In the related art, the daisy chain function of signals is realized by controlling other devices (slave display devices) by a master display device (PC source), and a specific control process can be referred to as fig. 1. Specifically, the master display device 100 is directly connected to the first slave display device 101; the first slave display device 101 is reconnected to the second slave display device 102; the second slave display device 102 is connected with a third slave display device 103; wherein the first slave display device 101, the second slave display device 102, and the third slave display device 103 are directly output signals and controlled by the master display device 100; that is, the second slave display device 102 is connected to the master display device 100 through the first slave display device 101, and the third slave display device 103 is connected to the master display device 100 through the second slave display device 102 and the first slave display device 101.
The present exemplary embodiment first provides a display device control method that may be applied to a display device including a plurality of display devices connected in a Daisy chain (Daisy chain); the display devices may be connected through Type-C (universal serial bus based upper and lower parallel interfaces), or may be connected through other manners, for example, through a Universal Serial Bus (USB) interface, or through a DP (display interface), and the like, which is not limited in this example; the Type-C interface is USB Type-C, USB-C for short, and is a USB hardware interface specification. Type-C has faster transmission speed (up to 10Gbps) and more convenient power transmission (up to 100W). Referring to fig. 2, the display apparatus control method may include the steps of:
s210, obtaining the extended display identification data of the display equipment, and determining the main display equipment according to the product serial number in the extended display identification data.
And S220, determining other display devices except the main display device in the display devices as slave display devices, and calculating the total number of the slave display devices.
Step S230, calculating the total power required by the slave display equipment according to the total number of the slave display equipment, and configuring the power output power of the master display equipment according to the total power.
And S240, processing the objects to be displayed according to the total number of the secondary display devices to obtain a plurality of secondary display objects, and displaying the plurality of secondary display objects.
In the display device control method, on one hand, the problem that power supplies cannot be provided among the display devices in the prior art is solved by determining the main display device and configuring the power supply output power for the main display device according to the total power required by the auxiliary display device, so that the main display device can provide sufficient power supplies for the auxiliary display device; on the other hand, the objects to be displayed are processed according to the total number of the slave display devices to obtain a plurality of sub display objects, and then the sub display objects are sequentially displayed, so that data transmission between the master display device and the slave display devices is realized, and the problem that data transmission cannot be performed between the display devices in the prior art is solved.
Hereinafter, each step in the above-described display apparatus control method in the present exemplary embodiment will be explained and explained in detail with reference to the drawings.
In step S210, extended display identification data of the display device is obtained, and a main display device is determined according to a product serial number in the extended display identification data.
In the present exemplary embodiment, each Display device will capture Extended Display Identification Data (EDID) of the next Display device; wherein, there will be a 13-bit SN (Serial Number, product Serial Number) in the extended identification data, and the SN can be used as the physical address of each display device; of course, in other exemplary embodiments of the present disclosure, other identification data may be adopted as the extended display identification data by those skilled in the art. Optionally, after capturing the extended display identification data, first, broadcasting a product serial number in the extended display identification data; and then, comparing the broadcasted product serial number with the local product sequence to obtain a comparison result, and determining the main display equipment according to the comparison result. Specifically, after the SN of the EDID is captured, all the accessed display devices can be broadcasted through the whole network in a manner of, for example, a USB pin (USB pin), and each display device collects all broadcasted SN signals and compares the collected signals with the local SN, and if the same SN can be found, the display device is a slave device; if no match is found, the host is the host. Optionally, by the method, the main display equipment can be freely selected, so that the loss of the equipment caused by fixing the same display equipment as the long-term main display equipment is avoided, and the service life of the equipment is shortened.
In step S220, the other display devices except the master display device are determined as slave display devices, and the total number of the slave display devices is calculated.
In this exemplary embodiment, after the main display device is determined, other display devices except the main display device may be used as slave display devices, then the total number of the slave display devices is calculated, then the slave display devices are encoded, and the encoding is verified. Specifically, referring to fig. 3, numbering may be performed in a manner that a previous station sends a number to a next station, starting from the main display device 301, the number of the main display device may be 0, and the main display device notifies the next slave display device 302 of the number 1 through a USB function in a Type-C interface; the slave display equipment 1 adds 1 to the number of the slave display equipment and then sends the number to the next slave display equipment, and so on, numbers are given to all the access slave display equipment; optionally, the last slave display device has no SN information of the EDID of the next slave display device, so that the number may be sent forward from the last slave display device by subtracting 1, and each display device checks whether its number is correct, and re-encodes according to the above steps if it is wrong. By sequentially encoding the slave display devices, the total number of the slave display devices is prevented from being calculated incorrectly, and therefore the master display device cannot provide sufficient power for each slave display device.
In step S230, calculating a total power required by the slave display devices according to the total number of the slave display devices, and configuring a power output power of the master display device according to the total power.
In the present exemplary embodiment, first, the total power required by the slave display devices is calculated from the total number of the slave display devices and the power consumption of the slave display devices; the power supply output power of the main display device is then configured according to the total power.
Optionally, in this example embodiment, calculating the total power required by the slave display devices according to the total number of the slave display devices and the power consumption of the slave display devices includes: detecting whether the total number of the slave display devices changes; and if the total number of the slave display devices is detected to be changed, calculating the total power required by the slave display devices according to the changed number of the slave display devices and the power consumption of the slave display devices. In detail:
for example, whether a new slave display device is accessed is detected; then, if it is detected that a new slave display device is accessed, the total power required by the slave display device is calculated by using the last newly accessed slave display device according to the changed number of the slave display devices and the power consumption of the slave display devices. For example, the last slave display device (the slave display device with the largest code, for example, the slave display device with the code 4) may detect whether a new slave display device is accessed later; if the slave display device with the largest code detects that a new slave display device is accessed again, the total power required by the slave display device can be calculated by using the newly accessed slave display device (for example, the code of the newly accessed slave display device can be 5) according to the number of the changed slave display devices and the power consumption of the slave display device. By the method, the situation that the slave display equipment cannot be satisfied due to the fact that the power supply output power of the master display equipment is too small due to the increase of the total number of the slave display equipment is avoided.
As another example, detecting whether a slave display device is lost; then, if it is detected that there is a loss of the slave display devices, the last slave display device of the lost slave display devices is used to calculate the total power required by the slave display devices according to the number of changed slave display devices and the power consumption of the slave display devices. For example, the master display device and each slave display device can detect whether the display device connected behind the display device is lost or not; optionally, if the master display device detects that the slave display device connected to the rear is lost, the master display device only needs to provide power for itself; if the slave display device detects that other slave display devices connected later are lost, the number of the remaining slave display devices can be directly calculated according to the code of the slave display device, and then the total power required by the slave display devices can be calculated according to the number of the remaining slave display devices and the power consumption of the slave display devices. By the method, waste caused by too much power output of the power supply configured by the main display equipment due to reduction of the total number of the auxiliary display equipment is avoided.
Alternatively, as shown in fig. 3, since the power supply is consumed by the conversion (DC to DC), the power output of the power supply of the main display device can be determined according to the number of the slave display devices that are actually connected and the total power requirement, and the output current is changed according to the back-end power requirement, so as to change the power output; when a new slave display device is accessed, a power summarizing statistical demand can be initiated by the newly accessed slave display device; alternatively, when any slave display device discovers that its next slave display device is missing, the power summary statistics need may be initiated by the slave display device that discovered the missing slave display device. Accordingly, the master display device 301 may provide power to the slave display device 302 through the Type-C interface.
Optionally, in this example embodiment, calculating the total power required by the slave display devices according to the total number of the slave display devices and the power consumption of the slave display devices may further include: detecting whether power consumption of the slave display device is changed; and if the power consumption of the slave display equipment is detected to be changed, calculating the total power required by the slave display equipment according to the changed power consumption of the slave display equipment and the total number of the slave display equipment. For example, when a change in the power consumption of any one of the display devices is detected, a power consumption summary statistical requirement is initiated by the display device, for example: some display devices adjust the brightness output of the display device, and some external USB devices are connected to some display devices.
In step S240, the object to be displayed is processed according to the total number of the slave display devices to obtain a plurality of sub-display objects, and the plurality of sub-display objects are displayed.
In the present exemplary embodiment, first, the object to be displayed may be cut into a plurality of sub-display objects that are the same as the total number according to the total number of the slave display devices; or copying the object to be displayed according to the total number of the slave display devices to obtain a plurality of sub-display objects which are the same as the total number; secondly, respectively carrying out packaging processing on the plurality of sub-display objects to obtain a plurality of target display objects; then, coding a plurality of target display objects; wherein the codes of the plurality of target display objects correspond to the codes of the slave display device one to one; and finally, sequentially displaying the plurality of sub display objects according to the codes of the slave display equipment and the target display object. By coding the sub-display objects, the display result errors caused by sequence errors in the display process are avoided.
Fig. 4 schematically shows a flow chart of a method for sequentially displaying the plurality of target display objects according to the coding of the slave display device and the coding of the target display objects. Referring to fig. 4, sequentially displaying the plurality of target display objects according to the codes of the slave display devices and the codes of the target display objects may include steps S410 to S440, which will be described in detail below.
In step S410, the plurality of target display objects is transmitted to a first slave display device.
In step S420, caching, by the first slave display device, a target display object with the same code as that of the first slave display device;
in step S430, the first slave display device is used to delete the target display object with the same code as the first slave display device from the plurality of target display objects, and send the remaining plurality of target display objects to the next slave display device until the slave display device has the target display object with the same code as the slave display device buffered.
Next, steps S410 to S430 are explained and explained. Firstly, in order to avoid attenuation of signals in the process of continuous copying, each display device needs to perform signal calibration when outputting signals; since both are digital signal outputs, the quality of the output signal eye pattern, i.e. the swing (oscillation) of the calibration voltage, needs to be calibrated; then, with continued reference to fig. 3, the master display device 301 may send the plurality of target display objects to a first slave display device (the first slave display device may be, for example, a slave display device next to the master display device, the first slave display device may have a code of 1, and the other slave display devices may have a code of 2,3, …) 302; when the first slave display device receives the packets of a plurality of target display objects, the target display object corresponding to the code of the first slave display device (the target display object with the code of 1) can be cached; and then deleting the target display objects which are cached in the packets of the plurality of target display objects (deleting the target display objects coded as 1 in the packets), and sending the remaining plurality of target display objects to the next slave display device (the slave display device coded as 2) until the slave display devices cache the target display objects with the same codes as the slave display devices. It should be noted that, the first slave display device may be a slave display device with a code of 1, or may be a slave display device with another code, and the first slave display device may be determined according to the code of the slave display device connected to the master display device, which is not limited in this example.
Fig. 5 schematically illustrates another display device control method. Referring to fig. 5, the display apparatus control method may further include steps S510 to S530, which will be described in detail below.
In step S510, a touch operation applied to the sub-display objects is detected, and touch coordinates of the touch operation are determined.
In step S520, the touch coordinates are analyzed to obtain an analysis result, and a touch event is generated according to the analysis result.
First, in this exemplary embodiment, if the plurality of sub display objects are obtained by cutting the object to be displayed, the touch coordinates in each sub display object may be converted into touch coordinates of the object to be displayed, and the touch event is generated according to the touch coordinates of the object to be displayed; optionally, as shown in fig. 6, since the main display device outputs a complete picture of one frame, and the MCU of the main display device splits the N modules, which are equal to the total number of the slave display devices, in this case, when there is a touch behavior, the MCU needs to convert the coordinate position sent from the slave display device into the position coordinate corresponding to the whole picture, and then sends the position coordinate to the main display device. The problem that the response cannot be carried out or the response is disordered when the display devices with different numbers send the same touch coordinates is avoided.
Optionally, specifically, the scaling the coordinate position sent from the display device may include: for example, as shown in fig. 6, a picture to be displayed is divided into four parts, and the four parts are sequentially encoded into 1,2,3, and 4 from top to bottom from left to right; when the touch coordinates sent by the slave display device corresponding to the codes are received, the touch coordinates of the slave display device corresponding to the codes can be corresponded to the picture to be displayed corresponding to the codes in an equal-scale reduction mode. The resolution of the main display device is the same as that of the slave display device by default, so that after the touch coordinate sent by the slave display device with the code of 1 is received, the coordinate can be directly reduced by four times in an equal proportion to be the coordinate of the picture to be displayed; optionally, after receiving the touch coordinate sent from the display device and coded as 2, the coordinate may be first reduced by four times in an equal proportion, then the horizontal coordinate of the touch coordinate in the picture to be displayed is obtained by adding the reduced horizontal coordinate to the half of the length of the picture to be displayed, and then the reduced vertical coordinate is used as the vertical coordinate of the touch coordinate in the picture to be displayed; the coordinates of the touch coordinates of the other coded slave display devices in the image to be displayed are similar to the above calculation method, and are not described herein again.
Optionally, in this exemplary embodiment, if the plurality of sub-display objects are obtained by copying the object to be displayed, it may be determined whether the multi-touch operation is a one-touch behavior or a multi-touch behavior according to the codes of the plurality of slave display devices and the touch coordinates of the slave display devices; if the multi-touch operation is judged to be a one-touch behavior, generating a touch event according to the touch coordinate; and if the multi-touch operation is a multi-touch behavior, generating a plurality of touch events according to the touch coordinates. Wherein, determining whether the touch operation is a one-touch behavior or a multi-touch behavior according to the codes of the plurality of slave display devices and the touch coordinates of the slave display devices may include: if the codes of the plurality of slave display devices are different and the touch coordinates of the slave display devices are the same, judging that the touch operation of the plurality of slave display devices is a one-time touch behavior; and if the codes of the slave display devices are the same and the touch coordinates of the slave display devices are the same, judging that the multi-touch operation of the slave display devices is a multi-touch behavior.
For example, referring to fig. 7, when all touch responses of the slave display devices 302 are transmitted to the master display device 301 through the USB function of the Type-C interface, the MCU of the master display device performs a comparative analysis on all touch coordinate information; if the touch coordinates of the devices with different numbers are the same, the touch behavior can be judged to be one-time touch behavior, and one coordinate can be sent to the main display device. If the same coordinates appear twice or more on the same numbered device, the touch behaviors are twice or more, and the coordinates are sent twice or more to the main display device.
In step S530, the touch event is executed based on the object to be displayed.
