Abstract
The utility model belongs to the field of daily life article, specifically to a rear projection display unit with multiple built-in projecting apparatuses. The utility model is characterized in that a plurality of rear projection units compose an integral screen display device, and each rear projection unit is equipped inside with four or two projecting apparatuses (they can be LCDs, DLPs and LCOSs, etc.) which can display a color image independently, and each projecting apparatus displays a part of image which can be displayed by the unit under the control of its internal control system software, and these projecting apparatuses jointly complete the display of an image.
Description
Affiliated technical field:
The utility model belongs to the daily living article field, is a kind of back projection display unit of built-in a plurality of projection arrangements specifically.
Background technology:
The jumbotron that uses shows (more than during display screen size 100) at present, is generally LED shows or the back projection mode combines " projection wall ".Dual mode respectively has pluses and minuses: LED mode brightness height, but picture coarse (the unit are pixel is less than the back projection mode far away), and stereovision is poor: and back projection compound mode image is meticulous, levels are rich, but brightness is difficult to satisfy the outdoor application requirement not as good as the LED mode.Dual mode is owing to structure and technology, and price is all extremely expensive, so be necessary to research and develop a kind of device that collects above-mentioned advantage.
Summary of the invention:
The objective of the invention is to: solve the weak point of existing product, the brightness that has improved composite type rear-projection ultra-large screen display system greatly makes this system have the image of ultrahigh resolution, super brightness.
The technical scheme that its technical problem that solves the utility model adopts is: be the image that makes ultra-large screen display system have high definition, and the brightness of superelevation (brightness can surpass the similar display system of all uses at present), and also cost is lower.The technical characterictic that the utility model adopted is: by a plurality of back projection units screen display device that forms a whole, but the projection arrangement that four or two same independent displaying coloured images are installed in each back projection unit the inside (can be LCD, DLP, LCOS etc.), under the control of portion's control system software within it of each projection arrangement, each shows that this unit answers the part of display image, finishes the demonstration of piece image jointly, and obviously brightness has improved greatly.The utility model projection arrangement installing rack is installed in the projecting cell housing and is attached thereto and connects, in the unit in projection arrangement, the unit in No. two projection arrangements, the unit in No. three projection arrangements, the unit No. four projection arrangements be installed in respectively on the projection arrangement installing rack, projection screen and projecting cell housing in abutting connection with and corresponding with each projection arrangement in the projecting cell housing.
Utility model is based on above-mentioned purpose and a kind of high definition that designs, the display unit of high brightness, and it is one of them unit of back projection compound mode ultra-large screen display system.It is complicated, in fact simpler: as 1, can to use the better simply projection arrangement of structure that this method seems; 2, can use the image of the projection arrangement display of high resolution of low resolution, have only the projection arrangement of 640 * 480 resolution such as each, can finish jointly for four and show 1024 * 768 or 1280 * 960 images.
The beneficial effects of the utility model are: solve the weak point of existing product, the brightness that has improved composite type rear-projection ultra-large screen display system greatly makes this system have the image of ultrahigh resolution, super brightness.
Description of drawings:
Fig. 1 is the structural representation sketch of one 4 * 3 investigation of projection display system of the utility model composition.
Fig. 2 is equipped with the normal cross-section simplified schematic diagram of four projection arrangement unit for one of the utility model.
Fig. 3 overlooks the section simplified schematic diagram for the utility model.
Fig. 4 is the utility model left side section simplified schematic diagram.
As shown in the figure: in the 1 expression unit in projection arrangement, the 2 expression unit in No. two projection arrangements, the 3 expression unit in No. three projection arrangements, the 4 expression unit No. four projection arrangements, 5 represent that projection arrangement installing racks, 6 represent that projection screens, 7 represent the projecting cell housings.
Specific embodiment:
As shown in the figure: in the 1 expression unit in projection arrangement, the 2 expression unit in No. two projection arrangements, the 3 expression unit in No. three projection arrangements, the 4 expression unit No. four projection arrangements, 5 represent that projection arrangement installing racks, 6 represent that projection screens, 7 represent the projecting cell housings.
Be the image that makes ultra-large screen display system have high definition, the brightness of superelevation (brightness can surpass the similar display system of all uses at present), and also cost is lower.The technical characterictic that the utility model adopted is: by a plurality of back projection units screen display device that forms a whole, but the projection arrangement that four or two same independent displaying coloured images are installed in each back projection unit the inside (can be LCD, DLP, LCOS etc.), under the control of portion's control system software within it of each projection arrangement, each shows that this unit answers the part of display image, finishes the demonstration of piece image jointly, and obviously brightness has improved greatly.The utility model projection arrangement installing rack 5 is installed in the projecting cell housing 7 and is attached thereto and connects, in the unit in projection arrangement 1, the unit in No. two projection arrangements 2, the unit in No. three projection arrangements 3, the unit No. four projection arrangements 4 be installed in respectively on the projection arrangement installing rack 7, projection screen 6 and projecting cell housing 7 in abutting connection with and corresponding with each projection arrangement in the projecting cell housing.
Utility model is based on above-mentioned purpose and a kind of high definition that designs, the display unit of high brightness, and it is one of them unit of back projection compound mode ultra-large screen display system.It is complicated, in fact simpler: as 1, can to use the better simply projection arrangement of structure that this method seems; 2, can use the image of the projection arrangement display of high resolution of low resolution, have only the projection arrangement of 640 * 480 resolution such as each, can finish jointly for four and show 1024 * 768 or 1280 * 960 images.
The utility model has solved the weak point of existing product, has improved the brightness of composite type rear-projection ultra-large screen display system greatly, the image that makes this system have ultrahigh resolution, super brightness, and also cost is lower.
