Display – TV's
LCD (Liquid Crystal Display)
- Uses a backlight (usually LED) to illuminate liquid crystals.
- Affordable and widely available.
- Comes in three main panel types: TN, IPS, and VA (VA is most common in TVs).
- Best for: Budget-friendly buyers, general use.
LED (Light-Emitting Diode) - A Type of LCD
- Uses LED backlights instead of older CCFL backlights.
- Edge-lit LED: LEDs are on the edges, making the TV thinner.
- Full-array LED: LEDs are spread across the entire screen for better brightness and contrast.
- Best for: Budget-conscious buyers who want good quality.
QLED (Quantum Dot LED) - An Enhanced LED TV
- Uses a quantum dot layer to improve brightness and color.
- Still uses an LED backlight (not self-emissive like OLED).
- Best for: Bright rooms, vivid colors, and affordability compared to OLED.
OLED (Organic Light-Emitting Diode)
- Each pixel emits its own light (no backlight).
- Perfect blacks, infinite contrast, and superior viewing angles.
- Cons: Expensive and has a risk of burn-in (static images staying too long).
- Best for: Movie lovers, dark-room viewing, high-end gaming.
QD-OLED (Quantum Dot OLED)
- A hybrid of QLED and OLED for brighter colors and better HDR.
- Newer than OLED and improves on brightness limitations.
- Best for: High-end users who want OLED but with better brightness.
Mini-LED (Advanced LED TV)
- Uses thousands of tiny LEDs for improved brightness and contrast.
- Better than standard LED but not as good as OLED.
- Best for: Bright rooms, HDR content.
Micro-LED (Next-Gen Display)
- Similar to OLED but uses microscopic LEDs for each pixel (no backlight).
- Brighter and longer-lasting than OLED, with no burn-in issues.
- Cons: Extremely expensive and rare.
- Best for: Future premium buyers.
Plasma (Older Technology - Discontinued)
- Deep blacks and smooth motion but heavy and power-hungry.
- Discontinued in favor of OLED and LED.
Display – Touch Screens
LCD (Liquid Crystal Display)
- Uses a backlight to illuminate pixels.
- Good brightness but lower contrast compared to OLED.
- Common in budget and mid-range phones.
Variants
- TFT (Thin Film Transistor): Older, less efficient.
- IPS LCD (In-Plane Switching): Better colors and viewing angles.
Pros & Cons
- Affordable, good brightness in sunlight.
- Less vibrant colors, lower contrast.
Examples :
- Older iPhones (before iPhone X), some budget Android phones.
OLED (Organic Light-Emitting Diode)
- Each pixel emits its own light (no backlight needed).
- Perfect blacks, high contrast, and vibrant colors.
- More power-efficient for dark themes
Pros & Cons
- Excellent colors, deep blacks, energy-efficient.
- More expensive, risk of burn-in (rare in modern models).
Examples :
- iPhone 12 and later, Samsung Galaxy S series, Pixel phones.
AMOLED (Active Matrix OLED) - A Type of OLED
- mproved version of OLED with better energy efficiency and faster response times.
- Super AMOLED (by Samsung): Integrated touch layer for thinner, more responsive screens.
Pros & Cons
- Deep blacks, high contrast, energy-efficient.
- Higher cost than LCD.
Examples :
- Samsung Galaxy S & Note series, OnePlus flagship phones.
Dynamic AMOLED / LTPO AMOLED (Advanced OLED)
- Dynamic AMOLED: Enhanced HDR support and better eye comfort.
- LTPO (Low-Temperature Polycrystalline Oxide): Allows adaptive refresh rates (e.g., 1Hz–120Hz for battery savings).
Examples :
- Samsung Galaxy S21 Ultra+, iPhone 13 Pro and newer.
P-OLED (Plastic OLED)
- OLED screen with a plastic substrate instead of glass, making it flexible.
- Used in foldable phones and curved displays.
Examples :
- Motorola Razr, Samsung Galaxy Z Fold & Flip.
Mini-LED (Rare in Phones)
- Uses thousands of tiny LEDs for better brightness and contrast than LCD.
- Not as power-efficient as OLED.
Examples :
- Some gaming phones and tablets (like iPad Pro)
Micro-LED (Future Technology)
- Similar to OLED but even brighter and more efficient.
- No risk of burn-in.
- Still expensive and rare in smartphones.
Future Use :
- May replace OLED in premium phones.
Display – Touch Screens
Resistive Touchscreen
- Two flexible layers with a gap between them.
- When pressed, the layers make contact, registering the touch.
- Works with fingers, styluses, or gloves.
- Cheaper than capacitive touchscreens.
- Requires pressure to register touch.
- Less responsive and lower clarity than capacitive screens.
Used In :
- Older phones, ATMs, industrial devices.
Capacitive Touchscreen (Most Common in Smartphones)
- Uses a transparent conductive layer.
- A touch disrupts the electrical field, registering the input.
- Highly responsive and supports multi-touch gestures.
- Brighter and clearer than resistive screens.
- Doesn’t work with most gloves or non-conductive objects.
- More expensive than resistive screens.
Used In :
- Smartphones, tablets, modern laptops.
Infrared (IR) Touchscreen
- Uses infrared LEDs and sensors to detect touch.
- When an object interrupts the infrared beams, the touch is detected.
- Works with any object (finger, glove, stylus, etc.).
- No physical screen layer, making it highly durable.
- Can be affected by dust, sunlight, and water.
- More expensive than capacitive and resistive screens.
Used In :
- Interactive kiosks, industrial displays, medical equipment.
Surface Acoustic Wave (SAW) Touchscreen
- Uses ultrasonic sound waves across the screen.
- A touch absorbs part of the waves, registering the input.
- Very accurate and durable.
- Works with fingers, styluses, or gloves.
- Can be affected by dust and water.
- Expensive and not commonly used in smartphones.
Used In :
- Medical displays, kiosks, industrial applications.
Optical Touchscreen
- Uses cameras and infrared sensors to track touch points.
- Can detect multiple touches at once.
- Works with fingers, gloves, or styluses.
- Can be affected by ambient light.
- Bulky and not suitable for slim devices.
Used In :
- Large interactive displays, conference room screens.
In-Display Fingerprint Touchscreen (Advanced Capacitive/Optical/Ultrasonic)
- Some modern screens have built-in fingerprint sensors for security.
- Optical Sensors use light to scan the fingerprint.
- Ultrasonic Sensors use sound waves for 3D fingerprint mapping (more secure).
Used In :
- High-end smartphones (Samsung Galaxy S series, OnePlus, Xiaomi).
