OLED iMac Panel Could Include Extra Layer to Fight Screen Burn-In

LG Display is processing a five-layer OLED sheet operation that could extremity up successful a aboriginal iMac, with an other furniture added to forestall surface burn-in and summation brightness, reports The Elec.


LG Display already builds four-stack OLED panels for high-resolution monitors, and arranges the light-emitting layers successful a blue-green-blue-red pattern. The five-stack mentation reportedly nether improvement adds a 3rd bluish layer, creating a blue-green-blue-red-blue arrangement.

Stacking connected different emitting furniture spreads the electrical load, which is important astatine precocious pixel densities, wherever each pixel gets smaller, arsenic does the information of it that really emits light. Pushing much existent done a smaller emitter to support brightness up is besides said to shorten sheet beingness portion making representation retention much likely.

Apple past twelvemonth sent requests for information to Samsung Display and LG Display astir iMac OLED sheet development. The specifications discussed were a 24-inch sheet with 600 nits of brightness and 218 pixels per inch. The existent 24-inch iMac's LCD manages 500 nits astatine the aforesaid density.

LG Display has already demonstrated a 27-inch 5K sheet astatine 220 PPI with an RGB stripe subpixel layout. Given it uses the four-stack structure, it is apt not destined for an iMac, but The Elec suggests it is simply a gauge for high-density RGB stripe OLED and whether the institution tin manufacture it successful volume.

The lone occupation with utilizing 5 stacks, however, is cost. More emitting layers mean much integrated worldly and a reportedly fiddlier deposition process. At the aforesaid time, LG Display has to scope Apple's brightness and lifespan requirements without ruining its yields successful the process.

Samsung Display is processing QD-OLED for the aforesaid reason. Both suppliers are targeting 2028 to person the archetypal iMac OLED panels developed, but a motorboat apt won't hap until 2029 astatine the earliest. Meanwhile, Apple is expected to refresh its existent 24-inch LCD-based iMac with a caller processor later this year.
