Problems solved by technology

It is true that the surface treatment of the display panel must also meet sufficient firmness conditions, because the touch screen often causes the surface treatment layer to be worn out due to repeated fingers swipe on the display panel during use, and it is even inevitable to be scratched by fingernails, thus Affect the normal use effect
[0005] With the continuous improvement of anti-glare requirements for display panels, among the above two anti-glare methods, no matter which method is adopted, a single anti-glare method cannot meet the display requirements. The actual use requirements of the panel, so the current development trend is to adopt multiple anti-glare measures at the same time

Embodiment 1

[0061] As embodiment one, the implementation steps of the present invention are as follows:

[0062] 1). Make a rough microstructure on the surface of the ordinary hard optical glass coating film with a refractive index of 1.52, and specifically take the way of frosting, that is, utilize the small damage effect of the sharp hard particles of corundum on the glass surface, so that the glass surface produces the present invention. the desired microstructure. The Chinese grade of corundum is W10, and the obtained parameters of the microstructure are: the average diameter of the microstructure is 9 microns, and the average depth of the microstructure is 3 microns. Parametric test inspection with surface profilometer.

[0063] 2). Nickel-chromium alloy 80Ni20Cr absorbing film is plated on the microstructure. The complex refractive index of the 80Ni20Cr alloy film of the present invention is listed in Table 1 below, and its optimized physical thickness is 4.7nm. The rate is about ...

Embodiment 2

[0073] As a second embodiment of extended promotion and application, if the requirements for the firmness of the display panel can be appropriately reduced, the low refractive index film of the anti-scattering film can be made of magnesium fluoride (MgF 2 ) instead of silicon dioxide (SiO 2 ), due to MgF 2 The refractive index in the visible light region is 1.38, which is higher than that of SiO 2 The refractive index of 1.46 is lower, so that lower reflection scattering can be expected.

[0074] The implementation steps of the second embodiment are basically similar to those of the first embodiment.

[0075] 1). Exactly the same as Example 1.

[0076] 2). The nickel-chromium alloy 80Ni20Cr absorbing film is plated on the microstructure. The complex refractive index of the 80Ni20Cr alloy film is also the same as that in Table 1. The optimized physical thickness is 6.06nm, and the average transmittance corresponding to 420-680nm in the visible light region is about 48% (if ...

Abstract

The invention discloses a display panel with multiple anti-dazzle functions. The display panel comprises a substrate and a multilayer film. The substrate is common hard optical glass, and the multilayer film is composed of an absorption film and an anti-scattering film. A rough microstructure is manufactured on the surface of the hard optical glass substrate, the average diameter of the microstructure is 9 microns, and the average depth of the microstructure is 3 microns. The absorption film is an 80Ni20Cr alloy film, the complex refractive index of the absorption film is 2.0-i3.45, and the thickness of the absorption film is 4.7 nm. The anti-scattering film is composed of a titanium dioxide film and a silicon dioxide double-layer film, the refractive index of the titanium dioxide film is 2.44, and the thickness of the titanium dioxide film is 22.72 nm; the refractive index of the silicon dioxide film is 1.46, and the thickness of the silicon dioxide film is 92.24 nm. In the plating process of the multi-layer film, strong ion beams are adopted for assisting bombardment, the beam pressure is 1000 V, and the beam current is 1000 mA. The temperature of the substrate is 280 DEG C when the multilayer film is coated. The multi-anti-dazzle display panel can be normally used under strong background light.

Description

technical field [0001] The invention relates to a display panel with multiple anti-glare functions, which can effectively eliminate the glare of the display panel under a strong light background and improve the image contrast and clarity of the display panel. The technical field mainly belongs to the category of thin film optics. Background technique [0002] Today, display systems such as mobile phones, cameras, computers, ATM machines, and various vehicle-mounted and airborne head-up displays and navigation instruments are inseparable from display panels. Display panels are a very common and extremely important way to realize human-machine information exchange. medium. [0003] Unfortunately, these display systems often need to be used under strong light backgrounds such as sunlight, and at this time they will inevitably be troubled by glare. The strong light in the surrounding background will reduce the contrast and clarity of the information displayed on the display pa...
