Description

Technical Field

[0001] The present invention belongs to the technical field of display panels, and in particular relates to a method for preparing a display panel with diversified color effects. Background Art

[0002] Metal thin film fabrication techniques include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electrochemical deposition. These techniques can form metal films with unique physical, chemical, and electrical properties on substrates. These films are widely used in optics, electronics, energy technology, and other fields.

[0003] Glass coating products currently on the market generally use a single-color film layer of uniform thickness. This monotony limits product diversity and fails to fully meet the current market demand for diverse display effects. For example, Chinese patent CN106086814A discloses a glass panel coating and its preparation method. Using MOCVD technology, a micro-nanocrystalline aluminum oxide film is deposited on the glass panel surface at high speed, with a growth temperature of 300-600°C.

[0004] The above patent is based on the function of enhancing the hardness of the glass panel and improving its scratch resistance, that is, it improves the physical properties of the substrate, and it does not contribute to the display effect of the glass panel. Summary of the Invention

[0005] To address the aforementioned technical issues, the present invention provides a method for preparing a display panel with diverse color effects. This method enables color variations in different regions of the display panel, thereby displaying a rich variety of patterns on a single substrate, satisfying the market's demand for personalized and customized display effects.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A method for preparing a display panel with diversified color effects, the method comprising the following steps:

[0008] (1) Pattern design: Design the color pattern of the display panel;

[0009] (2) Simulation: Input the refractive index data of the substrate and target used in the display panel into the MacLeod software, and then simulate the color produced by the film layer formed by the target material at different thicknesses;

[0010] (3) Cutout processing: Use graphics processing software to process the color pattern and convert it into a vector diagram. By analyzing the colors of different areas in the vector diagram, the thickness and color of the film in different areas are matched;

[0011] (4) Coating: Different thicknesses of film layers are formed in different areas according to the thickness matching the regional colors.

[0012] The substrate is any one of a glass fiber board, a metal substrate, a glass substrate, and a membrane.

[0013] The thickness of the substrate is 0.1 to 50 mm.

[0014] The shape of the substrate is a 2D plane shape or a 3D shape.

[0015] The target material is any one or more of silicon nitride, aluminum oxide, titanium oxide, aluminum nitride, metallic aluminum, silver, gold, copper, zinc, chromium, and molybdenum.

[0016] The substrate is a glass substrate; the target material is titanium oxide.

[0017] In step (4), the entire surface of the substrate is first coated, and then the thickness is adjusted in different areas according to the thickness matching the regional colors.

[0018] Furthermore, the thickness adjustment method is to use laser etching, and the thickness of the film layer in different regions can be adjusted by adjusting the parameters of the laser etching.

[0019] In step (4), different thicknesses of film layers can also be formed directly by evaporation or sputtering in different regions according to the thickness of the regional color matching. For example, a mask with a specific pattern can be placed between the substrate and the target material; the movement, rotation or tilt of the substrate can also be controlled by programming to change its relative position or angle with respect to the evaporation source, and the thickness difference of different regions can be achieved by utilizing the characteristic that the deposition rate changes with distance / angle; the local deposition rate can also be changed by dynamically adjusting parameters such as power, gas pressure, pulse frequency, etc., thereby changing the deposition thickness; any other methods disclosed in the prior art that can achieve thickness adjustment can also be used in the present invention.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention provides a method for preparing a display panel with diverse color effects. Specific areas on the surface of a glass substrate can present diverse color effects. This technology breaks through the limitations of traditional monochrome film layers and allows for close integration with display modules.

[0022] In display module applications, when the screen is active, the light it emits passes through layers of varying thickness, displaying different colors and creating a rich visual effect. Conversely, when the screen is off and no light is emitted, the pattern on the film becomes the primary visual presentation, providing users with a novel visual experience. This innovative process not only enhances the functionality of displays but also expands their design and aesthetic potential.

[0023] The present invention provides a method for preparing a display panel with diversified color effects, wherein a coating treatment is performed on the surface of a substrate, which not only improves the physical properties of the substrate but also gives it unique optical properties.
