While OLED technology has existed since the 1960s, the first practical OLED display wasn’t built until 1987. Not that you could buy it of course, but over the last twenty years improvements in the manufacturing processes have made mass-production a reality.
In that time we’ve gone from 15-inch OLED TVs that cost a fortune to affordable models that support 4K (and sometimes even 8K), High Dynamic Range (HDR) and High Frame Rate (HFR). Nowadays, every major TV brand offers OLED TVs, although recently you may have read about two different types: WRGB (W) OLED and Quantum Dot (QD) OLED. So how do these panel technologies differ and which is better?
