Display Modules can be any technology that supports the visual sense of an input signal. These devices are frequently put together with computer systems and other electronic machines. Liquid crystal display (LCD), light-emitting diode (LED), or organic light-emitting diode (OLED) technology provides the foundation for the majority of "flat panel" displays. Flat panel displays have a maximum resolution, which establishes how many pixels are present overall. The most popular display resolutions are 3840 x 2160 (4K) or 1920 x 1080 (1080p). Most flat-panel televisions have a widescreen aspect ratio of 16:10 or 16:9. Numerous cable formats, such as component video, composite video, VGA, DVI/HDMI, and DisplayPort, can be used to power flat panel displays.
Differences Among Display Modules LCD, LED, and OLED
Major differences found in these Display Modules are as follows:
- Display Module LCD & LED - Liquid Crystal Display abbreviated as LCD is a flat-screen display technology typically used in computer monitors and televisions (TVs). This technology can also be seen on the screen of mobile devices, like tablets, smartphones, and laptop computers. In addition to looking different than clunky Cathode Ray Tube (CRT) monitors, LCD screens also perform very differently.
- LCD and LED monitors both use liquid crystals to produce an image, but the main difference is in their backlights. LCD monitors use fluorescent backlights, while an LED monitor uses light-emitted diodes for its backlight. An LED monitor generally has enhanced image quality, but it can differ in its backlight structure.
- Display Module OLED - The term Organic Light-Emitting Diodes, abbreviated as (OLEDs) is a technology that makes use of LEDs and emits light made of organic molecules instead of using conventional means. The best display panels in the world are thought to be made with these organic LEDs.
- OLEDs allow for emissive displays, in which each pixel is individually controlled and generates its own light (unlike LCDs in which the light comes from a backlighting unit). OLED displays have excellent visual quality, including vivid colours, quick motion, and most significantly, a high contrast ratio.
Uses of Display Module - LCDs, LEDs & OLEDs
Liquid crystal display LCDs are typically found in several electronic devices such as camcorders and digital cameras, electronic billboards, computer monitors, video projection systems, and flat panel televisions.
While light-emitting-diodes (LEDs) and organic light-emitting-diodes OLEDs are advanced technology that gives a visualisation of ultra-definition and 4k image quality, LED techniques are commonly utilized in:
- Intruder Alarms & Traffic flow Signals
- Aeronautics Illumination
- Motorized heat lamps & Camera Flashes
- Calculators and Digitized Computers
- Multiplexers and Microchips
- Digital Wristwatches & Motion Picture Phones
In addition, OLED technology can be found in electronic devices that offer extreme-quality displays where high readability and reliability are required, such as:
- Handheld Electronic Systems like Android, and iOS Smartphones, as well as Media Players
- Digital Photographic Camera
- High-end TV Systems and Mini Screens
- Movable Gaming Consoles
- OLED Computer Monitors
