Problems solved by technology

[0003] At present, there is also a means of using projection splicing technology to expand the picture and improve the resolution. Chinese patent CN20111009L448 and patent application CN201L10085674 both record the use of projection splicing of multiple pictures to obtain high resolution, high physical size or picture display output on a curved screen. However, the existing projection splicing technology still uses multiple projectors, which requires a lot of equipment and is relatively expensive.

Embodiment 1

[0040] Such as figure 1 and 2 As shown, the projection lenses L1 and L2 are respectively aimed at the projected image areas Z1 and Z2 on the projection screen; the original image information is input into the image processing unit, and the image processing unit is a software system whose function is to segment the original image to produce Partition image, the partition image information is processed by the display chip to form incident light in different time periods; in this embodiment, the incident light 3 is the light loaded with the partition image after being processed by LCD, LCoS or DMD, etc., in the image processing unit ( figure 1 not shown in ), control the incident light 3 in different time periods to be the partition image corresponding to the time period, and deflect the scanning galvanometer 1 to the corresponding position; in the time period I, the incident light 3 is the partition image D1, and the reflection The light 3-1 is projected to the projected image ...

Embodiment 2

[0044] Such as Figure 4 and 5 As shown, the scanning mirror 1 is replaced by a mirror 2 with four reflecting surfaces; the projection lenses L1, L2, L3 and L4 are respectively aligned with the projected image areas Z1, Z2, Z3 and Z4 on the projection screen; the original image information input Segmentation in the image processing unit to generate partitioned images, the partitioned image information is processed by the display chip to form incident light in different time periods; in this embodiment, the incident light 3 is processed by LCD, LCoS or DMD and loaded with partitioned images light, in the image processing unit ( Figure 4not shown in ) control, the incident light 3 is controlled by different time periods to be the partition image corresponding to the time period, and the mirror 2 with four reflecting surfaces is rotated to the corresponding position; in the time period I, the incident light 3 is In the partition image D1, the reflected light 3-1 is projected t...

Abstract

The invention discloses a multi-image projection display device and a multi-image projection method. The multi-image projection display device comprises a projector, a projection screen, a projection reflecting mirror, more than two projection lens, an image processing unit and a motor; the projector comprises a display chip; the projection reflecting mirror is a vibration mirror or a multi-side reflecting mirror; emergent light processed by the display chip firstly enters the projection reflecting mirror and then enters the projection lens; a projection time-sharing control system continuously set a plurality of time sections; different partition images are loaded through the incident light at the different time sections; the projection reflecting mirror enable the different partition image to the corresponding projection lens and then enter the projection image areas and finally an integral image is formed; scanning is recycled sequentially at all time sections. According to the technical scheme of the multi-image projection display device, multi-image splicing is achieved through a single projector and a good resolution ratio or a larger display image can be obtained under the premise that the equipment costs are controlled.

Description

technical field [0001] The present invention relates to the technical field of projection display, in particular to a multi-screen projection display device that can provide projection display with high resolution or large projection area, and also relates to a multi-screen projection method using the projection device. Background technique [0002] Projectors are an indispensable display tool for theaters and presentations. Among them, the resolution of the projection area is a key parameter that needs to be continuously improved in the display area; at the same time, a larger projection area is also the goal that projection display has been pursuing. If the current projection display wants to increase the resolution, it is necessary to increase the resolution of LCD (Liquid Crystal Display, liquid crystal panel), LCoS (Liquid Crystalon Silicon, liquid crystal on silicon) or DLP (Digital Light Processing, digital light processing), which requires great technological progres...
