Speaking of smart phones, we have to talk about the current control mode of mobile phones. Most of today’s smart phones are touch-screen. And it is a finger touch screen. This touch screen is called a capacitive screen in professional terms. The company that first applied the capacitive screen to smart phones was apple. At that time, it was Apple generation. Later, we all know that touch-screen mobile phones have become popular rapidly. Until now, the elderly and children are using touch-screen mobile phones.

But you know what? The earliest smart phones were resistive screens, which were operated with a stylus. The use history of resistive screen is much longer than that of capacitive screen, but why did the powerful resistive screen almost withdraw from the market and the capacitive screen become popular? This starts with the advantages of capacitive screen.

The biggest advantage of the capacitive screen is that it can be operated directly with your fingers without the help of any tools. In this way, it is very convenient for us to operate. In the past, smart phones had resistive screens. We also need to prepare a stylus. In case the stylus is lost, the screen will be difficult to touch. But with the current capacitive screen, you don’t have to worry. As long as you touch with your finger, the mobile phone can be operated smoothly.

Another advantage of capacitive screen is multi touch, which means that multiple contacts of the screen can be operated at the same time. This can play well in the game, for example, in case we play a racing game. The left hand can control the direction of the car, while the right hand can control the accelerator and gear of the car. In this way, the playability of the left and right matching games is very high.

Instead of the previous resistive screen, we can only use a single touch. When playing racing games, we can only locate the gear and then control the direction. If you need to shift gears, you can only fix the steering wheel to shift gears. The game experience is very poor. When zooming in and out, we can easily zoom to the appropriate size with the capacitive screen, while the resistive screen needs to call out the zoom in button and zoom out button, which is very troublesome step by step.

The capacitive screen quickly replaced the resistive screen and occupied the market through these two advantages, but although the capacitive screen is good, it still has some disadvantages, which are difficult for office and designers to accept. One disadvantage is that the capacitive screen can not achieve fine handwriting operation. Some business users are used to handwriting notes, but the capacitive screen can not meet the needs of users.

Another disadvantage is that the capacitive screen does not perform well in fine painting. Compared with the precise touch of the resistive screen, the resistive screen still has an advantage in painting and design. When painting fine lines such as human hair, the resistance screen can show incisively and vividly, while the capacitance screen is very rough. But in the final analysis, the mass market is still the mainstream market. After all, the number of designers and business people is a minority, so it is still the world of capacitive screens.
