[0022] In the first embodiment, the home security device body 110 may be a safe; the display device 120 may be a cholesteric liquid crystal display; the detection device 130 may be an infrared palm print detection device; and the controller 140 may be a microprocessor, a central processing unit (CPU), a mobile device processor, a cloud processor, or other electronic computing processor, but the present disclosure is not limited thereto. Furthermore, in other possible embodiments, the detection device may be an infrared fingerprint detection device, an infrared face detection device, or a voiceprint detection device.

[0023] The home security device body 110 includes a door panel 111, a housing 112, an electronic lock, and a power supply (not shown separately). One end of the door panel 111 is pivotally connected to the housing 112, and the other end of the door panel 111 is selectively disengaged from or locked to the housing 112 via a latch. The electronic lock is disposed on the door panel 111 and is used to control the latch. The power supply is electrically connected to the electronic lock to provide power to the electronic lock. The display device 120 is connected to the door panel 111 and is linked to the door panel 111. When the electronic lock is unlocked, when the user pulls the display device 120 outward, the door panel 111 of the home security device body 110 can be opened simultaneously.

[0024] Referring to Figures 2 and 4A, wherein Figure 4A is a schematic diagram illustrating a display device according to a second embodiment of the present disclosure. The display device 120 includes at least one display module 121 and a light-absorbing module 122, the light-absorbing module 122 being disposed on one side of the display module 121. Furthermore, there may be a plurality of display modules 121, and the display device 120 may further include at least one optical adhesive layer 123 disposed between the display modules 121 for bonding the display modules 121 together.

[0025] The display modules 121 are stacked, and visible light L can pass through the stacked display modules 121 and light absorption modules 122 in sequence to reach the detection device 130.

[0026] In Figure 4A, there are three display modules 121. Each of the three display modules 121 includes a pixel matrix layer (such as pixel matrix layers 1211b, 1211g, and 1211r that can reflect blue, green, and red light respectively in Figure 4A), two transparent conductive layers 1212, and two protective layers 1213. The two transparent conductive layers 1212 of each display module 121 are respectively disposed on two sides of the pixel matrix layers 1211b, 1211g, and 1211r. The two protective layers 1213 of each display module 121 are respectively disposed on the two sides of the two transparent conductive layers 1212 that are away from the pixel matrix layers 1211b, 1211g, and 1211r. In the second embodiment, the transparent conductive layer 1212 may be made of a transparent conductive material such as indium-tin-oxide (ITO) or indium-zinc-oxide (IZO); the protective layer 1213 may be made of a flexible transparent organic material such as glass or polyethylene terephthalate (PET), but the present disclosure is not limited thereto.

[0027] Referring to Figure 4B, which is a schematic diagram illustrating a display device according to a third embodiment of the present disclosure, in the third embodiment, there are also multiple display modules 121. The difference between the display device 120a and the display device 120 of the second embodiment lies in the arrangement and number of the display modules 121. Specifically, the display modules 121 of the display device 120a of the third embodiment are arranged in parallel, and the display modules 121 are a single-layer horizontal structure. It should be noted that the number of display modules 121 can be adjusted according to needs, and the present disclosure is not limited thereto.

[0028] The light absorption module 122 includes a light absorption layer 1221. The light absorption layer 1221 is used to absorb visible light L that passes through the display module 121 and to provide infrared light transmission. The light absorption layer 1221 can be made of an infrared-transmitting material of dye type or coating type, so that a lens 1321 of the detection device 130 can be directly set behind the light absorption module 122 to capture images. The infrared-transmitting material can be an organic dye material such as bromine-substituted dye or nitrososubstituted dye, a black organic dye based on aniline or phenothiazine, or a polymer dye such as polyvinyl chloride dye.

[0029] As further illustrated, referring to Figure 5A, which is a schematic diagram of the light absorption module according to the fourth embodiment of the present disclosure, the light absorption layer 1221 of the light absorption module 122a is made using a coating-type infrared-transmitting material. Specifically, the light absorption layer 1221 is formed by depositing a coating-type infrared-transmitting material onto the side of the protective layer 1213 of the display module 121 away from the transparent conductive layer 1212 using physical vapor deposition (PVD) or chemical vapor deposition (CVD).

[0030] Furthermore, in Figure 5A, the light-absorbing layer 1221 of the light-absorbing module 122a can also be formed by using a black matrix (BM) photoresist from a typical color filter (CF) manufacturing process. Specifically, the BM photoresist can be mixed with a dye-based infrared-transmitting material and then coated onto the side of the protective layer 1213 of the display module 121 away from the transparent conductive layer 1212 to form the light-absorbing layer 1221.

[0031] Referring to Figure 5B, which is a schematic diagram illustrating the light absorption module of the fifth embodiment of this disclosure, the light absorption module 122b may further include a substrate 1222 disposed on one side of the light absorption layer 1221 and attached to a lens 1321 of the detection device 130. The light absorption layer 1221 of the light absorption module 122b is made of a dye-based infrared-permeable material. The light absorption layer 1221 is formed by first mixing the dye-based infrared-permeable material with an optical adhesive and then coating it onto the substrate 1222. In the fifth embodiment, the substrate 1222 may be made of PET, polymethyl methacrylate (PMMA), polycarbonate (PC), or polyvinyl chloride (PVC), but this disclosure is not limited thereto.

[0032] Referring to Figure 5C, which is a schematic diagram illustrating the light-absorbing module of the sixth embodiment of the present disclosure, the light-absorbing module 122b may further include an adhesive layer 1223 disposed on one side of the light-absorbing layer 1221, adhering to the protective layer 1213 of the display module 121. The light-absorbing layer 1221 of the light-absorbing module 122b is also made of a dye-based infrared-transmitting material. The light-absorbing layer 1221 is formed by first mixing the dye-based infrared-transmitting material with a substrate such as plastic or ABS resin. Then, the light-absorbing layer 1221 can be bonded to the display module 121 by the adhesive layer 1223. It should be noted that the light-absorbing layer 1221 can increase the infrared transmission efficiency while maintaining the inherent properties of plastic by adjusting the different material ratios during the processing.

[0033] Referring to Figure 3, the detection device 130 includes an infrared light source module 131 and a camera module 132. The infrared light source module 131 is used to illuminate the user. The camera module 132 is used to capture an image of the area illuminated by the infrared light source module 131. In the first embodiment, the camera module 132 may be a camera with an infrared band, and the camera module 132 is preferably a 3D Time of Flight (ToF) camera.

[0034] In addition, in the first embodiment, the infrared light source module 131 illuminates the user's palm, and the camera module 132 generates an image by photographing the user's palm, but the content of this disclosure is not limited thereto.

[0035] To further explain, human veins have light-absorbing properties. Deoxyhemoglobin in hemoglobin strongly absorbs infrared light, causing the veins to appear as black shadows, thus forming a vein pattern for the camera module 132 to capture.

[0036] The controller 140 includes a preprocessing unit 141, an identification unit 142, a comparison unit 143, and a security device control unit 144, all connected by signals. The preprocessing unit 141 acquires images from the camera module 132 and performs preprocessing on the images to remove noise and enhance vein features. The identification unit 142 performs feature analysis on the preprocessed images to generate feature information. The comparison unit 143 compares the feature information with a pre-stored verification feature to generate a comparison score. The security device control unit 144 controls the electronic lock of the home security device body 110 based on the comparison score. Specifically, when the comparison score is greater than a threshold value, the security device control unit 144 unlocks the electronic lock of the home security device body 110.

[0037] To further explain, the user can place their palm in front of the detection device 130 so that the detection device 130 can capture the image, and the controller 140 can perform preprocessing, feature analysis, and feature comparison on the image. When the comparison score is greater than the threshold value, it indicates that the user's identity verification is successful. At this time, the controller 140 will unlock the home security device body 110. The user can pull open the display device 120 in front of the home security device body 110 (as shown in Figure 1) to simultaneously open the door panel 111 of the home security device body 110. In this way, by identifying the user's identity through palm vein recognition by the detection device 130 and the controller 140, security and anti-counterfeiting capabilities can be further improved.

[0038] The controller 140 may further include a display control unit 145, which controls the display device 120 to display image data. After the display device 120 displays image data through the display control unit 145, the home security device 100 with a display can be used as a digital picture frame or digital photo frame for interior decoration. In this way, in addition to hiding the home security device body 110 behind paintings or photos to improve security and privacy, users can connect to the display control unit 145 through electronic devices such as mobile phones to upload or change the image data to be displayed at any time, thereby improving the convenience of use.

[0039] Furthermore, the display device 120 uses a cholesteric liquid crystal display, which can maintain the display of image data for a long time without consuming power. In addition, it allows infrared light to penetrate, so that the infrared light source module 131 and the camera module 132 behind the display device 120 can respectively illuminate the user and capture the user's image, thereby automatically controlling the unlocking of the home security device body 110.

[0040] Referring to Figures 6, 7, and 8, Figure 6 is a perspective view of a home security device with a display according to the seventh embodiment of the present disclosure; Figure 7 is a cross-sectional view of the home security device with a display according to the seventh embodiment of Figure 6; and Figure 8 is a block diagram of the home security device with a display according to the seventh embodiment of the present disclosure. The home security device 200 with a display includes a home security device body 210, a display device 220, a detection device 230, and a controller 240. The display device 220 is disposed on the top of the home security device body 210, and the detection device 230 is disposed on one side of the display device 220. The display device 220 and the detection device 230 can be integrally combined with the home security device body 210. The controller 240 is signal-connected to the home security device body 210, the display device 220, and the detection device 230.

[0041] In the seventh embodiment, the display device 220, the detection device 230 and the controller 240 are the same as the display device 120, the detection device 130 and the controller 140 in the first embodiment, respectively, and will not be described again here.

[0042] The difference between the seventh embodiment and the third embodiment is that the home security device body 210 is a smart lock. Specifically, the controller 240 controls the unlocking of the home security device body 210 based on the image from the detection device 230. After the display device 220 displays the image data, it can hide the detection device 230 behind it so that its location cannot be confirmed by outsiders. Compared with existing smart locks, it is more difficult to crack and has greater privacy and security. Furthermore, in other possible embodiments, the display device can also completely cover the home security device body, which has the effect of hiding the smart lock and is more suitable for users who value high privacy requirements.

[0043] Referring to Figures 7, 8 and 9, wherein Figure 9 is a perspective view illustrating a home security device with a display according to the eighth embodiment of the present disclosure. The difference between the home security device 200a with a display and the home security device 200 with a display according to the seventh embodiment lies in the arrangement of the display device 220 and the detection device 230.

[0044] In detail, the display device 220 of the eighth embodiment can be installed at the door of a home as a smart address, displaying the user's address as image data. A detection device 230 is located behind the display device 220, and the controller 240 controls the home security device 210 to unlock based on the image detected by the detection device 230. Furthermore, after the home security device 210 is unlocked, the controller 240 can control the display device 220 to switch the image data from the address to display words such as "Welcome" or "Welcome Home".

[0045] In this way, by concealing the location of the detection device 230 in the smart doorplate, non-homeowner visitors cannot confirm from the appearance of the smart doorplate that it has the function of unlocking the door lock, thereby further achieving the purpose of home protection.

[0046] As can be seen from the above embodiments, the home security device with a display disclosed herein has the following advantages: First, after the display device displays image data through the display control unit, the home security device body can be hidden behind paintings, photos or doorplates, and the image data to be displayed can be uploaded or changed at any time, thereby improving the convenience of use; Second, because the display device uses a cholesteric liquid crystal display that allows infrared light to penetrate, the infrared light source module and the camera module behind it can respectively illuminate the user and capture the user's image, thereby automatically controlling the unlocking of the home security device body; Third, by using a detection device and controller to identify the user's identity through vein recognition, the security and anti-counterfeiting capabilities can be further improved.

[0047] 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 disclosed content shall be determined by the appended claims. [Simplified Explanation of the Diagram]
