AR coating, where AR stands for Anti-Reflection, is a technology that involves applying an anti-reflection layer onto a film or another substrate. This layer helps to reduce reflected light, thereby minimizing surface reflections and glare on the screen. By coating a thin film layer onto the surface of the substrate, it becomes possible to incorporate various additional functions.

We will elucidate the principles and applications of DNP's display enhancement films, including AR film, AG film, and retardation film. DNP's display enhancement films function by suppressing surface reflections and minimizing glare on screens through the reduction of reflected light. The application of these films leads to a diminished impact of ambient light on LCD screens, resulting in a clearer display. In a similar fashion, retardation film finds application in OLED displays to mitigate reflections. Beyond their use in OLED displays, the display enhancement films are extensively employed in PCs and tablet devices, establishing themselves as commonplace and well-recognized products.

Retardation films are optical components designed to enhance the contrast and expand the viewing angle of displays. Liquid crystal displays (LCDs) and OLED(Organic Light Emitting Diode) displays are used in a wide variety of applications, from televisions to smartphones. However, both LCDs and OLEDs face issues such as color distortion and reduced contrast caused by reflections from sunlight and ambient light. The main cause of color distortion in LCDs is the optical shift (retardation) that occurs when light from the backlight passes through the liquid crystal layer. To address and compensate for this optical shift, retardation films have been developed. In OLED displays, contrast reduction is caused by the reflection of sunlight and external light onto the electrodes. To minimize this impact, a circular polarizer, which combines a linear polarizer and retardation film, is used to reduce the reflection of external light.
