Embodiment

[0038]Such asfigure 1 withfigure 2As shown, the present embodiment provides an adjustment structure 17 that does not loss pixel projection screen, including: a two-dimensional slide mechanism and a drive device.

[0039]The two-dimensional sliding mechanism is used to mount the projection lens 7, and the projection lens 7 is mounted on a two-dimensional sliding mechanism. The output of the drive device is connected to one side of the two-dimensional sliding mechanism, and the two-dimensional sliding mechanism is moved up and down by the drive.

[0040]Among them, the two-dimensional sliding mechanism is used to implement the sliding adjustment of the two directions on the same plane, and achieve the adjustment direction. The projection lens 7 can be mounted on a two-dimensional slide mechanism, so that the projection lens 7 can follow the two-dimensional sliding mechanism to achieve a change in the position of the projection lens 7. Among them, a through hole for light is provided on a tw...

Abstract

The invention relates to a transverse and vertical adjustment structure of projection screen without pixel loss and a projector, and belongs to the technical field of projection. The transverse and vertical adjustment structure of the projection screen comprises a two-dimensional sliding mechanism used for installing a projection lens installed at the center of the two-dimensional sliding mechanism, a driving device with the output end connected with one side of the two-dimensional sliding mechanism, and being capable of driving the two-dimensional sliding mechanism to move up, down, left and right in the vertical direction. The invention further provides a projector. The transverse and vertical adjustment structure of the projection screen can automatically adjust the horizontal and vertical of the screen without pixel loss of a projection picture.

Description

Technical field[0001]The present invention belongs to the field of projection techniques, and more particularly to adjustment structures and projectors that do not lose pixels.Background technique[0002]Now the projector products on the market, their projection screens are basically used by horizontal screen. If you need to play the picture, video and other materials such as the vertical screen, it is basically the pixel cutting of the projected picture, with the image Electronic zoom technology, the desired vertical screen content is completely displayed on the projection screen.[0003]The main problem with this is that the screen area displayed by the vertical screen is much smaller than the screen area displayed by the projector. It is also a lot of pixels, and the displayed vertical screen content is not only small, but also sharpness. not tall.[0004]Nowadays, the projector products have not been seen that their projection display screen automatically rotates from the horizontal s...
