  • Define and describe LCD
    Liquid Crystal Display, uses electric impulses to rotate polarized liquid crystals
  • List 3 advantages of LCD displays
    Lightweight, relatively low power consumption, relatively inexpensive
  • List 3 disadvantages of LCD displays
    No true blacks, requires a backlight, backlights are difficult to replace
  • List the 3 types of LCD displays
    TN (Twisted Nematic), IPS (In Plane Switching), VA (Vertical Alignment)
  • Name 1 advantage and 2 disadvantages of TN
    Fast response times, poor viewing angles, poor color representation
  • Name 1 advantage and 1 disadvantage of IPS
    Excellent color representation, more expensive
  • How does VA compare to TN and IPS
    It is a good compromise between the two
  • Define and describe OLED
    Organic Light Emitting Diode, uses an organic compound which emits light while electrified
  • Why might one prefer OLED to LCD
    Thinner, lighter, no backlight, best color representation, true blacks
  • True or false: OLED is more expensive than LCD
    True
  • Where is one most likely to find the wireless antennas on a laptop?
    Near the top of the display case
  • What typically connects through the hinges on a laptop?
    The wireless antennas connections
  • Define and contrast LED vs CCFL backlighting
    Light Emitting Diode vs Cold Cathode Fluorescent Light, LEDs are more energy efficient and versatile and used to be more expensive than CCFL but are now priced similarly, most modern laptops use LED backlighting
  • What is an inverter?
    A device that converts DC power into AC power
  • Why might a laptop have an inverter?
    Some backlights run on AC power, particularly CCFL
  • What is a digitizer?
    A device that translates physical touch into digital input
  • What is a touch screen?
    A display with an integrated digitizer
