A see-through display or transparent display is an electronic display that allows the user to see what is shown on the screen while still being able to see through it. The main applications of this type of display are in head-up displays , augmented reality systems, digital signage, and general large-scale spatial light modulation .
Samsung’s microLED display technology transfers micrometer-scale LEDs into LED modules, resulting in what resembles wall tiles composed of mass-transferred clusters of almost microscopic lights. [95] [96] Samsung's Transparent MicroLED (debuted at 2024 CES) Samsung has also debuted at 2024 CES their Transparent MicroLED display. [97]
Detail view of an LED display with a matrix of red, green and blue diodes The 1,500-foot (460 m) long LED display on the Fremont Street Experience in Downtown Las Vegas, Nevada, is currently the largest in the world. A LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) as pixels for a video display.
First Generation—Use a CRT to generate an image on a phosphor screen, having the disadvantage of the phosphor screen coating degrading over time. The majority of HUDs in operation today are of this type. Second Generation—Use a solid state light source, for example LED, which is modulated by an LCD screen to display an image. These systems ...
CRTs use an electron beam, scanning the display, flashing a lit image. If interlacing is used, a single full-resolution image results in two "flashes". The physical properties of the phosphor are responsible for the rise and decay curves. Plasma displays modulate the "on" time of each sub-pixel, similar to DLP.
In spite of LCD's dominance of the television field, other technologies continued to be developed to address its shortcomings. Whereas LCDs produce an image by selectively blocking a backlight, organic LED, microLED, field-emission display and surface-conduction electron-emitter display technologies all produce an illuminated image directly. In ...
Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market ...
Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities. [31] Samsung sells a luxury and commercial product called "The Wall", which consists of several microLED display modules tiled together, like in most video walls.
