Today Samsung Display Company (SDC) is asserting the introduction and mass manufacturing of a brand new technology of OLED panel known as “Eco²OLED”. While the information right here is fairly quick, it’s really a large technically endeavor and shift from previous technology OLED panel applied sciences, as the brand new panel sort is making due with out the classical polarizer layer in-between the precise panel and canopy glass.
In a standard OLED panel, the precise panel itself is of a copper color, which in fact doesn’t work very properly for displaying black. To create a reflective black, shows use polariser layers which block gentle from getting into and reflecting off the show, solely permitting gentle generated by the show itself to undergo the glass.

The drawback with such layers is that they’re of a decreased transmittance, and the polarizer itself is consuming among the gentle emitted by the panel. The above image for instance is the quilt glass and polarizer of an outdated Galaxy S7, which seems notably darker than the lit background.
Samsung is explaining that they’ve managed to do away with this polarizing layer, and are capable of have non-reflective OLED panels which show as black. This is a serious change within the show stack, and Samsung is quoting that they’re capable of enhance transmittance by a large 33%, that means 33% brighter screens, or on the identical brightness, scale back energy consumption by 25%.
These figures are large, and may signify one of many largest jumps in energy effectivity in OLEDs since their inception.
Samsung Display states that the Eco²OLED is already being utilized in Samsung Mobile’s Galaxy Z Fold3, that means this ought to be the primary telephone to have the ability to make the most of the expertise. Along with this yr’s widespread adoption of LTPO panels which massively improved energy effectivity, this might sign a brand new massive bounce in smartphone energy effectivity and assist enhance battery lifetime of units adopting the expertise.
