Problems solved by technology

Since each display unit is physically independent and has its own independent package, when two or more display units are spliced ​​into a large-screen display, a relatively large gap is formed at the joint of the screen, which affects the visual effect of the screen
At the same time, the shape and size of the above-mentioned display devices are too rigid, which cannot meet the increasingly personalized user needs.

Embodiment 1

[0040] Such as figure 1 , 5 , 6, 7, 8 and 9, the expandable display device includes a projection device 1, and the projection device 1 includes a projector case 101, in which a projection reflector 102, a projection lamp 103, a condenser 104, Heat insulating glass 105, Fresnel mirror 106 and LCD lens 107. The projection lamp 103 is a metal halide bulb, a UHE bulb, a UHP bulb, a xenon bulb or an LED bulb. The projection device 1 generates a projected image, and the projection device 1 is connected and controlled by a projection device control board 10 . The projection device control board 10 is mainly used to intercept the corresponding digital video image information, and correct the video image, transmit the corrected video image information to the connected projection device 1, and drive the projector to correctly display the image information .

[0041]The projector housing 101 of the projection device 1 is connected with a light guide main pipe 2 , which can be compose...

Embodiment 2

[0057] Such as figure 2 and 3 As shown, the projection device 1 in the expandable display device is arranged under the projection screen 7 , that is, in the base 8 . The projector housing 101 of the projection device 1 is connected with the main light guide pipe 2, and the main light guide pipe 2 is connected with the light guide branch pipe 4. The main light guide pipe 2 and each light guide branch pipe 4 form an L-shaped structure, and a piece of The image produced by the projection device 1 is projected to the reflector 3 of the projection screen 7, and other structures are the same as those in Embodiment 1, and it can finally achieve the same technical effect as Embodiment 1.

Embodiment 3

[0059] In the expandable display device, the projection screen 7 can be designed as a three-dimensional projection screen, which can be a cuboid, a cube, a polyhedron, a curved body, a hollow sphere (such as Figure 4 ), hollow cylinder (such as Figure 5 ), hollow drum or hemispherical structure. A set of projection lens 5 is arranged inside the projection screen 7, and the projection lens 5 is connected to the projection device 1 arranged around the projection screen 7 or in the base 8 through the conduit main pipe 2, the conduit branch pipe 201 and the conduit branch pipe 4. Other structures and embodiments 1, it can finally achieve the same technical effect as that of embodiment 1.

Abstract

The invention relates to an expandable display device and a method for processing a video by utilizing the same, which belongs to the technical field of display devices. The expandable display device provided by the invention comprises a projection screen, wherein one or more group of projection devices are arranged at the rear of, at the periphery of, at the lower part of or in the projection screen; the projection devices are connected with and controlled by a projection device control electroplate; the projection ends of the projection devices are connected with a light guide header pipe; the light guide header pipe comprises one or more than one light guide branched pipe; the light guide branched pipes are connected with light guide branch pipes; reflectors which project the images generated by the projection devices to the projection screen are arranged in the light guide branch pipes; projection lenses are arranged at the ports of the light guide branch pipes; and the projectionscreen is arranged in front of the projection lenses. Compared with the prior art, the equipment and method provided by the invention have the advantages that the brightness of display frames can be enhanced by more than 30%; the thickness of the screen is shortened by more than 80%; the weight is lightened by more than 40%; the heat productivity is reduced by more than 33%; the electric energy consumption is reduced by more than 35%; and the color uniformity of the images is enhanced by more than 31%.

Description

technical field [0001] The invention belongs to the technical field of display devices, and in particular relates to an expandable display device and a video processing method using the device. Background technique [0002] At present, most of the display systems at home and abroad use LCD, PDP, and DLP display units for display, and large screens are formed by independent physical splicing of the above display units. Since each display unit is physically independent and has its own independent package, when two or more display units are spliced ​​into a large-screen display, a relatively large gap is formed at the joint of the screen, which affects the visual effect of the screen. At the same time, the shape and size of the above-mentioned display devices are too rigid, which cannot meet the increasingly personalized needs of users. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to design and p...
