I don't know when it started, LCD TVs gradually unified the TV circle. In the past, the scenes of various TVs in the store were not seen. However, if you think that choosing a TV now will not be so entangled, then it is a big mistake.
Nowadays, the various concepts of TV sets are not less than before. What are the 4 colors and 4K, quantum dots, and various emerging concepts emerge one after another. The most troublesome thing is the concept of various "X" LEDs for TV. Not only is it similar in appearance, but the description of the business is also mysterious and mysterious, so that ordinary consumers can't figure it out. Today, Xiaobian took everyone to go to the false, and talked about the differences between the various "X" LEDs in detail.

The famous name of LED TV believes that all consumers who want to buy TV should be familiar with it. Most TVs on the market now belong to LED TV. LED full name Light-EmitTIng Diode, English looks very tall, in fact, translated is a light-emitting diode.
Some friends may have to ask, LED TV is not a LCD TV, how to become a light-emitting diode?
I don't know if you still remember the "LCD" TV in previous years. In fact, LCD stands for Liquid Crystal Display. LED TV refers to the use of LCD panels as display media and LEDs. Backlit module TV. The current LED TV is actually an LCD TV. In the past, the "LCD" TV should be called CCFL TV (Cold Cathode Fluorescent Lamp). As for the LCD TV, it can only be said that it is manufacturers and merchants. A misinformation.
ULED
ULED is a display technology on Hisense TV. Strictly speaking, ULED is not a technology, but the effect of the integration of various display technologies on Hisense LED TV. In addition to the optimization of general brightness, color and other parameters of the screen, one of the more representative technologies of ULED is partition control.
ULED has become the symbol of Hisense's high-end TV
Since the liquid crystal panel will only display color and will not emit light, the LCD TV is illuminated by the backrest light module. The ordinary LCD TV can only open and close a full-screen backlight at the same time, which causes the LCD TV to be incomplete when it is displayed in the dark. The partition control light divides the backlight into N partitions, and controls the backlight by intelligently recognizing the image. The bright place is turned on, and the black place is turned off to achieve better image quality.
Dynamic backlights can identify image content to control backlighting
It should be noted that the partition control is not a unique technology of ULED. ULED TVs must have zoned light control capabilities, but TVs with zoned light control are not necessarily ULED TVs.

QLED
I don't know if you are familiar with the concept of quantum dots. Yes, QLED is an LED TV equipped with Quantum Dot.
Quantum dots are an emerging luminescent material. After combining it with LEDs, QLED TVs have amazing color performance. QLED TV's color gamut can even exceed 100% NTSC color gamut, not only the traditional LED TV 72% NTSC and professional wide color gamut LED display 92% NTSC color gamut coverage is far away, even with OLED higher capital.
Quantum dot luminescent material
Although the quantum dot LED TV performance is very satisfactory, like ULED, QLED is also a concept used by manufacturers to promote, not all quantum dot LED TVs are called QLED.
GLED
GLED's full name Geek's LED is a concept of Skyworth's flagship. As the name implies, it represents an LED TV created for geeks and with a geek spirit. But in a nutshell, GLED is still a conceptual definition, rather than a feature of technology and technology to interpret GLED's geek spirit.

OLED
The last OLED is called Organic Light-EmitTIng Diode. Although the name looks similar, it is quite different from the previous "X" LEDs, and even the LED TV itself.
OLED has self-illuminating properties
Whether it is ULED, QLED, GLED or various "X" LEDs, the essence belongs to LED TV, and the essence of LED TV is actually LCD TV. However, although OLED is also a kind of LED (material itself), OLED TV does not belong to LED TV. The reason is that the so-called LED TV actually refers to the backlight of the TV, but the OLED TV has no backlight. OLED is a medium that not only develops color but also self-illuminates.
OLED TV, NB, not only the structure is simplified, the TV can be made thinner, even made into a variety of curved shapes, and there is no problem caused by uneven LCD backlight, color performance is also very good, there is no The "original sin" of liquid crystals such as tailings... There are so many advantages, it is no wonder that the industry is called the next generation display technology.
OLED TVs are simpler than LCD TVs, meaning the body can be thinner
However, OLED TVs are not all that good. At least for the current OLED technology, the lifetime is still better than that of various LCD TVs, and the problem of burning screens that plagued plasma TVs still existed on OLED TVs. Most importantly, the price of OLED TVs is still much higher than that of LED TVs. In terms of image quality such as color and contrast, it is also being violently affected by quantum dot TVs and LCD TVs and HDR TVs with zone control. Blocking, whoever is dead is not yet known.
