DNP Develops Film That Corrects Blue Tint of Organic El Panels When Viewed from an Angle
Tokyo, Japan, Nov. 13, Dai Nippon Printing Co., Ltd. (DNP, TOKYO: 7912) has developed a new film that corrects the blue tint seen in organic electroluminescent (EL) panels when viewing devices from an angle.
Organic EL panels are being increasingly employed in smartphones, tablets, computers and televisions, but while exhibiting high contrast and fast response speed, tend to develop a color shift, appearing blue, when viewed from an angle.
Going forward, solution needs will become more acute in line with the increased size of TV screens and the widespread use of foldable smartphones and in-vehicle displays.
DNP’s unique solution leverages proprietary fine patterning technology to create a film capable of correcting for this blue tint and reproducing vivid colors even when viewed from an angle.
The new film will be marketed as “Blue Shift Control Film.”
DNP will provide this film to panel makers, aiming for annual sales of JPY 2.4 bln. (approximately USD 23 mln.) in the fiscal year ending March 31, 2023.
