In particular, OLED is better at displaying deep blacks, which matters for scenes shot at night or in low light. Which Has the Best Picture?įor now, OLED has better image quality and contrast. There are three so-called “micro pixels” in each OLED pixel, corresponding to the red/green/blue color matrix used to produce colors. In an OLED TV, the pixels emit their own light, which means there’s no need for the LCD screen to display the image. OLED stands for organic light-emitting diode. OLED in TVs, meanwhile, is a fundamentally different technology than that of conventional LED-LCD TVs. So it’s still a conventional LCD-LED sandwich, just with a fancy quantum-dot layer in there to brighten things up a bit. The quantum-dot filter essentially purifies the color of the light coming from the LEDs to get a better, more vivid, and more saturated color. QLED tries to solve that by putting a thin layer, called a quantum-dot filter, between the LED backlight and the LCD screen (that’s where the “Q” comes from).

In these TVs, the LEDs, or light-emitting diodes, function as a backlight, which transmits the image through the LCD (liquid crystal display) screen.īut there’s a big problem with LED-LCD TVs: That backlight color-and how it’s rendered as an image by the LCD screen-can vary pretty widely from set to set. Remember the old “LCD or Plasma?” debate? LCD won handily, and dominates the TV market today. QLED is basically the most advanced version of conventional LCD-LED technology.
