Maybe we don't pay much attention to the type of screen when we buy a mobile phone, and only pay attention to it when we buy a TV or a display screen, so many people don't know the advantages of these types. So, what is the difference between
lcd and oled? The following will introduce to you.
The difference between lcd and oled
1. What is
LCD and OLED?
LCD is a display method, its working principle is to control light-emitting diodes in semiconductors, in general, it is composed of multiple red lights;
The working principle of the OLED screen is that under the drive of a stable voltage, holes and electrons are injected from the anode and cathode to the hole transport layer and the electron transport layer, and then move to the light-emitting layer respectively. After the two meet, they will form excitons. , the excitons will activate the light-emitting molecules in the light-emitting layer, thus emitting visible light;
2.The difference between the two
First, in the color gamut, the OLED screen can display an infinite number of colors, and it is not affected by the backlight. The pixels are very advantageous when displaying a completely black picture. The color gamut of the
LCD screen is currently. Between 72% and 92%, and the color gamut of the LED LCD screen is above 118%;
Second, in terms of price, the LED LCD screen of the same size is more than twice as expensive as the LCD LCD screen, and the OLED LCD screen is more expensive;
Third, in terms of technology maturity, because LCD LCD screen is a traditional display, it is much better than
OLED screen and LED LCD screen in terms of technology maturity, such as display response speed, OLED LCD screen, LED LCD screen Compared with the performance of LCD liquid crystal display, there is still a certain gap;
Fourth, in terms of display angle, OLED liquid crystal screen is much better than LED liquid crystal screen and LCD liquid crystal screen. The specific performance is that the viewing angle of the LCD screen is very small, while the LED liquid crystal screen has a sense of hierarchy and dynamic performance. The above is not satisfactory, and the depth of the LED screen is not good enough;
