Abstract
The super-large screen displaying board is a transparent board with square cylindrical lenses on one side and isosceles triangular prisms and light-absorptive black partition for avoiding reflection of ambient light on the other side. The cylindrical lens aligns with the margin of each pixel for eliminating the joint seam and dark region between pixels. The triangular prism is perpendicularly positioned to reflect the ambient light from top to bottom or left right for improving contrast and brightness.
Description
The invention belongs to jumbotron and show the field.
The present invention relates to a kind of seam of eliminating spliced jumbotron display screen, improve the screen panel of visual contrast and image quality.
Super large screen displaying because display area generally more than several square meters, is difficult to make with individual monitor, all adopts the mode that is spliced into jumbotron by several small displays than small size to make usually.For example use the matrix form CRT(cathode-ray tube (CRT) of less display area), matrix form PDP(plasma discharge shows), the LCD(liquid crystal display), the VFD(vacuum fluorescence shows), EFD(electronics fluorescence shows) and the EL(electroluminescence show) etc. the jumbotron demonstration that is spliced into of display.There are the following problems usually for the at present this jumbotron display screen that is formed by the display splicing than small size:
1. shown image can be seen tangible splicing seams;
2. in order to reduce the influence of splicing seams to image quality, the spacing between each pixel in each small displays should be identical with splicing seams place pixel pitch, thereby reduced the efficient lighting area of display, reduced the mean flow rate of display screen;
3. owing between each pixel sizable non-luminous gap is arranged all, therefore seem that image point is sparse, image is discontinuous, influences image quality;
4. display panel is generally glass, and ring mirror light is had tangible direct reflection, and visual contrast is low.
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of and eliminate the indicator screen panel that splicing seams reduces the spacing between each pixel and improves the display contrast, thereby improve the displayed image quality.
Display pannel of the present invention comprises:
A transparency carrier;
The one side towards display of said transparency carrier is a cylindrical mirror identical with pixel graphics, and cylindrical mirror is corresponding with pixel edge;
The part that the outside surface of said transparent panel is corresponding with light-emitting pixels is a series of isoceles triangle prisms, the vertical direction configuration.With between the pixel not the luminous zone corresponding be the black light-absorbing wall, be used to intensify.
Describe display pannel of the present invention in detail below in conjunction with accompanying drawing.Wherein
Fig. 1 is the splicing synoptic diagram of spliced super large screen displaying; Fig. 2 is the structure of display pannel of the present invention and the synoptic diagram that combines with spliced display thereof.
Situation when Fig. 1 represents the adjacent small displays splicing of two of spliced display screens.101 and 102 are respectively two adjacent splicing small displays among the figure, and 103,104 are respectively display pannel and backboard, and 105 is the sealing side wall of small display, and 106 expressions comprise the pixel of red (R), blue (B), green (G) luminous point.Spacing between the adjacent image point between the two adjacent small displays is D
1, it comprises the clearance t between the display screen, display side wall thicknesses T, and the gap a between luminous point and the side wall.As seen from the figure, D
1-t+2T+2a.D among Fig. 1
2Be the spacing between each pixel in the small display, luminous uniformly in order to obtain, D
2Should equal D
1
Because manufacturing process, t and T can not subtract very for a short time, i.e. D
1Often quite big, thereby in displayed image, can see tangible splicing seams, influence image quality.
The invention provides a kind of display pannel that splicing seams can improve the displayed image contrast simultaneously again of eliminating.Its principle as shown in Figure 2,201 and 202 is two adjacent small displays among the figure, 203 is display pannel of the present invention, it is a transparent panel 204, its one side towards display screen is a cylindrical mirror 205 that a series of gardens cylinder or other curved surface are arranged, each cylindrical mirror is corresponding with each pixel edge 206 of display screen, with pixel luminous component 207 corresponding surfaces can be that the plane also can be a curved surface.The light that is sent by light-emitting pixels edge such as B point through cylindrical mirror 205 refractions, produces a virtual image that has amplified, shown in b among the figure.The b point obviously outwards moves, thereby seems to reduce or eliminated splicing seams.
The image point between each pixel in the small display in like manner also forms the virtual image that amplifies after suitable cylindrical mirror refraction, promptly seem in the small display also very close to each other or the gap is very little between each pixel.
If the gap length in seam between the display screen and the display between each image point does not wait, then the curvature of corresponding cylindrical mirror can be different, to obtain even image.
Two directions, level and vertical direction of display screen all have such cylindrical mirror, thereby make each pixel gap all become very little on level and vertical two directions, thereby have improved the quality of displayed image.
The appearance of panel 204 has two kinds of structures among Fig. 2.The one, a series of isoceles triangle prisms 208, two, black light-absorbing partition wall 209.Triangular prism 208 is positioned on the light-emitting pixels face, its effect has two: one, makes the light that is come by the top be folded to below or two sides through the prism surface reflection, reduce the part of reflection of ambient light, eliminate the direct reflection of display surface glass, intensify to the observer; The 2nd, the optically focused effect is arranged, strengthen the brightness of displayed image, also intensify simultaneously.
The black light-absorbing wall 209 of panel 204 is positioned on each pixel gap, and its effect is to absorb the surround lighting of incident and through the panel reflected ambient, it can be trapezoidal wall, can be stalk also, thereby improves visual contrast.
On the level of panel and vertical two directions black light-absorbing wall 209 is arranged all, thus absorbing environmental light more effectively.
Display pannel of the present invention has following advantage:
Display pannel of the present invention can be eliminated the splicing seams in the spliced jumbotron demonstration image, improves to show image quality;
Display pannel of the present invention can be eliminated the gap between each pixel of spliced jumbotron, improves to show image quality;
Display pannel of the present invention can strengthen luminosity, falls base ring border reflection of light, thereby improves the contrast that shows image.
Claims (5)
