Laser projection system and starting method thereof

Abstract

The invention discloses a laser projection system and a starting method thereof, and belongs to the technical field of projection display. The method comprises the steps: after a laser projection mainboard and a motion compensation module are powered on, a first VBO system begins to perform handshake, after handshake succeeds, the laser projection mainboard controls an image correction module to be powered on, then a second VBO system begins to perform handshake, and after handshake succeeds, the laser projection mainboard controls an image display module to be powered on. And then, the third VBO system begins to perform handshake, and after the handshake succeeds, the image display module can receive a VBO image signal which is sent by the laser projection mainboard and sequentially passes through the motion compensation module and the image correction module, and the image display module can project an image based on the VBO image signal. Accurate sequential control over the laser projection main board, the motion compensation module, the image correction module and the image display module is achieved.

Description

technical field [0001] The present application relates to the technical field of projection display, in particular to a laser projection system and its starting method. Background technique [0002] Image transmission digital interface standard (English: V-BY-ONE, referred to as: VBO) technology has been widely used in 4K ultra-high-definition laser projection system products. [0003] At present, most laser projection systems include a VBO system for transmitting VBO signals. For example, the VBO system includes a laser projection main board and an image display module, wherein the laser projection main board is a sending end, and the image display module is a receiving end. The timing control process of the VBO system is as follows: After the transmitting end and the receiving end are powered on, the receiving end configures the hot plug detection (HTPDn) control pin and the clock lock (LOCKn) control pin in the receiving end to be high level; when the receiving end start...

AI Technical Summary

Problems solved by technology

However, for a complex laser projection system including a laser projection main board, a motion compensation module, an image correction module and an image display module, only the timing control of the VBO system including the laser projection main board and the image display module can be performed, and the laser projection cannot be controlled. The projection main board, motion compensation module, image correction module, and image display module perform accurate timing control, which may cause abnormal problems such as blue screen or blurred screen in the image projected by the laser projection system
