Embodiment 1

[0046] see figure 1 and figure 2 , figure 1 A schematic view of the light shielding layer provided in the first embodiment of the present invention in the top view direction Figure 1 , figure 2 for figure 1 Schematic diagram of the structure of the light-shielding layer in . The light-shielding layer provided by the embodiment of the present invention includes at least two layers of non-metallic layers arranged in layers, each of the non-metallic layers is provided with an array of metal dots, and the projections of the array of metal dots on each of the non-metallic layers on the same plane are not overlapped ; Each non-metallic layer is respectively provided with a plurality of light-passing places, and the light-passing places on each non-metallic layer at least partially overlap.

[0047] Specifically, the non-metallic layer in this embodiment may be a silicon oxide layer or a silicon nitride layer. The embodiment of the present invention does not limit the materia...

Embodiment 2

[0066] The second embodiment of the present invention provides a display device, the display device includes a display panel 50, a cover plate 40 disposed on the front of the display panel 50, and a fingerprint module 60 disposed on the back of the display panel 50, wherein the display panel 50 includes the above-mentioned shading Floor. Specifically, the light shielding layer provided in the first embodiment is provided in the display panel 50 . like Figure 5 and Image 6 shown, Figure 5 Shown is a schematic structural diagram of the display device when the light-shielding layer includes two non-metallic layers; Image 6 Shown is a schematic structural diagram of the display device when the light shielding layer includes three non-metallic layers. Therefore, the display device provided in the second embodiment of the present invention has the advantages of the light shielding layer provided in the first embodiment, which will not be repeated here.

Abstract

The present invention provides a light-shielding layer and a display device, wherein the light-shielding layer includes at least two layers of non-metallic layers stacked, each non-metallic layer is respectively provided with an array of metal dots, and the array of metal dots on each non-metallic layer is on the same The projections on the plane are not coincident; each non-metallic layer is respectively provided with a plurality of light-through places, and the light-through places on each non-metallic layer are at least partially overlapped. In the light-shielding layer provided by the present invention, the conventional large-area metal layer is replaced by arranging multiple non-metallic layers with metal dot arrays, which effectively reduces stress and additional capacitance, and solves the problems caused by the light-shielding layer in existing display devices. The problem of circuit delay and load increase also solves the problem that the display panel is easily deformed or fragile caused by protrusions caused by excessive stress of the light-shielding layer.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a light shielding layer and a display device. Background technique [0002] In recent years, large-screen display devices have become more and more popular among consumers, and under-screen fingerprint technology can effectively increase the screen-to-body ratio under normal circumstances. The existing under-screen fingerprint recognition usually involves adding an imaging through hole on the display panel, and using the principle of small-hole imaging to present a fingerprint image on the fingerprint sensor, thereby realizing under-screen fingerprint identification. [0003] In the prior art, a display device with an under-screen fingerprint recognition function is usually provided with an opaque metal light-shielding layer under the display panel, and an imaging through hole is arranged on the metal light-shielding layer. If it is too large, additional capacitanc...
