Problems solved by technology

[0003] 1) You need to use a computer instead of an NFC mobile phone to read and rewrite, which is inconvenient and inflexible;
[0004] 2) Wired programming and rewriting, the rewriting efficiency is low;
[0005] 3) It needs to be equipped with a fixed burning device, which is connected to the computer and the display device, and the special software on the computer edits the content (text or pattern), and finally writes it to the storage space of the display device. This operation is cumbersome and extremely complicated;
[0006] 4) The reuse rate is low, because it is difficult to rewrite, so people often have no desire to rewrite;
[0007] 5) Non-passive technology, not energy-saving and environmentally friendly

Embodiment Construction

[0034] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0035] see figure 1 , the present invention utilizes NFC technology to rewrite the method for display device display content, comprises the following steps:

[0036] Step S1, the user inputs characters or graphics, and selects different font files to form a dot matrix code; the specific steps of this step are step S11, the user inputs characters or graphics; step S12, selects different font files, and if graphics are selected, use The graphics are divided into 32*32 matrix in the form of graphic separation, and the matrix is ​​composed of hexadecimal numbers one by one in the "column mode", and the dot matrix code is composed of two-byte hexadecimal numbers to represent a column of dot matrix distribution; if text is selected, then Query the font file according to the character location code to find the correspon...

Abstract

The invention discloses a system and a method for revising display content of a display device by the NFC technology. The system comprises an NFC chip, the display device and an NFC portable device. The display device comprises a master MCU (microcontroller unit) and a display screen. The NFC portable device is connected with a non-contact interface of the NFC chip for data transmission. The master MCU chip is connected with a read-write interface of the NFC chip and reads a dot matrix code of the NFC chip or writes data into the NFC chip. The display screen is connected with the master MCU chip for content displaying. The NFC chip is used as a bridge, the bridge allows data transmission for the display device and displaying of preceding data of the display device to be greatly simplified, and the operating process is convenient and simple. The system and the method have the advantages that revising can be performed just with a special APP (application) in the NFC portable device, revising is facilitated, and convenient revising leads to high reuse rate and environment friendliness of the NFC portable device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a system and method for rewriting display content of a display device by using NFC technology. Background technique [0002] At present, LED rocking sticks, LED display screens, LED rotating lights, etc. are mainly used as display devices. These display devices mainly use computer online programming to rewrite the content to be displayed in the storage device to rewrite the display results. This rewriting technique has the following disadvantages: [0003] 1) You need to use a computer instead of an NFC mobile phone to read and rewrite, which is inconvenient and inflexible; [0004] 2) Wired programming and rewriting, the rewriting efficiency is low; [0005] 3) It needs to be equipped with a fixed burning device, which is connected to the computer and the display device, and the special software on the computer edits the content (text or pattern), and finally writes it to the...
