Technical Field
[0001] This utility model belongs to the field of automotive interior parts technology, and in particular to a luminous interior parts system with transparent display function. Background Technology
[0002] With the increasing demand for intelligent and personalized vehicles, automotive interior design is gradually evolving from single-function to multi-functional integration. Currently, automotive interior lighting and display systems typically employ a separate design, with lighting functions mostly using traditional LED light strips, while information display relies on a separate screen. This design not only occupies a large space but also lacks overall aesthetic appeal.
[0003] In the field of transparent display technology, transparent organic light-emitting diode (TOLED) displays have already seen some applications as an emerging technology. German company Loewe first used it in its "Loewe Invisio" invisible television product in May 2012. OLED transparent screens, with their backlight-free structure, can achieve high transparency, but their application in automotive interiors still faces many challenges.
[0004] In the existing technology, Chery Automobile Co., Ltd. has obtained a patent entitled "A Crystal Illuminated Interior Part" (authorization announcement number CN222937666U). This technology includes components such as an interior panel, a light-transmitting film, a light-diffusing plate, a light-concentrating plate, and a circuit board with LED beads, which can achieve a crystal lighting effect. However, this technical solution is limited to providing decorative lighting effects and lacks information display functions, thus failing to meet the needs of modern intelligent vehicles for interactive information display.
[0005] Traditional LED displays rely on arrays of light-emitting diodes as the light source, achieving uniform illumination through backlight modules or side-lit light guides. Even with advanced packaging technologies such as Mini / Micro LED, their display logic remains an "additive operation," modulating light through liquid crystal layers or color filters. This architecture sacrifices some transparency, making it difficult to simultaneously achieve high transparency and high-quality display effects. Furthermore, existing internal light-emitting components typically cannot dynamically adjust the displayed content and brightness according to ambient light and user needs, resulting in poor visibility under varying lighting conditions.
[0006] Therefore, there is an urgent need for a new interior component technology that can organically combine transparent display function with luminous decorative effect to solve problems such as the separation of display and lighting functions, the difficulty in balancing transparency and display quality, and the lack of intelligent interaction capabilities in existing technologies. Utility Model Content
[0007] In view of the above problems, the purpose of this utility model is to provide a luminous interior component system with transparent display function. Through the innovative combination design of light source protection structure and light-transmitting material, it effectively solves the problem of light source damage, while achieving a high-definition transparent display effect, enhancing the texture and technological feel of the car interior, and providing users with a richer, more natural and interactive visual experience, thereby overcoming the shortcomings of the above-mentioned prior art.
[0008] This utility model provides a light-emitting interior component system with transparent display function, including a transparent substrate assembly, a display driver, a transparent light-emitting component, and a functional stack-up assembly;
[0009] The transparent substrate assembly includes: a silicon-based transparent display layer composed of a first silicon substrate and a second silicon substrate, and a liquid crystal layer located between the first silicon substrate and the second silicon substrate;
[0010] The display driver is a thin-film transistor array integrated on a first silicon substrate;
[0011] The functional stacked assembly includes, from the inside out, a reflective layer, a color layer, a contour layer, a light guide plate layer, a diffuser sheet, and a protective layer, wherein the protective layer is located on the side closest to the second silicon substrate;
[0012] The transparent light-emitting component includes a side-lit Mini LED light strip and a quantum dot enhancement film. The side-lit Mini LED light strip is embedded in the side edge of the transparent light-emitting component and is attached to the light guide plate layer. The light is then passed through the diffuser, color layer and contour layer in sequence through the light guide plate layer, and finally forms uniform light on the silicon-based transparent display layer.
[0013] As a preferred embodiment of this invention, the thickness of both the first silicon substrate and the second silicon substrate is 0.6 mm.
[0014] As a preferred embodiment of this invention, the pixel density of the thin-film transistor array is 300-500 PPI.
[0015] As a preferred embodiment of this invention, the quantum dot reinforced film is a fine dot film formed on its surface by laser dotting, with a dot density of 50-80 dots / mm. 2 It is used to control the direction of light propagation.
[0016] As a preferred embodiment of this invention, the reflective layer and diffuser sheet are PET (polyethylene terephthalate) films, the color layer and contour layer are PC films printed with multiple layers of ink, and the two are superimposed to create a three-dimensional pattern effect. The light guide plate layer is a PMMA (acrylic or plexiglass) sheet, and the protective layer is a transparent sealing layer (using UV-cured adhesive).

By optimizing the layered structure and material selection, this utility model solves the problems of insufficient brightness, blurry images and complex structure that exist when traditional luminous interior parts are combined with transparent display technology, and realizes that automotive interior parts can maintain a beautiful luminous effect while having a high-definition information display function.

[0022] See Figure 1 As shown, this embodiment provides a light-emitting interior component system with transparent display function, including: a transparent substrate assembly 1, a display driver 2, a transparent light-emitting component 3, a functional stacked assembly 4, and a control circuit board 5; the transparent substrate assembly 1 includes: a silicon-based transparent display layer composed of a first silicon substrate 101 and a second silicon substrate 102, and a liquid crystal layer 103 located between the first silicon substrate 101 and the second silicon substrate 102; the thickness of the first silicon substrate 101 and the second silicon substrate 102 is 0.6 mm, the light transmittance is ≥85%, and it has high mobility characteristics. The display driver 2 is a thin-film transistor (TFT) array 201 integrated on the first silicon substrate 101; the TFT array 201 has a pixel density of 300-500 PPI and is manufactured using low-temperature polycrystalline silicon (LTPS) technology. The functional stacked component 4 includes, from the inside out, a reflective layer 401, a color layer 402, a contour layer 403, a light guide plate layer 404, a diffuser 405, and a protective layer 406, with the protective layer 406 located on the side closest to the second silicon substrate 102; the transparent light-emitting component 3 includes a side-lit Mini LED light strip and a quantum dot enhancement film, the quantum dot enhancement film being a fine dot film formed on the surface by laser dotting, with a dot density of 50-80 dots / mm. 2The side-lit Mini LED light strip is embedded in the side edge of the transparent light-emitting component 3. It is attached to the light guide plate layer 404, and the light is sequentially guided through the diffuser 405, color layer 402, and contour layer 403 via the light guide plate layer 404, ultimately forming uniform light on the silicon-based transparent display layer. The color layer 402 achieves approximately 130% NTSC color gamut coverage. The control circuit board 5 includes an integrated PWM dimming module and an image processing chip. The image processing chip is electrically connected to the side-lit Mini LED light strip via the integrated PWM dimming module, and is connected to the vehicle's central control system via a CAN bus.
[0023] In this embodiment, the reflective layer 401 and the diffuser sheet 405 are PET (polyethylene terephthalate) films, the color layer 402 and the contour layer 403 are PC films printed with multiple layers of ink, and the two are superimposed to create a three-dimensional pattern effect. The light guide plate layer 404 is a PMMA (acrylic or plexiglass) sheet, and the protective layer 406 is a transparent sealing layer (using UV-curable adhesive).
[0024] Working principle: The transparent substrate assembly serves as the main structure. The lower surface of the light guide plate is laser-drilled to form a precise dot pattern with a dot density of 50-80 dots / mm. 2 It is used to control the direction of light propagation; after passing through the light guide plate, the light passes through the diffuser, color layer, and contour layer in sequence, finally forming a uniform light emission effect on the transparent substrate. When information needs to be displayed, the control circuit board activates the TFT array in the corresponding area, and controls the light transmittance by adjusting the arrangement of liquid crystal molecules to achieve the transparent display function. The non-display area maintains a high light transmittance state, while the display area presents the desired image, realizing the dual function of "displaying an image when displaying and being transparent when not displaying".
[0025] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
