Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a chromatic aberration compensation method and a chromatic aberration compensation system for a transparent display wall, which can enhance the transparent display effect and improve the visual attractiveness.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
FIG. 1 is a flowchart of a chromatic aberration compensation method for a transparent display wall according to the present invention. As shown in fig. 1, a method for compensating chromatic aberration of a transparent display wall includes:
step 101: the method comprises the following steps of attaching transparent glass to a chromatic aberration compensation film, wherein the chromatic aberration compensation film comprises a plurality of rectangular areas with the same size, a first light transmittance is obtained outside the range of the rectangular areas, a second light transmittance is obtained within the range of the rectangular areas, and the first light transmittance is lower than the second light transmittance; each rectangular area corresponds to the size and position of the display area of the transparent display screen.
Step 102: and (5) attaching the attached color difference compensation film to the transparent display screen. The chromatic aberration compensation film is attached to the transparent display screen through optical cement.
FIG. 2 is a schematic view of the structure of the transparent display wall according to the present invention. As shown in fig. 2, the transparent display wall of the present invention includes: the color difference compensation film comprises transparent glass 1, a color difference compensation film 2 and a transparent display screen 3, wherein the color difference compensation film 2 is attached to the transparent display screen 3 through optical cement 4.
The chromatic aberration compensation film 2 is made of a polymer substrate material, and the material itself has a certain light absorption (gray film), and the absorption outside the window area is stronger than that inside the window (for example, different absorbent doping concentrations are controlled in the manufacturing process). Or a layer of material with light absorption can be coated or printed on the surface of the material.
The transparent display screen 3 adopts a transparent OLED display screen or a transparent LED display screen or a transparent LCD display screen.
The transparent glass 1 is divided into an area A and an area B, and the chromatic aberration compensation film 2 corresponding to the area A and the area B is also divided into the area A and the area B. The light transmittance of the color difference compensation film 2 is determined by the light transmittance of the transparent display screen 3. The light transmittance of the transparent display screen 3 is designed and controlled, the light transmittance of the transparent display screen 3 exposed in the air is T, the light transmittance of the chromatic aberration compensation film 2 in the area B is T0, if the display screen is fixed on glass in a frame attaching mode, the light transmittance of the chromatic aberration compensation film 2 in the area A is T0T, and if the display screen is fixed on glass in a full attaching mode, the light transmittance of the chromatic aberration compensation film 2 in the area A is calculated by additionally considering the reflectivity change caused by the reduction of the interface refractive index gradient after attaching.
For example, the refractive indexes of the surface material of the transparent display panel 3, the chromatic aberration compensation film 2 and the optical adhesive 4 are all approximately 1.5, and then, according to the fresnel reflection formula, each interface causes about 4% of light loss (only considering the case of normal incidence), the transmittance of a in the chromatic aberration compensation film 2 may be set to T0 × T/0.92, which is slightly higher than the frame attaching manner.
The computational expression of the fresnel formula for normal incident light reflectance is such that:
where R represents the rate at which 0 degree (front) incident light is reflected, and n1 and n2 represent the refractive indices of the media on both sides of the interface, respectively.
If full lamination is adopted, since the optical cement 4 is filled between the transparent glass 1 and the chromatic aberration compensation film 2 and between the chromatic aberration compensation film 2 and the transparent display screen 3, the optical cement 4 originally exists on the interface between the transparent glass 1 and the air (1.5-1)2/(1.5+1)24% reflection is eliminated, and also 4% reflection at the transparent display 3 and air interface is eliminated, so that the net transmission of all the components stuck together in the area B is T0*(T/(1-0.04))*(TG/(1-0.04)), divided by the transmittance T of the glass in region AGThe transmittance T0 × T/0.92 that the chromatic aberration compensation film 2 should have in the region a is obtained.
Similarly, if the index of refraction is only 1.4, then the single interface reflectivity is (1.4-1)2/(1.4+1)22.8%, the chromatic aberration compensation film 2 in the region a should have a transmittance T0 × T/0.945 at this time.
Corresponding to the chromatic aberration compensation method of the transparent display wall, the invention also provides a chromatic aberration compensation system of the transparent display wall, which comprises the following steps:
the first attaching module 201 is used for attaching the transparent glass to a chromatic aberration compensation film, the chromatic aberration compensation film comprises a plurality of rectangular areas with the same size, a first light transmittance is arranged outside the rectangular areas, a second light transmittance is arranged within the rectangular areas, and the first light transmittance is lower than the second light transmittance.
And a second attaching module 202, configured to attach the attached color difference compensation film to the transparent display screen.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the system disclosed by the embodiment, the description is relatively simple because the system corresponds to the method disclosed by the embodiment, and the relevant points can be referred to the method part for description.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
