Abstract

The embodiment of the invention discloses a bonding method of a display device and a fingerprint module. The display device comprises a display panel, a fingerprint module and a functional flexible circuit board FPC. A colloidal film is attached to the side of the display panel away from the light emitting surface, and an opening area is arranged in the colloidal film. A functional FPC is attachedto the side of the display panel away from the light emitting surface through a scattering film. The fingerprint module is arranged on the side of the functional FPC close to the display panel, and the fingerprint module is embedded in the opening area of the gelatin film through the functional FPC. The embodiment of the invention solves the problem of high cost of the display device due to the need of additional special FPC carrier and the need of using a special machine to execute additional device mounting process in the integration and bonding mode of the fingerprint module in the prior display device.

Description

technical field [0001] The present application relates to but is not limited to the fields of display technology and fingerprint technology, and especially refers to a bonding method of a display device and a fingerprint module. Background technique [0002] As a commonly used means of identification, fingerprint recognition technology has become the standard configuration of mobile terminal equipment such as mobile phones. With the development of full-screen technology, the fingerprint recognition module of display devices such as mobile phones is gradually transferred to the back of the display screen to simultaneously realize fingerprint recognition under the screen and full-screen display. [0003] In the prior art, the way of integrating and bonding the fingerprint identification module in the display screen is usually: firstly, the chip, sensor, connector and its auxiliary components of the fingerprint module are fabricated on a dedicated flexible printed circuit (FPC ...
