The advantages and disadvantages of OLED and LCD, the difference between OLED and LCD part two

The LCD screen originally used CCFL backlight, but now it has been changed to LED backlight. In addition, some liquid crystal displays have not only used white backlights, but even achieved some more difficult purposes through the combination of specific color LED backlights and white light.

Although the backlight comes from the liquid crystal layer, most of the LED backlight light source comes from the edge of the screen, usually at the border, and this design can make the screen thinner and flatter.

And TV products usually do not have that high requirement for thickness, so the overall uniform backlight method is also used, and such light can be more uniform, and the backlight can also be adjusted for local areas.

LCD IPS and PLS

The advantages and disadvantages of OLED and LCD, the difference between OLED display module and LCD

The full name of IPS is In-Plane Switching (also called Super TFT), which is a variant of LCD display. IPS can provide better color accuracy and a wider viewing angle. Ordinary LCD screens usually display the best fresh fruits only right in front of the screen.

IPS can fully replicate the color effect in the range of 178 degrees, and will not be affected in any way. And this is why most touch devices now start to use IPS displays. Yes, the traditional LCD display screen will have strange effects when pressed with your fingers. I believe everyone has had a similar experience.

At the same time, IPS technology itself has more improved versions, including Super-IPS (S-IPS), Advanced Super IPS (AS-IPS) and IPS-Pro, etc. Although not all IPS panels have the best results, but In general, IPS is better than traditional LCD panels.

And PLS (Plane Line Switching) is also a technology similar to IPS, which is a patent of Samsung. Samsung said that this screen has better brightness and more efficient production costs, but it is still uncertain because the absolute leader of IPS displays on the market is LG.

LCD+quantum dot

Quantum dots are a technology that can improve the color and tone of LCD screens. Semiconductor nano-bulk quantum dots can absorb a specific spectrum, which usually depends on their size. And this attribute can be used/created better colors, such as red, green and blue, and this will bring users more saturated colors.

Quantum dot technology has recently been enthusiastically sought after by the market, and even has the strength to compete with the latest technology such as OLED. However, the current quantum dot technology only exists in high-end LCD TVs, but it is believed that it will gradually become popular over time.
