Prexision 800 Evo

There has been a fast technological development within the display industry, the pixels getting smaller and smaller and trend towards more complex display such as AMOLED. This trend requires more complicated pixel designs and more pattterns inside pixel. Prexision 800 Evo is designed to support efficient production of the most advanced display such as high resolution AMOLED displays for flagship smartphones. With 25% increase in resolution Prexision 800 Evo will deliver superior benefits to mask makers since the significant improvement of CD Uniformity and better pattern fidelity can be achieved without jeopardizing productivity by setting a new resolution standard.

Prexision 80 Evo

The Prexision 80 Evo is for photomasks for up to Generation-8 size panels for the ever-increasing pixel density of smartphone and tablet displays. For the highest resolution AMOLED and LCD displays, the Prexision 80 Evo gives unsurpassed photomask quality. With 70% better global and local placement performance, our Prexision 80 Evo is taking photomask quality to new heights.

Prexision 8 Evo and Prexision 10

Prexision 8 Evo and Prexision 10 are the best fit for the volume production of advanced TFT-LCD photomasks.
