As shown in fig. 1 and fig. 2, the LED display screen includes a controller, an LED array, and a plurality of driver chips, each driver chip includes a plurality of driver ports, and each driver port is used for driving a column of LED strings.
The controller is used for converting the display image data output by the video source into a gray scale data signal and a control signal and transmitting the gray scale data signal and the control signal to the driving chip. The driving chip determines the opening time or the closing time of the driving port according to the control signal, and the driving chip determines the opening duration of the driving port according to the gray data signal. As shown in fig. 2, drive port opening method 1: the driving port is opened at the y +1 th moment according to the control signal, and the gray data signal controls the driving port to open m gray clock cycles. Drive port open mode 2: the driving port is closed at the y + m th moment according to the control signal, and the gray data signal controls the driving port to open m gray clock cycles.
When the driving port is opened, the LED lamp strings in the row corresponding to the closed driving port discharge through the opened driving port, and the discharged LED lamp strings influence the opening response speed of the driving port. As shown in fig. 1, the first driving port is turned ON (ON), the other three driving ports are turned OFF (OFF), and the LED string corresponding to the turned-OFF driving port discharges to the turned-ON driving port. At the same time, the number of the opened driving ports is changed, the number of the driving ports in the closed state is changed, and the number of the discharged LED lamp strings is changed. The change of the number of the discharged LED lamp strings can cause the change of the starting response speed of the driving port, so that the starting response speed of the driving port is inconsistent, and the display effect is influenced.
Based on the above problem, an embodiment of the present application provides a configuration method of an LED display screen, as shown in fig. 3, the LED display screen includes a plurality of driving chips, the number of driving ports included in each driving chip is the same, and the configuration method of the LED display screen includes step S301 and step S302.
Step S301, configuring first address information for each driver chip, where the first address information corresponding to different driver chips is different.

Specifically, by configuring first address information and first start-up information for the driver chips, when the driver chips are driven, the target driver chips to be started can be determined by the first address information, and because each driver chip is configured with the first start-up information, each first start-up information corresponds to one first start-up time, the first start-up information corresponding to different driver chips is different, and the first start-up times corresponding to different first start-up information are different. Therefore, only one driving chip is started at the same time, and because the number of the driving ports included in each driving chip is the same, the number of the started driving ports is the same at the same time, the number of the driving ports in the closed state is the same, the number of the discharged LED lamp strings is the same, and the starting response speeds of the driving ports are the same.

Then, the first start-up information is configured for each driver chip, for example, as shown in fig. 4, the on time of the driver chip with address Add _1-1 is set as the x-th gray scale clock signal, the on time of the driver chip with address Add _1-2 is set as the x + 1-th gray scale clock signal, the on time of the driver chip with address Add _1-n is set as the x + n-1-th gray scale clock signal, and the on time of the driver chip with address Add _ n-n is set as the z + n-1-th gray scale clock signal.
Through the configuration, at most one driving chip can execute the starting action at the same time. And because the number of the driving ports included in each driving chip is the same, the number of the started driving ports is the same, the number of the driving ports in the closed state is the same, the number of the discharged LED lamp strings is the same, and the starting response speeds of the driving ports are the same at the same time.
In an embodiment of the present application, the method for configuring an LED display screen further includes step S303 and step S304.
Step S303, multiple sets of corresponding first address information and first start information are obtained.
Step S304, storing a plurality of groups of corresponding first address information and first startup information.
Specifically, the first address information and the first start-up information are associated, and then the associated first address information and the associated first start-up information are stored. When the driving chip is driven, the target driving chip to be started can be determined by acquiring the first address information in the control signal. And then, determining corresponding first starting information through the first address information, and determining the starting time of the target drive chip. When the target drive chip is started, other drive chips cannot be started, and only one drive chip is started at the same time. Therefore, the number of the driving ports which are started at the same time is consistent, the number of the driving ports which are in a closed state is the same, the number of the discharged LED lamp strings is the same, and the starting response speed of the driving ports is consistent.

Referring to fig. 5, the LED display screen includes a plurality of driving chips, each driving chip includes a plurality of driving ports, and the configuration method of the LED display screen includes steps S501 and S502.
Step S501, configuring second address information for each driving port, where the second address information corresponding to different driving ports is different.
Step S502, configuring second start information for each driving port, where each second start information corresponds to a second start time, the second start information corresponding to different driving ports is different, and the second start times corresponding to different second start information are different.
Specifically, the second address information and the second start information are configured for the drive port, and when the drive port is driven, the target drive port to be started can be determined through the second address information. Therefore, only one driving port is started at the same time, the number of the driving ports in the closed state is the same, the number of the discharged LED lamp strings is the same, and the starting response speeds of the driving ports are the same.
In an embodiment of the present application, the method for configuring the LED display screen further includes step S503 and step S504.
Step S503, a plurality of sets of corresponding second address information and second start-up information are obtained.

When the driving port is driven, the target driving port to be opened can be determined by acquiring the second address information in the control signal. And then, determining corresponding second starting information through the second address information, and determining the starting time of the target drive port. When the target drive port is started, other drive ports cannot be started, so that only one drive port is started at the same time, the number of the drive ports in the closed state is unchanged, the number of the discharged LED lamp strings is unchanged, and the starting response speeds of the drive ports are consistent.

In step S601, first control signal information and first gray data information are acquired.
Specifically, the controller in the LED display screen converts the display image data output by the video source into a first gray data signal and first control signal information, and transmits the first gray data signal and the first control signal information to the driving chip. Therefore, the driving chip can acquire the first gray data signal and the first control signal information.
