Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to a method and apparatus for adjusting screen resolution. Background Technology

[0002] With the widespread use of electronic products and the advancement of technology, the size and resolution of screens in electronic devices are becoming increasingly diverse. On different screens, icons or fonts of the same size may be displayed completely differently, causing inconvenience to users.

[0003] In existing technologies, to address this issue, electronic device operating systems provide scaling functions, allowing users to adapt to different screens by adjusting the scaling factor. Specifically, users need to manually control the screen's control mechanism to adjust the scaling factor, relying on their own judgment to find a suitable scaling factor for optimal screen display. In other words, the electronic device renders page data on the screen based on the resolution corresponding to that scaling factor.

[0004] However, manual adjustment requires users to continuously select the scaling factor using the control device, and most users do not have the relevant technical knowledge, which increases the difficulty of manual scaling. Summary of the Invention

[0026] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0028] Before introducing the embodiments of this disclosure, the terms and application background involved in the embodiments of this disclosure will be explained first:

[0029] Dots per inch (DPI): This usually refers to the number of printed dots per inch at logical resolution. For example, a 300 DPI printer can print 300 dots per inch, while a 600 DPI printer can print more detailed images.

[0030] Pixels per inch (PPI): This is commonly used to describe the resolution of a screen or digital image. For example, a 1920x1080 resolution screen can display approximately 96 pixels per inch, while a 3840x2160 resolution screen can display a sharper image.

[0031] Physical resolution, also known as standard resolution, refers to the original resolution of the image displayed on an LED screen, also called the true resolution. The optimal resolution of the screen, expressed mathematically as the number of rows and columns of pixels actually present on the screen, is an inherent parameter of the display and cannot be adjusted. It refers to the maximum number of pixels the screen can display.

[0032] Logical resolution: The difference between the display resolution and the physical resolution, calculated using a scaling factor. Generally, physical resolution > logical resolution, and physical resolution * scaling factor = logical resolution.

[0033] Common logical resolutions (width, height) are: (768, 1024); (1024, 640); (1280, 800); (1200, 675); (1080, 675); (1200, 750); (1366, 768); (1280, 720); (1536, 864); (1440, 810); (1536, 960); (1920, 1200); (1920, 1080); (1600, 900); (1366, 912); (1280, 850); (1332, 888); (1410, 940).

[0034] Screen size: Usually measured by the length of the diagonal of the display area, in inches, while the maximum viewable area is the maximum area of ​​graphics that the monitor can display.

[0035] With the widespread use of electronic devices and the advancement of technology, the screens of electronic devices, i.e., displays, are becoming increasingly diverse in size and resolution. On different displays, icons or fonts of the same size may appear completely different, causing inconvenience to users. Visually, the user experience is poor because the resolution is not suitable for the current viewing experience.

[0036] To address this issue, a common approach is for technicians to provide scaling functionality to the operating system of electronic devices at the factory. This allows users to adjust the scaling factor to determine the appropriate logical resolution for the current screen and render the data to be displayed at that resolution.

[0037] However, for many users, the following technical issues exist:

[0038] Firstly, the manual adjustment method is cumbersome and provides a poor user experience;

[0039] Secondly, for most users, without knowledge of scaling functions, it takes multiple attempts to determine the appropriate scaling factor to achieve the best screen rendering effect.

[0040] Based on the aforementioned technical problems, the inventor's technical concept is as follows: Although existing technologies provide scaling functions, i.e., scaling values ​​for users to choose from, users need to try randomly or iteratively to obtain a suitable scaling factor to adjust the current screen's logical resolution. If prior knowledge can be used to determine the PPI based on the monitor's size and physical resolution, and for different PPIs, the most suitable scaling factor for the screen can be determined experimentally, when the user needs to adjust the screen, the current screen's PPI can be automatically matched to obtain the most suitable scaling factor. Then, based on this scaling factor, the relevant logical resolution can be determined, thereby displaying a better display interface for the user, improving the user experience, and eliminating the need for cumbersome manual operation.

[0041] Before introducing the method embodiments of this disclosure, an application scenario involving the method of this disclosure will be described first. Figure 1 This is a schematic diagram illustrating an application scenario of a screen resolution adjustment method provided in an embodiment of this disclosure, such as... Figure 1 As shown, the application scenario includes: electronic device 11, processing unit 12 of electronic device 11, screen 13 of electronic device 11, and storage unit 14 of electronic device 11.

[0042] Among them, screen 13 can be an external screen (i.e., a display outside of electronic device 11) or an internal screen of electronic device 11 (i.e., the display of electronic device 11 itself). This application scenario is explained using an external screen as an example. The implementation of the internal screen is similar and will not be described in detail here.

[0043] In one possible implementation, the processing unit 12 obtains parameters such as the physical resolution and size of the screen 13, calculates the PPI of the screen 13, and then determines a suitable scaling factor based on the PPI and the mapping relationship between multiple PPIs and scaling factors pre-stored in the storage unit 14 of the electronic device. After that, the processing unit 12 adjusts the resolution of the screen 13 according to the scaling factor to provide the user with a better screen display method.

[0044] The technical solutions of this disclosure will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0045] It is worth noting that the application field of the screen resolution adjustment method and device disclosed herein is not limited, and may include the field of screen resolution adjustment technology. The executing subject of this disclosure is an electronic device, specifically a mobile phone, tablet, computer, server, or other such device. In some implementations, the electronic device can connect to an external screen or may have its own built-in screen.

[0046] Figure 2 Flowchart of the screen resolution adjustment method provided in this embodiment of the disclosure Figure 1 ,like Figure 2 As shown, the method may include the following steps:

[0047] Step 21: Determine the target PPI on the screen of the electronic device;

[0048] In this step, the target PPI is the original PPI of the screen of the electronic device.

[0049] In other words, the original PPI of the screen can be the PPI corresponding to the physical resolution designed before leaving the factory, which is related to the size of the screen.

[0050] Step 22: Determine the target scaling factor of the screen based on the target PPI and the preset mapping relationship. The mapping relationship is used to indicate the scaling factor corresponding to multiple PPI threshold ranges respectively.

[0051] In this step, the electronic device has a built-in mapping relationship for indicating the scaling factor corresponding to multiple PPI threshold ranges. This mapping relationship can be determined through multiple experiments, which can ensure that when the target PPI is placed within the corresponding PPI threshold range, its corresponding scaling factor is a scaling factor suitable for the current screen.

[0052] In one possible implementation, if the target PPI is determined to be 270, the various PPI threshold ranges can be traversed in the mapping relationship. For example, if a PPI threshold range is matched to be less than 290 and greater than or equal to 230, then the target scaling factor corresponding to the target PPI is determined to be the scaling factor 2.0 corresponding to that PPI threshold range, and the target scaling factor of the screen is determined to be 2.0.

[0053] Optionally, the screen may include a built-in screen and / or an external screen.

[0054] In practical applications, electronic devices can include one or more screens, i.e., the built-in screen of the electronic device, such as laptops and mobile phones; electronic devices can also connect to other displays wirelessly or via wired means, i.e., as external screens for the electronic device, for example, the host of a desktop computer can be connected to a monitor via a data cable.

[0055] Accordingly, the mapping relationships include: a first mapping relationship for the built-in screen and / or a second mapping relationship for the external screen. The first mapping relationship is the scaling factor corresponding to multiple PPI threshold ranges determined when the DPI corresponding to the logical resolution of the built-in screen is closer to the second value than the first value. The second mapping relationship is the scaling factor corresponding to multiple PPI threshold ranges determined when the DPI corresponding to the logical resolution of the external screen is closer to the first value than the second value.

[0056] It should be understood that since there are built-in screens and external screens, there are their own mapping relationships, namely the first mapping relationship for built-in screens and the second mapping relationship for external screens. The establishment of these two mapping relationships requires that after scaling the physical resolution by the corresponding scaling factor, the DPI corresponding to the logical resolution should be close to the second value and the first value, respectively. Multiple experiments have demonstrated that the screen display effect is better when the values ​​are close to the corresponding values ​​(this example is given in step 23, and the number of times will not be repeated).

[0057] Optionally, DPI can be calculated as follows:

[0058]

[0059] Where C is the width of the logical resolution, D is the height of the logical resolution, and E is the diagonal size of the screen.

[0060] In one possible implementation, the first value is less than the second value; the first value is 90 and the second value is 120.

[0061] Optionally, as an example, the first mapping relationship corresponding to the built-in screen includes:

[0062] The PPI threshold range is greater than or equal to 290, corresponding to a scaling factor of 2.5;

[0063] The scaling factor corresponding to the PPI threshold range of less than 290 and greater than or equal to 230 is 2;

[0064] The scaling factor corresponding to the PPI threshold range of less than 230 and greater than or equal to 200 is 1.666;

[0065] The scaling factor corresponding to a PPI threshold range of less than 200 and greater than or equal to 170 is 1.5;

[0066] The scaling factor corresponding to a PPI threshold range of less than 170 and greater than or equal to 140 is 1.25.

[0067] The PPI threshold range is less than 140 and greater than or equal to 0, corresponding to a scaling factor of 1.

[0068] That is, Table 1 is a schematic table of the first mapping relationship corresponding to the built-in screen provided in the embodiments of this disclosure, as shown in Table 1:

[0069] Table 1:

[0070] Greater than or equal to 290 2.5 Less than 290 and greater than or equal to 230 2 Less than 230 and greater than or equal to 200 1.666 Less than 200 and greater than or equal to 170 1.5 Less than 170 and greater than or equal to 140 1.25 Less than 140 and greater than or equal to 0 1

[0071] Generally, the scaling factor should meet the condition: scale = x / 8, where scale is the scaling factor and x is any natural number. The above scaling factor basically meets this condition (the same applies to the second mapping relationship diagram below). However, when the scaling factor is 1.666, in order to ensure that the logical resolution calculated later is one of the common logical resolutions (that is, to ensure that the horizontal and vertical logical resolutions are integers after scaling as much as possible), the corresponding scaling factor is set to 1.666 when the PPI threshold range is less than 230 and greater than or equal to 200.

[0072] Optionally, the second mapping relationship corresponding to the external screen includes:

[0073] The PPI threshold range is greater than or equal to 175, corresponding to a scaling factor of 2;

[0074] The scaling factor corresponding to the PPI threshold range of less than 175 and greater than or equal to 150 is 1.875;

[0075] The scaling factor corresponding to a PPI threshold range of less than 150 and greater than or equal to 125 is 1.5;

[0076] The scaling factor corresponding to a PPI threshold range of less than 125 and greater than or equal to 100 is 1.25;

[0077] The PPI threshold range is less than 100 and greater than or equal to 0, corresponding to a scaling factor of 1.

[0078] That is, Table 2 is a schematic table of the second mapping relationship corresponding to the built-in screen provided in the embodiments of this disclosure, as shown in Table 2:

[0079] Table 2:

[0080]

[0081]

[0082] It should also be understood that since the screen can be an internal screen and / or an external screen, in practical applications, adjusting the screen resolution can involve one or more internal screens, one or more external screens, or one or more internal screens and one or more external screens.

[0083] Step 23: Adjust the screen's logical resolution according to the screen's physical resolution and the target scaling factor.

[0084] In this step, the physical resolution is the original resolution of the screen when it was manufactured. After the target scaling factor is determined in the above steps, the physical resolution is scaled based on the target scaling factor to adjust the logical resolution of the screen.

[0085] Optionally, step 23 can be implemented as follows:

[0086] Step 1: Adjust the ratio of the physical resolution width to the target scaling factor to the logical resolution width;

[0087] Step 2: Adjust the ratio of the physical resolution height to the target scaling factor to the logical resolution height.

[0088] As an example, Table 3 is a schematic table illustrating the scaling of the built-in screen provided in the embodiments of this disclosure (also showing a DPI closer to the second value, such as 120, with a size of 14' as an example), as shown in Table 3:

[0089] Table 3:

[0090] 1920，1080 157.35 1.25 1536，864 125.88 2160，1440 185 1.5 1440，960 123.62 2560，1440 209.8 1.666 1536，864 125.88 3840，2160 314.7 2.5 1536，864 125.88

[0091] For example, if the width of the physical resolution is 1920, then the width of the logical resolution is 1920 / 1.25 = 1536; if the height of the physical resolution is 1080, then the height of the logical resolution is 1080 / 1.25 = 864; other examples follow the same principle.

[0092] As an example, Table 4 is a schematic table illustrating the scaling of the external screen provided in the embodiments of this disclosure (also showing a DPI closer to a first value, such as 90), as shown in Table 4:

[0093] Table 4:

[0094]

[0095]

[0096] For example, if the width of the physical resolution is 1920, then the width of the logical resolution is 1920 / 1 = 1920; if the height of the physical resolution is 1080, then the height of the logical resolution is 1080 / 1 = 1080; other examples follow the same principle.

[0097] It should be understood that the calculation process of PPI in Tables 3 and 4 is given in the following examples.

[0098] Optionally, the specific module that adjusts the screen's logical resolution to achieve screen scaling can be the computer's underlying Graphics module.

[0099] The screen resolution adjustment method provided in this disclosure is applied to an electronic device. This method determines a target PPI on the screen of the electronic device, and determines a target scaling factor for the screen based on the target PPI and a preset mapping relationship. This mapping relationship indicates the scaling factors corresponding to multiple PPI threshold ranges. The logical resolution of the screen is adjusted according to the physical resolution of the screen and the target scaling factor. In this technical solution, after determining the target PPI, a suitable scaling factor is automatically matched from the pre-configured scaling factors corresponding to the PPI threshold ranges, thereby automatically setting a suitable physical resolution for the user, thus improving the user experience and avoiding tedious manual operations.

[0100] Based on the above embodiments, Figure 3 Flowchart of the screen resolution adjustment method provided in this embodiment of the disclosure Figure 2 ,like Figure 3 As shown, step 21 above may include the following steps:

[0101] Step 31: Obtain the screen's physical resolution and diagonal size;

[0102] In this step, the screen's physical resolution and diagonal size can be obtained from the device information.

[0103] For example, the above can be used to obtain some screen physical resolution and screen diagonal size.

[0104] As an example, Table 5 is a schematic table illustrating the physical resolution and size of the built-in screen provided in the embodiments of this disclosure, as shown in Table 5:

[0105] Table 5:

[0106]

[0107]

[0108] As an example, Table 6 is a schematic table illustrating the physical resolution and size of the external screen provided in the embodiments of this disclosure, as shown in Table 6 (same as Table 4):

[0109] Table 6:

[0110] 24' 1920，1080 27' 1920，1080 27'2K 2560，1440 27'4K 3840，2160

[0111] Step 32: Determine the target PPI based on the physical resolution and diagonal size.

[0112] In this step, after determining the physical resolution and diagonal size as described above, the target PPI for the corresponding screen is determined.

[0113] Optionally, the PPI can be calculated as follows:

[0114]

[0115] Where A is the width of the physical resolution, B is the height of the physical resolution, and E is the diagonal size of the screen.

[0116] For example, if the width of the physical resolution is 1920, the height of the physical resolution is 1080, and the size is 14', the target PPI is 157.35 according to the above PPI calculation formula; if the width of the physical resolution is 1920, the height of the physical resolution is 1080, and the size is 24', the target PPI is 91.79 according to the above PPI calculation formula; other examples are similar and will not be listed here.

[0117] The screen resolution adjustment method provided in this disclosure obtains the screen's physical resolution and diagonal size, and then determines the target PPI based on the physical resolution and diagonal size. This technical solution achieves the determination of the current screen's PPI.
