Most people who pay attention to various electronic products have a certain understanding of screen displays. The two types of screens, LCD and OLED display, are more common nowadays and are widely used in various mobile phones, computers, and TV screens. Although most people have heard of them, they have no in-depth understanding of these two types of screens. Below I will introduce the following aspects.
- Display principle
The principle of LCD is mainly to display the image by twisting the liquid crystal molecules to the cylinder to generate an electric field effect and to control the light and shade generated by the transmission of the light source during the power switching process, while the color display mainly relies on color filters. The display principle of OLED is mainly composed of a layer of luminescent material. When electrified, the layer of luminescent material placed between two electrodes performs carrier movement and releases energy in the form of pulses. The last electrode is transparent and can be seen. to the light.
- Thickness
At the same technical price point, the material of the LCD screen should be hard and thick, and it cannot be bent. This is why so many curved screens use OLED screens today because OLED screens are thinner and softer. The performance can be bent at a certain angle.
- Price
Compared with OLED screens, LCD screens appeared earlier and the technology is more mature, so the price is usually cheaper than OLED screens.
- Service life
Because the composition of the material is different, LCD is an inorganic material, while OLED display is an organic material, and many data show that LCD screens have a longer service life.
- The difference in color performance
The light emission and color of the LCD screen are mainly completed by the refraction of the backlight. When displaying black, white borders will appear on the edges of the LCD screen. The OLED screen expresses color by self-illumination, so this does not happen, and it has a better effect on the color display.
It can be seen that the development space of OLED displays is very high, and the market potential is huge. If you are also interested in OLED and looking for an OLED panel manufacturer, then FET will be a worthy and trusted partner. We will provide you with the best OLED solutions!
