Pixel pitch plays a significant role in the calibration process for LED advertising screens. The pixel pitch, which refers to the distance between the pixels on the screen, affects the resolution and clarity of the displayed content. When calibrating LED screens with different pixel pitches, adjustments need to be made to ensure that the colors are accurately represented across the entire screen. This process can be more complex for screens with smaller pixel pitches, as the individual pixels are closer together and require more precise calibration.
Earlier this year we reported that Apple has decided to sign up BOE as its AMOLED supplier for the upcoming budget iPhone SE4 (with a 6.1" AMOLED display). According to reports back then, Apple's low price target ($25) was not profitable for Samsung that decided to not supply any AMOLEDs for this iPhone model. According to new reports from Korea, Apple now signed up LG Display to supply some of its iPhone SE4 panels - mostly backup (BOE had its issues with Apple before) and support, as BOE will remain the main panels supplier.

OLED emitter materials are the heart of the OLED device, and the materials that make the most impact on the performance of the OLED display. Most OLED displays utilize red, green and blue emitters. The efficiency of the current state-of-the-art commercial red and green OLED emitters is excellent - it is in fact close to 100% internal quantum efficiency (IQE) which means that you cannot improve much on the efficiency of the emitter itself (there's still work to be done on getting the light out of the device). Blue OLED emission is a completely different story - current commercial blue emitters suffer from very low efficiency, around 25%. This means that three quarters of the energy goes to waste. Changing to a 100% IQE blue emitter could end up improving the total display efficiency by 20-30%.
