What is the ratio of dynamic contrast?

Dynamic contrast ratio is an evaluation used to measure the quality of the TV image. The standard or static contrasting ratio of the TV shows the brightest white colors on the versus the deep and dark shades. In fact, the contrast ratio is actually reported by the buyer about the extent between dark and bright colors, which can help the buyer compare the quality of the image between different units.

Newer TVs often have a second type of contrast rating, known as a dynamic contrast ratio. The dynamic contrast ratio measures the maximum range of colors between white and black shades. It requires a special feature on television that adjusts the brightness of the display to maximize image quality. For example, if viewers watch a film with a lot of shadows and darkness, the processor in the unit increases the brightness to improve contrast. TV with this function can theoretically provide a much higher contrast ratio than standard TV Models.

Dynamic contrast ratio and Sta ratioTical contrast are expressed using a number of numbers, such as 500: 1 or 1000: 1. The greater the difference between these two numbers, the better the image quality should be. In general, LED (LED) light -emitting TVs (LED) can provide the highest dynamic contrast ratio because the LEDs are capable of very bright lighting levels. Many liquid crystal (LCD) and plasma TVs also provide dynamic contrast options, although this feature is not available in all models.

The buyers often rely on the manufacturer's extracts and compare the dynamic contrast ratios between different models. Due to changes in contrast measurement, this is not a often effective way to compare different brands or even models within the same brand. Some manufacturers test dynamic contrast in a controlled laboratory environment while others test this ratio in settings that resemble a typical livingto the room. The contrast ratios will always be higher in a controlled environment than in uncontrolled environments, making it difficult to compare television units based on this function.

Generally evoke TVs with dynamic contrast settings a better viewing experience. Viewers will notice fewer shadows and better color contrast. As brightness levels are adjusted, it is also easier to see all the action on the screen, even in the deep shadow areas. At the same time, some viewers may not like this function, they believe it is too brightening or darling. It is often better to visit shops and compare the quality of the image instead of relying on contrast conditions and other evaluations provided by manufacturers.
