Embodiment Construction

[0012] The following describes the technical content in a non-restrictive manner in conjunction with the accompanying drawings, in order to help the public better understand the technology.

[0013] Such as figure 1 As shown, the LED display module with memory function of the present invention includes a receiving card, an adapter board and several display modules, each display module includes an ARM chip and a SPI-FLASH chip, The SPI-FLASH chip is located on the display module, and the ARM chip is placed on the adapter board. The ARM chip of each display module is connected to the SPI-FLASH chip through a 4-wire standard SPI interface, and each ARM chip is connected through a single wire. Communicate with the receiving card. The receiving card is an I5A-905 receiving card. The 52~59pins of the J2 interface of the 5A-905 receiving card are the display module communication lines DATA1~DATA8. These 8pins cannot be used as display signal lines. , DATA1~DATA8 are routed from J2 o...

Abstract

The invention provides an LED (Light Emitting Diode) display screen module with a memory function. The LED display screen module with the memory function comprises a receiving card, an adapting plate and a plurality of display screen modules; every display screen module comprises an ARM chip and an SPI-FLASH chip; the SPI-FLASH chips are arranged on the display screen modules; the ARM chips are arranged on the adapting plate; the ARM chip and the SPI-FLASH chip of every display screen module are connected through a four-line standard SPI interface; every ARM chip and the receiving card are in communication through one single line. The LED display screen module with the memory function solves the problem of tedious steps due to the fact that a traditional LED large screen replacement module or replacement control system has to again recalibrate a color coefficient and set a module pixel sequence and has the advantages of allowing plug and play, not needing once more debugging after delivery, enabling user flexible utilization to be facilitated and saving after costs.

Description

technical field [0001] The invention relates to a polarizing plate for vehicles, which is used for LED display unit modules to memorize their own pixel color attributes and pixel sequences. LED display field. Background technique [0002] The LED display module is one of the main components of the finished LED display. It is mainly composed of LED lights, PCB circuit boards, driver ICs, resistors, capacitors and plastic kits. The color correction data and pixel order of traditional LED large-screen modules can only be stored in the control system of the LED display scanning board (control system). When replacing or moving to other modules, the color data must be re-calibrated, such as changing different specifications or pixel order The module must reset the pixel order to display the image normally. Contents of the invention [0003] The present invention aims at the problems existing in the current LED display module, and provides a new LED display module with memory f...
