I have 3 tvs in my house I often find myself watching tv in the basement where my Plasma is just because the LCD looks terrible in the dark why is this so
In: Technology
Plasma’s pixels can individually turn on and off. Think of them as little tiny light bulbs.
LED and LCD displays don’t work that way. Instead there is a giant backlight that lights up the whole screen (we’ll simplify and ignore zones for this explanation). Each pixel has a liquid crystal that can twist. Twisted in one way and it blocks light, twisted another way it lets light through. Think of LCD as millions of tiny little doors. When pixel is on, the door is open.
If you’ve ever been in a dark hotel room with the hallway lit outside, you would’ve noticed that there is always a little bit of light leaking through the bottom and edges of the door. Same thing here. The liquid crystal cannot block 100% of the light, and therefore a pixel is never truly dark. This degrades contrast and picture quality, as the whole picture has a greyish tint to it.
