[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0033] The technical solution provided in this application is mainly applied to a control device (such as a multimedia player box) that controls a display screen to display images. Specifically, the control device receives image data (such as the resolution of the image displayed on the display screen) configured from the input device through communication connections established with the input device (such as a terminal device such as a computer, a mobile phone, etc.) and the display screen (LED screen), and converts the image data into an image (such as a static image, a dynamic image, etc.) that can be displayed on the display screen, thereby realizing the function of the control device to control the display screen to display images. Taking the control device as a multimedia player box and the input device as a computer as an example, illustratively, the user configures the image data to be played on the computer, such as adjusting the resolution of the image displayed on the display screen, the size of the image displayed on the display screen, etc. After the image data configuration is completed, the computer sends the configured image data to the multimedia player box. After receiving the configured image data, the multimedia player box processes the configured image data, converts the image data into image data that can be output on the display screen, and controls the display screen to display the image data. At present, the multimedia player box is a very important content playback medium, which is widely used in fields that require display screens, such as commercial displays, advertising media, etc. that use car screens, lamp pole screens, etc. to achieve image playback.

[0034] In the prior art, in order to meet the various requirements of users for the resolution size of the display screen, a part of the resolution list (such as 1280×720, 1920×1080, 4096×2160, etc.) is preset inside the multimedia player box. However, the preset resolution often does not meet the user's requirements for the resolution size. Therefore, this solution provides a method, device, system and storage medium for adjusting the resolution of the LED display screen, which is used to realize that the multimedia player box can automatically adjust the resolution size of the LED display screen output by the control device according to the actual resolution information configured by the user for the display screen.

[0035] like Figure 1 As shown, Figure 1 A schematic diagram of a system for automatically adjusting the resolution of an LED display screen provided in an embodiment of the present application, the system comprising: a control device 100, an input device 200 and a display screen 300.

[0036] As an example, the control device 100 can be a multimedia playback box for adjusting the resolution of a display screen; the input device 200 can be a device for taking the actual physical resolution of a display screen configured by a user (i.e., a first resolution) as configuration information, and sending the configuration information to a terminal device of the control device 100, such as a computer, a mobile phone, or a Pad; the display screen 300 is a LED display screen (Light Emitting Diode Display).

[0037] As an example, the control device 100 can establish a communication connection with the input device 200, and the communication connection can be a wireless communication connection or a wired communication connection. For example, the control device 100 can act as a wireless access point (Access Point, AP), and the input device 200 can act as a station (Station, STA), and establish a communication connection with the control device 100 by accessing the wireless local area network established by the control device 100. For example, the control device 100 and the input device 200 can also be connected to the same wireless local area network as STAs for communication. For example, the control device 100 can also establish a wired communication connection with the input device 200 through a network cable interface, which is not limited in the embodiments of the present application.

[0038] As an example, the control device 100 can establish a communication connection with the display screen 300. Exemplarily, the control device 100 can establish a communication connection with the display screen 300 through an interface such as a VGA (Video Graphics Array) interface or an HDMI (Video Graphics Array). Through the communication connection, the control device 100 can configure image data to the display screen 300. For example, the image data can be configuration information for controlling the display screen 300 to display an image, such as timing parameters.

[0039] like Figure 2 As shown, Figure 2The structural diagram of a control device 100 provided in an embodiment of the present application is shown, and the control device 100 includes: a first communication interface, a second communication interface, a processing module, a sending module and a receiving module. Among them, the processing module is connected to the first communication interface, the second communication interface, the sending module and the receiving module respectively. Exemplarily, the first communication interface can be a wireless network interface, or an Ethernet interface, or of course a Bluetooth interface, and the control device 100 can establish a communication connection with other devices (such as an input device 200) through the first communication interface. The second communication interface can be a VGA interface or an HDMI interface, and the control device 100 can establish a communication connection with other devices (such as a display screen 300) through the second communication interface. The processing module of the control device 100 can be used to determine whether the control device 200 can support the first resolution in the display screen configuration information controlled by the control device in the input device 200, and can also be used to generate multiple timing parameters corresponding to the display screen 300. The sending module can be used to configure image data (such as resolution size, etc.) to the display screen 300. The receiving module can be used to receive configuration information from the input device 200, such as resolution size, etc.

[0040] In the embodiment of the present application, the specific structure of the execution subject of a method for adjusting the resolution of an LED display screen is not particularly limited in the embodiment of the present application, as long as it can communicate according to the method for adjusting the resolution of an LED display screen in the embodiment of the present application by running a program that records the code of the method for adjusting the resolution of an LED display screen in the embodiment of the present application. For example, the execution subject of a method for adjusting the resolution of an LED display screen provided in the embodiment of the present application can be a functional module in a control device that can call and execute a program, or a device for automatically adjusting the resolution of an LED display screen in a control device, such as a chip. This application does not limit this.

[0041] The following embodiments are described by taking a method for adjusting the resolution of an LED display screen in which the execution subject is a control device and an input device as an example.

[0042] like Figure 3 As shown, Figure 3 An interactive schematic diagram of a method for adjusting the resolution of an LED display screen provided in an embodiment of the present application is shown, the method comprising:

[0043] Step 410: The input device sends the first resolution configured for the display screen controlled by the control device to the control device through the communication connection between the control device and the input device. Correspondingly, the control device obtains the first resolution configured for the display screen controlled by the control device from the input device.

[0044] The communication connection between the control device and the input device may be a wireless communication connection or a wired communication connection. The communication connection between the control device and the input device may refer to the description of the above embodiment, which will not be repeated here.

[0045] Among them, the first resolution is used to control the device to control the display screen to display an image on the display screen in the form of the first resolution. It should be explained that the first resolution is the actual screen physical resolution of the control display screen. It can be understood that the resolution specifies the number of pixels in the image, that is, the clarity of the image. For example, the higher the resolution of the image, the more pixels are contained in the image, that is, the clearer the image is.

[0046] As an example, the first resolution is a resolution of a display when displaying an image, which can be selected from a resolution list preset in the control device. Among them, the resolution list can store a variety of commonly used resolutions. The embodiment of the present application does not limit the form of storing resolution information in the resolution list. Optionally, the resolution list can store information in a table form, such as the resolution list shown in Table 1:

[0047] Table 1 Resolution list

[0048] Serial number Resolution Resolution 1 1280×720 Resolution 2 1920×1080 Resolution 3 2560×1440 Resolution 4 3840×2160 ... ...

[0049] For example, the resolution list stores first resolutions of 1280×720, 1920×1080, 2560×1440, 3840×2160, etc. By providing the commonly used first resolutions by the control device, the user can conveniently configure the resolution size of the display screen controlled by the control device.

[0050] As another example, the first resolution may be a first resolution customized on the input device according to user requirements, for example, the customized first resolution may be 1000 × 1000. Optionally, the first resolution may also be a first resolution stored in a resolution list.

[0051] Step 420: When the control device is capable of supporting the first resolution, the control device determines timing parameters supported by the display screen according to the first resolution, wherein the timing parameters are used to control the display screen to display an image, and the timing parameters include at least a second resolution determined by the first resolution that is consistent with the storage of the control device.

[0052] It should be explained that the range of resolution sizes that the control device can support is limited. For example, after the control device obtains the first resolution configured for the display screen controlled by the control device from the input device, it is also necessary to determine whether the first resolution is within the range of resolution sizes that the control device can support. In other words, if the first resolution is not supported, the control device cannot control the image data configured with the first resolution to be displayed on the display screen.

[0053] As an example, the maximum resolution supported by the control device is 1920×1080, and the first resolution is 1280×720. If the size of the first resolution is within the resolution range of the display screen supported by the control device, then the control device can support the first resolution.

[0054] It should be noted that, regarding the situation where the control device cannot support the first resolution, reference may be made to the following embodiments, which will not be described in detail here.

[0055] It should be explained that the timing parameters are used to display the pixel data in the image on the display screen in sequence within a preset time, so as to achieve the effect of controlling the display screen to display the image according to the timing parameters. Specifically, the timing parameters at least include a second resolution determined by the first resolution that conforms to the storage of the control device, and the second resolution and the first resolution may be the same in size or different in size. Exemplarily, when the first resolution conforms to the resolution stored in the control device, the first resolution and the second resolution are the same in size. When the first resolution does not conform to the resolution stored in the control device, the first resolution needs to be processed to obtain the second resolution that conforms to the storage of the control device.

[0056] It should be explained that the timing parameters also include resolution parameters determined by the second resolution, wherein the resolution parameters include horizontal blanking and vertical blanking.

[0057] Among them, horizontal blanking interval (HBI) is to eliminate the retrace process of the electron beam when it is scanning horizontally, and vertical blanking interval (VBI) is to eliminate the retrace process of the electron beam when it is scanning vertically.

[0058] It should be understood that an image is composed of frames, and each frame is composed of multiple pixels. The control device controls the electron gun to output pixels sequentially on the display screen in a fixed direction, thereby forming a complete frame of the image. Exemplarily, the control device controls the electron gun to output pixels from left to right on the display screen, because the electron gun draws a scan line each time, where the scan line is composed of multiple pixels. The electron gun returns to the left before drawing the next one and prepares for the next scan line. There is a period of time called horizontal blanking. Exemplarily, the control device controls the electron gun to output multiple rows of scan lines in order from top to bottom until a complete frame of the picture is output. After outputting a frame of the picture, the electron gun controlled by the control device needs to return to the upper left corner of the display screen when outputting the next frame of the picture. The period of time in between is called vertical blanking.

[0059] Regarding how to determine the resolution parameter according to the second resolution, reference may be made to the following embodiments, which will not be described in detail here.

[0060] Step 430: The control device configures timing parameters for the display screen.

[0061] An embodiment of the present application provides a method for adjusting the resolution of an LED display screen. The control device obtains a first resolution configured for the display screen controlled by the control device from the input device through a communication connection between the control device and the input device. In this way, the resolution configured for the display screen by the user through the input device can be determined. The control device also needs to determine that the control device can support the first resolution to ensure that the first resolution is within the processing capability of the control device. When the control device determines that the control device can support the first resolution, the control device determines the timing parameters supported by the display screen and configures the timing parameters to the display screen. In this way, the technical effect of the control device automatically adjusting the resolution size of the LED display screen according to the resolution information configured by the user can be achieved.

[0062] In a possible embodiment of the present application, the timing parameters further include: horizontal blanking and vertical blanking, and the vertical blanking is a preset value.

[0063] In a possible embodiment of the present application, the method provided in the embodiment of the present application can be implemented in the above step 420 in the following manner:

[0064] Step 421: The control device determines a second resolution according to the first resolution.

[0065] In a possible embodiment of the present application, the first resolution includes a first vertical resolution and a first horizontal resolution, and correspondingly, the second resolution includes a second vertical resolution and a second horizontal resolution.

[0066] It should be explained that the first vertical resolution and the first horizontal resolution can be respectively expressed as the resolution size in the vertical direction and the resolution size in the horizontal direction in the image applying the first horizontal resolution. Correspondingly, the second vertical resolution and the second horizontal resolution can be respectively expressed as the resolution size in the vertical direction and the resolution size in the horizontal direction in the image applying the second horizontal resolution. Taking the first resolution of 1920×1080 as an example, illustratively, the first horizontal resolution of the first resolution is 1920, and the first vertical resolution of the first resolution is 1080.

[0067] In a possible embodiment of the present application, the manner in which the control device determines the second resolution according to the first resolution may include the following situations:

[0068] Case 1: When the first vertical resolution can divide the first value evenly, the control device uses the first vertical resolution as the vertical resolution in the second resolution.

[0069] Case 2: When the first horizontal resolution can divide the first value evenly, the control device uses the first horizontal resolution as the horizontal resolution in the second resolution.

[0070] Case 3: When the first horizontal resolution is not an integer multiple of the first value, the control device uses the second horizontal resolution as the horizontal resolution in the second resolution, and the second horizontal resolution is the minimum value among the values ​​that are greater than the first horizontal resolution and are integer multiples of the first value.

[0071] Case 4: When the first vertical resolution is not an integer multiple of the first value, the control device uses the second vertical resolution as the vertical resolution in the second resolution, and the second vertical resolution is the minimum value among the values ​​that are greater than the first vertical resolution and are integer multiples of the first value.

[0072] The first value is a unit value used by the control device to store data. For example, when the unit value used by the control device to store data is 8, the size of the data stored in the control device is an integer multiple of 8. Therefore, when the first horizontal resolution and / or the first vertical resolution included in the first resolution is not an integer multiple of the first value, the first horizontal resolution and / or the first vertical resolution need to be processed to obtain a second horizontal resolution obtained by processing the first horizontal resolution, and / or a second vertical resolution obtained by processing the first vertical resolution.

[0073] It should be explained that the size of the first numerical value can be determined according to the byte corresponding to the number of bits of the control device. Taking a 64-bit computer as an example, the data read in a 64-bit computer is up to 64 bits wide, that is, 8 bytes wide. Therefore, the first numerical value in a 64-bit computer is 8. Since the control device accesses data in bytes corresponding to the number of bits, that is, the data in the control device needs to be byte-aligned, for example, in a 64-bit computer, it is necessary to access data in units of 8 bytes to achieve fast data access and effectively save storage space. Therefore, the data in the control device (such as the size of the resolution) is an integer multiple of the first numerical value. Therefore, before determining the timing parameters supported by the display screen, the control device also needs to determine a second resolution that is an integer multiple of the first numerical value based on the first resolution, and determine the timing parameters supported by the display screen for the display screen through the second resolution.

[0074] This embodiment is described below using the first value of 8 as an example.

[0075] As an example, if the first resolution is 1920×1080, the first horizontal resolution is 1920, and the first vertical resolution is 1080. When both the first horizontal resolution 1920 and the first vertical resolution 1080 can divide the first value 8, the first horizontal resolution 1920 is used as the second horizontal resolution, and the first vertical resolution 1080 is used as the vertical resolution in the second resolution. Therefore, the second resolution is determined to be 1920×1080.

[0076] As another example, if the first resolution is 1920×1070, the first horizontal resolution is 1920, and the first vertical resolution is 1070. If the first horizontal resolution 1920 can divide the first value 8, but the first vertical resolution cannot divide the first value 8, the first horizontal resolution 1920 is used as the second horizontal resolution, and the second vertical resolution is the minimum value 1072 that is greater than the first vertical resolution 1070 and is an integer multiple of the first value 8. Therefore, the second resolution is determined to be 1920×1072.

[0077] As another example, if the first resolution is 1900×1080, the first horizontal resolution is 1900, and the first vertical resolution is 1080. In the case where the first horizontal resolution 1900 cannot divide the first value 8, and the first vertical resolution can divide the first value 8, the first horizontal resolution 1900 is the minimum value 1904 that is greater than the first horizontal resolution 1900 and is an integer multiple of the first value 8, and the first vertical resolution 1080 is used as the vertical resolution in the second resolution. Therefore, the second resolution is determined to be 1904×1080.

[0078] As another example, if the first resolution is 1900×1070, the first horizontal resolution is 1900, and the first vertical resolution is 1070. In the case that neither the first horizontal resolution 1900 nor the second vertical resolution 1070 can divide the first value 8, the first horizontal resolution 1900 is the minimum value 1904 that is greater than the first horizontal resolution 1900 and is an integer multiple of the first value 8, and the second vertical resolution is the minimum value 1072 that is greater than the first vertical resolution 1070 and is an integer multiple of the first value 8. Therefore, the second resolution is determined to be 1904×1072.

[0079] Step 422: The control device obtains a clock frequency and a display frame rate, wherein the clock frequency and the display frame rate are used to control the device to control the display screen to display an image.

[0080] Specifically, the clock rate is a basic frequency that enables the display screen to display images synchronously and stably when the control device controls the display screen. The clock rate is determined by the performance of the control device. The clock rate can be preset to 148.5MHz (148.5*10 6 Hz). Of course, it can also be preset to other values ​​according to the performance of the control device, and this embodiment of the present application does not limit this.

[0081] Specifically, the display frame rate (Frame Rate) is the frequency at which a phase image in frames appears continuously on the display, and is a measure for measuring the number of display frames. For example, when a control device controls a display screen, the higher the display frame rate, the smoother the image displayed on the display screen will be. The measurement unit of the display frame rate is "frames per second (Frame per Second, FPS)", and FPS is used to describe how many frames a video, electronic drawing, or game plays per second. Normally, the display frame rate can be preset to 60FPS, that is, the image displayed on the display screen is updated evenly 60 times per second. Of course, the display frame rate can also be preset to other values, which is not limited in the embodiments of the present application.

[0082] This embodiment is described below by taking a clock frequency of 148.5 MHz and a display frame rate of 60 FPS as an example.

[0083] Step 423: The control device determines vertical blanking according to horizontal blanking, clock frequency, preset frame rate, and second resolution.

[0084] The second resolution includes a second horizontal resolution and a second vertical resolution.

[0085] The horizontal blanking in the embodiment of the present application is a preset value. The following description of the embodiment is based on the horizontal blanking of 160.

[0086] As an example, the method for the control device to determine the vertical blanking according to the horizontal blanking, the clock frequency, the display frame rate, and the second resolution may refer to the following formula:

[0087] Clock frequency = (second horizontal resolution + horizontal blanking) * (second vertical resolution

[0088] + vertical blanking)*display frame rate

[0089] For example, set the horizontal blanking to 160 and the clock frequency to 148.5*10 6 Hz, the display frame rate is 60FPS, the second horizontal resolution is 1960, and the second vertical resolution is 1080. Substitute them into the above formula, and the value calculated by vertical blanking is 87.453.

[0090] In a possible embodiment of the present application, the method provided in the embodiment of the present application further includes the following steps after the above step 430:

[0091] Step 440: When the control device determines that the timing parameters are incompatible with the display screen, the control device uses the first algorithm to redetermine the first timing parameters for the display screen according to the second resolution.

[0092] Among them, the first timing parameter is used to control the display screen to display an image and the first timing parameter is different from the timing parameter in value. It should be explained that when the timing parameter is incompatible with the display screen, the timing parameter cannot be used to control the display screen to display an image, so it is necessary to adopt the first algorithm to redetermine the first timing parameter for controlling the display screen to display an image. Since the algorithms used to determine the first timing parameter and the timing parameter are different, the first timing parameter and the timing parameter are different in value. Correspondingly, when the determined timing parameter is incompatible with the display screen, the horizontal blanking and vertical blanking in the timing parameter are incompatible with the display screen. Therefore, according to the first algorithm, the horizontal blanking and vertical blanking for controlling the display screen to display an image are redetermined. Therefore, the horizontal blanking and vertical blanking in the timing parameter and the horizontal blanking and vertical blanking in the first timing parameter are also different in value.

[0093] In a possible implementation, after the control device configures the timing parameters to the display screen, the control device determines whether the timing parameters are compatible with the display screen according to the situation of the image displayed on the display screen, such as whether the display screen can display the image normally. Exemplarily, when the screen body flickers on the display screen, the control device determines that the timing parameters are incompatible with the display screen, and therefore the control device cannot control the display screen to display the image through the timing parameters.

[0094] Exemplarily, the first algorithm may be an algorithm for calculating the first timing parameters, such as Coordinated Video Timings (CVT). Of course, the first algorithm may also be another algorithm that can calculate the first timing parameters, such as the GTF (Generalized Timing Formula) algorithm. The embodiment of the present application does not limit the algorithm for calculating the first timing parameters. It should be explained that the CVT algorithm is a standard method for calculating the first timing parameters. The GTF algorithm is a method for generating industrial standard timing. A set of general standard first timing parameters can be generated by the CVT algorithm or the GTF algorithm. It should be noted that the first timing parameters are considered to be standard timing parameters and have good compatibility on the display screen, so the display screen can be controlled to display images through the first timing parameters.

[0095] Step 450: The control device configures the first timing parameter to the display screen.

[0096] In a possible embodiment of the present application, the method provided in the embodiment of the present application further includes the following implementation: when the control device cannot support the first resolution, the control device outputs the first prompt information to the input device. Accordingly, the input device receives the first prompt information from the control device.

[0097] The first prompt information is used to prompt the control device that the control device does not support the first resolution. Optionally, the first prompt information may carry indication information, and the indication information is used to prompt the input device that the control device does not support the first resolution.

[0098] In a possible implementation manner, the control device outputs first prompt information to the input device when the control device cannot achieve the first horizontal resolution and / or the first vertical resolution.

[0099] As an example, the resolution range of the display screen supported by the control device is within 1920×1080, and the first resolution is 1920×1440. The size of the horizontal resolution in the first resolution is within the range of the horizontal resolution of the display screen supported by the control device, and the size of the first vertical resolution is not within the range of the resolution of the display screen supported by the control device, then the control device does not support the first resolution. Therefore, the control device cannot control the image data configured with the first resolution to be displayed on the display screen.

[0100] In a possible implementation, after acquiring the first prompt information from the control device, the input device prompts the user that the control device does not support the first resolution, and / or guides the user to reconfigure the first resolution.

[0101] Exemplarily, the input device may prompt the user on a display screen of the input device that the control device does not support the first resolution, and / or guide the user to reconfigure the first resolution. The input device may also prompt the user through a voice output device (audio device) that the control device does not support the first resolution, and / or guide the user to reconfigure the first resolution.

[0102] In a possible embodiment of the present application, the number of pixels corresponding to the first resolution is within the range of the number of pixels that can be carried by the control device.

[0103] It should be explained that the correspondence between the first resolution and the number of pixels can be referred to as shown in the following example. For example, taking the first resolution of 1920×1080 as an example, the number of pixels corresponding to the first resolution is 2,073,600.

[0104] It needs to be explained that the range of the number of pixels that the control device can carry refers to the range of the control device's ability to support images containing a specific number of pixel points. The range of the number of pixels that the control device can carry is limited. The maximum load capacity of the control device is determined by the performance of the control device, and the maximum load can be 650,000 pixels or 2.3 million pixels. Exemplarily, the control device can carry a maximum of 2.3 million pixels. Taking the first resolution of 1920×1080 as an example, the number of pixels corresponding to the first resolution is 2,073,600. Then the number of pixels corresponding to the first resolution is within the range of the number of pixels that the control device can carry.

[0105] In a possible implementation of the present application, the method provided in the embodiment of the present application further includes the following implementation before the above step 410: the input device determines that the number of pixels corresponding to the first resolution is within the range of the number of pixels that the control device can carry in response to the user configuring the first resolution configured for the display screen controlled by the control device on the input device. The input device sends the first resolution configured for the display screen controlled by the control device to the control device.

[0106] As an example, the first resolution configured by the user on the input device is 1920×1080, the number of pixels corresponding to the first resolution is 2,073,600, and the control device can carry a maximum of 2.3 million pixels. Then the input device determines that the number of pixels corresponding to the first resolution is within the range of pixels that the control device can carry.

[0107] In a possible implementation of the present application, the method provided in the embodiment of the present application may further include the following implementation before the above step 410: the input device determines that the number of pixels corresponding to the first resolution is outside the range of the number of pixels that the control device can carry in response to the user configuring the first resolution displayed on the display screen controlled by the control device on the input device. The input device outputs a second prompt message.

[0108] The second prompt information is used to prompt the user that the number of pixels corresponding to the first resolution is outside the range of the number of pixels that the control device can carry, and / or to guide the user to reconfigure the first pixel on the input device. Optionally, the input device can output the second prompt information on the display screen of the input device, or can output the second prompt information through a voice output device (audio device).

[0109] As a possible implementation method, the first resolution corresponds to a first pixel configured for the display screen, and the first pixel is within the pixel range that the control device can carry. The method provided in the embodiment of the present application also includes the following method: the input device obtains the first resolution corresponding to the first pixel in response to the user configuring the first pixel configured for the display screen controlled by the control device on the input device. The input device sends the first resolution to the control device.

[0110] The first pixel is the number of set pixels.

[0111] As an example, the input device may also support the user to set a first pixel on the input device. The input device obtains a first resolution corresponding to the first pixel based on the first pixel. Exemplarily, the first pixel is 2073600 pixels, and the input device obtains a first resolution of, for example, 1920×1080 based on the first pixel. It should be noted that the first horizontal resolution and the first vertical resolution included in the first resolution are within the range of the horizontal resolution and the vertical resolution that the control device can support.

[0112] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the interaction between various network elements.
