Problems solved by technology

[0003] In the existing technology, projection display products are prone to "smear" phenomenon
The "smear" phenomenon is mainly caused by two reasons: the first reason is that the liquid crystal responds for a certain period of time, and there will be an intermediate state of liquid crystal molecules when switching from the previous image to the next image. It will cause blurring of the image; the second reason is that the human eye has a residual visual effect, and the image remains on the retina of the human eye for 10-12ms, so that the first and second images will overlap, resulting in image blur Vague
[0004] If a DMD chip with a faster response speed is used, the "smear" phenomenon caused by the pixel response time will be improved, but the "smear" phenomenon caused by the residual human vision still exists

Abstract

The invention relates to a fluorescent wheel and a projector. The fluorescent wheel comprises a base plate and further comprises a light conversion part, a light transmission part and a light absorption part. The light conversion part, the light transmission part and the light absorption part are arranged on one side of the base plate and arranged in the circumferential direction of the base plate. Light emitted by the light conversion part can be emitted from one side of the base plate.

Description

technical field [0001] The invention relates to a fluorescent wheel and a projector. Background technique [0002] Among various light sources, the fluorescent light source can obtain high-intensity light emission by increasing the energy density of the excitation light irradiating the fluorescent substance or by increasing the output of the excitation light. In projection display products, fluorescent lighting is also applied. [0003] In the prior art, projection display products are prone to "smear" phenomenon. The "smear" phenomenon is mainly caused by two reasons: the first reason is that the liquid crystal responds for a certain period of time, and there will be an intermediate state of liquid crystal molecules when switching from the previous image to the next image. It will cause blurring of the image; the second reason is that the human eye has a residual visual effect, and the image remains on the retina of the human eye for 10-12ms, so that the first and second ...
