The invention discloses a laser projection television for electrically adjusting the size of the projected picture, which includes: a projection host and a screen, and also includes a host tray, a screen hanger, a base, a host horizontal movement component, and a screen lifting movement component; the projection host is arranged on the host On the tray; the screen is set on the screen hanger; the base is set under the host tray and the screen hanger; the base is connected to the host tray through the host horizontal movement component, and the host horizontal movement component drives the host tray to move horizontally relative to the screen; The screen is connected to the screen hanger through the screen lifting movement component, and the screen lifting movement component drives the screen to move up and down on the screen hanger; the host horizontal movement component and the screen lifting movement component drive the host tray and the screen to move synchronously through a gear linkage structure . The invention can improve the adjustment efficiency and precision of the projected image size, has reliable performance and lower manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of laser televisions, in particular to a laser projection television for electrically adjusting the size of a projected picture. Background technique [0002] Users of laser projection TVs sometimes have the need to adjust the size of the projected screen. To adjust the size of the projected screen, it is necessary to adjust the depth position of the laser TV host in the horizontal direction and the height position of the screen in the vertical direction. However, currently on the market Laser projection TVs are mainly divided into two categories, one of which does not have the function of adjusting the size of the projected screen, and the other requires manual adjustment of the positions of the laser projection TV host and the screen to adjust the size of the projected screen. The former is missing this function and cannot meet the needs of users; the latter requires the user to get up from the viewing pla...
