QLED or OLED? This is where the two technologies differ
QLED and OLED are two screen technologies that offer different advantages and disadvantages. Read here why an OLED TV should offer more intense colors and QLED hues in terms of brightness.
The terms QLED and OLED refer to two screen technologies that could not be more different. Both technologies are closely related to one plant each. For a long time, OLED screens for TVs were produced exclusively by LG, but now other manufacturers such as Sony, Loewe and Philips have also offered OLED TVs. You can find QLED displays on Samsung, Hisense, or Tcl. Read here the technical differences between QLED and OLED and what advantages and disadvantages the technologies offer.
What is the difference between QLED and OLED?
The difference between QLED and OLED is purely technical. Simple explanation: in You are The iodine lights up by itself QLEDProvides LED backlighting that lets pixels shine. QLED is an improvement on the already known LCD technology, while OLED is a standalone technology. By comparison, OLED TVs are thinner and have more contrast.
QLED TVs have several layers on top of each other. These layers include a polarizing filter, an RGB filter, a background filter, and of course, backlighting. This makes TVs thicker than OLEDs that do not need these layers. A drawback of many QLED TVs compared to OLED is that they have slightly lower contrast. The reason for this is the backlighting of QLED TVs, which also illuminates the dark and “grayed out” areas of the picture. The best models like Samsung Q95T So it introduces darkening areas, i.e. the areas in the screen that the TV lights up brighter or darker and thus controls the problem.
By the way: In Samsung you can identify the inch size by the identifier after “GQ”. 65 stands for 65 inches on the Samsung GQ-65Q950T. It is one of the best current models of the manufacturer and has a resolution of 8K. That’s still pretty bulky and you’ll be able to drive safely with a 4K TV for the next few years.
The OLED screen does not need any dimming areas. With it, each photodiode can decide for itself whether it lights up and how intense it is. This is how I get OLED TVs Better contrasts And deeper black As a QLED TV. If an iodine does not light up, it is simply black – but there is no problem with the luminosity next to it in bright white. In addition, OLED screens have a better viewing angle than QLED TVs. If you look sideways at the screen, you will see colors better with OLED. But televisions have one weak point: bright images like snow-white mountain peaks are usually very dark.
What is QLED TV?
Let’s take a closer look at QLED technology. They should be the best that LED displays have to offer, as they are considered to be particularly high-color and high-contrast LCDs.Television. It is a further development of LCD screens with so-called “quantum dots,” which are called Q. LCD stands for “liquid crystal display”: the alignment of the crystals changes through electrical pulses and the amount of light they allow to pass can vary.
Different colors are created in this way. Since the crystals do not light up on their own, a so-called backlight (background light) is required. The light is created by LEDs, which give an LCD TV the name LED TV. The further development of QLED TVs mainly affects the backlight, because with QLED TVs another layer, quantum dots, is placed on top of the already existing LED filter. They ensure that the TV can display brighter and more colorful images.
- brightness: Thanks to quantum dots, QLED’s image can be much brighter than that of LED displays.
- interview: This also increases contrast, because diodes do not lose any of their color even with increased brightness.
- Energy consumption: Since the backlight is permanently lit, the power consumption of QLED displays can be higher than that of OLED displays.
QLED TVs: Samsung Q60R
Now there are many manufacturers of QLED TVs, but Samsung is especially known and popular. The manufacturer announces that Samsung QLED devices can upscale the picture to stunning 8K with great computing power and artificial intelligence. However, buying 8K TVs is expensive. If you are looking for a good QLED TV, you should get it Samsung Q60R Watching, watching. The TV has QLED technology and should also impress gamers with a very short latency. The Ambient Mode of the TV is supposed to adapt nicely to the surrounding environment. The Quantum Processor 4K is said to be constantly improving picture and sound with the help of artificial intelligence. In addition, the Smart TV can be controlled by voice commands, it is compatible with Alexa and Google Assistant.
What is OLED?
The most important difference between a QLED TV and an OLED TV is that OLED operates without a backlight, because it is the pixels themselves that light up. They consist of millions of tiny light-emitting diodes made of organic matter – this is how the letter “O” in the name itself explains, it stands for the English word “organic”. The organic LED is a thin film luminous component made of organic semiconducting materials. This technology is used in television screens because OLEDs can be cheaply manufactured using thin-film technology. Unlike QLED screens, blacks have to be particularly intense because they are not lightened by the backlight. Colors should also appear more intense against the deep black background.
- interview: OLED screens must offer a high contrast image, which is created by rich black tones. This is due to self-illuminating OLEDs and missing backlights.
- reaction time: OLED TVs are said to have a faster response time than QLED TVs. This means that the diodes take less time to turn on or off. Therefore, a fast response time ensures that the image appears more clearly.
- Viewing Angle: The image should be easy to see from almost every corner of the room, as the light is emitted directly by the diodes, rather than being blocked by the backlight as with QLED or LED.
- Energy consumption: Since no backlight is used, which must be permanently lit, the power consumption of OLED TVs is lower than that of QLED screens.
OLED TV: LG OLED55CX9LA
LG has several OLED TVs that differ in terms of features and price. Model OLED55CX9LA Equipped with powerful α9 Gen3 processor, which is supposed to automatically optimize picture, sound and brightness. In addition, the device has Dolby Vision and Dolby Atmos as well as HDR technology, so that the contrast and colors can be adjusted dynamically. 4K resolution should allow a sharp picture and the TV is equipped with Google Assistant and Alexa. Interesting for gamers: LG OLED TV has a response time of milliseconds. Both AMD Freesync and Nvidia’s G-Snyc are on board the TV. Both technologies reduce distorted images when playing.
