The QLED TVs and OLED TVs are the two major display technologies currently in the market. The major difference between them is that OLED uses organic light-emitting diodes (OLEDs) for creating color, whereas QLED uses quantum dots. Due to this difference, QLED TVs enjoy better picture quality with wider viewing angles than OLEDs do. But how do you know which one is perfect for you? Read on to find out!
QLED TVs are a type of LCD (liquid crystal display). It is a technology quite similar to OLED. Both are used to create digital displays and emit light in response to an electric current. The Q in QLED means Quantum dots (QD) which are cutting-edge color technology in QLED TVs. Quantum dots are exceedingly small inorganic nanocrystals. When a quantum dot is struck by light, it glows with the most finely tuned color. The quantum dot backlight reproduces the most true-to-life color. In other words, a QLED TV is actually an LED-backlit LCD TV with quantum dots added on top of it. Having said that, quantum dots are a neat feature, and they can significantly enhance image quality.
OLED refers to Organic Light-Emitting Diode. OLED TVs are fundamentally different from QLED TVs, which have LCD screens as their display technology.
The first functional OLED device was created in 1987 by Eastman Kodak chemists Ching Wan Tang and Steven Van Slyke. To achieve recombination and light emission in the middle of the organic layer, this device used a two-layer construction with separate hole carrying and electron transporting layers. This led to a decrease in operating voltage and an increase in efficiency.
OLED TV technology comes in various forms. With OLED TVs, backlights are completely unnecessary. An OLED enables every subpixel to generate its own light. This allows accurate pixel-level control of contrast and black levels, which is not achievable with QLEDs.
- QLED display is capable of achieving a higher brightness than you can get from an OLED screen. This capacity for greater brightness, when combined with HDR and WCG (Wide Color Gamut) technology, enables a QLED TV to have a better contrast ratio (the difference between the brightest and darkest part in an image), produce a varied, vivid, and dynamic looking color spectrum, as well as a more lifelike looking picture quality.
- The light that each quantum dot emits is so tied to its size, that the colors can be tweaked to produce the colors required. As a result, they will be quite accurate and "pure" for the colors the dots emit.
Additionally, when high brightness and accurate color performance are combined, QLED TVs are perfectly able to produce more color volume than other comparable displays. As a result, colors will stay vibrant and expressive as a TV's peak brightness increases. Traditional OLED TVs aren't as good at this as QLED could be.
- For the final advantage, QLED TVs are completely free from image retention and more severe burn-in that can damage the screen like OLED TVs. Without any worry, you are free to watch news stations around-the-clock and play video games all day. Although, as we said, if you use an OLED routinely, image preservation shouldn't be a problem.
The TCL C735 features a 4K HDR display with Dolby Vision support, a 120 Hz refresh rate, and a dynamic contrast ratio of 100 000:1. The TV also has local dimming, allowing you to see dark areas of the screen in greater detail. The edge-less design of the C735 enables full-screen and wider viewable viewing, which feels natural among all the activities.
Besides, it has a set of internal speakers with high sound quality. Extra sound equipment is not needed. The multi-zone remote control allows you to control different devices from one remote.
For those seeking a high-quality image at a reasonable price, this QLED TV is immaculate! If you're looking for a new home entertainment system, the TCL C735 is a great choice. A silky-smooth gaming experience with less latency, minimal tearing, and the instant control command is available by Game Master mode.
The TCL C635 delivers vibrant colors while maintaining clear images even at wider viewing angles (upwards of 178 degrees).  
It also features a powerful processor ensuring even the most high-definition and globally superior games function without any hiccup. With TCL C635, you can simply manage all your work by casting your laptop onto your large-screen TV with up to 4K quality.
The TCL C735 also comes with a built-in Roku smart platform accessing thousands of streaming channels. You can watch Netflix or Hulu without need to buy an additional streaming box or stick. The TV has built-in Wi-Fi and Ethernet ports for direct connection to your router, aiming at faster browsing speeds or Ethernet cable use if Wi-Fi isn't available in your area.
Among your accessible subscriptions and contents, you could find new movies and television shows. Recommendations based on what you've enjoyed and what interests you help discover your next favorite.
It’s clear that QLED TVs and OLED TVs have come a long way in the past few years. They both have advantages and disadvantages, even though they are still quite different technology. Most people would be happy with either of these technologies if they were buying a new TV today based on price alone. However, when it comes to choosing between them for your next investment, there are several factors to consider before making your decision: size, resolution, or brightness level among others. TCL provides its customers with a range of options. TCL has you covered for whatever you need.
