Modern technology is incrediblea marvel of ingenuity, creativity, and talent. The technological revolution of the past century continues to change the world, mostly for the better. Alongside technological innovation, a new vocabulary exists to describe technological advances. Nowhere is this clearer than in the television market. Understanding terminology is critical to getting the best quality at a reasonable price when upgrading your TV. A Liquid Crystal Display LCD is one of the most enduring and fundamental technologies found in monitors, televisions, tablets, and smartphones. TVs and monitors once used cathode ray tubes CRTs to provide the image on your screen.

This is a popular technology today and many electronic devices, including smartphones, tablets, laptops, computer monitors, and televisions, among others, use LED display technology. It is not only useful as the main display screen but also as the interaction medium between the user and the device, such as in a touch screen. The very first occurrence of a solid state diode emitting light was recorded by Captain Henry Joseph Round in The first practical light emitting diode was invented in by Nick Holonyak, Jr at General Electric. Later in the s, LEDs became commercially available, although they were only available in one color: red.

LED LCD vs. OLED: TV display technologies compared

Thinking of putting together or upgrading your home theater setup? There are many factors to consider, but the process often begins with one major question: What kind of TV should you get? These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. Think of it as a shutter, either allowing light to pass through or blocking it out. Each of these illumination technologies is different from one another in important ways. CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels.

A computer monitor is an output device that displays information in pictorial form. A monitor usually comprises the visual display , circuitry , casing, and power supply. Older monitors used a cathode ray tube CRT.

In this article we will provide a comparison of CRT and LCD monitors, along with defining some of the many specifications. When shopping for a new computer system, we tend to fret over such things as the CPU speed or hard disk size, but what about the one component of your system that is used just as much?

All About Monitors: CRT vs. LCD

Here's a look at the pros and cons of each. Now plasma has been removed from consideration. The exception is OLED. They also happen to have the best picture quality CNET has ever tested. OLED may be the picture-quality king, but LCD isn't going down without a fight, introducing all sorts of new technology that could keep the contest close for years to come. So which one is better? Read on for their strengths and weaknesses.

It has two layers of glass which are polarized and stuck together. The liquid crystals are held in one of the layers. These liquid crystals pass, or block the light, to produce images on the screen when the electric current passes through it. However, the crystals do not produce their own light. The light comes from the series of fluorescent lamps at the back of the screen. There are millions of shutters arranged in a grid, which open and close to release and trap some of the light that is not needed to create images. Then each shutter is paired with a colored filter which produces a sub-pixel.

We have all seen the newspaper headlines: screens make us read slower, learn less deeply, remember less and sleep worse. Is this why students prefer to print out their electronic textbooks? We suspected it was habit and attitude rather than measurable cognitive effort during reading that made people prefer print texts, but we needed evidence. Habit and attitude appeared to be important, and a digitally born textbook is by far the best alternative to a print textbook when it comes to studying. But even those who prefer to read on screens are originally native paper readers, and as long as the existing application interfaces cannot address the shortcomings of screens regarding spatial landmarks, we will keep returning to paper under certain circumstances.

 - Что скажешь. А потом мы могли бы… - Выкинь это из головы.

 Руки на стол, - бросила она через плечо.  - Когда я уйду, пожалуйста, никаких глупостей. И у стен есть. Бринкерхофф опустился на стул, слушая, как стук ее каблуков затихает в конце коридора.
