LGD's WOLED panels earn the industry's first 100% dimming consistency certification from UL Solutions

LG Display announced that its WOLED panels have been recognized for their “perfect dimming technology” – earning the industry’s first “100% dimming consistency” verification from UL Solutions. LGD says that this certification objectively demonstrates the superiority of OLED’s pixel-level dimming.

LGD explains that dimming consistency refers to a measurement method that evaluates 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. The results are expressed as a percentage: if the maximum and minimum brightness values remain the same throughout the process, dimming consistency is 100%. Conversely, as the value decreases, it means that there is light intensity variation within the same screen. In such cases, brightness differs depending on the position of the light source, even for the same color.

LG Display says that its WOLED panels (used to make TVs and monitors) maintained the same brightness performance even as the test reference area decreased, achieving a dimming consistency rate of 100%. In contrast, LCD-based panels became dimmer as the test reference area shrank, with dimming consistency dropping from a maximum of 83% to as low as 43%.
