Backlight partitioning, OLED and quantum dots. What are the differences and advantages of the three types of TVs?

There are more and more display technologies in TVs. Although it is comfortable to watch, it can also make people feel dazzled. Especially the differences and advantages between different display technologies make consumers feel a little "at a loss" when choosing. Which technology is more suitable for you?

Ordinary LCD TVs generally use LED backlights. Although the cost of smart TVs has dropped and the penetration rate has accelerated, in the era of consumption upgrades, it has become increasingly difficult to satisfy the discerning public.corning ces 2024 The main disadvantages of LED backlight are that the backlight control is not uniform enough, the color and color temperature are difficult to control, and the picture expression is relatively poor.

In addition to LED TVs, there are three more effective display technologies commonly seen on TVs: OLED, backlight zoned TVs, and quantum dots.

1.OLED TV

OLED panels have become popular in mobile phones, but in TV products they are still limited to the high-end field. OLED panels are relatively thinner and lighter, and because of the principle of self-illumination of pixels,oled panel manufacturers the black display is purer and the color performance is more vivid. The response time is faster and there will be relatively fewer smear problems.

2. Backlit zoned TV

The reason why we can see wonderful pictures on traditional LCD TVs is mainly because the backlight is projected onto the panel, which brightens the liquid crystal molecules and forms the picture. However, most backlight systems only have one control system, which is either turned on or off, resulting in The picture has low contrast, colors aren't vibrant enough, and blacks are never pure enough. The backlight partition divides the backlight into multiple independent units. According to the difference between light and dark in the picture in the TV signal, the corresponding backlight area is turned on/off to enhance contrast and color.

3. Quantum dot TV

Quantum dot TV actually uses a blue backlight to illuminate different quantum dots to form RGB three primary colors, and then image through the filter film. Because the monochromatic light display is very pure, it is also known as one of the most perfect light source materials. Quantum dot TV has high color purity and strong restoration ability, and is one of the iconic technologies of high-end TV.

The display technology used by high-end TVs is generally better, and the viewing effect is not "all TVs look the same" as some users think. At least they are better in color than common LED TVs, and can also meet the growing viewing needs of users. and quality.
