Problems solved by technology

[0012] Also, as described above, since the LCOS panel assembly is manufactured by connecting a large number of parts, a large number of connection parts are generated, and even after the completion of the production of the projection system, since the residual stress remaining in the connection parts causes continuous deformation, there is a possibility that matching cannot be performed. The problem
If image matching is not performed in the LCOS panel assembly, it is difficult to reflect ideal pixels, resulting in image distortion

Embodiment Construction

[0032] Hereinafter, a projection system and an LCOS panel assembly thereof according to the present invention will be described in detail with reference to the accompanying drawings.

[0033] figure 1 is a perspective view of a projection system according to the invention, and figure 2 is an exploded perspective view of a display of a projection system according to the present invention.

[0034] refer to figure 1 and 2 , The projection system 1 according to the present invention includes: a screen 2 for displaying images, a front panel 3 arranged under the screen 2 , and a rear cover 4 arranged at the rear of the screen 2 .

[0035] Moreover, a space between the screen 2 and the rear cover 4 is provided for separating the light projection space and the light engine (see image 3 The reference number 10) the partition 6 of the accommodation space. A reflector 5 is provided inside the rear cover 4 to reflect light projected from the light engine 10 to the screen 2 and the...

Abstract

The invention provides a LCOS panel assembly of a projection system comprising: a LCOS panel; a panel support supporting the LCOS panel and coupled to the quad side; a quarter-wave plate provided at the front side of the LCOS panel to polarize light; a quarter-wave plate holder rotatably supported about the panel support at a state where the quarter-wave plate is coupled thereto; and adhesives interposed on a contact surface of the quarter-wave plate holder and the panel support, so that foreign substance is prevented from being injected on a optical path of the LCOS panel assembly of the projection system or image matching is prevented from being deteriorated.

Description

[0001] This application claims priority to Patent Application Nos. 10-2005-0071767, 10-2005-0071768, 10-2005-0071770 filed in Korea on Aug. 5, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to projection systems, and in particular, to LCOS panel assemblies for projection systems, by which projection systems can provide high-definition screens for extended periods of time in reflective projection systems by The LCOS panel forms an image. [0003] In particular, it relates to an LCOS panel assembly in a projection system, and an image matching method of the LCOS panel assembly, which can provide a high-definition screen despite continuous use of the projection system for a long period of time, since injection of foreign substances into the inside of the LCOS panel assembly, and after a large number of parts constituting the LCOS panel assembly are connected to each other, deformation caused by resid...
