[0022] The following is an explanation of the implementation methods of the "hidden display device and its manufacturing method" disclosed in the present invention through specific specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention. In addition, it should be stated in advance that the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. The following implementation methods will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention. In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0023] See also Figures 1 to 8 As shown, the present invention provides a method for manufacturing a hidden display device P. The method for manufacturing the hidden display device P may at least include: first, Figure 1 and Figure 2 As shown, an appearance decoration structure 1 is provided, and the appearance decoration structure 1 includes an appearance decoration shell 11, and the appearance decoration shell 11 has a plurality of micron-level through openings 110 arranged in a predetermined arrangement shape (step S100); then, Figure 1 and Figure 2 As shown, a light emitting diode module 2 is provided, and the light emitting diode module 2 has a plurality of micro light emitting diode units 22 arranged in a predetermined arrangement shape (step S102); then, Figure 1 and Figure 3 As shown, the light emitting diode module 2 is installed inside the appearance decoration structure 1 so that the light emitting diode module 2 is covered by the appearance decoration structure 1 (step S104); next, Figure 1 and Figure 3As shown, an alignment step is performed so that the plurality of micro-LED units 22 correspond to the plurality of micron-scale through openings 110 respectively (step S106). It is worth noting that the maximum diameter D (or maximum width) of each micron-scale through opening 110 can be approximately between 5 μm and 200 μm (or any positive integer less than 5 μm, or any positive integer greater than 200 μm, or any positive integer between 1 μm and 1000 μm), and the minimum spacing G between any two adjacent micron-scale through openings 110 can be approximately between 50 μm and 100 μm (or any positive integer less than 50 μm, or any positive integer greater than 100 μm, or any positive integer between 50 μm and 100 μm).

[0024] For example, in step S100 of providing the appearance decoration structure 1, a predetermined arrangement shape in which multiple micron-scale through openings 110 need to be arranged can be pre-planned, and then multiple micron-scale through openings 110 can be formed on the appearance decoration shell 11 by laser processing or any other processing method according to the pre-planned predetermined arrangement shape. In addition, in step S106 of performing the alignment step, multiple micro-LED units 22 can be optically aligned to accurately correspond to the multiple micron-scale through openings 110, so that the projection light sources generated by the multiple micro-LED units 22 can pass through the multiple micron-scale through openings 110 respectively (for example, an image capture system can be used to determine whether the multiple projection light sources generated by the multiple micro-LED units 22 have accurately passed through the multiple micron-scale through openings 110). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0025] In this way, cooperate Figure 5 or Figure 7 As shown, when the multiple micro-LED units 22 are completely turned off through the control of a signal control module 3, since the LED module 2 has been covered by the exterior decoration structure 1 and is limited by the visual ability (or recognition ability) of the human eye, the user (or driver) cannot recognize (or cannot perceive) the multiple micron-level through openings 110 of the exterior decoration shell 11 with their naked eyes, so that the exterior decoration shell 11 can be presented to the user in a hole-free manner (that is, when the multiple micro-LED units 22 are completely turned off, the user can only observe the exterior decoration shell 11 without any holes with the naked eye, thereby achieving the purpose of hiding the LED module 2).

[0026] Furthermore, if Figure 6As shown, when a plurality of micro-LED units 22 are controlled by a signal control module 3 to provide a predetermined image M (such as any dynamic image or static image), the predetermined image M provided by the plurality of micro-LED units 22 can be presented on the exterior decoration shell 11 through a plurality of micron-level through openings 110 (that is, when the plurality of micro-LED units 22 cooperate with each other to provide a predetermined image M, through the plurality of micron-level through openings 110 respectively corresponding to the plurality of micro-LED units 22, the user can view the predetermined image M presented on the exterior decoration shell 11 with the naked eye). It is worth noting that the predetermined image M is generated by the plurality of micro-LED units 22 being turned on (lit up) in sequence within a predetermined period (or within a predetermined time), that is, the plurality of micro-LED units 22 used to provide the predetermined image M will not be turned on at the same time point, thereby saving power and improving the heat dissipation effect.

[0027] Furthermore, with Figure 6 or Figure 8 As shown, when the plurality of micro-LED units 22 are controlled by the signal control module 3 to provide a predetermined light source L (e.g., a yellow light source, a red light source, a white light source, or a light source of any other color), the predetermined light source L provided by the plurality of micro-LED units 22 can be presented on the exterior decoration housing 11 through the plurality of micro-level through openings 110 (that is, when the plurality of micro-LED units 22 cooperate with each other to provide a predetermined light source L, through the plurality of micro-level through openings 110 respectively corresponding to the plurality of micro-LED units 22, the user can see the predetermined light source L presented on the exterior decoration housing 11 only by naked eyes). It is worth noting that the predetermined light source L is generated by the plurality of micro-LED units 22 being turned on (lit up) in sequence within a predetermined cycle (or within a predetermined time), that is, the plurality of micro-LED units 22 used to provide the predetermined light source L will not be turned on at the same time point, thereby saving power and improving the heat dissipation effect.

[0028] [First embodiment]

[0029] See also Figures 3 to 8As shown, the first embodiment of the present invention provides a hidden display device P, and the hidden display device P includes an appearance decoration structure 1, a light emitting diode module 2 (or an image display device, or a light source providing device) and a signal control module 3. More specifically, the appearance decoration structure 1 includes an appearance decoration shell 11 and a transparent protective layer 12 disposed on the appearance decoration shell 11, the light emitting diode module 2 can be covered by the appearance decoration structure 1, and the signal control module 3 is electrically connected to the light emitting diode module 2. It is worth noting that, according to different requirements, the transparent protective layer 12 provided in the first embodiment of the present invention can also be omitted and not used.

[0030] For example, if Figure 3 As shown, the exterior decoration shell 11 can be made of any opaque material, such as any opaque material used indoors, or any opaque material used in cars. In addition, the exterior decoration shell 11 has a plurality of micron-sized through openings 110 arranged in a predetermined arrangement shape, and the plurality of micron-sized through openings 110 can be covered by a transparent protective layer 12, or the transparent protective layer 12 can be omitted so that the plurality of micron-sized through openings 110 can be exposed. In addition, the maximum diameter D of each micron-sized through opening 110 can be approximately between 5 μm and 200 μm, and the minimum spacing G between any two adjacent micron-sized through openings 110 can be approximately between 50 μm and 100 μm. Furthermore, each micron-scale through-opening 110 may be a laser perforation formed by laser processing (or each micron-scale through-opening 110 may also be a through-hole formed by any other type of drilling method), the maximum diameter D of each micron-scale through-opening 110 may be between any two positive integers greater than 5 μm and less than 200 μm (or any positive integer less than 5 μm, or any positive integer greater than 200 μm, or any positive integer between 1 μm and 1000 μm), and the minimum spacing G between any two adjacent micron-scale through-openings 110 may be between any two positive integers greater than 50 μm and less than 100 μm (or any positive integer less than 50 μm, or any positive integer greater than 100 μm). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0031] For example, if Figure 3As shown, the transparent protective layer 12 can be made of any transparent material, for example, any transparent material that can be used indoors, or any transparent material that can be used in cars). In addition, the transparent protective layer 12 is arranged in an internal area within the multiple micron-sized through openings 110 located in the exterior decoration shell 11, so as to close the multiple micron-sized through openings 110. Furthermore, when the transparent protective layer 12 is arranged in the internal area within the multiple micron-sized through openings 110 located in the exterior decoration shell 11, the transparent protective layer 12 has multiple transparent filling bodies 121 separated from each other, so as to be respectively filled in the multiple micron-sized through openings 110 and completely expose the outer surface of the exterior decoration shell 11 (that is, the outer surface of the exterior decoration shell 11 will not be covered by the multiple transparent filling bodies 121). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0032] For example, with Figure 3 and Figure 4 As shown, the LED module 2 has a flexible substrate 21 (or a non-flexible substrate) and a plurality of micro-LED units 22. The flexible substrate 21 can be configured (e.g., bent) to conform to the appearance of the appearance decoration housing 11, and the plurality of micro-LED units 22 are disposed on the flexible substrate 21 and electrically connected to the flexible substrate 21. In addition, the plurality of micro-LED units 22 can be configured to be arranged in a predetermined arrangement shape and correspond to a plurality of micron-level through openings 110, respectively, and each micro-LED unit 22 can be turned off or on by the control of the signal control module 3. In addition, the top of each micro-LED unit 22 has a light emitting surface 2200, and the light emitting surface 2200 of each micro-LED unit 22 is disposed outside the corresponding micron-level through opening 110, so that the plurality of micro-LED units 22 can be in contact with or not in contact with the appearance decoration housing 11 or the transparent protective layer 12 of the appearance decoration structure 1. It is worth noting that the signal control module 3 may include multiple microcontrollers (such as CMOS), and the multiple microcontrollers may be disposed on the flexible substrate 21 to respectively control the multiple micro LED units 22. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0033] For example, with Figure 3 and Figure 4 As shown, each micro-LED unit 22 includes a micro-LED chip 22C (eg, Figure 3 as shown) or multiple micro light emitting diode chips (such as Figure 4As shown). Further, when each micro-LED unit 22 includes a micro-LED chip 22C, the micro-LED chip 22C can generate a specific color light source according to demand (for example, using a red micro-LED chip, a green micro-LED chip or a blue micro-LED chip 22B), or the micro-LED chip 22C can also be matched with phosphor to generate a specific color light source (for example, a blue micro-LED chip can be matched with yellow phosphor to generate a white light source). When each micro-LED unit 22 includes a plurality of micro-LED chips, the plurality of micro-LED chips of each micro-LED unit 22 include a red micro-LED chip 22R for providing a red light source, a green micro-LED chip 22G for providing a green light source, and a blue micro-LED chip 22B for providing a blue light source, and the red micro-LED chip 22R, the green micro-LED chip 22G and the blue micro-LED chip 22B can cooperate with each other to form an image pixel of a predetermined image M. In addition, the LED module 2 further includes a plurality of light-proof structures 23 (i.e., a plurality of light-shielding structures made of any light-proof material), and each light-proof structure 23 can be disposed between two adjacent micro-LED units 22 to prevent any two adjacent micro-LED units 22 from being affected by crosstalk. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0034] For example, with Figures 5 to 8 As shown, the appearance decoration structure 1 can be applied indoors or outdoors, and the appearance decoration structure 1 can be applied to the interior or exterior of a car C. Furthermore, when the appearance decoration structure 1 is applied to a car C, the appearance decoration housing 11 can be configured as an external housing (i.e., the exterior sheet metal of the car) or an interior decoration (i.e., the interior decoration of the car) of the car C. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0035] For example, with Figure 5 and Figure 6As shown, in one of the feasible embodiments, when the exterior decoration shell 11 is configured as the interior decoration of the car C, the predetermined image M provided by the plurality of micro-LED units 22 can be applied to an A-pillar structure S1 located inside the car C, so as to present the external image located behind the A-pillar structure S1 on the surface of the A-pillar structure S1. Thus, when the LED module 2 is turned on, the driver can view the external image located behind the A-pillar structure S1 (that is, the driver's field of vision blocked by the A-pillar structure S1) through the predetermined image M presented on the surface of the A-pillar structure S1, so that the driver can see through the A-pillar structure S1, which helps to solve the visual blind spot problem caused by the A-pillar structure S1 to the driver. However, the above example is only one of the feasible embodiments and is not intended to limit the present invention.

[0036] For example, with Figure 5 and Figure 6 As shown, in one of the feasible embodiments, when the exterior decoration housing 11 is configured as the interior decoration of the car C, the predetermined image M provided by the plurality of micro-LED units 22 can be applied to the interior of the car C to serve as a vehicle dashboard S2 ( Figure 5 and Figure 6 Two vehicle dashboards S2 are used as examples for explanation), thereby providing the user with relevant dashboard information (that is, the car C can omit the use of a conventional exposed vehicle dashboard). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0037] For example, with Figure 5 and Figure 6 As shown, in one of the feasible embodiments, when the exterior decoration housing 11 is configured as the interior decoration of the car C, the predetermined image M provided by the plurality of micro-LED units 22 can be applied to the interior of the car C to serve as a car display S3 for providing an information image, thereby providing the user with relevant audio and video information (that is, the car C can omit the use of a conventional exposed car display). It is worth noting that the car display S3 can also be set at any position near the rear seat of the car to facilitate the rear seat passengers to watch. However, the above example is only one of the feasible embodiments and is not intended to limit the present invention.

[0038] For example, with Figure 5 and Figure 6As shown, in one of the feasible embodiments, when the exterior decoration housing 11 is configured as the interior decoration of the car C, the predetermined light source L provided by the plurality of micro-LED units 22 can be applied to the interior of the car C to serve as a vehicle lighting lamp S4 for providing a lighting source (that is, the car C can omit the use of a conventional exposed vehicle lighting lamp). However, the above example is only one of the feasible embodiments and is not intended to limit the present invention.

[0039] It is worth noting that, for example, in one feasible embodiment, when the exterior decoration housing 11 is configured as an external housing of a car C, the predetermined image M provided by the plurality of micro-LED units 22 can be applied to the exterior of the car C to serve as an advertising billboard for providing an advertising image (for example, it can be an advertising billboard installed on the door or body of the car C). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0040] For example, with Figure 7 and Figure 8 As shown, in one of the feasible embodiments, when the exterior decoration housing 11 is configured as an external housing of a car C, the predetermined light source L provided by the plurality of micro-LED units 22 can be applied to the exterior of the car C to serve as a rear vehicle lamp S5 (for example, a reversing lamp, a brake lamp, a warning lamp, or a direction lamp) for providing a warning light source. Figure 7 and Figure 8 Four rear lights S5 are used as an example for explanation). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0041] In this way, cooperate Figure 5 or Figure 7 As shown, when the multiple micro-LED units 22 are completely turned off by a signal control module 3, since the LED module 2 has been covered by the exterior decoration structure 1 and is limited by the visual ability (or recognition ability) of the human eye, the user (or driver) cannot recognize (or cannot perceive) the multiple micron-level through openings 110 of the exterior decoration shell 11 with their naked eyes, so that the exterior decoration shell 11 can be presented to the user in a hole-free manner (that is, when the multiple micro-LED units 22 are completely turned off, the user can only observe the exterior decoration shell 11 without any holes with the naked eye). Furthermore, as Figure 6As shown, when a plurality of micro-LED units 22 are controlled by a signal control module 3 to provide a predetermined image M (such as any dynamic image or static image), the predetermined image M provided by the plurality of micro-LED units 22 can be presented on the exterior decoration shell 11 through a plurality of micron-level through openings 110 (that is, when a plurality of micro-LED units 22 cooperate with each other to provide a predetermined image M, through a plurality of micron-level through openings 110 respectively corresponding to the plurality of micro-LED units 22, the user can view the predetermined image M presented on the exterior decoration shell 11 with the naked eye). Figure 6 or Figure 8 As shown, when a plurality of micro-LED units 22 are controlled by the signal control module 3 to provide a predetermined light source L (for example, a yellow light source, a red light source, a white light source or a light source of any other color), the predetermined light source L provided by the plurality of micro-LED units 22 can be presented on the exterior decoration shell 11 through a plurality of micron-sized through openings 110 (that is, when a plurality of micro-LED units 22 cooperate with each other to provide a predetermined light source L, through a plurality of micron-sized through openings 110 respectively corresponding to the plurality of micro-LED units 22, the user can view the predetermined light source L presented on the exterior decoration shell 11 with the naked eye).

[0042] It is worth noting that, for example, Figure 4 As shown, the hidden display device P further includes a light sensing module 24, which includes a plurality of light sensing components 240 (such as light sensors or fingerprint sensors) electrically connected to the signal control module 3, and the plurality of light sensing components 240 can correspond to all of the plurality of micro-LED units 22 or correspond to a portion of the plurality of micro-LED units 22 (that is, a portion of the light sensing components 240 corresponds to a portion of the micro-LED units 22) for identifying the user's fingerprint image (that is, the A-pillar structure S1, the vehicle dashboard S2, the vehicle display S3, the vehicle lighting S4 and the rear vehicle lamp S5 can be equipped with a fingerprint recognition function). However, the above example is only one feasible embodiment and is not intended to limit the present invention.
