Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 5, an embodiment of the invention discloses an electronic device, which may specifically include a housing 100, a transparent cover 600, a display module, a light emitting element 300, and a fingerprint module 400.
The housing 100 provides an installation base for the components of the electronic device, the housing 100 and the transparent cover plate 600 form an installation space, and the display module, the light emitting member 300 and the fingerprint module 400 are all disposed in the installation space. The display module is used for displaying information such as characters, pictures and videos of the electronic equipment. Fingerprint module 400 is used for discerning user's fingerprint information. The housing 100 includes a frame, the light emitting member 300 is disposed between the frame and the display module, the display module is disposed between the fingerprint module 400 and the transparent cover plate 600, the transparent cover plate 600 has a transparent portion, and the transparent portion can be a part of the transparent area of the transparent cover plate 600. The light emitting member 300 has a light emitting surface opposite to the light transmission portion, so that light emitted from the light emitting member 300 can pass through the light transmission portion. At this time, the light emitting member 300 emits light, which enters the transparent cover 600 through the light-transmitting portion and further exits the transparent cover 600, and is refracted by the user's finger 800, passes through the transparent cover 600 and the display module, and then enters the fingerprint module 400, thereby implementing the fingerprint recognition function. Each layer structure of the display module should have certain luminousness to guarantee that light after the refraction of user's finger 800 can pass each layer structure of the display module. Because fingerprint module 400 is located the below of display module assembly, therefore fingerprint module 400 can not occupy too much display area, and consequently electronic equipment's screen is more than occuping. Optionally, fingerprint module 400 can be photoelectricity fingerprint module. The light emitting member 300 may be an LED lamp, however, the light emitting member 300 may also have other structures, and is not limited herein.
The extending direction of the frame to the display module is a first direction, and the first direction is parallel to the length direction or the width direction of the electronic device. An angle between the first direction and the thickness direction of the light emitting member 300 is less than 90 degrees or equal to 90 degrees. The thickness direction of the light emitting member 300 may be a direction in which the size of the light emitting member is smallest, for example, when the light emitting member 300 has a rectangular parallelepiped structure, the direction in which the size is smallest is the thickness direction.
In the embodiment of the invention, since the thickness direction of the light-emitting member 300 is the minimum dimension direction of the light-emitting member 300, when the electronic device is assembled, the space occupied by the light-emitting member 300 on the frame in the thickness direction is smaller, and the display module can be arranged at a position closer to the frame, so that the width of the black edge at the frame is reduced, the black edge of the electronic device is smaller, and the screen occupation ratio of the electronic device is higher. The size shown as E in fig. 3 is a reduced size of the black border of the electronic device.
In the above embodiment, when the included angle between the thickness direction of the light emitting element 300 and the first direction is greater than 0 degree, the thickness direction of the light emitting element 300 is not parallel to the first direction, and the light emitting element 300 is disposed obliquely; when the included angle between the thickness direction of the light emitting member 300 and the first direction is equal to 90 degrees, the thickness direction of the light emitting member 300 is perpendicular to the first direction. Both of these cases result in a large space occupied by the light emitting member 300 in the frame in the thickness direction. In order to further reduce the space of the frame occupied by the light emitting member 300 in the thickness direction, in another embodiment, the first direction is parallel to the thickness direction of the light emitting member 300, that is, the included angle between the first direction and the thickness direction of the light emitting member 300 is 0 degree, at this time, the length direction of the electronic device is parallel to the thickness direction of the light emitting member 300, the space occupied by the light emitting member 300 in the thickness direction of the frame is smaller, the display module can be arranged at a position closer to the frame, thereby further reducing the width of the black edge at the frame, further making the black edge of the electronic device smaller, and making the screen of the electronic device occupy more than the other. In addition, in the direction perpendicular to the transparent cover plate 600, when the thickness direction of the light emitting member 300 is parallel to the first direction, the projection profile of the light emitting surface is larger, and at this time, more light passes through the transparent portion, so that the light refracted by the finger 800 of the user is increased, and the working performance of the fingerprint module 400 can be improved.
In the above embodiment, the display module may include a main body portion and the flexible circuit board 220, and the main body portion is connected to and electrically connected to the flexible circuit board 220. The main body portion is electrically connected to a main board of the electronic device through the flexible circuit board 220, and the main board of the electronic device controls the main body portion to display through the flexible circuit board 220. At this time, the flexible circuit board 220 is easily interfered with the light emitting member 300, and in order to prevent the interference between the flexible circuit board 220 and the light emitting member 300, a large gap needs to be maintained between the flexible circuit board 220 and the light emitting member 300, and the gap occupies a large display area of the display module, so that the black edge of the electronic device is large, and the screen occupation ratio of the electronic device is low. In order to solve the above problem, in another embodiment, the flexible circuit board 220 may be provided with an avoiding space, and at least a portion of the light emitting element 300 is located in the avoiding space. At this moment, dodge the space and can prevent that light-emitting member 300 and flexible circuit board 220 from taking place to interfere, simultaneously, the at least part of light-emitting member 300 hides in dodging the space for the space that light-emitting member 300 and flexible circuit board 220 wholly occupy is less, thereby makes electronic equipment's black edge less, and then has increased display module's display area, makes electronic equipment's screen account for than higher.
Alternatively, the main body portion may include a first substrate and a second substrate, the light-transmitting cover plate 600, the first substrate, and the second substrate may be stacked in sequence, and the flexible circuit board 220 may be connected to the first substrate or the second substrate. The first substrate and a portion of the flexible circuit board 220 are respectively located at both sides of the second substrate. The first substrate may be provided with a device such as a filter film, and the second substrate may be provided with a device such as a thin film transistor.
As shown in fig. 4, a is a comparison of the length of the light emitting member 300, B is the thickness of the light emitting member 300, C is the length of the light emitting member 300 entering the flexible circuit board 220, D is the minimum mounting distance between the light emitting member 300 and the flexible circuit board 220, L1 is the width of the black edge when the light emitting member 300 is laid horizontally, and L2 is the width of the black edge when the light emitting member 300 is laid vertically, as shown in fig. 4. The horizontal placement is a case where the first direction is parallel to the longitudinal direction of the light emitting member 300, and the vertical placement is a case where the first direction is parallel to the thickness direction of the light emitting member 300. For convenience of calculation, if the lower limit of the visible region passes through the center of the circle corresponding to the bending section of the flexible circuit board 220, then: l1 ═ bend radius + a + D, L2 ═ bend radius + B-C, since a > B, it is clear that Δ L ═ L1-L2 ═ a-B + C + D > 0, indicating that the vertical glowing 300 can significantly reduce the black-edge width.
Further, the light emitting member 300 may be entirely located in the avoiding space, and at this time, the space occupied by the light emitting member 300 and the flexible circuit board 220 as a whole is smaller, so that the black edge of the electronic device is smaller. In the implementation process, it should be ensured that the light emitting surface of the light emitting element 300 is not shielded by the flexible circuit board 220.
In an alternative embodiment, the flexible circuit board 220 may include a first board segment 221, a bending segment 223, and a second board segment 222, where the first board segment 221 and the second board segment 222 are connected by the bending segment 223, the first board segment 221 and the light-transmissive cover plate 600 are located at two sides of the main body, and the bending segment 223 may bend the first board segment 221 below the main body. The second plate section 222 is connected to and electrically connected to the main body section, and an avoiding space may be provided in the bent section 223. In this scheme, dodge the space and can set up on bending section 223, the partial material of bending section 223 was got rid of this moment to make things convenient for bending section 223 to bend.
Optionally, when the flexible circuit board 220 is provided with an avoiding space, at least a part of the light emitting element 300 may be located in the avoiding space. Therefore, when the electronic device is assembled, the arrangement orientation of the light emitting element 300 may be relatively random, that is, the angle between the first direction and the length direction of the light emitting element 300 may be smaller than 90 degrees or equal to 90 degrees, or the angle between the first direction and the width direction of the light emitting element 300 may be smaller than 90 degrees or equal to 90 degrees, and at this time, the light emitting element 300 is relatively flexible to mount.
In the above embodiment, the light emitting member 300 may be electrically connected to a main board or a sub-board of the electronic device through a wire, so that the light emitting member 300 may be controlled to emit light and power may be supplied to the light emitting member 300. At this time, the position electrically connected with the light emitting member 300 needs to be reserved on the main board or the sub board of the electronic device, so that the light emitting member 300 needs to occupy the electrical connection position of the main board or the sub board of the electronic device, and the structural design difficulty of the electronic device is high. In an alternative embodiment, the light emitting member 300 may be electrically connected to the flexible circuit board 220. At this time, the flexible circuit board 220 controls the light emitting member 300 to emit light and provide electric energy for the light emitting member 300, so that the light emitting member 300 does not need to be implemented by a main board or an auxiliary board of the electronic device, and therefore the light emitting member 300 does not occupy an electrical connection position of the main board or the auxiliary board of the electronic device, and the difficulty of structural design of the electronic device is low. Optionally, a first electrical connection terminal may be disposed on the light emitting element 300, and a second electrical connection terminal may be disposed on the flexible circuit board 220, where the first electrical connection terminal is electrically connected to the second electrical connection terminal, so as to electrically connect the flexible circuit board 220 and the light emitting element 300. Or the flexible circuit board 220 and the light emitting member 300 may be electrically connected by a wire, and since the light emitting member 300 is closer to the flexible circuit board 220, the length of the wire is shorter, and thus the manufacturing cost of the electronic device may be reduced.
In the above embodiment, the main body may further include a first polarizer, a second polarizer and an optical adhesive 230, and the transparent cover 600, the first polarizer, the first substrate, the second substrate and the second polarizer are stacked in sequence. The optical performance of the display module can be improved by the first polarizer and the second polarizer, meanwhile, the light-transmitting cover plate 600 and the first polarizer can be connected by the optical cement 230, and the optical cement 230 has good light transmittance, so that the optical performance of the display module cannot be influenced.
In order to prevent the light leakage from the edge region of the light-transmitting portion, which affects the performance of the light-emitting member 300, in an alternative embodiment, the electronic device may further include a first light-shielding portion surrounding the light-transmitting portion. At this time, the first light shielding portion can cover the edge region of the light transmitting portion, thereby preventing stray light from entering the light transmitting portion to affect the light emitting performance of the light emitting member 300.
The present disclosure discloses a package structure of a display module, but other structures may also be adopted, and the present disclosure is not limited thereto. Specifically, the display module may further include a driving chip 260, and the driving chip 260 may be disposed on the main body portion and electrically connected to the main body portion. This kind of scheme can reduce display module's volume to easily display module's batch production.
In the above embodiment, the driving chip 260 may be disposed on the main body portion, and at this time, the driving chip 260 occupies a larger space of the main body portion, so that the display area of the main body portion is reduced, and the screen occupation ratio of the electronic device is lower. In another alternative embodiment, the display module may further include a driving chip 260, the driving chip 260 may be disposed on the flexible circuit board 220, and the driving chip 260 is electrically connected to the flexible circuit board 220. In this scheme, the main body portion does not need to reserve the mounting position of the driving chip 260, so that the display area of the main body portion is large, and therefore the screen occupation ratio of the electronic device is high.
In another alternative embodiment, the number of the light emitting members 300 may be multiple, and a plurality of the light emitting members 300 may be spaced apart, and at least a portion of at least one of the light emitting members 300 is located in the avoiding space.

In this scheme, mount pad 500 is connected with the second face of illuminating part 300, and the third face that sets up dorsad with the light emitting face on the illuminating part 300 can be in unsettled state, therefore illuminating part 300 is when installing into dodging the space, is difficult to take place to interfere with the flexible circuit board to make things convenient for illuminating part 300 to install. Optionally, the mounting seat 500 may be adhered to the bezel, or the mounting seat 500 may be integrally formed with the bezel, and the specific connection manner of the mounting seat 500 and the bezel is not limited herein.
In another alternative embodiment, the size of the light emitting member 300 along the first direction may be a first size, and when the included angle between the thickness direction of the light emitting member 300 and the first direction is greater than 0 degree or equal to 90 degrees, the first size is greater than the thickness of the light emitting member 300; when the included angle between the thickness direction of the light emitting member 300 and the first direction is 0 degree, the first dimension is equal to the thickness of the light emitting member 300. The size of the light emitting member 300 in the thickness direction of the electronic device, which is perpendicular to the light-transmissive cover 600, may be the second size. The size of the light emitting member 300 in the second direction is a third size, the second direction is perpendicular to the first direction and perpendicular to the thickness direction of the electronic device, and the second direction may be the same as the width direction of the electronic device. The first size may be smaller than the second size, and the second size may be smaller than the third size.
