Which of the following statements are correct with reference to Organic Light-Emitting Diodes (OLEDs)? Choose the correct answer from the options given below.

1.Because of plastic organic layers, OLEDs are much thicker and heavier than conventional LCD/LED formats

2.OLEDs give a brighter light than LEDs leading to more vivid colours

3.OLEDs produce a much larger field of view than LCD/LED formats

4.OLEDs require some form of back-lighting so that the screen can be lit up

5.OLEDs consume more power than LCD/LED formats and thus produce more heat

A1, 2 and 3 only

B2, 3 and 5 only

C3, 4 and 5 only

D2 and 3 only ✓ Correct

Correct answer: (D) 2 and 3 only

Explanation

Statement 2 is correct because OLEDs give brighter, more vivid colours than ordinary LEDs.

Statement 3 is correct because OLEDs offer a much wider viewing angle than LCD or LED panels.

Statement 1 is wrong since the thin organic layers make OLEDs thinner and lighter, not thicker.

Statement 4 is wrong because each OLED pixel emits its own light and needs no back lighting.

Statement 5 is wrong since OLEDs generally use less power and produce less heat.

Being self emissive, OLEDs can switch pixels fully off for true blacks.
