Realization method of synchronous lifting or synchronous translation of projection screen following rollable screen

Abstract

The invention discloses a method for realizing synchronous up-and-down or synchronous translation of a projection screen following a rollable screen. After the system is powered on and started, the projection screen first reports the current position of the screen to the projection host through a communication link, and the projection host reports the current position of the screen to the projection host according to the information obtained from the projection screen. The current screen position n0 of the projection image is preprocessed. After the projection host completes the preprocessing of the projection image, the image is projected onto the projection screen. The projection host informs the projection screen through the communication link to confirm that the current projection image has been processed according to The current position of the projection screen is aligned, and after the projection screen receives the confirmation information from the projection host, it drives the projection screen to the next position, and the projection host obtains the specific position of the next projection screen through the communication link. " and "projection screen" are designed as a real linkage system to achieve the perfect match between the projection screen and the projection screen to achieve the best display effect.

Description

technical field [0001] The present invention relates to the technical field of synchronous lifting or synchronous translation of a projection picture following a rollable screen, in particular to a method for realizing synchronous lifting or synchronous translation of a projection picture following a rollable screen. Background technique [0002] Under normal circumstances, there is no connection between the traditional projector and the emerging projection TV (hereinafter referred to as: projection host) and the screen displaying projected images (hereinafter referred to as: projection screen). projection display system. That is, the projection screen is not controlled by the projection host when it is curled or unfolded; when the projection host is turned off or turned on, the projection screen will not perform the curling or unfolding action accordingly. In some specific cases, projection system suppliers or projection system users will develop some simple "projection ho...

AI Technical Summary

Problems solved by technology

However, in the current existing design schemes, when the screen is rolled up or unfolded, the projected image cannot strictly follow the screen to move synchronously, the user experience is not good, and it also greatly limits the usage scenarios of this type of projection system. Therefore, , an improved technology is urgently needed to solve this problem existing in the prior art
