Whether you want to buy a new smartphone, smartwatch, laptop, TV, tablet, or monitor, learning the display configuration plays a crucial role in your purchase decision. However, checking the display specs sheet may be confusing. Terms like OLED, AMOLED, Super AMOLED, Dynamic AMOLED, POLED, QLED, Neo LED, QD-OLED, and more don't tell the whole story. But, when it comes to the top displays, OLED displays are popular. Surprisingly, they're not limited to high-end devices. Most budget Android smartphones have OLED screens.
