Abstract

An under-screen camera assembly, a backlight module and a display apparatus. The under-screen camera assembly includes: an Organic Light Emitting Diode (OLED) screen, where the OLED screen is provided with an OLED high transmittance region; a first polarizer and a second polarizer both disposed on the OLED high transmittance region, where the second polarizer is stacked on the first polarizer; liquid crystals disposed between the first polarizer and the second polarizer; and a Thin Film Transistor (TFT) driving circuit disposed on the second polarizer and configured for driving the liquid crystals to deflect.

Claims (13)

1 . An under-screen camera assembly, comprising: an Organic Light Emitting Diode (OLED) screen, wherein the OLED screen is provided with an OLED high transmittance region; a first polarizer and a second polarizer both disposed on the OLED high transmittance region, wherein the second polarizer is stacked on the first polarizer; liquid crystals disposed between the first polarizer and the second polarizer; and a Thin Film Transistor (TFT) driving circuit disposed on the second polarizer and configured for driving the liquid crystals to deflect; and

wherein a plurality of liquid crystals are provided, and each of the liquid crystals is connected to the TFT driving circuit and has a different deflection angle from that of another one of the liquid crystals.

2 . The under-screen camera assembly of claim 1 , wherein the under-screen camera assembly further comprises: a camera disposed on one side of the TFT driving circuit and opposite to the liquid crystals.

3 . The under-screen camera assembly of claim 1 , wherein the camera comprises: a camera body; a camera convex lens disposed inside the camera body; and an imaging sensor disposed outside the camera body; and wherein the camera convex lens is disposed opposite to the liquid crystals.

4 . The under-screen camera assembly of claim 1 , wherein, a line on the liquid crystals for driving RGB light-emitting points to light is a transparent Indium Tin Oxide (ITO) material.

5 . The under-screen camera assembly of claim 1 , wherein an area of the OLED high transmittance region is less than that of the first polarizer.

6 . The under-screen camera assembly of claim 5 , wherein the first polarizer, the second polarizer, and the liquid crystals have the same area.

7 . The under-screen camera assembly of claim 6 , wherein the first polarizer and the second polarizer have the same shape.

8 . The under-screen camera assembly of claim 1 , wherein the OLED high transmittance region is disposed under the OLED screen, and when a mobile phone is configured to photograph, light rays emitted by a far-field light source enter an inside of the under-screen camera assembly through the OLED high transmittance region to perform imaging on the camera.

9 . A backlight module, comprising: an under-screen camera assembly, comprising:

an Organic Light Emitting Diode (OLED) screen, wherein the OLED screen is provided with an OLED high transmittance region; a first polarizer and a second polarizer both disposed on the OLED high transmittance region, wherein the second polarizer is stacked on the first polarizer; liquid crystals disposed between the first polarizer and the second polarizer; and a Thin Film Transistor (TFT) driving circuit disposed on the second polarizer and configured for driving the liquid crystals to deflect, and

wherein a plurality of liquid crystals are provided, and each of the liquid crystals is connected to the TFT driving circuit and has a different deflection angle from that of another one of the liquid crystals.

10 . A display device, comprising: the backlight module of claim 9 .
