Which of the following statements are true regarding Organic Light Emitting Diode (OLED)? 1. An OLED display works without a backlight thus consumption of energy is less than LCD. 2. In low ambient light conditions, an OLED screen has lower contrast ratio than LCD. 3. It produces brighter light and has a wider viewing angle. Select the correct answer using the codes given below: |ForumIAS

[A] 1 and 2

[B] 2 and 3

[C] 1 and 3

[D] All

Answer: C

Notes:

Explanation: Organic Light Emitting Diode:

An OLED is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.
This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent.
OLEDs are used to create digital displays in devices like television screens, computer monitors, and portable systems like mobile phones, handheld game consoles and PDAs.
An OLED display works without a backlight; thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD) and consume less energy.
In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.
It produces brighter light using less energy as compared to LEDs.
