Description

Screen damage repairing method

Technical Field

The invention relates to the field of projection screens, in particular to a maintenance technology of a giant screen of a cinema.

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 of local damage of the screens at the same time: for example, people watching the film, especially children, may accidentally hit the screen, a cleaner may accidentally hit the screen directly during cleaning, insects or mice may bite the screen, and the like, which may cause partial damage to the screen. The existing solution is to replace the whole huge screen, which causes huge resource waste, huge workload and huge cost loss.

Disclosure of Invention

It is an object of the present invention to address the deficiencies and drawbacks of the prior art and to provide a screen maintenance technique to ameliorate or solve the above problems.

The purpose of the invention is realized by the following technical scheme: a screen damage repairing method is characterized by comprising the following steps: A. determining an original screen damage area; B. the replacement screen is stuck on the back of the original screen damaged area by using an adhesive, and the reflecting surface of the replacement screen faces outwards.

Further, the step a further includes: the shape of the damaged area is trimmed to a regular rectangular shape.

Furthermore, the replacement screen and the original screen both 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 original screen and the replacement screen are microcrystalline structure screens or nano structure screens.

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

Further, the replacement screen and the original screen have the same multilayer microcrystalline structure or the same multilayer nano structure.

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

Furthermore, the original screen and the replacement screen 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.

Furthermore, the original screen and the replacement screen comprise a substrate layer, a metal reflecting layer, a crystal dense overlapping layer and a surface protective layer.

Compared with the prior art, the method can effectively solve the problem of repairing the local damage of the screen, and avoid the problem that the whole screen, especially a huge screen, needs to be replaced if the local damage is slight.

Detailed Description

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

As shown in fig. 1, a screen repairing method 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 to determine the damaged area of the original screen (S100) and then to stick the replacement screen to the back of the damaged area of the original screen with the reflective surface of the replacement screen facing outward (S200).

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, particularly small children collide the screen carelessly, a cleaner directly collides the screen carelessly when cleaning, and insects or mice bite the screen, often occur, and the phenomena can cause local damage of the screen. 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 human observation or instrument observation, and then the replacement screen 20 with the area not smaller than the damaged area is manufactured or cut, generally, the replacement screen and the original screen should be the same or highly consistent, for example, the replacement screen and the original screen both have the same surface reflection material and reflection layer structure, have the same brightness coefficient, effective scattering angle and contrast, and have the same color reproduction performance and color temperature difference. The preferred shape of the replacement screen is rectangular, but a circular replacement screen may be used if the damaged area is circular or similar circular in configuration. Then the replacement screen is stuck on the back of the original screen damaged area by using an adhesive, and the reflecting surface 21 of the replacement screen is outward facing to the reflecting surface 11 of the original screen. Further, the shape of the damaged area may also be trimmed to a regular rectangular shape to make the repaired area less visible.

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