Although OLED screens and LCD screens are both one screen, OLED screens and LCD screens are two completely different screens. Nowadays, the mainstream screen types, whether for industrial use or mobile phone and computer screens, mainly include LCD screens and OLED screens.
First, the working principles of LCD screens and OLED screens are different.
LCD screens require backlight layers, vertical polarizers, positive circuits, liquid crystal layers, negative circuits, horizontal polarizers, and color filters. The bottom backlight layer emits light.
The OLED screen only has positive and negative circuits and light-emitting diodes, and it can emit light by itself without the need for a backlight.
Because of its light-emitting mechanism, LCD has a low degree of reduction, far less than OLED. One is that the backlight emits light through the film, and the other is self-illuminating, and light leakage is common in LCDs, especially in dark environments, OLED has an advantage in terms of screen display quality.
Second, the power consumption of LCD screens is different compared to OLED screens.
The LCD screen has a backlight layer, so the entire screen needs to emit light, while the OLED screen does not have a backlight layer, so the OLED screen can emit light individually for each pixel, which has a very good feature: power saving, this is what we call it. Low power consumption screen reminder.
Third, the contrast between LCD screen and OLED screen is different.
We all know that the higher the contrast, the more vivid the colors. OLED screens benefit from the self-illumination of light-emitting diodes, so the contrast displayed will be extremely high. The polarizer cannot be completely closed, causing some white light to leak out. This causes light leakage in the impure black color of the display.
The PWM (Pulse Width Modulation) frequency range of the OLED screen is 50 to 500Hz, while the frequency of the LCD is higher than 1000Hz. The highest sensitivity of the human eye to flicker is only 250Hz, so the OLED screen is easier to operate than the LCD. Causes eye fatigue.
Because LCD uses a backlight to emit light, the light source is stable, so there is no need to worry about screen flickering. However, the color change of OLED screen means that the light flashes frequently, and long-term viewing of LED lights will cause visual fatigue to users.
Fourth, the service life of LCD screen is different compared with OLED screen.
OLED displays by changing the voltage of light-emitting diodes. One disadvantage of light-emitting diodes is that they have a short lifespan, so when it displays a certain color for a long time, its lifespan will be different from that of diodes of other colors, resulting in color differences. We often call it screen burn.
Because the LCD screen emits light from the backlight layer, even if it ages, the obvious difference will not be visible to the naked eye. Therefore, OLED screen mobile phones are prone to screen burn-in, so in terms of screen life, LCD has an advantage.
Fifth, the thickness of LCD screen is different compared to OLED screen.
The LCD screen is made of seven materials: backlight layer, vertical polarizer, positive circuit, liquid crystal layer, negative circuit, horizontal polarizer, and color filter. The OLED screen has a simpler structure, is thinner, and has better curvature. , so compared to LCD screens, OLED screens have an advantage.
How about LCD screen compared to OLED screen? Let us briefly summarize the differences between LCD screen and OLED screen.
Advantages of LCD screen: no screen burn-in problem, low cost, stable color
LCD screen disadvantages: impure color, high power consumption, light leakage, thicker
Advantages of OLED screen: low power consumption, high contrast, thin and light, rich colors
Disadvantages of OLED screens: high cost, flash screen burn problem, low lifespan
The advantages of OLED screens are very obvious, and the disadvantages are also very obvious. Both LCD and OLED have advantages and disadvantages. The key is who uses them? Reasonable application of different screens will provide better results for different products.
