Abstract

The present invention provides an electronic tag display system and an electronic tag display method. The display system comprises a server and at least one set of electronic tag display system components; each set of the electronic label tag system components comprises a picture data processing apparatus and at least one dot matrix display; the server is used for sending a wireless data signal, and the wireless data signal is a display rule instruction list and character data; the picture data processing apparatus is used for receiving the wireless data signal, calling display rule instructions in the display rule instruction list to generate the character data into bitmap data, and sending the bitmap data to the wired connected dot matrix display; and the dot matrix display is used for displaying the dot matrix picture data. Since the space occupied by the data amount of the character data and the display rule instruction data is small, when the server carried out wireless signal transmission, the wireless signal can be quickly and accurately transmitted to the picture processing apparatus.

Description

technical field [0001] The invention relates to the field of image display, in particular to an electronic label display system and an electronic label display method. 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 updating or modifying the displayed picture, the ser...
