Problems solved by technology

[0003] However, the current method of manufacturing laser projection screens is cumbersome, complicated to process molds, expensive and time-consuming.
In addition, when background light such as indoor lighting and outdoor light sources is projected onto the laser projection screen, since the laser light source is the light of passive reflective projection equipment, the laser projection screen is also easily affected by the background light, which in turn will cause imaging interference, making it difficult to obtain high-quality images. The high-quality display effect, from the perspective of ergonomics, is also not conducive to the protection of the eyes, thus restricting the promotion and application of laser projection display screens in laser TVs, projectors, etc.

Embodiment 1

[0041] A method for making a laser projection screen, comprising the following steps:

[0042] In step S1, the optical mold core is processed into a microstructure of concentric circle lines from large to small by machining the surface to be processed of the raw material of the optical mold core, and is processed into a microstructure such as: figure 1 , figure 2 Microstructure shown. figure 1 It is a schematic diagram of the frontal structure of the optical mold core of a laser projection screen. It can be seen that the microstructures are concentric circles from large to small, and the angle of each concentric circle, the depth of processing, and the width of the lines are different. figure 2 It is a side structure (left side) of an optical mold core of a laser projection screen and a schematic diagram of a side structure (right side) of a semi-finished product of a laser projection screen; Preferably, in this embodiment, the optical mold core raw material material is a m...

Embodiment 2

[0054] A laser projection screen, comprising a screen backplane, the screen backplane comprising an optical plate 3 and a color-changing layer, the optical plate 3 is closely attached to the color-changing layer, and the optical plate 3 has several laser projection The light projected by the host 1 is reflected to the audience and an optical module that absorbs the interference of the background light source 4. The optical module includes a reflective surface 2 for reflecting the light projected by the laser projection to the audience, and a light absorbing surface 7 for absorbing the background light source 4 and 4. The optical glue surface, the reflective surface 2, the light absorption surface 7 and the optical glue surface form a triangular column microstructure, and several triangular column microstructures are continuously connected together to form a zigzag array, and the zigzag array is arranged in a matrix. Due to the different angles of light projected by the laser pr...

Abstract

The invention discloses a method for manufacturing a laser projection screen, which comprises the following steps: step S1, processing the surface of the optical mold core into an optical mold core with a microstructure; step S2, performing ultrasonic cleaning on the optical mold core; step S3, coating Release agent to obtain a release layer; step S4, apply optical glue on the release layer; step S5, attach an optical plate on the optical glue; step S6, perform UV curing, and obtain a coated film with a release layer , semi-finished laser projection screen of optical glue and optical plate; step S7, demoulding the semi-finished laser projection screen with the optical mold core; step S8, spraying the semi-finished laser projection screen to form a reflective surface; step S9, spraying the semi-finished laser projection screen to form a reflective surface; The semi-finished laser projection screen is baked, and the baked semi-finished laser projection screen is cut; step S10, a color-changing layer is provided on the semi-finished laser projection screen after baking, thereby manufacturing a laser projection screen. The invention also discloses a laser projection screen, which is free from background light source interference and has good imaging effect.

Description

technical field [0001] The invention relates to the field of laser projection display, in particular to a manufacturing method of a laser projection screen and a laser projection screen. Background technique [0002] At present, the traditional projection display technology on the market has low anti-interference and cannot be used in brightly lit places, and usually needs to be used in darker environments. The laser projection display technology is a new type of projection display technology on the market. Compared with the traditional projection display technology, the laser projection display has the advantages of high contrast, clear imaging, bright colors, high brightness, energy saving and environmental protection. [0003] However, the current laser projection screen manufacturing method is complicated in process, complicated in processing molds, expensive and time-consuming. In addition, when the background light such as indoor illumination light and outdoor light s...
