LCD TVs are ruling the roost in today’s TV world. It’s been quite some time since they overtook their heavier plasma counterparts and several improvements have been brought forth for the technology. Still, these TVs are not without their share of problems. Most LCD Television of today suffer from problems that range from motion blur to poor black levels and fuzzy pictures. Described below are five main problems that thwart the performance of LCD TVs.
Poor black levels
No matter how clear pictures are, they can never really satisfy the viewer if deep blue skies look like they’ve just had their faces powdered. Without deep enough black levels, pictures will appear without any zest, whatsoever. On-screen characters might appear to have deep pits around their eyes and shadow detail will be something of a rarity. However, LED TVs came around to safe the day. Known for their stunning blacks and brilliant whites, LED TVs gradually overcame the black level problem that gave plasmas an edge over LCD TVs.
Problems due to viewing angle
This is one of the commonest of LCD TV problems. Slim as they are, the viewer can experience a drastic reduction in picture quality when the TV is viewed from a wide angle. Contrast and brightness levels could get affected, so can colours. But given the advent of new technologies, manufacturers have managed to overcome this problem to some extent.
Dead and stuck pixels
Defective pixels that tend to stand out from the rest on an LCD TV screen can completely spoil the viewing experience. But more often than not, these pixels can be fixed. A stuck pixel will appear to be red, blue or green since it is a pixel that is always in the ‘on’ state. They are mostly caused by manufacturing defects such as a defective transistor. A dead pixel on the other hand is that which is in the ‘off’ state at all times giving it a dark appearance. While a stuck pixel can be easily fixed by applying pressure on the exact spot over a damp cloth for several seconds, a dead pixel cannot be fixed all that easily.
You’re watching Jackie bash up the bad guys in Shanghai Noon. All too jolly, you’re peeved when your Television starts to show signs of blurring in between Jackie’s swift as lighting clouts and kicks. Motion blur can be bothersome, especially when you’re watching a game of football or a high octane movie. By increasing refresh rates to say 120MHz or 240 MHz from 60Hz, manufacturers have been successful in decreasing motion blur to a high extent. Also, several picture processing techniques that can reduce motion blur to the bare minimum have come to play in the recent times.
Colour reproduction problems
Ever since they were first introduced, LCD TVs have had problems with faithful reproduction of colours. However, the same was not the case with plasmas. But again, recent developments have widened the colour spectrum of LCD TVs. There also is the problem of colours having an artificial to them. Manufacturers are doing their best to make colours look as vivid as possible with their natural sheen intact.
