Abstract

The invention discloses a projector and a laser television, wherein the projector and the laser television belong to the field of displaying technology. The projector comprises a housing, a reflector and an adjusting assembly. The reflector has an axisymmetric structure with a symmetry axis. The adjusting assembly is fixedly connected with the housing and abuts against two edges of the reflector. The adjusting assembly is used for adjusting a pressure generated by a contact part between the adjusting assembly and the reflector. The two edges are on the reflector and furthermore are arranged at two sides of the symmetry axis. According to the projector and the laser television, the pressure generated by the contact part between the adjusting assembly and the reflector is adjusted through the adjusting assembly, thereby preventing a temperature drift phenomenon of the projector and simplifying the integral production process of the projector. The invention is used in a projector production process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a projector and a laser TV. Background technique [0002] The current laser TV can include a projector and a screen. The projector can include: an ultra-short-focus lens and a reflector. The light emitted by the ultra-short-focus lens in the projector is projected onto the screen after being reflected by the reflector, so that Form the image. The reflecting mirror is an axisymmetric structure, and there is a symmetry axis. [0003] When a focal point in the reflector is aimed at an object, not only the points on the plane where the focal point is located can see the object clearly, but also within a certain thickness above and below the plane, the thickness of this clear part is the depth of focus. Please refer to figure 1 , figure 1 It is a simulation diagram of focal depth of a reflector provided by the prior art. The reflector has 4 edges in total, and the focal depths o...
