Differences between lcd and oled
Differences between LCD and oled:
1. Display principle: LCD generates electric field effect by twisting nematic molecules of liquid crystal, and oled is composed of light-emitting material layer;
2. Thickness: the LCD screen is hard and thick, and the oled is light and thin;
3. Price: LCD is cheaper than oled;
4. The service life of LCD is longer than that of oled;
5. The color performance of oled is better than that of lcd.
Most people who pay attention to various electronic products have a certain understanding of screen displays. LCD and oled screens are more common nowadays and are widely used on various mobile phones, computers and TV screens. Although most people have heard of them, they do not have a deep understanding of these two screens, which makes people very confused when buying. They do not know which one to choose. Let's take a look at them together with the editor!
1. Display principle
The display principle of LCD is mainly to produce electric field effect through the twisted nematic molecules of liquid crystal, so as to control the light source to transmit the light and shade generated in the process of power switch, so as to display the image, while the color display mainly depends on the color filter.
The display principle of the oled is mainly composed of the light-emitting material layer. When the oled is powered on, the light-emitting material layer placed between the two electrodes conducts carrier movement, releasing energy in the form of pulses. The last electrode is transparent, and light can be seen.
