LG Display announced that all of its large-sized OLED panels, including those for TVs and monitors, have been recognized for their “perfect dimming technology.” 

LG is the first to earn the industry’s first “100% dimming consistency” verification from UL Solutions, a global leader in applied safety science. This performance, as validated by UL Solutions, objectively demonstrates the superiority of OLED’s pixel-level dimming.

Dimming consistency refers to a measurement method that evaluates, in percentage terms, how effectively a display reproduces content based on its brightness performance. A reference area is set in the center of the screen and is gradually reduced from 1/10 of the panel to 11/1000, 5/1000, and finally 2/1000.

LG Display’s OLED maintained the same brightness performance even as the test reference area decreased, achieving a dimming consistency rate of 100%. 

Because OLED panels emit light at the pixel level, with pixels measuring only about 0.1 mm², they can maintain brightness even when the test reference area is reduced, reproducing natural colors and clearly distinguishing color boundaries. This means they can faithfully express the content creator’s original intent.

LG Display’s new OLED TV panel applies its proprietary “Primary RGB Tandem 2.0” technology, which emits light by stacking the three primary colors of light – red, green, and blue – in independent layers. 

It delivers a peak luminance of up to 4,500 nits (one nit equals the brightness of a single candle) and incorporates technology that absorbs and disperses light rather than reflecting it, achieving the lowest reflectance level (0.3%) among existing displays.
