Referring to fig. 1 and fig. 2, the present application provides a display screen 100, where the display screen 100 includes a first functional layer 10 and a second functional layer 20 that are stacked, and a first medium layer 30 sandwiched between the first functional layer 10 and the second functional layer 20, the first functional layer 10 has a first refractive index, the second functional layer 20 has a second refractive index, and the first medium layer 30 has a first medium refractive index, and the first medium refractive index is between the first refractive index and the second refractive index. It is understood that the display screen 100 is applied to a mobile terminal, which may be a mobile phone, a tablet computer, a notebook computer, or the like. The first functional layer 10, the first dielectric layer 30 and the second dielectric layer 20 transmit light to transmit light signals. The movement enables interaction with the user according to the light signal passing through the display screen 100.
In the present embodiment, the first functional layer 10 and the second functional layer 20 provide different functional functions, respectively. The first functional layer 10 and the second functional layer 20 are both light-transmissive functional layers. The first functional layer 10 completely covers the first dielectric layer 30. The second functional layer 20 completely covers the first dielectric layer 30, and the second functional layer 20 is substantially the same shape as the first functional layer 10. The first functional layer 10 and the second functional layer 20 can still provide a display picture for the display screen 100 in the area beyond the first dielectric layer 30. The first functional layer 10 and the second functional layer 20 do not affect the display of the display screen 100 in the area covering the first medium layer 30. The first functional layer 10 may be a glass substrate and the second functional layer 20 may be a liquid crystal layer adjacent to the glass substrate. The first functional layer 10 may be a polarizing layer and the second functional layer 20 may be a glass substrate adjacent to the polarizing layer. The first functional layer 10 may be a filter layer and the second functional layer 20 may be a polarizing layer adjacent to the filter layer. Of course, the present application is not limited to the above combination of the first functional layer 10 and the second functional layer 20.
In the present embodiment, the first functional layer 10 includes a first upper surface 11 and a first lower surface 12 provided opposite to the first upper surface 11. The first upper surface 11 faces the user and the first lower surface 12 is connected to the first medium layer 30. The second functional layer 20 comprises a second upper surface 21 and a second lower surface 22 arranged opposite to the second upper surface 21. The second upper surface 21 is connected to the first dielectric layer 30, and the second lower surface 22 faces away from the user. When a light ray enters from the second lower surface 22 and exits from the second upper surface 21 to the first medium layer 30, the propagation path of the light ray is refracted, and a first refraction angle a1 is formed. When light is incident into the first functional layer 10 from the first dielectric layer 30 through the first lower surface 12, the light is refracted by the propagation path, and forms a second refraction angle a 2. If the first medium layer 30 is not disposed between the first functional layer 10 and the second functional layer 20, the light is incident from the second functional layer 20 to the first functional layer 10 through the second upper surface 21, the propagation path of the light is refracted, and a refraction angle a0 is formed. The first angle of refraction A1 plus the second angle of refraction A2 is less than the angle of refraction A0. That is, the first dielectric layer 30 is added between the first functional layer 10 and the second functional layer 20, so that the refraction angle of light passing through the first functional layer 10 and the second functional layer 20 is reduced, and the transmission efficiency of light is improved. The first dielectric layer 30 is in close contact with the first functional layer 10, and the first dielectric layer 30 is in close contact with the second functional layer 20, so that the thickness of the display screen 100 is reduced, and the refraction angle of light passing through the display screen 100 is reduced.
Further, referring to fig. 3, the display screen 100 has a display portion 40, and the first medium layer 30 is disposed on the display portion 40.
In the present embodiment, the display panel 100 further includes a non-display unit 50 connected to the display unit 40. The display unit 40 displays a screen.

The length and width of the first functional layer 10 are greater than those of the first dielectric layer 30. The first dielectric layer 30 is opposite to a partial region of the display part 40. The light signal passes through the display portion 40 only in the region corresponding to the first medium layer 30, thereby reducing the cost of the display screen 100. The first dielectric layer 30 is located at the display portion 40 near the short edge 42. The non-display portion 50 includes a first non-display portion 51 and a second non-display portion 52 that connect the two short sides 42, respectively.

The fingerprint identification area 43 is used for being touched by a finger of a user. When light rays sequentially pass through the second functional layer 20, the first dielectric layer 30 and the first functional layer 10 to be emitted to a user finger, the light rays are reflected by the user finger and then sequentially pass through the first functional layer 10, the first dielectric layer 30 and the second functional layer 20 to be incident to one side, away from the user finger, of the display screen 100, so that the user finger feeds the light rays back to a fingerprint module positioned on the other side of the display screen 100, and the fingerprint module identifies fingerprint information of the user. The fingerprint identification area 43 is located on the display portion 40, so that the occupation ratio of the non-display portion 50 can be reduced, the occupation ratio of the display portion 40 on the display screen 100 is increased, the display area screen occupation ratio of the display screen 100 is improved, and the user experience is improved.
Further, referring to fig. 6, the first functional layer 10 is provided with a first groove 13 opposite to the fingerprint identification area 43, and the first medium layer 30 is completely accommodated in the first groove 13.

The first groove 13 is opened on the first lower surface 12, and the opening of the first groove 13 faces the second upper surface 21. The side of the first dielectric layer 30 away from the bottom of the first recess 13 is flush with the first lower surface 12. The first lower surface 12 is attached to the second upper surface 21. The first dielectric layer 30 is contained in the first groove 13, so that the overall thickness of the first functional layer 10, the first dielectric layer 30 and the second functional layer 20 is reduced, that is, the thickness of the display screen 100 is reduced, and the user experience is improved.
In another embodiment, referring to fig. 7, the second functional layer 20 is provided with a second groove 23 opposite to the fingerprint identification area 43, and the first dielectric layer 30 is completely accommodated in the second groove 23.

The surface of the first dielectric layer 30 away from the bottom of the second groove 23 is flush with the second upper surface 21. The second upper surface 21 is attached to the first lower surface 12. The first dielectric layer 30 is contained in the second groove 23, so that the overall thickness of the first functional layer 10, the first dielectric layer 30 and the second functional layer 20 is reduced, that is, the thickness of the display screen 100 is reduced, and the user experience is improved.

In the present embodiment, the third functional layer 60 is a functional layer that can transmit light. The third functional layer 60, the first functional layer 10 and the second functional layer 20 provide different functional roles, respectively. The third functional layer 60 completely covers the second dielectric layer 70. The third functional layer 60 is substantially the same shape as the second functional layer 20. The third functional layer 60 can still provide a display image for the display screen 100 in the area beyond the second medium layer 70. The third functional layer 60 does not affect the image display of the display screen 100 in the area covering the second medium layer 70. If the first functional layer 10 is an upper glass substrate and the second functional layer 20 is close to the liquid crystal layer of the upper glass substrate, the third functional layer 60 may be a lower glass substrate close to the liquid crystal layer. If the first functional layer 10 is a lower polarizing layer and the second functional layer 20 is a lower glass substrate layer adjacent to the lower polarizing layer, the third functional layer 60 may be a liquid crystal layer adjacent to the lower glass substrate layer.

The third upper surface 61 faces the second functional layer 20, and the third upper surface 61 is connected to the second dielectric layer 70. The second dielectric layer 70 is substantially the same shape as the first dielectric layer 30. When light is incident from the third lower surface 62 and exits from the third upper surface 61 to the second medium layer 70, the propagation path of the light is refracted to form a third refraction angle A3, the light is incident to the second functional layer 20 through the second medium layer 70, and the propagation path of the light is refracted to form a fourth refraction angle a 4. If the first dielectric layer 30 is not disposed between the second functional layer 10 and the second functional layer 20, and the second dielectric layer 70 is not disposed between the second functional layer 20 and the third functional layer 60, the light sequentially passes through the third functional layer 60 and the second functional layer 201 and enters the first functional layer 10, the propagation path of the light is refracted, and a refraction angle a0 is formed. The sum of the first, second, third, and fourth refraction angles A1, A2, A3, and A4 is less than the refraction angle A0. That is, the first dielectric layer 30 is added between the first functional layer 10 and the second functional layer 20, so that the refraction angle of light passing through the first functional layer 10, the second functional layer 20 and the third functional layer 60 is reduced, and the transmission efficiency of light is improved.
