[Technical Field]

[0001] This disclosure relates to a decorative component and a vehicle, and more particularly to a decorative component including a liquid crystal panel, and a vehicle including said decorative component. [Previous Technology]

[0002] With the development of technology, the proportion of electronic products in vehicles is constantly increasing, and in addition to emphasizing vehicle functions, attention is also paid to vehicle appearance design. However, vehicles and their exterior parts, such as headlights, turn signals, brake lights, and windows, must be designed to comply with traffic regulations before the vehicle style is implemented. Therefore, designing vehicles and their exterior parts that comply with traffic regulations and have recognizability and aesthetics has become a difficult task.

[0003] Based on the above, in today's market for vehicles and their exterior parts or decorative components, there is an urgent need to develop an exterior part or decorative component that can improve recognizability and aesthetics, and save costs and reduce design and manufacturing complexity. [Summary of the Invention]

[0004] This disclosure provides a decorative component and a vehicle. The decorative component includes a main board structure and a liquid crystal panel. The main board structure is transparent and includes a first main board surface and a second main board surface. The first main board surface and the second main board surface are disposed opposite to each other. The liquid crystal panel includes a first liquid crystal surface and a second liquid crystal surface. The first liquid crystal surface and the second liquid crystal surface are disposed opposite to each other. The first liquid crystal surface is connected to at least a portion of the second main board surface. The liquid crystal panel is flat or bent only along a first direction, thereby improving the manufacturing yield and reliability of the decorative component, and at the same time making the liquid crystal pattern of the liquid crystal panel have a distortion-free effect.

[0005] According to one embodiment of the present disclosure, a decorative component is provided, comprising a motherboard structure and a liquid crystal panel. The motherboard structure is transparent and includes a first motherboard surface and a second motherboard surface, which are disposed opposite to each other. The liquid crystal panel includes a first liquid crystal surface and a second liquid crystal surface, which are disposed opposite to each other, and the first liquid crystal surface is connected to at least a portion of the second motherboard surface. The decorative component has a motherboard side and a liquid crystal side, the first motherboard surface faces the motherboard side, the second liquid crystal surface faces the liquid crystal side, and the liquid crystal panel is flat or bent only along a first direction.

[0006] In an embodiment of the decorative component described above, the decorative component may further include an optically transparent adhesive, through which the first liquid crystal surface is indirectly connected to at least a portion of the second motherboard surface.

[0007] In the embodiment of the decorative component described above, when the liquid crystal panel is switched to a pattern mode and a first light from a first light source is used to incident on the decorative component from the surface of the first motherboard, a liquid crystal pattern of the liquid crystal panel can be observed by an observer located on the motherboard side.

[0008] In the embodiment of the decorative component described above, the first light rays sequentially pass through a first corresponding point on the surface of the first motherboard and a second corresponding point on the surface of the second motherboard, and the radii of curvature of the first corresponding point and the radii of curvature of the second corresponding point may be different.

[0009] In the embodiment of the decorative component described above, when the liquid crystal panel is switched to a transparent mode and a second light from a second light source is incident on the decorative component from the second liquid crystal surface, the second light source can be observed by an observer located on the motherboard side.

[0010] In the embodiments of the decorative components described above, the liquid crystal panel may include two transparent substrates facing the motherboard side and the liquid crystal side, respectively.

[0011] In the embodiments of the decorative component described above, the second motherboard surface, the first liquid crystal surface and the second liquid crystal surface may be parallel to each other and not parallel to the first motherboard surface.

[0012] According to another embodiment of this disclosure, a vehicle is provided, having an outer side and including a mainboard structure and a liquid crystal panel. The mainboard structure is transparent and includes a first mainboard surface and a second mainboard surface, the first mainboard surface and the second mainboard surface being disposed opposite to each other, and the first mainboard surface facing and exposed to the outer side of the vehicle. The liquid crystal panel includes a first liquid crystal surface and a second liquid crystal surface, the first liquid crystal surface and the second liquid crystal surface being disposed opposite to each other, and the first liquid crystal surface being connected to at least a portion of the second mainboard surface. The liquid crystal panel is flat or curved only along a first direction.

[0013] In the vehicle embodiment described above, when the vehicle is in a specific state, the liquid crystal panel switches to a pattern mode. When the liquid crystal panel switches to pattern mode and a first light source sequentially illuminates the motherboard structure and the liquid crystal panel from the outside, a liquid crystal pattern on the liquid crystal panel can be observed by an observer located on the outside.

[0014] In the vehicle embodiment of the foregoing implementation, the specific state may be before the vehicle is powered off, when the vehicle is stopped, or when the liquid crystal panel does not need to provide a light transmission characteristic.

[0015] In the vehicle embodiment described above, the vehicle may further include: a temperature sensor adjacent to the liquid crystal panel and used to provide a sensed temperature. When the sensed temperature is greater than a transition temperature of the liquid crystal panel and then less than the transition temperature of the liquid crystal panel, the liquid crystal panel re-sends a pattern signal corresponding to the liquid crystal pattern.

[0016] In the vehicle embodiment described above, the mainboard structure may be a lamp housing, and the vehicle may further include a second light source, which is a lamp source located inside the mainboard structure and the liquid crystal panel. When the vehicle is in motion, the liquid crystal panel switches to a transparent mode. When the liquid crystal panel switches to a transparent mode and a second ray of light from the second light source sequentially enters the liquid crystal panel and the mainboard structure, the second light source is used to be observed by an observer located on the outside.

Implementation Method

[0019] Several embodiments of this disclosure will now be described with reference to the drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the disclosure. That is, these practical details are not essential in the embodiments of this disclosure. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner; and repeated elements may be represented by the same number.

[0020] Furthermore, the terms "first" and "second" are used only to describe different components and do not limit the components themselves. Therefore, the first component can also be referred to as the second component. Moreover, the combination of components in this article is not a combination that is generally known, conventional, or familiar in this field. Whether the components themselves are familiar cannot be used to determine whether their combination relationship is easily completed by someone with ordinary knowledge in the technical field.

[0021] Figure 1A shows a perspective view of a portion of the decorative component 100 according to the first embodiment of this disclosure. Referring to Figure 1A, the decorative component 100 includes a motherboard structure 110 and a liquid crystal panel 130, and only a portion of the decorative component 100 is shown in Figure 1A.

[0022] Figure 1B shows a cross-sectional view along section line 1B-1B in Figure 1A, and Figure 1C shows a cross-sectional view along section line 1C-1C in Figure 1A. Referring to Figures 1B and 1C, the motherboard structure 110 is transparent and includes a first motherboard surface 111 and a second motherboard surface 115, which are disposed opposite to each other. The liquid crystal panel 130 includes a first liquid crystal surface 131 and a second liquid crystal surface 135, which are disposed opposite to each other, and the first liquid crystal surface 131 is connected to at least a portion of the second motherboard surface 115.

[0023] Referring to Figures 1A to 1C, the decorative component 100 has a mainboard side s1 and a liquid crystal side s2. The first mainboard surface 111 faces the mainboard side s1, and the second liquid crystal surface 135 faces the liquid crystal side s2. The liquid crystal panel 130 is either flat or bent only along a first direction x1. This improves the manufacturing yield and reliability of the decorative component 100, while ensuring that the liquid crystal pattern 137 of the liquid crystal panel 130 has a distortion-free effect.

[0024] Specifically, in the first embodiment, the liquid crystal panel 130 of the decorative component 100 is bent only along the first direction x1, and not along the second direction y1 and the third direction z1, wherein the first direction x1, the second direction y1 and the third direction z1 are perpendicular to each other. It should be noted that, since the liquid crystal panel 130 is curved, the first direction x1, the second direction y1 and the third direction z1 are different depending on their positions on the liquid crystal panel 130. For example, the first direction x1, the second direction y1 and the third direction z1 indicated in Figures 1A to 1C are based on the center point of the first liquid crystal surface 131 and the center point of the second liquid crystal surface 135.

[0025] In detail, the liquid crystal panel 130 may be a cholesteric liquid crystal panel. Thus, the cholesteric liquid crystal panel possesses both transparent / transmissive and reflective properties, which is beneficial for application in decorative components 100 or exterior parts (such as automotive exterior parts), thereby enhancing aesthetics, style, and personal style.

[0026] The decorative component 100 may further include an optical clear adhesive (OCA) 120, through which the first liquid crystal surface 131 is indirectly connected to at least a portion of the second motherboard surface 115. Thereby, the liquid crystal panel 130 and the motherboard structure 110 are fully bonded together with the optical clear adhesive 120 (direct bonding) to optimize the optical quality of the decorative component 100.

[0027] Referring to Figures 1B and 1C, when the liquid crystal panel 130 switches to a pattern mode (i.e., a reflection mode) and a first ray 811 of a first light source 810 is incident on the decorative component 100 from the first motherboard surface 111, the liquid crystal pattern 137 (not shown) of the liquid crystal panel 130 can be observed by an observer 900 located on the motherboard side s1. Here, the first light source 810 can be ambient light, and the decorative component 100 reflects and displays a specific liquid crystal pattern 137 by switching the liquid crystal panel 130 to the pattern / reflection mode.

[0028] The first ray 811 of the first light source 810 passes sequentially through a first corresponding point 112 on the first motherboard surface 111 and a second corresponding point 116 on the second motherboard surface 115. The radii of curvature of the first corresponding point 112 and the second corresponding point 116 may be different. Thus, the decorative component 100 may include a non-planar motherboard structure 110, such as a vehicle lamp housing (lamp cover), which is often a non-planar structure. In this case, the liquid crystal panel 130 is curved (flexible), and the structure of the vehicle lamp housing can take optical design into account, thereby correcting the image that the observer 900 can observe. In other embodiments according to this disclosure (not shown in the figures), the liquid crystal panel and the second motherboard surface of the motherboard structure are bent along a first direction, and the first motherboard surface of the motherboard structure is bent along a second direction, so as to perform image correction in the second direction through the optical design of the motherboard structure. When ambient light enters the decorative component from the motherboard structure, it undergoes two optical refractions using the motherboard structure and the liquid crystal panel, causing the liquid crystal pattern observed by the observer to present a special effect.

[0029] The radius of curvature of the second corresponding point 116 can be greater than the radius of curvature of the first corresponding point 112 (as shown in Figures 1B and 1C). The radius of curvature of the second corresponding point 116 on the second motherboard surface 115 is approximately equal to the radius of curvature of the corresponding point (not shown) on the first liquid crystal surface 131 of the liquid crystal panel 130 and the radius of curvature of the corresponding point (not shown) on the second liquid crystal surface 135. Therefore, when the motherboard structure 110 is a vehicle lamp housing, since lamp housings are mostly shell-shaped designs, the outer side of the lamp housing is designed to conform to the aesthetics and aerodynamics of the vehicle body, while the inner side of the lamp housing is designed with the optical reflection and refraction path of the vehicle lamp light to achieve the optical refraction effect of the inner side of the lamp housing. Therefore, generally speaking, only the optical path of the vehicle lamp light from the inside out needs to be considered. When the LCD panel 130 switches to pattern mode and two rays (not shown) from the first light source 810 are used to illuminate the decorative component 100 from the first motherboard surface 111, the first LCD surface 131 into which the two rays are incident is convex and is reflected to the outside of the vehicle. As the structure and thickness of the lamp housing change, a slightly magnified image effect can be maintained, thereby saving lamp housing costs and making the LCD pattern 137 observed by the observer 900 magnified.

[0030] When the liquid crystal panel 130 switches to a transparent mode and a second ray of a second light source (e.g., the second ray 322 of the second light source 320 in Figure 3) is incident on the decorative assembly 100 from the second liquid crystal surface 135, the second light source can be observed by an observer 900 located on the motherboard side s1. In this way, the liquid crystal panel 130 can selectively present a transmissive state, thereby expanding the application scenarios of the liquid crystal panel 130.

[0031] When the LCD panel 130 is switched to transparent mode, the light transmittance of the LCD panel 130 can be greater than or equal to 50%. In this way, the second light source can sufficiently penetrate the decorative component 100 to meet the application requirements when the LCD panel 130 is switched to transparent mode. For example, when the main board structure 110 is a vehicle lamp housing, the LCD panel 130 in transparent mode helps to maintain the driving lighting function and comply with regulations.

[0032] The liquid crystal panel 130 may include two transparent substrates (not shown in the figure), which face or are directed toward the motherboard side s1 and the liquid crystal side s2, respectively, that is, the liquid crystal panel 130 does not have a black background. In this way, the decorative component 100 and its liquid crystal panel 130 can be made of transparent materials such as glass, PET, PI, etc. (but not limited to these) and have flexible characteristics.

[0033] The second motherboard surface 115, the first liquid crystal surface 131, and the second liquid crystal surface 135 can be parallel to each other but not parallel to the first motherboard surface 111. In this way, by bonding the second motherboard surface 115 to the first liquid crystal surface 131 and matching the curvature of the first liquid crystal surface 131 to the first motherboard surface 111, the display quality of the liquid crystal pattern 137 can be improved.

[0034] The motherboard structure 110 may have a non-uniform thickness, for example, in Figures 1B and 1C, the central area of ​​the motherboard structure 110 is thicker while the upper and lower areas are thinner, and this disclosure is not limited thereto. In this way, image correction can be performed through the optical design (structural design) of the motherboard structure 110 to ensure that the liquid crystal pattern 137 observed by the observer 900 has an undistorted effect.

[0035] Figure 2A shows a perspective view of a portion of the decorative component 200 according to the second embodiment of this disclosure. Referring to Figure 2A, the decorative component 200 includes a motherboard structure 210 and a liquid crystal panel 230, and only a portion of the decorative component 200 is shown in Figure 2A.

[0036] Figure 2B shows a cross-sectional view along section line 2B-2B in Figure 2A, and Figure 2C shows a cross-sectional view along section line 2C-2C in Figure 2A. Referring to Figures 2B and 2C, the motherboard structure 210 is transparent and includes a first motherboard surface 211 and a second motherboard surface 215, which are disposed opposite to each other. The liquid crystal panel 230 includes a first liquid crystal surface 231 and a second liquid crystal surface 235, which are disposed opposite to each other, and the first liquid crystal surface 231 is connected to at least a portion of the second motherboard surface 215.

[0037] Please refer to Figures 2A to 2C. The decorative component 200 has a motherboard side s1 and a liquid crystal side s2. The first motherboard surface 211 faces the motherboard side s1, the second liquid crystal surface 235 faces the liquid crystal side s2, and the liquid crystal panel 230 is specifically a flat plate.

[0038] In detail, the liquid crystal panel 230 is a cholesteric liquid crystal panel. The decorative component 200 further includes an optically transparent adhesive 220 through which the first liquid crystal surface 231 is indirectly connected to at least a portion of the second motherboard surface 215.

[0039] Please refer to Figures 2B and 2C. When the liquid crystal panel 230 is switched to a pattern mode (i.e., reflection mode) and a first light 811 of a first light source 810 is used to incident on the decorative component 200 from the first motherboard surface 211, the liquid crystal pattern 237 (not shown) of the liquid crystal panel 230 can be observed by an observer 900 located on the motherboard side s1.

[0040] When the liquid crystal panel 230 switches to a transparent mode and a second ray of a second light source (e.g., the second ray 322 of the second light source 320 in Figure 3) is incident on the decorative assembly 200 from the second liquid crystal surface 235, the second light source is observed by an observer 900 located on the motherboard side s1. When the liquid crystal panel 230 switches to the transparent mode, the light transmittance of the liquid crystal panel 230 is greater than or equal to 50%.

[0041] The liquid crystal panel 230 includes two transparent substrates (not shown in the figure), which face the motherboard side s1 and the liquid crystal side s2 respectively. The first motherboard surface 211, the second motherboard surface 215, the first liquid crystal surface 231 and the second liquid crystal surface 235 are parallel to each other.

[0042] Figure 3 illustrates a schematic diagram of a vehicle 300 according to a third embodiment of the present disclosure. Referring to Figures 1A to 1C and Figure 3, the vehicle 300 has an outer side and includes a mainboard structure 110 and a liquid crystal panel 130. Alternatively, the vehicle 300 may include decorative components according to the present disclosure, such as the decorative component 100 of the aforementioned first embodiment, but is not limited thereto. The mainboard structure 110 is transparent and includes a first mainboard surface 111 and a second mainboard surface 115, which are disposed opposite to each other. The first mainboard surface 111 faces and is exposed to the outer side of the vehicle 300, i.e., the mainboard side s1 of the decorative component 100. The liquid crystal panel 130 includes a first liquid crystal surface 131 and a second liquid crystal surface 135, which are disposed opposite to each other. The first liquid crystal surface 131 is connected to at least a portion of the second mainboard surface 115. The liquid crystal panel 130 is flat or bent only along a first direction x1. This improves the manufacturing yield, reliability, and distortion-free performance of the LCD panel 130 bonded to the motherboard structure 110, and enhances the recognizability and aesthetics of the vehicle 300. Specifically, in the third embodiment, the LCD panel 130 is bent only along the first direction x1.

[0043] In detail, when the vehicle 300 is in a specific state, the liquid crystal panel 130 switches to pattern mode. When the liquid crystal panel 130 switches to pattern mode and the first light 811 of the first light source 810 is used to sequentially incident on the main board structure 110 and the liquid crystal panel 130 from the outside, the liquid crystal pattern 137 of the liquid crystal panel 130 can be observed by the observer 900 located on the outside. In this way, the first light source 810 can be ambient light, and the vehicle 300 reflects and displays a specific liquid crystal pattern 137 by switching the liquid crystal panel 130 to pattern / reflection mode.

[0044] The specific state can be before the vehicle 300 is powered off, when the vehicle 300 is stopped, or when the liquid crystal panel 130 does not need to provide a light transmission characteristic. Therefore, by setting the liquid crystal molecule arrangement of the liquid crystal panel 130 in a specific state, the liquid crystal panel 130 can maintain the display of the corresponding liquid crystal pattern 137 in that specific state. For example, since cholesteric liquid crystals only consume power when changing the liquid crystal pattern 137, a pre-set liquid crystal pattern 137 can be written into the cholesteric liquid crystal before the vehicle 300 stops and the main power is interrupted. This allows a specific image (liquid crystal pattern 137) to be retained when the vehicle is stationary and without power, thereby displaying the vehicle's design aesthetics.

[0045] The LCD image 137 may be at least one of a vehicle brand, a vehicle model, a license plate, a driver's identity, an advertisement, and a traffic safety reminder. Therefore, the LCD image 137 can be designed according to the owner's preferences and displayed in specific states of the vehicle 300, which helps improve the recognizability of the vehicle 300.

[0046] The vehicle 300 may further include a temperature sensor 340, which is adjacent to the liquid crystal panel 130 and used to provide a sensed temperature. When the sensed temperature is greater than a transition temperature of the liquid crystal panel 130 and then less than the transition temperature of the liquid crystal panel 130, the liquid crystal panel 130 re-sends a pattern signal corresponding to the liquid crystal pattern 137, wherein the sensed temperature of the liquid crystal panel 130 is greater than the transition temperature and may be in a homeotropic mode. Further, when the sensed temperature is greater than the transition temperature of the liquid crystal panel 130 and then less than a set temperature (e.g., 70 degrees Celsius) of the liquid crystal panel 130, the liquid crystal panel 130 re-sends a pattern signal corresponding to the liquid crystal pattern 137, wherein the set temperature is less than the transition temperature. Therefore, since automotive temperature tests often reach over 100 degrees Celsius, the liquid crystal in the LCD panel 130 also reaches the conversion temperature, making it unable to display the planar mode and the diffused mode, resulting in an abnormal display of the LCD panel 130. By setting a temperature sensor 340 around the LCD panel 130 (e.g., inside the lamp housing), when the temperature is sensed to drop to the normal operating range of the set temperature, the corresponding pattern signal of the LCD pattern 137 is resent to display the LCD pattern 137.

[0047] The mainboard structure 110 can be a vehicle body, a lamp housing, or a window glass. In this way, the vehicle 300 can display specific vehicle information through the reflective properties of the LCD panel 130, or switch to the penetrating properties to comply with driving safety regulations.

[0048] The mainboard structure 110 may be a lamp housing, and the vehicle 300 may further include a second light source 320, which is a lamp source located on the inner side of the mainboard structure 110 and the liquid crystal panel 130, i.e., the liquid crystal side s2 of the decorative component 100. When the vehicle 300 is in motion, the liquid crystal panel 130 switches to a transparent mode. When the liquid crystal panel 130 switches to a transparent mode and the second light ray 322 of the second light source 320 sequentially enters the liquid crystal panel 130 and the mainboard structure 110, the second light source 320 is used to be observed by an observer 900 located on the outside. In this way, the liquid crystal panel 130 can select a transparent mode, i.e., present a transparent state, so that the vehicle lamp light source complies with traffic regulations. In other embodiments of this disclosure (not shown in the figures), the mainboard structure may be a window glass, and can display vehicle-specific information through the reflective characteristics of the liquid crystal panel, or switch to a transparent characteristic to comply with driving safety regulations.

[0049] The ratio of an area of ​​the first liquid crystal surface 131 to an area of ​​the second motherboard surface 115 can be less than 0.5, and the second light ray 322 is not located in a central main light path 324 of the second light source 320. Therefore, when the motherboard structure 110 is the lamp housing of the vehicle 300, it can comply with safety regulations and avoid the loss of headlight brightness that indirectly affects driving safety. For example, before the vehicle 300 starts moving, such as after the main power is started, the specific image (liquid crystal pattern 137) retained by the cholesteric liquid crystal is switched to a transparent mode. At this time, the original optical path of the headlight will not be affected, and the lighting effect will be achieved.

[0050] For other details regarding the decorative component 100 including the motherboard structure 110 and the liquid crystal panel 130 in the third embodiment, please refer to the content of the first embodiment mentioned above, which will not be described in detail here.

[0051] Although the present disclosure has been disclosed above with reference to embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims. [Simplified Explanation of the Diagram]
