Problems solved by technology

At present, the frame of the touch screen cover is mostly made of screen printing black and white ink, and the black and white appearance can no longer satisfy consumers' pursuit of fashion. Therefore, various frame color mobile phones are gradually favored by the public.
Although the ink has a variety of colors, the touch screen cover appears dull due to the dull luster of the ink itself

preparation example Construction

[0048] like image 3 As shown, the method for preparing a touch screen cover in one embodiment can be used to prepare the above touch screen cover. The preparation method of the touch screen cover plate of the present embodiment includes the following steps:

[0049] Step S210: coating an inorganic material on one surface of the substrate, and making the inorganic material cover the surface of the substrate to form an inorganic film.

[0050] Wherein, the substrate is a glass plate, a quartz plate, an alumina plate or a transparent organic plate. Please also refer to Figure 4 , Figure 4 is a schematic structural diagram of the substrate 300 .

[0051] The thickness of the substrate is 0.01-10 mm; preferably, the thickness of the substrate is 0.1-5 mm; more preferably, the thickness of the substrate is 0.3-2 mm.

[0052] Please also refer to Figure 5 and Figure 6 After one surface of the substrate 300 is coated with an inorganic material, an inorganic film 400 is for...

Embodiment 1

[0079] The preparation steps of the touch screen cover plate of the present embodiment are as follows:

[0080] (1) Evaporate aluminum oxide on one surface of a glass substrate with a thickness of 0.1 mm by vacuum thermal evaporation, and cover the surface of the glass substrate with the evaporated aluminum oxide to form an aluminum oxide film with a thickness of 10 microns.

[0081] (2) Screen-print heat-curing ink on the edge of the aluminum oxide film, and cure it at 100°C for 30 minutes to form an ink layer with a thickness of 1 mm along the edge of the substrate, so that the ink layer covers part of the inorganic membrane.

[0082] (3) Use the stripping agent to spray the substrate for 10 minutes to remove the inorganic film not covered by the ink layer, and the remaining inorganic film is the reflective layer. After cleaning, continue to complete the subsequent steps according to the design requirements to obtain the touch screen cover , wherein, the stripping agent inc...

Embodiment 2

[0085] The preparation steps of the touch screen cover plate of the present embodiment are as follows:

[0086] (1) Titanium dioxide is sputtered on one surface of a quartz substrate with a thickness of 5 mm by magnetron sputtering, and the surface of the substrate is covered by the sputtered titanium dioxide to form a titanium dioxide film with a thickness of 300 nanometers.

[0087] (2) Screen-print thermosetting ink along the edge of the titanium dioxide film, and cure it at 200°C for 10 minutes to form an ink layer with a thickness of 1 nanometer and along the edge of the substrate, so that the ink layer covers part of the inorganic film .

[0088] (3) Soak the substrate in a stripping tank filled with a stripping agent, soak for 0.5 to 10 minutes under ultrasonic conditions with an intensity of 60KHz, remove the inorganic film that is not covered by the ink layer, and the remaining inorganic film is the reflective layer , after cleaning, continue to complete the follow-u...

Abstract

The invention relates to a touch screen cover plate and a manufacturing method thereof. The touch screen cover plate comprises a substrate, a reflecting layer, and an ink layer. The reflecting layer is formed on one surface of the substrate. The reflecting layer is arranged on the periphery of the edge of the substrate. The reflecting layer is a metal elemental film or a compound film. The compound film is one selected from an oxide film, a fluoride film, a zinc sulfide film, a zinc selenide film, a titanium nitride film, a silicon carbide film, a lanthanum titanate film, a barium titanate film, a strontium titanate film, a praseodymium titanate film, and a cadmium sulfide film. The ink layer is on the reflecting layer, and the ink layer can reflect light which passes through the reflecting layer back to the reflecting layer. The touch screen cover plate has relatively high reflectivity, so glossiness of the touch screen cover plate is good.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen cover plate and a preparation method thereof. Background technique [0002] With the popularization of smart phones and tablet computers, the manufacturing process of touch screens (Touch Panel) has been continuously improved, and the capacitive touch screen cover has become the current mainstream. At present, the frame of the touch screen cover is mostly made of screen printing black and white ink, but the black and white appearance can no longer satisfy consumers' pursuit of fashion. Therefore, mobile phones with various frame colors are gradually favored by the public. Although the ink has a variety of colors, the touch screen cover appears dull due to the dull luster of the ink itself. Contents of the invention [0003] In view of this, it is necessary to provide a touch screen cover with better gloss. [0004] In addition, a preparation method of the touch scr...
