Mobile phone operation mode:

1, key type. Push-button mobile phones used to be the mainstream of the mobile phone market. Since the birth of the mobile phone, it has various types of buttons. At the earliest time, the mobile phone was the only medium to interact with users, and the importance of the keyboard was self-evident. All operations such as making phone calls and sending text messages could be completed through the keyboard.

2, touch screen type. Touch screen mobile phone is the trend of modern mobile phone market. Touch screen mobile phones can be divided into resistive screen and capacitive screen mobile phones, which refers to a kind of mobile phones that use touch screen technology to apply this technology to the screen of mobile phones. There is no clear boundary between touch-screen mobile phones and other mobile phones. The biggest feature is its large screen, which can bring visual enjoyment to users, and embodies the characteristics of large screen in words and images.

However, due to the large screen and volume, carrying a touch-screen mobile phone takes up a lot of space. At the same time, the touch-screen mobile phone can be controlled by fingers, which perfectly replaces the keyboard.

Oppo mobile phone technology innovation:

1, dual-core focusing. Dual-core focusing is a focusing technology of OPPO R9s based on Sony IMX398 sensor. "Dual-core" means that the photodiode in a pixel is divided into two, so that the separated photodiodes can receive light independently, and the phase difference formed is the "basis" for driving the motor to focus. When imaging, two independent photodiodes can be output (merged) as a pixel.

Dual-core focusing is like seeing things with both eyes, while ordinary PDAF phase focusing only uses left and right eyes to see things. This means that the light input of a single focusing pixel increases by 100%, and the focusing accuracy and speed will also be improved.

2, ultra-clear image quality. Ultra-clear image quality refers to a camera technology exclusively developed by OPPO, that is, multi-frame composite oversampling technology is used to synthesize multiple photos with CMOS effective pixel output size into a super-high pixel photo to obtain larger frames and more details.

OPPO Find 7 is the first smart phone equipped with ultra-clear image quality technology, which can output photos with a maximum of 50 million pixels. OPPO N3 has been improved on the basis of Find7, and can output photos up to 64 million pixels. Most smart phones such as OPPO's R9s and R9s Plus can be equipped with ultra-clear image quality.
