Problems solved by technology

However, the packaging film layer of the existing display panel is made of inorganic materials. When a laser is used to open holes in the packaging film layer of the display panel, the packaging film layer of the display panel will have the risk of cracks, which reduces the finished product of the display device.

Abstract

The invention discloses a mask device, a display panel, a production method of the display panel and a display device and relates to the technical field of display. When trepanning is conducted on a packaging film layer of the display panel, the risk that the packaging film layer cracks is lowered. The mask device comprises one or more types of mask plates. Each mask plate comprises a frame shielding portion. Each frame shielding portion is provided with a material penetration area. Each material penetration area is provided with a trepanning shielding portion. Each frame shielding portion isconnected with the corresponding trepanning shielding portion through a locating shielding portion located in the corresponding material penetration area. The mask device is applied to film formationof a substrate. Under the shadow effect of a film formation process, a film layer is formed by an orthographic projection coverage area, on the substrate, of each locating shielding portion. By meansof the display panel, the packaging film layer is formed through the mask device. The mask device, the display panel, the production method of the display panel and the display device are used for forming the packaging film layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a mask device, a display panel and a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, the frame of the display device is getting narrower and narrower, and even presents a visual effect without a frame, which greatly increases the screen ratio of the display device and improves the user's visual experience. [0003] For display devices with narrow bezels, some functional devices need to open holes in the screen of the display device to ensure normal operation. It is a functional device set in the screen opening area of ​​the display device. For example: for a full-screen mobile phone, the front camera is located in the screen area of ​​the full-screen mobile phone, and a functional hole is opened at the position corresponding to the front camera of the full-screen mobile phone to ensure the nor...
