DNP Develops Light Diffuser Film for Mini-LED Displays that Improves LED Elements Appearance

Dai Nippon Printing Co., Ltd. (DNP) has developed a light diffuser film for mini light-emitting diode (LED) backlights that achieves vivid screens with low power consumption. The newly developed film makes it possible to realize the same brightness and reduce the appearance of LED elements like dots, without using the diffusion plates employed in conventional mini-LED displays. In turn, the new film allows for a reduction in the thickness and weight of the display.
In addition, the newly developed film was published as a Special Section Paper in the Best of IDW2023 on the website of the Journal of the Society for Information Display (Journal of SID), a world-renowned display-related journal.

Mini-LEDs and micro-LEDs have recently been attracting attention as next generation displays, following liquid crystal and organic light-emitting diode (OLED). Mini-LEDs feature diameters of about 100 to 300 μm, where 1 μm = 0.001 mm, densely mounted on a panel substrate. They are characterized by their low power consumption and vivid image quality due to their high brightness.

Such displays have begun to be used in some televisions and personal computers, and going forward are expected to extend into small electronic devices, leading to a global market expansion1.

On the other hand, mini-LEDs use diffusers and special printing patterns to reduce reflections, as the dots densely arranged on the panel substrate are easily visible to the naked eye under high resolution conditions. Increased power consumption is also an issue due to the thick diffuser resulting in lower light transmittance.

DNP's light diffuser film can reduce the appearance of dots without the diffuser, contributing to thinner displays and reduced power consumption without any reduction in brightness.
