Description

Technical Field

[0001] This application relates to the field of digital product technology, specifically to an electronic device and a control method. Background Technology

[0002] In the prior art, electronic devices with fingerprint recognition function achieve fingerprint recognition by placing a fingerprint recognition chip below the OLED (Organic Light-Emitting Diode) display screen of the electronic device.

[0003] To ensure users can align their fingerprints with the area where the fingerprint sensor is located during fingerprint recognition, a fingerprint icon corresponding to that location needs to be displayed on the screen. However, maintaining the fingerprint icon's visibility even when the screen is off presents a significant challenge. Current technologies typically employ a method of keeping a portion of the OLED display constantly lit to illuminate the fingerprint icon. However, this shortens the lifespan of the area of ​​the screen component that is constantly illuminated, consequently reducing the overall lifespan of the display. Summary of the Invention

[0004] This application aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] This application aims to provide an electronic device and a control method that at least solves the problem of shortened screen life caused by part of the display screen remaining on for extended periods when displaying indicator icons.

[0006] In a first aspect, embodiments of this application propose an electronic device, comprising: a screen assembly; an identification component disposed on one side of the screen assembly, the identification component being used to identify the biometric features of a user; and a display component disposed on the side of the identification component facing the outside, the display component being disposed opposite to the identification component. In a first state, the display component is capable of displaying an indicator icon under ambient light; in a second state, the display component is capable of transmitting light to the identification component so that the identification component can identify biometric features.

[0007] Secondly, embodiments of this application propose a control method for an electronic device, used in the electronic device described in the first aspect of this application. The electronic device includes a second light sensor for detecting the light intensity of ambient light, and a screen assembly includes a light-emitting layer. The control method includes: controlling the second light sensor to detect the light intensity of ambient light; and controlling the light-emitting layer to operate to display an indicator icon when the light intensity of ambient light is lower than a second preset value.

[0008] Thirdly, embodiments of this application propose a control method for an electronic device, used in the electronic device described in the first aspect of this application. The display component includes a accommodating member, each accommodating member containing multiple dye particles movable between their respective first and second positions. The display component includes multiple second electrode plates for driving the movement of the dye particles. Two of the multiple second electrode plates corresponding to any accommodating member are arranged opposite to each other. The electronic device includes a first light sensor for detecting the light intensity of reflected light from a user's biometric features reflected into the recognition component. The control method includes: controlling one of the two second electrode plates corresponding to any accommodating member to be charged, so that the multiple dye particles in the accommodating member corresponding to the second electrode plate move to the first or second position; controlling the first light sensor to detect the light intensity of the reflected light; and when the light intensity of the reflected light is lower than a first preset value, switching the charge loading state of at least some of the two second electrode plates corresponding to the accommodating member, so that the multiple dye particles in the accommodating member move from the first position to the second position, or from the second position to the first position. In embodiments of this application, the electronic device includes a screen component, a recognition component, and a display component. The screen component is oriented towards the user and is used to display various screen information to the user. The screen assembly can be an OLED display. Further, the recognition component is located on one side of the screen assembly, specifically on the side of the screen assembly facing away from the outside. The recognition component is used to identify the user's biometric features. When the user is within a certain range in front of the screen assembly, the recognition component can receive the reflected light from the user's biometric features. The recognition component confirms whether the user's biometric features match a preset biometric feature based on the reflected light. If the user's biometric features match the preset biometric feature, the electronic device can perform the corresponding function. The biometric feature can be a fingerprint, pupil, or other biometric features.

[0009] Furthermore, to facilitate user alignment of the recognition component, an indicator icon corresponding to the position of the recognition component needs to be displayed on the screen component. However, traditional electronic devices typically display the indicator icon by keeping a portion of the screen component constantly lit, which shortens the lifespan of the screen component. To avoid this problem, this application provides a display component for displaying the indicator icon in the electronic device, enabling the electronic device to display the indicator icon even when the screen component is not lit, based on ambient light.

[0010] The display component is located on the side of the recognition component facing outwards, and is positioned opposite to the recognition component. The display component has a first state and a second state, and can switch between the two states. This allows the display component to both display indicator icons and prevent it from blocking reflected light from the biometric features when the recognition component is identifying the user's biometrics. Specifically, in the first state, the display component can display indicator icons under ambient light; that is, it can display the indicator icons by reflecting ambient light, eliminating the need for a portion of the screen component to be constantly illuminated, thus extending the lifespan of the screen component. Furthermore, when biometric identification is required by the recognition component, the display component can switch from the first state to the second state. In the second state, the display component is light-transmitting, allowing reflected light from the user's biometric features to pass through and illuminate the recognition component, enabling the recognition component to identify the biometrics.

[0011] By incorporating a display component into an electronic device, it is possible to display indicator icons under ambient light without requiring the screen component to remain partially lit, thus extending the screen component's lifespan. Furthermore, the display component can also transmit reflected light from the user's biometric features when the identification component needs to perform biometric identification, enabling the identification component to perform biometric identification normally.

[0012] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] In related technologies, electronic devices are equipped with a screen component and a recognition component. The recognition component is used to identify the user's biometric features. In order to make it easier for the user to align with the recognition component, the electronic device often displays an indicator icon corresponding to the recognition component for a long time. In order to make it easier for the user to observe the indicator icon, a part of the screen component is kept lit for a long time to illuminate the indicator icon. However, this will shorten the lifespan of the area of ​​the screen component that is lit for a long time, and thus shorten the lifespan of the display screen of the electronic device.

[0027] The electronic device provided in this application embodiment, in addition to the screen component and the recognition component, also has a display component. The display component can display indicator icons under ambient light, eliminating the need for a portion of the screen component to remain lit for an extended period, thereby extending the lifespan of the screen component and consequently extending the lifespan of the electronic device.

[0028] The electronic device 100 and its control method provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] like Figure 1 As shown, the electronic device 100 includes: a screen assembly 110; an identification component 120 disposed on one side of the screen assembly 110, the identification component 120 being used to identify the user's biometric features; and a display component 130 disposed on the side of the identification component 120 facing the outside, the display component 130 being disposed opposite to the identification component 120. In a first state, the display component 130 can display an indicator icon under ambient light; in a second state, the display component 130 can transmit light to the identification component 120 so that the identification component 120 can identify biometric features.

[0030] Specifically, the electronic device 100 includes a screen assembly 110, an identification component 120, and a display component 130. The screen assembly 110 faces the user and is used to display various screen information to the user. The screen assembly 110 can be an OLED screen. Further, the identification component 120 is located on one side of the screen assembly 110, specifically on the side of the screen assembly 110 facing away from the outside. The identification component 120 is used to identify the user's biometric features. When the user is within a certain range in front of the screen assembly 110, the identification component 120 can receive the reflected light from the user's biometric features. The identification component 120 confirms whether the user's biometric features are preset biometric features based on the reflected light. If the user's biometric features are preset biometric features, the electronic device can perform corresponding functions. The biometric features can be fingerprints, pupils, or other biometric features.

[0031] Furthermore, to facilitate user alignment of the recognition component 120, an indicator icon corresponding to the position of the recognition component 120 needs to be displayed on the screen component 110. However, conventional electronic devices typically display the indicator icon by keeping a portion of the screen component 110 constantly lit, which shortens the lifespan of the screen component 110. To avoid this problem, this application provides a display component 130 for displaying the indicator icon in the electronic device 100, enabling the electronic device 100 to display the indicator icon even when the screen component 110 is not lit, based on ambient light.

[0032] The display component 130 is located on the side of the recognition component 120 facing outwards. The display component 130 is positioned opposite the recognition component 120. The display component 130 has a first state and a second state, and can switch between the two states. This allows the display component 130 to both display indicator icons and prevent it from blocking reflected light from the biometric features when the recognition component 120 is recognizing the user's biometric features. Specifically, when the display component 130 is in the first state, it can display indicator icons under ambient light. That is, the display component 130 can display indicator icons by reflecting ambient light, eliminating the need for a portion of the screen component 110 to be constantly illuminated. This extends the lifespan of the screen component 110. Furthermore, when biometric identification is required through the identification component 120, the display component 130 can switch from the first state to the second state. When the display component 130 is in the second state, the display component 130 is able to transmit light, and the reflected light reflected by the user's biometric features can pass through the display component 130 and illuminate the identification component 120, thereby enabling the identification component 120 to identify biometric features.

[0033] By setting a display component 130 in the electronic device 100, on the one hand, the display component 130 can display indicator icons under ambient light, eliminating the need for the screen component 110 to remain partially lit, thus extending the lifespan of the screen component 110. On the other hand, the display component 130 can also transmit reflected light from the user's biometric features when the recognition component 120 needs to perform biometric recognition, thereby enabling the recognition component 120 to perform biometric recognition normally.

[0034] Furthermore, when the indicator icon is not obscured, the display component 130 enters the first state; when the indicator icon is obscured, the display component 130 enters the second state.

[0035] Specifically, the display component 130 switches between a first state and a second state depending on the occlusion status of the indicator icon. When the indicator icon is not obscured, the display component 130 enters the first state, displaying the indicator icon under ambient light, allowing the user to observe its position on the electronic device 100. Further, when the user needs to perform biometric identification, the user's biometric features are aligned with the indicator icon, at which point the indicator icon is obscured. The display component 130 then enters the second state, where the light reflected from the biometric features passes through the display component 130 and is transmitted to the recognition component 120, which can then identify the biometric features.

[0036] In one possible embodiment, when the recognition component 120 is used for fingerprint recognition, the display component 130 enters a second state when the user's finger covers the indicator icon, and enters a first state when the user's finger is removed from the indicator icon.

[0037] By configuring the display component 130 to enter a first state or a second state depending on the occlusion of the indicator icon, the display component 130 can cooperate with the user to enter different states, thereby realizing the function of displaying the indicator icon or allowing light to pass through.

[0038] like Figure 2 As shown, further, the identification component 120 includes: a plurality of dye particles 131, each dye particle 131 being movable between its respective first and second positions; and a drive member 133 for driving the dye particles 131 to move; wherein, as Figure 5 and Figure 6 As shown, when the dyed particle 131 is in the first position, the display component 130 is in the first state, and the dyed particle 131 can refract ambient light to display indicator icons; as Figure 3 and Figure 4 As shown, when the dyeing particle 131 is in the second position, the display component 130 is in the second state, and the dyeing particle 131 avoids the light rays that enter the recognition component 120.

[0039] Specifically, the identification component 120 includes a plurality of dye particles 131 and a drive member 133. The drive member 133 can drive the dye particles 131 to move between multiple positions to display indicator icons or to cause the dye particles 131 to avoid reflected light from biometric features. The dye particles 131 are capable of moving between their respective first and second positions, and the drive member 133 is used to drive the dye particles 131 to move between their respective first and second positions.

[0040] Among them, such as Figure 5 and Figure 6 As shown, when the colored particle 131 is in the first position, the display component 130 is in the first state. At this time, ambient light can pass through the screen component 110 and illuminate the colored particle 131, which refracts the ambient light. Since the colored particle 131 has color, it can display indicator icons by refracting ambient light.

[0041] Furthermore, such as Figure 3 and Figure 4As shown, when the indicator icon is obscured by the user's biometric features, the dye particles 131 move to a second position, at which point the display component 130 is in a second state. Since the recognition component 120 identifies the user's biometric features by the light reflected from the biometric features, if the light cannot pass through the display component 130, the recognition component 120 cannot properly identify the user's biometric features. Therefore, when the indicator icon is obscured, the driver 133 drives multiple dye particles 131 to move to their respective second positions. At this time, the dye particles 131 avoid the light entering the recognition component 120, enabling the recognition component 120 to properly identify the user's biometric features.

[0042] By setting multiple dye particles 131 and a drive unit 133 for driving the movement of the dye particles 131 in the display component 130, the dye particles 131 can be driven to move to their respective first and second positions by the drive unit 133, thereby realizing the display of indicator icons by the dye particles 131, and when it is necessary to identify the user's biometrics, the dye particles 131 can avoid the light rays entering the identification component 120, so that the identification component 120 can identify the user's biometrics normally.

[0043] like Figure 1 , Figure 4 and Figure 6 As shown, the display assembly 130 further includes: a plurality of accommodating members 132, with a plurality of dyeing particles 131 respectively disposed within the plurality of accommodating members 132, the dyeing particles 131 carrying a charge; the driving member 133 includes: a plurality of first electrode plates 134 disposed outside the accommodating members 132, the plurality of first electrode plates 134 being disposed one-to-one with the plurality of accommodating members 132, the first electrode plates 134 being disposed on the side of the corresponding accommodating member 132 near the screen assembly 110; a plurality of second electrode plates 135 disposed outside the accommodating members 132, the plurality of second electrode plates 135 being disposed one-to-one with the plurality of accommodating members 132, the second electrode plates 135 being disposed on the side of the corresponding accommodating member. The side of the display assembly 132 extends along the thickness direction of the electronic device 100; when the display assembly 130 is in a first state, the charge on the first electrode plate 134 is opposite in nature to the charge on the dyeing particles 131, the second electrode plate 135 is not charged, and the dyeing particles 131 move to the first position close to the first electrode plate 134; when the display assembly 130 is in a second state, the charge on the second electrode plate 135 is opposite in nature to the charge on the dyeing particles 131, the first electrode plate 134 is not charged, and the dyeing particles 131 move to the second position close to the second electrode plate 135.

[0044] Specifically, in order to accommodate the multiple dye particles 131, the display assembly 130 is provided with multiple accommodating members 132, and the multiple dye particles 131 are respectively disposed in the multiple accommodating members 132. The dye particles 131 can move within the corresponding accommodating members 132 under the drive of the driving member 133, and the movement range of the dye particles 131 can be limited by the accommodating members 132.

[0045] Furthermore, the dyed particles 131 are charged, and the driving component 133 includes multiple first electrode plates 134 and multiple second electrode plates 135. The first electrode plates 134 and second electrode plates 135 can switch between charged and uncharged states, and the charge on the first electrode plates 134 and second electrode plates 135 is opposite in polarity to the charge on the dyed particles 131. Thus, the dyed particles 131 can move to a position close to the electrode plates under the attraction of the first electrode plates 134 or second electrode plates 135, thereby enabling the dyed particles 131 to move between their respective first and second positions. The electronic device 100 includes a detection device and a control device. The detection device detects whether an indicator icon is obstructed, and the control device controls the charging state of the first electrode plates 134 and second electrode plates 135. The detection device is electrically connected to the control device, and the control device controls the charging state of the first electrode plates 134 and second electrode plates 135 based on the detection result of the detection device.

[0046] like Figure 5 and Figure 6 As shown, specifically, the first electrode plate 134 is disposed outside the accommodating member 132, and multiple first electrode plates 134 are disposed one-to-one with multiple accommodating members 132. The first electrode plate 134 is disposed on the side of the corresponding accommodating member 132 near the screen assembly 110. When the detection device detects that the indicator icon is not obstructed, the control device controls the first electrode plate 134 to be loaded with a charge of opposite polarity to that loaded by the dyeing particles 131, and controls the second electrode plate 135 to be unloaded, and the display assembly 130 switches to the first state. At this time, the dyeing particles 131 are attracted by the first electrode plate 134 and move to the first position, that is, the dyeing particles 131 move to the side near the screen assembly 110, thereby achieving the technical effect of displaying the indicator icon through the dyeing particles 131.

[0047] like Figure 3 and Figure 4As shown, further, the second electrode plate 135 is disposed outside the accommodating member 132, and multiple second electrode plates 135 are disposed one-to-one with multiple accommodating members 132. The second electrode plates 135 are disposed on the side of the corresponding accommodating member 132, and the second electrode plates 135 extend along the thickness direction of the electronic device 100. When the detection device detects that the indicator icon is obscured by the user's biometrics, the control device controls the second electrode plate 135 to be loaded with a charge of opposite polarity to that loaded by the dye particles 131, and controls the first electrode plate 134 to not be loaded with charge, and the display component 130 switches to the second state. At this time, the dye particles 131 are attracted by the second electrode plate 135 and move to the second position, that is, the dye particles 131 move away from the position near the screen component 110 and move to the side area inside the accommodating member 132. In this way, the dyeing particles 131 avoid the light reflected from the user's biometric features and directed towards the recognition component 120, and the reflected light can smoothly enter the recognition component 120, thereby enabling the recognition component 120 to normally recognize the user's biometric features.

[0048] like Figure 4 and Figure 6 As shown, in one possible embodiment, the dyed particles 131 are loaded with positive charges, while the first electrode plate 134 and the second electrode plate 135 are loaded with negative charges.

[0049] By charging the dyeing particles 131 and configuring the driving element 133 as a plurality of first electrode plates 134 and a plurality of second electrode plates 135, and enabling the first electrode plates 134 and the second electrode plates 135 to switch between charged and uncharged states, the movement of the dyeing particles 131 between a first position and a second position can be driven by the change in the charged state of the first electrode plates 134 and the second electrode plates 135.

[0050] like Figure 5 As shown, the screen assembly 110 further includes an emissive layer 111, which remains off when the display assembly 130 is in the first state.

[0051] Specifically, the screen assembly 110 includes a light-emitting layer 111, which can be either lit or off. When the display assembly 130 is in its first state, since it can display indicator icons under ambient light, the electronic device 100 can display the indicator icons normally without the light-emitting layer emitting light. In this case, the light-emitting layer 111 remains off. This extends the lifespan of the screen assembly 110, and consequently, the lifespan of the electronic device 100.

[0052] like Figure 3As shown, further, when the display component 130 is in the second state, the light-emitting layer 111 is in the light-emitting state, and the identification component 120 receives the reflected light emitted by the light-emitting layer 111 by the user's biometrics, and the identification component 120 identifies the biometrics based on the reflected light.

[0053] Specifically, when the detection device in the electronic device detects that the indicator icon is obstructed by the user's biometric features, the control device controls the light-emitting layer 111 to light up, putting the light-emitting layer 111 into an luminous state. The user's biometric features reflect the light emitted by the light-emitting layer 111, forming reflected light. The reflected light passes through the display component 130 and enters the recognition component 120, which receives the reflected light to identify the biometric features. When the detection device detects that the indicator icon is obstructed by the user's biometric features, the control device controls the second electrode plate 135 to be loaded with a charge opposite to that of the dye particles 131, and controls the first electrode plate 134 to be unloaded. The dye particles 131 move to a second position, at which point the display component 130 is in a second state. Since the dye particles 131 move to the second position to avoid the reflected light, the dye particles 131 do not block the reflected light, thus enabling the recognition component 120 to normally receive the reflected light and achieve normal identification of the biometric features.

[0054] Furthermore, the display component 130 may be disposed within the screen component 110 or outside the screen component 110; when the display component 130 is disposed within the screen component 110, the display component 130 is located on the side of the light-emitting layer 111 facing the outside, or the display component 130 is located on the side of the light-emitting layer 111 away from the outside; when the display component 130 is disposed outside the screen component 110, the display component 130 is located on the side of the screen component 110 facing the recognition component 120.

[0055] Specifically, the display component 130 is used to display indicator icons, and the screen component 110 can transmit light refracted by the display component 130. Therefore, the display component 130 can be placed inside or outside the screen component 110, and the display component 130 can achieve the function of displaying indicator icons.

[0056] When the display component 130 is disposed within the screen component 110, the display component 130 can be disposed either on the side of the light-emitting layer 111 facing the outside or on the side of the light-emitting layer 111 facing away from the outside. When the display component 130 is disposed outside the screen component 110, the display component 130 is located on the side of the screen component 110 facing the recognition component 120, specifically, as shown... Figure 1As shown, the identification component 120 includes multiple support members 121, and the display component can be placed on the support members 121 or disposed between the multiple support members 121.

[0057] like Figure 3 As shown, further, the number of second electrode plates 135 corresponding to any one of the accommodating members 132 is multiple, wherein two of the multiple second electrode plates 135 are arranged opposite to each other, one of the two second electrode plates 135 is loaded with a charge opposite to the charge loaded by the dyeing particles 131, and the other is not loaded with a charge; the electronic device 100 also includes: a first light sensor, disposed between the recognition component 120 and the display component 130, the first light sensor is used to detect the light intensity of the reflected light, and when the light intensity of the reflected light is lower than a first preset value, the charge loading state of at least some of the two second electrode plates 135 corresponding to the accommodating members 132 is switched.

[0058] Specifically, each accommodating member 132 corresponds to multiple second electrode plates 135. Two of the multiple second electrode plates 135 are arranged opposite to each other. One of the two oppositely arranged second electrode plates 135 carries a charge opposite in polarity to the charge carried by the dyeing particles 131, while the other does not carry a charge. In this way, the dyeing particles 131 within the accommodating member 132 can be attracted by the charged second electrode plates 135 and moved to the side closer to the charged second electrode plates 135.

[0059] Furthermore, the electronic device 100 also includes a first light sensor, which is used to detect the intensity of light reflected from the biometric features and directed towards the recognition component 120. Understandably, if the intensity of the reflected light is low, it can easily lead to inaccurate recognition or a slower recognition speed by the recognition component 120. To avoid this problem, this application provides a first light sensor in the electronic device 100 for detecting the intensity of the reflected light. The first light sensor is located between the display component 130 and the recognition component 120, and is electrically connected to the control device in the electronic device. When the first light sensor detects that the intensity of the reflected light is lower than a first preset value, it indicates that less reflected light is passing through the display device. The control device controls at least a portion of the two opposing second electrode plates 135 corresponding to the accommodating member 132 to switch their load states, so that the dye particles 131 in the accommodating member 132 move to the other side. By adjusting the position of some of the dye particles 131, the light transmittance of the display component 130 is increased, allowing the recognition component 120 to receive more reflected light.

[0060] In another possible embodiment, the first light sensor may also be disposed on the identification component 120.

[0061] By setting a first light sensor in the electronic device 100, the light intensity of the light received by the recognition component 120 can be detected by the first light sensor. If the light intensity is low, the position of some dye particles 131 can be changed by switching the load state of the two relatively set second electrode plates 135 corresponding to the partial accommodating member 132, so as to increase the light transmittance of the display component 130, so that the recognition component 120 can receive more reflected light, thereby improving the recognition accuracy and recognition efficiency of the recognition component 120 in recognizing the user's biometrics.

[0062] Furthermore, the electronic device 100 also includes a second light sensor for detecting the intensity of ambient light, wherein when the light intensity is lower than a second preset value, the light-emitting layer 111 displays an indicator icon.

[0063] Specifically, the electronic device 100 also includes a second light sensor for detecting the intensity of ambient light. Understandably, when the electronic device 100 is in a low-light environment, the user may have difficulty observing the indicator icons displayed on the display component 130. In this case, additional light is needed to illuminate the indicator icons. Therefore, when the second light sensor detects that the intensity of the ambient light is lower than a second preset value, the control device controls the light-emitting layer 111 to illuminate. The light emitted by the light-emitting layer 111 illuminates the colored particles 131 in the display component 130. The colored particles 131 refract the light emitted by the light-emitting layer 111, thereby enabling the screen component 110 to display the indicator icons normally.

[0064] Furthermore, the color of the dyed particles 131 is not black. When the display component 130 is in the first state, multiple dyed particles 131 are arranged in sequence to form an indicator icon.

[0065] Specifically, the color of the dye particles 131 is not black. Understandably, when the light-emitting layer 111 of the screen assembly 110 is off, the screen assembly 110 is normally black. If the color of the dye particles 131 is also black, the indicator icon would be difficult to observe. To avoid this problem, this application sets the dye particles 131 to be non-black so that the user can easily observe the indicator icon.

[0066] Furthermore, when the display component 130 is in the first state, a plurality of colored particles 131 are located on the side close to the screen component 110, and the plurality of colored particles 131 are arranged in sequence to form an indicator icon.

[0067] like Figure 7As shown, further, when the screen assembly 110 is in the working state, the light-emitting layer 111 in the screen assembly 110 is lit. Since the display assembly 130 is located below the screen assembly 110, the display assembly 130 will not affect the content displayed on the screen assembly 110, and the screen assembly 110 can work normally. Furthermore, since the display assembly 130 only consumes power when the load state of each electrode plate changes, when the screen assembly 110 is in the working state, it is sufficient to keep the recognition assembly 120 in its original state.

[0068] This embodiment also provides a control method for an electronic device, used in the electronic device described in the first aspect of this application. The electronic device includes a second light sensor for detecting the light intensity of ambient light, and a screen assembly includes a light-emitting layer. The control method includes: controlling the second light sensor to detect the light intensity of ambient light; and controlling the light-emitting layer to operate to display an indicator icon when the light intensity of ambient light is lower than a second preset value.

[0069] like Figure 8 As shown in the figure, one of the flowcharts illustrates a control method for an electronic device according to an embodiment of this application. The control method includes the following steps S102 to S108:

[0070] Step S102: Control the second light sensor to detect the ambient light intensity;

[0071] Step S104: Determine whether the ambient light intensity is lower than the second preset value;

[0072] Step S106: If the ambient light intensity is lower than the second preset value, control the operation of the light-emitting layer to display the indicator icon;

[0073] Step S108: If the ambient light intensity is higher than or equal to the second preset value, control the light-emitting layer to turn off.

[0074] Specifically, the electronic device proposed in this application includes a second light sensor for detecting ambient light intensity, and a screen assembly including a light-emitting layer. When the ambient light intensity is weak (i.e., below a second preset value), the user may have difficulty observing the indicator icons displayed on the display assembly under ambient light. In this case, additional light is needed to illuminate the indicator icons. Therefore, the ambient light intensity can be determined first; if the ambient light intensity is below the second preset value, the light-emitting layer is controlled to operate. Specifically, when the light-emitting layer is operating, it emits light, and the display assembly displays the indicator icons through colored particles contained therein. The light emitted by the light-emitting layer illuminates the colored particles in the display assembly, and the colored particles refract the light emitted by the light-emitting layer, thereby enabling the screen assembly to display the indicator icons. If the ambient light intensity is higher than or equal to the second preset value, the user can observe the indicator icons displayed on the display assembly under ambient light, and at this time, the light-emitting layer is controlled to turn off.

[0075] Understandably, electronic devices are rarely in dark environments (i.e., the ambient light intensity is lower than the second preset value). Therefore, the electronic device provided in this application can still effectively extend the life of the screen assembly and save standby power consumption.

[0076] This embodiment also provides a control method for an electronic device, used in the electronic device described in the first aspect of this application. The display component includes a accommodating member, each accommodating member including a plurality of dye particles movable between their respective first and second positions. The display component includes a plurality of second electrode plates for driving the movement of the dye particles. Two of the plurality of second electrode plates corresponding to any accommodating member are arranged opposite to each other. The electronic device includes a first light sensor for detecting the intensity of reflected light from the user's biometric features reflected into the identification component. The control method includes: controlling one of the two second electrode plates corresponding to any accommodating member to be charged, so that the plurality of dye particles in the accommodating member corresponding to the second electrode plate move to the first position or the second position; controlling the first light sensor to detect the intensity of the reflected light; and when the intensity of the reflected light is lower than a first preset value, switching the charge loading state of at least some of the two second electrode plates corresponding to the accommodating member, so that the plurality of dye particles in the accommodating member move from the first position to the second position, or from the second position to the first position.

[0077] like Figure 9 As shown in the figure, a second schematic flowchart of a control method for an electronic device according to an embodiment of this application is illustrated. The control method includes the following steps S202 to S208:

[0078] Step S202: Control one of the two second electrode plates corresponding to any accommodating element to be charged, so that multiple dyeing particles in the accommodating element corresponding to the second electrode plate move to the first position or the second position;

[0079] Step S204: Control the first light sensor to detect the intensity of the reflected light;

[0080] Step S206: Determine whether the intensity of the reflected light is lower than the first preset value;

[0081] Step S208: If the intensity of the reflected light is lower than the first preset value, then switch the charge load state of the two second electrode plates corresponding to at least part of the accommodating member, so that the multiple dyeing particles in the accommodating member move from the first position to the second position, or from the second position to the first position.

[0082] Step S210: If the intensity of the reflected light is higher than or equal to the first preset value, then the charge load state of the multiple second electrode plates remains unchanged.

[0083] Specifically, the identification component of the electronic device includes multiple accommodating elements, each containing multiple dye particles movable between their respective first and second positions. These dye particles can display indicator icons by reflecting light. When the electronic device needs to identify a user's biometrics, the dye particles need to be moved to appropriate positions so that the reflected light from the user's biometrics can enter the identification component, enabling the component to identify the user's biometrics. If the intensity of the reflected light is low, the identification component may have difficulty identifying the user's biometrics. In this case, it is necessary to control the movement of the dye particles within some of the accommodating elements to increase the light path for the reflected light to pass through.

[0084] Furthermore, to drive the dyed particles in the accommodating element, a plurality of second electrode plates for driving the movement of the dyed particles are provided in the display assembly. Two of the multiple second electrode plates corresponding to any accommodating element are arranged opposite to each other, i.e., the two electrode plates are located on opposite sides of the accommodating element. The two oppositely arranged second electrode plates can switch between a charged and uncharged state. The polarity of the charge on the second electrode plate is opposite to the polarity of the charge on the dyed particles. Therefore, when one of the two oppositely arranged second electrode plates is charged and the other is uncharged, the dyed particles are attracted to the side closer to the charged second electrode plate. If the charged states of the two oppositely arranged second electrode plates are interchanged, the dyed particles will move towards the other second electrode plate. In this way, the dyed particles can be driven to move between their respective first and second positions.

[0085] Furthermore, when driving the dyed particles to move, firstly, one of the two second electrode plates corresponding to any accommodating element is controlled to be charged, while the other is not charged. This allows multiple dyed particles in the accommodating element to move to a first position or a second position. Then, a first light sensor is controlled to detect the intensity of reflected light and determine whether the intensity of reflected light is lower than a first preset value. If the intensity of reflected light is lower than the first preset value, it indicates that the dyed particles are blocking a significant amount of reflected light. Therefore, according to the algorithm pre-stored in the electronic device, at least one of the two second electrode plates corresponding to some of the accommodating elements is controlled to be charged, while the second electrode plate originally charged is decharged. This allows multiple dyed particles in the accommodating element to move from the first position to the second position, or from the second position to the first position, thereby increasing the light transmission channel. If the intensity of reflected light is higher than or equal to the first preset value, it indicates that the dyed particles are not blocking a significant amount of reflected light, and the state of the charged state of the multiple second electrode plates remains unchanged.

[0086] By controlling the charge load state of the second electrode plate according to the intensity of the reflected light, and then controlling the position of the dye particles by whether or not the charge load state of the second electrode plate changes, it is possible to avoid the dye particles causing excessive obstruction of the reflected light, ensure that the intensity of the reflected light can meet the recognition requirements of the recognition component, and ensure that the recognition component can properly recognize the user's biometrics.
