Projection display device adopting self-luminous pixel array device

Abstract

The invention discloses a projection display device adopting a self-luminous pixel array device. The projection display device comprises the self-luminous pixel array device and a projection lens, theself-luminous pixel array device can actively emit light, and each image display pixel contained in the self-luminous pixel array device is an independent point light source, so that the independentaddressing and independent driving lighting of each pixel are achieved. The projection lens amplifies and displays a picture generated by the self-luminous pixel array device to realize the display ofthe projection picture. According to the projection display device provided by the invention, the self-luminous pixel array device is adopted as a light modulator, the current situation that an existing projection display system needs an independent light source, an independent lighting system and an independent imaging light modulation component, is broken through, the system stray light and aberration are reduced through a simple system structure, and the high-image-quality and ultrahigh-resolution display is realized.

Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a projection display device using a self-luminous pixel array device. Background technique [0002] Projection display products currently on the market, such as laser TVs, all use independent light sources, such as mercury lamps, LEDs, or LDs, etc., modulate the light emitted by the light source through a complex lighting optical system, and irradiate the independent imaging light modulation device, such as DMD, LCD, LCOS, etc., and finally realize the projection screen display through the lens. [0003] In the existing projection display solutions, core components such as light sources and imaging light modulation devices have been monopolized by many giant companies, resulting in the development of projection display systems being restricted by others. Moreover, in the process of system scheme design, restricted by the performance parameters of core components, the ...

Problems solved by technology

[0003] In the existing projection display solutions, core components such as light sources and imaging light modulation devices have been monopolized by many giant companies, resulting in the development of projection display systems being restricted by others.

Moreover, during the system design process, restricted by the performance parameters of core components, the homogeneity of products on the market is serious, and key performance indicators cannot be independently defined

At the same time, the light emitted by the light source needs to pass through a complex illumination optical system before it can be irradiated on the imaging light modulator. In this process, stray light and various system aberrations and chromatic aberrations will inevitably be generated, resulting in low contrast and poor color in the projection display screen. Defects that affect subjective effects such as not being gorgeous

In addition, display technology is advancing rapidly towards ultra-high-definition, but it is difficult to develop projection-type imaging light modulation devices in the direction of higher resolution, and technology updates are slow, which makes projection display technology unable to keep up with the pace of development of other display technologies
