LCD TV Contrast Ratio Explained

What is Contrast ratio?

Contrast ratio of the LCD TV is the way to measure the intensity of the colors that it can show. The ratio is calculated between the darkest shades and the brightest shades that a LCD display can provide. This ratio is created by the difference in the intensity of the light.

Methods to measure contrast ratio of LCD TVs

The contrast ratio of any LCD TV should be tested in a place where there is no possibility of the light getting reflected. The light that is emitted from the television should get absorbed completely to enhance the viewing experience. The other method of measuring contrast ratio is called the "Ansi contrast". This is the most accurate way of testing because the lights and other conditions of the room are carefully controlled. The ratio measured is the static contrast ratio where the dynamic ratio is calculated with the off and on method. No one method to measure the contrast ratio is perfect, as every manufacturer has its own parameters to judge.

Technologies to improve contrast ratio

The latest models of LCD TVs use modern technologies like Super Patterned Vertical Alignment and Patterned Vertical Alignment that enhance the angle of viewing and intensify the color level. In order to view the darker scenes on the display in a room with bright background lights you need better depth of black which is possible with lower response time. These two recent mechanisms increase the contrast ratio of the screens up to 3000:1.

Home methods to improve contrast ratio

If you are facing some problems with the contrast ratio of the television then there is a technique that you can try at home. Simply illuminate the background wall where you have placed the LCD TV as this will make the screen look darker than usual and you will get a better contrast ratio.
