OLED technology uses organic light emitting diodes to create brighter, thinner, and more flexible displays. An OLED is composed of thin films of organic molecules that emit light when electricity is applied. The first OLED was developed in 1987, and since then OLEDs have been used in various displays. OLEDs offer advantages over LCDs like higher contrast, better viewing angles, and less power consumption. Major applications of OLEDs include televisions, smartphones, and laptops.
