Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application 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 application.
Embodiments of the present application provide a display panel, which will be described in detail below.
Referring to fig. 1 to fig. 3, a display panel 100 according to an embodiment of the present disclosure may include a fingerprint identification module 200, where the fingerprint identification module 200 is disposed inside the display panel 100. The fingerprint identification module 200 may include an optical sensing unit 201 and an optical channel array 202. Wherein the optical channel array 202 is located on the optical sensing unit 201. The optical channel array 202 may be used for filtering the interference light in the light reflected by the fingerprint 300, so as to collimate the received light, and output the collimated light to the optical sensing unit 201. The optical sensing unit 201 may be configured to generate a fingerprint recognition signal according to the received collimated light.
It should be noted that the incident light with the angle less than or equal to the predetermined angle is the effective fingerprint signal light with a larger vertical incident component in the embodiment, and when the incident light with the angle less than or equal to the predetermined angle is incident, the optical channel array 202 has high transmittance and high diffraction efficiency, so that the signal with higher energy can be received. That is, the light tunnel array 202 can be used to transmit incident light with an emission angle smaller than or equal to a predetermined angle. In addition, the incident light larger than the preset angle is the invalid fingerprint signal light having a smaller vertical incident component in the present embodiment. When incident light greater than a predetermined angle is incident, the light channel array 202 may be configured to absorb incident light having an incident angle greater than the predetermined angle, thereby receiving a lower energy signal. Specifically, since the incident light larger than the predetermined angle has a smaller vertical incident component, the intensity of the bright pattern generated by the incident light larger than the predetermined angle is weaker than the intensity of the bright pattern generated by the incident light smaller than or equal to the predetermined angle, that is, the intensity of the invalid fingerprint signal light larger than the predetermined angle is weaker than the intensity of the valid fingerprint signal light smaller than or equal to the predetermined angle, so that the fingerprint information can be effectively identified. The predetermined angle is a boundary angle of the invalid fingerprint signal light and the valid fingerprint signal light in the optical channel array 202, which may be specifically determined by the optical channel array 202.
Referring to fig. 4-6, the light channel array 202 provided in the present embodiment may include at least two light filtering units 202'. The light filtering unit 202' may include light absorbing layers 2021 and light channels 2022 between the light absorbing layers 2021. It is understood that at least two light filtering units 202' are arranged in a two-dimensional array.
The light absorbing layer 2021 may be made of a light absorbing material. As can be seen from fig. 4 or fig. 5, the light absorbing layer 2021 is filled between the light channels 2022 to form an integral body. That is, each light channel 2022 and the light absorbing layer 2021 form an integrated structure. It should be noted that, in the embodiment of the present application, the combination manner of the light absorbing layer 2021 and each light channel 2022 is not limited at all, as long as the light absorbing layer 2021 can cover the sidewall of each light channel 2022 to absorb the interference light. The light absorbing material can be black glass or other materials with high absorption and low transmittance to light.
The material filled in the optical channel 2022 may be a high light transmittance material (such as air, cryolite, magnesium fluoride, silicon dioxide, aluminum oxide, zinc sulfide, etc.). Preferably, the material filled in the optical channel 2022 may be air. It should be noted that, when the material filled in the optical channel 2022 is air, the thickness of the optical channel array 202 can be reduced by at least one third. It should be noted that the plurality of optical channels 2022 are arranged in an array. Wherein, the sidewall of each light channel 2022 is covered by the light absorbing layer 2021.
In the embodiment of the present application, the light channel 2022 is vertically disposed on the optical sensing unit 201, when the light is reflected by the fingerprint 300, most of the light reflected by the fingerprint 300 is vertically incident into the light channel 2022, but a small part of the light is emitted outward and obliquely incident into the light channel 2022 during the transmission process; the light reflected by the non-fingerprint 300 also enters the light channel 2022 obliquely. When the light reflected by the fingerprint 300 passes through the light channel 2022, since the light channel 2022 is perpendicular to the optical sensing unit and the light absorbing layer 2021 is coated outside the light channel 2022, the light channel 2022 only allows the light reflected by the fingerprint 300 to pass through the light channel, and absorbs the light mixed in the light of the fingerprint 300 and having an oblique angle with respect to the light channel 2022. That is, the array of light channels 202 has the effect of collimating the received light. Therefore, the optical sensing unit 201 can only receive light near perpendicular to the light channel array 202.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. In the present embodiment, the display panel 100 may be an Organic Light-Emitting Diode (OLED) display panel.

It should be noted that, in this case, the fingerprint identification unit 200 may be located on a side of the array substrate 10 away from the light emitting layer 20. Specifically, the light channel array 202 may be located on a side of the array substrate 10 away from the light-emitting layer 20. The optical sensing unit 201 may be located on a side of the light channel array 202 away from the array substrate 10.
Referring to fig. 2, fig. 2 is another schematic structural diagram of a display panel according to an embodiment of the present disclosure. In this embodiment, the Display panel 100 may be a Liquid Crystal Display (LCD) panel.
The liquid crystal display panel may include an array substrate 11, a color film substrate 21, a liquid crystal layer 31, an upper polarizing layer 41, a lower polarizing layer 51, and a backlight module 61.

The upper polarizing layer 41 is disposed on the color filter substrate 21. The lower polarizer 51 is disposed on a side of the array substrate 11 away from the color filter substrate 21. The backlight module 61 may be disposed on a side of the lower polarizing layer 51 away from the array substrate 11.
The backlight module 61 may include a back plate 611 and an optical assembly 612. The optical assembly 612 is disposed on a side of the lower polarizing layer 51 away from the array substrate 21. The back plate 611 is disposed on a side of the optical assembly 612 away from the lower polarizing layer 51. It is understood that the optical assembly 612 may include a diffusion sheet, a light guide plate, a prism sheet, and the like.
In some embodiments, the optical sensing unit 201 may be located between the array substrate 11 and the liquid crystal layer 31. The optical channel array 202 may be located between the color filter substrate 21 and the upper polarizing layer 41. At this time, the optical sensing unit 201 may include a plurality of optical sensing sub-units 2011. It should be noted that the optical sensor sub-units 2011 correspond to the optical channels 2022 of the optical channel array 202 one to one.
In some embodiments, the fingerprint recognition module 200 may be located inside the backlight module 61. Specifically, as shown in fig. 3, the fingerprint recognition module 200 may be located between the back plate 611 and the optical assembly 612. Specifically, the optical sensing unit 201 may be located on a side of the back plate 611 close to the optical assembly 612. The array of light channels 202 may be located on a side of the optical assembly 612 proximate the back plate 611. In this case, the backlight module 61 may be a side-in type backlight module.
In some embodiments, the backlight module 61 may further include an infrared light generator 62 and a filling layer 63.
The infrared light generator 62 may be disposed on the back plate 611 and surround the fingerprint recognition module 200. This infrared light generator 62 can be used for launching the infrared light, and this infrared light jets out from display panel 100 and takes place the reflection after 300 contacts with the fingerprint, and on the effective fingerprint signal infrared light of 300 reflections of fingerprint can act on fingerprint identification module 200, this fingerprint identification module 200 can produce corresponding fingerprint identification signal according to effective fingerprint signal infrared light.
The filling layer 63 may be disposed on the back plate 611 and surround the infrared light generator 62. The filler layer 63 may support the back plate 611 and the optical assembly 612.
In summary, the objective of the present application is not to completely block the invalid fingerprint signal light source, but to filter the interference light in the light reflected by the fingerprint 300 through the arrangement of the optical channel array 202, so that the received light is collimated, thereby improving the accuracy of the acquired fingerprint identification signal. Since the light channel array 202 can collimate the received light, the incident angle of the disturbance light can be reduced to some extent, so that the thickness of the light channel array 202 is reduced. Moreover, since the material filled in the light channels 2022 of the light channel array 202 is air in the present application, the thickness of the light channel array 202 can be reduced by at least one third, thereby reducing the thickness of the display panel 100.
