[0020] Panel 100 with anti-fog coating, cover plate 101, anti-fog layer 102, display module 200, display screen 201, backlight assembly 202. Detailed Implementation

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0022] This application discloses a panel 100 coated with an anti-fog layer; please refer to [link / reference]. Figure 1 The system includes a cover plate 101 and an anti-fog layer 102. The cover plate 101 includes a display side and a backlight side, which are opposite sides of the cover plate 101. The anti-fog layer 102 is coated on the display side of the cover plate 101. In environments with high humidity or large temperature differences between the inside and outside of the cover plate 101, the anti-fog layer 102 makes the surface of the cover plate 101 appear clear. It utilizes hydrophilic groups on the anti-fog layer 102 to adsorb water and reduce the surface tension of the water, thus reducing the contact angle between water molecules and objects. Before water forms droplets, it diffuses or adsorbs onto the surface of the anti-fog layer 102, forming an ultra-thin transparent water film, thereby achieving an anti-fog effect. Furthermore, the unformed water droplets do not scatter incident light from the outside, do not interfere with the user's view, and make it easy for the user to view the data on the screen.

[0023] It should be noted that the cover plate 101 is a transparent glass sheet. The cover plate 101 includes a non-visible area and a visible area. The non-visible area surrounds the edge of the visible area. The visible area is used to display the image, while the non-visible area covers other components under the cover plate 101. The anti-fog layer 102 is a silane compound. For example, silane coupling agent KH-310 can be used as a glass anti-fog agent. It is an alkylsilane, chemically named hexadecyltrimethoxysilane, soluble in many organic solvents. Anti-fog agents are low-molecular-weight dispersants containing hydrophilic groups, composed of molecules with a defined molecular weight. When applied to the surface of a transparent object, it forms a coating. The hydrophilic groups in the coating adsorb water molecules from the air, wetting and diffusing them on the surface of the transparent cover plate 101 to form a water film (not water droplets), preventing light scattering and avoiding fogging.

[0024] Preferably, the thickness of the anti-fog layer 102 is 1µm. The thinness results in minimal change in the overall volume of the product and does not affect the design of the blister pack, etc.

[0025] Please refer again. Figure 1 This application also proposes a display module 200, including the aforementioned panel 100 coated with an anti-fog layer, display screen 201, and backlight assembly 202. The backlight side of the anti-fog layered panel 100, the display screen 201, and the backlight assembly 202 are connected sequentially. The backlight assembly 202 provides illumination for the display screen 201, and the anti-fog layered panel 100 protects the display screen 201. It has an anti-fog function, and the water film on the anti-fog layered panel 100 does not scatter incident light from the outside, thus not interfering with the user's view and making it easy for the user to view the data on the screen. Preferably, the display screen 201 is an AMOLED screen.

[0026] In one embodiment, the backlight assembly 202 includes a light source assembly, a backlight panel, and a light guide assembly. The backlight panel is used to fix / limit the light source assembly and the light guide assembly. The light source assembly is disposed on the backlight panel, and the light guide assembly is disposed on the same side as the light source assembly. The light emitted by the light source assembly is guided out through the light guide assembly.

[0027] Furthermore, the light source component consists of multiple LED beads, which are evenly spaced on the backlight panel. The driving current range of the LED beads is 5mA-25mA. The current range can be adjusted according to the actual brightness required by the display screen 201, so that the display screen 201 achieves the brightness required by the user.

[0028] Furthermore, the display module 200 also includes a first polarizer and a second polarizer, which are disposed on opposite sides of the display screen 201. The first polarizer is disposed on the side of the display screen 201 away from the backlight assembly, and the second polarizer is disposed on the side of the display screen 201 away from the cover plate 101. The first and second polarizers work together to remove excess reflections from the display screen 201, enhancing image contrast and clarity. When this display module 200 is applied to a handheld device or tablet computer, the first and second polarizers are primarily used to control sunlight reflection on the screen.

[0029] In one embodiment, the display module 200 further includes OCA adhesive. The backlight side of the cover plate 101 is bonded to the first polarizer using OCA adhesive, and then to the display screen 201 using OCA adhesive. The OCA adhesive is colorless and transparent with a light transmittance of over 90%, exhibiting extremely strong light transmittance, thus not affecting the backlight illumination of the display screen 201. The display screen 201 and the second polarizer are also bonded together using OCA adhesive.

[0030] In addition, the light guide assembly includes a reflective sheet, a light guide plate, an upper brightness enhancement film, a lower brightness enhancement film, a diffuser film, and a backlight FPC. LED beads are disposed on the side of the backlight plate and are electrically connected to the backlight FPC. The reflective sheet, light guide plate, diffuser film, lower brightness enhancement film, and upper brightness enhancement film are stacked sequentially and disposed within the accommodating space of the backlight plate. The reflective sheet abuts against the backlight plate, and the light emitted by the LED beads is reflected by the reflective sheet to the light guide plate. The backlight FPC is bent and fixed to the backlight plate. Light passes sequentially through the light guide plate, diffuser film, lower brightness enhancement film, and upper brightness enhancement film. The light guide plate converts the point light source of the LED beads into a surface light source for uniform illumination. The upper and lower brightness enhancement films concentrate the diffused light emitted by the LED beads in the front direction to increase brightness. The diffuser film diffuses the light, making the light more uniformly illuminated, and the reflective sheet enhances the brightness of the light.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
