Plasma and Character LCD Modules contrast

Contrast refers to the measurement of different brightness levels between light and dark areas in an image of the brightest white and the darkest black, the greater the difference between the representative of the greater range of contrast , the smaller the difference between the representative of the range of the smaller contrast ratio of 120 good : one can easily display vivid, rich color , when the ratio of up to 300:1 , you can support the color of each floor . However, the ratio of suffering and the plight of the same brightness , today there is no effective and equitable set of criteria to measure contrast ratio , so the best way is to rely on user identification eye .

Typically contrast ratio LCD TVs LCD display indicator is higher , ranging between 600:1 to 1500:1 .Tsingtek OLED Display Module However, we sometimes see some of the products will be advertised in the publicity when the parameters of ultra-high 10,000:1 dynamic contrast ratio and the like, so that consumers mistakenly think that the product than other similar technology a couple of notches higher , this is a playing with the concept of the place of text . Misunderstanding the concept that "dynamic" above the word , dynamic contrast ratio refers to the contrast of the LCD TV value under certain circumstances measured , such as one by one test each area of ​​the screen , the contrast maximum contrast value area , as the contrast parameters of the product . Method for measuring different manufacturers are not the same dynamic contrast ratio , usually with a dynamic contrast ratio of the value of the product is 3-5 times the contrast even higher . Therefore, a so-called ultra-high "dynamic" contrast ratio of the actual contrast TV does not necessarily higher than other products , and the contrast of Tsingtek TFT LCD Displays TVs currently has about 1500:1 is the limit.

Plasma are reached 1000:1 contrast ratio generally above , there are some products up to 10,000:1 or more, more than enough to meet the general needs of 2000:1 buy most occasions. NeoPDP using a newly developed phosphor technology , to enhance the contrast 40000:1 .
