Due to the low power consumption and low power consumption, it is greatly contributing to the advertising industry of billboards. For example, a large number of LEDs are arranged in a tiled manner so that only some of the LEDs are lit to implement a small-sized electronic display board.

The LED display panel is panelized, and each pixel panel is composed of pixels arranged horizontally and vertically. By connecting the pixel panel in the horizontal direction as many times as desired, one stage LED display board can be used. The LED display board is composed of a combination of one or more square pixel panels, each pixel panel is a combination of pixels arranged by a × a, and each pixel of the LED of different colors constituting the pixel Is made in combination.

For example, the pixel panel is a square and consists of 16 horizontally 16 vertically, or 256 LED DOTs, and a letter composed of a Korean vowel and a consonant is represented by one letter. Use to make. The size of the module also varies from 64 mm to 1000 mm depending on the application, but one module is composed of 256 dots and one Korean character is represented regardless of size. That is, 8 characters of Korean characters may be expressed at one time in the eight vertically arranged electronic display boards, and 16 characters in total of eight characters may be represented in the lower eight characters at the top.

Meanwhile, the conventional LED display board is divided into a remote control type and a personal computer connection type according to a data transmission / reception method, and the remote control type is a method of continuously and repeatedly displaying information stored in a memory (ROM), and a personal computer.
