Difficulty: EasyLaptop Display Components and Features

A technician is servicing a modern laptop equipped with an organic light-emitting diode (OLED) display screen. Which TWO of the following hardware components are typically housed within or routed through the laptop display bezel assembly? (Select TWO.)

  1. Wi-Fi antenna harness cablesAnswer
  2. Integrated webcam moduleAnswer
  3. C
    High-voltage fluorescent inverter board
  4. D
    SO-DIMM system memory module
  5. E
    NVMe M.2 solid-state drive

Answer

Wi-Fi antenna harness cables and the integrated webcam module are the components located inside or routed through the display bezel assembly.
The upper display housing of a laptop typically contains the display panel itself, the integrated webcam module positioned in the upper bezel, and the Wi-Fi antenna harness routed along the screen edges to provide maximum wireless range.

Step-by-Step Solution

1
Identify the components housed within a laptop's upper display assembly.
Components in the display assembly include the display panel, digitizer (if touch-enabled), webcam/microphone array, and wireless antenna leads.
Antennas are placed high in the display lid for maximum signal range, and webcams align with user sightlines at the top of the bezel.
2
Differentiate OLED display architecture from legacy LCD displays.
OLED displays use emissive pixels and do not use a separate backlight or backlight inverter board.
Inverter boards are only used in older CCFL LCD screens to convert DC power to AC for fluorescent tubes.
