As shown in FIG. 1 , an embodiment of the present disclosure provides a method for unlocking a display screen of an air conditioner, and the air conditioner is equipped with a display screen and a fingerprint module. The fingerprint module is located on the backlight side of the display and is equipped with an image sensor. The method includes:

S01. Obtain a touch signal carrying unlocking information.

S02, when the touch signal indicates that the user has an unlocking demand, control the display screen to switch to a constant light state, so as to reinforce the light of the fingerprint module.

S03. If the unlocking information matches the preset unlocking information, control the fingerprint module to be turned on.

S04. Extract current fingerprint information from the unlocking information, where the current fingerprint information is collected and generated by an image sensor.

S05, control the display screen to unlock according to the current fingerprint information.

Using the method for unlocking the display screen of an air conditioner provided by the embodiments of the present disclosure, after the air conditioner acquires a touch signal carrying unlock information, and when it is determined according to the touch signal that the user has an unlocking demand, the control display screen is switched to a always-on state, Therefore, the fingerprint module can be reinforced with light through the display screen, so that the image sensor can extract the current fingerprint information from the unlocking information, and control the display screen to perform the unlocking operation according to the current fingerprint information. In this way, this method makes it possible to control the display screen to switch to the always-on state only when it is determined that the user has an unlocking demand, and the image sensor can collect fingerprint information by reinforcing the light of the fingerprint module, that is, the display screen is not continuously on. The constant light state reduces the power consumption during the unlocking process of the display screen of the air conditioner.

In addition, the existing unlocking method of the air conditioner also includes LCD (Liquid Crystal Display, liquid crystal display). Since the LCD does not support fingerprint detection under the screen, it is necessary to add a fingerprint module. Specifically, a capacitive fingerprint module is installed on the frame of the air conditioner, which will inevitably increase the space occupied by the air conditioner. In this method, the fingerprint module is installed on the backlight side of the display screen, so the display screen supports fingerprint detection under the screen, and therefore, the space occupied by the air conditioner will not be increased.

Optionally, the display screen may be an OLED (Organic Light-Emitting Diode, organic electro-laser display) display screen or an AMOLED display screen. The fingerprint module may be an optical fingerprint module, and the image sensor may be a CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) image sensor. Among them, the optical fingerprint module also includes peripheral components of the optical fingerprint module, connectors and other components. As an example, the display screen can be used as a component of a display screen module of an air conditioner, and the display screen module includes a cover plate, an adhesive layer, an OLED display screen, and an optical fingerprint module sequentially arranged along the incident direction of light. Among them, the adhesive layer is OCA (Optically Clear Adhesive, optical glue).

Optionally, as shown in FIG. 2 , an unlocking area is provided on the light-facing side of the display screen. The fingerprint module is located on the backlight side of the unlocking area. The unlocking information includes touch pressure information. Determine that the user has an unlock need as follows:

S11, if the touch signal of the touch unlocking area is acquired, acquire touch pressure information.

S12. If the touch pressure information matches the preset pressure information, it is determined that the user has an unlocking demand.

In this way, although the touch signal carries unlock information, the air conditioner may receive a falsely triggered unlock signal sent by the user. Therefore, the air conditioner first judges whether the touch signal of the touch unlock area has been obtained. The touch signal in the area indicates that the user does not have an unlocking requirement, and there is no need to perform subsequent unlocking operations. If the touch signal of the touch unlocking area is obtained, the touch pressure information contained in the unlock information is further obtained, and when the touch pressure information matches the preset pressure information, it can be determined that the user has an unlocking demand.

Wherein, the air conditioner may judge whether to obtain a touch signal for touching the unlocked area by scanning the unlocked area. As an example, the scanning frequency is 30-60 Hz (Hertz).

Optionally, the touch pressure information matches the preset pressure information, which may be that the touch pressure information is greater than or equal to the preset pressure information, or that the touch pressure information is within a preset range corresponding to the preset pressure information. The embodiments of the present disclosure may not be specifically limited.

In practical applications, both the touch pressure information and the preset pressure information may be pressure values, or may be numerical values having a functional relationship with the pressure values. For example, the preset pressure information is a pressure value of 500. When the touch pressure information is greater than the pressure value of 500, it is determined that the user has an unlocking demand.

Optionally, an unlocking area is provided on the light-facing side of the display screen. The fingerprint module is located on the backlight side of the unlocking area. Controlling the display screen to switch to a constant light state, including:

Controlling the display screen area corresponding to the unlocking area to switch to a constant light state.

In this way, the method enables the air conditioner to control the display area corresponding to the unlocked area to switch to a constant light state when it is determined that the user has an unlocking demand, instead of controlling all areas of the display screen to be always on, and only controls the display area associated with the unlocked area Keeping it on can realize light reinforcement for the fingerprint module, which can further reduce the power consumption during the unlocking process of the air conditioner display.

Optionally, the display screen has a visible display area. The unlocking area is located in the lower half of the visible display area, and the area of the unlocking area is greater than or equal to the first threshold and less than or equal to the second threshold. Wherein, the first threshold and the second threshold can be set according to the size of the fingerprint area of the user. As an example, the first threshold is the area of the user's thumbprint, and the second threshold is N times the area of the user's thumbprint. N is greater than or equal to 2. In addition, the unlocking area can be circular or square. Regarding the location and shape of the unlocking area, this embodiment of the present disclosure may not specifically limit it.

As shown in FIG. 3 , an embodiment of the present disclosure further provides a method for unlocking a display screen of an air conditioner, and the air conditioner is equipped with a display screen and a fingerprint module. The fingerprint module is located on the backlight side of the display and is equipped with an image sensor. The method includes:

S21. Acquire a touch signal carrying unlocking information, where the unlocking information includes location information.

S22, when the touch signal indicates that the user has an unlocking demand, control the display screen to switch to a constant light state, so as to reinforce the light of the fingerprint module.

S23. If the location information is located in the preset fingerprint collection area, determine that the unlock information matches the preset unlock information, where the preset unlock information includes the preset fingerprint collection area.

S24, controlling the fingerprint module to be turned on.

S25. Extract current fingerprint information from the unlocking information, where the current fingerprint information is collected and generated by an image sensor.

S26. Control the display screen to unlock according to the current fingerprint information.

Using the method for unlocking the display screen of an air conditioner provided by an embodiment of the present disclosure, the air conditioner compares the location information included in the unlock information with the preset fingerprint collection area, and can determine that the unlocked location information is within the fingerprint collection area when the location information is within the fingerprint collection area. The information matches the preset unlocking information, and at this time, the control fingerprint module is turned on. In this way, the occurrence of unlocking the display screen by someone other than the user can be avoided, and the reliability of unlocking the display screen is improved on the basis of reducing power consumption during the unlocking process of the display screen of the air conditioner.

Optionally, the preset fingerprint collection area may coincide with the unlocking area, or may be located within the unlocking area. The embodiments of the present disclosure may not be specifically limited.

As an example, the location information may be coordinate information. The preset fingerprint collection area may be a preset coordinate system. By checking whether the coordinate information is within the preset coordinate system, it can be determined whether the unlock information matches the preset unlock information.

Optionally, as shown in Figure 4, according to the current fingerprint information, control the display screen to unlock, including:

S31. Extract feature data from current fingerprint information.

S32. If the feature data matches the preset feature data, control the display screen to unlock.

In this way, since the characteristic data can more accurately represent the differences of different types of fingerprint information, the unlocking operation of the display screen can be controlled by extracting the characteristic data and comparing it with the preset characteristic data. Based on the power consumption during the screen unlocking process, the reliability of display screen unlocking is improved.

Optionally, the feature data includes finger peak data and/or finger valley data.

Optionally, the feature data matches the preset feature data, which may be that the feature data is the same as the preset feature data, or that the similarity between the feature data and the preset feature data is greater than or equal to the preset similarity. Wherein, the preset similarity may be 96%-99%.

Optionally, the method also includes:

If the preset feature data of the feature data does not match, new current fingerprint information is acquired again, and the display screen is controlled to unlock according to the new current fingerprint information.

In this way, when the display screen is unsuccessfully unlocked for the first time, a second operation can be performed.

Wherein, the air conditioner can set a preset number of times to reacquire new current fingerprint information. The preset number of times may be 3-5 times. If the air conditioner fails to unlock the display screen within a preset number of times, it can control the display screen to lock.

An embodiment of the present disclosure also provides a display screen unlocking system for an air conditioner, including a display screen module, a fingerprint module, and a controller. The display module is configured with a display. The fingerprint module is located on the backlight side of the display and is equipped with an image sensor. The controller is connected with the display screen and the fingerprint module, and is used to obtain the touch signal sent by the user to touch the unlocking area. The touch signal carries unlocking information. When the touch signal indicates that the user has an unlocking demand, the display screen is controlled. Switch to the always-on state to strengthen the light of the fingerprint module. When the unlock information matches the preset unlock information, control the fingerprint module to open, extract the current fingerprint information from the unlock information, and the current fingerprint information is collected by the image sensor. Generate, and control the display to unlock according to the current fingerprint information.

Wherein, the controller is connected to the display screen, which may be a communication connection between the controller and the display screen. The controller is connected with the image sensor, which can be the communication connection between the controller and the fingerprint module. The present disclosure does not specifically limit the connection manner between the controller and the display screen and/or the fingerprint module.

Using the display screen unlocking system for the air conditioner provided by the embodiment of the present disclosure, after the controller obtains the touch signal carrying the unlock information, and determines according to the touch signal that the user has an unlocking demand, the control screen is switched to the always-on state, Therefore, the fingerprint module can be reinforced with light through the display screen, so that the image sensor can extract the current fingerprint information from the unlocking information, and control the display screen to perform the unlocking operation according to the current fingerprint information. In this way, the system only controls the display screen to switch to the always-on state only when it is determined that the user has an unlocking demand, and the image sensor can collect fingerprint information by reinforcing the light of the fingerprint module, that is, the display screen is not continuously on. The constant light state reduces the power consumption during the unlocking process of the display screen of the air conditioner.

Optionally, an avoidance layer is provided between the light-facing side of the fingerprint module and the display screen.

In this way, the intensity of light entering the image sensor through the display screen will not be too strong, so that the accuracy of the detection result of the fingerprint module is higher.

Wherein, the escape layer may be a void.

In practical applications, the air conditioner is equipped with an OLED display. Under the same experimental conditions, experiments were carried out on the standby power consumption of the display screen when the display screen was always on and the display standby power consumption using the method for unlocking the display screen of the air conditioner. The corresponding power consumption of the display screen is 4.6 mA, and the standby power consumption of the display screen corresponding to the unlocking method for the display screen of the air conditioner is 3.0 mA. In this way, the standby power consumption of the display is increased by 35%.

In this way, for seasons in which centralized heating or cooling is required in summer or winter, the standby power consumption of the display screen of the air conditioner can be effectively increased by adopting the display screen unlocking method for the air conditioner.
