The evolution of TV technology has shown a dramatic improvement over the past few years with better promising technology in the horizon. On one side there is 4k TV which has the capacity to produce 4 times the resolution of your TV. On the other side is OLED (Organic Light Emitting Diode) TV a technology adopted by LG that has the capacity to produce unrivaled picture quality. Unlike LED screens that use a combination of Liquid Crystal Display and backlight technology to produce an image, OLED technology uses a panel that emits light only when an electric current passes through them. This makes OLED TV have an edge over LED screens in dark scenes.
A 4K TV, on the other hand has a resolution of 3,840 x 2,160 around eight million pixels which is 4 times the resolution of a conventional full HD TV (1920 x 1080). This giant resolution is capable of producing crystal clear images with sumptuous details. While LG has proved that an OLED TV can also be 4K, in this article we will be comparing OLED 1080p resolution with 4K LED backlit TV. Currently, only LG is producing OLED TVs-a technology that has proved to be quite complex to manufacture according to manufacturers. However, virtually all other TV manufacturers have a line of 4K TVs in stock. So, what’s more exciting? Let’s see the comparison of both technologies in detail. This comparison is between LG EC930V (OLED TV) and the best 4K TVs of 2015: Samsung JS9000 and SONY KD- 65X9000C.
OLED TV vs 4K TV: BLACK LEVEL
In this area LG OLED TV by far outshines the SONY and Samsung 4K LED TVs due to its pixel dimming technology. Since each pixel can control their own luminance, they can turn on and off independently achieving a black level that is unattainable by ordinary TV. LED TV relies on a backlighting system to illuminate the screen. This means that even the deepest blacks will still be illuminated a little. While there have been a remarkable improvement in black level rendition from LED screens, it is still a long way to go to get to the level of OLED. Some SONY TV’s utilizes a local dimming technology that nearly achieves a perfect black level but due to the dimming technology, it appears gray when put side to side with LG OLED.
WINNER: LG OLED
OLED TV vs 4K TV: BRIGHTNESS
There is no competition when it comes to brightness and resolution. With a resolution of 3840 by 2160 which is almost four times that one of OLED (1920 X1080) 4K TV is the winner here. Again since the pixels in OLED lights on and off individually, they may not be able to keep up with the peak white. However, this does not mean that the OLED TV is not bright; its infinite contrast is enough to give you a near perfect clarity though not as good as 4K. The jump in 4K resolution is more noticeable in bright scenes.
WINNER: 4K TV
OLED TV vs 4K TV: COLOR RENDITION
Color rendition in 4K TV’s is just an improvement from LED. While it is significantly improved, the richness in content is slightly lacking. In OLED displays, each pixel is made up of green, red and blue elements which work together to provide a million colors. When this is combined with the infinite contrast ratio the colors pop out of the screen creating a live-like experience. In this case, the chromaticity coordinates are more accurate in OLED than in 4K TVs. SONY TV’s would compete well with OLED in color rendition due its unique Triluminos display as observed in SONY 2013 model (KDL-55W900A) and some few 2015 models. SONY uses the quantum dot technology to widen the color gamut by 50%. The quantum dot consists on nano-crystals that enhance the red, blue and green colors.
WINNER: OLED TV
OLED TV vs 4K TV: SIDE ANGLE VIEWING
All LED panels suffer from side angle viewing and Samsung 4K LED TV is no exception. Plasmas are known to have very good side angle viewing, but production of plasma TVs is on the verge of collapsing with the advent of OLED. What about OLED TV’s side angle viewing? The LG OLED EC930V shows incredibly consistent picture viewed from various angles, thanks to the beautifully designed curved screen. The contrast does not diminish with changes in sitting position which makes OLED very promising in this area as well.
WINNER: OLED TV
OLED TV vs 4K TV: SHARPNESS-IMAGE CLARITY
Sharpness is what 4K is all about. The quality of sharpness is also enhanced by how well the 4K TV converts 1080p to 4K resolution. This is especially important owing to the limited 4K content. SONY is a master in the conversion of native content to 4K with its new android TV KD-65X9000C. Not even OLED can get closer to the sharpness and image clarity produced by this TV. It combines the iconic Triluminos display with a powerful 4K processor X1 chip and a 4K X-Reality Pro engine to take picture clarity to a different level. Though the LG OLED TV EC930V also has incredible sharpness compared to other TV’s it cannot beat 4K in this area.
WINNER: 4K TV
OLED TV vs 4K TV: SCREEN UNIFORMITY
Screen uniformity is a major problem with most if not all edge lit LED TVs. Even the best 4K TVs like SONY 65X9000C and Samsung JS9000 have several reported cases of light bleeding. Sometimes they show a brighter background in some parts of the screen or black level that is not evenly distributed throughout the screen. In OLED, each pixel produces its own light which is evenly spread out in the entire screen. In dark scenes, the screen goes off completely such that you might be tempted to think of a power blackout. This enhances the beauty of the entire image.
OLED TV vs 4K TV WINNER: OLED TV
The choice of a TV should entirely depend on the use to which you wish to put it. For picture quality and a dazzling movie experience, OLED TV carries the trophy. This is due to the unprecedented perfect black levels, picture rendition, motion blurs and screen uniformity which beat 4K TV’s black and blue. However, such features come at a cost. If the screen major use is for general content and music that gets embellished by sharpness, brightness and contrast then 4K TV is the best for you.
