Single-board integrated LED (light-emitting diode) dot-matrix module

Abstract

The invention provides a single-board integrated LED (light-emitting diode) dot-matrix module which comprises a circuit board and a dot-matrix circuit which is at least a 16*15 single primary color SMD (surface mounted device) LED dot-matrix circuit, wherein the dot-matrix circuit is arranged on a main view face of the circuit board and used for displaying information, a control circuit and a power interface are arranged on a rear view face of the circuit board, the control circuit is respectively connected with the power interface and the dot-matrix circuit, the power interface is used for connecting a power supply used for supporting the operation of the control circuit and the dot-matrix circuit, the control circuit is used for controlling LEDs in the dot-matrix circuit to display the information according to requirements of edited or modified display contents according to operation data received or typed by the control circuit. According to the invention, through the control circuit and the power interface which are arranged on the module, the problem that a module in the prior art needs an additional editor and an additional display controller can be solved, therefore, the use condition of the LED dot-matrix module is simplified effectively, and the module can display information and the displayed contents can be edited and modified by virtue of an infrared remote controller or operational keys after the power interface is connected to the power supply.

Description

technical field [0001] The invention relates to an LED dot matrix module, in particular to a structure of a single-board integrated LED dot matrix module with at least a 16x15 single primary color patch LED dot matrix circuit. Background technique [0002] At present, various LED dot matrix modules on the market, commonly used are 8x5, 16x15 and 16x16, etc.; 16x15 means a module with 16 rows by 15 columns of dot matrix circuits, and a single primary color 16x15 LED dot matrix module, there are 16x15x1=240 pieces LED; 16x15 dual-color LED matrix module, with 16x15x2=480 LEDs; 16x15 tri-color LED matrix module, with 16x15x3=720 LEDs. For example, Chinese patent application number 200920107214.3, Chinese patent authorization announcement number CN201383298, authorization announcement date January 13, 2010, application date 2009.04.17, utility model disclosure "an LED dot matrix module" There are many similar literature reports. The LED dot matrix module structure of above-ment...

Problems solved by technology

The LED dot matrix module structure of above-mentioned prior art, as Figure 8 , Figure 9 The shown 16x15 red and green dual primary color LED dot matrix module includes circuit board 1 and the 16x15 red and green dual primary color LED dot matrix circuit 2 on the main viewing surface 1A of the circuit board 1, and the circuit board 1 rear viewing surface 1B. The set row drive connection points X1 to X16, the green LED column drive connection points yy1 to yy15 and the red LED column drive connection points Y1 to Y15; Figure 10 As shown, the LED dot matrix module of the prior art only includes the LED dot matrix circuit 2. Everyone is familiar with the advantages of the LED dot matrix module of the prior art; Modules generally cannot edit, modify and display information alone. After assembling multiple modules, they must be equipped with a display information editing machine or a PC with software provided by the manufacturer, a display controller, a DC stabilized power supply, and related software. Only the LED dot matrix module can display information and can edit and modify the display content of the LED dot matrix module, which is inconvenient and flexible to use

That is to say: the LED dot matrix module of the prior art cannot be used alone, let alone edit and modify the displayed content
