Plasma TV vs LCD TV
What's the difference? The terms “plasma” and “LCD” are often used interchangeably when referring to flat-panel TVs. In reality, plasma and LCD TVs are very different. Plasma screens use small plasma cells charged by electrical voltage to produce a picture. LCD (Liquid Crystal Display) screens use liquid crystal layered behind two sheets of glass, which is then charged to create a picture.
While both technologies can offer excellent results, there are differences in performance and picture quality. We’ve outlined the differences and the benefits of each below.
Overall picture quality
Plasma is great at producing dark tones but recent advances in LCD technology mean they too now offer excellent results in darker tones. What’s more, advances in image processor technology have added to LCD’s performance – the BRAVIA ENGINE 3 is a good example of this as it enhances contrast and delivers more accurate colours.
Motion
Plasma was traditionally superior in conveying motion but recent advances in LCD technology have eliminated this difference. Furthermore, innovations such as Motionflow 200Hz which adds extra frames into action sequences have made LCD hard to match for smoothness and detail in action scenes.
Performance in brightly lit rooms
If turning off the lights for that ‘cinema at home’ feel isn’t possible – perhaps someone else wants to read or eat in the same room then an LCD is more suitable. LCDs perform better in bright rooms and are therefore often used for public display. Plasma screens are much more at home in darker environments.
To make sure the picture is optimised for your viewing environment, BRAVIA LCD TVs have light sensors that automatically adjust the brightness of the screen according to how much light there is in the room.
Burn-in
Although a diminishing problem, Plasma TVs still have trouble with images ‘burning in’ to the screen. So for example if you watch a news channel that constantly has the logo on screen, that image could be permanently etched onto your TV.
PCs & gaming
With more pixels per square inch on an LCD display compared to other display technologies, LCD monitors are especially good at displaying large amounts of data with exceptional clarity and precision. So LCD monitors display images from computers or games consoles extremely well, with full colour detail, no flicker, and no screen burn-in.
Energy consumption
With energy costs rising and green issues increasing in importance, power consumption is a key consideration when purchasing a TV. LCD TVs use considerably less power than plasma screens – up to 50% less power in many cases.
Looking ahead
LCD’s 80% share of the market suggests that it does have some key advantages but there’s no substitute for having a look around to see for yourself, especially in a market where new features and benefits are being added at such a pace. 100 or 200Hz refresh rates for LCDs and LED backlight technology are two recent examples of progress in LCD technology.
