Description

Technical Field

[0001] The utility model belongs to the technical field of touch screens, and particularly relates to an anti-glare touch screen. Background Art

[0002] With the popularization of mobile devices (such as smart phones and tablet computers), touch screens have become one of the main ways of human-computer interaction. Touch screen technology has gone through multiple stages from early resistive touch screens to current capacitive touch screens. Capacitive touch screens have become the mainstream due to their high sensitivity and multi-touch capabilities. In actual use, touch screens often encounter glare problems. Especially in outdoor or strong light environments, the light reflected by the screen will seriously affect the user's visual experience. Glare not only causes visual fatigue but also reduces the readability of the screen content.

[0003] Although traditional anti-reflection coatings can reduce reflection to a certain extent, there will still be obvious reflection phenomena at specific wavelengths. Especially at certain specific angles, the reflected light will still affect the user's line of sight; existing anti-glare films can reduce glare, but sometimes they will cause a decrease in screen resolution and affect visual clarity. In addition, the matte treatment may lose its effect after long-term use, resulting in wear on the screen surface; many touch screens perform differently under different lighting conditions. Especially at night or in low-light environments, the overly bright screen will cause discomfort to the eyes. And in strong light, the insufficient screen brightness makes it difficult to see the content clearly.

[0004] In view of the above problems, the utility model provides an anti-glare touch screen to solve the above problems. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides an anti-glare touch screen, including:

[0007] An anti-reflection coating, provided on the outermost layer of the touch screen;

[0008] An anti-glare film, provided below the anti-reflection coating;

[0009] A microstructural texture layer, located below the anti-glare film;

[0010] A touch sensing layer, provided below the microstructural texture layer;

[0011] A display panel, provided below the touch sensing layer;

[0012] A backlight adjustment module, provided below the display panel.

[0013] The present utility model is further configured such that the anti-reflection coating includes multiple layers of materials with different refractive indices, and the thickness of each layer is an odd multiple of a quarter wavelength.

[0014] The present utility model is further configured such that the anti-glare film contains abrasive materials, and the particle size of the abrasive materials is 1 to 5 microns.

[0015] The present utility model is further configured such that the microstructural texture layer includes a series of micron-scale conical structures, the bottom diameter of the conical structures is 2 to 10 microns, and the height is 1 to 5 microns.

[0016] The present utility model is further configured such that the backlight adjustment module includes an ambient light sensor, and the ambient light sensor can detect the ambient light intensity in real time and transmit a signal to the control system to adjust the backlight brightness.

[0017] The present utility model is further configured to further include an edge sealing layer, and the edge sealing layer surrounds the entire perimeter of the touch screen.

[0018] The present utility model is further configured to further include an anti-fingerprint coating, and the anti-fingerprint coating is provided on the anti-reflection coating.

[0019] The present utility model is further configured to further include at least one interface, and the interface is used to connect external devices or a power source.

[0020] The present utility model has the following beneficial effects:

[0021] 1. Through the setting of the anti-reflection coating, the present utility model can significantly reduce the reflection of ambient light on the surface of the touch screen, thereby improving the clarity of the screen and the user's visual experience. Especially in a strong light environment, the user can see the screen content more clearly. Combining with the application of the anti-glare film, while reducing glare, it maintains a good touch and operation experience of the touch screen, making the user's eyes not easily fatigued during long-term use.

[0022] 2. Through the setting of the microstructural texture layer, the present utility model can further improve the visual effect of the screen without affecting the display quality. Especially when observing from different angles, it can reduce the reflection spots, making the image more uniform. The ambient light sensor added in the backlight adjustment module can automatically adjust the screen brightness according to the change of the surrounding light, which not only provides better adaptability visually but also saves energy consumption and extends the service life of the device. The addition of the anti-fingerprint coating can keep the screen surface clean under frequent contact, reducing the attachment of fingerprints and other stains, and facilitating the user's daily cleaning and maintenance.

[0023] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. Brief Description of the Drawings

[0031] Embodiment

[0032] Please refer to Figures 1-3 , the present invention is an anti-glare touch screen, including:

[0033] Anti-reflection coating 1, provided on the outermost layer of the touch screen;

[0034] Anti-glare film 2, provided below the anti-reflection coating 1;

[0038] The backlight adjustment module 6 is disposed below the display panel 5;

[0039] The edge sealing layer 7 surrounds the perimeter of the entire touch screen.

[0040] The anti-fingerprint coating 8 is disposed on the anti-reflection coating 1.

[0041] At least one interface 9 is connected to an external device or a power source.

[0042] Specifically, the anti-reflection coating 1 includes multiple layers of materials with different refractive indices, and the thickness of each layer is an odd multiple of a quarter wavelength; the anti-glare film 2 contains abrasive materials, and the particle size of the abrasive materials is 1 to 5 micrometers; the micro-structured texture layer 3 includes a series of micron-scale conical structures, the bottom diameter of the conical structures is 2 to 10 micrometers, and the height is 1 to 5 micrometers; the backlight adjustment module 6 includes an ambient light sensor, and the ambient light sensor can detect the ambient light intensity in real time and transmit a signal to the control system to adjust the backlight brightness.

[0043] The detailed description of the anti-glare touch screen proposed by this technical solution is as follows:

[0044] The anti-reflection coating 1 uses multiple layers of transparent materials with different refractive indices, such as silicon dioxide, strontium titanate, or other suitable optical thin film materials. The thickness of each layer is an odd multiple of a quarter wavelength of the incident light wavelength, which helps to reduce the reflected light through the interference effect, thereby improving the light transmittance and screen clarity, and optimizing the anti-reflection effect under different light sources.

[0045] The anti-glare film 2 contains abrasive materials, such as tiny glass beads or plastic particles, to scatter light and reduce the glare caused by direct light. The particle size of the abrasive materials is 1 to 5 micrometers, and such a size can effectively disperse light without affecting the touch accuracy.

[0046] The micro-structured texture layer 3 includes a series of micron-scale conical structures. The bottom diameter of these structures is 2 to 10 micrometers, and the height is 1 to 5 micrometers. Without significantly affecting the resolution, it can further improve the visual comfort, reduce the surface reflection, increase the viewing angle range, and enable the screen to maintain good visibility at various angles.

[0047] The touch sensing layer 4 uses resistive, capacitive, or other types of touch technologies, specifically depending on the application requirements. The display panel 5 uses LCD, OLED, or other display technologies, specifically also depending on the application requirements.

[0048] The ambient light sensor built in the backlight adjustment module 6 can detect the intensity of the surrounding ambient light in real time. Based on the data of the ambient light sensor, the control system will automatically adjust the backlight brightness to achieve the best visual effect while saving energy.

[0049] The edge sealing layer 7 is made of materials with strong weather resistance, such as silica gel, polyurethane, etc., to protect the internal components from the influence of external environmental factors (such as dust and water vapor).

[0050] The anti-fingerprint coating 8 is an oleophobic and hydrophobic substance, such as a fluoride coating, which can effectively prevent fingerprint residues, reduce stains, and facilitate cleaning and maintenance.

[0051] The interface 9 is used to connect other devices or for charging to ensure the normal operation of the touch screen as an independent device or as part of an embedded system.
