Abstract

The invention discloses a screen levelness adjusting mechanism and a projection display device, relates to the technical field of display, and aims to solve the problems of complex structure, large occupied space and disadvantage in the thinning design of a screen of a conventional screen levelness adjusting mechanism. The screen levelness adjusting mechanism comprises a reference part, a support shaft, a cam, a positioning hole, a locking pin and a support plate, wherein the reference part and the support shaft are arranged on the back surface of a screen; the cam is arranged on the support shaft in a sleeving way; a plurality of locking holes are formed in the cam, and are formed at intervals in a circular arc taking the shaft center of the support shaft as the circle center; the positioning hole is formed in the back surface of the screen, and can correspond to any one locking hole; the locking pin is inserted into one locking hole and the positioning hole to lock the cam; the support plate is arranged on a screen support body; the upper surface of the support plate is in contact with the contour surface of the cam to support the cam. The screen levelness adjusting mechanism is used for regulating the levelness of the screen when the screen is suspended on the screen support body.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a screen level adjustment mechanism and a projection display device. Background technique [0002] Ultra-short focus laser TV has been developed rapidly due to its advantages of wide color gamut, high brightness, long service life, energy saving and environmental protection. The ultra-short-focus laser TV includes a screen (hard screen) and a laser. When in use, the screen is usually hung on the wall. The laser light emitted by the laser is reflected by the screen and then enters the viewer's eyes along the set optical path to generate an image. [0003] In order to achieve a better display effect, there are higher requirements for the flatness and levelness of the screen. In the prior art, the screen is usually supported by a high-strength backplane so that the screen has a higher flatness; The screen level adjustment mechanism of the five-axis adjustment knob automatically ad...
