Problems solved by technology

Due to the existence of stitching seams, when displaying a large-scale entire picture, the visual effect is flawed, and there is currently no good remedy in technology
Another solution to meet the demand for super-large-size display is to use a projector plus a projection screen. For example, the Chinese patent No. 200420041588 discloses a seamless splicing large-screen display device, which forms a seamless display through the seamless fusion of computer graphics. The fusion display system can solve the image visual defects caused by

Abstract

The invention relates to a display device which comprises a signal input source, an image processing device and an image output device, wherein the image processing device is connected with the signal input source, and the image output device is connected with the image processing device; the image processing device comprises an image segmentation processing device and an image joining processing device; the image segmentation processing device is connected with the signal input source, and the image joining processing device is connected with the image output device; the display device is characterized in that the image output device comprises an optical projection screen and at least two sets of projection devices arranged behind the optical projection screen; each projection device comprises a projector and two reflective mirrors; and the projection direction of the projector is slantwise intersected with the optical projection screen. The display device has the advantages of no-physical seam joining of images, uniform and perfect display, good display effect, small integral volume, thin thickness, good aesthetic property of appearance, small occupied space, good overall heat dissipation effect, low operating temperature and long service life.

Description

technical field [0001] The invention relates to a display device, in particular to a thin optical seamless splicing imaging display device. Background technique [0002] With the development of society and economy, there is an increasing demand for super-sized display walls, especially those with a display area larger than 3X1.5 meters. Currently, the display size of commonly used LCD or plasma TVs is up to 108". In super-large-size applications, Most people use LCD or optical projection splicing display walls. The splicing display wall is composed of several LCD TV units or optical projection display units. It can display super-large size, but there are physical splicing seams. The splicing seam is 5.3~7.3mm; the splicing seam of the optical projection unit is 0.5~1.0mm. Due to the existence of the splicing seam, the visual effect is not good when displaying a large-scale entire picture, and there is no better technology currently Another solution to meet the needs of supe...
