Question
- Which mobile device screen technology uses no backlight?A. BYODB. LCDC. LEDD. OLED
Solution
The mobile device screen technology that uses no backlight is D. OLED.
Here's why:
OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs are emissive displays that do not require a backlight and so are thinner and more efficient than LCD displays (which do require a white backlight).
