Description

Technical Field

[0001] This utility model belongs to the field of multi-layer stacked display technology, and specifically relates to a structure with multi-layer stacked display function. Background Technology

[0002] Currently, mainstream side-emitting display modules primarily use a single-layer color filter + light-blocking foam material + side-emitting light guide plate for interface interaction. This technology requires light-blocking material between the light guide plates to prevent light leakage. In this mode, when the light guide plate emits light, the projection of the light causes the display interface to show black lines, resulting in each touch area icon being displayed independently. Furthermore, the display interface uses thick or thin black lines to distinguish each area, failing to demonstrate interface integrity. To address these bottlenecks, this invention proposes a structure with multi-layer stacked display functionality. Utility Model Content

[0003] The purpose of this invention is to provide a structure with multi-layer stacked display function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a structure with multi-layer stacked display function, comprising a multi-layer stacked display module, wherein the multi-layer stacked display module is composed of a color filter, an upper light-blocking layer, an upper light guide plate, an optical film, a lower light-blocking layer, a lower light guide plate, a PCB and its electronic component layer, wherein the color filter, upper light-blocking layer, upper light guide plate, optical film, lower light-blocking layer, lower light guide plate, PCB and its electronic component layer are arranged sequentially from top to bottom.

[0005] Preferably, the color filter has multiple function key areas and a background image, wherein the background image is laid out across the color filter.

[0006] Preferably, the upper light-blocking layer is specifically assembled at the bottom of the color filter and is used for light blocking of the upper light guide plate.

[0007] Preferably, the upper light guide plate is provided with multiple clearance areas, which correspond to the function key areas; wherein: the upper light guide plate adopts two forms in the corresponding function key areas: one with optical dots and one without optical dots, and with an edge aperture structure to effectively suppress light crosstalk; at the same time, the upper light guide plate is equipped with a color film and adopts regional dimming technology to enable independent control of function icons and areas other than icons, so that different areas of the same film on the upper layer can be displayed together or separately, thereby achieving various display effects.

[0008] Preferably, the surface of the optical film has multiple light-transmitting areas, which correspond to the function key areas. The bottom of the optical film has connecting ribs and partition grooves that match the lower light-blocking layer. The light-transmitting areas can be made of perforated structures, transparent materials, or other light-transmitting materials. The light-transmitting areas are dynamically adjusted according to the materials, refractive indices, and installation tolerances of the upper and lower light guide plates. The graphic structure of the light-transmitting areas is consistent with the pattern structure of the function key areas on the color filter to ensure light collimation.

[0009] Preferably, the lower light-blocking layer is provided with an embedded light guide plate fixing groove, which matches the lower light guide plate, wherein: the depth of the embedded light guide plate fixing groove is greater than the thickness of the lower light guide plate; both the upper and lower light-blocking layers are composed of flexible materials, have toughness, and have a stress-buffering connecting rib structure design.

[0010] Preferably, the lower light guide plate is provided with multiple independent light guide plates, each corresponding to a light-transmitting area. Specifically, the lower light guide plate adopts a modular array layout, with each function button area configured with an independent light guide plate. Each lower light guide plate uses high-density dots at the corresponding color film function button area to enhance reflection efficiency, thereby improving button brightness and providing high contrast to the button area. Furthermore, a lower light-blocking layer separates the upper and lower light guide plates, allowing for independent control of both layers. The upper light guide plate illuminates areas other than icons, while the lower light guide plate illuminates function icons. When the product is in operation, both layers can be illuminated simultaneously, providing high contrast between the function buttons and the background, allowing customers to easily distinguish button functions.

[0011] Preferably, the PCB and its electronic component layer are provided with multiple light sources, and the light sources are set at different heights according to the position and pattern of the independent light guide plate, wherein: the height of the lower layer of the light source is 0.4-1.2mm; and the height of the upper layer is 0.6-3mm.

[0012] The technical effects and advantages of this utility model are as follows: This structure, through a dual-layer independent display architecture, allows the icons and the graphics outside the icons to be integrated together, and enables both the icons and the graphics outside the icons to be controlled independently, presenting a superior display effect without black lines blocking light. It achieves optical matching between the functional area and the non-functional area within a single module, and has three core advantages compared to traditional single-layer display modules: 1. Enhanced Functional Integration: The innovative dual-layer light guide system can simultaneously display function buttons and background information, achieving a more aesthetically pleasing integrated display effect; 2. Visual experience optimization: Combining color gamut zoning control and gradient optical isolation technology, the human-computer interface achieves a visual performance at the level of professional monitors.

[0013] 3. It offers a more prominent user interface application for market customers, enhancing the core competitiveness of the product. Attached Figure Description

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

[0017] This utility model provides, for example Figure 1-17 The diagram shows a structure with multi-layer stacked display functionality, including multi-layer stacked display modules; Specifically, the multi-layer stacked display module consists of a color filter 101, an upper light-blocking layer 102, an upper light guide plate 103, an optical film 104, a lower light-blocking layer 105, a lower light guide plate 106, a PCB and its electronic component layer 107, which are arranged sequentially from top to bottom.

[0018] Specifically, the color filter 101 is provided with multiple function key areas 301 and background image 302, wherein the background image 302 is laid out on the color filter 101.

[0019] Specifically, the upper light-blocking layer 102 is assembled at the bottom of the color filter 101 and is used for light blocking of the upper light guide plate 103.

[0020] Specifically, the upper light guide plate 103 is provided with multiple clearance areas 303, wherein the clearance areas 303 correspond to the function key areas 301; wherein: the upper light guide plate 103 adopts two forms in the corresponding function key areas 301, either with or without optical dot design, and in conjunction with the edge aperture structure, effectively suppresses light crosstalk; at the same time, the upper light guide plate 103 is equipped with a color film 101, which adopts regional dimming technology, so that the function icons and the areas outside the icons can be independently controlled, and different areas of the same film on the upper layer can be displayed together or separately, thereby achieving a variety of display effects.

[0021] Specifically, the surface of the optical film 104 is provided with multiple light-transmitting areas 304, which correspond to the function key areas 301. The bottom of the optical film 104 is provided with connecting ribs and partition grooves that match the lower light-blocking layer 105. The light-transmitting areas 304 can be made of perforated structures, transparent materials, or other light-transmitting materials. The light-transmitting areas 304 are dynamically adjusted according to the materials, refractive indices, and installation tolerances of the upper light guide plate 103 and the lower light guide plate 106. The graphic structure of the light-transmitting areas 304 is consistent with the pattern structure of the function key areas 301 on the color film 101 to ensure light collimation.

[0022] Specifically, the lower light-blocking layer 105 is provided with an embedded light guide plate fixing groove, which matches the lower light guide plate 106. The depth of the embedded light guide plate fixing groove is greater than the thickness of the lower light guide plate 106. Both the upper light-blocking layer 102 and the lower light-blocking layer 105 are composed of flexible materials and have toughness, and have a stress-buffering connecting rib structure design.

[0023] Specifically, the lower light guide plate 106 is provided with multiple independent light guide plates 305, each corresponding to a light-transmitting area 304. The lower light guide plate 106 adopts a modular array layout, with each function button area configured with an independent light guide plate 305. Each lower light guide plate 106 uses high-density dots at the corresponding function button area 301 of the color film 101 to enhance reflection efficiency, thereby improving button brightness and providing high contrast to the button area. A lower light-blocking layer 105 separates the upper light guide plate 103 and the lower light guide plate 106, allowing for independent control of the two light guide plates. The upper light guide plate 103 illuminates areas other than icons, while the lower light guide plate 106 illuminates function icons. When the product is in operation, both layers can be illuminated simultaneously, providing high contrast between the function buttons and the background, allowing customers to easily distinguish button functions.

[0024] Specifically, the PCB and its electronic component layer 107 are provided with multiple light sources 306. The light sources 306 are set at different heights according to the position and pattern of the independent light guide plate 305, wherein: the lower layer height of the light source 306 is 0.4-1.2mm; the upper layer height is 0.6-3mm. Example

[0025] Traditional display modules such as Figure 4-6 As shown, the display consists of a traditional color filter 201, a traditional light-blocking layer 202, a traditional light guide plate 203, and a traditional PCB and its electronic component layer 204. These components are arranged sequentially from top to bottom. The traditional color filter 201 only contains function key displays; other areas are either completely black or completely white. The traditional light-blocking layer 202 is a flexible material used to block light from the upper colored layer or the background illumination. The traditional light guide plate 203 uses a dot array arrangement, resulting in uniform light emission without brightness adjustment. The light sources within the traditional PCB and its electronic component layer 204 are all positioned at the same height to illuminate the pattern. In this mode, when the light guide plate emits light, the display interface shows black lines due to the projection of the light, causing each touch area icon to be displayed independently. Furthermore, the display interface uses thick or thin black lines to distinguish each display area, failing to reflect the integrity of the interface. In this structure, a background image 302 is added inside the color film 101 to display the entire image. The upper light-blocking layer 102 is made of a flexible material and is used to block the light from the upper color transmission or background illumination. An upper light guide plate 103 and a lower light guide plate 106 are added. The upper light guide plate 103 has a void area 303, which is used to create voids or sparse areas in the dot arrangement, allowing for a smooth transition of the pattern. The optical film 104 has a light-transmitting area 304. The bottom is supported by connecting ribs and a partition groove to cooperate with the lower light-blocking layer 105. The lower light-blocking layer 105 has an embedded light guide plate fixing groove to cooperate with the lower light guide plate 106. The lower light guide plate 106 adopts an independent light guide plate 305, and the light field is isolated by a lower light-blocking layer 105 between the upper light guide plate 103 and the lower light guide plate 106. This allows for independent control of the two light guide plates. At the same time, the light sources 306 on the PCB and its electronic component layer 107 are not at the same height. The appropriate height of the light source 306 is selected according to the pattern illuminating different areas. Through the dual-layer independent display architecture, the icons and the graphics outside the icons can be integrated together, and the icons and the graphics outside the icons can be controlled independently, presenting a better display effect without light-blocking black lines.
