Abstract

The display screen is composed of three primaries light source of R, G and B added with colour primaries light source, electrical controlled crossbar shelter, mixed colour cavity corresponded by light window after glow colour plated film which is very sensitive to colour light. It can be made in any geometric size including the bucking with out limitation for superthin wall hung with high cleaness. The unit display area of it is much raised as that of larger than liquid crystal display and electric beam display tube.

Description

Light-scanning color image display screen (device)

Light-scanning color image display screen (device) is to substitute the electron beam picture tube, and it is by automatically controlled shutter, mixed light chamber, three primary colors light source, primary light source and the electric electrooptic modulator that causes luminous effect etc. constitute in length and breadth.Its principle is: the three primary colors light source is subjected to R on TV or the display circuit, G, (R is a ruddiness in the control respectively of B signal, G is a green glow, B is a blue streak), the luminous intensity of modulating primaries and primary lights respectively by electrooptic modulator (in the schematic diagram 6), mixed light after the modulation is in the mixed light chamber behind the mixed light, mirror surface through the mixed light chamber, the even automatically controlled shutter of directive, automatically controlled shutter has bilayer, one deck is vertical (vertically), one deck is horizontal (level), the double-deck intersection mutually is close together, automatically controlled shutter is to cause the optical chopper that luminous effect is made according to electricity, its double-layer structure is to be carved with many grooves on transparent material, be filled with the material that electricity causes luminous effect in the groove, be coated with conductive layer (Figure 1A) as the direction vertical with screen on (Figure 1B) trough rims such as nitrobenzene, the inboard parallel one side with screen of groove studs with C among three primary colors fluorescent film Fig. 1.The conductive layer of this two-layer automatically controlled shutter is limited by row field signal, and their printing opacity light tight (promptly opening and closing) is controlled by a row stepped-up voltage, and its scanning process is:

Making alive (voltage at once) successively from top to bottom on all conducting films of the automatically controlled shutter of level (horizontal shutter) makes the automatically controlled shutter of level that one page window printing opacity be arranged successively from top to bottom.On vertical (vertical shutter) all conducting films of automatically controlled shutter from left to right or right-to-left making alive (being field voltage) successively, make vertical automatically controlled shutter that one page window printing opacity be arranged, two-layer cross lamination together, on screen, has only a luminous point printing opacity, when first page of printing opacity of the automatically controlled shutter of level, vertical automatically controlled shutter is printing opacity from left to right successively, just have only a diaphanous spot (pixel) moving in screen the place ahead like this, be expert in the cycle of sweeping, having delegation's light pixel shows, and the like, second row, the third line ... the same, from finishing the scanning of light, the principle of scanning is the same from left to right under the action of a magnetic field to be similar to electron beam in the kinescope, shows thereby finish entire image.

Automatically controlled shutter electrode control signal comes from field or row image scanning control signal, the mixed light chamber is a corresponding attached chamber with automatically controlled shutter, its task is a primaries and primary lights colour mixture within it, though different irrelevant the disturbing of optical source wavelength, but the optical cavity task be three color scheme system light within it portion finish all light all uniformly automatically controlled shutter of directive such as schematic diagram 6, three-color light source is made of red green blue streak source, the light that they send is regulated and control its intensity by electrooptic modulation, its polarizer is set in the electrooptic modulator, and its control signal comes from R, G, the B circuit.

Annotate: the Arabic numerals 1 expression screen in the Figure of description, in the schematic diagram, 2, automatically controlled shutter, 3,4,5, the three primary colors light source, 6, electrooptic modulator, 7, the mixed light chamber, 8, mirror surface.Fig. 1 is automatically controlled hundred windows of level (horizontal stroke) (vertical [indulging] automatically controlled shutters and the same only vertical cutting of horizontal windows structure), and Fig. 2 is display screen screen figure, and Fig. 2 D is the automatically controlled shutter of level, and Fig. 2 G is vertical automatically controlled shutter.

Claims

1, light-scanning color image display screen, its feature: it utilizes three primary colors light source and primary light source under electrooptic modulator is transferred, and image pixel is carried out the pointwise mixed light make the imaging of mixed light picture element scan under the orderly keying of automatically controlled shutter on screen in length and breadth.

2,1. described according to claim: it is characterized in that automatically controlled shutter bilayer intersects at row field signal control down mutually, respectively have in length and breadth one page window successively high-speed opening and closing make the imaging of mixed light picture element scan.

3,1. described according to claim: it is characterized in that red green orchid (R, G, B) primaries and luminous intensity that primary lights send are modulated by R, G, the B signal of telecommunication, modulate back mixed light even automatically controlled shutter of directive on the mixed light cavity wall.

4,1. described according to claim: the parallel twilight sunset point fluorescent film of light directive that it is characterized in that entering automatically controlled shutter groove with screen.
