Description

Repair type screen

Technical Field

The utility model relates to the field of projection screens, in particular to a repairing type screen.

Background

With the development of technologies such as high frame rate, high resolution, high dynamics, wide color gamut shooting technology and high power high brightness laser projection, the cinema and other related industries gradually need giant screens with areas as high as hundreds of square meters or even larger giant screens, and huge screen pictures can bring obviously better visual effect and good immersive experience, but also bring the processing problem that the screen is locally damaged: for example, the local damage of the screen is easily caused by careless touching or scratching of the screen by the audience, careless direct touching of the screen by a cleaner during cleaning or liquid spraying of the screen, the touching of the screen by a bug and the like. The existing solution is to replace the whole huge screen, which causes huge resource waste, huge workload and huge cost loss.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to overcoming the disadvantages and drawbacks of the prior art and providing a touch-up screen that ameliorates or solves the above problems.

The purpose of the utility model is realized by the following technical scheme: a touch-up screen comprising: the original screen comprises an original screen base material and an original screen reflecting surface; the replacement screen is positioned in front of the original screen and provided with a chamfer or a fillet, and comprises a replacement screen base material and a replacement screen reflecting surface; an adhesive positioned between the original screen and the replacement screen.

Further, the method also comprises the following steps: the screen base material is adhered to the back of the original screen damage area through an adhesive and is used for enhancing the strength of the screen.

Further, the thickness of the edge of the replacement screen after chamfering or rounding is 0.01-0.4 mm.

Further, the thickness of the edge of the replacement screen after chamfering or rounding is 0.01-0.05 mm.

Furthermore, the original screen and the replacement screen have the same surface reflection material and reflection layer structure.

Further, the original screen and the replacement screen have the same brightness coefficient, effective scattering angle, contrast, color reduction performance and color temperature difference.

Further, the adhesive is double-sided adhesive tape or glue.

Further, the shape of the replacement screen is rectangular or circular.

Furthermore, the original screen and the replacement screen respectively comprise a substrate layer, a crystal arrangement layer, a crystal dense superposition layer, a coating angle light-gathering layer, a crystal gain spraying layer, an individual crystal gain structure layer, a reflective gain layer and a surface protection layer.

Compared with the prior art, the utility model can effectively solve the problem of repairing the locally damaged screen and avoid the problem that the whole screen, especially a huge screen, needs to be replaced if the locally damaged screen is slightly damaged.

Detailed Description

The present invention will be further described with reference to fig. 1 and 2.

As shown in fig. 1, a touch-up screen of the present embodiment includes: 1, an original screen 10, wherein the original screen 10 comprises an original screen base material 12 and an original screen reflecting surface 11; 2, replacing the screen 20, wherein the replacing screen 20 comprises a replacing screen base material 22 and a replacing screen reflecting surface 21; 3, adhesive 30. As shown in fig. 2, the repairing step is a, determining a damaged area of an original screen (S100); B. cutting a replacement screen base material with the area not smaller than the area of the original screen damaged area and chamfering or filleting the edge of the base material (S200); C. spraying or printing a reflecting layer on the base material of the replacement screen, the reflecting layer being the same as the original screen (S300); D. the replacement screen is pasted with an adhesive and covers the damaged area of the original screen (S400).

Taking a cinema as an example, the screen area of the current cinema is generally as high as hundreds of square meters or even larger, but the screen is a vulnerable product (the screen comprises a screen substrate and a screen reflecting surface, and the reflecting surface of the screen cannot be made into a very hard surface because of good optical performance, so the reflecting surface is a surface which is easy to damage actually), and phenomena that the audience, especially small children touch or scratch the screen carelessly, a cleaner directly touches the screen carelessly or sprays liquid on the screen when cleaning, and insects touch the screen frequently occur, and the phenomena that the screen is locally damaged are caused. If the whole giant screen is replaced, huge resource waste, huge workload and huge cost loss are caused. The distance from the first row of the cinema to the screen is usually about 5 meters to 10 meters, and the larger the screen is, the larger the distance between the screen and the first row is. At the distance, human eyes cannot feel or feel very little about well-processed tiny patchwork traces, and the current screen surface particles become thinner and smaller than the screen surface particles in the past (many screens with a microcrystalline structure or a nano structure are already a multilayer microcrystalline screen or a multilayer microcrystalline screen comprising a substrate layer, a crystal arrangement layer, a crystal dense superposition layer, a coating angle light-gathering layer, a crystal gain spraying layer, an individual crystal gain structure layer, a reflection gain layer and a surface protection layer), so that the local damage of the screen is repaired in a repairing mode innovatively. Firstly, the damaged area of the original screen 10 is confirmed through personnel observation or instrument observation, then a replacement screen base material which is not smaller than the area of the damaged area of the original screen is cut, the edge of the base material is chamfered or rounded, then a reflecting layer which is the same as that of the original screen is sprayed or printed on the base material of the replacement screen, and then the replacement screen is adhered by an adhesive and covers the damaged area of the original screen. The left side of the replacement screen 20 of fig. 1 is chamfered and the right side is not chamfered, and it can be seen by comparison that the non-chamfered side has a significantly higher cutting edge and a significantly higher protruding structure. Therefore, the repair marks can be optimized obviously by proper chamfering (for example, the repair marks are very difficult to be found by a viewer with the thickness of 0.2 mm after chamfering, and the repair marks can not be found by the viewer if the thickness of 0.1 mm or even 0.05 mm can be reached). In addition, if a certain edge of the replacement screen is above and above the height of the viewer, this edge does not need to be chamfered.

Generally, the replacement screen and the original screen should be identical or highly uniform, such as the replacement screen and the original screen both having the same surface reflection material and reflection layer structure, the same brightness coefficient, effective scattering angle and contrast, and the same color reduction performance and color temperature difference. The preferred shape of the replacement screen is rectangular, but if the damaged area is circular or a circular-like structure, a circular replacement screen may be used. The replacement screen is then glued and covers the damaged area of the original screen by glue or double sided tape. For the original screen with damage, a layer of screen base material can be adhered to the back of the damaged area of the original screen through an adhesive to strengthen the strength of the screen.

The foregoing is a more detailed description of the utility model in connection with specific preferred embodiments and it is not intended that the utility model be limited to these specific details. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
