When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The terminal is usually provided with a fingerprint sensor, and in the conventional terminal, the fingerprint sensor is arranged on a front panel of the terminal and is located in a non-display area of the terminal, so that the area of the non-display area of the terminal is large, and the area of the display area is small, and full-screen display of the terminal is difficult to realize. Furthermore, in conventional terminals, the fingerprint sensor may also be arranged on the back side of the terminal, but this may affect the user experience.
In the related art, in order to realize full-screen display of the terminal and improve user experience, the fingerprint sensor can be arranged in a display panel of the terminal, and a control component of the terminal drives a fixed sub-pixel of the display panel to emit light to display fingerprint prompt information, so that the position of the fingerprint sensor is prompted to a user. However, this technique requires the fixed sub-pixels of the display panel to be in an on state for a long time, which causes the fixed sub-pixels to be easily burned out, and the display panel to be easily subjected to a "burn-in phenomenon".
The embodiment of the disclosure provides a terminal and a display control method, wherein a fingerprint sensor of the terminal is arranged in a display panel of the terminal, and a control component of the terminal can drive a plurality of sub-pixels corresponding to an information screen display area of the display panel to alternately emit light to display fingerprint prompt information, so that the position of the fingerprint sensor is indicated for a user, and the display panel is prevented from being burnt. The terminal provided by the embodiment of the disclosure can be a smart phone, a tablet computer, a smart television, a smart watch, a multimedia player, an e-reader, a wearable device, or the like.
Fig. 1 is a schematic diagram illustrating a structure of a terminal 01 according to an exemplary embodiment, fig. 2 is a front view of a terminal 01 according to an exemplary embodiment, and fig. 3 is a cross-sectional view of a terminal according to an exemplary embodiment, in conjunction with fig. 1 to 3, the terminal 01 includes: control assembly 011, display panel 012 and fingerprint sensor 013, fingerprint sensor 013 sets up in display panel 012, and control assembly 011 is connected with fingerprint sensor 013 and display panel 012 respectively, and control assembly 011 is configured as:
determining a plurality of sub-pixels corresponding to a message screen display area of the display panel 012;
when the terminal 01 is in the message screen display mode, the plurality of sub-pixels are driven to alternately emit light to control the display panel 012 to display the fingerprint indicating information indicating the position of the fingerprint sensor 013 in the message screen display area of the display panel 012.
To sum up, in the terminal provided in the embodiment of the present disclosure, since the control component drives the plurality of sub-pixels corresponding to the information screen display area of the display panel to alternately emit light to display the fingerprint prompt information, the fixed sub-pixels of the display panel can be prevented from being in the on state for a long time, and then the display panel is prevented from being burned.

Under the AOD mode, the power consumption of the terminal can be controlled at a lower level, and the effect of saving power is achieved. In the disclosed embodiment, the touchscreen display area may include a forward projection area of the fingerprint sensor 013 on the display panel 012, for example, the touchscreen display area may include area D in fig. 2. The fingerprint hint information can be a fingerprint hint pattern, a fingerprint hint picture, textual information, or any other information that can be used to indicate the location of the fingerprint sensor 013. Illustratively, the fingerprint hint information can be a fingerprint hint pattern.
Optionally, in this embodiment of the disclosure, the control component 011 may be a Processor or a display control chip, the Processor may be a general-purpose Processor or a special-purpose Processor, the general-purpose Processor may be a Central Processing Unit (CPU), and the special-purpose Processor may be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or the like. The display control chip may be a timing controller. In practical applications, the control component 011 may also be a Micro Control Unit (MCU), which is also called a Single Chip Microcomputer (SCM) or a Single Chip Microcomputer, and the MCU is a Microcomputer that appropriately reduces the frequency and specification of the CPU, and integrates peripheral interfaces such as a memory, a counter (Timer), a Universal Serial Bus (USB), an Analog/digital (a/D) converter, a Universal asynchronous Receiver/Transmitter (PLC), a Direct Memory Access (DMA), and the like, even a display panel driving circuit on a Single Chip, to form a computer with a Single Chip level.
In the embodiment of the present disclosure, the message display area includes an orthographic projection area of the fingerprint sensor 013 on the display panel 012, and the control component 011 can determine the orthographic projection area of the fingerprint sensor 013 on the display panel 012, then determine the sub-pixels located in the orthographic projection area as the sub-pixels corresponding to the message display area, and further drive the sub-pixels corresponding to the message display area to alternately emit light when the terminal 01 is in the message display mode. Alternatively, the control component 011 may determine the sub-pixels located in the region D shown in fig. 2 as a plurality of sub-pixels corresponding to the screen display region.
The display panel 012 may be an Organic Light-Emitting Diode (OLED) panel, a sub-pixel of the OLED display panel includes a Thin Film Transistor (TFT), an anode, an Organic Light-Emitting unit, and a cathode, and the OLED display panel further includes a gate line and a data line, a gate of the TFT is connected to the gate line, a source of the TFT is connected to the data line, a drain of the TFT is connected to the anode, a control component 011 can be connected to the gate line and the data line, and the control component 011 can control the TFT to be turned on and turned off by the gate line and the gate of the TFT, so as to control the sub-pixel to be turned on and turned off. In an embodiment of the present disclosure, the control component 011 driving sub-pixel to emit light may include: the control component 011 controls the sub-pixels to be turned on, and applies a driving voltage to the sub-pixels through the data lines, and under the action of the driving voltage, the organic light emitting units of the sub-pixels emit light, so that the sub-pixels emit light. The control component 011 can control the plurality of sub-pixels to alternately emit light by controlling the plurality of sub-pixels to be alternately turned on, or the control component 011 can control the plurality of sub-pixels to alternately emit light by alternately applying a driving voltage to the plurality of sub-pixels. Among them, the magnitude of the driving voltage may be used to indicate the luminance of the sub-pixel, and the driving voltage may have a positive correlation with the luminance of the sub-pixel regardless of the electro-optical conversion efficiency (efficiency of converting an electric signal into an optical signal) of the sub-pixel.
As is apparent from the above description, the OLED display panel realizes light emission of the sub-pixels by converting an electric signal into an optical signal through the organic light emitting unit. In practical applications, under the influence of the electro-optic conversion efficiency of the organic material forming the organic light emitting unit, when a certain sub-pixel of the OLED display panel is in an on state for a long time, the lifetime of the sub-pixel may be rapidly reduced, which eventually causes the sub-pixel to fail to emit light (or the sub-pixel is burned out), and the OLED display panel may generate a "burn-in phenomenon". In the embodiment of the present disclosure, when the terminal 01 is in the osd mode, the control component 011 drives the plurality of sub-pixels corresponding to the osd display area of the display panel 012 to alternately emit light, so that a certain sub-pixel can be prevented from being turned on for a long time, and the sub-pixel is prevented from being burned out, thereby preventing the "burn-in" of the display panel in the osd mode.
Optionally, the control component 011 is configured to: when the terminal 01 is in a screen display mode, determining a sub-pixel corresponding to each light-emitting period in a plurality of sub-pixels, wherein the sub-pixels corresponding to any two adjacent light-emitting periods are different; in each light emitting period, the sub-pixels corresponding to each light emitting period are controlled to be turned on, and the sub-pixels except the sub-pixels corresponding to each light emitting period in the plurality of sub-pixels are controlled to be turned off, so that the display panel 012 is controlled to display the fingerprint prompt information in the information screen display area. And the fingerprint prompt messages displayed in any two adjacent light-emitting periods are the same or different.
When the control assembly 011 drives a plurality of sub-pixels to alternately emit light and the time lengths of the adjacent two times of driving the sub-pixels to emit light are equal, a light emitting period may be formed, which may be determined according to the electro-optical conversion efficiency of the organic material forming the organic light emitting unit of the sub-pixel, for example, may be 3 seconds, 5 seconds, 8 seconds, or the like. In this embodiment of the present disclosure, the fingerprint prompting information displayed in any two adjacent light emitting periods is the same or different, and the fingerprint prompting information may be a fingerprint prompting pattern, the control component 011 may determine the sub-pixel corresponding to each light emitting period in the plurality of sub-pixels in the display area of the information screen according to the fingerprint prompting pattern corresponding to each light emitting period, so that the sub-pixels corresponding to any two adjacent light emitting periods are different, and the pattern displayed on the display panel 012 when the sub-pixel corresponding to each light emitting period emits light is the fingerprint prompting pattern corresponding to the light emitting period. After the control component 011 determines the sub-pixels corresponding to each lighting period, the control component can control the corresponding sub-pixels to be turned on and the other sub-pixels to be turned off in the corresponding lighting period, so as to control the display panel 012 to display the fingerprint prompt information in the information screen display area.
For example, when the terminal 01 is in the message screen display mode, the embodiment of the present disclosure takes the fingerprint prompting information displayed in any two adjacent light emitting periods as the same, and takes the fingerprint prompting information as the fingerprint prompting pattern to describe that the control module 011 controls the display panel 012 to display the fingerprint prompting information in the message screen display area of the display panel 012. Referring to fig. 4 and 5, which illustrate schematic views of fingerprint prompting patterns displayed in two adjacent lighting periods provided by the embodiment of the present disclosure, in a first lighting period, the control component 011 controls the display panel 012 to display a fingerprint prompting pattern P1 shown in fig. 4 in the message screen display area D of the display panel 012, and in a second lighting period, the control component 011 controls the display panel 012 to display a fingerprint prompting pattern P2 shown in fig. 5 in the message screen display area D of the display panel 012, where the fingerprint prompting pattern P1 is the same as the fingerprint prompting pattern P2, but the display position of the fingerprint prompting pattern P1 in the message screen display area D is different from the display position of the fingerprint prompting pattern P2 in the message screen display area D. The first light-emitting period and the second light-emitting period are two adjacent light-emitting periods.

The display panel may be an OLED display panel, a sub-pixel of the OLED display panel includes a TFT, an anode, an organic light emitting unit, and a cathode, and a light emitting period may be determined according to an electro-optical conversion efficiency of an organic material forming the organic light emitting unit of the sub-pixel, for example, the light emitting period may be 3 seconds, 5 seconds, or 8 seconds, and the embodiment of the disclosure is not limited thereto.
In sub-step 1022, in each light-emitting period, the sub-pixel corresponding to each light-emitting period is controlled to be turned on, and the sub-pixels except the sub-pixel corresponding to each light-emitting period in the plurality of sub-pixels are controlled to be turned off, so as to control the display panel to display the fingerprint prompt information in the display area of the information screen.
After the control component determines the sub-pixels corresponding to each light-emitting period, the sub-pixels corresponding to each light-emitting period can be controlled to be turned on and the rest of the sub-pixels can be controlled to be turned off in each light-emitting period, and the sub-pixels can emit light after being turned on, so that the display panel can display the fingerprint prompt information.
In the embodiment of the disclosure, the display panel may be an OLED display panel, a subpixel of the OLED display panel includes a TFT, an anode, an organic light emitting unit and a cathode, the OLED display panel further includes a gate line and a data line, a gate of the TFT is connected to the gate line, a source of the TFT is connected to the data line, a drain of the TFT is connected to the anode, the control component may be connected to the gate line and the data line, and the control component may control the TFT to be turned on and turned off through the gate line and the gate of the TFT, so as to control the subpixel to be turned on and turned off. In an embodiment of the present disclosure, the driving, by the control component, the sub-pixel corresponding to each light-emitting period to emit light may include: the control component controls the sub-pixels to be started, and applies driving voltage to the sub-pixels through the data lines, and under the action of the driving voltage, the organic light-emitting units of the sub-pixels emit light, so that the sub-pixels emit light. Wherein, the magnitude of the driving voltage can be used to indicate the luminance of the sub-pixel, and the driving voltage can be positively correlated with the luminance of the sub-pixel without considering the electro-optical conversion efficiency of the sub-pixel.
For example, in the embodiment of the present disclosure, the fingerprint prompting information displayed in any two adjacent light emitting periods is the same, and the fingerprint prompting information is taken as a fingerprint prompting pattern to describe that the control component controls the display panel to display the fingerprint prompting information in the information screen display area of the display panel. In the first lighting period, the control component may control the display panel to display a fingerprint prompting pattern P1 shown in fig. 4 in the message screen display area D of the display panel, and in the second lighting period, the control component may control the display panel to display a fingerprint prompting pattern P2 shown in fig. 5 in the message screen display area D of the display panel, where the fingerprint prompting pattern P1 is the same as the fingerprint prompting pattern P2, but a display position of the fingerprint prompting pattern P1 in the message screen display area D is different from a display position of the fingerprint prompting pattern P2 in the message screen display area D. The first light-emitting period and the second light-emitting period are two adjacent light-emitting periods.
In step 103, the value of the pressure exerted by the user on the display panel is detected by the pressure sensor.
The pressure sensor is arranged in the display panel, when a user presses the display panel, the pressure sensor can detect the pressure value, the pressure sensor can use the detected pressure value as the pressure value applied to the display panel by the user, and the pressure value applied to the display panel by the user is sent to the control assembly, so that the control assembly can detect the pressure value applied to the display panel by the user through the pressure sensor.
In the embodiment of the disclosure, when the pressure sensor is arranged in the display panel and is positioned below the fingerprint sensor, the pressure of the user pressing the display panel is transmitted to the pressure sensor through the display panel and the fingerprint sensor in sequence, so that the pressure sensor can detect the value of the pressure; when pressure sensor sets up in display panel, and pressure sensor and fingerprint sensor are the same layer setting, the pressure that the user pressed display panel passes through display panel and transmits to pressure sensor's value can be detected to pressure sensor.
It should be noted that, in the embodiment of the present disclosure, the pressure sensor may be a pressure sensor, and when a user presses the display panel, a pressure applied on the display panel by the user may be transmitted to the pressure sensor, so that the pressure sensor generates a deformation, and the pressure sensor detects a value of the pressure by converting a deformation signal into an electrical signal. Generally, the value of the pressure is linear with the amount of deformation of the pressure sensor.
In step 104, it is determined whether the value of the pressure applied by the user on the display panel is greater than a preset pressure value. When the value of the pressure applied on the display panel by the user is greater than the preset pressure value, executing step 105; when the value of the pressure applied on the display panel by the user is not greater than the preset pressure value, step 107 is executed.
The control assembly can be stored with a preset pressure value, and after the control assembly detects the value of the pressure applied to the display panel by the user, whether the value of the pressure applied to the display panel by the user is larger than the preset pressure value or not can be judged. Alternatively, the control component may compare the value of the pressure applied by the user on the display panel with a preset pressure value to determine whether the value of the pressure applied by the user on the display panel is greater than the preset pressure value.
In step 105, the sub-pixels corresponding to all the light emitting periods in the plurality of sub-pixels are controlled to be turned on, so as to control the display panel to display the complete fingerprint prompt information in the display area of the information screen.
In the embodiment of the disclosure, the fingerprint prompt information displayed by the display panel in each lighting period may be partial fingerprint prompt information, and when the control component determines that the value of the pressure applied to the display panel by the user is greater than the preset pressure value, the control component considers that fingerprint identification is required, so that, for better prompting the user and better fingerprint acquisition, the control component may control the sub-pixels corresponding to all lighting periods to be turned on, so as to control the display panel to display complete fingerprint prompt information in the display area of the information screen. The process of the control component controlling the turn-on of the sub-pixels corresponding to all the light emitting periods is the same as the process of the control component controlling the turn-on of the sub-pixels corresponding to each light emitting period, and the embodiment of the disclosure is not repeated herein.
In an example, the fingerprint prompting information displayed in any two adjacent light emitting periods forms complete fingerprint prompting information, and the fingerprint prompting information is taken as a fingerprint prompting pattern to explain that the control component controls the display panel to display the complete fingerprint prompting information in the information screen display area of the display panel. The control component may control the display panel to display the complete fingerprint prompting pattern P shown in fig. 9 in the information screen display area D of the display panel, and as can be determined by combining fig. 4, 5 and 9, the fingerprint prompting pattern P1 shown in fig. 4 and the fingerprint prompting pattern P2 shown in fig. 5 are both partial fingerprint prompting patterns, and the fingerprint prompting pattern P1 and the fingerprint prompting pattern P2 constitute the complete fingerprint prompting pattern P shown in fig. 9.
In step 106, fingerprint information is collected by a fingerprint sensor.
After control assembly control display panel shows complete fingerprint prompt message in the news screen display area, the user can press on display panel according to the fingerprint sensor's that the fingerprint prompt message that display panel shows instruction position, and control assembly can gather fingerprint information through fingerprint sensor.
In an embodiment of the present disclosure, the fingerprint sensor may include at least one of an optical fingerprint sensor and an ultrasonic fingerprint sensor. When the fingerprint sensor comprises the optical fingerprint sensor, when a finger of a user presses the display panel, light emitted by an information screen display area of the display panel can be refracted and/or reflected on the fingerprint of the user, and the optical fingerprint sensor can collect the fingerprint according to the received light refracted and/or reflected by the fingerprint of the user; when fingerprint sensor includes ultrasonic fingerprint sensor, when user's finger pressed display panel, can form electric capacity (or inductance) between user's finger and the ultrasonic fingerprint sensor, because the existence of fingerprint, the finger surface is unsmooth, electric capacity (or inductance) that forms between the regional area of salient point place on the finger and the ultrasonic fingerprint sensor and the electric capacity (or inductance) that forms between the regional area of salient point place and the ultrasonic fingerprint sensor are different in size, ultrasonic fingerprint sensor can be according to the electric capacity (or inductance) that forms between the different regions of finger and the ultrasonic fingerprint sensor, carry out the collection of fingerprint.
It should be noted that, after the fingerprint information is collected, the control component may perform fingerprint identification according to the collected fingerprint information to perform authentication on the user, so as to unlock the terminal according to the authentication result or complete operations such as payment according to the authentication result. Optionally, preset fingerprint information may be stored in the control component, the control component may match the collected fingerprint information with the preset fingerprint information to perform fingerprint identification, and if the collected fingerprint information matches the preset fingerprint information, the fingerprint identification is successful, so that the identity authentication is successful, and the control component unlocks the terminal or completes operations such as payment. The preset fingerprint information is fingerprint information which is acquired by the fingerprint sensor in advance and stored in the control assembly.
In the embodiment of the present disclosure, when the value of the pressure applied to the display panel 012 by the user is greater than the preset pressure value, the control component collects fingerprint information through the fingerprint sensor, so as to avoid fingerprint collection caused by the user mistakenly touching the display panel, thereby facilitating effective fingerprint identification.
In step 107, no fingerprint information is collected
When the value of the pressure applied to the display panel by the user is not greater than the preset pressure value, the control assembly considers that fingerprint identification is not required, and therefore the control assembly does not perform fingerprint acquisition.
It should be noted that, the sequence of the steps of the terminal control method provided in the embodiment of the present disclosure may be appropriately adjusted, and the steps may also be increased or decreased according to the circumstances, and any method that can be easily conceived by a person skilled in the art within the technical scope of the present disclosure shall be included in the protection scope of the present disclosure, and therefore, no detailed description is given here.
