Description

Technical Field

[0001] This utility model belongs to the field of display technology, specifically an anti-glare touch display. Background Technology

[0002] A touchscreen display, also known as a touch panel, is a sensor-based liquid crystal display device capable of receiving touch input signals. When a user touches the graphic buttons on the screen, the haptic feedback system drives various connected devices according to a pre-programmed program, thereby replacing traditional mechanical button panels and presenting vivid audio-visual effects through the liquid crystal display.

[0003] With the widespread application of touch display technology, users have increasingly higher requirements for display effects. In outdoor or bright light environments, traditional touch displays are easily affected by ambient light, resulting in glare that makes the displayed content difficult to read and negatively impacts the user experience. Existing anti-glare technologies mainly achieve this through surface coatings or special films. While anti-glare technologies (such as frosted surface coatings and anti-reflective films) can reduce reflection, they have the following drawbacks: frosted coatings reduce light transmittance, affecting display brightness and color reproduction; anti-reflective films have poor compatibility with the touch layer, easily leading to touch signal delay or drift. To address these issues, an anti-glare touch display is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-glare touch display in order to solve the problems mentioned above.

[0006] The anti-glare layer is made of a nanoscale microstructure anti-glare film, and the anti-glare layer has a subwavelength microstructure formed on its surface through nano-pressing technology. The electrodes of the touch sensing layer are embedded in the subwavelength microstructure.

[0007] In a preferred embodiment, the anti-glare layer is a composite film with a gradually changing refractive index.

[0008] In a preferred embodiment, the subwavelength microstructure of the anti-glare layer is a concave-convex array with a period of 200-500nm and a depth of 50-150nm.

[0009] In a preferred embodiment, the touch sensing layer is an integrated capacitive touch mesh structure.

[0010] In a preferred embodiment, the composite antireflective layer is composed of three layers of alternating high and low refractive index materials.

[0011] In a preferred embodiment, the edge of the protective glass layer is provided with a curved microprism structure with a radius of curvature R = 0.3-1 mm.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by embedding the touch electrode into the subwavelength microstructure of the anti-glare layer, combined with the composite anti-reflection layer and curved edge design, the ambient light reflectivity is significantly reduced (≤0.8%) while maintaining the screen's thinness, effectively improving touch accuracy and display effect.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example

[0021] This utility model provides an anti-glare touch display, see reference. Figures 1 to 3As shown, the display includes an LED display substrate 1, an anti-glare layer 2 bonded to the LED display substrate 1 with optical adhesive, a touch sensing layer 3 bonded to the anti-glare layer 2 with optical adhesive, a composite anti-reflective coating 4 bonded to the touch sensing layer 3 with optical adhesive, and a protective glass layer 5 bonded to the composite anti-reflective coating 4 with optical adhesive. The above structure constitutes an anti-glare touch display, wherein the LED display substrate 1 displays image content, the anti-glare layer 2 reflects ambient light to reduce the impact of reflected light intensity on the display effect, the touch sensing layer 3 enables touch sensing, the composite anti-reflective coating 4 further reduces the reflectivity of ambient light and improves display clarity, and the protective glass layer 5 protects the internal structure from damage.

[0022] refer to Figures 1 to 3 As shown, the anti-glare layer 2 adopts a nanoscale microstructure anti-glare film, and the anti-glare layer 2 has a subwavelength microstructure formed on its surface through nano-pressing technology. The subwavelength microstructure of the anti-glare layer 2 is a concave-convex array with a period of 200-500nm and a depth of 50-150nm. In this structure, the incident ambient light is scattered through the light diffraction effect, thereby playing the role of anti-glare.

[0023] It should be noted that the subwavelength microstructure is a concave-convex six-dimensional deformable structure.

[0024] refer to Figures 1 to 3 As shown, the electrodes of the touch sensing layer 3 are embedded in the subwavelength microstructure. The touch electrodes of this structure are embedded in the microstructure grooves of the anti-glare layer to avoid signal shielding.

[0025] refer to Figures 1 to 3 As shown, the anti-glare layer 2 is a composite film with a gradually changing refractive index, specifically a SiO2-TiO2 composite film.

[0026] refer to Figures 1 to 3 As shown, the touch sensing layer 3 is an integrated capacitive touch grid structure, wherein the grid line width is ≤5μm and the light transmittance is ≥90%. The touch sensing layer 3 adopts capacitive touch technology to support multi-touch function.

[0027] refer to Figures 1 to 3 As shown, the composite anti-reflective coating 4 is composed of three layers of high and low refractive index materials stacked alternately. The three high and low refractive index materials of the composite anti-reflective coating 4 are SiO2, Ta2O5 and MgF2, respectively. The material thickness of SiO2 is 80nm, the material thickness of Ta2O5 is 60nm and the material thickness of MgF2 is 100nm. The above structure with multiple high and low refractive index materials can optimize reflection suppression for the visible light band (380-780nm).

[0028] refer to Figures 1 to 3As shown, the edge of the protective glass layer 5 is provided with a curved microprism structure with a curvature radius R=0.3-1mm. The protective glass layer 5 is made of chemically strengthened glass, such as Corning Gorilla Glass, with a Mohs hardness ≥7. The curved microprism structure at the edge of the protective glass layer 5 mainly suppresses lateral glare.

[0029] The implementation principle of an anti-glare touch display according to an embodiment of this application is as follows: When in use, the subwavelength microstructure of the anti-glare layer 2 can scatter incident ambient light, while the composite anti-reflection coating 4 uses a variety of high and low refractive materials to optimize reflection suppression for the visible light band (380-780nm), and the electrodes of the touch sensing layer 3 are embedded in the subwavelength microstructure, thereby improving the sensitivity and response speed of touch control.
