DNP develops a new film to reduce blue shift in OLED panels

What They Say

Dai Nippon Printing Co., Ltd. (DNP) said that it has a new film that corrects for a blue shift in OLED panels when viewed from the side by using a microlens structure. The film is said to work from each direction and will lead to sales of $23 million in fiscal 2023.

What We Think

The colour shift from off-axis viewing was one of the challenges that Sony found when it was promoting OLED panels for use in broadcast master monitors. It’s a picky point, but when you are spending 10s of thousands of dollars, you can be picky! There were also challenges in delivering good saturation at higher brightness (colour volume). Because of these things Sony told us a couple of years ago at IBC that it had stopped developing OLED for this application to focus on dual panel. However, the supplier of the dual panels was Panasonic and that company is giving up panel sales. The DNP film would help solve the colour shift problem, but better blue materials are really needed to deal with the colour volume issue. (BR)
