Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a method and apparatus for dynamically adjusting resolution. Background Art

[0002] With the gradual maturity of display technologies and the gradual reduction of costs, the demand for high-end display devices has increased significantly. Currently, with the popularization of high-quality content such as Dolby Ultra HD videos and Ultra HD games, the resolution of display devices has been greatly improved. Ultra HD display devices have broad market prospects in the future.

[0003] However, ultra HD display devices still have many disadvantages as follows. (1) Ultra HD display devices are prone to waste computing power resources, power consumption resources, and transmission resources. Not all usage scenarios and applications of ultra HD display devices require ultra HD picture quality. For example, in office scenarios such as text code classes, using ultra HD picture quality does not have an advantage. Since the computer display adapter outputs signals at the highest resolution and refresh rate for a long time, the rendering computing power of the display adapter is in a high-load state, resulting in unnecessary power consumption waste. (2) Due to the high resolution, the desktop display ratio is seriously imbalanced, affecting daily office efficiency. To achieve ultra HD picture quality, a display device requires more pixel points, which will inevitably result in a reduced pixel pitch, smaller display content, and problems such as overly small text, icons, and images. These problems hinder the user experience of viewing the screen and affect daily office use. (3) The display resolution of multiple display devices using the Multi Stream Transport (MST) function is limited. The multi-stream transport function needs to meet the resolution of the first main display device, and the remaining amount can be allocated to the second and third display devices, resulting in the first display device being able to display images with better picture quality, while the second and third display devices can only display images with rough picture quality, bringing a bad user experience to users using the multi-stream transport function.

[0004] Regarding the problem of the overly small display ratio of ultra HD monitors, currently, the scaling function provided by the operating system is used to perform ratio scaling in a software manner. However, this scaling function cannot be compatible with all software and applications. Moreover, when the operating system changes the resolution, only the display result of the display device is scaled, and the actual bandwidth of the transmitted video is not reduced. With the operating system power consumption and computing power still remaining at the highest level, serious resource waste will occur.

[0005] Therefore, there is a need for a method and apparatus for dynamically adjusting resolution to achieve the purposes of reducing the power consumption of the operating system and display device, maintaining good picture quality, and improving the comfort of viewing the screen. Summary of the Invention

[0006] The following disclosure is merely exemplary and is not intended to be limiting in any way. In addition to the described aspects, embodiments, and features, other aspects, embodiments, and features will be apparent by reference to the drawings and the following detailed description.

Accordingly, the following disclosure is not intended to be a necessary feature of the claimed subject matter nor is it intended to be used in determining the scope of the claimed subject matter.

[0007] Therefore, the main objective of the present invention is to provide a method and apparatus for dynamically adjusting the resolution. By instructing to reset the communication channel between the source device (such as a host device like a computer display adapter) and the display device, the resolution of the display device is dynamically adjusted to achieve the purpose of reducing communication data and bandwidth, reducing the data generation amount of the source device, and reducing the overall power consumption of the display system while maintaining good image quality.

[0008] The present invention proposes a method for dynamically adjusting the resolution for use in a display device, including: when receiving a scaling ratio data instruction, performing a ratio reduction operation on the original resolution of a display screen of the display device by a microcontroller of the display device according to the scaling ratio data instruction to obtain a target resolution; replacing the original resolution at a resolution storage location in an extended display identification data (EDID) by the microcontroller with the target resolution to allow a source device to read; receiving, by the microcontroller, an image data generated by the source device according to the target resolution; performing a ratio magnification operation on the target resolution by the microcontroller according to the scaling ratio data instruction to obtain a screen resolution; and setting, by the microcontroller, the original resolution of the display screen to the screen resolution to display the image data.

[0009] In some embodiments, the scaling ratio data instruction includes a value for indicating the scaling ratio, and the ratio reduction operation further includes: dividing the original resolution by the value and performing a floor operation to generate a first resolution; when the first resolution is not greater than the original resolution, setting the first resolution as the target resolution; and when the first resolution is greater than the original resolution, setting the original resolution as the target resolution.

[0010] In some embodiments, the value is a positive number.

[0011] In some embodiments, the scaling ratio data instruction includes a value for indicating the scaling ratio, and the downscaling operation further includes: performing a floor operation on the value to generate a first value; and multiplying the target resolution by the first value to generate the screen resolution.

[0012] In some embodiments, when the screen resolution is less than the original resolution, a display instruction is transmitted to the display screen, where the display instruction is to indicate to display the image data at the center of the display screen and turn off the driving power of the edge area corresponding to the part exceeding the screen resolution or display a low-power color in the edge area.

[0013] In some embodiments, the method further includes: storing the original resolution in another storage location in the extended display identification data; and when the source device cannot read the target resolution, replacing the target resolution at the resolution storage location with the original resolution.

[0014] In some embodiments, the image data has a target resolution.

[0015] In some embodiments, after replacing the original resolution with the target resolution, the microcontroller resets the transmission channel between the source device and the display device.

[0016] The present invention provides a device for dynamically adjusting the resolution, including: one or more processors; and one or more computer storage media storing computer-readable instructions, where the processor uses the computer storage media to perform: when receiving a scaling ratio data instruction, performing a downscaling operation on an original resolution of a display screen according to the scaling ratio data instruction to obtain a target resolution; replacing the original resolution at a resolution storage location in an extended display identification data with the target resolution to allow a source device to read; receiving an image data generated by the source device according to the target resolution; performing an upscaling operation on the target resolution according to the scaling ratio data instruction to obtain a screen resolution; and setting the original resolution of the display screen to the screen resolution to display the image data.

On the contrary, when the element is referred to as being "directly connected" or "directly coupled" to another element, there are no intermediate elements.

[0049] An embodiment of the present invention provides a method and device for dynamically adjusting the resolution. By instructing to reset the communication channel between the source device (such as a host device like a computer display adapter) and the display device, the resolution of the display device is dynamically adjusted, so as to achieve the purpose of reducing communication data and bandwidth, reducing the data generation amount of the source device, and reducing the overall power consumption of the display system under the condition of maintaining good image quality.

[0050] Figure 1FIG. 0 is a schematic diagram of a system 100 for dynamically adjusting resolution according to an embodiment of the present invention. The system 100 includes a source device 110 and a display device 120. The source device 110 is used to output image data, and its type ranges from a small host device (e.g., a computer host with a display adapter) to a large host system (e.g., a large server).

[0051] The display device 120 can be connected to the source device 110 by a transmission cable compliant with the regulations of the Video Electronics Standards Association (VESA), where the transmission cable can include unidirectional and bidirectional signal transmission channels compliant with the VESA standard. The display device 120 at least includes a microcontroller 122 and a display screen 124. The microcontroller 122 can receive image data from the source device 110 and transmit the image data to the display screen 124 for display.

[0052] The microcontroller 122 can receive a scaling ratio data instruction input by a user, where the scaling ratio data instruction can include an instruction directly input through the display device 120 or an indirect instruction input through other devices.

[0053] The display device 120 can present an on-screen display (OSD) interface to the user, and the OSD interface can provide multiple selectable scaling ratio data. The user can directly input a scaling ratio data instruction through the OSD interface to select the desired scaling ratio data.

[0054] In addition, the user can also input a scaling ratio data instruction through the source device 110 or other devices. For example, the microcontroller 122 of the display device 120 can provide a dedicated application programming interface (API) to communicate with the source device 110 or other devices. Therefore, the user can input a scaling ratio data instruction on the source device 110 or other devices to select the desired scaling ratio data.

[0055] In one embodiment, the microprocessor 122 can include a downscaling module 1222, a data storage module 1224, and an upscaling module 1226.

[0056] The downscaling module 1222 can perform a downscaling operation on an original resolution of the display screen 124 according to the scaling ratio data instruction received by the microprocessor 122 to obtain a target resolution.

[0057] In one embodiment, the ratio reduction module 1222 is disposed outside the microprocessor 122, and the ratio reduction module 1222 is electrically coupled to the microprocessor 122.

[0058] The data storage module 1224 replaces the original resolution at a resolution storage location in an Extended Display Identification Data (EDID) with a target resolution to allow the source device 110 to read. The EDID is a description of the display capabilities of a display device, which is a standard information format for display devices formulated by the VESA association, just like the ID card of a display device. The EDID can include information such as the display device name, serial number, and original resolution. Its purpose is to inform the source device 110 of the capabilities that the display device 120 can support before displaying an image, to ensure normal transmission and display of content.

[0059] In one embodiment, after the data storage module 1224 replaces the original resolution at the resolution storage location with the target resolution, it stores the original resolution in another storage location in the EDID. When the source device 110 cannot read the target resolution, the data storage module 1224 can replace the target resolution at the resolution storage location back with the original resolution.

[0060] In another embodiment, after the original resolution is replaced with the target resolution, the microprocessor 122 sets an HPD interrupt and pulls down the hot plug pin of the display device 120 for a period of time, so that the display adapter of the source device 110 disconnects the transmission channel from the display device 120 and stops obtaining the EDID. The microprocessor 122 then pulls up the hot plug pin to reset the transmission channel between the display adapter of the source device 110 and the display device 120. After the transmission channel is reset, the display adapter of the source device 110 will read and identify the EDID after the resolution is replaced. After the display adapter of the source device 110 obtains the target resolution in the EDID, it will generate image data according to the number of pixels of the target resolution, thereby realizing the function of dynamically adjusting the resolution of the display device.

[0061] The ratio amplification module 1226 receives an image data generated by the source device 110 according to the target resolution, and performs a ratio amplification operation on the target resolution according to a value included in the scaling ratio data instruction indicating the scaling ratio to obtain a screen resolution.

[0062] The microcontroller 122 sets the original resolution of the display screen 124 to the screen resolution and displays the above-mentioned image data.

[0063] It should be noted that although the microcontroller 122 is in Figure 1In the figure, the display screen 124 is included in the display device 120 as an example, but the present invention should not be limited thereto. In one embodiment, the microcontroller 122 may be a device outside the display device 120 and may be connected to the display device 120 through a High Definition Multimedia Interface (HDMI).

[0064] It should be understood that Figure 1 The illustrated source device 110 and display device 120 are examples of the architecture of the system 100 for dynamically adjusting the resolution. Figure 1 Each of the illustrated devices may be implemented via any type of electronic device, such as the electronic device 800 described with reference to Figure 8 as shown Figure 8 as shown

[0065] The following will detail how the downscaling module 1222 performs a downscaling operation and how the upscaling module 1226 performs an upscaling operation in detail.

[0066] Figure 2 is a flowchart showing the operation of the downscaling module 1222 performing a downscaling operation according to an embodiment of the present invention. As shown in the figure, it is assumed that the display device provides selectable scaling ratio data [Ratio Data 1, RatioData 2, Ratio Data 3, …, Ratio Data n]. The downscaling module 1222 may receive the scaling ratio data instruction 202 and obtain a value Scaling Ratio included in the scaling ratio data instruction 202 for indicating the scaling ratio. The value Scaling Ratio can be represented by the following formula

[0067] Scaling Ratio = {Ratio Data[n]|n = 1, 2, 3...}

[0068] (Ratio Min ≤ Ratio Data[n] ≤ Ratio Max)

[0069] where the value Scaling Ratio may be a positive number X, and each scaling ratio data Ratio Data[n] is within a range between Ratio Min and Ratio Max. In one embodiment, Ratio Min may be set to 1 and RatioMax may be set to 3. In another embodiment, each scaling ratio data Ratio Data[n] is not limited to an integer or a decimal.

[0070] The microprocessor can obtain the original resolution Y of the display screen, where the original resolution is equal to the physical resolution of the display screen, and is divided into the horizontal pixels Y H and the vertical pixels Y V .

[0071] The scaling-down module 1222 divides the original resolution Y by the value X and performs a floor operation to generate a first resolution Z, where the first resolution Z is composed of the horizontal pixels Z H and the vertical pixels Z V and can be represented by the following formula:

[0072] Z H = Rounddown(Y H / X)

[0073] Z V = Rounddown(Y V / X)

[0074] When the first resolution is not greater than the original resolution, the scaling-down module 1222 sets the first resolution as the target resolution. When the first resolution is greater than the original resolution, the scaling-down module 1222 sets the original resolution as the target resolution.

[0075] After setting the target resolution, the scaling-down module 1222 transmits the target resolution to the data storage module 1224. Subsequently, the source device will re-identify and confirm the target resolution with the display device to generate and transmit image data.

[0076] Figure 3 is a flowchart showing the operation of the scaling-up module 1226 performing a scaling-up operation according to an embodiment of the present invention.

[0077] As shown in the figure, the scaling-up module 1226 can obtain the target resolution Z from the scaling-down module 1222 or the data storage module 1224. The target resolution Z can be represented by the following formula:

[0078] Z = {Z H , Z V}

[0079] where Z H represents the horizontal pixels, Z VRepresents vertical pixels. Compared with the image data with the original resolution, the number of pixels in the image data with the target resolution has significantly decreased. Since the physical resolution of the display screen is fixed, when the resolution of the image data needs to be presented according to the size of the display screen, the number of pixels needs to be mapped and enlarged in a certain proportion. In the present invention, the target resolution is enlarged by an integer multiple equal to a first value X, where this first value is obtained by performing a floor operation on a value used to indicate the scaling ratio in the scaling ratio data instruction 202 included in Figure 2 When the first value is larger, the more pixel points the image data is mapped to and the larger the text and image displayed, so as to improve the viewing comfort of the viewing angle. The first value X can be represented by the following formula:

[0080] X = Rounddown[Scaling Ratio]

[0081] The screen resolution S is generated by multiplying the target resolution Z by the first value X. The number of pixel points presented on the display screen includes the horizontal pixel S H and the vertical pixel S V . The screen resolution S, the horizontal pixel S H and the vertical pixel S V can be represented by the following formula:

[0082] S = {S H , S V}

[0083] S H = Z H * X

[0084] S V = Z V * X

[0085] From the above formula, it can be known that the screen resolution is enlarged by multiplying the target resolution by an integer multiple of the first value. The advantage of using an integer multiple is that the edge of the displayed image data is enlarged in integer multiples, and there will be no excessive gray levels that cause the image edge to be blurred, and a certain clarity of the image data can be maintained. As Figure 4 shown, 410 is the edge area of the screen resolution obtained by multiplying the target resolution by an integer multiple of the first value. 420 shows that there is excessive gray level in the edge area, where the excessive gray level is a low-contrast performance and will reduce the clarity of the displayed image data.

[0086] The mapping and enlargement relationship between the target resolution and the screen resolution can be shown in Table 1.

[0087]

[0088] Table 1

[0089] In one embodiment, when the screen resolution is equal to the original resolution, all the pixel points of the display screen will be filled and displayed. When the screen resolution is less than the original resolution, the microprocessor will transmit a display instruction to the display screen, where the display instruction is to indicate to display the image data at the screen resolution in the center of the display screen and turn off the drive power of the corresponding edge area exceeding the screen resolution or display a low-power color in the edge area.

[0090] Figure 5 It is a schematic diagram of turning off the drive power of the edge area or displaying a low-power color in the edge area according to an embodiment of the present invention. As Figure 5 shown, the image data is displayed in the display area in the center of the display screen, and the drive power of the edge area exceeding the screen resolution will be turned off or a low-power color will be displayed in the edge area. The advantage of adopting the method of turning off the drive power of the edge area or displaying a low-power color in the edge area is that on the one hand, it ensures that the display area has an integer multiple of the target resolution, and on the other hand, since there is no need to consume power to drive the edge area without display, the power consumption of the display device is reduced. In addition, since the image data transmitted by the source device is generated according to the target resolution, the purpose of reducing the transmission bandwidth and power consumption between the source device and the display device can be achieved.

[0091] Figure 6 It is a flowchart showing the method 600 for dynamically adjusting the resolution according to an embodiment of the present invention. This method 600 is executed by the display device 120 as shown in Figure 1 shown.

[0092] In step S605, when receiving a scaling ratio data instruction, a microcontroller of the display device performs a ratio reduction operation on the original resolution of a display screen of the display device according to the scaling ratio data instruction to obtain a target resolution. In one embodiment, the scaling ratio data instruction includes a value for indicating the scaling ratio, and the value is a positive number. The ratio reduction operation further includes: the microcontroller divides the original resolution by the value and performs a floor operation to generate a first resolution. When the first resolution is not greater than the original resolution, the microcontroller sets the first resolution as the target resolution; and when the first resolution is greater than the original resolution, the microcontroller sets the original resolution as the target resolution.

[0093] Next, in step S610, the microcontroller replaces the original resolution at a resolution storage location in an extended display identification data (EDID) with the target resolution to allow a source device to read.

[0094] In step S615, the microcontroller receives an image data generated by the source device according to the target resolution, where the image data has the target resolution.

[0095] In step S620, the microcontroller performs a scaling-up operation on the target resolution according to the scaling ratio data instruction to obtain a screen resolution. In one embodiment, the scaling-up operation further includes: the microprocessor performs a floor operation on a value to generate a first value. The microprocessor multiplies the target resolution by the first value to generate the screen resolution.

[0096] In step S625, the microcontroller sets the original resolution of the display screen to the screen resolution to display the image data.

[0097] In one embodiment, when the screen resolution is less than the original resolution, the microprocessor transmits a display instruction to the display screen, where the display instruction is to indicate to display the image data at the center of the display screen and turn off the driving power of the corresponding edge area exceeding the screen resolution or display a low-power color in the edge area.

[0098] Figure 7 is a schematic diagram showing the resolution scaling according to an embodiment of the present invention. In Figure 7 it, taking the original resolution of a display screen as 6K (6144*3456) and the value indicating the scaling ratio in the scaling ratio data instruction as 1, 2, 2.2 as examples for illustration.

[0099] As shown in the figure, when the values indicating the scaling ratio are 1, 2, 2.2, the target resolution 1, target resolution 2, and target resolution 3 can be expressed by the following formulas:

[0100] Target resolution 1 = [6144*3456] / 1 = [6144*3456]

[0101] Target resolution 2 = [6144*3456] / 2 = [3072*1728]

[0102] Target resolution 3 = [6144*3456] / 2.2 = [{2792.7272...}*{1570.909090...}]

[0103] For target resolution 3, since target resolution 3 is not reduced by an integer multiple ratio, the microcontroller also performs a floor operation on target resolution 3, as expressed by the following formula:

[0104] Rounddown(Target resolution 3) = [2792*1570]

[0105] After obtaining the target resolution 1, target resolution 2, and target resolution 3 through operations, the microprocessor then magnifies the target resolution 1, 2, and 3 by an integer ratio to obtain the screen resolution 1, screen resolution 2, and screen resolution 3, as represented by the following formula:

[0106] Screen resolution 1 = Target resolution 1 * Value 1 = [6144 * 3456] * 1 = 6144 * 3456

[0107] Screen resolution 2 = Target resolution 2 * Value 2 = [3072 * 1728] * 2 = 6144 * 3456. Since Value 3 is 2.2, the microprocessor will perform a floor operation on Value 3, as represented by the following formula:

[0108] Rounddown(Value 3) = 2

[0109] Therefore, the screen resolution 3 is expressed as follows:

[0110] Screen resolution 3 = Target resolution 3 * Rounddown(Value 3) = [7892 * 1570] * 2

[0111] = 5584 * 3140

[0112] As Figure 7 shown, when the display screen displays image data at the screen resolution 3, since the display screen only displays at the pixel size of 5584 * 3140 for the screen resolution 3, there will be an edge area with a pixel size of 6144 * 316 + 3140 * 560 on the display screen.

[0115] As described above, the method and device for dynamically adjusting the resolution proposed by the present invention use a target resolution smaller than the original resolution to generate image data, significantly reducing the amount of image generation, the computing power and power consumption of the display adapter of the source device, and the amount of image data transmitted from the source device, achieving the purpose of reducing the power consumption of the entire transmission channel. In addition, in the display device, directly replacing the original resolution in the EDID with the target resolution is more flexible for resolution switching and selection, and can reduce the storage capacity of excessive EDIDs, reducing the cost of storage hardware.
