Embodiment 1

[0067] In the first embodiment, the display panel 15 may be flexible and easy to bend, that is, the display panel 15 may be a flexible display panel. The display panel 15 includes but is not limited to an organic light emitting diode (organic light emitting diode, OLED) panel, a quantum dot light emitting diode (quantum dot light emitting diode, QLED) panel, and the like. The display panel 15 is used to display images. The light emitted by the display panel 15 can be emitted from the first light-transmitting area 14a, so that the user can see images in the first light-transmitting area 14a.

[0068] Such as image 3 and Figure 4 As shown, the display panel 15 includes a through hole 15c, a non-display area 15b and a display area 15a. The through hole 15 c runs through the display panel 15 , and the axis of the through hole 15 c can be along the thickness direction of the display panel 15 . The shape of the through hole 15c can be similar to that of the second transparent ...

Embodiment 2

[0125] Embodiment 2 provides a method for manufacturing a display panel, which is used to manufacture the above display panel 11 . The manufacturing method may include:

[0126] S31. Manufacturing a TFT backplane;

[0127] S32. Form an organic functional layer on the TFT backplane, so that the organic functional layer includes a first organic layer and a second organic layer, the first organic layer is arranged around the second organic layer, and the first organic layer includes multiple a display unit, the first organic layer is used as a display area of ​​the display panel, the second organic layer does not contain a display unit, and the second organic layer is used as a non-display area of ​​the display panel;

[0128] S33. Opening a surrounding packaging groove on the second organic layer, so that the packaging groove penetrates the second organic layer;

[0129] S34. forming an encapsulation layer on the organic functional layer, so that the encapsulation layer covers...

Abstract

The invention provides a display panel, a display screen comprising the display panel and electronic equipment comprising the display screen. The display panel comprises a thin film transistor backboard, an organic layer and a packaging layer which are stacked in sequence. The display panel is provided with a through hole, and the through hole penetrates through the thin film transistor backboard, the organic layer and the packaging layer; the display panel comprises a non-display area and a display area, the non-display area is arranged around the through hole, and the display area is arranged around the non-display area; the organic layer comprises a first organic layer and a second organic layer, the first organic layer is a part located in the display area, the second organic layer is a part located in the non-display area, the first organic layer comprises a plurality of display units, the second organic layer is provided with a first groove, the first groove penetrates through the second organic layer, and the first groove is arranged around the through hole; the encapsulation layer covers the organic layer and fills the first groove. The invention further provides a manufacturing method of the display panel. The manufacturing method is used for manufacturing the display panel. According to the scheme, the manufacturing cost can be reduced.

Description

technical field [0001] The present application relates to the field of terminal equipment, in particular to a display panel, a manufacturing method thereof, a display screen and electronic equipment. Background technique [0002] The hole-digging screen is a design that can increase the screen-to-body ratio of a mobile phone. The hole-digging screen is to open a through hole (commonly known as "hole-digging" in the industry) on the display panel, and align the front camera with the through-hole. In order to prevent external water and oxygen from entering the display area of ​​the display panel through the through hole, the outer circumference of the through hole is surrounded by an isolation post, which isolates the through hole from the display area of ​​the display panel. However, the structure of the spacer column is complicated, which leads to high manufacturing cost of the display panel. Contents of the invention [0003] The present application provides a display p...
