Abstract

The present disclosure proposes a net stretching machine. The net stretching machine includes a body, and the body has a bearing surface. Wherein, the stretching net machine also includes a plurality of grooves and a plurality of air floating balls. A plurality of grooves are opened on the bearing surface of the body, air holes are opened at the bottom of the grooves, and the grooves communicate with the air floating mechanism through the air holes. A plurality of air floating balls are accommodated in the plurality of grooves respectively, and a part of the air floating balls is exposed on the bearing surface through the notches of the grooves. Wherein, the cavity size of the groove is larger than the diameter of the air float ball; wherein, the mask frame is carried on a plurality of air float balls, and the air float ball is configured to float when the air float mechanism blows air into the groove through the air hole .

Description

technical field [0001] The invention relates to an OLED device manufacturing process, in particular to a stretching machine. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology has gradually become the main development direction of flat panel display technology due to its characteristics of light and thin devices, low power consumption, high contrast ratio, high color gamut and flexible display. OLED display technology mainly includes PMOLED (Passive matrix OLED, passive matrix organic electroluminescent diode) display technology and AMOLED (Active matrix OLED, active matrix organic electroluminescent diode) display technology. [0003] Among them, the implementation methods of AMOLED display technology include "LTPS backplane + fine metal mask (FMM Mask)" and "Oxide backplane + WOLED + color film". The former is mainly used in small-sized panels, such as the display design of mobile phones and mobile products, ...
