Users questions:What size of LCD screen brightness visual contrast ratio performance, reaction time pitch resolution bandwidth consumption of power, Safety Certification really do not understand! ! Very professional, and selection of liquid crystal displays What is the key? Please recommend some good 1800-2800 a liquid crystal display 7,777,771) Main technical parametersAnd the visual effect of: a.

The greater the demand the higher the screen view angle; TV demands a large field of vision angle than the display. d. Response Speed: gray-scale response to be meaningful, the unit is milliseconds (ms). The faster response to the smaller screen of the trailing phenomenon, mainly playing games and watching films has requested more thanHigher. e.
