OLED, QNED and the “underground race” of technology trends
The TV market always has endless technology wars: QNED, QLED, Neo QLED, ULED, OLED, microLED, QNED, etc. However, in essence, these technologies are basically divided into two main groups: one is the traditional LED technologies, the other is OLED with many outstanding improvements.
OLED and the upper hand in technology
OLED technology stands for organic light-emitting diode. When an electric current flows through the screen, an electroluminescent layer of semiconductor material allows the screen to glow.
Displays with OLED technology will include pixels that can self-illuminate and turn on/off independently. That means when the TV needs to display black, the pixels will turn off completely and the viewer will perceive perfect black. In other words, one of the advantages of OLED TVs is high contrast.
Not stopping there, OLED TVs offer higher color saturation without the need for additional technology. The panel also does not use backlight, does not need many layers of transistors inside the panel, helping manufacturers to give users a TV as thin as they want, and at the same time reducing the amount of power compared to televisions. normally.
Undeniably, at present, LG OLED TVs are always considered the top choice in the high-end TV segment thanks to their leading position in technology and diverse choices for users.
Referring to OLED screen technology, users often think of LG OLED TV.
QNED and the battle between “rivals”
In addition to the much more advanced OLED technology, QNED and many other screen technologies are also in the sights of users when choosing a TV. QNED is essentially an LCD screen that uses LED backlighting. However, the main difference is that this backlight belongs to the mini LED type with a super small size that helps control each lighting area on the screen optimally.
LG QNED controls each lighting area on the screen thanks to the mini LED backlight.
Based on the published parameters, LG QNED is the TV series with the most LED backlights. LG’s technology uses 30,000 micro LEDs, creating 2,500 areas of local dimming and darkening, increasing the contrast ratio to 1,000,000:1. This number is higher than the 25,000 LED lights of many previous TV lines.
These mini LEDs are capable of adjusting the brightness of each small area on the screen depending on the content being displayed (also known as local dimming), so the resulting image will have extremely high contrast and brightness. frame-by-frame flexibility.
Thus, QNED and some communication LED screen technologies may be quite similar, but QNED will have many outstanding advantages thanks to the ability to control each bright and dark area on the image more optimally.
QNED technology is developed on LED panels.
Following the development of innovative technology solutions, OLED is still the first choice for all users’ needs when choosing a TV for themselves. LG is currently the leading TV manufacturer in this OLED technology with many great awards and positive feedback from users.
In particular, in the past 2021, LG OLED TV was recognized as the Technology of the Decade at the EISA grand prize. Along with the diversity from function to model of its OLED TV products, LG OLED TV is definitely the first choice for users when aiming for business class projection technology for each family.
