Reducing sparkling on self-illuminating displays with a phase-separated AG film

Our phase-separated AG films excel at reducing sparkling on self-illuminating displays such as organic EL displays.

What is sparkling?

  • Generation of sparkling
    Generation of sparkling

    Unevenness of luminance is generated by lens effect

  • No sparkling
    No sparkling

    Lens effect does not generate.

Principle of measurement

Standard deviation of luminance distribution of the sparkling shot is evaluated as “quantified value of sparkling”

Advantage of phase-separating AG film over organic EL

Using phase-separating AG film can reduce the sparkle (compared to filler AG) seen with organic EL displays (OLED).
