Most of the Huawei screen of phones are IPS LCD with cheaper price and higher productivity. The new Huawei P40 Pro is out with OLED screen which is a good idea to attract customers. Especially after HMS is used, this is a great strategy to attract high-end consumers. If you are still wondering the difference of OLED and IPS LCD, this article is specially for you!
[Advantages of Huawei OLED Screen]
Due to the existence of a backlight layer and a liquid crystal layer, the thickness of LCD is much thicker than that of OLED. Thus the OLED screens are very easy to make mobile phones or displays thin. This has no effect on the display, and is a qualitative leap for mobile phones. The thin screen allows you to cram more components to enhance the experience of other parts.
Still because of the presence of the liquid crystal layer and the backlight layer, you cannot bend LCD screen significantly. OLED can be folded almost as easily as origami. In addition, Samsung itself supports curved screen with OLED technology. Please note that here refer to a large angle bend. You can find that the degree of bending is not large for IPS LCD. OLED can be folded in half like paper.
Contrast refers to the ratio of white to black. The higher the contrast, the darker the color of the screen. Because the LCD has a backlight layer, black is not pure black, so it is difficult to increase the contrast. OLED black does not emit light, so you can directly turn off the black area of pixels. At this time black is almost 0, so the theoretical contrast would be infinite. Here I will summarize the OLED color in one sentence. OLED is an oil painting, the color is pure and delicate. While LCD is a watercolor stroke, the color is hazy and light. I think ordinary people can tell the difference between high-end OLED and LCD at a glance.
When the LCD is on, the entire backlight layer is on at the same time. So the LCD is either fully on or fully off, and each pixel of the OLED is independent, so the OLED can light up some pixels individually. This feature allow a special and convenient function— aways on display. After the screen is off, OLED will light a few pixels with low brightness to display time, light, and notification. Samsung mobile phones can be on without turning off the screen. Now let’s know what application is the message. Double-click the message icon to light up the screen. This function can greatly reduce the number of times the screen which lits, indirectly saving power. Once you get used to it, you will fall in love with this feature.
OLED works independently because of the pixels, the light is bright, the dark is dark, and the light is off. No matter what color the LCD displays, the backlight is fully on, so the LCD will consume more power. Mix2s and Black Shark are all LCD screens, and you can see a significant battery loss in long-term video playback.
Screen response time:
We know that the color of the screen comes from pixels lit, and it takes time for pixels to change from color 1 to color 2. This is gray scale response time. If the gray scale response time is too Long, when the screen slides quickly, the pixels are too late to change from color 1 to color 2 and cause residues on the screen, and smear will appear visually. The smear will greatly affect the visual perception. The OLED screen will display white text on a pure black background In addition to smearing, there is almost no smearing feeling in daily use. Even if it is Apple’s top LCD, the smearing still occurs, and the smearing of the LCD will also be affected by the temperature, the lower the temperature, the more smearing serious.
In short, Huawei OLED screen will be a great advantages and one of the selling points to attract customers.
