A field technician is servicing multiple laptop displays presenting with distinct operational characteristics and hardware failures. Match each laptop display component on the left with its correct architectural function or diagnostic symptom on the right.
- Inverter BoardConverts low-voltage DC power to high-voltage AC power for CCFL backlights; failure causes an extremely dim screen visible only with external illumination.
- DigitizerTranslates analog tactile contact on the display surface into digital input signals for processing by the operating system.
- OLED PanelEmits light directly on a per-pixel basis without requiring a separate backlight assembly or high-voltage power board.
- Wi-Fi Antenna HarnessRoutes micro-coaxial wires through the display hinge to the upper bezel to optimize radio frequency reception and transmission.
Cevap
Inverter Board matches the component that converts low-voltage DC to high-voltage AC for CCFL backlights. Digitizer matches the component that translates tactile surface contact into digital input signals. OLED Panel matches the self-emissive pixel technology that operates without a separate backlight. Wi-Fi Antenna Harness matches the micro-coaxial wiring routed through the hinge to the upper bezel for wireless signal coverage.
Each display component serves a distinct physical or electronic function within a mobile device chassis: inverters convert low-voltage DC to high-voltage AC for CCFL backlights; digitizers capture analog touch gestures to output digital signal data; OLED panels use self-emitting pixels eliminating backlights; and Wi-Fi antenna harnesses run through the hinges to elevate the RF elements inside the bezel.
