Mobile Screen

On the surface of a touchscreen phone, the touchscreen takes up the main space, and the touchscreen area typically reaches about 70 percent of the phone's surface area.When the touchscreen is divided into a "virtual screen" and a "virtual keyboard," the phone screen is not only an output device for displaying information, but also a perfect input device.The screen of mobile phone is the most important factor to decide the user experience of mobile phone. Therefore, the standard and design of the screen of mobile phone is crucial.

First, the display resolution of the mobile phone screen

At present, QVGA is one of the most common display resolution standards on mobile phone screens.In order to achieve "compatibility of software user interface" and "standardization of mobile Internet access", CQVGA display resolution standard should be adopted on mobile phone screen.

 In order to be able to better browse the web page on the phone screen, W2VGA display resolution should be used.

Second, the physical size of the phone screen

At present, the physical size of mobile phone screen is various, and there is no corresponding technical specification and market standard.Although the larger the better phone screen, but subject to a variety of factors, such as easy to carry, easy to grasp, only a few mainstream physical screen size to choose between.The physical dimensions of the mobile phone screen mainly include:2.4 "series, 2.8" series, 3.0 series, 3.2 "series, 3.5" series, 4 "series and 5" series.

Display resolution of the phone screen

Display resolution is one of the most important parameters on the phone screenWith the same screen size, the higher the display resolution, the better the display.However, the integrated mobile phone screen power consumption, mobile phone software interface compatibility, the standardization of mobile Internet and other related factors, mobile phone screen display resolution is not arbitrary, only in a few mainstream display resolution between the choice and choice.The main display resolutions of mobile phone screens mainly include the following:

One, CQVGA

 All mobile phone screens with a width of 240 pixels or 480 pixels in the vertical display state comply with the CQVGA display resolution standard.

Two, QVGA

QVGA is currently available with the popular mobile phone screen display resolution.

Three, QWVGA

Increase the height and width ratio of the QVGA screen from 4:3 to 5:3, which is QWVGA.

IV, VGA

The evolution from QVGA display resolution to VGA display resolution is the inevitable result of the computerization of mobile phones.

V, WVGA

Increase the height and width ratio of the VGA screen from 4:3 to 5:3, which is WVGA.

VI, W2VGA

Increase the height and width ratio of the VGA screen from 4:3 to 2:1, which is W2VGA.

Physical size of the phone screenThe physical size of the screen is irrelevant if the phone is used only for making phone calls and texting. If media playback, Internet browsing, office work, games and other operations are to be performed via the phone screen, then the screen size of the phone must be bigger and better, which is the same as the trend of increasing physical size of the computer screen and TV screen.The physical dimensions of the mobile phone screen and the display resolution of the mobile phone screen are closely related. Combined with various factors, the physical dimensions of the mobile phone screen mainly include the following series:One, 2.4 " SeriesThe 2.4-inch series is probably the smallest physical size of an internet-connected phone.2, 2.8 " SeriesThe 2.8-inch series will be one of the most popular screen sizes for mobile phones.3. 3.0 inch seriesThe 3.0 inch series will be one of the most popular standards for the screen size of mobile phones.Four, 3.2 " SeriesThe 3.2-inch series will be one of the mainstream standards for the screen size of mobile phones.Five, 3.5 " SeriesThe 3.5-inch series will be one of the most popular screen sizes for mobile phones.6, 4 "to 5" seriesmay be the maximum physical size of the VGA phone screen.The 5-inch series is probably the largest physical size for WVGA and W2VGA phone screens.

CQVGA display resolution (240 * X)

 At present, QVGA is the most general and universal display resolution standard. Most QVGA phones display a vertical screen with a screen width of 240 pixels. To make the phone screen display resolution more compatible, a display resolution of 240 pixels for all screen widths can be called "CQVGA" (or Compatible QVGA). CQVGA is a mobile phone screen display resolution standard specially proposed for the characteristics and requirements of mobile Internet access.

First, CQVGA mainly includes a variety of screen width of 240 pixels display resolution.

The CQVGA display resolution standard mainly includes the following display resolutions:

240 * 480 (width ratio 1:2)

240 * 432 (width ratio 9:16)

240 * 400 (width ratio 3:5)

240 * 360 (width ratio 2:3)

240 * 320 (width ratio 3:4)

240 * 240 (width ratio 1:1)

240 * 192 (width ratio 5:4)

240 * 180 (width ratio 4:3)

240 * 160 (width ratio 3:2)

All phone screens with a screen width of 240 pixels are part of the CQVGA display resolution standard.Second, various display resolutions with a screen width of 480 pixels are fully compatible with the CQVGA display resolution standard at a screen scale of 50 per cent.

 Zooming a cell phone screen that is 480 pixels wide to 50% is exactly the same as zooming a cell phone screen that is 240 pixels wide. For example, scaling a cell phone screen with a VGA display resolution to 50% becomes a QVGA screen, and the width of the cell phone screen is relative to 240 pixels, not 480 pixels.The cell phone screen, 480 pixels wide, is scaled to 50 percent, which is the CQVGA display resolution.The display resolution standard with a width of 480 pixels mainly includes the following display resolutions:

480 * 960 (width ratio 1:2)

480 * 864 (width ratio 9:16)

480 * 800 (width ratio 3:5)

480 * 720 (width ratio 2:3)

480 * 640 (width ratio 3:4)

480 * 480 (width ratio 1:1)

480 * 384 (width ratio 5:4)

480 * 360 (width ratio 4:3)

480 * 320 (width ratio 3:2)

 All phone screens with a screen width of 480 pixels, scaled to 50%, are part of the CQVGA display resolution standard.Third, the CQVGA display resolution standard is an important cornerstone of the popularization of mobile phone Internet access.

At present, an important factor affecting the mobile Internet user experience and popularity of the application is the confusion of mobile phone screen standards.For example: In the current market for mobile phones, there are a variety of display resolution, a variety of screen sizes.Therefore, to be able to display the effect of the Internet in mobile phones more standardized, all mobile phones should follow the CQVGA display resolution standard.

QWVGA display resolution (240 * 400)

Currently, QWVGA display resolution is available on only a few models of phones.

One, QWVGA is closer to a golden ratio of 0.618.

The aspect ratio of the QWVGA display resolution is 240 / 400 = 0.6, which is closer to the golden ratio of 0.618 than QVGA.

Second, play widescreen video in the horizontal display mode, the effect is better.

 More and more mobile phones support video playback feature, playing video on the QWVGA screen, the effect is better.

Third, for QWVGA touch screen mobile phone, the binary human-machine interface composed of virtual screen and virtual keyboard works better.

 In the vertical display operation mode, the display of a square virtual desktop above the phone and a virtual keyboard at the bottom of the screen can give mobile phone users a better operating experience.

VGA display resolution (480 * 640)

 VGA is a basic computer display resolution standard.With the trend of computerization of mobile phones, the change from QVGA to VGA is inevitable.

WVGA display resolution (480 * 800)

With the trend of computerization of mobile phones, the change from QWVGA to WVGA is inevitable.WVGA is also a benchmark display resolution for UMPC. 

One, closer to the gold ratio of 0.618.

 The WVGA display resolution has an aspect ratio of 480 / 800 = 0.6, which is closer to the golden ratio of 0.618 than the QVGA.Second, play widescreen video in the horizontal display mode, the effect is better.More and more mobile phones support video playback function, playing video on the WVGA screen, the effect is better.

Third, for the WVGA touch screen mobile phone, the binary man-machine interface composed of virtual screen and virtual keyboard works better.

 In the vertical display operation mode, the display of a square virtual desktop above the phone and a virtual keyboard at the bottom of the screen can be a better operation experience for mobile phone users.Fourth, for touch-screen mobile phones, you can directly browse most web pages.

 In the horizontal display operation mode, mobile phone users can directly browse the 800 pixel width of the web page, and rarely scroll to the left and right of the screen.

W2VGA display resolution (480 * 960)

 At present, the display resolution standard W2VGA (480 * 960) has never appeared on mobile phones.W2VGA is made up of 480 * 960 pixels and displays the state in a horizontal screen, twice the width of the height, so it can be called "W2VGA" or "WDVGA" because its width is larger than WVGA, so it can also be called "WWVGA."W2VGA is a kind of screen display resolution standard which I proposed specially for the computer mobile phone (PhonePc). The main purpose of W2VGA is to be able to browse the web page better on the mobile phone.

First, through the W2VGA display resolution of the phone screen, in the horizontal display status can be directly displayed 1024 pixel width of the web page.

Currently, there are two main types of screen width benchmarks for web page layout design, namely 800 pixels and 1024 pixels. In the horizontal display state, because the screen width of 960 pixels is larger than the web page width of 800 pixels, you can browse the full web page without scrolling the screen left and right, just scrolling up and down.In the horizontal display state, because the screen width of 960 pixels is basically equivalent to the width of a web page of 1024 pixels, you can browse the full web page without scrolling the screen left and right, just scrolling up and down.In web page layout design, although it is based on 1024 pixels layout, but considering the window border, scroll up and down the bar and other window interface elements occupied space, the web page width will generally be slightly less than 1024 pixels, but 960 pixels or so, so that for most web pages, 960 pixels can be displayed on all web page content, without scrolling around the web screen.When browsing a web page through a mobile phone, even if a small number of web pages are slightly larger than 960 pixels wide, there is no need to scroll around the screen, because more than 960 pixels of web page content, that is, web page content displayed in another 1024-960 = 64 pixels wide, are generally relatively minor, most are ads or other content, browsing process can not affect the user experience.

Second, through the W2VGA display resolution of the phone screen, in the horizontal display state through 150% zoom scale can display 640 pixel width of the web page.

 At a scale of 150%, you can browse 640 pixel-wide web page content directly through large pixel spacing, with little left or right scrolling.Third, the mobile phone screen using W2VGA display resolution can provide users with "VGA virtual desktop and virtual mobile phone keyboard" binary man-machine interface when the vertical screen display.

 On touch-screen phones, since there is no physical numeric keypad or physical all-letter keyboard, a binary human-machine interface consisting of a "virtual keyboard and virtual screen" must be provided.In the vertical display state of W2VGA touch screen phone, displaying a VGA virtual desktop at the top of the screen and a virtual phone keyboard at the bottom of the screen will be a very perfect binary human-machine interface design.

For example: to a certain extent, using W2VGA touch screen phone user experience to be significantly better than the VGA screen and W2VGA screen.1.68 * 2.24 = 2.8-inch VGA touchscreen mobile phone 1.68 * 2.8-inch WVGA touchscreen mobile phone 1.68 * 3.36-inch W2VGA touchscreen mobile phone

Fourth, the use of W2VGA display resolution of the phone screen, as far as possible to reduce the vertical screen display when the width of the phone, so more convenient one-handed control.

 If the use of VGA display resolution or WVGA display resolution, in order to be able to display in the horizontal screen to reach the web page to browse the applicable width and applicable point spacing, it will make the vertical screen display when the width of the phone screen is larger, rather than facilitate one-handed control of the phone. For example, if the width of the screen of the mobile phone is 9cm in horizontal display, the width of the screen of the mobile phone with VGA, WVGA and W2VGA display resolution is 6.75cm, 5.4cm and 4.5cm respectively in vertical display. It can be seen that when the screen height is the same in vertical display (that is, the screen width is the same in horizontal display), the W2GA display resolution is the minimum display width. If only from the "browsing web pages and easy one-handed control" these two factors taken into account, it is clear that the W2VGA display resolution of the actual effect is the best.

Five, why not 1024 * 600 or 1024 * 512, but 480 * 960.

From QVGA to VGA, from VGA to WVGA, W2VGA, is a natural evolutionary route for display resolution of mobile phones, not something human beings can change.The most important intrinsic reason for this evolution is the compatibility of the software user interface.1024 * X display resolution, should belong to the UMPC, MID and other portable device screen display resolution standards, rather than mobile phone screen display resolution standards, which is also a distinction between mobile phones and other portable devices (such as: MID, UMPC) an important standard. 480 * 960 is the phone screen display resolution standard maximum limit.

Other display resolution standards

 At present, the mobile phone screen in addition to a variety of CQVGA display resolution, for a variety of reasons, there are a variety of other display resolution. For example:

128*128

160*160

320*320

160*120

176*220

240*432

480*864

320*480

480*720

400*272

1024*600

 In the future, various non-standard display resolution metropolises will be replaced by more reasonable and more standard display resolutions such as CQVGA, QVGA, QWVGA, VGA, WVGA, W2VGA, etc.

One, 128 * 128 pixels display resolution.

It is mainly used on straight-panel phones and flip phones with small screen sizes. Two, 160 x 160 pixel display resolution.

Mainly used in the Palm Tero family of mobile phones.Three, 320 * 320 pixel display resolution.

Mainly used in the Palm Tero family of mobile phones. Four, 176 * 220 pixel display resolution.

 Also known as QGIF display resolution, it was mainly used on some of the early smartphones.

V, 240 * 432 pixel display resolution.The aspect ratio is 16:9 and is mainly used on some TV handsets made in Japan.

Display resolution of six, 480 * 864 pixels.The aspect ratio is 16:9 and is mainly used on some TV handsets made in Japan.

Seven, 320 * 480 pixel display resolution.With a 3:2 aspect ratio, the iPhone is a typical representation.

Eight, 480 * 720 pixel display resolution.With a 3:2 aspect ratio, the Meizu M8 phone is a typical representation.

Nine, other display resolutions.

 There are many other display resolutions on the phone, not listed here.

2.4-inch (1.44-inch) series of mobile phone screen standard

The CQVGA screen of the 2.4-inch series (i.e., 1.44 * 1.92 inch) may be the minimum size standard and display resolution standard for internet-connected mobile phones.Based on the 2.4-inch QVGA touchscreen, the 2.4-inch series of mobile phone screen standards mainly include the following:

1.1.44 * 1.92 inch QVGA screen (i.e. 2.4 inch touch screen)

2.1.44 * 1.44 inch square screen

3.1.44 * 1.08 inch rectangular screen

4.1.44 * 2.4 inch QWVGA or WVGA screen

In the vertical display operation mode, the screen width of the 2.4-inch series of mobile phones is exactly the same, both 1.44 inches, the user one-handed control of the feel is basically the same, can accept the 2.4-inch QVGA mobile phone, can accept the screen width of 1.44 inches of the 2.4-inch series of mobile phones.

One, 2.4 inch QVGA screen

 Universal application has been achieved. For example, HTC's C730 and Asus's M930w feature a 2.4-inch QVGA screen. 

2, 1.44 * 1.44 " square screen

 Many straight-panel phones and flip phones use a square screen.However, the physical size and display resolution of most square screens are small, for example, the display resolution may be 128 * 128, 160 * 160. For example, the screen size is mostly less than 2.0 inches. Screen size of 1.44 * 1.44 inches or more, display resolution of 240 * 240 pixels or more, when the mobile phone access to the Internet can achieve better results.

3, 1.44 * 1.08 " rectangular screen

For a 1.44 *.1.08 inch phone screen, it is best to use a 240 * 180 pixel display resolution instead of a 320 * 240 pixel display resolution, although both have a 4:3 aspect ratio.On straight-panel phones, the horizontal screen shows the phone screen, and if the screen size is smaller, its display resolution should be 240 * 180 instead of 320 * 240.

Quad, 1.44 * 2.4-inch QWVGA screen or WVGA screen

 If you are using a 1.44 * 2.4-inch QWVGA screen or WVGA screen, you can support a "square virtual screen and digital virtual keyboard" composed of binary human interface.1.44 * 2.4-inch QWVGA or WVGA mobile phone screen may become one of the mainstream standards of mobile phone screen.
