Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a backlight with an electromagnetic film. Background Art

[0002] A backlight is one of the key components of non-self-luminous display devices such as liquid crystal displays (LCDs), and is mainly used to provide uniform background light. Traditional backlights usually use LEDs (light emitting diodes) or CCFLs (cold cathode fluorescent lamps) as light sources, and achieve uniform distribution of light through optical elements such as light guide plates and diffusion films. In recent years, with the continuous development of display technology, users have put forward higher requirements for the intelligence, fineness and interaction experience of backlights.

[0003] Traditional backlights have the following disadvantages:

[0004] 1. Insensitive to point contact effects: Traditional backlights cannot display fine image quality textures in detail, resulting in insufficiently delicate display effects, especially in scenarios that require high-precision displays (such as handwriting input, drawing, etc.).

[0005] 2. Low intelligence level: Traditional backlights lack the ability to dynamically respond to the displayed content and cannot adjust optical characteristics in real time according to user operations or display requirements.

[0006] 3. Poor human-computer interaction experience: Traditional backlights cannot support faster human-computer interaction functions, such as stroke feedback during handwriting input or dynamic display adjustment. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Referring to Figures 1-6 , a backlight with an electromagnetic film includes a backlight assembly 11. The backlight assembly 11 includes an electromagnetic film 1, a reflective film 2, an adhesive-iron integrated module 3, a light guide plate 4, a diffusion film 5, a lower brightness enhancement film 6, an upper brightness enhancement film 7, a light-shielding adhesive layer 8, an LED light-emitting module 9, and a touch sensing interface 10. The touch sensing interface 10 is integrated on the surface of the electromagnetic film 1, above or below the electromagnetic film 1, and is used to detect the user's handwriting input or touch operation and feedback the signal to the control circuit. The electromagnetic film 1 is fixedly installed between the reflective film 2 and the adhesive-iron integrated module 3. The other side of the adhesive integrated module 3 is covered with a light guide plate 4. The other side of the light guide plate 4 is fixedly installed with a diffusion film 5. The other side of the diffusion film 5 is installed with a lower brightness enhancement film 6. The other side of the lower brightness enhancement film 6 is covered and fixed with an upper brightness enhancement film 7. The other side of the upper brightness enhancement film 7 is covered with a light-shielding adhesive layer 8. The LED light-emitting module 9 is installed below the backlight assembly 11 and is located inside the adhesive integrated module 3.

[0033] Furthermore, it should be noted that the electromagnetic film 1 is made of polyimide material, and its material surface is coated with a silver ion conductive coating. It is arranged between the reflective film 2 and the adhesive-iron integrated module 3, and its optical properties (such as light transmittance, reflectivity, etc.) are adjusted by applying an external contact or electric and magnetic fields, so as to dynamically control the display fineness and interactive feedback of the backlight.

[0034] Furthermore, it should be noted that the reflective film 2 is made of polypropylene material, and its material surface is coated with a metal aluminum coating, which reflects the light source emitted by the LED component back into the backlight.

[0035] Further, it should be noted that the glue-iron integrated module 3 includes LED lamp beads, a hot melt adhesive layer, and an iron substrate. The LED lamp beads are fixedly installed on the iron substrate through the hot melt adhesive layer to ensure the backlight intensity and reflect the surrounding light sources.

[0036] Further, it should be noted that the light guide plate 4 is made of polymethyl methacrylate material and is a light source channel for the LED assembly, which is used to evenly distribute the light emitted by the light source to the entire display area.

[0037] Further, it should be noted that the diffusion film 5 is made of poly(p-xylene glycol) terephthalate material, which converts the light source in the light guide plate from a point light source to a surface light source.

[0038] Further, it should be noted that both the lower brightness enhancement film 6 and the upper brightness enhancement film 7 are made of polycarbonate material, and the brightness enhancement structure can correct the angle of the backlight source.

[0039] Further, it should be noted that the light-shielding adhesive layer 8 is composed of a PET base layer and a light-blocking layer. The light-blocking layer is made of a rubber-based adhesive, and the light-blocking layer is coated on the PET base layer to conceal the light sources scattered around the light guide plate.

[0040] Further, it should be noted that the LED lighting module 9 is composed of several LED lighting chips, and uses an LED array or a micro-LED as the light source to provide high-brightness and low-power light output.

[0041] Further, it should be noted that the electromagnetic film 1 is connected to the control circuit to solve the problems of insensitive point contact effect of the backlight source, insufficient display fineness, and poor human-computer interaction experience, and is used to adjust the working state of the electromagnetic film in real time according to user operations or display content.

[0042] Working mode: As a new type of functional material, the electromagnetic film 1 can change its optical properties through the action of external contact or electric and magnetic fields, so as to realize the dynamic regulation of the display effect of the backlight source. Applying the electromagnetic film to the backlight source can significantly improve the display fineness and support faster human-computer interaction and handwriting texture.

[0043] Working principle:

[0044] 1. The light emitted by the light source module is evenly distributed to the display area through the light guide plate 4.

[0045] 2. The electromagnetic film 1 adjusts its optical properties according to the signal of the control circuit, so as to dynamically adjust the display fineness and interaction feedback of the backlight source.

[0046] 3. When the user performs a handwriting input or a touch operation, the touch sensing layer detects the operation signal and feeds it back to the control circuit. The control circuit adjusts the working state of the electromagnetic film in real time to provide a more delicate display effect and a more real pen stroke feedback.

[0047] 4. The optical film layer further optimizes the light uniformity and brightness to ensure the display effect.

[0048] Core innovation:

[0049] Improve display fineness: By dynamically adjusting the optical properties of the backlight source through the electromagnetic film, it can display the texture of small image elements more delicately, improving the display effect. Support fast human-computer interaction: The combination of the electromagnetic film and the touch sensing layer enables faster human-computer interaction and handwriting texture, enhancing the user experience. Intelligent regulation: The control circuit adjusts the working state of the electromagnetic film in real time according to user operations or display content, realizing the intelligent regulation of the backlight source. Energy conservation and environmental protection: Through dynamic dimming and efficient light source design, the power consumption is significantly reduced, meeting the requirements of energy conservation and environmental protection.

[0050] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
