How Touchscreens Work

In our last article we told you all about how LCD screens work. In that piece, we talked a little about the history of LCDs and how important they’ve been to the rise of personal mobile electronics like smartphones, tablets, and laptops. Today we’re going to talk about another crucial component of this technological revolution: the touchscreen. The first touchscreens were designed in the 1960s, but the technology was expensive and imprecise. It wasn’t until the 1990s that there were serious attempts to bring touchscreen technology into the consumer world. IBM was the first company to attempt to bring the technology to mobile phones, with the Simon in 1993, while Sega made an aborted attempt to incorporate touchscreen technology into mobile gaming. It wasn’t until the early 2000s, with the introduction of PDAs and early smartphones, that touchscreens began to see use in mobile electronics.

Pretty much all modern touchscreens fall into two basic categories: resistive touchscreens and c…

How LCD Screens Work

Liquid Crystal Display (LCD) screens have played a major role in the rise of personal digital technology. The first LCDs were used in calculators and digital watches in the 1970s, and the technology began to make its way into televisions and computer displays in the 1980s. During the early 2000s, the technology made its way into smartphones and PDAs. In 2007, the same year Apple introduced the first iPhone, LCDs surpassed CRT (cathode ray tube) displays in both sales and picture quality.


Every LCD consists of 6 basic parts. At the back of the display is a backlight (though in some devices like calculators and digital watches, it’s just a reflective surface). In most displays - including the one on your phone or tablet - the backlight consists of an array of light emitting diodes (LEDs). In front of the backlight is a polarized film (like you’d find in a pair of polarized sunglasses). This film only allows the light waves that are oriented vertically to pass through. Next is a layer of…

Certain things in life are inevitable. The old joke goes that the only two certainties in life are death and taxes, but the truth is, there are a few more things that you can’t really escape. One of them is a damaged phone. If you own a cell phone, then sooner or later it’s going to get dropped, wet, or dirty. Maybe it slips out of your hand as you're opening your car door, maybe it gets dropped in the sand on your day at the beach, or maybe a careless elbow and a knocked-over glass splashes it with water. One way or another, the odds are good that sooner or later your phone is going to experience some rough times.

The best thing you can do to prepare yourself for that fateful day is to have your phone in a good case. But what, you may ask, makes for a good case? That’s an excellent…
