Advantech U.S., Inc. is developing UHD display masks for the OLED display market.

The mobile display manufacturers are moving to ever higher pixel densities for mobile phone and tablet displays. Over the past few years mobile displays in 5 inch to 7 inch form factor have moved to pixel counts of 1920x1080 (FHD), 2560x1440 (WQHD) and 3840x2160 (UHD) in the same display footprint. Consequently, the demand for high quality pixel and subpixel shadow masks is growing, whereas most shadow mask suppliers are unable to meet the stringent requirements on pixel position and pixel geometry tolerance. The aperture size for UHD masks has moved below 20┬Ám, and Advantech U.S. has developed manufacturing technology for such ultra-precision shadow masks.

Advantech U.S. and partners are providing fully integrated shadow mask solutions to OLED display manufacturers. The entire process chain from mask design, mask sourcing, mask mounting, mask metrology and quality assurance, to mask cleaning and reclaim is covered by Advantech U.S.
