Which of the following statements are correct with reference to Organic Light-Emitting Diodes (OLEDs)?
(A). Because of plastic organic layers, OLEDs are much thicker and heavier than conventional LCD/LED formats.
(B). OLEDs give a brighter light than LEDs leading to more vivid colours.
(C). OLEDs produce a much larger field of view than LCD/LED formats.
(D). OLEDs require some form of back-lighting so that the screen can be lit up.
(E). OLEDs consume more power than LCD/LED formats and thus produce more heat.
Choose the correct answer from the options given below:
Answer: D. (B) and (C) only — OLEDs are self-emissive devices, meaning they do not require a backlight unit (refuting D). Consequently, they are thinner and lighter than LCD/LED formats…

Show answer & explanation
Correct answer: D
OLEDs are self-emissive devices, meaning they do not require a backlight unit (refuting D). Consequently, they are thinner and lighter than LCD/LED formats (refuting A). OLEDs provide significantly wider viewing angles compared to LCD/LED technologies, making statement C correct. They also offer better color saturation and brightness relative to standard LCDs, supporting statement B. Statement E is incorrect as OLED efficiency varies but they do not inherently consume more power or produce more heat than LCDs in typical usage. Therefore, statements B and C are the correct assertions.
