A basic LED LCD with its backlight set low will draw less power than OLED.
The only way to make OLED more energy-efficient is to reduce its brightness, but since that reduces its contrast ratio as well, it’s not ideal.
So we’ll give this category to LCD, even though it’s fairly close and neither uses much power.
What is the difference OLED and LED?
OLED stands for “organic light-emitting diode.” Very simply put, OLEDs are made with organic compounds that light up when fed electricity. That may not seem like a huge difference when compared to LEDs, but unlike LEDs, OLEDs can be made to be extremely thin, flexible, and even rollable.
Is OLED TV worth buying?
LG is the main brand that flogs premium OLED screens, but you’ll also find other firms selling them — including Sony. OLED screens are generally better than conventional LED-backlit LCD displays. For a start, they’re much more power-efficient.
Is OLED better than 4k?
Winner: OLED TV
The lighting is close to the front of the screen panel than with LED backlit TVs. LED 4K TVs with edge lit or even full array backlighting should be equivalent to the best LED TVs in side angle viewing quality. While they are getting better, they lag behind plasma and OLED.
Why is OLED better?
Rather than an array of individual LED bulbs, OLED uses a series of thin, light emitting films. This allows the OLED array to produce brighter light while using less energy than existing LCD/LED technologies. There are additional flavors of OLEDs that are better for different kinds of devices.
