Let us first talk about the difference between these two display technologies. LCD is a traditional liquid crystal, which is composed of five parts: backlight, polarizer, liquid crystal molecule, color filter and polarizer. The backlight provides a light source, and the polarizer is used to convert the format to the liquid crystal processing adjustment. After the color filter is colored, the final image is displayed by the polarizer, which is the working principle of the LCD screen.
Let's look at OLED. Its full name is organic light-emitting diode, which is an organic self-luminous material. Unlike LCDs, OLEDs are very thin and light because backlight modules are no longer needed. In addition, thanks to the characteristics of self-luminous, it also has many advantages such as high luminous efficiency and low energy consumption. In many fields, OLED is regarded as a new generation of display technology.
From a technical point of view, it is obvious that OLED has an advantage. First , the thickness of the OLED screen is only 1/3 of that of the LCD, which provides conditions for the mobile phone to become thinner and lighter.
In addition, OLED screens can display more pure black, and theoretically can present infinitely high contrast, which is difficult for LCDs to achieve. But the biggest advantage of LCD is its low cost, so in order to attract more consumers, Apple did not give up the LCD screen this year.
