Edge-lit LED TVs beam light from the sides of the screen to the back and allow for ultra-thin cases. Although some designs provide selective dimming, edge-lit backlights are not as effective as the full-array method. In addition, they have a tendency to be brighter at the edges than at the center. The full-array covers the entire back of the screen with LEDs. Although the case is thicker than edge-lit designs, the full array provides better details in shadows and more contrast. Although an LED TV is really an LCD TV with LED backlighting, the industry branded them as LED TVs to avoid monikers such as "LED backlit TV" or "LED-based LCD TV." Today, all new TVs are LED TVs. A flat panel LCD TV set that uses LEDs (light emitting diodes) as its backlight source rather than the earlier cold cathode fluorescent lamps (see MicroLED and CCFL). Smaller, more power efficient and having a greater optical range than the fluorescents, LED TVs produce deeper blacks and more saturated color. White LEDs are less costly, while red, green and blue (RGB) LEDs provide a richer color gamut. There are three "local dimming" techniques for backlights, which dynamically dim the light behind black areas of the screen images to make them darker. The direct-lit method in low-priced TVs uses a sparse array of LEDs across the back.

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different in important ways. Let’s dig into each. CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “self-emissive” displays, which means they require no backlighting at all. These kinds of TVs, made popular by LG, offer incredibly deep contrast levels and better per-pixel accuracy than any other picture tech on the market. And because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. Then there are the QLED TVs — think of them as a kind of supercharged LED TV –that were made popular by companies like Samsung, TCL, and Hisense. You might have heard of LCD TVs and monitors, you might know what LEDs are, but how they relate to new TVs isn’t especially clear. Alongside their best OLED TVs, Samsung, LG, Sony, TCL, Hisense, and every TV brand under the sun also offer a range of LED-lit, LCD TVs. That’s where we can step in to help. Whether you’re looking to buy a top QLED TV, want a super-bright LED for watching outdoors, or are just interested in understand the difference between LCD and LED, this guide is for you.

With a myriad of different options available it can be difficult to decipher what each different TV screen type on the market can do and, more importantly, what this means for the everyday use of your TV. We’ve broken down the different key terms related to TV Screens below into bite size chunks that will hopefully help you feel informed enough to make the right decision when choosing your next TV. All TVs rely on LEDs in some capacity as they provide light and contrast to what you’re viewing on screen. We hope this deep-dive into different screen types and resolutions has proved helpful in your search for the perfect TV. We are of course on hand to help if there’s anything further that we can help with. ... Video: OLED vs. Full Array LED: What's The Difference LED stands for Light Emitting Diode which, when put simply, means that it will act as a light source for the pixels on the screen that produce the image you see. There are three main types of LED screen, with QLED introduced by Samsung as an LED alternative. We go into the different options available in more detail below so that you can hopefully make the best screen decision. An Edge Lit LED screen does exactly what it says on the tin. A step-up from Edge-Lit models, a Full-Array LED screen is fully backlit meaning the LEDs are evenly distributed behind the entirety of the screen. This results in better contrast as light is focused on the area of the screen that needs it and dimmed in darker areas of the screen.
