What is the difference between LCD screen and OLED screen of mobile phone screen? Which to choose? finally understood!

Regarding the mobile phone screen, we often hear Liu Haiping, full screen, waterfall screen, etc. In fact, these are just the display form of the screen. In the final analysis, the common mobile phone screens on the market are mainly LCD screens and OLED screens. For example, Apple released the new iPhone 11 series last month. The iPhone 11 uses an LCD screen, while the iPhone 11 Pro and iPhone 11 Pro Max use an LCD screen. OLED screen.

For these two types of screens, there are also two kinds of voices. Some users think that the OLED screen is better, and some users think that the LCD screen is better.

What is the definition of LCD screen and OLED screen?

LCD screens are commonly referred to as liquid crystal displays, which are relatively common and are generally found in homes. It does not have self-illumination characteristics and needs backlight support. These backlights can only emit white light. In order to project the three primary colors, a layer of color filters is needed to color.

The OLED screen is an organic self-luminous material, which itself has luminescent properties. When a current passes through, these organic materials will emit light by themselves, projecting light in three primary colors of red, green and blue. Especially when the black interface is displayed, the screen and the black panel of the phone are almost integrated. A more refined OLED screen is divided into AMOLED screen and Surper AMOLED screen.

Comparison of LCD screen and OLED screen

01 Imaging effect

Because LCD has a backlight layer, it emits light by refracting light, the color saturation is not so high, and the display effect is more natural. Correspondingly, the LCD screen is not easy to be fatigued when watching it for a long time, and it is more eye-friendly.

OLED can emit light by itself, and each pixel can project light of three primary colors of red, green and blue, so the display effect is more vivid and full. However, since the OLED screen cannot guarantee the same light-emitting effect of each sub-pixel, it is also prone to screen burn-in.

02 Screen thickness

The LCD screen is relatively thick and cannot be bent, which also determines that mobile phones with this screen have relatively large borders, such as the iPhone 11. OLED screens, on the other hand, are thinner and bendable.

As mobile phones become more and more full-screen, major mobile phone manufacturers are increasing the screen-to-body ratio of mobile phones, hoping to hide more components under the screen, such as screen fingerprints, under-screen cameras, etc. Thin, thin and bendable is just in line with the development needs of a full screen, so more and more mobile phones are now using OLED screens.

03 Price

LCD screens have been developed for a long time, the technology is very mature, and the cost is lower than that of OLED screens.

04 Service life

The LCD screen uses inorganic materials, while the OLED screen uses organic materials, which age faster. Therefore, the LCD screen is advantageous in terms of service life.

Summarize

Comparing LCD screen and OLED screen, it can be found that both have their own advantages and disadvantages, but they are not perfect. If the OLED screen is a player with unlimited potential, then the LCD screen is also a player with stable performance. Everyone can choose according to their own preferences when purchasing. It is very unscientific to judge whether a mobile phone is good or bad based on whether it is an OLED screen!
