- Key Products/Technologies
- High-precision OLED masks are thin plates crucial for the organic material pattern deposition process in OLED display manufacturing. RIGID OLED masks are utilized for depositing organic patterns on conventional OLED mother glass, while CVD masks are employed in the chemical vapor deposition process for thin-film encapsulation to protect OLED organic materials. These masks are key components for precisely depositing Red, Green, and Blue sub-pixels, determining the resolution of OLED substrates.High-precision OLED masks are thin plates crucial for the organic material pattern deposition process in OLED display manufacturing.
