[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] The present application provides a display module that can improve the voice call quality. Please refer to Figure 1 and Figure 2, including: a sensor module 10, a display screen 20, and an FPC 30. The FPC 30 is bonded to the edge of the display screen 20 to avoid the assembly of the FPC 30 affecting the display of the display screen 20. The FPC 30 is electrically connected to the main board in the display screen 20, and the sensor module 10 is electrically connected to the display screen 20 through the FPC 30. The FPC 30 is bent to one side of the display screen 20. The sensor module 10 picks up the voice of the speaker and suppresses the ambient sound, thereby achieving the function of noise reduction, improving the voice call quality in a noisy environment, and enhancing the product competitiveness.

[0024] In one specific embodiment, the specification of the sensor module 10 is V2S200D, and the sensor module 10 is soldered to the FPC 30 through SMT. It should be noted that the V2S200D sensor module 10 is a high-bandwidth, low-power dedicated vibration sensor, which can improve the voice call quality in a noisy environment. This high-performance sensor can selectively pick up the voice of the speaker while suppressing other sounds, thus creating a comfortable and frustration-free voice call experience. The V2S200D has a high signal-to-noise ratio (SNR) of 64.5 dB(A) and a compact package (3.30 mm x 2.30 mm x 0.93 mm). This module has functions such as voice activity detection, impostor rejection, and 50 dB of sound insulation in a noisy environment. The Knowles V2S200D digital voice vibration sensor provides solutions for OEM / ODM that hope to enhance the user experience of their products while adapting to major limitations in industrial design and battery life. After being integrated into the system, the V2S200D emulates a digital microphone with a pulse density modulation (PDM) interface, enabling the sensor module 10 to pick up the voice of the speaker and suppress the ambient sound simultaneously to improve the voice call quality in a noisy environment.

[0025] Furthermore, the size of the sensor module 10 is 3.3 * 2.3 * 0.93 mm.

[0026] Please refer to again Figure 2 , the FPC 30 includes a display FPC 31 and a touch FPC 32. The display FPC 31 and the touch FPC 32 are integrally designed, reducing the number of fixings of the display FPC 31 and the touch FPC 32 and improving the assembly efficiency.

[0027] In one specific embodiment, a component area is provided on the display FPC 31. The component area is used for soldering electronic components, such as capacitors, resistors, etc. After the electronic components are soldered in the component area, the FPC 30 has a weak load-bearing capacity due to its soft texture. A steel sheet is provided on the opposite side of the component area of the display FPC 31. The steel sheet is made of metal steel and has a high hardness, which can support the component area to maintain flatness and improve the reliability. Preferably, a COF driving chip is provided on the FPC 30.

[0028] Furthermore, the thickness of the steel sheet is 0.15 mm.

[0029] Still further, the sensor module 10 is disposed at the edge of the FPC 30 to facilitate better fixing of the sensor module 10 on the display screen 20. Moreover, a reinforcing sheet 11 is provided on the opposite surface of the sensor module 10 on the FPC 30. The reinforcing sheet 11 has a high hardness and can support the sensor module 10 on the FPC 30 to facilitate welding.

[0030] Similarly, in one of the embodiments, a component area is provided on the touch FPC 32, and a steel sheet is provided on the opposite surface of the touch FPC 32 in the component area.

[0031] In one specific embodiment, please refer to Figure 1 , a BTB connector 33 is welded on the FPC 30 to facilitate electrical connection with other electrical components.

[0032] In one specific embodiment, a wearable device is provided, including the foregoing display module that can improve the voice call quality.

[0033] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
