Abstract

The present disclosure discloses a display adjustment method and device for a bar-shaped electronic shelf label. The method according to the present disclosure includes: configuring a mobile terminal to be coupled with a bar-shaped electronic shelf label and obtain status information of display elements displayed on a display interface of the bar-shaped electronic shelf label; changing, by the mobile terminal, the position information of a display element from a first position information to a second position information and generating an element position adjustment instruction; configuring the bar-shaped electronic shelf label to receive the element position adjustment instruction, change the position of the display element from the first position to the second position in response to the element position adjustment instruction, and display the display element on the display interface of the bar-shaped electronic shelf label.

First claim

We claim:

1. A display adjustment method performed at a mobile terminal for a bar-shaped electronic shelf label, the method comprising:
communicatively coupling, by the mobile terminal, with the bar-shaped electronic shelf label;
obtaining, by the mobile terminal, status information of display elements displayed on a display interface of the bar-shaped electronic shelf label, the status information of the display elements comprising at least position information of the display elements in the display interface;
changing, by the mobile terminal, the position information of a display element from a first position information to a second position information and generating an element position adjustment instruction; and
sending, by the mobile terminal, the element position adjustment instruction to the bar-shaped electronic shelf label to instruct the bar-shaped electronic shelf label to change the position of the display element from the first position to the second position,
wherein after changing, by the mobile terminal, the position information of the display element from a first position information to a second position information, the method further comprises:
obtaining, by the mobile terminal, a size of the bar-shaped electronic shelf label, corresponding start position and end position of the adjusted element in the mobile terminal, and a final position of a final element in the mobile terminal;
calculating, by the mobile terminal, an adjustment ratio of the adjusted element according to the start position, the end position, and the final position;
determining, by the mobile terminal, as an adjustment distance of the adjusted element, a product of the adjustment ratio and the size of the bar-shaped electronic shelf label.

2. The method of claim 1 , wherein the status information of the display elements further comprises information on a number of display elements and position information of each display element in the bar-shaped electronic shelf label, and wherein the step of generating the element position adjustment instruction comprises:
determining, by the mobile terminal, an adjusted position, in the bar-shaped electronic shelf label, of the adjusted element according to the position, in the bar-shaped electronic shelf label, of the adjusted element and the adjustment distance;
generating, by the mobile terminal, the element position adjustment instruction according to the adjusted position, in the bar-shaped electronic shelf label, of the adjusted element.

3. The method of claim 1 , wherein before communicatively coupling, by the mobile terminal, with the bar-shaped electronic shelf label, the method further comprises:
receiving, by the mobile terminal, login information and verifying a user's identity according to the login information;
when the verification is passed, triggering, by the mobile terminal, scan communicable bar-shaped electronic shelf labels, sorting and outputting the communicable bar-shaped electronic shelf labels according to strengths of communication signals so as to display the communicable bar-shaped electronic shelf labels in the mobile terminal;
sending, by the mobile terminal, a communication establishment request, the communication establishment request carrying identification information of the bar-shaped electronic shelf label to be communicated.

4. The method of claim 3 , further comprising:
scanning, by the mobile terminal, broadcast information sent by the bar-shaped electronic shelf label at preset time intervals, the broadcast information carrying identification information of the bar-shaped electronic shelf label;
sending, by the mobile terminal, the login information to the bar-shaped electronic shelf label and requesting the bar-shaped electronic shelf label to verify the user's identity according to the login information, when the mobile terminal requests and attempts to establish communication with the bar-shaped electronic shelf label according to the broadcast information.

5. The method of claim 1 , wherein the step of obtaining, by the mobile terminal, status information of display elements displayed on a display interface of the bar-shaped electronic shelf label comprises:
sending, by the mobile terminal, a display element status information obtaining request to instruct the bar-shaped electronic shelf label to extract the status information of the display elements and send encrypted status information of the display elements as a request response message;
receiving, by the mobile terminal, the request response message, the request response message carrying a display element status characteristic value corresponding to the status information of the display elements; and
analyzing, by the mobile terminal, the display element status characteristic value to obtain the status information of the display elements.

6. A mobile terminal for adjusting display of a bar-shaped electronic shelf label, comprising:
a processor;
a memory storing instructions that, when executed by the processor, cause the processor to:
communicatively couple, by the mobile terminal, with the bar-shaped electronic shelf label;
obtain, by the mobile terminal, status information of display elements displayed on a display interface of the bar-shaped electronic shelf label, the status information of the display elements comprising at least position information of the display elements in the display interface;
change, by the mobile terminal, the position information of a display element from a first position information to a second position information and generate an element position adjustment instruction; and
send, by the mobile terminal, the element position adjustment instruction to the bar-shaped electronic shelf label to instruct the bar-shaped electronic shelf label to change the position of the display element from the first position to the second position,

wherein the instructions, when executed by the processor, further cause the processor to:
obtain, by the mobile terminal, a size of the bar-shaped electronic shelf label, corresponding start position and end position of the adjusted element in the mobile terminal, and a final position of a final element in the mobile terminal;
calculate, by the mobile terminal, an adjustment ratio of the adjusted element according to the start position, the end position and the final position;
determine, by the mobile terminal, as an adjustment distance of the adjusted element, a product of the adjustment ratio and the size of the bar-shaped electronic shelf label.

7. The mobile terminal of claim 6 , wherein the status information of the display elements further comprises information on a number of display elements and position information of each display element in the bar-shaped electronic shelf label, and the instructions, when executed by the processor, further cause the processor to:
determine, by the mobile terminal, an adjusted position, in the bar-shaped electronic shelf label, of the adjusted element according to the position, in the bar-shaped electronic shelf label, of the adjusted element and the adjustment distance; and
generate, by the mobile terminal, the element position adjustment instruction according to the adjusted position, in the bar-shaped electronic shelf label, of the adjusted element.

8. The mobile terminal of claim 6 , wherein the instructions, when executed by the processor, further cause the processor to:
receive, by the mobile terminal, login information and verify the user's identity according to the login information;
