Description

LED Dimmer Soft Dimmer

The present invention relates to an electronic board using a light emitting diode (hereinafter referred to as an LED).

In various businesses and public offices, it is common to publicize notices and publicity notices on blackboards, posters, or franc cards.

Therefore, real estate and public notices that require a lot of posts, such as public notices are created by making a poster directly or printed and attached to a printer, so that civil complaints and consumers to recognize. However, if you use this method, notices and promotions are difficult to see at night, and the content is not well understood even in the daytime. In addition, there is an inconvenience to print and post one by one.

Therefore, the related industry develops and presents various display boards, but it is still too much burden to install in public offices and businesses at high price to apply existing Pixel and LDM MODUL to display boards.

For this reason, the launch of cheap and effective LED signboards is required.

The present invention is a DSP (Digital Signal Processor) part that is displayed on the LED display board for the purpose of providing a display board of the LED (light emitting diode or less LED) more effective display method for the display of various LED display boards and information. Independent system greatly improves the speed of expression.Applies smooth image with light dimmer and soft dimmer, and red, green, and blue (4096 ~ 32768 true color) circuit. Provides an electronic sign.

The purpose of the present invention is to provide a LED display panel using hardware to revive the demands of the industry and to provide more effective display effects. The basic concept of hardware is to code the input signal at the remote control receiver to complete the entire operating program and display sequence system. The MPU part that manages and the DSP (Digital Signal Processor) part that display the display data on the LED board greatly improve the expression speed.

The LED is slowly turned on and flickered with a soft dimmer function to apply a soft image, and red, green, and blue (4096 ~ 32768 true color) circuits are applied to realize a wide range of colors.

The character input function of the conventional remote control display board has a complicated and difficult problem because it is not possible to see the movement of the animation in real time when inputting complex characters and animations, and the special characters and animation input methods are numerical or special symbol setting concepts. By using specific key of remote controller and PC, accuracy and convenience of input are secured.

The conventional hardware concept is that the MPU must process the input signal processing, the entire operating program, and the display on the light emitting diode display at the remote control receiver, so that the progress speed decreases and the display sticking phenomenon often occurs.

In the present invention, the MPU part that manages the program and display sequence system and the DSP (Digital Signal Processor) part that display the display data on the LED display board greatly improve the expression speed.

1 is a text and animation input structure

2 is the overall structure of LED sign control

3 is a remote control elevation view

4 is a schematic diagram

In order to achieve the above object, the present disclosure provides an LED display panel composed of an indicator, a controller, and a display.

The display unit may configure a module in which 16 LEDs are arranged in horizontally and vertically so that Hangul / English can be output, and the modules may be configured in series.

The control unit 20 includes a display patch part 27 for driving the module and a DSP control switching part 24 for controlling the driving part.

The indicator unit may include a remote controller including an infrared sensor in a wireless case, and a reception sensor to which a signal from the infrared sensor is applied, and in the case of a wired connection, a PC may be connected to the system hardware unit.

Best Mode for Carrying Out the Invention The most preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

When the infrared remote control unit 13 transmits a signal corresponding to each button, the remote control receiver 14 receives the signal, amplifies the signal, reads it into the MPU 21 input port, codes the signal, and inputs and edits the character corresponding to the code. Run the function setup program. The character input and various function setting data generated here are stored in the RAM 22 memory and the EEPROM 23 memory for permanent storage and graphic fonts. And RAM (22) stores the graphic and character fonts corresponding to the address table values of the graphic and character fonts stored in the EEPROM (23) memory in the input character and symbol code values to express the current running status on the electronic board. Store in memory. Only execution up to this point (system hardware) is governed.

It is a DSP (Digital Signa Processor) part that is displayed on the electronic board, and it is an independent system that can greatly improve the speed of expression.The LED is gradually turned on and softly applied by the soft dimmer function and red, green, and blue ( 4096 ~ 32768 true color) circuit can be applied to realize a wide range of colors.

The character input operation of the complicated and difficult remote control signboard is secured by using the remote controller and the specific key of the PC.
