We often hear O led LCD screen, LED LCD screen and LCD LCD screen. These are all types of LCD screens. However, many people do not know what these three are? What do they mean? Let's make a simple Describe the difference between these three screens.
OLED LCD screen, LED LCD screen and LCD LCD screen working principle
Before understanding their differences, let's first understand how they work.
LED is what we often call a light-emitting diode, which is a semiconductor fixed light-emitting device. Its working principle is to use a solid semiconductor chip as a light-emitting material, and then apply a voltage to both ends, so that the carriers in the semiconductor react in a certain way. produce light.
LCD is a display method. Its working principle is to control light-emitting diodes in semiconductors. Generally, it is composed of multiple red lights.
The working principle of the OLED LCD screen is that under the drive of a stable voltage, holes and electrons are injected from the anode and cathode into the hole transport layer and the electron transport layer, and then move to the light-emitting layer respectively. The excitons activate the light-emitting molecules in the light-emitting layer, thus emitting visible light
The difference between OLED LCD screen, LED LCD screen and LCD LCD screen
After understanding their working principles, you must have a general understanding of OLED LCD screen, LED LCD screen and LCD LCD screen. Let's focus on the differences between the three.
First, in the color gamut, the OLED liquid crystal 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 OLE LCD screen is more expensive.
Third, in terms of technological maturity, because LCD liquid crystal screen is a traditional display, it is much better than OLED liquid crystal screen and LED liquid crystal screen in terms of technical maturity, such as display response speed, OLED liquid crystal screen, LED liquid crystal screen Far less than the LCD liquid crystal display.
Fourth, in terms of the angle of the display, the OLED LCD screen is much better than the LED LCD screen and the LCD LCD screen. The specific performance is that the viewing angle of the LCD screen is very small, while the LED LCD screen has a sense of hierarchy and dynamic performance. The above is not satisfactory, and the depth of the LED LCD screen is not good enough.
