Picture data processing device, picture data processing method and electronic tag display system component

Abstract

The invention provides a picture data processing device, a picture data processing method and an electronic tag display system component. The picture data processing device comprises a wireless reception module, a memory, a processor and a wired transmission module, wherein the wireless reception module is used for receiving a wireless data signal which comprises character data and display rule instruction data; the memory is used for storing data; the processing is used for calling a display rule instruction to generating the character data received by the wireless reception module into dot matrix picture data; and the wired transmission module is in wired connection with at least one dot matrix display screen and is used for sending the picture data generated by the processing module tothe dot matrix display screen. The wireless reception module receives the wireless data signal which comprises the character data and the display rule instruction data; the processor compiles the character data into dot matrix picture data which is displayed by the display screen; and the character data and the display rule instruction data are small in data size occupied space, so that operationprocesses of the wireless reception end and the processor are convenient.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a picture data processing device, a picture data processing method and electronic label display system components. Background technique [0002] The current electronic label display system, such as the supermarket electronic price label system, uses a wireless display screen, that is, each display screen is equipped with a wireless data receiving device, and the server and the display screen use wireless communication to display and replace pictures. Specifically, during the display process, the display screen decodes the encoded picture data received from the server, so as to display the picture. Among them, the display screen adopts a dot matrix display screen, and the displayed picture is a dot matrix image, also known as a pixel image or a bitmap, that is, a picture whose smallest unit is composed of pixels. , that is, each pixel has its own color information. When ...

AI Technical Summary

Problems solved by technology

When it is necessary to update multiple display screens at the same time, it will also increase the power consumption of the server to transmit wireless data and reduce the transmission speed of wireless data. In serious cases, the encoded data will be lost, resulting in wrong display on the display screen.
