Embodiment

[0045] Such as figure 1 and figure 2 As shown, this embodiment provides a single-chip LCD projection structure, including: a solid-state light source 1 for generating the three primary colors of RGB, red, green and blue, a black and white LCD liquid crystal screen 3, a light-receiving lens 4, and a projection lens 5;

[0046] The three primary colors produced by the solid-state light source 1 are irradiated on the black and white LCD liquid crystal screen 3 separately, and pass through the black and white LCD liquid crystal screen 3 to irradiate on the light-receiving lens 4, converge and irradiate on the projection lens 5 through the light-receiving lens 4, and pass through the projection lens 5 Form a projection screen.

[0047] Among them, the solid-state light source 1 can stably produce the three primary colors of red, green and blue, with uniform brightness and pure color, without the problem of chromatic aberration. The solid-state light source 1 can be an LED light ...

Abstract

The invention relates to a monolithic LCD projection structure, a projector and a projection method, and belongs to the technical field of projection display. The monolithic LCD projection structure comprises a solid-state light source, a black-and-white LCD screen, a light receiving lens and a projection lens, wherein the solid-state light source is used for generating RGB red, green and blue three primary colors, the three primary colors generated by the solid-state light source are respectively and independently irradiated on the black-and-white LCD screen, penetrate through the black-and-white LCD screen, are irradiated on the light receiving lens, are converged by the light receiving lens, are irradiated on the projection lens, and form a projection picture through the projection lens. The invention further provides a monolithic LCD projector and a monolithic LCD projection method. According to the monolithic LCD projection structure, the brightness of a monolithic LCD projection product can be greatly improved, and the problem that an existing monolithic LCD projection product is insufficient in brightness is solved.

Description

technical field [0001] The invention belongs to the technical field of projection display, and in particular relates to a single-chip LCD projection structure, a projector and a projection method. Background technique [0002] A single-chip LCD projector refers to a projection device with only one LCD screen. [0003] The working principle of the existing single-chip LCD projection equipment currently on the market is: use a small-angle white light beam as an illumination source, irradiate it on a full-color, transmissive LCD screen, and use the projection lens to transform the LCD screen The image is enlarged and projected on the screen. The color image display of the current single-chip LCD projection equipment is completely realized by the full-color LCD liquid crystal screen. In order to realize color display, a full-color LCD screen needs to be added with a color film. Each small red, green, and blue color block on the color film corresponds to a small LCD pixel, and ...
