When in use, the face recognition module 3 and the fingerprint recognition module 4 can control the color to be transparent or opaque. The working principle of the dimming glass 2: it is mainly based on the electrically controlled arrangement change of liquid crystal molecules. A layer of liquid crystal dimming film is sandwiched in the middle of the dimming glass 2. This film is composed of liquid crystal and conductive material. In the power-off state, the liquid crystal molecules are irregularly scattered, causing light to scatter, and the glass appears opaque milky white. When powered on, the liquid crystal molecules are neatly arranged under the action of the electric field, and light can penetrate freely, and the glass becomes transparent. The specific structure of the dimming glass 2 and its use are existing well-known technologies and will not be described in detail here.

[0028] In this embodiment, the utility model adopts dimming glass 2. When in use, the face recognition module 3 and the fingerprint recognition module 4 can control the color adjustment to be transparent or opaque. When in use, the user uses the face recognition module 3 and the fingerprint recognition module 4 to identify the information. After the information passes, the dimming glass 2 becomes transparent to display the information. When the user leaves the recognition area of ​​the face recognition module 3 after use, the dimming glass 2 can be adjusted to an opaque state to ensure the security of the information. It is simple and convenient to use and is better.

[0029] Further, the upper and lower ends of the right front end of the fingerprint identification module 4 are fixedly connected with a guide shaft 5, the left side of the guide shaft 5 is a rectangular structure, the right side of the guide shaft 5 is a semicircular structure, the front end of the guide shaft 5 is provided with a screw hole 16, the front end of the guide shaft 5 is provided with a limit bar 6, the front end of the limit bar 6 is provided with a countersunk hole 14, the inside of the countersunk hole 14 is provided with a fixing screw 15, the rear end of the fixing screw 15 is screwed and connected with the screw hole 16, and the guide shaft 5 and the limit bar 6 are both PVC components;

[0030] The front end of the fingerprint recognition module 4 is provided with a protective cover 7, which is a PVC component, and the rear end of the protective cover 7 is bonded with a rag 8, which is a flannel, and the middle position of the front right side of the protective cover 7 is integrally connected with a push-pull block 11;

[0031] The front right side of the protective cover 7 is bonded with an indication arrow sticker 12, which is a PVC sticker. The front left side of the protective cover 7 is bonded with a fingerprint identification label 13, which is a PVC sticker.

[0032] Guide grooves 9 are provided at both the upper and lower ends of the fingerprint recognition module 4. The left side of the guide groove 9 is a rectangular structure, and the right side of the guide groove 9 is a semicircular structure. The guide shaft 5 is slidably connected to the guide groove 9, and the length of the limit strip 6 is greater than the width of the guide groove 9. A spring 10 is provided inside the guide groove 9, and the left end of the spring 10 is fixedly connected to the left side of the guide groove 9, and the right end of the spring 10 is fixedly connected to the left side of the guide shaft 5.

[0033] Among them, the guide shaft 5, the limit bar 6 and the guide groove 9 are used to guide and limit the protective cover 7 during the sliding process, so that the protective cover 7 can slide stably, and the spring 10 is used to allow the protective cover 7 to rebound and reset by itself, which is labor-saving and convenient. The limit bar 6 and the guide shaft 5 are connected by screws, and the wiping cloth 8 is bonded and connected, so that the limit bar 6 can be removed from the guide shaft 5, and the protective cover 7 can be further removed, and the wiping cloth 8 can be replaced. The fingerprint recognition label 13 is used to prompt that the place covered by the protective cover 7 on the display body 1 is the place for fingerprint recognition, and the fingerprint recognition label 13 is printed with the words "fingerprint recognition place", which is not specifically shown in the figure, and the indicator arrow label 12 is used to prompt that pushing the protective cover 7 is to push to the right, and the push-pull block 11 is used to facilitate the pushing of the protective cover 7.

[0034] In this embodiment, when the utility model is in use, the recognition area of ​​the fingerprint recognition module 4 after use can be wiped by the protective cover 7 with a wiping cloth 8 that can be slid open and closed outside the fingerprint recognition module 4, so as to remove the finger stains remaining in the recognition area of ​​the fingerprint recognition module 4, so as to ensure the daily fingerprint recognition use of the fingerprint recognition module 4 and make it better.

[0035] The use process and working principle of the utility model are as follows: after the dimming glass 2 is fixedly installed in the display body 1, the face recognition module 3 and the fingerprint recognition module 4 are connected. When the user uses the display body 1, the face recognition module 3 and the fingerprint recognition module 4 can perform information recognition. After the information is passed, the face recognition module 3 and the fingerprint recognition module 4 control the dimming glass 2 to adjust the color to be transparent, so as to display the information in the display body 1. After use, when the user leaves the recognition area of ​​the face recognition module 3, the face recognition module 3 controls the dimming glass 2 to adjust the color to be opaque. To ensure the security of information in the display body 1, the working principle of the dimming glass 2 is mainly based on the electrically controlled arrangement change of liquid crystal molecules. A layer of liquid crystal dimming film is sandwiched in the middle of the dimming glass 2. This film is composed of liquid crystal and conductive materials. In the power-off state, the liquid crystal molecules are irregularly scattered, causing light to scatter, and the glass appears opaque milky white. When powered on, the liquid crystal molecules are neatly arranged under the action of the electric field, and light can penetrate freely, and the glass becomes transparent. The specific structure and use of the dimming glass 2 are existing well-known technologies and will not be described in detail here.

[0036] When the fingerprint recognition module 4 is in use, the protective cover 7 can be pushed to the right by the push-pull block 11. During this process, the protective cover 7 slides to the right relative to the guide shaft 5 on the fingerprint recognition module 4 through the guide groove 9, and drives the spring 10 to be compressed, and is limited by the limit bar 6 to prevent the protective cover 7 from falling off the fingerprint recognition module 4. After the protective cover 7 is pushed to the right side of the fingerprint recognition module 4, the recognition area of ​​the fingerprint recognition module 4 is exposed to perform fingerprint recognition of the fingerprint recognition module 4. After the fingerprint recognition module 4 is used, the protective cover 7 can automatically move to the right under the rebound force of the spring 10, and in the process of moving to the right, the finger stains remaining on the recognition area of ​​the fingerprint recognition module 4 are wiped and cleaned by the wiping cloth 8 on the protective cover 7, so that the fingerprint recognition module 4 can be used for daily fingerprint recognition, which is better.
