## Abstract

An organic light-emitting diode (OLED) display panel comprises: a plurality of pixel units arranged in an array, in which each pixel unit includes an organic light-emitting element provided with a first light-emitting surface and a second light-emitting surface; and light shield layers configured to shield at least the first light-emitting surfaces of organic light-emitting elements of a portion of the pixel units. The OLED display panel combines the double-faced organic light-emitting elements and the light shield layers to simply achieve double emission display.

## Claims

### Claim 1

An organic light-emitting diode (OLED) display panel, comprising:
a plurality of pixel units arranged in an array, in which each pixel unit includes an organic light-emitting element provided with a first light-emitting surface and a second light-emitting surface; and
light shield layers configured to shield at least the first light-emitting surfaces of organic light-emitting elements of a portion of the pixel units.

### Claim 2 (depends on 1)

The OLED display panel according to claim 1, wherein the light shield layers include first light shield layers and second light shield layers, in which
the first light shield layers are configured to shield the first light-emitting surfaces of the organic light-emitting elements of the portion of the pixel units, and the second light shield layers are configured to shield the second light-emitting surfaces of organic light-emitting elements of the remaining pixel units.

### Claim 3 (depends on 2)

The OLED display panel according to claim 2, wherein the first light shield layers and the second light shield layers respectively include a plurality of light shield sub-units corresponding to areas where the pixel units are disposed.

### Claim 4 (depends on 3)
