Problems solved by technology

When projecting, buildings with gravel walls have low reflectivity and poor image quality; buildings with glass curtain walls have problems with specular reflectance and high transmittance (light is refracted to the sky and transmitted to the interior of the building). In severe cases, gravel walls Buildings and glass-walled buildings image poorly or not at all

Embodiment 1

[0044] The structure of the one-way paste of the present embodiment is as follows:

[0045] Please combine Figure 1-3 It should be understood that the one-way sticker 5 of this embodiment includes a base film layer 51, an adhesive layer 52 and a bottom layer 53 bonded to each other in sequence, and a plurality of light holes 510 are arrayed on the base film layer 51. There are also a plurality of partition units 511 arrayed on the layer 51 , and the light through holes 510 and the partition units 511 are spaced apart from each other.

[0046] The single-transparent paste of the present embodiment has the characteristics of high imaging quality:

[0047] In the process of studying the optical properties of the single-transmission sticker, it was unexpectedly found that the single-transmission sticker has new characteristics of high projection imaging quality and low pixel loss. Sensory evaluations were performed by 10 panelists. According to the ten-point scale, 9-10 is goo...

Embodiment 2

[0056] The structure of the projection imaging film of the present embodiment is as follows:

[0057] Please combine Figure 4-6It should be understood that the projection imaging film 1 of the present embodiment includes a diffuse reflection coating 11, a base film layer 12, an adhesive layer 13 and a bottom layer 14 which are sequentially bonded to each other. Light holes 120, these light through holes 120 are opened on the base film layer 12, and a plurality of reflective elements 121 are also arrayed on the base film layer 12, and each light reflective element 121 is two adjacent light through holes 120 , the light holes 120 and the reflective elements 121 are spaced apart from each other.

[0058] The base film layer 12 can be made of polyethylene plastic (PE plastic for short), polyvinyl chloride plastic (PVC plastic for short), or polyterephthalic acid plastic (PET plastic for short). The diameter of the light holes 120 is 1 mm, and the distance between two adjacent l...

Embodiment 3

[0080] The projection imaging film of this embodiment has many similarities with the projection imaging film of Embodiment 1, and these similarities will not be repeated. However, please combine Figure 9 It should be understood that the difference between the projection imaging film 3 of this embodiment and the projection imaging film of Embodiment 1 is that there are a plurality of light holes arrayed on the base film layer, and these light holes are not completely aligned in rows and columns, and adjacent to each other. The light holes of the two rows are staggered from each other.

Abstract

The invention provides an application of a one-way vision and a projection imaging film in projection. The one-way vision comprises a base film layer, wherein a plurality of light through holes are arrayed in the base film layer, a plurality of separation elements are further arrayed on the base film layer, and the light through holes and the separation elements are mutually spaced. The light through holes can transmit light, so that the normal illumination intensity inside a building can be kept; and the separation elements can reflect projection light, so that the projection quality of a building glass curtain wall is improved, and accordingly, the one-way vision can meet the basic requirements of both day lighting inside the building and improvement of projection quality.

Description

technical field [0001] The invention relates to the application of a one-way sticker and a projection imaging film, in particular to an application of a one-way sticker and a projection imaging film in projection. Background technique [0002] One Way Vision (also known as one-way vision), the name of one-way vision comes from the abbreviation of "sunshade perforated one-way vision". One-way vision is made of PVC material, which is mainly suitable for pasting window , glass doors and windows, glass curtain walls or glass surfaces of vehicles (such as subway doors and windows), it can not only block sunlight, but also advertise, and is a good advertising material. The single-transparent pasted array has a circular light hole, the diameter of the light hole is 1.8mm, and the area of ​​the light hole is 2.5mm 2 , the distance between two adjacent light holes is 0.6mm. [0003] Existing single-transparent stickers are mainly suitable for "blocking sunlight and advertising", bu...
