Embodiment 1

[0045] This embodiment provides an optical fingerprint identification (Opitcal Sensitive) module, which solves the problem that the optical fingerprint identification of the current display module terminal is limited to the home button, the integration level is not high, and the distance between the finger and the sensor There are many layers, and the effect of fingerprint recognition is poor.

[0046] The optical fingerprint identification module includes a fingerprint identification module, an optical screening module, and a light source module, wherein:

[0047] The light source module is used to provide a light source to irradiate the fingerprint to be identified;

[0048] The optical screening module is arranged between the light source module and the fingerprint identification module, and collimates the light emitted by the light source module and reflected by external objects (such as fingers) and enters the optical screening module, and the collimated light enters the ...

Embodiment 2

[0070] This embodiment provides an optical fingerprint identification module. The optical fingerprint identification module solves the problem that the optical fingerprint identification of the current display module terminal is limited to the home key. The problem of poor recognition effect. The difference between the optical fingerprint recognition module in this embodiment and the optical fingerprint recognition module in Embodiment 1 lies in that the lamination structure of the light deflection layer and the light filter layer in the light screening module is different.

[0071] exist Figure 3A Among them, the optical fingerprint recognition module is arranged between the first substrate 3 and the second substrate 5 (that is, the first substrate 3 and the second substrate 5 are used as an external support or interface), and the optical screening module is used to form Collimated light to ensure the effect of fingerprint recognition. The light screening module includes a...

Embodiment 3

[0077] This embodiment provides a display panel, which includes the optical fingerprint recognition module in Embodiment 1 or Embodiment 2, and the optical fingerprint recognition module is located in a non-display area of ​​the display panel. By integrating the optical fingerprint identification in the non-display area of ​​the display panel, the display effect of the display area can be guaranteed while the identification accuracy is ensured, and the entire display panel has a compact structure and low cost.

[0078] Wherein, the display panel is a liquid crystal display panel (Liquid Crystal Display, LCD for short) or an organic electroluminescence display panel (Organic Light Emitting Diode, OLED for short). The display panel can integrate an optical fingerprint identification module with either LCD or OLED, which can provide the effect of fingerprint identification on the one hand, and can complete part of the manufacturing process in the same process on the other hand, si...

Abstract

The invention belongs to the technical field of display, and particularly relates to an optical fingerprint recognition module, a display panel and a display device. The optical fingerprint recognition module comprises a fingerprint recognition module, an optical screening module and a light source module, wherein the light source module is used for providing a light source to irradiate a fingerprint to be recognized; the optical screening module is arranged between the light source module and the fingerprint recognition module to carry out collimation on light which is emitted from the light source module and enters the optical screening module via external substance reflection, and collimation light enters the fingerprint recognition module; and the fingerprint recognition module realizes fingerprint recognition according to the received collimation light. The optical fingerprint recognition module has the advantages of low cost, compact structure and good recognition effect. Correspondingly, by use of the display panel, the manufacture technology of a complete machine is simplified, the cost of the complete machine is lowered, the additional value of the display panel is greatly improved, and an optical fingerprint recognition function is added to the display panel except displaying.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an optical fingerprint recognition module, a display panel and a display device. Background technique [0002] In recent years, with the strengthening of people's awareness of their own privacy protection and the severe test of financial security in the field of mobile payment, biometric technology has become extremely popular. Currently, fingerprint recognition is undoubtedly the most widely used biometric technology on mobile phones. Today, fingerprint recognition has become the standard configuration of mid-to-high-end mobile phones, and it is also the most widely used biometric technology on mobile phones. [0003] In the current mobile phone display screen, the optical fingerprint recognition function key of the display module terminal is mostly set on the home key, and the sensor (sensor) is generally silicon-based CMOS (Complementary Metal Oxide Semiconductor...
