[Asia Economy Reporter Changhwan Lee] LG Display announced on the 5th that its OLED (Organic Light Emitting Diode) has opened the era of ‘Flicker Free’ for the first time in TV panels.

Flicker refers to the rapid blinking of lights or screens, which is divided into visible flicker and invisible flicker. Even invisible flicker is known to cause headaches, eye fatigue, and vision deterioration when exposed for a long time.

The flicker phenomenon can be easily observed by filming a TV with a smartphone’s slow-motion video or by looking at a TV through the blades of a running portable fan.

With the increase in TV viewing time due to COVID-19 and the expansion of online classes for teenagers, the importance of eye-friendly displays has grown, and the company explained that it is presenting ‘Flicker Free’ as a new standard for choosing TVs.

LG Display emphasized that it has obtained ‘Flicker Free’ certification and verification marks from the German international certification body ‘TUV Rheinland’ and the global safety science company ‘UL’ for all OLED TV panel models ranging from 48 inches to 88 inches.

According to measurements by ‘TUV Rheinland,’ LG Display’s OLED TV panels, due to their self-emitting light structure, showed 0% invisible flicker, receiving the ‘Flicker Free’ certification for no flickering. Also, UL’s measurements showed flicker at 1.3%, far below the standard of 9.6%, earning the ‘Flicker Free’ verification mark.

In contrast, LCD (Liquid Crystal Display) TVs cause invisible flicker because their backlight LED light source emits light by flickering at very short intervals.

Previously, OLED TV panels were recognized as eye-health-friendly displays by lowering blue light emission, which causes eye fatigue and sleep disorders, to the industry’s lowest level, receiving the ‘Low Blue Light’ certification from ‘TUV Rheinland’ and the highest blue light safety rating from ‘UL,’ which is 50% lower than the harmlessness standard set by the International Electrotechnical Commission (IEC).

As the number of OLED TV manufacturers recently confirmed to launch has increased to 19, LG Display plans to allow global OLED TV customers and distributors to utilize the ‘Flicker Free’ and ‘Low Blue Light’ certifications and verification marks as part of the ‘Large OLED Mainstreaming’ initiative.

Oh Chang-hoo, Vice President and Head of LG Display’s TV Business Division, said, “As TV viewing time increases in the COVID-19 era, the importance of eye-friendly TVs is growing,” adding, “Through this certification, consumers will be able to choose OLED TVs with confidence.”
