[0029] The control module 220 may be a receiving card, a timing control (T-con) chip, a receiving card integrated with a field programmable gate array (FPGA) chip, or a receiving card integrated with a system on chip (Soc).

[0030] See also Figure 2 , which shows a flow chart of a display screen control method provided by an embodiment of the present application. In a specific embodiment, the display screen control method can be applied to Figure 1 The terminal device 100 in the display screen control system shown in FIG. 1 is taken as an example below. Figure 2 The process shown is described in detail, and the display screen control method may include the following steps S110 to S130.

[0031] Step S110: Obtaining historical operating parameters of the display screen.

[0032] In an embodiment of the present application, the historical operating parameters may be at least any one of the historical operating temperature of the control module of the display screen, the historical operating voltage of the control module, the historical operating current of the control module, the historical operating temperature of the light source module, the historical operating voltage of the light source module, or the historical operating current of the light source module.

[0033] When the terminal device receives the control instruction of the display screen, it responds to the received control instruction and can obtain the historical operating parameters of the display screen.

[0034] In some embodiments, the terminal device may include a local memory, and the control module may be used to collect historical operating parameters of the display screen and send the collected historical operating parameters to the terminal device via the network. The terminal device may be used to receive the historical operating parameters sent by the control module and store the received historical operating parameters in the local memory.

[0035] When the terminal device receives the control instruction of the display screen, it can read the pre-stored historical operating parameters from the local memory in response to the received control instruction.

[0036] In some embodiments, the display screen control system may further include a server, which may be connected to the terminal device and the control module via a network, and perform data exchange with the terminal device and the control module via the network.

[0037] The control module can be used to collect the historical operating parameters of the display screen and send the collected historical operating parameters to the server through the network. The server can be used to receive the historical operating parameters sent by the control module and store the received historical operating parameters in the network storage.

[0038] The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), big data, and artificial intelligence platforms. The type of server is not limited here and can be set according to actual needs.

[0039] When the terminal device receives a control instruction for the display screen, it can respond to the received control instruction by sending an acquisition instruction to the server via the network. The server receives and responds to the acquisition instruction, reads the historical operating parameters of the display screen stored in advance from the network memory, and sends the historical operating parameters to the terminal device via the network. The terminal device receives the historical operating parameters returned by the server via the network.

[0040] In some implementations, the terminal device may detect the user's operation, and when it is determined that the user has input an instruction to control the display screen based on the detected user's operation, the control instruction of the display screen is detected. For example, when the user needs to control the display screen, the user may perform a touch operation on the operation panel of the terminal device, and the terminal device responds to the user's touch operation, generates a corresponding touch signal, and analyzes the touch signal. When it is determined that the touch signal is a preset control signal, it is determined that the control instruction of the display screen is detected.

[0041] In some implementations, the terminal device may collect voice information input by the user, perform voice recognition on the voice information, and determine, based on the recognition result of the voice recognition, that the recognition result contains a keyword for indicating control of the display screen, such as "display screen display", and another example, "display screen" and "display", etc., and then determine that a control instruction for the display screen is detected. For example, if the voice information input by the user is: the display screen illuminates and displays, and the recognition result of the voice recognition contains the keyword "display screen" and the keyword "display", then it is determined that a control instruction for the display screen is detected.

[0042] Step S120: When it is determined that the display screen is abnormal based on the historical operating parameters, the target operating parameters are determined.

[0043] In the embodiment of the present application, the abnormality of the display screen may be a control module abnormality (for example, a receiving card abnormality), and / or a light source module abnormality, etc. After obtaining the historical operating parameters of the display screen, the terminal device may determine whether the display screen is abnormal according to the historical operating parameters, and when the display screen is determined to be abnormal according to the historical operating parameters, the target abnormality level of the display screen may be obtained, and the target operating parameters of the display screen may be determined according to the target abnormality level.

[0044] The target abnormality level can be used to characterize the deviation between the historical operating parameters of the display screen and the rated operating parameters of the display screen. The higher the target abnormality level, the greater the deviation between the historical operating parameters of the display screen and the rated operating parameters of the display screen; the lower the target abnormality level, the smaller the deviation between the historical operating parameters of the display screen and the rated operating parameters of the display screen.

[0045] The target operating parameter may be at least any one of a target display brightness, a target operating voltage or a target operating current, etc.; the target display brightness corresponding to the target operating parameter is lower than the historical display brightness corresponding to the historical operating parameter.

[0046] In some implementations, the terminal device can determine whether the display screen is abnormal based on historical operating parameters and set parameter thresholds. When the historical operating parameters are greater than or equal to the set parameter threshold, it is determined that the display screen is abnormal; when the historical operating parameters are less than the set parameter threshold, it is determined that the display screen is not abnormal.

[0047] The set parameter threshold may be used to characterize the working parameter value when the display screen does not have any abnormality. For example, the set parameter threshold may be the rated working parameter of the display screen.

[0048] As an example, the control module is a receiving card, the historical operating parameter is the historical operating temperature of the receiving card, and the setting parameter threshold corresponding to the historical operating temperature of the receiving card is 80 degrees Celsius (℃). When the historical operating temperature of the receiving card is greater than or equal to 80℃, it is determined that the display screen is abnormal; when the historical operating temperature of the receiving card is less than 80℃, it is determined that the display screen is not abnormal.

[0049] As an example, the historical operating parameter is the historical operating temperature of the light source module, and the set parameter threshold corresponding to the historical operating temperature of the light source model is 75°C. When the historical operating temperature of the light source module is greater than or equal to 75°C, it is determined that the display screen is abnormal; when the historical operating temperature of the light source module is less than 75°C, it is determined that the display screen is not abnormal.

[0050] As an example, the control module is a receiving card, the historical operating parameters are the historical operating temperature of the receiving card and the historical operating temperature of the light source module, and the set parameter thresholds include a first set parameter threshold corresponding to the historical operating temperature of the receiving card and a second set parameter threshold corresponding to the historical operating temperature of the light source module. The first set parameter threshold is 75°C and the second set parameter threshold is 85°C.

[0051] When the historical operating temperature of the receiving card is greater than or equal to 75°C, and / or the historical operating temperature of the light source module is greater than or equal to 85°C, it is determined that the display screen is abnormal; when the historical operating temperature of the receiving card is less than 75°C, and the historical operating temperature of the light source module is less than 85°C, it is determined that the display screen is not abnormal.

[0052] It should be noted that the type of control module, the type of historical operating parameters, and the value of the set parameter threshold are not limited here, and can be set according to actual needs.

[0053] In some embodiments, when the terminal device determines that the display screen is abnormal based on the set parameter threshold and the historical operating parameters, the target parameter difference of the rated operating parameters of the display screen can be calculated, and the target parameter difference can be used to determine the target abnormality level corresponding to the target parameter difference from the set abnormality level mapping information. The set abnormality level mapping information is used to characterize the corresponding relationship between the parameter difference and the abnormality level, and the set abnormality level mapping information can be an abnormality level table or an abnormality level function.

[0054] As an example, the historical operating parameter is the historical operating temperature of the receiving card, and the parameter difference is the receiving card temperature difference. The abnormal level mapping information is set to an abnormal level table, and the corresponding relationship between the receiving card temperature difference and the abnormal level can be shown in Table 1, that is, the abnormal level table. Table 1 shows the abnormal levels corresponding to different receiving card temperature differences. According to the corresponding relationship, the target abnormal level corresponding to the target receiving card temperature difference can be obtained.

[0055] Table 1

[0056] Receiving card temperature difference (℃) Abnormal Level ≤5 0 6-10 1 10-15 2 ≥16 3

[0057] It should be noted that the corresponding relationship between the temperature difference of the receiving card and the abnormal level is not limited to that shown in Table 1, and can be specifically set according to actual needs.

[0058] As an example, the historical operating parameter is the historical operating temperature of the light source module, and the parameter difference is the light source module temperature difference ΔT. The abnormal level mapping information is set to the abnormal level function, and the abnormal level function is Ab(n)=f(ΔT), where Ab(n) is the abnormal level, and f(ΔT) is the mapping relationship between the light source module temperature difference ΔT and the abnormal level Ab(n).

[0059] The terminal device can calculate the target abnormality level Ab(n)' according to the target light source module temperature difference ΔT' according to the following formula:

[0060] Ab(n)'=f(ΔT').

[0061] The abnormality level function calculates the corresponding target abnormality level Ab(n)', which is the target abnormality level.

[0062] In some embodiments, when the terminal device determines that an abnormality occurs on the display screen based on historical operating parameters, the historical operating parameters can be input into a first deep learning network model. The first deep learning network model receives and responds to the historical operating parameters, and outputs a target abnormality level corresponding to the historical operating parameters to the terminal device. The terminal device receives the target abnormality level output by the first deep learning network model.

[0063] Among them, the first deep learning network model can be a Convolutional Neural Networks (CNN) model, a Deep Belief Networks (DBN) model, a Stacked Auto Encoder Networks (SAE) model, a Recurrent Neural Networks (RNN) model, a Deep Neural Networks (DNN) model, a Long Short-Term Memory (LSTM) network model or a Gated Recurring Units (GRU) model, etc. The type of the first deep learning network model is not limited here and can be set according to actual needs.

[0064] In some embodiments, the terminal device can determine the target operating parameter corresponding to the target abnormality level from the setting parameter mapping table according to the target abnormality level. The setting parameter mapping table can be used to characterize the correspondence between the abnormality level and the operating parameter; the operating parameter can be at least one of display brightness, operating voltage or operating current.

[0065] As an example, the parameter mapping table is set as the first parameter table, the working parameter can be display brightness, the abnormal level includes 0, 1, 2, 3, and the display brightness includes display brightness including L (nits), 90% L (nits), 70% L (nits), 50% L (nits), etc. The corresponding relationship between the abnormal level and the display brightness can be shown in Table 2, that is, the first parameter table. Table 2 shows the display brightness corresponding to different abnormal levels. According to the corresponding relationship, the target display brightness corresponding to the target abnormal level can be obtained.

[0066] Table 2

[0067] Abnormal Level Display brightness (nits) 0 L 1 90％L 2 70％L 3 50％L

[0068] It should be noted that the corresponding relationship between the abnormal level and the display brightness is not limited to that shown in Table 2, and can be set according to actual needs.

[0069] In some embodiments, the terminal device can input the target abnormality level into the second deep learning network model, the second deep learning network model receives and responds to the target abnormality level, outputs the target operating parameters corresponding to the target abnormality level to the terminal device, and the terminal device receives the target operating parameters output by the second deep learning network model.

[0070] Among them, the second deep learning network model can be a Convolutional Neural Networks (CNN) model, a Deep Belief Networks (DBN) model, a Stacked Auto Encoder Networks (SAE) model, a Recurrent Neural Networks (RNN) model, a Deep Neural Networks (DNN) model, a Long Short-Term Memory (LSTM) network model or a Gate Recurring Units (GRU) model, etc. The type of the second deep learning network model is not limited here and can be set according to actual needs.

[0071] In some implementations, the setting parameter mapping table can also be used to characterize the correspondence between the abnormality level and the service life. The terminal device can determine the target service life corresponding to the target abnormality level from the setting parameter mapping table according to the target abnormality level, and display the target service life, so that the user can maintain the display screen in time according to the service life of the display screen, thereby improving the user's maintenance experience of maintaining the display screen.

[0072] As an example, the parameter mapping table is set to the second parameter table, and the correspondence between the abnormality level and the service life can be shown in Table 3, that is, the second parameter table. Table 3 shows the service life corresponding to different abnormality levels. According to the correspondence, the target service life corresponding to the target abnormality level can be obtained.

[0073] Table 3

[0074] Abnormal Level Service life (years) 0 10 1 8 2 6 3 3

[0075] It should be noted that the corresponding relationship between the abnormal level and the service life is not limited to that shown in Table 3, and can be set according to actual needs.

[0076] As an example, the terminal device is provided with a display interface, and the terminal device can determine the target service life corresponding to the target abnormality level from a setting parameter mapping table according to the target abnormality level, and display the target service life on the display interface.

[0077] As an example, the terminal device can determine the target service life corresponding to the target abnormality level from the set parameter mapping table according to the target abnormality level, and send the target service life to the control module. The control module receives and responds to the target service life, and controls the target light source module to display the target service life.

[0078] Step S130: According to the target operating parameters, the display screen is controlled to emit light at the target display brightness.

[0079] In an embodiment of the present application, when the terminal device determines that the display screen has an abnormality based on historical operating parameters, after determining the corresponding target operating parameters, the display screen can be controlled to illuminate at the target display brightness according to the target operating parameters. This achieves the automatic reduction of the display brightness of the display screen when the display screen is determined to have an abnormality based on the historical operating parameters of the display screen, thereby reducing the thermal resistance of the display screen when it is operating abnormally, and ensuring that the display screen has a longer service life.

[0080] Specifically, when the terminal device determines that the display screen is abnormal based on historical operating parameters, after determining the corresponding target working parameters, the target working parameters can be sent to the control module. The control module receives and responds to the target working parameters, and controls the light source module to emit light at the target display brightness.

[0081] The solution provided by the present application obtains historical operating parameters of a display screen, and when it is determined that the display screen is abnormal based on the historical operating parameters, determines target operating parameters, the target display brightness corresponding to the target operating parameters is lower than the historical display brightness corresponding to the historical operating parameters, and according to the target operating parameters, controls the display screen to emit light at the target display brightness, thereby automatically reducing the display brightness of the display screen when it is determined that the display screen is abnormal based on the historical operating parameters of the display screen, reducing the thermal resistance of the display screen when it is working abnormally, and ensuring that the display screen has a long service life.

[0082] See also Figure 3 , which shows a flow chart of a display screen control method provided by another embodiment of the present application. In a specific embodiment, the display screen control method can be applied to Figure 1 The terminal device 100 in the display screen control system shown in FIG. 1 is taken as an example below. Figure 3 The process shown is described in detail, and the display screen control method may include the following steps S210 to S250.

[0083] Step S210: Obtain historical operating parameters of the display screen.

[0084] Step S220: When it is determined that the display screen is abnormal based on the historical operating parameters, the target operating parameters are determined.

[0085] Step S230: According to the target working parameters, the display screen is controlled to emit light at the target display brightness.

[0086] In this embodiment, step S210, step S220 and step S230 may refer to the contents of the corresponding steps in the aforementioned embodiments, which will not be described in detail here.

[0087] Step S240: Acquire the current working parameters of the display screen.

[0088] In this embodiment, after the terminal device controls the display screen to emit light at the target display brightness according to the target operating parameters, the current operating parameters of the display screen can be obtained. The current operating parameters can be any one of the current display brightness, current operating temperature, current operating voltage or current operating current corresponding to the light source module.

[0089] In some embodiments, the display screen control system may further include an image acquisition module, which may be connected to a terminal device via a network and perform data exchange with the terminal device. The image acquisition module may be used to acquire a light-emitting image of the light source module.

[0090] The current working parameter is the current display brightness of the light source module. After the terminal device controls the display screen to display light at the target display brightness according to the target working parameter, the terminal device can send a first instruction to the image acquisition module through the network. The image acquisition module receives and responds to the first instruction, collects the light-emitting image of the light source module, and sends the collected light-emitting image to the terminal device through the network. The terminal device receives the light-emitting image returned by the image acquisition module, analyzes the light-emitting image, and obtains the current display brightness corresponding to the light-emitting image.

[0091] In some embodiments, the current operating parameter is the current operating temperature of the light source module. After the terminal device controls the display screen to emit light at the target display brightness according to the target operating parameter, the terminal device can send a second instruction to the control module through the network. The control module receives and responds to the second instruction, collects the operating temperature of the light source module, obtains the corresponding current operating temperature, and sends the current operating temperature to the terminal device through the network. The terminal device receives the current operating temperature returned by the control module.

[0092] In some embodiments, the current operating parameter is the current operating voltage of the light source module. After the terminal device controls the display screen to illuminate at the target display brightness according to the target operating parameter, the terminal device can send a third instruction to the control module through the network. The control module receives and responds to the third instruction, collects the operating voltage of the light source module, obtains the corresponding current operating voltage, and sends the current operating voltage to the terminal device through the network. The terminal device receives the current operating voltage returned by the control module.

[0093] In some embodiments, the current operating parameter is the current operating current of the light source module. After the terminal device controls the display screen to emit light at the target display brightness according to the target operating parameter, the terminal device can send a fourth instruction to the control module through the network. The control module receives and responds to the fourth instruction, collects the operating current of the light source module, obtains the corresponding current operating current, and sends the current operating current to the terminal device through the network. The terminal device receives the current operating current returned by the control module.

[0094] Step S250: When it is determined according to the current working parameters that the current working state of the display screen is an abnormal working state, an alarm prompt message is generated.

[0095] In this embodiment, after acquiring the current working parameters of the display screen, the terminal device can determine whether the current working state of the display screen is abnormal according to the current working parameters, and generate an alarm prompt information when the current working state of the display screen is determined to be abnormal according to the current working parameters, so that the user can handle the abnormal working state of the display screen according to the alarm prompt information, which can avoid the display screen from having a poor display effect due to abnormal operation, and can ensure that the display screen has a better display effect. Among them, the alarm information can be at least any one of voice alarm prompt information, light alarm prompt information, or text alarm prompt information.

[0096] Specifically, the terminal device can determine whether the current working state of the display screen is abnormal based on the current working parameters and the preset working parameter range. When the current working parameters are within the preset working parameter range, it is determined that the current working state of the display screen is normal; when the current working parameters are not within the preset working parameter range, it is determined that the current working state of the display screen is abnormal.

[0097] In some embodiments, the current operating parameter is the current display brightness of the light source module, and the preset operating parameter range is the preset brightness range. When the current display brightness is within the preset brightness range, it is determined that the current operating state of the display screen is normal; when the current display brightness is not within the preset brightness range, it is determined that the current operating state of the display screen is abnormal.

[0098] In some embodiments, the current operating parameter is the current operating temperature of the light source module, and the preset operating parameter range is the preset temperature range. When the current operating temperature is within the preset temperature range, it is determined that the current operating state of the display screen is normal; when the current operating temperature is not within the preset temperature range, it is determined that the current operating state of the display screen is abnormal.

[0099] In some embodiments, the current operating parameter is the current operating voltage of the light source module, and the preset operating parameter range is the preset voltage range. When the current operating voltage is within the preset voltage range, it is determined that the current operating state of the display screen is normal; when the current operating voltage is not within the preset voltage range, it is determined that the current operating state of the display screen is abnormal.

[0100] In some embodiments, the current operating parameter is the current operating current of the light source module, and the preset operating parameter range is the preset current range.
