The present invention relates to an LED display device, which is widely used for information boards, promotional texts, display boards, etc., to easily and quickly change the display contents by using a commercialized smart phone, so that the use of the LED display device can be more easily and widely used. will be.

Due to the generalization of the technology of LED display devices and a drop in LED component costs, LED display devices are being widely used for promotional purposes and information boards.

Even in small offices such as restaurants, pharmacies and hospitals, the environment is diversified for promotional purposes. Most of these promotional LED indicators use a fixed promotional text according to the demand of the consumer when selling. In recent years, some expensive LED indicators are equipped with a network function so that the promotional text can be changed according to the user's request from a remote server at a certain service cost, or a separate expensive remote controller can be purchased to edit some of the indicator contents on the remote controller. There is something you can do.

In general, the operation method of the LED display is to store the contents to be displayed in advance in the nonvolatile memory, and read out the memory from the control unit to display the LED indicator through the LED drive logic.

In this case, the LED indicator should be a combination of 16 x 16 LEDs in Korean characters per letter, and a letter is formed in English.

Therefore, in order to display several letters at the same time, it is possible to have several LED combinations of the 16x16 blocks listed above.

The way the letters are formed on the LED indicators is usually formed by scanning the same data several times a second with the scanline method. In other words, drive the horizontal lines one by one to read and input the data to be scattered on the vertical line from the memory, and then drive the next horizontal line to read the corresponding data from the memory and input the same line several times a second By inputting a letter image is formed on the LED.

The non-volatile promotional image storage memory was previously fixed at the time of purchase for the first time and it was difficult for the user to change the promotional contents. We edited the characters to be displayed on the computer and input them into the memory using a nonvolatile memory program device. If you want to change the promotional content during use, you can change it through the above series of steps.

Recently, remote control products have been introduced. When the contents of the LED indicator are edited and transmitted to a device such as a home infrared remote controller, the display contents of the LED indicator can be changed.

The present invention has been drawn under the above-mentioned background. Recently, a remote controller product that has been introduced requires the purchase of an expensive remote controller, and the editing function is limited to a simple text input level. In order to overcome this problem, it is possible to change the type of characters displayed on the LED display device indefinitely using the display function of the smart phone or web pad, the editing function using the touch pad, and the Bluetooth wireless transmission function. It can be simulated so that it can be demonstrated at, and the purpose is to make it easy to use the LED display for more various purposes without the burden of additional expensive remote control.
