Differences Between LCD and LED

Differences between LCD and LED play a big role for people when they consider purchasing gadgets. Furthermore, many brands use the LCD vs LED factor to good use when marketing their products. Technically speaking, both LCD and LED televisions happen to be liquid crystal displays. Keep on reading to clearly understand the differences between LCD and LED.

Definition of LCD

A liquid crystal display or LCD refers to a combination of the solid state of matter and the liquid state to produce display effect. LCD uses a liquid crystal to cause the formation of a visible image. Liquid crystal displays are display screens that implement a super-thin technology display technology.

Definition of LED

A light-emitting diode (LED) refers to a semiconductor device that emits light when the passing of electric current takes place through it. Furthermore, the production of light in LED happens when current-carrying particles combine together within the semiconductor material. Moreover, one can describe LED as solid state devices because the generation of light takes place within the solid semiconductor material.

Differences between LCD and LED

Important differences between LCD and LED are below

Parameter	LCD	LED
Response Time	LCD is slower in comparison to LED when it comes to response time	LED is better than LCD when it comes to response time
Power Consumption	LCD consumes lesser power than LED	LED consumes more power than LCD
Cost	Generally less costly	Generally more costly
Picture Quality	LCD has good picture quality but not as good as LED	LED offers superior picture quality
Black Level	LCD has inferior black level in comparison to LED	LED certainly have better black level
Colour Accuracy	LCD has good colour quality but it is certainly below the level of LED	Offers more enhanced colour quality
Viewing angle	The wide angle in LCD decreases by 30 degrees from the centre	LED has a viewing angle that is wider than LCD

More Details About LCD

Liquid crystal display(LCD) has several layers that have electrodes and two polarized panel filters. Furthermore, the use of LCD technology takes place for displaying the image in electronic devices like computers etc. Moreover, the projection of light is from a lens on a layer of liquid crystal.

The combination of a grayscale image with colour light results in the formation of the colour image. Afterwards, the display of such an image takes place on the screen. An LCD is made from a passive display grid or an active matrix display grid. The LCD smartphones consist of the active-matrix display.

Liquid crystal display (LCD) screen works by blocking light instead of emitting light. Moreover, LCD needs backlight as it cannot emit light. Furthermore, LCD displays are quickly replacing the cathode ray tube. This is because; cathode ray tube uses more energy in comparison to LCDs, besides being heavier.

More Details About LED

The LED is a PN-junction diode that tends to emit light when the passing of electric current takes place through it in a forward direction. Furthermore, a charge carrier recombination happens in LED.

A combination of electrons belonging to N-side and P-side takes place in LED. Due to this, the formation of energy takes place in the form of heat and light. The LED comprises semiconductor material that is certainly colourless, and the radiation of light happens through the diode’s junction.

Extensive use of LEDs takes place in segmental matrix displays, as well as dot matrix displays, of numeric character and alphanumeric character. Moreover, experts use LED for single line segment while for making the decimal point single.

FAQs about LCD and LED

Question no 1: Explain the difference between LCD and LED in computer graphics?

Answer 1: The difference LCD and LED in computer graphics is that LED offers far more superior graphics in comparison to LCD. This is because; LED uses PN-Junction diode which significantly enhances computer graphics. In contrast, LCD uses liquid plasma or crystal for light emission.

Question 2: Differentiate between LCD and LED in terms of the response time?

Answer 2: When it comes to response time, LED is certainly faster on comparing it with LCD
