A technician is inventorying internal sub-assemblies across various modern and legacy laptop screens. Match each laptop display component on the left with its correct operational description on the right. Which pairs correctly match each component to its function?
- Inverter Board AssemblySupplies high-voltage alternating current to power fluorescent backlight lamps in older LCD displays.
- Touch Screen Digitizer LayerOverlay panel that converts tactile contact into spatial coordinate data for input processing.
- Self-Emissive OLED Display PanelUses individual self-illuminating pixels to display images without requiring an independent backlight unit.
- Internal Wireless Antenna WiresConductive cables routed along the top of the display enclosure to maintain high wireless signal strength.
Cevap
Inverter Board Assembly matches high-voltage AC power supply for fluorescent backlights; Touch Screen Digitizer Layer matches converting tactile contact to spatial coordinates; Self-Emissive OLED Display Panel matches individual self-illuminating pixels without backlights; Internal Wireless Antenna Wires match conductive cables routed along the screen enclosure.
Each laptop display component serves a distinct role: Inverter boards convert low-voltage DC to high-voltage AC for CCFL backlights; digitizers capture touch input as digital coordinate data; OLED displays illuminate natively per pixel without backlighting; and wireless antenna wires are routed high into the screen bezel for optimal RF reception.
