LEDs, on the other side, emit light in one direction because of the PN-junction diode. LCDs emit light in all directions that allow users to easily watch the displayed content from different angles.LCDs have a better wide viewing angle as compared to LEDs.LEDs are comparatively more power-efficient than LCDs.The higher the number of pixels, the better the resolution and the quality of the picture. In terms of the resolution, LED provides more pixels on the screen than LCD.LCD uses liquid filaments filled between glass-electrodes that help emit the light, whereas LED uses the PN-junction diode concept, which is forward biased for the light's emission.The repair cost is high because LED parts are costly and tough to find according to the suitable product model.įew key differences between LCD and LED are listed below:.LED has a limited range of wide viewing angles.
The higher the screen-size, the more it will cost. LED usually lasts longer, making it long-life durable.Ī few essential dis-advantages of the LED are listed below:.Advantages of LEDįew essential advantages of the LED are listed below: But these TVs have a truer white display when compared with the backlit fluorescent LED TVs. Note: The dimming capability feature is usually unavailable in edge-lit LED TVs. Typically, this technique makes lights darker and blocks extra lights passing through the screen panel. LEDs work with a dimming capability with the backlighting that makes pictures truer black.This eventually helps achieve clearer, sharper, and natural colors. LEDs operate with the color wheel technique or distinct RGB-colored light.There are two main reasons why LEDs have better quality pictures: In LEDs, the light-emitting diodes can be placed either behind the screen panel or around the edges. This diode mechanism in LEDs produces better and sharper pictures than the general LCDs. These diodes are usually referred to as the semiconductor light sources that produce lights when a current passes through them. However, it differs from LCD because the LCDs use fluorescent lights while LEDs use light-emitting diodes. LCD can provide weak or bad pixels, resulting in varying intensity or shading on the screen.Īn LED (short for ' light-emitting diode') is a subset of LCD, which technically uses liquid crystal displays.LCD is built with a fixed aspect ratio and a resolution.White saturation in LCD sometimes leads to an uneven brightness.LCD is not good in low-light or dim light environments because it has difficulty producing black and dark grays light.The most common disadvantages of the LCD are highlighted below: LCD is light-weight than old CRT displays.Advantages of LCDįew essential advantages of the LCD are listed below: Because LCDs are comparatively thinner than casual backlit TVs, they have angle-viewing and anti-glare issues. But it is important to note that the molecules are not fixed in any particular shape or form. Besides, the molecules are arranged in fixed patterns. The liquid crystal material used in LCDs is neither a liquid nor a solid however, it consists of properties similar to the crystallized solid. This eventually helps to emit visible lights. A liquid crystal filament is filled between the transparent electrodes, and the current is passed through it to energize the filaments. LCD produces the contents on the screen in the form of a dot matrix or segments. The lights are always placed behind the screen panel. Instead of its lights, LCD uses fluorescent tubes that help produce the lights and lighten the picture. Let's first discuss both with the definitions: What is the LCD?Īn LCD (short form of ' liquid crystal display') is a passive device with no lights to display text or media. This will also help us understand which one should be considered when purchasing any product based on LCD and LED. In this article, we are explaining the significant differences between LCD and LED, which will help us know the usage and benefits of both. Although they both are used in many similar products, there are noticeable differences based on various factors.
It is important to note that they are not similar and cannot be used interchangeably. LCD and LED both are very co-relevant, and that is why most people get confused between them. Next → ← prev Difference between LCD and LED
