Actually, there are only two types of common TV screens on the market, one is a liquid crystal screen (LCD) and the other is an OLED screen(see LCD vs. QLED)Next, I will tell you what is LED/ULED/QLED/Mini LED/OLED/QD-OLED/Micro LED. I hope you won't be confused by the advertisement.


LED essentially refer to LCD TVs. LED means that the backlight of LCD TV is LED lamp beads. All LCD TVs currently on the market are LED backlights.



The essence of ULED is also LCD TV. This is Hisense's marketing vocabulary, which means that this model has a checkerboard-type light control partition technology and belongs to Hisense's mid-to-high-end products. However, the chessboard-type light control partition technology has been applied to a variety of brand products, and is currently relatively popular, not unique to Hisense.



The essence of QLED is LCD TV, which means using quantum dot wide color gamut technology. Wide color gamut technology is widely used in current TV sets. It can increase the color richness and make the picture color more vivid. There are two types of LCD TV wide color gamut technologies, one is quantum dot wide color gamut, and the other is phosphor wide color gamut. Generally speaking, the wide color gamut of quantum dots is better than that of phosphors, but the cost is higher and the colors are more vivid.


Mini LED​

Mini LED is also an LCD TV in essence, which means that the backlight has been upgraded. The backlights of Mini LED TVs are smaller and denser than regular LCD TVs. It has two uses. One is to improve the uniformity of the backlight of the picture and reduce the problem of dark corners. The second is to do more checkerboard-style light control partitions to finely control the brightness of different areas of the TV.



OLED is a new screen technology that is different from LCD screens. It is characterized by self-illumination of pixels, and each pixel can independently control the brightness and darkness. Therefore, OLED's picture contrast is extremely high, the three-dimensional sense is strong, the picture is transparent, and the colors are bright and natural. Its display effect is better than LCD TV, and the price is much more expensive.

OLED screens are divided into two types according to the screen refresh rate, one is 60HZ, 900 nits peak brightness. The other is 120Hz, 1000 nits peak brightness.


QD-OLED is the combination of quantum dot technology and OLED technology. The quantum dot material is added to the OLED screen through the quantum dot technology, so that the OLED screen has a wider color gamut and brighter colors, and the theoretical effect is better than that of OLED products. In addition to adding quantum dot materials, white light OLEDs also become blue OLEDs, which are used to excite quantum dot materials. QD-OLED is still an OLED in essence, so OLED will burn the screen, and so will QD-OLED.

Micro LED​

Micro LED refers to "Micro Light-Emitting Diode", which is smaller in size than Mini LED. Micro LED also does not require backlight modules and optical color filters. It uses inorganic materials to form the light-emitting layer, so it is not prone to the common screen burn-in problem on OLED, and the screen transmittance is better than LCD and OLED, and it can also save power.

Micro LED is to weld micro light-emitting diodes to a TFT substrate. The volume of each Micro LED is less than 30 nanometers, which is equivalent to 2.07 million pixels in a 1080p screen, and 8.29 million pixels in a 4K screen.
