OLED vs LED
OLED and LED TVs use different technologies to display an image. While LEDs use backlights behind an LCD panel, pixels on OLEDs emit their own light and don't need a backlight. OLEDs can turn individual pixels on and off, meaning that they display perfect blacks because the screen is completely off when there's a black scene. Since the luminance level of blacks on an OLED is 0, and you can't divide anything by 0, then the contrast ratio of OLEDs is considered infinity to one. Learn more about...
IPS vs VA
Between LED TVs, there are different panel types which each have their own effect on the contrast. Many TVs use Vertical Alignment (VA) panels, while others use In-Plane Switching (IPS) panels. VA panels provide a much higher contrast ratio than IPS, and this is because of the way pixels interact with each other. On either panel type, the pixels rotate to allow light through, which produces the image. However, when there's a black image, the pixels return to their regular position in an attem...
There are a couple of settings that can improve the contrast ratio, with the most important being local dimming. However, changing each of these settings can also affect picture quality, so there's a trade-off between improving the contrast and having the best picture quality available. Also, contrast may vary between units of LED TVs a bit; this m...
Local Dimming:Dims the backlight behind darker portions of the screen. It improves the contrast most of the time, and it's worth using if it performs well. However, it can introduce issues like blo...Contrast: The contrast setting on most TVs increases the luminosity of the brightest whites. This could improve the contrast, but most of the time, it negatively affects image quality.Brightness: Similar to the contrast setting, the brightness setting makes blacks darker when you decrease it. Once again, it can affect image quality, and we don't recommend using it, but it's up t...Dynamic Contrast:Uses software to process the blacks and make them darker. Unfortunately, this removes detail from the image and may not be worth using.The contrast ratio of a TV defines how well it displays blacks. The higher the contrast, the better, as it improves picture quality in dark scenes. If your TV has a low contrast ratio, blacks look gray. A high contrast ratio is most noticeable when viewing content in dark rooms, but there's less of a noticeable difference in well-lit rooms. Althoug...
Mar 19, 2015 · Contrast ratio is one of the most important aspects of picture quality, yet it's poorly understood and often not even mentioned on TV specification sheets anymore. Here's what you need to know.
