Cell phone screen resolution specifications

From: http://bbs.dospy.com/thread-6036281-1-1.html

 

Our commonly used mobile phone screen uses the same LCD screen as the notebook, the resolution of the LCD screen is fixed, each point is a pixel. In addition, the cell phone resolution does not refer to the screen size, and it can be said that it has nothing to do with the screen size.
For example, a 2.1 inch LCD screen can display an image of 240x320 resolution, which is called a "qvga 2.1 inch LCD screen". A 3.8 inch LCD screen can display an image of 240x320, it is called "qvga 3.8 inch LCD screen ".

The current mobile phone screen resolution specifications are roughly divided into qvga, hvga, VGA, WVGA four types, so many application software also
The corresponding versions of various resolutions have been released one after another. For example, the popular Baidu mobile phone input method some time ago, WVGA and VGA versions have also been released. Someone once tried to install the wrong version, which eventually caused the entire
Mobile phone screens are full of software disks ......

The following describes the four resolutions in sequence.
Qvga
(Quarter VGA): The resolution is 240x320 pixels, which is the most common resolution level for smartphones. 240 ×
320 pixels means that there are 240 pixel points in each row on the phone screen horizontally, and 320 pixel points in each column vertically. The multiplication is 320 × 240 =
76800 pixels. Most early smartphones used this display-level screen.
Hvga
(Half-size VGA), with a resolution of 480x320 pixels and a Aspect Ratio. The iPhone and BlackBerry's bold 9000, which have been selling well all the time, and Google G1, the world's first Android mobile phone, all use this display-level screen.
VGA
(Video graphics array) is a computer display standard proposed by IBM early in the morning, but it has been applied to the display of mobile products. The resolution is 640x480 pixels, and the aspect ratio is. The former HTC King Diamond uses VGA resolution.
WVGA
(Wide VGA) is a VGA wide screen mode with a resolution of 800x480 pixels and 854x480 pixels. later developed by HTC, Diamond 2 and touch HD were the masterpiece of WVGA.

For screen display alone, there is no relationship between resolution and screen size. If the screen size is certain, the higher the Resolution, the clearer the screen display. In the same way, the smaller the screen, the clearer the image.

After learning about the resolution specifications of the mobile phone screen, I hope that my friends can download the desired software with good performance. Although there are not many such software at present, with the development of science and technology and the progress of the times, mobile phones are also developing towards high-resolution big screen, and software classified based on screen specifications will certainly increase
