3D high definition projector

Abstract

The invention discloses a 3D high definition projector, wherein a housing is installed on an upper surface of a base through a screw; a cover body is movably installed on an upper edge of the housingthrough a rotating shaft; a signal processor and a storage battery are arranged in the housing; a projection port is formed in a front outer wall of the housing, and a power interface, a USB interface, an SD card socket and a high definition data interface are formed in a side face of the projection port; heat dissipation holes are uniformly formed in an inner wall of the housing; an outer wall board at the rear of the housing is a serrated heat dissipation plate; a switch button is arranged at the center of the upper surface of the cover body; an adjusting roller is further embedded in the outer wall of the housing; and a gear rack is arranged on the outer wall of the adjusting roller and is engaged with an upper segment side face of an adjusting screw. The 3D high definition projector disclosed by the invention is reasonable in structure, good in heat dissipation performance, clear in projection picture and is power failure resistant.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a 3D high-definition projector. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. The projectors used need to adjust the elevation angle during use, so that the projected image is stable and the writing is clear, which is easy for the audience to view. The elevation angle adjustment of the projector is manually adjusted. This often results in unclear or even ghosting of the image, which needs to be adjusted again, which is time-consuming and laborious, and the effect is not satisfactory. At the same time, the fixed brightness needs to be adjusted manually, which cannot ...

Projectors are widely used in homes, offices, schools, and entertainment venues. The projectors used need to adjust the elevation angle during use, so that the projected image is stable and the writing is clear, which is easy for the audience to view. The elevation angle adjustment of the projector is manually adjusted. This often results in unclear or even ghosting of the image, which needs to be adjusted again, which is time-consuming and laborious, and the effect is not satisfactory. At the same time, the brightness needs to be adjusted manually, which cannot fit the human visual system well.
