Which of the following pairs of acronym and its expansion are incorrectly matched?
ALED, Light Emitting Diode
BCRT, Cathode Ray Tube
CLCD, Liquid Control Display ✓ Correct
DVDU, Video Display Unit
Correct answer: (C) LCD, Liquid Control Display — LCD is incorrectly matched, so that is the answer.
Explanation
★LCD is incorrectly matched, so that is the answer.
★LCD actually stands for Liquid Crystal Display, not Liquid Control Display.
★It is a flat panel display that uses the light modulating properties of liquid crystals.
★LED, meaning Light Emitting Diode, is expanded correctly.
★CRT, meaning Cathode Ray Tube, and VDU, meaning Video Display Unit, are also correct.
★So only the LCD expansion is wrong.
