The main control chip 6 can regulate the backlight module 2 according to the processing signal.
[0063] Furthermore, the first sub-control chip 5 can simplify the calculation of the main control chip 6 and improve the processing efficiency of the main control chip 6 .
[0064] Specifically, Figure 6The flowchart of the method for adjusting the working state of the hidden infrared display screen in the embodiment of the present invention is shown. The main control chip 6 adjusts the working state of the display screen based on the control instruction received by the infrared receiving device 3, including:
[0065] S111: In the shutdown state or the display state, the main control chip 6 starts the infrared sensing element 71 and the pressure sensing element 81 based on the standby instruction received by the infrared receiving device 3, and the display screen enters the standby state.
[0066] Specifically, in the shutdown state, the main control chip 6 is in a dormant state, and the backlight module 2, the first infrared recognition matrix, the second infrared recognition matrix and other components are in an open circuit state, that is, in a non-operating state. The infrared receiving device 3 is connected to the first sub-control chip 5, and the first sub-control chip 5 is in a working state with the power supply support of the internal power supply 4 of the display screen, that is, the infrared receiving device 3 can operate normally in the shutdown state.
[0067] Specifically, the user can turn on the device through a remote control or a mobile phone operation terminal, and the remote control or mobile phone operation terminal generates a standby instruction based on the user's operation and transmits the signal by emitting infrared light. After the infrared receiving device 3 receives the infrared light emitted by the remote control or the mobile phone operation terminal, it sends the acquired infrared signal to the first sub-control chip 5, and the first sub-control chip 5 processes the infrared signal and generates a processed signal to send to the main control chip 6.
[0068] Furthermore, after receiving the infrared signal, the first sub-control chip 5 generates a wake-up instruction to wake up the main control chip 6, so that the main control chip 6 can respond quickly.
[0069] Specifically, the main control chip 6 connects the circuits where the infrared sensing element 71 and the pressure sensing element 81 are located based on the processing signal, so that the infrared sensing element 71 and the pressure sensing element 81 are in a working state.
[0070] Specifically, in the display state, the main control chip 6 can cut off the circuit where the backlight module 2 is located based on the standby instruction, and connect the circuit where the infrared sensing element 71 and the pressure sensing element 81 are located, so that the display screen enters the standby state.

[0073] Or the main control chip 6 turns off the backlight module 2 based on the standby instruction received by the infrared receiving device 3, and starts the infrared sensing element 71 and the pressure sensing element 81, and the display screen enters the standby state.
[0074] S12 : In the standby state, the main control chip 6 stimulates the first infrared transceiver matrix 7 based on the recognition content of the infrared sensing element 71 .
[0075] Specifically, in the standby state, the infrared sensing element 71 emits infrared sensing light outwardly. When the infrared sensing light is blocked, the infrared sensing element 71 generates sensing information and feeds it back to the main control chip 6 .
[0076] Specifically, when the display screen is in standby mode and the user needs to wake up the screen, the user can place the face close to the first infrared transceiver matrix 7 for face recognition. The infrared sensing element 71 emits infrared sensing light to the outside. When the infrared sensing light is blocked by the user, the infrared sensing element 71 generates sensing information based on the received reflected infrared light and feeds the sensing information back to the main control chip 6.
[0077] Specifically, the main control chip 6 turns off the infrared sensing element 71 based on the sensing information, and stimulates the first infrared transceiver matrix 7 to emit infrared recognition light, and the first infrared transceiver matrix 7 enters the recognition state. The first infrared transceiver matrix 7 emits infrared recognition light to the outside, and the infrared recognition light penetrates the backlight module 2 and is emitted outside the display screen, thereby performing face recognition on the user.
[0078] Furthermore, the infrared sensing element 71 is provided with a sensing distance, and the user needs to be within the sensing distance to trigger face recognition, thereby reducing the risk of false triggering of the first infrared recognition matrix.
[0079] Furthermore, the main control chip 6 is set with a first preset time, and the first preset time is used to limit the response time of the first infrared transceiver matrix 7. After the first infrared transceiver matrix 7 enters the recognition state, the main control chip 6 performs timing internally, and stops timing after the main control chip 6 receives the face recognition information fed back by the first infrared transceiver matrix 7. If the timing data of the main control chip 6 exceeds the first preset time, the main control chip 6 turns off the first infrared transceiver matrix 7 and turns on the infrared sensing element 71, and the display screen enters the standby state.
[0080] Furthermore, the main control chip 6 limits the recognition response time of the first infrared transceiver matrix 7 by setting a first preset time, so as to avoid energy waste caused by the first infrared transceiver matrix 7 being accidentally touched.

[0082] Specifically, the first infrared transceiver matrix 7 generates first identification information based on the identification content of the infrared identification light and feeds back to the main control chip 6;
[0083] The main control chip 6 matches and analyzes the first identification information with the preset first comparison information. If the analysis result matches, the main control chip 6 turns off the first infrared transceiver matrix 7 and the pressure sensing element 81, and drives the backlight module 2 to put the display screen into a display state.
[0084] Specifically, the main control chip 6 is provided with first comparison information, and the first comparison information is facial information reserved for the user. The main control chip 6 obtains the first identification information according to the first infrared transceiver matrix 7, and compares the first identification information with the first comparison information. If the comparison result matches, the main control chip 6 controls the display screen to enter the display state.
[0085] Furthermore, when entering the display state, the main control chip 6 turns off the first infrared transceiver matrix 7 and the pressure sensing element 81 , thereby preventing other elements from being falsely triggered and affecting the display effect of the backlight module 2 .
[0086] Specifically, the main control chip 6 compares multiple features of the user's face according to the first identification information obtained by the first infrared transceiver matrix 7, including facial features such as eyes, nose, mouth, eyebrow distance, forehead width, ears, etc. When the facial feature matching rate between the first identification information and the first comparison information reaches 95%, the main control chip 6 controls the display screen to enter the display state, thereby improving the safety of the display screen.
[0087] S14: In the standby state, the main control chip 6 excites the second infrared transceiver matrix 8 based on the recognition content of the pressure sensing element 81;
[0088] Specifically, when the pressure sensing element 81 is triggered, the pressure sensing element 81 generates pressure sensing information and feeds it back to the main control chip 6;
[0089] The main control chip 6 turns off the pressure sensing element 81 based on the pressure sensing information, and stimulates the second infrared transceiver matrix 8 to emit infrared recognition light, and the second infrared transceiver matrix 8 enters the recognition state.
[0090] Specifically, the triggering principle of the recognition state of the second infrared transceiver matrix 8 is the same as the triggering principle of the recognition state of the first infrared transceiver matrix 7. For details, please refer to the triggering principle of the recognition state of the first infrared transceiver matrix 7, which will not be repeated here.
[0091] S15: the main control chip 6 drives the backlight module 2 based on the identification content of the second infrared transceiver matrix 8, and the display screen enters a display state.
[0092] Specifically, the second infrared transceiver matrix 8 generates second identification information based on the identification content of the infrared identification light and feeds back the second identification information to the main control chip 6 .
[0093] The main control chip 6 matches and analyzes the second identification information with the preset second comparison information. If the analysis result matches, the main control chip 6 turns off the second infrared transceiver matrix 8 and the infrared sensing element 71, and drives the backlight module 2 to put the display screen into a display state.
[0094] Specifically, the second comparison information is fingerprint information preset by the user, and the second comparison information includes several fingerprint fragments of the user's fingerprint. The main control chip 6 receives the second identification information obtained by the second infrared transceiver matrix 8, and the second identification information includes several fragment samples of the user's finger fingerprint. The main control chip 6 compares several of the fragment samples with several fingerprint fragments in the second comparison information. When the comparison matching degree reaches 98%, the main control chip 6 controls the display screen to enter the display state.
[0095] Furthermore, a second preset time is set in the main control chip 6, and the second preset time is used to limit the response time of the second infrared transceiver matrix 8. Its function is the same as the first preset time, and it will not be repeated here.
[0096] Specifically, in the present embodiment, the working states of the first infrared transceiver matrix 7 and the second infrared transceiver matrix 8 are separated from the working state of the backlight module 2, so as to avoid the first infrared transceiver matrix 7 and the second infrared transceiver matrix 8 affecting the display effect of the backlight module 2, and at the same time avoid the display screen affecting the recognition accuracy of the first infrared transceiver matrix 7 and the second infrared transceiver matrix 8 when in the display state.

The hidden display screen hides the infrared transceiver component behind the backlight module 2, and identifies and wakes up the standby state of the display screen by setting an infrared transceiver matrix, thereby separating the working states of the display screen and the infrared transceiver matrix to avoid mutual influence, reduce energy waste, and ensure a good display effect of the display screen.
