[0030] The electronic device 100 provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] like Figures 1 to 7 As shown, the electronic device 100 according to an embodiment of the present invention includes a first device body 10, a second device body 20, and a fingerprint module.

[0032] Specifically, the first device body 10 has a first fingerprint recognition area 12. The second device body 20 has a second fingerprint recognition area 22, and the second device body 20 is rotatably connected to the first device body 10. The fingerprint module includes a light guide assembly 31. When the electronic device 100 is in a folded state, the light guide assembly 31 is located in a first position, and the light guide assembly 31 can reflect light from at least one of the first fingerprint recognition area 12 and the second fingerprint recognition area 22 to perform fingerprint recognition through the fingerprint module. When the electronic device 100 is in an unfolded state, the light guide assembly 31 is located in a second position, and the light guide assembly 31 can transmit light from at least one of the first fingerprint recognition area 12 and the second fingerprint recognition area 22 to perform fingerprint recognition through the fingerprint module.

[0033] In other words, see Figures 1 to 4 The electronic device 100 according to an embodiment of the present invention mainly comprises a first device body 10, a second device body 20, and a fingerprint module. Wherein, as... Figure 3As shown, a first fingerprint recognition area 12 is provided on the first device body 10. A second fingerprint recognition area 22 is provided on the second device body 20. The electronic device 100 can be rotatably connected to the first device body 10 via the second device body 20, so that the electronic device 100 can switch between a folded state and an unfolded state, realizing the folding or unfolding of the electronic device 100. Figure 1 and Figure 2 As shown, the fingerprint module includes a light guide assembly 31. When the first device body 10 and the second device body 20 are in a folded state, the light guide assembly 31 can move to a first position. See [reference needed]. Figure 1 and Figure 2 At this time, the light guide component 31 can reflect light from at least one of the first fingerprint recognition area 12 and the second fingerprint recognition area 22 (the light transmission direction is referenced). Figure 1 and Figure 2 (In the direction of the middle arrow). When the electronic device 100 is in a folded state, the user can perform fingerprint recognition by touching either the first fingerprint recognition area 12 or the second fingerprint recognition area 22. In the following embodiments of the present invention, fingerprint unlocking can be performed through this fingerprint recognition.

[0034] When the electronic device 100 is in the unfolded state, such as Figure 4 As shown, the light guide component 31 can be moved to the second position, and the light guide component 31 is capable of transmitting light from at least one of the first fingerprint recognition area 12 and the second fingerprint recognition area 22 (see light transmission direction). Figure 4 (In the direction of the middle arrow). When the electronic device 100 is in the unfolded state, the user can also perform fingerprint recognition by touching the first fingerprint recognition area 12 and the second fingerprint recognition area 22 with their finger 60, realizing multi-mode photoelectric fingerprint recognition and improving the user experience. The electronic device 100 of the present invention can realize multi-mode fingerprint recognition by setting a fingerprint module, which not only reduces the overall cost and improves recognition security, but also effectively saves overall space, which is conducive to the miniaturization and lightweight design of the whole device.

[0035] In this invention, the electronic device 100 can be a foldable screen phone, a foldable tablet computer, or other terminal products. In the following embodiments of this application, a foldable screen phone will be used as an example for specific description.

[0036] Therefore, in the electronic device 100 according to an embodiment of the present invention, a first device body 10 is provided with a first fingerprint recognition area 12, a second device body 20 is provided with a second fingerprint recognition area 22, and the fingerprint module includes a light guide component 31. The light guide component 31 can move between a first position and a second position during the switching between a folded state and an unfolded state of the first device body 10 and the second device body 20. When the light guide component 31 is moved to the first position, it can reflect light from the first fingerprint recognition area 12 and / or the second fingerprint recognition area 22 to enable fingerprint unlocking via the fingerprint module.

[0037] When the light guide component 31 moves to the second position, the light guide component 31 can reflect the light from the first fingerprint recognition area 12 and / or the second fingerprint recognition area 22 to unlock the device with a fingerprint through the fingerprint module. Thus, multi-mode photoelectric fingerprint recognition can be achieved by setting a single fingerprint module, which makes it convenient for users to unlock the device with their fingerprints through either the first fingerprint recognition area 12 or the second fingerprint recognition area 22 in different states of the electronic device 100, greatly improving the user experience.

[0038] According to one embodiment of the present invention, the electronic device 100 further includes: a driving component 40, a portion of which is connected to the first device body 10, and another portion of which is connected to the fingerprint module, the driving component 40 driving the light guide component 31 to be movable between a first position and a second position.

[0039] In other words, such as Figure 1 As shown, the electronic device 100 also includes a driving component 40, wherein a portion of the driving component 40 can be connected to the first device body 10, and another portion of the driving component 40 can be connected to the fingerprint module. The driving component 40 can drive the light guide component 31 to move between a first position and a second position, ensuring that a single fingerprint module can achieve multi-mode photoelectric fingerprint recognition. This allows users to unlock the device using either the first fingerprint recognition area 12 or the second fingerprint recognition area 22 in different states of the electronic device 100, greatly improving the user experience.

[0040] In some specific embodiments of the present invention, the drive assembly 40 includes a bracket 41 and a drive element 42.

[0041] Specifically, the bracket 41 is connected to the first device body 10. One end of the driving member 42 is connected to the bracket 41, and the other end of the driving member 42 is connected to the fingerprint module. The driving member 42 drives the light guide assembly 31 to move between a first position and a second position. The driving member 42 is a screw, with one end passing through the bracket 41 and the other end connected to the light guide assembly 31.

[0042] In other words, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the driving assembly 40 mainly consists of a bracket 41 and a driving component 42. The bracket 41 can be connected to the first device body 10. One end of the driving component 42 can be connected to the bracket 41, and the driving component 42 is movable relative to the bracket 41. The other end of the driving component 42 can be connected to the fingerprint module, and the driving component 42 can drive the light guide assembly 31 to move between a first position and a second position. Optionally, the driving component 42 can be a screw, with one end of the driving component 42 passing through the bracket 41 and the other end connected to the light guide assembly 31.

[0043] The movement of the screw relative to the bracket 41 can drive the light guide component 31 to move between the first position and the second position, ensuring that a single fingerprint module can achieve multi-mode photoelectric fingerprint recognition. This allows users to unlock the electronic device 100 with their fingerprints through either the first fingerprint recognition area 12 or the second fingerprint recognition area 22 in different states, greatly improving the user experience.

[0044] Of course, in this invention, the driving component 40 can be mechanically driven, or driven by a motor or electrical signal. The movement of the driving element 42 can also be achieved by means of a spring or the like. This application does not limit the specific structure of the driving component 40; any structure capable of driving the light guide component 31 to move between the first and second positions should fall within the protection scope of this invention.

[0045] According to one embodiment of the present invention, the first device body 10 includes a first display screen 11, and the second device body 20 includes a second display screen 21. The first display screen 11 is provided with a first fingerprint recognition area 12, and the second display screen 21 is provided with a second fingerprint recognition area 22.

[0046] In other words, such as Figure 1 , Figure 2 and Figure 4 As shown, the first device body 10 includes a first display screen 11, and the second device body 20 includes a second display screen 21. The first display screen 11 can serve as the main screen, and the second display screen 21 can serve as the secondary screen. The first display screen 11 has a first fingerprint recognition area 12, and the second display screen 21 has a second fingerprint recognition area 22. When the first device body 10 and the second device body 20 are in a folded state, the first display screen 11 and the second display screen 21 are located on the outside of the electronic device 100. At this time, the user can unlock the device by touching either the first fingerprint recognition area 12 on the first display screen 11 or the second fingerprint recognition area 22 on the second display screen 21 with their finger 60.

[0047] Similarly, when the first device body 10 and the second device body 20 are in the unfolded state, the first display screen 11 and the second display screen 21 unfold and form a screen. The user can also unlock the device by touching the first fingerprint recognition area 12 on the first display screen 11 or the second fingerprint recognition area 22 on the second display screen 21 with his finger 60.

[0048] According to an embodiment of the present invention, a first display unit 13 is provided in the first device body 10, and the position of the first display unit 13 corresponds to the position of the first fingerprint recognition area 12. A second display unit 23 is provided in the second device body 20, and the position of the second display unit 23 corresponds to the position of the second fingerprint recognition area 22.

[0049] In other words, see Figure 1 , Figure 2 and Figure 4 The first device body 10 has a first display unit 13, which emits light, and its position corresponds to the position of the first fingerprint recognition area 12. The second device body 20 has a second display unit 23, which emits light, and its position corresponds to the position of the second fingerprint recognition area 22. The first display unit 13 mainly consists of a first organic light-emitting panel 131 and a first display pixel 132, and the second display unit 23 mainly consists of a second organic light-emitting panel 231 and a second display pixel 232. The organic light-emitting panel (Active Matrix / Organic Light Emitting Diode, AMOLED) is the core component for realizing the display function of the display unit, and the display pixel is a component of the organic light-emitting panel and is the smallest unit of the display unit, which can emit light under program control. Of course, the specific structure and working principle of the display unit are understandable and achievable by those skilled in the art, and will not be described in detail in this invention.

[0050] According to one embodiment of the present invention, the fingerprint module further includes a first optical device 32, a second optical device 33, and a fingerprint chip 34.

[0051] Specifically, the first optical element 32 corresponds to the positions of the first fingerprint recognition area 12 and the second fingerprint recognition area 22, respectively. A light guide component 31 is disposed within the first optical element 32 and is movable relative to the first optical element 32 between a first position and a second position. The second optical element 33 is located in the light transmission direction of either the first optical element 32 or the light guide component 31. The fingerprint chip 34 is located in the light transmission direction of the second optical element 33.

[0052] In other words, see Figure 1 , Figure 2 and Figure 4 The fingerprint module also includes a first optical element 32, a second optical element 33, and a fingerprint chip 34. The first optical element 32 can correspond to the positions of the first fingerprint recognition area 12 and the second fingerprint recognition area 22, respectively. A light guide assembly 31 is movably mounted within the first optical element 32, and the light guide assembly 31 is movable between a first position and a second position relative to the first optical element 32. The second optical element 33 can be positioned in the light transmission direction of either the first optical element 32 or the light guide assembly 31. The fingerprint chip 34 is positioned in the light transmission direction of the second optical element 33. The first optical element 32 can be a prism or other light-guiding optical element, and the first optical element 32 can change the light path. The second optical element 33 can be a lens or other optical element, such as a collimator, a filter, etc., and the second optical element 33 can also be composed of a combination of two or more optical elements. There can be one or more lenses.

[0053] The fingerprint chip 34, as the core functional component of fingerprint recognition, converts the fingerprint 60 ridges into electrical signals and processes them. Then, it connects electrically with the motherboard processor (Central Processing Unit, CPU) via a flexible printed circuit (FPC) to complete the unlocking process. The active area (AA) on the fingerprint chip 34 is the area used for sensing.

[0054] In this invention, taking the first optical device 32 as a prism as an example, the prism is made of a light-transmitting material and has a certain shape. It is an optical device that can change the direction of light propagation by utilizing the principle of total internal reflection. The lens is made of a light-transmitting material and has a certain shape. It is a light-writing device that can form an image by refraction of light.

[0055] In this invention, the under-display fingerprint recognition design for unlocking the main and secondary screens (first display screen 11 and second display screen 21) divides the AA region of the fingerprint chip 34 into two areas, A and B, for fingerprint recognition on the main screen (first display screen 11) and the secondary screen (second display screen 21), respectively. Figure 7 (As shown). The fingerprint sensors on the main and secondary screens transmit the light reflected from the fingerprint to the fingerprint chip 34 through a movable prism (light guide component 31), realizing single-chip dual-screen 3-fingerprint recognition function.

[0056] It should be noted that, see Figure 7The sensing area (AA area) of the fingerprint chip 34 is divided into area A and area B only logically, not physically. The AA area is still a whole. Structurally, this ensures that the optical paths of the first fingerprint recognition area 12 and the second fingerprint recognition area 22 are aligned with areas A and B of the AA area, respectively.

[0057] In this invention, the prism (first optical device 32) is located below the display screen, the lens (second optical device 33) is located below the prism and corresponds to the light emission position of the prism, and the fingerprint chip 34 is located below the lens. The light guide assembly 31 is connected to the driving component 42, and the movement of the driving component 42 drives the light guide assembly 31 to move at a first position and a second position.

[0058] The electronic device 100 of the present invention can realize fingerprint recognition in three modes. The first mode is that the fingerprint sensor on the main screen (first display screen 11) is used alone, see [link to documentation]. Figure 1 When the device is folded and the front single fingerprint sensor (first fingerprint recognition area 12 collects fingerprints) is working, the light guide component 31 is in the first position, the first display pixel 132 emits light, which is reflected by the first fingerprint recognition area 12 and passes through the lens (second optical device 33) directly into the fingerprint chip 34, and the fingerprint chip 34 works to achieve fingerprint unlocking.

[0059] The second mode allows for separate fingerprint use on the secondary screen (second display 21). See [link / reference] Figure 2 When the device is folded and the single fingerprint sensor on the back (second fingerprint recognition area 22) is working, the light guide component 31 is in the first position. The light emitted by the second display pixel 232 is reflected by the second fingerprint recognition area 22 and then reflected three times by the first optical device 32. The light then passes through the lens (second optical device 33) and enters the fingerprint chip 34, and the fingerprint chip 34 works to achieve fingerprint unlocking.

[0060] The third mode is dual fingerprint recognition on the main screen. See [link / reference] Figure 4 When the device is fully unfolded, the light guide assembly 31 unfolds along with the device and is in the second position. The light emitted from the first fingerprint recognition area 12 on the first display screen 11 passes through the first optical device 32 and enters the second optical device 33. The light emitted from the second fingerprint recognition area 22 on the second display screen 21 is reflected and directly enters the fingerprint chip 34. The A / B areas of the fingerprint chip 34 work simultaneously to determine the fingerprint unlocking.

[0061] This invention achieves dual-screen, three-fingerprint recognition with only one chip, reducing overall device cost and improving recognition security. Simultaneously, a single module enables dual-screen fingerprint recognition, significantly saving space within the device. This facilitates smaller, lighter device design, providing consumers with diverse fingerprint unlocking methods and enhancing user experience and perceived value.

[0062] According to one embodiment of the present invention, the first optical device 32 includes a first lens 321 and a second lens 322.

[0063] Specifically, such as Figure 1 , Figure 2 and Figure 4 , Figure 5 and Figure 6 As shown, the first lens 321 is arranged parallel to and spaced apart from the first device body 10. The second lens 322 is connected to the first lens 321, and the first lens 321 and the second lens 322 cooperate to perform total internal reflection of light at the first fingerprint recognition area 12 or the second fingerprint recognition area 22. The light guide assembly 31 is disposed on the first lens 321, and the light guide assembly 31 is movable relative to the first lens 321 between a first position and a second position, ensuring that a single fingerprint module can achieve multi-mode photoelectric fingerprint recognition. This allows users to unlock the device using either the first fingerprint recognition area 12 or the second fingerprint recognition area 22 in different states of the electronic device 100, greatly improving the user experience.

[0064] In some specific embodiments of the present invention, when the light guide assembly 31 is in a first position relative to the first lens 321, see [reference needed]. Figure 1 , Figure 2 and Figure 5 The light guide component 31 extends at an angle relative to the first lens 321. When unlocking in the second mode, with the device folded and the single fingerprint sensor on the back (second fingerprint recognition area 22) in operation, the light guide component 31 is in the first position. The light emitted by the second display pixel 232 is reflected by the second fingerprint recognition area 22 and then reflected three times by the first optical device 32. The light then passes through the lens (second optical device 33) and enters the fingerprint chip 34, which then operates to achieve fingerprint unlocking.

[0065] When the light guide assembly 31 is in the second position relative to the first lens 321, see Figure 4 and Figure 6 The light guide assembly 31 is attached to the first lens 321. During the third unlocking mode, the device is unfolded, and the light guide assembly 31 unfolds with the device, occupying the second position. The light emitted from the first fingerprint recognition area 12 on the first display screen 11 passes through the first optical device 32 and enters the second optical device 33. The light emitted from the second fingerprint recognition area 22 on the second display screen 21 is reflected and directly enters the fingerprint chip 34. The A / B areas of the fingerprint chip 34 simultaneously perform partitioning and judgment, achieving fingerprint unlocking.

[0066] The cross-section of the second lens 322 can be set to L-shape, and the light guide assembly 31 is installed at the connection position of the first lens 321 and the second lens 322, which facilitates the realization of multi-mode photoelectric fingerprint recognition.

[0067] In this invention, a dual-screen phone is taken as an example, see [link to relevant documentation]. Figure 8 After the phone is powered on, it can be reset to its folded state. When the phone is folded, the driving component 40 moves the light guide component 31 to the first position, and then determines whether to use the main screen fingerprint (first fingerprint recognition area 12). If yes, the main screen single fingerprint is activated. If no, the secondary screen fingerprint is activated. When the phone is unfolded, the driving component 40 moves the light guide component 31 to the second position, and the light guide component 31 is attached to the first lens 321 to ensure that light can be transmitted horizontally along the first lens 321. Then it determines whether dual fingerprint function is needed. If yes, the main screen dual fingerprint is activated to realize the fingerprint function.

[0068] Of course, for those skilled in the art, the electronic device 100 also includes structures such as the upper glass 51 and the lower glass 52, as well as other structures and their working principles, which are understandable and achievable, and will not be described in detail in this invention.

[0069] In summary, according to the electronic device 100 of the present invention, a first fingerprint recognition area 12 is provided on a first device body 10, and a second fingerprint recognition area 22 is provided on a second device body 20. The fingerprint module includes a light guide component 31, which can move between a first position and a second position during the switching between a folded state and an unfolded state of the first device body 10 and the second device body 20. When the light guide component 31 is moved to the first position, it can reflect light from the first fingerprint recognition area 12 and / or the second fingerprint recognition area 22 to unlock the device with a fingerprint. When the light guide component 31 is moved to the second position, it can reflect light from the first fingerprint recognition area 12 and / or the second fingerprint recognition area 22 to unlock the device with a fingerprint. Thus, multi-mode photoelectric fingerprint recognition can be achieved by setting a single fingerprint module, allowing users to unlock the device with their fingerprints using either the first fingerprint recognition area 12 or the second fingerprint recognition area 22 in different states of the electronic device 100, greatly improving the user experience.
