LCDs are one of the most common types of electronic displays used today. They work by manipulating the orientation of liquid crystals to control the amount of light passing through. LCD displays are thin, lightweight and consume very little power compared to other display technologies. They are used in televisions, computer monitors, mobile phones, tablets, laptops and other portable electronic devices due to their energy efficiency and compact design. LCD panels come in a variety of sizes ranging from small displays found in devices like smart watches to very large panels used in television sets.
Active Matrix LCD (AMLCD)
AMLCDs use an active matrix backlight system made of thin-film transistors to improve image quality and response time over passive matrix displays. Each pixel is controlled individually for faster switching and better picture quality. This makes AMLCDs ideal for displays that require higher resolutions and faster refresh rates like HDTVs and computer monitors. While more expensive to produce than standard LCDs, AMLCDs deliver sharp, vibrant and life-like images.
Organic Light Emitting Diode Displays (OLEDs)
OLED technology uses thin films of organic materials placed between two conductors that emit light when electric current is applied. They provide better contrast, deeper blacks and higher brightness compared to LCDs due to their ability to illuminate individual pixels. OLED displays are also thinner, more flexible and consume less power. Mobile devices have largely adopted OLED displays in recent years due to their thinner profile and energy efficiency. As production costs decline, OLEDs are expected to replace LCD technology in televisions and computer monitors as well.
Plasma Display Panels (PDPs)
Electronic displays create images using small cells containing electrically charged gas (plasma). When energized, the gas emits photons to produce images across millions of color-emitting pixels. PDP screens were popular as large-screen televisions due to their thin designs and superior brightness but have now been mostly replaced by LCD and OLED panels. They still find some use in specialized industrial and commercial applications requiring durable, high-definition screens.
Cathode Ray Tube (CRT) Displays
CRT displays were common in old televisions and computer monitors but have fallen out of favor due to limitations like bulkiness, high power consumption and image quality issues compared to newer technology. In a CRT, an electron beam is shot from the back of the screen to illuminate color-emitting phosphor dots, creating images. Improved LCD and PC monitor technologies made CRT screens obsolete for most consumer applications by the early 2000s. However, they remain indispensable for specialized industrial and scientific equipment like oscilloscopes due to their high refresh rates and resolution capabilities.
Advantages of Electronic Displays
Versatility
Electronic displays offer versatility by coming in a wide range of sizes and form factors suitable for diverse applications. From tiny screens in smartwatches and calculators to jumbotron displays spanning multiple stories, electronic displays can scale to fit any space or product. Mobile devices in particular demonstrate versatility through folding and flexible designs enabled by new display technologies.
Portability
Electronic displays have enabled entirely new classes of portable devices and boosted mobility. Thin, lightweight screens in laptops, tablets, smartphones and e-readers support on-the-go productivity and entertainment. Their low energy consumption also allows extended use away from power outlets. In contrast, bulky CRT monitors severely limited portability before the introduction of advanced flat panel displays.
Customization
Electronic displays are highly customizable through touchscreens, stylus input and interactive interfaces. Beyond static images, they can be programmed to display customized menus, apps and live content tailored for individual users and applications. Touch capabilities in particular have revolutionized how people interact with technology.
Long Lifespan
Well-maintained electronic displays last considerably longer than their predecessors. Modern LCD, OLED and LED panels are rated for 50,000+ hours of use versus 10,000-15,000 hours for CRT monitors. They are more durable against physical shocks as well. Displays remain functional for 5-10 years or longer when handled with care.
Constant Innovation
There has been tremendous ongoing innovation in display technologies to deliver improvements like thinner designs, higher resolutions, wider color gamuts, faster refresh rates and new form factors. New manufacturing methods and materials constantly push display capabilities forward, powering innovation across consumer electronics and other industries.
Applications of Electronic Displays
Televisions
Displays are essential for televisions to visualize broadcast content, streaming video and more. Advances like 4K/UHD, HDR, OLED and large panel sizes have transformed the home TV experience.
Computers
Computer monitors and laptop screens bring the digital world to life through high fidelity color reproduction and interaction with OS interfaces, programs and documents.
Mobile Devices
Smartphones, tablets, smartwatches and other portable tech rely entirely on vibrant, high-res display panels for apps, photos, videos and connectivity. folding displays are expanding design horizons.
Industrial Applications
Process controls, medical imaging equipment, avionics, digital signage and more utilize specialized displays optimized for mission-critical viewing in challenging environments.
Gaming
Cutting-edge monitors, TVs and handheld displays deliver immersive visuals enhanced by features like high refresh rates and low latency for the best gaming experiences.
Transportation
Vehicle dashboards, infotainment systems and public transit displays keep passengers informed through all manner of electronic signage.
