Description

Technical Field

[0001] This utility model belongs to the field of micro projection display assembly technology, specifically relating to a 3LCOS laser light source module color plate coupling assembly device. Background Technology

[0002] 3LCOS projection technology is an advanced projection display technology. It is based on LCOS (Liquid Crystal on Silicon) technology, and its main advantages are:

[0003] 1. Superior color performance: 3LCOS technology can independently modulate and control the three colors of red, green and blue, achieving more accurate color reproduction and making the image colors more realistic.

[0004] 2. High resolution: The LCOS panel itself has a high pixel density, and 3LCOS technology can achieve ultra-high-definition resolution of 4K or even 8K, providing extremely high image clarity.

[0005] 3. High contrast: Through precise control and modulation of light, 3LCOS technology can produce deeper blacks and brighter whites, thereby achieving high contrast image effects and making the picture more vivid and realistic.

[0006] These performance requirements place high demands on the installation precision of optical components in the light source module, especially the color plate. The flatness and angular errors of the color plate affect the light reflection path, reducing light utilization and image uniformity. Therefore, the calibration accuracy of the color plate typically needs to be controlled at the milliradian level. To meet this requirement, a high-precision color plate coupling and assembly device for 3LCOS laser light source modules is essential. Utility Model Content
