Blog - 1-2020-OLED Vs. LED


When shopping for the newest and best televisions this year, the two main competing versions of display are the OLED and the LED TV’s. Both technologies offer super-slim designs and sharp, detailed 4K images, but there are some picture quality differences.

The main difference between an LED and OLED television screens  is that the pixels of an OLED screen are self-illuminating, whereas the LED are used to light an LCD display. An OLED screen features a wider viewing angle than LED screens do, and they are also more energy-efficient when compared to their LED counterparts.

LED TVs use LCD display technology and an LED backlight to illuminate the screen. LED LCD displays tend to use ‘edge lighting’, where LEDs sit to the side of the display, not right behind it. The light from these LEDs is then fired through a matrix that feeds it through the red, green and blue pixels and into our eyes. The light of an OLED display can be controlled on a pixel-by-pixel basis. This sort of dexterity just isn’t possible with an LED LCD. There are three types of LED backlight: edge-lit, direct-lit, and full array. The backlight means that LED TVs can get very bright, so the picture looks vivid even with room lights on.

Some high-performance LED TVs use "quantum dots" to increase brightness and color range, OLED TVs don't require a backlight because every pixel is self-illuminating. Because of this and the fact that every OLED pixel can switch off completely, these TVs can produce absolute black and infinite contrast. OLED TVs tend to look best in a dim or darkened room. OLED TVs also provide much wider viewing angles than LED TVs, which lose picture contrast and color as you move away from directly in front of the screen.

OLED TV has secured a strong presence  in the premium TV market. LG Electronics is the most successful brand using LG Display’s OLED TV panels. LGD also supplies OLED panels to other companies including Panasonic, Sony, Grundig, Philips, Metz, Loewe, Skyworth, Changhong, Haier, Konka, and others. The OLED vs. QLED battle goes beyond Samsung and LG. Other brands beyond LG also sell OLED TVs including Sony and, later in 2020, KonkaSkyworth and  Vizio.

Based on what we've seen working with these manufacturers to supply our clients with the best TV's for their home media rooms, especially when it comes to setting up their Home Theaters, we continue to expect OLED to produce superior image quality to QLED. We look forward to seeing how these industry leaders continue to blow our minds with better, clearer displays to enhance the overall user experience.
