use, to intercept transmitted light behind.Can also show simultaneously by tow sides by circuit control.Both can be same picture, can be different pictures also, realizes the display effect of a machine two screens.
The collector ring of signal input is housed on the driven axle of a side, can imports R, G, B, the simulating signal of PC display card output, also can input video R, G, the B signal.
If the pixel that the pixel small luminous tube substitutes is just many, the pixel that pixel substitutes greatly is just few, otherwise brightness is not enough, and this just can determine to adopt the quantity of light-emitting section, has also determined the speed that the luminotron bar moves simultaneously.Have at least 24 luminotron bars inswept in certain zone by per second, just can avoid picture discontinuous.
Red, green, blue three-colour light-emitting pipe bar can also be mounted to monochromatic bar assembly respectively, be installed at interval on the scanning driving-belt again, light by the circuit timesharing, produce the cover chromatic effect that overlaps, the difficulty that one can avoid tri-color tube to overlap installs, two dwindle details in a play not acted out on stage, but told through dialogues interval time, overcome flicker.
3, beneficial effect: the utility model utilizes the persistence of vision function of human eye, the several rows of LED luminotron that high speed parallel is moved substitutes the some matrix LED luminous matrix that large tracts of land is arranged, both improve the consistance of brightness, reduced cost greatly, avoided the deficiency of projector equipment again.
