TV types explained: QLED, OLED, LCD, & HD

Buying a television these days may be a problematic processor. It can be difficult for an individual because there are so many options, and it can be challenging to understand the differences between the televisions before buying. Here, we’ll go over each type of television now on the market, explain the technology behind each brand, and discuss the benefits and disadvantages along with all the details of each variant of television.

It’s helpful to understand the initial technological mechanisms of televisions to know how our current choices have developed in terms of today’s brand choices before purchasing any brand of televisions.

One of the most critical factors impacting TV selection is technological advancements, which continue to evolve the more advanced the technology, the better the experience you get and the benefits you will experience. Let us now explore all the differences between the types of televisions available today in terms of the technological resolution are as follow:

Quantum Light-Emitting Diode (QLED)


QLED TVs, or Quantum Light Emitting Diode TVs, are among the most popular types of televisions on the market today. Although Sony first introduced this technology in 2013, other companies, like Samsung, quickly followed the trend. Instead of LED lights, quantum dots, small nanoparticles are used in QLED TVs. The dots become charged when an electrostatic force passes through them, improving color and brightness. QLEDs offer higher contrast ratios and longer life spans than LCDs and OLEDs. However, because of the usage of QLED technology, the screens are relatively huge.

Organic Light-Emitting Diode (OLED)


Organic Light Emitting Diode (OLED) televisions, first launched on the market in 2012, are a cheaper alternative to LCD televisions. The use of organic light-emitting diodes instead of LED lights defines an OLED from an LCD. When an electric current flows through these compounds, the light, resulting in excellent picture quality and color display. Moreover, because the technology does not require substrates, the TVs have become much thinner and sleeker than LCD. They also have superior extreme blackness than LED TVs and are less expensive. OLED TVs also generate less heat and use around 40% less energy than LED or LCD TVs.

Liquid Crystal Display (LCD)

LCD TVs use liquid crystals, which are molecules in a fluid state but have a crystal structure that is identical to all of them. Many liquid crystal molecules are properly positioned between the two electrodes and polarising filters in each pixel. The visuals on the screen are formed by applying various voltages to different pixels on the TV screen. Many customers still prefer to use this type of televisions.

Light Emitting Diodes (LED)

An LED TV is actually an LCD TV with light-emitting diodes (LEDs) instead of standard cold-cathode fluorescent lights (CCFLs) for backlighting, so it’s not really a different type of television, but we’re including it as a separate because it’s marketed as LED instead of LCD. It’s similar to LCD TVs.

HD (High Definition) (1080p)

Most people regard full high-definition 1080p as the industry standard for televisions. The image on these televisions is 1920 x 1080 pixels. The pixels on a 32-inch 1080p panel are more than double those on a 32-inch 720p screen. Viewers will experience sharp visuals when viewing a 1080p screen at most screen sizes. The image quality difference between 720p and 1080p screens is quite noticeable.

1080P TVs

n the market, 1080P TVs are commonly referred to as Full-High Definition or Full HD TVs. These televisions have a horizontal 1920-pixel structure and a vertical 1080-pixel pattern across the screen. The ‘p’ in 1080p TV stands for progressive screens, which means the picture aspect ratio is 16:9. Compared to earlier-generation TV kinds such as 720p, 1080p TVs are more low cost. They also have the capacity to take broadcasters’ 1080p or Full HD signals without converting them to a lower quality. However, with the introduction and launching of 4K and 8K technology, Full HD televisions may soon become outdated.

Flat TVs

Flat TVs are one of the most popular types of televisions, and they differ from the others in terms of screen design. These TVs have a thin, flat display that can run on any technology, including Plasma, LED, 4K, and 8K. It’s no surprise that these thin, lightweight screens have displaced heavy CRT TVs with a thickness of more than 30 inches. Flat display panels are used in most 21st-century televisions because of their low power usage, compact appearance, and simplicity. There are two types of flat TVs: static and volatile. Static ones can hold the image without using any energy, but changing them requires energy. To keep the image visible on volatile screens, power is constantly needed.

Digital Light Processing (DLP)

Texas Instruments introduced Digital Light Processing (DLP) televisions in the 1980s to address the issues with older television models. DLP TVs have a chip known as the Digital Micromirror Device (DMD), which uses millions of miniature mirrors known as Pixels. When a magnetic current is applied, these mirrors tilt towards or away from the screen, causing the images to appear. The picture quality of DLP TVs is similar to that of LCD TVs. Fast-moving visuals like sports or racing seemed far better than other TV variants due to the high-speed movement of mirrors. Due to the competition from newer technologies, DLP production was discontinued by 2012.

Plasma Panels

After many customers moved from ordinary Cathode Ray TVs, Plasma Televisions (PDPs) became extremely popular in the early 2000s. Plasma TVs were in high demand by 2007 due to their thinner screens and excellent picture quality. Plasma is an ionized gas that can react to electricity, and it gives these televisions their name. The TV screen is made up of a pattern filled with plasma that lights the pixels. Featured a faster frame rate and higher color contrast in contrast to their predecessors. However, by 2015, the technology had become outdated due to its high cost and permanent picture storage (burn-in) and the debut of LCD and OLED displays.


These are a few of the several types of televisions you’ll find in any electronics store. Now that we all know the common differences between them, make a list of the features you want and choose the style that gets to you the most.
