Embodiment

[0028] The embodiment provides a filter color wheel control system, such as figure 2 As shown, it includes a color filter wheel, a detection module 200, a processing unit 300, a motor and necessary supporting structures.

[0029] In the filter color wheel, such as figure 1 As shown, the filter area 110 is on the outer ring, and the marking area 120 is on the inner ring; the filter area 110 is divided into four color segments, such as red, green, blue, and yellow; the arcs corresponding to each color segment are not exactly the same , such as red 60 degrees, green 105 degrees, blue 90 degrees, yellow 105 degrees; the guide area 121 is a mirror surface, which can reflect near-infrared signals, and the front of the coding area 122 is equipped with a black light-absorbing material, which can absorb near-infrared signals. The radians of the coded areas corresponding to the four color segments are significantly different, such as 30 degrees for the red segment coded area, 45 degre...

Abstract

The invention relates to the technical field of filtering display and discloses a filtering color wheel, a filtering color wheel control system and a synchronous control method of a filtering color wheel, which solves the problems that the traditional method cannot directly distinguish each color filter, and the color saturation is poor. The filtering color wheel control system includes a filtering color wheel, a processing unit and a detection unit. The filtering color wheel comprises a base structure and a plurality of fan structures. All the fan structures form a complete circle. The fan structure includes a filtering region and a mark region. The filtering regions of the different fan structures are configured to transmit monochromatic light of different colors. Each mark region includes a coding region and a guide region, the coding region and the guide region are axially distributed, and each coding region corresponds to a different angle, the coding region is provided with coding information for identifying the color section of a fan-shaped region, and the guide region is provided with guiding information for guiding the excitation signal into the coding region. The invention is suitable for projection display devices.

Description

technical field [0001] The invention relates to a filter display technology, in particular to a filter color wheel, a filter color wheel control system and a synchronous control method for the filter color wheel. Background technique [0002] Filter wheels have been widely used in optical systems for generating color sequences, especially in projection display devices. [0003] Generally, the filter color wheel has two or more kinds of filter color chips, which are used in conjunction with the light source, and the light emitted by the light source passes through the filter color wheel to produce a certain color sequence. [0004] In projection display equipment, the color sequence needs to match the video display image to ensure the normal display of the image screen, that is, the filter color wheel needs to be synchronized with the light source and video image signal. Generally, the synchronization method of the filter color wheel is to paste a section of black tape on th...
