LCD vs LED TV

LCD vs LED TV – if You are Still Confusing the Two Types

By

When TV was first becoming a platform offering a long enough and broadspread enough broadcast capability to make owning one worthwhile, options were almost non-existent, with a big contraption of a box that housed all the necessary components to make it work properly. And then the final product–the “viewing window” sat positioned at the top front of the console, and if the LCD vs LED TV was not turned on and you didn’t know what you were looking for, you might have altogether missed it.

The whole thing looked more like a big piece of strange furniture, but once turned on, that tiny screen would find any and all humans within range gathered all around it. There, they would sit and stand, totally transfixed upon the very small black, grey and white images as they moved about and talked, much in the same way they would have done had they been there in the room, but only shrunken down and mostly colorless.

It’s hard to try to envision what it was like to experience those first days of live LCD vs LED TV transmission. Surely it seemed to viewers everywhere to be the closest brush with magic any of them had ever experienced.

Time to Catch On

As the years went by, more viewing choices were made available as bit by bit, TV broadcasting was becoming a very viable industry and means of keeping up with a wide variety of news stories and entertainment venues. Now, looking back, those pioneering transmissions were probably so very limited and without range, especially in contrast to the zillions of channels we have from which to choose these days.

Still, for very many years, the only options available to consumers looking to purchase a TV pertained more to the type of wood and finish of the cabinet, along with the type of ornamentation along the edges.

Advancing a Piece at a Time

Eventually, TV technology had made enough strides to offer larger screens and smaller consoles, although, during the time from the mid-50s all through the late 70s, large TV consoles were popular choices for many households, these consoles (unlike their predecessors,) housed stereo equipment like a turntable and speakers for playing records, and also additional storage space, mostly where records were stored when not being played.

These consoles took a good bit of floor space and were not necessarily the prevalent choice in every home. During this time, there were beginning to be more choices available for TV shoppers, with regard to size and other features.

During the latter part of this time span, something called portable TVs was produced, but it would be some time before these smaller versions would be made truly portable from being battery-powered, as the first ones required the use of electricity.

From Monochromatic to Full Color

It would not be until the late 1960s and early 1970s that television stations and networks dispensed with black and white TV technology and began broadcasting in color transmission. And of course, today, pretty much all television is broadcast in color.

Exceptions are older TV programs and movies that were made prior to the advent of color transmissions, however many of these have now been colorized, with reasonably realistic-looking color, added by computer technology. It wasn’t until 1972 that color TV set sales surpassed the sales of black and white TVs. Black and white TVs continued to be popular in certain niches, and especially in the function of portability, as they required the use of much less power to operate.

An LED-backlit LCD display is a flat panel display that relies on LED backlighting instead of the cold cathode fluorescent backlighting that most other LCDs use. But an LED-backlit LCD TV uses the same thin-film transistor liquid crystal display technologies as cold cathode fluorescent-backlit LCD TVs.

The picture quality is mostly influenced by thin-film transistor liquid crystal display technology, and not the type of backlight used. There are some manufacturers and TV suppliers who refer to this type of display as “LED TV,” and it is not to be confused with LED display technology. In the UK, however, the Advertising Standards Authority has officially stated that it has no objection to the term “LED TV” being used to apply to this type of display, with the stipulation that clarity is made regarding the distinction in advertising efforts.

Lcd Vs Led Tv Types

It is important to understand that LED (Light-emitting diode) TVs are actually a type of LCD (liquid crystal display.) Both Lcd Vs Led Tv are liquid crystal displays. Both TV types are designed with two layers of polarized glass. It is between these two layers that the liquid crystals work to both block and pass light.

LED differs from typical LCD TVs by utilizing fluorescent lights while LEDs use light-emitting diodes. So, in an LCD TV, the fluorescent lights are always located behind the screen. There are options for placement of the LED TV’s light-emitting diodes. To date, LED TVs have tended to be thinner, although this appears to be changing. LED TVs tend to produce more clarity and truer black, LCD TVs tend to present problems with anti-glare and angle-viewing issues, due to how thin their screens are. The backlit LED TV more dependably offers viewers a better angle than the standard LCD TV.

There are three types of LED placement options, in contrast to LCD TV’s standard placement of fluorescent lighting.

Edge-Lit LEDs feature the LEDs being located around the edge, or rim of the screen. This technology operates by use of a special panel that diffuses the light in order to spread it evenly behind the screen. This is currently the most commonly used type of LED technology.

LED backlighting (full array,) is designed to provide universal lighting that is located and provides illumination from behind the screen, without individually controlled brightness capabilities. Among the benefits associated with this type of technology (over cold cathode fluorescent-backlit LCD TVs) are less energy consumption, improved brightness, and contrast, a greater range of color, more accuracy with regard to image rendering and quicker responses to scenic changes. They also run cooler and last longer.

Dynamic “local dimming” backlight offers LEDs which are controlled in clusters or individually, depending on the specific design. This method allows for the level of intensity to be controlled as it applies to color and light production.
