FIELD OF INVENTION

The present disclosure relates to the field of display technologies, and more particularly to an organic light emitting diode (OLED) display panel, a manufacturing method thereof, and an intelligent terminal.

BACKGROUND OF INVENTION

With development of full display technology, an organic light-emitting diode (OLED) display screen is required for a higher screen-to-body ratio. In existing technologies, a camera module of an OLED display is disposed in a camera area, thereby an O-cut area and a U-cut area need be designed in the camera area. However, the O-cut area and the U-cut area occupy a large space in the camera area, which leads to a wider non-display area of the OLED display screen and a smaller screen-to-body ratio of the OLED display screen.

The OLED display panel includes an electronic component area configured to position an electronic component and a sub-pixel area correspondingly disposed above the electronic component area. The sub-pixel area includes a plurality of sub-pixels, and a first hole disposed on one of the sub-pixels is filled with a transparent material.

In an embodiment of the present disclosure, the OLED display panel further includes a thin film transistor layer disposed between the electronic component area and the sub-pixel area. A second hole disposed on the thin film transistor layer and corresponding to the electronic component area is filled with the transparent material.

In an embodiment of the present disclosure, the OLED display panel further includes a substrate that includes the electronic component area. The electronic component area is a groove disposed on a side of the substrate away from the sub-pixel area.

In an embodiment of the present disclosure, an orthographic projection of the first hole on the substrate is within the groove.

In an embodiment of the present disclosure, the thin film transistor layer includes a buffer layer, an active layer, an insulating interlayer, a gate, a gate insulating layer, a source, a drain, and a planarization layer sequentially stacked on the substrate. The second hole extends through the buffer layer, the active layer, the insulating interlayer, the gate, the gate insulating layer, the source, the drain, and the planarization layer, or the second hole extends through the active layer, the insulating interlayer, the gate, the gate insulating layer, the source, the drain, and the planarization layer.

In an embodiment of the present disclosure, the transparent material is selected from siloxane and colorless polyimide.

In an embodiment of the present disclosure, the OLED display panel further includes a display area disposed outside the electronic component area. Pixel density in the sub-pixel area correspondingly disposed above the electronic component area is less than pixel density in the display area.

An embodiment of the present disclosure further provides a method of manufacturing an OLED display panel. The method includes: disposing an electronic component area and a sub-pixel area correspondingly, wherein the electronic component area is configured to position an electronic component, and the sub-pixel area includes a plurality of sub-pixels; and disposing a first hole on one of the sub-pixels and filling a transparent material in the first hole.

A second hole disposed on the thin film transistor layer and corresponding to the electronic component area is filled with the transparent material.

In an embodiment of the present disclosure, the OLED display panel further includes a substrate that includes the electronic component area. The electronic component area is a groove disposed on a side of the substrate away from the sub-pixel area.

In an embodiment of the present disclosure, an orthographic projection of the first hole on the substrate is within the groove.

In an embodiment of the present disclosure, the thin film transistor layer includes a buffer layer, an active layer, an insulating interlayer, a gate, a gate insulating layer, a source, a drain, and a planarization layer sequentially stacked on the substrate. The second hole extends through the buffer layer, the active layer, the insulating interlayer, the gate, the gate insulating layer, the source, the drain, and the planarization layer, or the second hole extends through the active layer, the insulating interlayer, the gate, the gate insulating layer, the source, the drain, and the planarization layer.
