It should be understood that the drawings are not only used to explain and illustrate the present utility model, but also help to define the present utility model when necessary. DETAILED DESCRIPTION

[0026] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are only exemplary of specific ways to implement and use the present invention, rather than limiting the scope of the present invention.

[0027] In this document, when describing the structural position of various components, "front side" refers to the surface facing the observer, such as Figure 1 and Figure 2 The left side surface of each layer in the display component of the display assembly; "back side" refers to the surface facing away from the observer, such as Figure 1 and Figure 2 The right side surfaces of the layers in the display component.

[0028] It can be understood that the arrangement position of the display component according to the present invention in the vehicle is not restrictive. The display component can be integrated into the vehicle's dashboard, auxiliary dashboard, seat backs, door panels, seat armrests, ceiling and other vehicle interior components (i.e., interior trims), and can also be arranged at any other location where information needs to be displayed for display and interactive use.

[0029] Figure 1 It is a cross-sectional schematic diagram of a first embodiment of a display assembly according to the utility model.

[0030] like Figure 1 As shown, the display assembly mainly includes a decorative film 11, a transparent cover plate 12, an optical adhesive layer 13, a display unit 10 and a light source 14 which are arranged in sequence.

[0031] like Figure 3As shown, according to one embodiment, the decorative film 11 includes a transparent base layer 111, a light shielding layer 112 located on the transparent base layer 111, an ink texture layer 113 located on the light shielding layer 112, and a protective layer 114 located on the texture layer 113, wherein the light shielding layer 112 and the texture layer 113 are provided with a plurality of light-transmitting holes. More specifically, after the texture layer 113 is applied to the light shielding layer 112, the texture layer 113 and the light shielding layer 112 are punched together to form a plurality of light-transmitting holes. When the display unit 10 at the rear is turned off, the texture layer 113 of the decorative film 11 will be clearly visible under the irradiation of the external ambient light. When the display unit 10 at the rear is turned on, the light can pass through these light-transmitting holes to reach the outermost surface of the product to display a pattern on the texture.

[0032] It is understandable that the diameter and arrangement density of these light-transmitting holes determine the transmittance of the decorative film 11. For example, these light-transmitting holes are micropores with a diameter between 15 μm and 80 μm, and the transmittance is preferably set between 20% and 45%. If the transmittance is lower than 20%, although the decorative effect is good, the light loss is too high, and a very high-brightness display light source is required, resulting in high power consumption and heat dissipation difficulties. If the transmittance is higher than 45%, although the light loss is small and a very high-brightness display light source is not required, the decorative texture will be lighter and the decorative effect will be poor. Therefore, the transmittance range of 20%-45% ensures the best decorativeness and display effect.

[0033] In the first embodiment, the transparent cover plate 12 is, for example, injected onto the entire back side of the decorative film 11 by the IML (in-mold molding) process to form an integral part with the decorative film 11. The transparent cover plate 12 provides support and strength for the decorative film 11, while protecting the display unit 10 behind. The decorative film 11 and the transparent cover plate 12 are integrally injection molded by the IML process, eliminating the complicated bonding process and materials that would be required if optical adhesive was used to bond the decorative film 11 and the transparent cover plate 12, thereby reducing the product thickness and cost. It is understandable that the transparent cover plate 12 can be constructed as a flat surface or a curved surface with any curvature in order to match the specific shape of the vehicle interior, so that the integral part formed by the decorative film 11 and the transparent cover plate 12 has a flat or curved shape as a whole.

[0034] The display unit 10 is attached to the back of the integrated piece, for example, by laminating the integrated piece with the optical adhesive layer 13, more specifically, vacuum laminating the back of the transparent cover plate 12. The type of optical adhesive is not restrictive, for example, it can be OCA (transparent tape) or OCR (liquid transparent adhesive). After laminating, the area of ​​the decorative film 11 and the transparent cover plate 12 facing the display unit 10 constitutes a display area, and the other areas outside the display area constitute a non-display area.

[0035] like Figure 4 As shown, when the display unit 10 is turned off, no pattern is displayed, and the texture of the entire decorative film 11 is clearly visible under the illumination of external ambient light. Figure 5 As shown, when the display unit 10 is lit, the light of the display unit 10 can reach the outermost surface of the product to display a pattern (such as the displayed vehicle speed information, power information, etc.) on the texture of the display area. Therefore, the display component of the present invention eliminates the boundary and gap between the display area and the non-display area through this concealable display technology, thereby improving the user's viewing experience.

[0036] It is understandable that in the first embodiment, the area on the back of the decorative film 11 that does not overlap with the display unit 10 (i.e., the non-display area on the back of the decorative film 11) or the area on the back of the transparent cover 12 that does not overlap with the display unit 10 (i.e., the non-display area on the back of the transparent cover 12) is provided with a light shielding layer to prevent the non-display area from being exposed. The position of the light shielding layer in the hierarchical structure depends on the requirements for the surface effect, and the light shielding layer can be realized by screen printing, curved surface printing or UV (ultraviolet) printing according to the shape of the decorative film 11 or the transparent cover 12 and the desired effect.

[0037] The display unit 10 is, for example, a liquid crystal panel (LCD panel) or a fixed beacon pattern. Preferably, the display unit 10 is an RGBW (red, green, blue, and white) liquid crystal panel. It is very advantageous to use RGBW liquid crystal panels in concealable display technology, because each pixel of the RGBW panel has an additional white light sub-pixel, which improves the light output efficiency, so its transmittance is about three times that of a conventional RGB (red, green, and blue) panel, and the power consumption of the product is lower when the brightness is equal. The low transmittance of the decorative film 11 is offset by a high-transmittance RGBW panel, thereby ensuring that the display brightness requirements can still be met without increasing power consumption and heat. For example, the transmittance of conventional RGB panels is generally 3%. When the surface brightness requirement is 800 nit, the backlight brightness must reach 95,000 nit to meet the requirement. After testing, a 3.1-inch edge-entry backlight must reach a brightness of 95,000 nit and power consumption is 10.5 W. The transmittance of the RGBW panel is 9%. When the surface brightness is 800 nit, the backlight brightness only needs 31,000 nit and power consumption of 3.5 W to meet the requirement.

[0038] The light source 14 is arranged on the back of the display unit 10, which is, for example, a fixed lamp box, a side-lit backlight module, or a direct-lit partitioned LED (light-emitting diode) backlight module (including a mini-LED backlight module and a micro-LED backlight module). Here, "the side-lit backlight module is arranged on the back of the display unit 10" is understood as: the side-lit backlight module includes a light guide plate opposite to the back of the display unit 10 and light-emitting components arranged around the side of the light guide plate, and the light emitted by the light-emitting components enters the light guide plate from the side and then emits toward the back of the display unit 10 to illuminate the display unit 10. According to a variant embodiment, the light source 14 can be integrated into the display unit 10, that is, the display unit 10 itself can emit light without an additional backlight source. In this case, the display unit 10 is, for example, an OLED (organic light-emitting diode) panel or an LED display matrix (including a mini-LED display matrix and a micro-LED display matrix). "Mini" means millimeter level, and "micro" means micrometer level.

[0039] For a display unit 10 that is not self-luminous, if the light source 14 adopts a side-lit backlight module, a frame effect is likely to occur after the display unit 10 is turned on, that is, the boundary of the display unit 10 is likely to be visible. Therefore, in this case, the light shielding layer arranged on the back side of the decorative film 11 or the back side of the transparent cover plate 12 preferably extends inward (that is, toward the back side of the decorative film 11 or the transparent cover plate 12 and the area overlapping with the center of the display unit 10) to include a transition area overlapping with the boundary of the display unit 10, and the transition area is configured to gradually increase its transmittance inward (for example, the printed ink gradually becomes lighter, or the density or diameter of the light-transmitting holes gradually increases), so as to weaken the display boundary of the display unit 10 after it is turned on.

[0040] Figure 2 1 is a cross-sectional schematic diagram of a second embodiment of the display assembly according to the utility model. The overall structure of the display assembly according to the second embodiment is similar to that of the first embodiment, so the similarities are not described again, except that the transparent cover plate 12 is injection molded on the entire front surface of the decorative film 11 to form an integral piece with the decorative film 11. That is, the transparent cover plate 12 is located at the outermost side of the product in the second embodiment, and the display unit 10 is vacuum-bonded to the back surface of the decorative film 11, for example, through the optical adhesive layer 13.

[0041] It can be understood that, in this case, a shading layer can be provided on the back side of the decorative film 11 in the area that does not overlap with the display unit 10 (i.e., the non-display area on the back side of the decorative film 11) to prevent the non-display area from being exposed, while the shading layer cannot be provided on the back side of the transparent cover plate 12.

[0042] In fact, the positions of the decorative film 11 and the transparent cover plate 12 can be determined according to the surface decoration requirements. If it is necessary to make a depth of field decorative effect where the decorative texture is under the transparent part, the decorative film 11 is arranged to be located on the back of the transparent cover plate 12. If the decorative surface needs to be exposed or the decorative surface needs to have a certain tactile feel, the decorative film 11 is arranged to be located on the front of the transparent cover plate 12. The display clarity of the solution with the decorative film 11 on the back of the transparent cover plate 12 is better than the display clarity of the decorative film 11 on the front of the transparent cover plate 12 (the closer the decorative film 11 is to the display unit 10, the higher the display clarity), and there is no difference between the two in terms of display concealment.

[0043] The technical content and technical features of the utility model have been disclosed above. However, it can be understood that under the creative idea of ​​the utility model, technicians in this field can make various changes and improvements to the above-disclosed concepts, but they all belong to the protection scope of the utility model.
