One main difference between LED displays and Mini-LED/Micro-LED or LCD displays is the size of the dot. In the case of OPD-M21610(1)LR-GW, the 12 x 12 Dot Matrix LED display consists of 144 dots with a dot diameter of 1.9mm and a pitch of 2.54mm.
Overall, a thin profile, high ppi, and high η W make the performance of CC μLED emissive displays stand out, while the OLED display and mLED-LCD are mature and economic choices. Fig. 9
