Currently, the liquid crystal display (also known as "Liquid Crystal Display" or just by the acronym LCD) is no longer one of the most popular among electronics - since the LED dominated several segments for being thinner, lighter and more resistant -, but if you've been wondering how this technology works, Canaltech explains it.LCD, IPS, OLED, AMOLED: what sets smartphone screens apart?Are there still CD/DVD players?Before the arrival of LCD, plasma was the most adopted solution in displays around the world, but with the debut of liquid crystal technology everything changed, as components became thinner and increasingly easier and cheaper to produce.The term “liquid crystal” of LCD comes exactly from the material used to produce the display.Found in both a solid and a liquid state, the solution of liquid crystal molecules is condensed into a thin, rigid structure that, when it receives an electrical discharge, expands into an interconnected format to allow for the display of images.And in order for us to see the images on the screen, we need the pixels.Each LCD screen pixel is made up of three subpixels: one red, one green and one blue (red, green and blue, or just RGB).Screens can support millions of subpixels (in displays with Full HD resolution, for example, there are more than 6.2 million subpixels), and TFT is required to activate this component.Short for “Thin-Film Transistor”, the TFT is an electrically powered semiconductor device that supplies the necessary power to each sub-pixel.Another component needed to bring images to life are polarizers.Two sheets are placed on either side of the TFT LCD assembly and control the passage of light to the screen surface.Finally, we have the basis of the sandwich of LCD screens: the light source (backlight).Formed by a layer of fluorescent lights, this panel is positioned behind everything mentioned above (polarizers, TFT and LCD) to consistently illuminate the entire screen and allow brightness control.The structure of LCD screens has evolved a lot in recent years, and recently we see a pattern repeating itself in the industry:Glass, plastic or protective filmThis is the sandwich you can find in a few products that are still sold with LCD screens, especially extremely cheap monitors and TVs, which shows that even the most everyday things have incredible technology behind them.Programmers earn up to R$8,900 per month in Brazil;see languages ​​on the riseNerd Pride Day: 10 things every self-respecting nerd doesQuiet place?Rover Perseverance records the natural sounds of MarsChina launches world's first aircraft carrier capable of operating on its ownChina considers use of anti-satellite technology if Starlink becomes a threatBRASILIA (Reuters) -
