LCDs 101

Today will briefly cover LCDs. An acronym for liquid crystal displays, LCDs are flat screen or visual displays that utilize the light from liquid crystals. They exist in many common household electronic screens, such as TVs, computer monitors, cellphones, clocks, even the little screen on your car radio.

Check out this Lilliput UM-70 7″ USB Monitor (on sale!!). Plug the cord into any USB outlet for a fully functioning monitor. No DC power needed!

LCDs work off an array of small pixels. The more pixels and the smaller they are, the better quality screen. You know when your screen resolution says “1280 x 1040” or “800 x 600”? Those are the LCD pixels.

Aside from its well-known uses in TVs and computer screens, character LCD displays are also used for hobby and DIY makers. These LCDs are often numeric (displays only numbers) or alpha-numeric (displays letters and numbers) displays. These DIY projects can be as creative as mounting character LCD displays onto the outside of CPU towers to simulate messages such as the tower’s heat, or even what song is playing on iTunes!

Here’s one of EIO’s more popular character display LCDs: Orient Display 4×20 Character Lcd Display Module.
