[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The different EDID types of existing display devices are mainly reflected in the display of HDMI signals with different display types, and different types of HDMI signals need to use matching EDID types to fully display the corresponding picture content of the HDMI signal. That is, after the display device is connected to the source device, it is usually necessary to switch the EDID type of the display device to an EDID type that matches the HDMI signal output by the source device, so that the picture corresponding to the HDMI signal output by the source device can be normally displayed through the display device. If the HDMI signal does not match the EDID type, the picture will not be clear enough or the display will be abnormal. The existing EDID type switching is mainly manual switching by users. Since most users have little knowledge of EDID types, multiple repeated switching may occur during the specific switching to switch to the appropriate EDID type, that is, there are problems of high switching difficulty and poor user experience.

[0052] In order to solve the problems of high switching difficulty and poor user experience in the existing related technologies that require manual operation to switch between different display types of display devices, the present application provides a display device control method, device, electronic device and storage medium, by obtaining high-definition multimedia interface information of the display device, determining the source device information corresponding to the high-definition multimedia interface information, and when the source device information does not belong to the preset whitelist information, determining the encryption protocol version information of the high-definition multimedia interface information, and comparing the encryption protocol version information with the preset version information to obtain version comparison information, and then based on the version comparison information, combining with the preset initial display type of the display device, switching the display type is performed to obtain the display type switching result of the display device; thereby, the display type of the display device can be adaptively switched according to the high-definition multimedia interface information without the need for manual switching by the user, thereby solving the problems of high switching difficulty and poor user experience in the existing related technologies that require manual operation to switch between different display types of the display device, and can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

The method can be applied to one or more electronic devices such as a display device, a client, and a server. In addition, the execution subject of the method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute the method, or a plurality of electronic devices can cooperate with each other to execute the method. When the above-mentioned execution subject is software, the method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0054] like Figure 1 As shown, the present application discloses an embodiment, providing a display device control method, which may specifically include the following steps:

[0055] Step S110: obtaining high-definition multimedia interface information of the display device;

[0056] Among them, the high-definition multimedia interface information may refer to the HDMI information received by the display device through the HDMI cable. The specific method of obtaining it may be to monitor the HDMI status through the HDMI driver (HDMIDriver), wherein the HDMIDriver may be a set of software codes for controlling and managing the HDMI hardware interface in the system, responsible for processing functions such as data transmission, signal conversion, device detection, resolution and refresh rate setting, etc. Of course, other methods may also be used to obtain the high-definition multimedia interface information of the display device, and this embodiment does not make any specific limitations on this.

[0057] Step S120: Determine source device information corresponding to the high-definition multimedia interface information.

[0058] Specifically, after obtaining the high-definition multimedia interface information, the source device information corresponding to the high-definition multimedia interface information can be determined. The source device information can refer to the information of the source device corresponding to the high-definition multimedia interface information. That is, the source device information can be used to indicate the source device that sends the high-definition multimedia interface information, such as the identification, model, name, etc. corresponding to the source device.

[0059] Step S130: when the source device information does not belong to the preset whitelist information, determine the encryption protocol version information of the high-definition multimedia interface information.

[0060] Specifically, after determining the source device information, it can be determined whether the source device information belongs to the preset whitelist information. The preset whitelist information may be source device information of a known required display type. That is, when the source device information belongs to the whitelist information, the display type corresponding to the source device information may be directly determined based on the whitelist information. When the source device information does not belong to the preset whitelist information, the encryption protocol version information of the high-definition multimedia interface information may be determined. The encryption protocol version information is the version of the encryption protocol adopted by the high-definition multimedia interface information, and specifically may be a version corresponding to the High-bandwidth Digital Content Protection (HDCP) protocol.

[0061] In one example, the whitelist information may include source device information of known required display types, for example, the whitelist information may include PS4 (PlayStation 4), XBOX gaming console, and Digital Versatile Disc (DVD). Since the above source devices are relatively standard devices, their corresponding display types can be predetermined at this time, for example, PS4 and XBOX gaming console correspond to display type A, and DVD corresponds to display type B. When it is determined that the source device information is whitelist information, the display type corresponding to the source device information can be determined based on the aforementioned correspondence. When the source device information does not belong to the whitelist information, the display type corresponding to the source device information cannot be directly determined. At this time, the encryption protocol version information of the high-definition multimedia interface information can be determined.

[0062] Step S140: Compare the encryption protocol version information with the preset version information to obtain version comparison information.

[0063] Specifically, after determining the encryption protocol version information, the encryption protocol version information can be compared with the preset version information to obtain version comparison information, where the preset version information can represent a pre-configured version range, such as version 2.X or a version greater than 2.0, etc., and the version comparison information can be a comparison result that indicates whether the encryption protocol version information belongs to the preset version information.

[0064] Step S150: Based on the version comparison information, the display type is switched in combination with the initial display type preset by the display device to obtain a display type switching result of the display device.

[0065] Specifically, after obtaining the version comparison information, the display type can be switched according to the version comparison information and the initial display type preset by the display device to obtain the display type switching result of the display device, wherein the initial display type indicates the display type currently configured of the display device, that is, the EDID type of the current display device, and the specific display type switching needs to be judged in combination with the specific content of the version comparison information and the specific display type of the initial display type. At this time, the display type switching can be to switch the initial display type to other display types, or to maintain the current initial display type. This embodiment does not make specific limitations on this.

[0066] In one example, when switching the display type, a pre-configured switching comparison table may be obtained to determine the segmentation strategy, wherein the switching comparison table may include version comparison information and the initial display type, and the corresponding relationship with the switching strategy. For example, the version comparison information may be version comparison information A and version comparison information B, the initial display type may be display type X and display type Y, and the switching strategy may be maintaining the initial display type and switching to other display types. At this time, the switching comparison table may indicate that the switching strategy corresponding to the version comparison information A and the display type X is to maintain the initial display type, the switching strategy corresponding to the version comparison information A and the display type Y is to maintain the initial display type, the switching strategy corresponding to the version comparison information B and the display type X is to switch to other display types, and the switching strategy corresponding to the version comparison information B and the display type Y is to switch to other display types. In this way, the display type can be switched according to the pre-configured switching comparison table in combination with the version comparison information and the initial display type. Of course, the above is only an example for illustration. In specific implementation, adaptive adjustments can be made according to different scenarios and requirements, and this embodiment does not make specific limitations on this.

[0067] It can be seen that this embodiment obtains the high-definition multimedia interface information of the display device, determines the source device information corresponding to the high-definition multimedia interface information, and when the source device information does not belong to the preset whitelist information, determines the encryption protocol version information of the high-definition multimedia interface information, and compares the encryption protocol version information with the preset version information to obtain version comparison information, and then based on the version comparison information, combines the initial display type preset by the display device to switch the display type to obtain the display type switching result of the display device; thereby, the display type of the display device can be adaptively switched according to the high-definition multimedia interface information without the need for manual switching by the user, which solves the problems of high switching difficulty and poor user experience in the existing related technology that requires manual switching of different display types of the display device, and can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

[0068] In an optional embodiment of the present application, step S140 compares the encryption protocol version information with the preset version information to obtain version comparison information, which may specifically include the following sub-steps: extracting the target version number from the encryption protocol version information; determining the version number range corresponding to the preset version information; when the target version number is within the version number range, determining the version matching information as the version comparison information; when the version number is not within the version number range, determining the version mismatch information as the version comparison information.

[0069] In this embodiment, after the encryption protocol version information is determined, the target version number can be extracted from the encryption protocol version information. The target version number can be the version number of the encryption protocol adopted by the high-definition multimedia interface information. Then, the version number range corresponding to the preset version information can be determined. The version number range represents the range of the version number represented by the preset version information, such as the version number 2.X or the version number greater than 2.0, so that it can be judged whether the target version number is within the version number range. If the target version number is within the version number range, the version matching information is determined as the version comparison information. The version matching information can be information that the encryption protocol version information and the preset version information have a matching relationship. If the version number is not within the version number range, the version mismatch information is determined as the version comparison information. The version mismatch information can be information that the encryption protocol version information and the preset version information do not have a matching relationship. Therefore, it can be determined whether the encryption protocol version information and the preset version information have a matching relationship through the version comparison information, so that the display type can be switched based on the version comparison information in combination with the initial display type preset by the display device, and the display type switching result of the display device is obtained, that is, step S150 is executed.

[0070] In an optional embodiment of the present application, step S150 performs display type switching based on version comparison information in combination with an initial display type preset by the display device to obtain a display type switching result of the display device, which may specifically include the following sub-steps: when the version comparison information is version matching information, the preset first display type is compared with the initial display type to obtain a display type comparison result; when the display type comparison result is a display type matching result, the initial display type is maintained to obtain a display type switching result; when the display type comparison result is a display type mismatch result, the initial display type is switched to the first display type to obtain a display type switching result.

[0071] In this embodiment, after obtaining the version comparison information, it can be determined whether the version comparison information is version matching information, and when the version comparison information is version matching information, the preset first display type is compared with the initial display type to obtain a display type comparison result, wherein the first display type can represent a display type that matches the preset version information, and the display type comparison result can be a comparison result of whether the first display type is consistent with the initial display type, that is, the display type comparison result can be a display type matching result or a display type mismatching result, wherein the display type matching result can represent a result that the first display type is consistent with the initial display type, and the display type mismatching result can represent a result that the first display type is inconsistent with the initial display type; then, when the display type comparison result is a display type matching result, it indicates that the initial display type is consistent with the first display type, and the initial display type can be maintained to obtain a display type switching result, and when the display type comparison result is a display type mismatching result, it indicates that the initial display type is inconsistent with the first display type, and the initial display type can be switched to the first display type to obtain a display type switching result.

[0072] It should be noted that, in this embodiment, since the preset version information is a pre-configured version range, when the version comparison information is version matching information, it indicates that the version of the encryption protocol version information of the current high-definition multimedia interface information belongs to the pre-configured version range. At this time, the preset first display type can be compared with the initial display type to obtain the display type comparison result, and when the initial display type is consistent with the first display type, the initial display type is maintained, and when the initial display type is inconsistent with the first display type, the initial display type is switched to the first display type, thereby achieving the purpose of accurately switching the display type of the display device to the first display type that matches the preset version information. It can be seen that in this embodiment, the association between the high-definition multimedia interface information and the first display type is established through the encryption protocol version information, that is, the display type of the display device can be adaptively switched according to the high-definition multimedia interface information, without the need for manual switching by the user, which solves the problem of high switching difficulty and poor user experience in the existing related technology that requires manual switching of different display types of the display device, and can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

[0073] In addition, in this embodiment, multiple groups of preset version information and the first display type can also be pre-configured. For example, the encryption protocol version 2.X corresponds to the first group of preset version information A and the first display type A, and the encryption protocol version 3.X corresponds to the second group of preset version information B and the first display type B, etc. At this time, when executing step S140 to compare the encryption protocol version information with the preset version information to obtain version comparison information, the encryption protocol version information can be compared with each preset version information to obtain multiple version comparison information, so that it can be determined whether there is version comparison information that is version matching information in the multiple version comparison information. If so, the step of comparing the preset first display type with the initial display type to obtain the display type comparison result can be performed; thereby, it can be played to adapt the configuration of the applicable first display type for each encryption protocol version range, and the display type of the display device can be switched to the applicable first display type through the encryption protocol version information without the user manually selecting the configuration, which can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

[0074] In an optional embodiment of the present application, step S150 performs display type switching based on version comparison information in combination with an initial display type preset by the display device to obtain a display type switching result of the display device, which may specifically include the following sub-steps: when the version comparison information is version mismatch information, determining whether there is target data type information in the high-definition multimedia interface information; when there is target data type information in the high-definition multimedia interface information, performing display type switching based on a preset first display type in combination with the initial display type to obtain a display type switching result; when there is no target data type information in the high-definition multimedia interface information, performing display type switching based on a preset second display type in combination with the initial display type to obtain a display type switching result.

[0075] In this embodiment, after obtaining the version comparison information, it can be determined whether the version comparison information is version mismatch information, and when the version comparison information is version mismatch information, it is determined whether there is target data type information in the high-definition multimedia interface information, and the target data type information indicates pre-configured data type information that can be used to identify a specific type of high-definition multimedia interface information, such as high dynamic range (High-Dynamic Range, HDR) data type, HDR data type is usually only available in high-definition multimedia interface information with a higher display type standard; thus, when the target data type information exists in the high-definition multimedia interface information, it means that the high-definition multimedia interface information belongs to the high-definition multimedia interface information with a higher display type standard, then the display type can be switched according to the preset first display type and the initial display type to obtain the display type switching result, wherein the specific process of switching the display type according to the preset first display type and the initial display type to obtain the display type switching result can refer to the switching process in the aforementioned embodiment, which will not be repeated in this embodiment; when the target data type information does not exist in the high-definition multimedia interface information, it means that the high-definition multimedia interface information does not belong to the high-definition multimedia interface information with a higher display type standard, then the display type can be switched according to the preset second display type and the initial display type to obtain the display type switching result, wherein the second display type can be a display with a standard lower than the first display type, for example, when the first display type is EDID 2.14K, the second display type can be EDID 1.4 which is lower than the EDID 2.1 4K standard. 4K, and in addition, the display type is switched according to the preset second display type in combination with the initial display type. The specific process of obtaining the display type switching result can refer to the switching process in the aforementioned embodiment. The only difference between the two is that the first display type is replaced by the second display type. Therefore, the switching processes of the two are relatively similar and will not be repeated in this embodiment.

[0076] In an optional embodiment of the present application, step S130 determines the encryption protocol version information of the high-definition multimedia interface information when the source device information does not belong to the preset whitelist information. Specifically, it may include the following sub-steps: when the source device information does not belong to the whitelist information, obtaining the display data channel information of the display device; extracting the encryption protocol version information from the display data channel information.

[0077] In this embodiment, when the source device information does not belong to the whitelist information, the display data channel information of the display device can be obtained. The display data channel information represents information obtained from the display data channel (DDC). The DDC channel is an independent cable for transmitting data in the HDMI cable. Then, the encryption protocol version information can be extracted from the display data channel information.

[0078] It should be noted that in the HDMI cable connected to the display device, the encryption protocol version information HDCP is transmitted through the DDC channel. The HDMI cable consists of three sets of differential signals to transmit Transition Minimized Differential Signaling (TMDS) data, one set of differential signals to transmit the clock signal, and there is also a DDC channel connected to the EDID of the receiving device. The HDCP authentication process includes sending keys, receiving responses, calculating shared keys, verification and periodic re-authentication. This process is transmitted through the DDC channel, thereby ensuring that only authorized devices can receive and display protected content.

[0079] In an optional embodiment of the present application, after step S120 determines the source device information corresponding to the high-definition multimedia interface information, it may further include the following sub-steps: when the source device information belongs to the whitelist information, determine the target display type corresponding to the source device information based on the whitelist information; based on the target display type, switch the display type in combination with the initial display type to obtain a display type switching result.

[0080] In this embodiment, after determining the source device information corresponding to the high-definition multimedia interface information, if the source device information belongs to the whitelist information, the target display type corresponding to the source device information can be determined based on the whitelist information, and the target display type represents the display type that is compatible with the source device represented by the source device information; then, the display type can be switched based on the target display type and the initial display type to obtain a display type switching result. The specific switching process can be to compare the target display type with the initial display type to obtain a display type comparison result, wherein the target display type can represent a display type that matches the preset version information, and the display type comparison result can be a comparison of whether the target display type is consistent with the initial display type. The comparison result, that is, the display type comparison result can be a display type matching result or a display type mismatching result, wherein the display type matching result can indicate that the target display type is consistent with the initial display type, and the display type mismatching result can indicate that the target display type is inconsistent with the initial display type; then, when the display type comparison result is a display type matching result, it means that the initial display type is consistent with the target display type, and the initial display type can be maintained to obtain a display type switching result, and when the display type comparison result is a display type mismatching result, it means that the initial display type is inconsistent with the target display type, and the initial display type can be switched to the target display type to obtain a display type switching result.

[0081] It can be seen that in this embodiment, an association between the high-definition multimedia interface information and the target display type is established through the whitelist information, that is, the display type of the display device can be adaptively switched according to the high-definition multimedia interface information without the need for manual switching by the user. This solves the problem of high switching difficulty and poor user experience in the existing related technology that requires manual switching of different display types of the display device. It can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

[0082] In an optional embodiment of the present application, after step S110 obtains the high-definition multimedia interface information of the display device, it may further include the following sub-steps: determining the access information corresponding to the high-definition multimedia interface information; when the access information is the preset access information, determining whether the display type switching function of the display device is turned on; when the display type switching function is turned on, executing the step of determining the source device information corresponding to the high-definition multimedia interface information.

[0083] In this embodiment, after obtaining the high-definition multimedia interface information of the display device, the access information corresponding to the high-definition multimedia interface information can be determined. The access information can indicate whether the high-definition multimedia interface information is accessed for the first time. When the access information is preset access information, it is determined whether the display type switching function of the display device is turned on. The preset access information indicates that the high-definition multimedia interface information is pre-configured to indicate that the high-definition multimedia interface information is accessed for the first time. The display type switching function indicates the function of adaptively switching the display type of the aforementioned steps S120-150. When the display type switching function is turned on, the step of determining the source device information corresponding to the high-definition multimedia interface information and subsequent steps can be executed, that is, the display type of the display device can be adaptively switched according to the high-definition multimedia interface information without the need for manual switching by the user. This solves the problems of high switching difficulty and poor user experience in the existing related technology that requires manual switching of different display types of the display device, and can effectively reduce the difficulty of switching the display type of the display device and improve the user experience.

[0084] In one embodiment, the access information may be information generated in real time by the display device monitoring the HDMI interface. For example, the display device may continuously output a 5V monitoring signal for the HDMI interface. When the external source device is first connected, the display device may generate a 5V access signal, indicating that the external source device is connected. If the device has not been unplugged or interrupted in the middle, the 5V access signal is continuously maintained. If the device is unplugged and then connected again, the 0V signal will change to 5V again. That is, the preset access information may indicate that the access signal changes from 0V to 5V within a preset time period. Of course, the above is only an example for explanation. Other methods may also be used in specific implementations. This embodiment does not specifically limit this.
