Today, while the Internet has managed to steal the attention of millions of people worldwide, many still tend to turn to the TV for some good, old-fashioned quality entertainment. LCDs are in, CRT monitors are out. Even when you go out to the train station or to the mall these days, you’ll most likely encounter at least one TV on the way that shows various advertisements in an endless loop. These TVs are called industrial LCD displays, which are televisions used for advertising purposes.
Drawbacks of Industrial LCDs
LCDs still have several drawbacks when compared to other display technologies. The following are some examples:
LCD screens are much more susceptible to damage than CRT monitors are. CRT monitors are generally constructed with protective glass. LCD monitors, in comparison, consist of a soft fiber stretched over the screen area.
While LCDs are better at retaining color and contrast in bright environments, they also have lower contrast ratios. This means LCD technology has yet to achieve the deepness of black that is common in CRTs.
LCDs have lower response times than CRTs. This creates “ghost images” when the images on screen change rapidly.
LCDs have a limited viewing angle compared CRTs.
Some LCDs can cause eye strain and even migraines when viewed for long periods of time.
Some of the best manufacturers of industrial LCDs today are Viewsonic, Sony, Dell, LG and Samsung.
