The present invention relates to an electronic signboard system consisting of a plurality of pixel panels, and more particularly to an electronic signboard system for inputting text or symbols in the form of a remote control and selecting and controlling effects.

Light Emitting Diode (LED) is a light emitting diode that emits light, and there are many kinds of colors and sizes such as red, green, blue, and white, but RED and GREEN colors are mainly used as light emitting devices of LED display panels. Due to the semi-permanent lifespan over time and low power consumption, the application range is being expanded to the state-of-the-art devices that will greatly contribute to the future advertising industry.

The LED display board using LED as the light emitting device implements a display board by arranging a plurality of LEDs in a tiled manner and lighting only a part of the LEDs, and at present, such LED display boards have a plurality of panelized pixel panels. (Pixel Pannel), the pixel panel is composed of a plurality of pixels arranged horizontally, vertically.

Such LED signboards are largely divided into a signboard system controlled by a computer and a signboard system controlled by a remote controller, as illustrated in FIG. 1 for describing a conventional LED signboard system.

The display board system controlled by the computer 1 as shown in FIG. 1 (a) controls the LED display board by predetermined software installed in the computer 1 in conjunction with the LED display board and the computer 1. At this time, all characters or symbols output through the LED display board are transmitted in a bitmap format file from the computer 1 to the LED display board. Therefore, as shown in the figure, the size of the desired picture, text, font, thickness, color and the like can be controlled in various ways to display the characters or symbols of various forms and positions, but the computer (1) Because it is controlled by the need for basic knowledge about computer operation, change of characters or symbols is cumbersome, and there is a problem that the space is limited in installing the LED sign. In addition, because of the need to have a computer, small micro-computers have a problem that the computer-controlled display system is relatively expensive.

Therefore, in order to solve the above problems, the user can easily change the letters or symbols, and are less subject to the spatial constraints of the installation, and the remote control as shown in FIG. 1 (b) is relatively inexpensive. An electric signboard system controlled by (2) has been developed.

The electric signboard system controlled by the remote controller 2 is provided with a key for inputting characters or symbols in a manner similar to the character input method of a mobile phone to the remote controller 2 to display characters or symbols desired by the user. You can enter

Therefore, the sign board system controlled by the remote controller 2 can freely change letters or symbols from the user's point of view, and the convenience thereof cannot be compared with the sign board system controlled by the computer, and the installation of the sign board is also free. .

However, the electric signboard system controlled by the remote controller 2 has a problem that only one stage can be implemented as shown in FIG. In other words, the signboard system controlled by the remote controller 2 implements the characters or symbols to be output by text codes, so that a character composed of Hangul vowels and consonants on a single pixel panel composed of 256 pixels of 16 × 16 Is expressed. That is, in the case of the six-column display panel as shown in FIG. 1 (b), the expression of 'Comtel Sign Long' is expressed in 'Com', 'Tel', 'Ca', 'In' and 'May' in each of six pixel panels. , To express 'tax'. Although FIG. 2 illustrates the limitations of the LED signboard system controlled by the conventional remote controller, the LED signboard system controlled by the conventional remote controller has a size of 8 × 16, 16 × 16, and 24 × characters or symbols to be output. 16, 32 × 16 and 40 × 16 variants are possible. However, this is a variation that increases only the width of the letter or symbol in the horizontal direction, so that when the size of the letter or symbol is severely increased, the size of the letter or symbol is asymmetrically distorted.

Therefore, if you want to express a letter larger or smaller in the display board or need to output in multiple stages, there is a problem that the control by the computer of FIG.

Although there is an electronic display system which is composed of 32 × 32 pixel panels and is controlled by a remote controller, it is only symmetrical because only the output size is increased, and thus only the width of characters or symbols is enlarged as described in FIG. As a result, it was not possible to increase or decrease the size of characters or symbols, or to output the data in multiple stages with a remote controller.

Therefore, the present invention was devised to solve the above problems and overcomes the limitation of the electric signboard system controlled by the conventional remote control, which cannot control the size conversion and position conversion of the conventional characters or symbols with the remote control, and is controlled by the conventional computer. It is an object of the present invention to provide a display system and a control method that can be controlled by a remote control various forms that are displayed only in the display system.

In addition, it is possible to enlarge or reduce the character size or select the position by simple operation using the remote control, and various forms of expression are possible. It can have the advantages of the signboard system controlled by the control panel and the signboard system controlled by the conventional computer at the same time, so that the same advertising effect can be expected at a relatively low cost compared to the computer controlled panel system.

A control signal outputting step of outputting a control signal through a corresponding output unit of the signboard driving microcontroller when the terminal to be output of letters or symbols is determined in the signage control command signal processing step; And In the control signal outputting step, a control signal output from the LED driver microcontroller is input to a driving module for driving each 16 × 16 pixel panel, and is supplied to the LED control command signal through a two-stage LED light emitting unit consisting of the 16 × 16 pixel panel. Character-to-symbol output step of expressing the character to the symbol according to the two-stage type light emitting diode control panel controlled by the remote control. The method of claim 4, wherein the magnitude conversion of the electronic control panel signal processing step is performed. A (A is 8, 16, 24, 32, 40, 48) × 16 size characters or symbols quantitatively enlarged to 2A × 32 size characters or symbols, and A2 size text code of 2 × 32 size A quantitative enlargement step of generating a text code; And 2A x 32 sized text code dividing step of dividing the 2A x 32 sized text code generated in the quantitative enlargement into an upper output part and a lower output part; Control method. The method of claim 4, wherein the magnitude conversion of the electronic control panel signal processing step is performed. Matches the basic text code and the enlarged text code by character or symbol, including the basic text code of 16 × 16 size character or symbol and the enlarged text code of 32 × 32 size character or symbol, and the basic 16 × 16 size standard when enlarged. And a text code replacing step of replacing a text code with an enlarged text code. 2.
