2.01 Compare and contrast the display components of mobile devices

  • LCD (Liquid Crystal Display)

  • A type of display technology where liquid crystals change properties with applied voltage to display images. Used in most mobile device screens.

  • TN LCD (Twisted Nematic Liquid Crystal Display)

  • A type of LCD with fast response times to reduce motion blur but limited color accuracy and narrow viewing angles.

  • IPS LCD (In-Plane Switching Liquid Crystal Display)

  • A type of LCD with better color reproduction and wide 178/178-degree viewing angles, suitable for graphics and design work.

  • VA LCD (Vertical Alignment Liquid Crystal Display)

  • A type of LCD offering a wide color gamut and high contrast ratios but with slower response times and narrower viewing angles compared to IPS.

  • LED Backlit Display

  • A display screen illuminated by LED arrays, usually edge-lit with a diffuser for even brightness. Replaces older CCFL backlighting technology.

  • OLED (Organic LED)

  • A display technology using organic compounds that emit light per pixel, providing excellent contrast, lower power consumption, and the potential for flexible screens.

  • Digitizer

  • A layer in a display that converts touch inputs into digital signals using a grid of sensors.

  • Capacitive Digitizer

  • A type of digitizer that detects touch through a grid of sensors and supports multitouch gestures like "pinching" and "swiping" to provide a responsive and interactive user experience.

  • Screen Protection

  • The topmost layer of the display made from scratch-resistant and shock-resistant tempered glass (e.g., Gorilla Glass) to protect the screen from damage.

  • Haptic Feedback

  • Technology integrated with digitizers to provide tactile sensations in response to touch inputs, enhancing the realism of the interaction.

  • Rotating and Removable Screens

  • Screens that can rotate, flip, or detach from the keyboard in hybrid devices, allowing for flexible use as both a laptop and a tablet.

  • Accelerometers and Gyroscopes

  • Sensors used in mobile devices to detect changes in orientation, enabling automatic screen rotation and other functionalities like motion controls in games.

  • Burn-in

  • A phenomenon where static images leave permanent marks on displays, often due to prolonged display of the same image.

  • Viewing Angles

  • The angles at which a display can be viewed clearly without color distortion or loss of brightness.

  • Contrast Ratio

  • The ratio between the luminance of the brightest white and the darkest black a display can produce.
