There are many kinds of mobile phone screens. If we distinguish from the types of panels, there are two main types: organic light-emitting diode screens and LCD screens. The main representatives are iPhone 1 1 Pro and iPhone? 1 1。 Organic light-emitting diode (OLED) screen adopts pixel self-luminous technology, and each pixel on the screen can emit light independently without backlight. Therefore, the organic light-emitting diode screen has the characteristics of thin, bright color and high contrast. More advanced OLED screens can also be folded, so now high-end mobile phones basically use OLED screens.

LCD screen is a kind of traditional LCD screen, which uses backlight to illuminate the LCD screen to display content. The advantages of LCD screen are no stroboscopic, less pressure on eyes when used for a long time, and more transparent colors. However, the development of LCD technology is not long, so most low-end models now use LCD screens. According to the screen style, there are full screen, Liu Haiping screen, water drop screen, hole digging screen and waterfall screen. Full screen: As the name implies, the front is full of screens. This kind of screen is rare, because there should be an area on the front of the phone to place the front camera. However, some mobile phones adopt the structure of lifting camera, and the front camera is housed inside the fuselage, thus achieving a real full-screen effect. The representative models are OPPO Find X, Redmi K30 Pro, glory X 10, etc.

Dropping screen: The front camera is placed in the middle of the top of the screen and looks like a drop of water. Representative models are Xiaomi 9 and Huawei P30 Pro.

Liu Haiping: In addition to the front camera, some high-end mobile phones also have 3D structured light sensors for face recognition, so it is necessary to leave more space at the top of the screen to look like human bangs. The representative models are iphone x/xs/1111pro, Huawei Mate 20 Pro and so on.

Waterfall screen: Generally speaking, the curvature of the left and right edges of the screen is high, the volume key of the entity is cancelled, and the border is covered by the screen. Looks like it? Representative models like waterfalls include Huawei Mate 30 Pro and vivo NEX3.

Digging screen: This kind of screen is more popular this year, that is, putting the front camera in the upper left corner or the middle inside of the screen looks like digging a hole in the screen. Representative models include Samsung S20 series, one plus 8 Pro and so on. In addition, there are double digging screens, and the representative models are Glory V30 and Huawei P40.

Generally speaking, there are various screen forms of smart phones, but the main purpose is to increase the proportion of screens, so that more content can be displayed on the front of the phone and the face value is higher. With the emergence of off-screen camera technology, full-screen mobile phones will be further developed in the future.
