There are many introductions on the Internet about how OLED and LCD work. As for the rest, OLED screens have many disadvantages, but due to the working principle of OLED screens, their lifespan is very short compared to screens. The working method of OLED screens is that countless pixels emit light and eventually image, therefore, after long-term use, OLED screens may appear afterimages, strobes and other phenomena, that is, screen damage. In addition, OLED screens are more eye-catching, and the strobe range with less impact on human health should be higher than 1250Hz. However, the strobe frequency of most current OLED screens is around 240Hz, and the gap is very obvious, so some people will feel eye pain when viewing OLED screens. There is a lot of information online about the difference between OLED screens and LCD screens. But this time, this article details the main reasons why mobile phone manufacturers choose screens from the development of mobile phones in recent years.
1. Excellent display effect
The OLED screen is really great to display. Because the OLED screen has self-luminous characteristics, it has a stronger color expression, whether it is color gamut coverage or contrast, it is far beyond the LCD screen.
2. Strong plasticity
Due to the presence of the liquid crystal layer and the backlight layer, the LCD screen cannot be bent significantly, and the OLED screen material itself is relatively soft and extremely malleable, and can be folded like origami. Both curved screens and folding screens rely on OLED technology.
3. Light and power saving
LCD has a backlight layer and a liquid crystal layer, the light and thickness are much worse than OLED, and the thickness of the OLED screen can be controlled within 1mm, for mobile phones, thinner screens allow you to insert more components, thereby enhancing the experience of using other components. Each pixel of an OLED screen is independent, so an OLED screen can light up certain pixels individually. With the screen off, light up a few pixels at low brightness to show time, lighting, and notifications. This feature can save power indirectly by significantly reducing the number of times the screen is turned on.
In general, OLED screens have more obvious advantages, although they have many disadvantages. It is under these advantages that mobile phone manufacturers will abandon LCD screens in favor of OLED screens.
