Abstract

The invention discloses projection equipment and a display method of a projection image, and belongs to the field of projection display. A mark is arranged on a color wheel in the projection equipment, and a mark detector in the projection equipment can send a detection signal to a control circuit when detecting the mark on the color wheel in a rotating state. When the control circuit receives the detection signal, if it is determined that the color of the light beam corresponding to the current light valve control signal of the light valve is different from the color of the light beam corresponding to the marked position, the current light valve control signal of the light valve is adjusted. Therefore, it is ensured that the color of the displayed projection image is not disordered, and the display effect of the projection image is ensured.

Description

technical field [0001] The present disclosure relates to the field of projection display, in particular to a projection device and a method for displaying projection images. Background technique [0002] Currently, projection equipment includes control circuits, blue lasers, color wheels, light valves, and projection lenses. During the process of projecting and displaying projected images, the control circuit can control the blue laser to emit blue laser. After the blue laser is irradiated to different areas in the color wheel, the color wheel can emit light beams of different colors. At the same time, the control circuit can control the flipping of the light valve according to the red color value, green color value and blue color value of the pixel in the projected image. In the process of the control circuit controlling the light valve to flip according to a certain color value, it is necessary to ensure that the color wheel can emit the light beam of the same color onto...
