Abstract

The invention discloses a high-brightness uniform-chroma projection system. The projection system comprises an image quality feedback module which is connected with a control system for sending adjustment coefficients to the control system; the control system which is connected with a light source driving system and an optical processing system, performs algorithm analysis according to parametersin the adjustment coefficients, converts the parameters into commands for sending to the light source driving system, and at the same time, sends chip control instructions to the optical processing system; the light source driving system which is connected with the optical processing system and adjusts brightness of a specific point light source; and the optical processing system which receives and processes optical signals emitted by a light source in the optical processing system and then projects the optical signals through a lens. According to the invention, the brightness and the chroma uniformity of the projector are improved by use of an area optical accurate adjustment mode, at the same time, the dynamic contrast of images can also be improved, and the detail display of the imagesis better and more real.

Description

technical field [0001] The invention relates to the field of laser projectors, in particular to a projection system with high brightness and uniform chromaticity. Background technique [0002] The development and application of projectors has a history of many years, but the problems of brightness and chromaticity uniformity of projectors have always existed. With the development of technology, various methods for improving uniformity have been proposed in the fields of optics and electronics, and have been applied to projectors. However, the method of improving the uniformity of the optics is not perfect, and this optical method will reduce the light efficiency of the projector; the optical inhomogeneity of the projector is compensated by adjusting the brightness and chromaticity distribution of the signal picture , in order to achieve the purpose of improving the overall uniformity, this method can achieve a high uniformity of the picture, but the dynamic range of the pic...
