Referring to FIG. 1 , an embodiment of the present disclosure provides a display component, which is applied to a terminal, and includes:

The light-emitting function layer 4 disposed between the metal cathode 1 of the terminal and the metal anode 2, the light-emitting function layer 4 includes:

a hole transport layer 41 and an electron transport layer 42;

a light-emitting layer disposed between the hole transport layer 41 and the electron transport layer 42. The light-emitting layer is provided with a light-emitting material 43 and an infrared sensing element, and the infrared sensing element transmits and receives an infrared signal for detecting a distance between the external object and the terminal;

Referring to FIG. 1, the metal anode 2 is connected to the positive electrode of a power source 3, the metal cathode 1 is connected to the negative electrode of the power source 3, and the metal anode 2 is disposed opposite to the hole transport layer 41. The metal cathode 1 and the electron transport layer 42 are disposed. Relative settings. When the power source 3 supplies an appropriate voltage, the positive electrode holes and the metal cathode charges are combined in the light-emitting layer, thereby causing the light-emitting material 43 in the light-emitting layer to be bright.

In the embodiment of the present disclosure, the external object refers to an operation body that can touch the screen of the terminal to input a touch signal, for example, a human limb, a joint of a person, and/or a stylus and other components; The external object may also be an object other than the operating body. Depending on the position of the infrared sensing element in the light-emitting layer and the difference in the setting angle, the infrared signal emitted by the infrared sensing element may be emitted to the operating body or may be emitted to other objects than the operating body. In some embodiments, the infrared signal transmitted and received by the infrared sensing element is used to detect the distance between the operating body and the terminal.

Terminals include, but are not limited to, mobile phones, tablets, laptops, PDAs, car terminals, wearable devices, and pedometers.

In the embodiment of the present disclosure, the distance between the external object and the terminal may be a vertical distance between the external object and the plane where the infrared sensing element is located, or a distance between the external object and the screen of the terminal. Wherein, the vertical distance between the external object and the plane of the infrared sensing element can be obtained by measurement. When the distance between the external object and the terminal is the distance between the external object and the screen of the terminal, it is required to detect the vertical relationship between the external object and the plane of the infrared sensing element according to the infrared signal transmitted and received by the infrared sensing element. Distance, to calculate. Specifically, the distance between the external object and the screen of the terminal is obtained by the following formula, wherein the formula is specifically:

Where H is the distance between the external object and the screen of the terminal, v is the propagation speed of the infrared signal transmitted and received by the infrared sensing element, and t is the time from the infrared light emitting element to the infrared light receiving to the infrared sensing element, and L is the infrared sensing The distance between the infrared emitting element 44 of the element and the infrared receiving element 45, h is the distance between the infrared sensing element and the screen of the terminal.

Moreover, in the embodiment of the present disclosure, when the terminal is in the blackout state, if the distance between the external object and the terminal is greater than or equal to the first predetermined distance, the screen area corresponding to the fingerprint collection area on the light emitting layer is extinguished. The screen state, and other areas of the light-emitting layer other than the screen area corresponding to the fingerprint collection area are also in a blackout state (that is, the entire light-emitting layer is in a blackout state). Moreover, in order to ensure that the user has a good visual experience, when the terminal is in the lighting state, the screen area corresponding to the fingerprint collection area on the illuminating layer is always in the lighting state.

According to the above display assembly provided by the embodiment of the present disclosure, since the infrared sensing element is added, the distance between the external object and the terminal can be detected, and when the distance between the external object and the terminal is less than the first predetermined distance So that the screen area corresponding to the fingerprint collection area on the illuminating layer is in a lighting state; and when the distance between the external object and the terminal is greater than or equal to the first predetermined distance, the illuminating layer is in a blackout state to reduce the The power consumption of the terminal. Moreover, since the luminescent material 43 in the screen area corresponding to the fingerprint collection area on the illuminating layer does not need to be in the illuminating state in the screen-off state, the service life of the luminescent material 43 in the screen area can be prolonged; When the distance between the terminal and the terminal does not satisfy the condition, the entire illuminating layer is in a blackout state, which can improve the user's visual experience and photographic experience.

Further, in the embodiment of the present disclosure, the infrared sensing element is disposed in a predetermined area in the light emitting layer, and the projection of the fingerprint collecting area on the light emitting layer is located in the predetermined area.

The predetermined area is a position on the illuminating layer corresponding to the fingerprint collection area of the terminal. The location of the predetermined area is also different depending on the location of the setting of the fingerprint collection area. For example, the predetermined area may be disposed at the bottom end, the middle portion, the top end of the light-emitting layer, and each position near the side of the light-emitting layer.

Specifically, in the embodiment of the present disclosure, the area of the predetermined area may be equal to the projected area of the fingerprint collection area on the light emitting layer or larger than the projected area of the fingerprint collection area on the light emitting layer. In some embodiments of the present disclosure, the area of the predetermined area is larger than the projected area of the fingerprint collection area on the luminescent layer.

Moreover, in the embodiment of the present disclosure, when the area of the predetermined area is equal to the projected area of the fingerprint collection area on the light-emitting layer, the shape of the predetermined area is the same as the shape of the fingerprint collection area, that is, the fingerprint collection area. The shape is a circle, and the shape of the predetermined area is a circle.

When the area of the predetermined area is larger than the projected area of the fingerprint collection area in the light-emitting layer, the shape of the predetermined area may be the same as or different from the shape of the fingerprint collection area.

Still further, in the embodiment of the present disclosure, the infrared sensing element includes an infrared emitting element 44 and an infrared receiving element 45, and the infrared emitting element 44 and the infrared receiving element 45 are symmetrically disposed in a predetermined area.

The infrared emitting element 44 is an infrared emitting sensor, and the infrared receiving element 45 is an infrared receiving sensor.

The infrared signal emitted from the infrared emitting element 44 passes through the hole transport layer 41 and the metal anode 2, and then passes through the glass cover of the terminal disposed on the upper side of the metal anode 2 to the position of the external object, and passes through the The external object reflects the infrared light to the infrared receiving element 45, and determines the actual distance of the infrared light transmission by the transmission time and the transmission speed of the infrared light.

The display component of the embodiment of the present disclosure transmits and receives an infrared signal through the infrared sensing element to detect a distance between the external object and the terminal, and controls the light emitting state of the screen area corresponding to the fingerprint collection area on the light emitting layer according to the distance. When the distance is not satisfied, the screen area is controlled to be in a blackout state, which can reduce the power consumption of the terminal, and at the same time, prolong the service life of the luminescent material 43 in the screen area, and improve the user experience.

The embodiment of the present disclosure further provides a terminal, including the above display component, the terminal further includes: a fingerprint collection area, and the fingerprint collection area is opposite to the metal cathode 1 .

Specifically, the fingerprint collection area refers to a fingerprint collection module of the terminal, which is used to collect a user fingerprint.

The infrared signal is sent and received by the infrared sensing element to detect the distance between the external object and the terminal, and the light-emitting state of the screen area corresponding to the fingerprint collection area on the light-emitting layer is controlled according to the distance. When the distance is not satisfied, the screen area is controlled to be in a blackout state, which can reduce the power consumption of the terminal, and at the same time, prolong the service life of the luminescent material 43 in the screen area, and improve the user experience.

Referring to FIG. 2, an embodiment of the present disclosure further provides a display control method, which is applied to a terminal, and includes:

Step 201: When the terminal is in the off-screen state, the infrared sensing element of the terminal transmits and receives an infrared signal, and detects a first distance between the external object and the terminal.

In the embodiment of the present disclosure, the terminal includes a display component, and the specific structure of the display component is consistent with the structure of the display component in the above embodiment, and details are not described herein. Similarly, in this embodiment, the external object is the same object as the external object in the embodiment of the display assembly, and details are not described herein.

Specifically, the first distance between the external object and the terminal may be a vertical distance between the external object and a plane where the infrared sensing element is located, or a distance between the external object and the screen of the terminal. The infrared sensing element transmits and receives the infrared signal, and detects the distance between the external object and the plane of the infrared sensing element, thereby obtaining the distance between the external object and the terminal screen.

Wherein, when the terminal is in the lighting state, the infrared sensing element does not transmit and receive the infrared signal, that is, at this time, the infrared sensing element is in a non-working state.

Step 202: If the first distance is smaller than the first predetermined distance, the screen area corresponding to the fingerprint collection area on the illumination layer of the control terminal is in a lighting state and the fingerprint collection module of the control terminal is in an active state.

If the first distance is greater than or equal to the first predetermined distance, it indicates that the user is less likely to perform fingerprint recognition. At this time, the screen area corresponding to the fingerprint collection area on the illuminating layer of the control terminal is off. The state is to reduce the use of the power of the terminal; at the same time, the luminescent material in the screen area is continuously kept in a light-emitting state, thereby prolonging the service life of the luminescent material and improving the user experience.

When the first distance is smaller than the first predetermined distance, it indicates that the user wants to perform fingerprint recognition. In this case, by controlling the screen area corresponding to the fingerprint collection area on the illuminating layer to be in a lighting state, the user is made The specific location of the fingerprint collection area can be observed in time and accurately, and the fingerprint collection module of the user is collected by the fingerprint collection module in the working state, thereby performing fingerprint identification work.

Referring to FIG. 3, in the embodiment of the present disclosure, the display control method further includes:

Step 203: Detect fingerprint information input in the fingerprint collection area.

The step 203 is specifically: reading different fingerprint information sensed when the operating body slides to different positions in the fingerprint collection area, and splicing the read different fingerprint information to obtain complete fingerprint information.

Since there is no need to obtain complete fingerprint information at one time, there is no specific requirement for the size of the fingerprint collection area, and the size of the fingerprint collection area can be adjusted according to the installation requirements of other components in the internal space of the terminal, thereby achieving savings. The effect of the internal space of the terminal.

Step 204: Perform fingerprint identification according to the fingerprint information, and perform display control according to the fingerprint recognition result.

After obtaining the complete fingerprint information input through the fingerprint collection area, the fingerprint information is compared with the pre-stored fingerprint information by a fingerprint, if the fingerprint comparison result between the two is greater than or equal to a predetermined threshold. Then, it is determined that the fingerprint recognition result is successful for fingerprint recognition, otherwise it is a failure.

The specific steps of performing display control according to the fingerprint identification result in the embodiment of the present disclosure include:

Step 2041: If the fingerprint recognition result is that the fingerprint recognition is successful, the area of the illumination layer of the control terminal other than the screen area corresponding to the fingerprint collection area is in a lighting state, and the fingerprint collection module of the control terminal is switched from the working state to the non-operational state. Working status

Step 2042: If the fingerprint recognition result is that the fingerprint recognition fails, the screen area corresponding to the fingerprint collection area on the light-emitting layer of the control terminal is switched from the lighting state to the blackout state.

Wherein, when the fingerprint recognition result is successful for fingerprint recognition, the terminal has completed fingerprint recognition. At this time, the fingerprint recognition module is no longer needed to continue working. Therefore, the control fingerprint collection module is switched from the working state to the non-working state, Reduce the power usage of the terminal. When the fingerprint recognition result is that the fingerprint recognition fails, the terminal cannot enter the standby mode. Therefore, the screen area corresponding to the fingerprint collection area on the illuminating layer of the control terminal is switched to the blackout state, and the power consumption of the terminal is also reduced.

Moreover, in the embodiment of the present disclosure, when the fingerprint recognition result is that the fingerprint recognition fails, the fingerprint collection module of the terminal continues to be in a non-working state.

Referring to FIG. 4, in the embodiment of the present disclosure, the display control method further includes:

Step 205: Detect the ambient light brightness of the environment in which the terminal is currently located and the second distance between the terminal and the external object.

The detection of the ambient lightness of the environment in which the terminal is currently located is measured by the photosensitive sensor carried on the terminal, and the detection of the second distance between the terminal and the external object is detected by the infrared proximity sensor disposed at the top of the terminal. acquired.

In some embodiments of the present disclosure, the external object in step 205 and the external object in step 201 are not the same object. For example, the external object in step 201 is an operating body (such as a user's finger). The external objects in 205 are other objects (which may be other limbs of the user, clothes worn by the user, bags carried by the user, and other items other than the user).

Step 206: Determine, according to the ambient light brightness and the second distance, whether the terminal is in a predetermined mode.

Specifically, the predetermined mode refers to a state in which the terminal is not wrapped by an external object, for example, a state in which the terminal is placed in a pocket and wrapped by the clothes; or the terminal is in a state of being placed in the protective cover and wrapped by the protective cover.

Specifically, the step 206 is specifically:

If the ambient light brightness is less than the predetermined ambient light brightness and the second distance is less than a second predetermined distance, it is determined that the terminal is in the predetermined mode; otherwise, the terminal is not in the predetermined mode.

In this step 206, the second predetermined distance determined by the second distance may be the same as the value of the first predetermined distance in step 202, or may be different. In some embodiments of the present disclosure, the first predetermined distance and the second predetermined distance are different.

Step 207, if not, controlling the infrared sensing element to be in an active state.

In the embodiment of the present disclosure, when the terminal is in the state of the predetermined mode, the infrared sensing elements are all in a non-working state to reduce the power usage of the terminal.

When the fingerprint recognition result is that the fingerprint recognition fails, the infrared sensing element continues to be in a working state to ensure continuous detection of the first distance between the external object and the terminal; and at the same time, when the fingerprint recognition result is successful for fingerprint recognition, the infrared sensing The component no longer needs to transmit and receive infrared signals, and therefore, the infrared sensing component is controlled to be in an inoperative state to reduce the power usage of the terminal.

In the embodiment of the present disclosure, the display control method further includes:

Step 209: Detect the number of unlocking failures of the fingerprint collection module in a predetermined period of time before the work;

If the number of times of the unlocking failure is less than the predetermined number of times, the step of executing the screen area corresponding to the fingerprint collection area on the illuminating layer of the control terminal is in a lighting state, and the step of controlling the fingerprint collection module of the terminal is in an active state;

If the number of unlocking failures is greater than or equal to the predetermined number of times, the step of transmitting and receiving the infrared signal through the infrared sensing element and detecting the first distance between the external object and the terminal is performed after the predetermined time is delayed.

When the number of unlocking failures of the fingerprint collection module in the predetermined time period before the work is greater than or equal to the predetermined number of times, it indicates that the user has been unable to complete the fingerprint unlocking. At this time, the step of detecting and identifying the fingerprint information is not entered, but is delayed. After the predetermined time, the step of detecting the first distance between the external object and the terminal is performed again, so that the user processes the finger (such as scrubbing, decontamination processing, etc.) in the predetermined interval to improve fingerprint recognition. Success rate.

When the fingerprint recognition result is displayed as the fingerprint identification success, the stored fingerprint collection module deletes the number of unlocking failures within a predetermined time period before the work.

The display control method provided by the embodiment of the present disclosure transmits and receives an infrared signal through the infrared sensing element to detect a first distance between the external object and the terminal, and according to the first distance, a screen area corresponding to the fingerprint collection area on the light emitting layer. The lighting state is controlled. When the distance is not satisfied, the screen area is controlled to be in a blackout state, which can reduce the power consumption of the terminal, and at the same time, prolong the service life of the luminescent material in the screen area, and improve the user experience.
