Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] In the manufacturing process of a display panel provided with an opening area, it is generally necessary to perform an opening operation on each film layer by laser after evaporation of each film layer on the panel is completed. However, some film layers are difficult to remove when opening holes. For example, when opening holes on the cathode, it is difficult to remove or pattern the cathode material through the existing process. Due to the low light transmittance of the cathode, if the cathode is kept in ...

Abstract

The invention discloses a mask device, an evaporation method and a display panel. The mask device includes: a first mask and a second mask; the first mask includes a frame shielding part and an evaporation In the opening area, the frame shielding part surrounds the evaporation opening area; when preparing the common film layer of the display substrate, the orthographic projection of the evaporation opening area on the plane where the display substrate is located covers the pixel setting area of ​​the display substrate; the second mask includes an opening The hole shielding part, and at least two carbon fibers extending along the first direction; the carbon fibers are fixedly connected to the hole shielding part, and carry the hole shielding part; the orthographic projection of the hole shielding part on the display substrate covers the preset opening area of ​​the substrate , the orthographic projection of the carbon fiber on the display substrate is located between adjacent sub-pixel openings on the display substrate. The invention provides a mask device, an evaporation method and a display panel to solve the problem that the opening area of ​​the display panel cannot be packaged because the evaporation material is evaporated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask device, an evaporation method and a display panel. 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 a display device with a narrow frame, some holes need to be opened in the screen of the display device, so as to arrange functional devices in the screen opening area of ​​the display device. For example: for a full-screen mobile phone, its 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 normal operation of the front camera. [0004] However, in the manufacturin...
