What are the advantages and disadvantages of curved screen and straight screen?

Today's mobile phone configuration has been greatly improved with the progress of science and technology. The most obvious change is that the original mobile phone screen is a straight screen, and now we see more curved screen mobile phones. As two screen technologies, straight screen and curved screen have different advantages and disadvantages, which are described in detail below.

First, the advantages of curved screen: good elasticity, strong sense of advance and strong visual effect.

Because the curved screen uses non-rigid glass as the base material, it has better elasticity and can further reduce the wear rate of the screen. The design of the curved screen is arc-shaped, which is more conducive to hand holding and can be operated across screens when used. The full screen looks very advanced, especially the big screen, which is very comfortable to use in games or movies.

Second, the disadvantages of curved screen: expensive, easy to touch by mistake, difficult to film.

The disadvantage of curved screen is also very shallow and obvious, because this technology is not mature enough, so its cost is very high and the price is relatively expensive. Another is that the mobile phone screen itself is fragile, and it is very expensive to change the screen after it is broken, especially the curved screen. Once it breaks down, the whole screen has to be changed, and the price is higher.

The curved screen itself has no border, so it is easy to touch it by mistake.

Both sides of it are arc-shaped, and the ordinary toughened film can't be attached at all, so it is very difficult to attach the film, and the edge of the film will be prone to fuzzing after a period of time.

Third, the advantages and disadvantages of flat screen: cheap, visual effects have an impact.

The biggest advantage of flat screen is that it is relatively cheap. Most low-end domestic mobile phones use flat screens. The technology of this screen is relatively perfect. For mobile phone manufacturers, the production cost is relatively low and the installation is convenient.

Another is phablet's high cost performance. If it is only used for making phone calls or watching videos every day, it is not only cheap, but also has a long service life and is relatively cost-effective.

However, the disadvantage of this kind of screen is that the visual effect is not as good as that of curved screen, and the long-term use of flat screen is more irritating to the eyes. Flat phones are not very extensible. Once you touch the ground by mistake, it is easy to break the screen, and it is time-consuming and laborious to replace the screen.

Classification of mobile phone screens:

According to the material of the screen, the mainstream screens of smart phones can be divided into two categories. One is LCD (abbreviation of liquid crystal display), that is, liquid crystal display, such as TFT, s LCD screen, etc. The other is organic light-emitting diode (short for organic light-emitting diode), that is, organic light-emitting diode, such as AMOLED series screen.

The most fundamental difference between LCD and organic light-emitting diode is that organic light-emitting diode is self-luminous, while LCD needs backlight illumination to display.

According to the driving mode of screen display technology, it can be divided into passive matrix and active matrix. The difference between passive matrix and active matrix lies in the driving mode of current.

When an external current passes, the arrangement of liquid crystals will change. After the current stops, if the liquid crystal arrangement does not return to its original position (memory), it is called active matrix. Once the current disappears, it will return to its original position and must be recharged before it can be arranged. This is the so-called passive matrix.
