[0033] As shown in Figure 1 The present application relates to a fingerprint module, a display screen and an electronic device. The fingerprint module comprises: a circuit board 10; the circuit board 10 refers to connecting electronic components together through conductive circuits to realize circuit functions; it serves as the skeleton of the electronic device, carrying all electronic components and circuit connections.

[0034] Preferably, the circuit board 10 is a flexible circuit board 10 or a printed circuit board 10. It can meet the needs of various use scenarios.

[0035] The support component 20 is provided on the circuit board 10; the support component 20 is an auxiliary component for supporting the entire system structure, which can realize good fixing and assembly effect, thereby ensuring the stable connection effect between components.

[0036] The PMOLED module 30 is arranged on the support component 20 away from the circuit board 10 and opposite to the circuit board 10. The PMOLED module 30 is the core component of the display system and is responsible for displaying relevant information. At the same time, by arranging the PMOLED module 30 above the support component 20, a frame structure with a hollow containing cavity can be formed with the circuit board 10, thereby achieving a good component assembly effect.

[0037] The lighting component 40 is electrically connected with the circuit board 10 and located below the PMOLED module 30. A good lighting effect can be achieved to provide a light source, thereby ensuring accurate fingerprint recognition. At the same time, a good electrical connection effect between components can be achieved to ensure good electrical signal transmission effect.

[0038] The fingerprint recognition camera module 50 is electrically connected with the PMOLED module 30 and the circuit board 10. A good shooting and fingerprint recognition effect can be achieved to ensure a good under-screen fingerprint recognition effect.

[0039] Specifically, the fingerprint recognition camera module 50 is a key component of the entire system, responsible for capturing fingerprint images and comparing them.

[0040] The working principle is as follows: electrical connection and data transmission: the fingerprint recognition camera module 50 is electrically connected with the PMOLED module 30 and the circuit board 10. It can not only obtain power from the circuit board 10, but also work cooperatively with the PMOLED module 30 and can also be dynamically adjusted according to the display content.

[0041] Image acquisition and recognition: the camera module will collect fingerprint images and identify them through algorithm comparison, thereby performing unlocking or locking actions. If necessary, the fingerprint camera module can make corresponding adjustments through the information or feedback provided by the PMOLED module 30.

[0042] Among them, the lighting component 40 is at least partially arranged directly below the PMOLED module 30 to provide a light source. The lighting component 40 provides a light source to illuminate the fingerprint recognition area so that the fingerprint recognition camera module 50 can more clearly capture the details of the fingerprint.

[0043] In low-light environments, the lighting component 40 can help improve the accuracy of fingerprint recognition and ensure that the camera module can capture clear fingerprint images.

[0044] By arranging the lighting component 40 directly below the PMOLED module 30, the light source can uniformly illuminate the fingerprint area, avoiding problems such as shadows or uneven brightness.

[0045] From the above description, it can be seen that the present application achieves the following technical effects:

[0046] In the embodiment of the present application, by adding the lighting component 40, the lighting component 40 is at least partially arranged below the PMOLED module 30 to provide a light source, so as to achieve the purpose of turning on the under-screen light source when the fingerprint recognition closes the screen display, thereby realizing the technical effect of under-screen fingerprint recognition, and further solving the technical problem that in the related art, the fingerprint pressed on the screen is photographed by the camera placed under the screen, and then the fingerprint recognition is performed through the algorithm, but since the camera and the PMOLED screen driving principle are both line-by-line scanning, and the scanning frequencies of the two are difficult to be consistent or in a multiple relationship, the photo taken by the camera will have stripes, so there is a technical problem of fingerprint unrecognizable or misrecognition.

[0047] Further, the PMOLED module 30 comprises a PMOLED screen body 301 and an identification unit 302, the identification unit 302 is arranged on the PMOLED screen body 301 and located above the lighting component 40. It can be understood that the PMOLED screen body 301 is mainly used for displaying content, as a basic component of the display module.

[0048] The identification unit 302 is arranged on the PMOLED screen body 301 and located above the lighting component 40, which is responsible for the function of touch recognition or fingerprint collection.

[0049] Further, the identification unit 302 is a touch point, and a plurality of annular fingerprint marks are arranged on the touch point. It can be understood that the touch point is responsible for the area of touch or fingerprint input, which can usually sense the touch of the fingerprint or finger.

[0050] The annular fingerprint mark refers to a fingerprint recognition area formed by a plurality of marks, and different areas of the fingerprint correspond to the marks, which helps to improve the recognition accuracy of the fingerprint and can accurately locate the fingerprint image in the touch screen, especially at different finger positions and touch angles.

[0051] By having a touch point on one side of the PMOLED screen surface, a signal can be transmitted to the fingerprint camera without affecting the screen transmittance.

[0052] Further, the PMOLED screen body 301 is a high-transmittance transparent screen. It can be understood that by using a high-transmittance transparent screen, more light can be transmitted, which facilitates the fingerprint camera to take a fingerprint through the screen.

[0053] Improve the recognition effect: by optimizing the light transmittance of the PMOLED screen body 301, the interference of the display screen on the fingerprint recognition process can be reduced, thereby improving the accuracy of recognition.

[0054] Further, the lighting component 40 is a plurality of LED lights, the plurality of LED lights are arranged around the fingerprint recognition camera module 50, and at least part of the LED lights are located directly below the recognition unit 302. It can be understood that the light source is uniformly irradiated to the fingerprint area to avoid shadows or light spots, which affects the recognition effect; at the same time, by arranging the LED light under the screen, the light source can be provided when the fingerprint camera takes a picture, so that the picture is clearer.

[0055] Further, the PMOLED screen body 301 is further provided with a light-blocking material layer, a plurality of through holes are arranged on the light-blocking material layer, and at least part of the light-blocking material layer is matched with the position of the through hole. It can be understood that the light-blocking material layer is mainly used to reduce the reflection light or stray light of the PMOLED screen body 301, prevent the display light of the screen body from interfering with the fingerprint recognition process, and ensure that the camera can focus on the recognition area; the through hole can guide the light to pass through the light-blocking layer, and the light guide piece further guides and distributes the light, so that the light source is more uniformly irradiated to the fingerprint area, and the light illumination effect of recognition is improved.

[0056] Further, the light-blocking material layer comprises a linear polarizer and a quarter-wave plate.

[0057] One side of the linear polarizer is arranged towards the non-display surface of the PMOLED screen body 301, and the other side of the linear polarizer is arranged towards the quarter-wave plate.

[0058] One side of the quarter-wave plate is arranged towards the linear polarizer, and the other side of the quarter-wave plate is arranged towards the fingerprint recognition camera module 50. It can be understood that the linear polarizer is used to polarize light, and reduce the interference of the reflection light from the display screen on the fingerprint recognition process.

[0059] The quarter-wave plate is mainly used to control the phase of light, and further optimize the propagation and guidance of light.

[0060] Further, the PMOLED screen body 301 is further provided with an anti-reflection coating on the side away from the recognition unit 302. It can be understood that by arranging the anti-reflection coating, the reflection loss of light can be reduced, and more light can penetrate the PMOLED screen body 301, while the fingerprint recognition process is not affected; at the same time, the overall light transmission performance of the screen is improved, and the camera module can capture the fingerprint image more clearly, thereby reducing the interference of the screen reflection on the image.

[0061] Further, the PMOLED screen body 301 and the light-blocking material layer are further provided with an anti-reflection coating. It can be understood that good anti-reflection effect can be achieved.

[0062] The application also relates to a display screen comprising the fingerprint module.

[0063] The application also relates to an electronic device comprising the display screen.
