Problems solved by technology

The inventors have found that when using conventional mask support strips for evaporation, there is a problem that the position accuracy of the irregular-shaped area formed after evaporation is not high, which may cause the under-screen device that should be located under the abnormal-shaped area to be incomplete. Located under the shaped area, thereby affecting the performance of electronic devices using the display panel

Abstract

The embodiment of the invention provides a mask supporting piece and a mask structure, and relates to the technical field of display. According to the mask supporting piece, by arranging a balance part, the balance weights on two sides of the mask supporting piece in the extending direction of the mask supporting piece are balanced, so that in the net stretching process of the mask supporting piece, the situation that the mask supporting piece deviates or even turns over due to the fact that the balance weights on two sides of the extending direction of the mask supporting piece are not uniform is avoided, and therefore, it can be ensured that a display panel obtained through evaporation by adopting the mask structure comprising the mask supporting piece has a high-precision special-shaped area. In addition, poor evaporation (such as color mixing of organic light-emitting materials of adjacent sub-pixels) caused by a shadow effect on the periphery of the special-shaped area due to deviation or overturning of the mask supporting piece can be avoided, and the display quality of the display panel is ensured.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a mask support and a mask structure. Background technique [0002] Display panels (for example, OLED display panels) often reserve special-shaped areas (for example, notch areas or water drop areas, etc.) for setting off-screen devices (for example, front-facing cameras, face recognition sensors, distance sensors, etc.). In the manufacturing process of such a display panel, when the organic luminescent material layer of a pixel is evaporated, it is necessary to design a shielding portion for shielding the organic luminescent material layer on the mask support bar to form a special-shaped area on the display panel. The inventors have found that when using conventional mask support strips for evaporation, there is a problem that the position accuracy of the irregular-shaped area formed after evaporation is not high, which may cause the under-screen device that should be...
