LCD micromotion exposure and development device

Abstract

It is a LCD micro exposal image-developing device used in LCD digit image-developing system. It adopts a group of emitting diodes fixed on the LED base plate of red, green and blue color. One group of calibration lens in the rack forms the emitting unit, which together with the light mixture cylinder and rough glass form the emitting system. The emitting system, LCD vibration bench, focus-adjusting project head and printing paper total axis form the whole LCD micro exposal image-developing device. And the LCD micro bench comprises micro bench base plate, LCD chip, LCD rack, micro bench limit block, piezoelectricity ceramics, piezoelectricity limit block and spring pad.

Description

technical field [0001] The invention provides a micro-moving exposure and developing device for LCD (liquid crystal) image technology, which is used to improve the lower image quality caused by the low aperture ratio and low available resolution of the LCD. It belongs to the technical field of digital imaging. Background technique [0002] At present, most of the imaging systems that can output high-quality images come from companies such as Fuji, Kodak, and Noris. They use laser scanning exposure or low-light valve exposure methods, coupled with corresponding processing equipment, the price is expensive, and each unit is the lowest. It also needs to reach 700,000 yuan, which makes it difficult for most digital color expansion shops to accept. It can be seen that foreign technologies mainly have the following deficiencies: (1) The structure and technology of foreign imaging systems are complex and difficult to realize; (2) The cost is high and the utilization rate of equipm...

[0002] At present, most of the imaging systems that can output high-quality images come from companies such as Fuji, Kodak, and Noris. They use laser scanning exposure or low-light valve exposure methods, coupled with corresponding processing equipment, the price is expensive, and each unit is the lowest. It also needs to reach 700,000 yuan, which makes it difficult for most digital color expansion shops to accept

It can be seen that foreign technologies mainly have the following deficiencies: (1) The structure and technology of foreign imaging systems are complex and difficult to realize; (2) The cost is high and the utilization rate of equipment is low, making it difficult for consumers to accept; (3) Some key components used in the technology At present, it is still completely dependent on foreign supplies, and it is difficult to achieve industrialization, which seriously restricts the start and formation of my country's digital imaging industry

[0003] At present, there are very few digital imaging systems developed in China, and most of them use LCD technology. Due to the limitations of the low resolution and low aperture ratio of LCDs, it is far from meeting people's requirements for image quality when outputting larger-sized images, that is, The image resolution is extremely low; a small number of digital imaging systems use LCOS (liquid crystal on silicon) technology. Due to the low yield rate of LCOS and the technology is not stable enough, it cannot be used in practical applications at all.

[0004] At present, most LCD-based imaging systems use halogen lamps or xenon lamps as lighting sources, the output image color is less vivid, and it is difficult to control the color balance.

In addition, the available resolution of the current LCD is low, and the current domestic LCD-based imaging technology has no additional technical breakthroughs, resulting in only small-sized images being processed, and when the output image size is large, there will be a dark grid effect; based on The digital imaging system of LCOS cannot achieve practical application at all
