[0031] Embodiment 1

[0032] Figure 2 The following is a flowchart of a method for displaying a screen provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the resolution of the screen to be displayed is adaptively adjusted based on the resolution of the light-emitting diode display screen to ensure the screen display effect. This method can be executed by a screen display device, which can be implemented in the form of hardware and / or software, and the screen display device can be configured in a computer. As Figure 2 shown, the method includes:

[0033] S110. Determine the screen data source and determine the first resolution corresponding to the screen data source, and determine the second resolution of the light-emitting diode display screen for which the screen is to be displayed.

[0034] Among them, the screen data source can be understood as a data source related to the screen. Specifically, the screen data source can be uploaded through a target terminal. The target terminal can be a computer or a mobile phone connected to the LED screen, etc.

[0035] The first resolution can be understood as the resolution of the source screen corresponding to the screen data source. In the embodiment of the present invention, the first resolution is related to the screen data source received in the actual scene, and no specific limitation is made here. Usually, common first resolutions include 1920x1080, 3840x2160, or 1366x768, etc.

[0036] The light-emitting diode display screen can be used to display screen data. The second resolution can be understood as the resolution of the light-emitting diode display screen. The light-emitting diode display screen is also the above-mentioned LED screen. Exemplarily, LED screens are usually built at the scene of shopping malls, concerts or fashion shows. The resolution of LED screens on the market is usually not fixed. That is, the second resolution in the embodiment of the present invention is related to the model of the LED screen in the actual scene. In summary, no specific limitation is made to the second resolution here. Exemplarily, the second resolution can be 1920x1080, 3840x2160, or 1366x768, etc. The second resolution in the embodiment of the present invention is input through the user's resolution input operation.

[0037] S120. Compare the first resolution and the second resolution to obtain a comparison result, and process the screen data source according to the comparison result to obtain the first screen data with the target resolution.

[0038] The comparison result in the embodiments of the present invention can characterize the magnitude relationship between the first resolution and the second resolution. Optionally, the comparison result can at least include a first result indicating that the first resolution does not exceed the second resolution and a second result indicating that the first resolution exceeds the second resolution.

[0039] The target resolution can be understood as a preset fixed resolution. Specifically, when the comparison result is the first result, the picture data source is reduced or enlarged to the picture data of the fixed resolution corresponding to the first result; when the comparison result is the second result, the picture data source is reduced or enlarged to the picture data of the fixed resolution corresponding to the second result. In the embodiments of the present invention, the fixed resolution corresponding to the first result and the fixed resolution corresponding to the second result can be different. That is, the third resolution and the second resolution in the embodiments of the present invention can be different.

[0040] In addition, the fixed resolution corresponding to the first result and the fixed resolution corresponding to the second result can also be the same.

[0041] The first picture data can be understood as the picture data corresponding to the target resolution.

[0042] S130. Determine picture processing parameters according to the comparison result, and process the first picture data of the target resolution according to the picture processing parameters to obtain second picture data.

[0043] Among them, the picture processing parameters can be understood as parameters for optimizing the picture display effect. In the embodiments of the present invention, the picture optimization parameters can be preset according to the scene requirements, and no specific limitation is made here. Optionally, the picture processing parameters can include parameters such as clarity, sharpness, and color contrast. In the embodiments of the present invention, the picture processing parameters corresponding to different comparison results can be different. The picture processing parameters can include a first processing parameter corresponding to the first result and a second processing parameter corresponding to the second result. The first processing parameter and the second processing parameter can be different.

[0044] It should be noted that, whether the first resolution does not exceed the second resolution or the first resolution exceeds the second resolution in the present invention, the picture data source will be scaled to the first picture data with a fixed resolution. Therefore, there can only be two fixed ratios between the resolution of the obtained first picture data and the resolution of the LED screen at this time. The embodiments of the present invention only need to preset two sets of picture processing parameters that match the two possible fixed ratios to achieve the optimization of the picture display in any application scenario (the resolution of the LED screen and the resolution of the source picture can be different in different application scenarios), and ensure the high-quality display effect of the picture data on the LED screen. On the basis of ensuring the picture display effect, the present invention improves the simplicity of the picture display effect optimization process.

[0045] Further, specifically, the display effect of the first picture data with the target resolution is optimized according to the picture processing parameters to obtain the second picture data.

[0046] Optionally, the comparison result includes a second result indicating that the first resolution exceeds the second resolution; the target resolution includes the second resolution; and the process of processing the picture data source according to the comparison result to obtain the first picture data with the target resolution includes:

[0047] When the comparison result is the second result, the picture data source with the first resolution is reduced to the first picture data with the second resolution.

[0048] Specifically, when the first resolution corresponding to the picture data source exceeds the second resolution of the LED screen, the resolution of the picture data source with the first resolution is reduced to the second resolution.

[0049] Optionally, the picture processing parameters include second processing parameters; and the process of determining the picture processing parameters according to the comparison result includes:

[0050] Determine the second processing parameter corresponding to the second result according to the target database.

[0051] The second processing parameter in the embodiments of the present invention can be understood as a screen optimization parameter corresponding to the second result. To sum up, when the comparison result is the second result, the resolution ratio between the first screen data and the LED screen is 1. Therefore, the second processing parameter can be a processing parameter that can maintain the display effect of the first screen data. Generally speaking, when the comparison result is the second result, the display effect of the first screen data is not optimized accordingly. The second processing parameter can be a set of parameter sets. This parameter set can include parameters such as clarity, sharpness, and color contrast. Specifically, in the embodiments of the present invention, the specific method for optimizing the display effect of the first screen data with the target resolution based on the second processing parameter can be set according to the actual scenario requirements. No specific limitation is made here.

[0052] The target database in the embodiments of the present invention can be used to store the screen processing parameters corresponding to different comparison results. Optionally, the target database may store the first processing parameter corresponding to the first result and the second processing parameter corresponding to the second result.

[0053] Based on the above embodiment solutions, it is possible to ensure the restoration degree of the LED screen display image when the resolution of the source screen exceeds the resolution of the LED screen.

[0054] Exemplarily, an optional embodiment of the following screen display method is described:

[0055] The first resolution of the screen data source is 1920x1080, and the second resolution of the LED screen is 960x540. Specifically, the first resolution exceeds the second resolution, the comparison result is the second result, the 1920x1080 screen data source is reduced to the first screen data of 960x540, the first screen data is processed according to the second processing parameter, and the second screen data consistent with the display effect of the first screen data is obtained. Further, the second screen data is sent to the LED, and the second screen data in a fixed format is sent to the LED screen through the LED, and the second screen data is displayed through the LED screen.

[0056] The present invention scales the screen data source to the first screen data with a resolution that forms a target ratio with the screen resolution according to the comparison result between the resolution of the screen and the resolution of the LED screen, so as to further optimize the display effect of the first screen data based on the screen processing parameter corresponding to the target ratio, that is, there is no need to set corresponding screen processing parameters for any possible resolution ratio between the source screen and the LED screen. On the basis of ensuring the simplicity of the screen display effect optimization process, the display effect of the LED screen is improved when the resolution of the source screen is different from the resolution of the LED screen.

[0057] S140. Display the second screen data through the light-emitting diode display screen.

[0058] In the technical solution of the embodiment of the present invention, by determining the screen data source and determining the first resolution corresponding to the screen data source, the second resolution of the light-emitting diode display screen to be used for screen display is determined; the first resolution and the second resolution are compared to obtain a comparison result, and the screen data source is processed according to the comparison result to obtain the first screen data with the target resolution; according to the comparison result, screen processing parameters are determined, and the first screen data with the target resolution is processed according to the screen processing parameters to obtain the second screen data; the second screen data is displayed through the light-emitting diode display screen. According to the comparison result between the resolution of the screen and the resolution of the LED screen in the present invention, targeted resolution scaling is performed on the source screen, and by using the screen processing parameters corresponding to the comparison result, it is possible to optimize the display effect with high matching for the first screen data after resolution scaling. There is no need to set corresponding screen optimization parameters for any possible resolution of the source screen and the resolution of the LED screen. On the basis of ensuring the simplicity of the screen display effect optimization process, the screen display effect of the LED screen is improved when the resolution of the source screen is different from the resolution of the LED screen.

[0059] Embodiment 2

[0060] Figure 3 It is a flowchart of a screen display method provided by Embodiment 2 of the present invention. This embodiment details the process of processing the screen data source according to the comparison result to obtain the first screen data with the target resolution in the above embodiment. As Figure 3 shown, the method includes:

[0061] S210. Determine the screen data source and determine the first resolution corresponding to the screen data source, and determine the second resolution of the light-emitting diode display screen to be used for screen display.

[0062] S220. Compare the first resolution and the second resolution to obtain a comparison result.

[0063] Optionally, the target resolution may include the third resolution and the second resolution. In the embodiment of the present invention, the third resolution may not exceed the second resolution.

[0064] S230. In the case where the comparison result is the first result, determine the preset third resolution, and enlarge the screen data source with the first resolution to the first screen data with the third resolution.

[0065] Specifically, when the first resolution corresponding to the picture data source does not exceed the second resolution of the LED screen, the resolution of the picture data source with the first resolution is enlarged to the third resolution.

[0066] The third resolution in the embodiments of the present invention can be understood as a preset fixed resolution. Optionally, the third resolution can be determined according to the second resolution and a preset target ratio. In the embodiments of the present invention, the specific parameters of the third resolution are related to the actual application scenario and are not specifically limited herein. Specifically, before determining the preset third resolution, the following steps are further included:

[0067] In response to a resolution setting operation, determine the third resolution, where the third resolution is determined according to the second resolution and a preset target ratio.

[0068] Among them, the target ratio can be understood as a resolution ratio that facilitates optimizing the picture display effect. The target ratio can be an integer scaling ratio.

[0069] For example, historical optimization data indicates that when the resolution is A, the optimization effect of the picture display is better, then the resolution A is set as the target ratio. The specific value of the target ratio can be related to the performance parameters of the data processing device and is not specifically limited herein. The target ratios corresponding to different data processing devices can be different. Specifically, the target ratio can be a fixed parameter set based on the performance parameters of the data processing device. Among them, the data processing device can be understood as a device related to picture processing. Optionally, the data processing device can include a DSP or an FPGA, etc. The performance parameters can be understood as parameters related to the performance of the data processing device. It can be understood that the performance parameters corresponding to different data processing devices are usually different. In the embodiments of the present invention, the performance parameters can be preset according to the scenario requirements and are not specifically limited herein.

[0070] The resolution setting operation can be understood as an operation for setting the third resolution. The resolution setting operation in the embodiments of the present invention can be performed by a staff member. In the embodiments of the present invention, the specific execution manner of the resolution setting operation is not specifically limited. Optionally, the resolution setting operation can be a selection operation for options of multiple candidate resolutions, or an input operation for the resolution in an input box, etc. In addition, optionally, the third resolution can also be directly generated based on the second resolution input by the user and the target ratio input by the user. The execution manner of the user inputting the second resolution and the target ratio can be the same as the above resolution setting operation and is not specifically limited herein.

[0071] Optionally, the screen processing parameter includes a first processing parameter; determining the screen processing parameter according to the comparison result includes:

[0072] Determine the first processing parameter corresponding to the first result according to the target database, where the first processing parameter is a processing parameter corresponding to the target ratio.

[0073] Among them, the first processing parameter can be understood as a screen optimization parameter corresponding to the first result, or can be understood as a screen optimization parameter matching the target ratio. The first processing parameter can be a set of parameters different from the second processing parameter. This parameter set can include parameters such as clarity, sharpness, and color contrast. Specifically, in the embodiments of the present invention, the specific method for optimizing the display effect of the first screen data with the target resolution based on the first processing parameter can be set according to actual scenario requirements. No specific limitation is made here.

[0074] The first processing parameter in the embodiments of the present invention can be set specifically based on a fixed target ratio between the second resolution and the third resolution. The set first processing parameter can achieve better screen display optimization for the screen data of the third resolution that is in a fixed target ratio with the second resolution. The first processing parameter in the embodiments of the present invention can match the target ratio. The target ratios in different actual scenarios can be the same.

[0075] The present invention can convert the source screen of any resolution into the first screen data that is in a target ratio with the LED screen, and the present invention presets a first processing parameter corresponding to the target ratio. This first processing parameter can perform high-quality display effect optimization on the screen data of the resolution that is in a target ratio with the second resolution of the LED screen. In summary, the present invention can achieve the technical effect of presetting a first processing parameter to achieve high-quality display effect optimization for the source screen of any resolution.

[0076] Based on the above embodiment solution, it is possible to ensure the stability of the display screen effect of the LED screen when the resolution of the source screen does not exceed the resolution of the LED screen.

[0077] S240. Determine the screen processing parameter according to the comparison result, and process the first screen data with the target resolution according to the screen processing parameter to obtain second screen data.

[0078] Exemplarily, another optional embodiment of the following screen display method is described:

[0079] The first resolution of the screen data source is 960x540, and the second resolution of the LED screen is 3840x2160. Specifically, since the first resolution does not exceed the second resolution, the comparison result is the first result. The screen data source with a resolution of 960x540 is enlarged to the first screen data with a third resolution of 1920x1080, and the display effect of the first screen data with a resolution of 1920x1080 is optimized according to the first processing parameter, resulting in the second screen data. The first processing parameter is specifically set according to the target ratio. Further, the second screen data is sent to the LED, and the LED sends the second screen data in a fixed format to the LED screen, and the second screen data is displayed through the LED screen.

[0080] S250. Display the second screen data through the light-emitting diode display screen.

[0081] In the technical solution of the embodiment of the present invention, when the comparison result is the first result, the preset third resolution is determined, and the screen data source with the first resolution is enlarged to the first screen data with the third resolution. The present invention enlarges the screen data source with a resolution smaller than that of the LED screen to the first screen data with a third resolution that is in a target ratio with the screen resolution, which is convenient for later optimizing the display effect of the first screen data uniformly and with high adaptability through the screen optimization parameters corresponding to the target ratio.
