A desktop support technician is reviewing component characteristics for modern laptops and mobile devices before performing hardware servicing. Which of the following statements regarding mobile display and battery components are correct? (Select TWO.)
- OLED displays emit their own light at the pixel level and do not require a separate backlight inverter board.Cevap
- Physically swollen lithium-ion batteries must be carefully removed and safely recycled rather than subjected to calibration routines.Cevap
- CDimming issues on modern OLED laptop screens are usually resolved by replacing the fluorescent backlight inverter.
- DRepeated deep discharge cycles should be performed to recalibrate and restore physically swollen laptop batteries.
Cevap
OLED displays emit their own light at the pixel level without requiring a separate backlight inverter board, and physically swollen lithium-ion batteries must be safely removed and recycled rather than calibrated.
OLED panels rely on self-emissive organic light-emitting diodes for illumination, making backlights and inverter boards unnecessary. Additionally, swollen lithium-ion batteries are damaged components that present a risk of fire or leakage, making immediate, safe removal and recycling mandatory.
