On the question of phone resolution, what is the phone resolution

The resolution of the mobile phone is the number of pixels displayed on the screen, which is one of the important parameters of the mobile phone.

When the screen size is the same, the higher the resolution, the more detailed the display effect. Screen resolution determines the setting of how much information is displayed on a computer screen, measured in horizontal and vertical pixels.

Resolution can be roughly classified from two directions: display resolution and image resolution. Display resolution (screen resolution) is the precision of the screen image and refers to how many pixels the display can display.

Since the dots, lines, and surfaces on the screen are made up of pixels, the more pixels a display can display, the finer the picture will be, and the more information can be displayed in the same screen area, so resolution is one of the most important performance indicators. Think of the image as a large chessboard, and the resolution is expressed as the number of intersections of all the meridian and latitude lines.

When the display resolution is noisy, the smaller the display, the clearer the image, and conversely, when the display size is fixed, the higher the display resolution, the clearer the image. Image resolution is the number of pixels per inch, and its definition is closer to the definition of resolution itself.

Common screen resolutions:

1、qvga

QVGA is the abbreviation of Quarter VGA, which means a quarter of the VGA resolution, which is the most common mobile phone screen resolution before the popularity of smart phones, vertical is 240 320 pixels, horizontal is 320 240 pixels. The vast majority of mobile phones use this resolution, such as the Nokia E66, which used to be QVGA-level.

2、hvga

HVGA stands for Half-Size VGA, which means half the resolution of VGA, which is 480 320 pixels and has an aspect ratio of 3:2. Screens of this resolution are mostly used for PDA.

Of course, both the iPhone and the first Google phone, the T-MobileG1, use this resolution, and BlackBerry also has a screen with HVGA resolution. The iPhone 3GS uses a screen with HVGA resolution.

3、wvga

The full name of WVGA must be easy for everyone to think of, that is, Wide VGA, with a resolution of 854 480 pixels and 800 480 pixels. Since many web pages are 800 pixels wide, this resolution is usually used for rock-finger PDAs or high-end smartphones to facilitate users to browse the web. Most of Sharp's mobile phones also use WVGA-level resolution screens.

What does resolution mean? Display resolution is the number of pixels displayed on the screen, resolution 160 128 means 160 horizontal pixels, 128 vertical pixels. The higher the excitation resolution, the higher the number of pixels, and the more precise the perceived image.

And in the case of the same screen size, the higher the resolution, the more refined and delicate the display effect.

For a screen with a resolution of 1024 768, that is, each horizontal line contains 1024 pixels, with a total of 768 lines, that is, the number of scanned columns is 1024 columns, and the number of rows is 768. Resolution is not only related to the display size, but also affected by factors such as CRT point spacing, bandwidth, etc. Among them, it is closely related to the refresh rate, strictly speaking, only when the refresh rate is "flicker-free refresh rate", how much resolution can the display reach, can the highest resolution of this display be.

Resolution and point spacing are conflated, but these are two very different concepts. Point distance refers to the distance between pixels and points, the more pixels, the higher its resolution, therefore, the resolution is usually measured in pixels, such as: 640 480, its number of pixels is 307200.

The resolution of the mobile phone is the pixel height of the screen display, and the high resolution is clear.

Mobile phone screen resolution is one of the important parameters of the mobile phone P, VGA, QVGA and other terms refer to the resolution of the mobile phone, how many points are there in the horizontal direction of a square screen, how many points are in the vertical direction, and the value after multiplication is the pixel of the screen (the pixels of the digital camera are also multiplied in this way).

However, in order to facilitate the representation of the size of the screen, it is usually represented by horizontal pixels and vertical pixels, such as 1024 768 pixels, which are very common in computer screens, and 320 480 pixels, which are very common in mobile phone screens.
