Igzo (indium gallium zinc oxide) screens have higher translucency than standard TFT(thin film transistor) LCDs, meaning they are better at letting light pass through them.
The two companies are at the forefront of this technology which is tipped to replace TFT(thin film transistor) LCDs because OELDs can be made thinner and use less power while delivering a picture that is as good if not better as a TFT.
Rather, it's a reflective display that uses a PNLC (Polymer Networked Liquid Crystal) module for improved brightness, and HR-TFT (high-reflective thin film transistor) technology to add contrast.
