Display Technologies
Monitor types and display standards.
Display technologies are central to modern computing, playing a key role in how users interact with digital content. Various types exist: 1. LCD (Liquid Crystal Display): Uses liquid crystals that twist and untwist to control light passage. Two main types include TN (Twisted Nematic) panels offering fast response times but limited viewing angles, and IPS (In-Plane Switching) providing superior color accuracy and wider viewing angles. 2. LED (Light-Emitting Diode): Actually an LCD display using LED backlighting rather than traditional CCFL (Cold Cathode Fluorescent Lamp) backlights. Advantages include thinner panels, better energy efficiency, and improved brightness. 3. OLED (Organic Light-Emitting Diode): Individual pixels produce their own light, eliminating the need for backlighting. This enables true blacks, infinite contrast ratios, and extremely thin displays. 4. QLED (Quantum Dot LED): Uses quantum dot technology to enhance color and brightness in LCD panels. 5. Plasma: Once popular for large screens, uses small cells of ionized gas (plasma) to create images. Resolution standards include: - HD (1280×720) - Full HD (1920×1080) - QHD/2K (2560×1440) - 4K/UHD (3840×2160) - 8K (7680×4320) Other important specifications include: - Refresh rate: Measured in Hertz (Hz), indicates how many times per second the display updates - Response time: Measured in milliseconds (ms), indicates how quickly pixels can change color - Contrast ratio: The difference between the brightest white and darkest black - Color gamut: Range of colors the display can reproduce - Aspect ratio: The proportional relationship between width and height (16:9 being standard) For connectivity, modern displays typically feature HDMI, DisplayPort, USB-C, and occasionally legacy VGA or DVI connections.
