In a true LED screen, each pixel is a diode that emits light itself.<\/strong> However, there&#039;s an important caveat: TVs and monitors marketed as &quot;LED&quot; are actually LCD screens with LED backlighting. True LED screens, which consist solely of diodes, are primarily used in large screens, video walls, and outdoor advertising.<\/p>\n<p> To sum it up<\/p>\n<ul>\n<li> <strong>LCD display<\/strong> It does not light up on its own: liquid crystals act as shutters in front of the light source, i.e. the backlight.<\/li>\n<li> <strong>LED TV<\/strong> \u2014 is an LCD TV in which the outdated CCFL backlight has been replaced with an LED one.<\/li>\n<li> In the strict sense of the word <strong>LED screen<\/strong> (TV, LED wall) consists of diodes that themselves create image pixels.<\/li>\n<li> For home and office use, LCD displays with LED (or OLED) backlighting are usually chosen, while for concerts and outdoor advertising, LED screens are chosen.<\/li>\n<\/ul>\n<h2> How does an LCD screen work?<\/h2>\n<p> <strong>LCD display<\/strong> ( <em>liquid crystal display<\/em> A liquid crystal display (LCD) is a type of display. A layer of liquid crystals is sandwiched between polarizing filters. When voltage is applied, the crystals realign, allowing more or less light to pass through. Color filters separate each pixel into red, green, and blue subpixels.<\/p>\n<p> The key point is that liquid crystals <strong>do not emit light by themselves<\/strong> . A backlight must be located behind the matrix. Previously, this was CCFL fluorescent lamps, but since the early 2010s, LEDs have become dominant. This is where the marketing term &quot;LED TV&quot; comes from.<\/p>\n<h2> \u00abThe &quot;LED&quot; in TV is still LCD.<\/h2>\n<p> When you compare an &quot;LED TV&quot; to an &quot;LCD TV&quot; in a store, you&#039;re essentially comparing two LCD screens with different backlighting. The term &quot;LED TV&quot; is a marketing ploy. The image is still created by a liquid crystal display, and the diodes merely illuminate it. However, the placement of the diodes is crucial:<\/p>\n<ul>\n<li> <strong>Edge LED<\/strong> \u2013 LEDs are located along the edge of the screen. This allows for very thin cases, but backlighting may be uneven.<\/li>\n<li> <strong>Direct LED Backlight \/ Array<\/strong> \u2013 the diodes are arranged in a grid behind the entire matrix, which provides more uniform illumination.<\/li>\n<li> <strong>Local dimming<\/strong> \u2013 The backlight is divided into zones that can be adjusted independently. This makes dark areas of the image darker and improves contrast.<\/li>\n<li> <strong>Mini LEDs<\/strong> - thousands of very small diodes in the backlight, allowing you to create hundreds or even thousands of dimming zones.<\/li>\n<\/ul>\n<p> Another technology is - <strong>OLED<\/strong> . In this technology, each pixel is an organic diode that glows independently and can be completely turned off, eliminating the need for a backlight. Thus, OLED is neither an &quot;LED&quot; in the sense of a screen nor an LCD.<\/p>\n<h2> What is a real LED screen?<\/h2>\n<p> Strictly speaking, <strong>LED screen<\/strong> A LED display is a display whose pixels are made up of light-emitting diodes (LEDs). It uses no liquid crystals or backlighting, as each LED emits its own light of a specific color. These screens are made up of modules, so they can be made in virtually any size and shape.<\/p>\n<p> Their main advantage is <strong>very high brightness<\/strong> : The image is visible even in direct sunlight. Therefore, they are used on billboards, stadiums, concert venues, public transportation, and road information boards. They are also replacing projectors on stages, as they provide higher contrast and allow for the creation of large, seamless video walls.<\/p>\n<p> The clarity of the image on the LED screen is determined <strong>pixel pitch<\/strong> <em>,<\/em> or the distance between the centers of adjacent pixels, measured in millimeters. The smaller the pitch, the denser the image and the closer you can stand without seeing individual diodes. A further development of this technology is <strong>MicroLED<\/strong> , a technology with very small diodes developed by companies such as Samsung, LG and Sony.<\/p>\n<h2> Comparison table of LED and LCD screens.<\/h2>\n<table>\n<tbody>\n<thead>\n<tr>\n<th> Characteristic<\/th>\n<th> LCD TV (also known as LED TV)<\/th>\n<th> LED screen (big screen, LED wall)<\/th>\n<\/tr>\n<\/thead>\n<\/tbody>\n<tbody>\n<tr>\n<td> <strong>Light source<\/strong><\/td>\n<td> Backlight (today LED, previously CCFL)<\/td>\n<td> Each pixel is an LED.<\/td>\n<\/tr>\n<tr>\n<td> <strong>How a painting is created<\/strong><\/td>\n<td> Liquid crystals transmit or block light.<\/td>\n<td> The LEDs light up in the corresponding colors.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Black and contrast<\/strong><\/td>\n<td> Depends on the backlight; local dimming and mini LEDs are better.<\/td>\n<td> High contrast, ability to turn off pixels.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Brightness<\/strong><\/td>\n<td> Suitable for interiors<\/td>\n<td> Very high resolution, readable in the sun.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Size<\/strong><\/td>\n<td> One panel with a certain diagonal<\/td>\n<td> Modules that can be combined into almost any size and shape.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Close-up<\/strong><\/td>\n<td> High resolution in a small space<\/td>\n<td> Depends on the pixel pitch; diodes with a larger pitch can be seen up close.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Typical use<\/strong><\/td>\n<td> TVs, monitors, laptops, smartphones<\/td>\n<td> Outdoor, stadiums, stages, events<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2> LED or LCD screen \u2013 which one to choose?<\/h2>\n<p> <strong>For home and office use<\/strong> The choice comes down to the LCD backlight type (or switching to OLED). If you often watch movies in a dark room, look for a model with full-array backlighting and local dimming or Mini LED. For a bright living room or office, a simpler Edge LED model is suitable. Compare the number of dimming zones and independent test results, not just the word &quot;LED&quot; on the box.<\/p>\n<p> <strong>For events, concerts or advertising<\/strong> , For large-scale displays, especially outdoors and in large venues, LED screens are the best choice. They are bright, modular, and can be customized to suit the stage. Pixel pitch should be selected based on the distance from the audience: a narrow pitch is required for up-close viewing, while a wide pitch is sufficient from a distance. For smaller indoor screens, such as those at exhibitions and conference rooms, LCD monitors or video walls are often sufficient.<\/p>\n<h2> Frequently Asked Questions (FAQ)<\/h2>\n<p> <strong>Is an LED TV the same as an LCD TV?<\/strong><\/p>\n<p> In practice, yes. An &quot;LED TV&quot; is an LCD TV with a backlight made of light-emitting diodes (LEDs). The image is created by a liquid crystal display (LCD), and the LEDs serve only as a light source.<\/p>\n<p> <strong>Which is better: LED or LCD?<\/strong><\/p>\n<p> It all depends on the application. For TVs and monitors, an LCD screen with a good LED backlight (such as a Full Array with local dimming or Mini LED) is better than a model with an older backlight. For large outdoor and stage screens, true LED screens are better due to their brightness and modular design.<\/p>\n<p> <strong>What is the difference between LED and OLED?<\/strong><\/p>\n<p> In an LED TV, the diodes illuminate only the LCD matrix. In an OLED TV, each pixel is an organic diode that illuminates independently and can be turned off completely, ensuring deep blacks and eliminating the need for a backlight.<\/p>\n<p> <strong>How do I know if I have an LCD or LED screen?<\/strong><\/p>\n<p> Check the manufacturer&#039;s specifications for your model. If it says &quot;LED,&quot; &quot;Edge LED,&quot; &quot;Direct LED,&quot; or &quot;Mini LED,&quot; it&#039;s an LCD display with an LED backlight. Manufacturers label OLED displays separately.<\/p>\n<p> <strong>What is pixel pitch in LED display?<\/strong><\/p>\n<p> This is the distance between the centers of adjacent pixels, measured in millimeters. A smaller distance means a sharper image at close range and, as a rule, a higher price for the screen.<\/p>\n<h2> See also<\/h2>\n<ul>\n<li> What&#039;s the difference between Netflix packages?<\/li>\n<li> What is the difference between MP3 and MP4?<\/li>\n<li> What is the difference between a mobile phone and a smartphone?<\/li>\n<li> What is the difference between digital printing and offset printing?<\/li>\n<li> What is the difference between OLED and QLED?<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>An LCD screen creates an image using liquid crystals, which either allow or block light from the backlight.
