Embodiment 1

[0053] This embodiment provides a front projection all-in-one machine, comprising: a casing; a reflective screen arranged outside the casing and fixed on the casing; The optical engine receives the image signal, converts the received video signal into an image, and projects it on the reflective screen.

[0054] Traditional projectors generally adopt the method of hoisting. If there is a ceiling light, the projector cannot be hoisted, otherwise the chandelier will block the light of the projector, making the display screen unable to display normal images. For places that have been decorated, hoisting the projector The projector will not only damage the decoration materials, but also destroy the overall decoration style, causing problems such as affecting lighting, which will limit the installation position of the projector.

[0055] Moreover, the relative positions of the traditional projector and the display screen are not fixed. If the two are not adjusted during installation...

Embodiment 2

[0076] This embodiment provides a reflective screen, including: a substrate and a diffuse reflective layer covering one side of the substrate.

[0077] The diffuse reflective layer can diffusely reflect light, so that the reflective screen provided by this embodiment has a wider viewing angle than the prior art.

[0078] Preferably, between the substrate and the diffuse reflection layer: a reflection layer covering the surface of the substrate and a diffusion layer covering the surface of the reflection layer facing away from the substrate; layer covering the surface of the diffusion layer facing away from the substrate.

[0079] Specifically, its structure is as Figure 4 As shown, it includes: a substrate 400; a reflective layer 401 covering one side of the substrate 400; a diffusion layer 402 covering the surface of the reflective layer 401 facing away from the substrate 400; The diffuse reflective layer 403 on one side of the substrate 400.

[0080] The display screen u...

Abstract

The invention provides a positive projection integrated machine and a reflective screen. The positive projection integrated machine comprises a casing, a reflective screen which is arranged outside the casing and is fixed on the casing, and an optical engine which is fixed on the casing. The positive projection integrated machine has the advantages of compact structure and simple assembly, and the installation and debugging are not needed in use. The reflective screen comprises a substrate and a diffuse reflection layer which covers a surface at one side of the substrate, the reflective screen can carry out diffuse reflection on light, and thus the angle of view is increased.

Description

technical field [0001] The invention relates to the technical field of large-screen display, and more specifically, relates to an all-in-one front projection machine and a reflective screen. Background technique [0002] With the continuous development of modern society, people have more and more demands on display technology. Among them, large-screen display technology is widely used in monitoring centers, network management centers, temporary meetings, technical lectures and other aspects. [0003] Liquid crystal or plasma displays, or projection displays are commonly used in large-screen display technologies. Large-size LCD or plasma displays need to be customized, and the cost is high, the energy consumption is high, and the later maintenance cost is high. Compared with liquid crystal or plasma displays, projection display is easy to realize large-scale display, and its cost and energy consumption are lower. Projection display uses a projector to project images or vide...
