Embodiment 1

[0025] Such as figure 1 As shown, this embodiment provides an LED display control system, and the LED display control system includes a host computer, a control device and two or more LED modules.

[0026] The host computer can be a personal computer, which is used to send video signals, such as video signals of various texts, graphics, letters, animations, etc.

[0027] The control device is connected with the host computer for receiving video signals sent from the host computer, and processing each video signal, for example, by setting various processing programs, according to the video signal, generating the first 1. display data, and send it to each LED module, so that each LED module can display the image, text, letter, animation and so on of the video signal.

[0028] Each LED module is provided with a plurality of LED units; each LED unit includes one or more LED light-emitting diodes, and each LED light-emitting diode can be one of red LED light-emitting diodes, green...

Embodiment 2

[0043] Such as figure 2 As shown, on the basis of the above examples, the LED display control system is also provided with an adjustment device, which is used to generate adjustment data according to the performance parameters of LED light-emitting diodes of various colors; for example, the adjustment device sets An input interface, through which the performance parameters of each LED light-emitting diode are input, wherein the performance parameters can be the brightness, wavelength, color coordinates, etc. of each LED light-emitting diode, and the adjustment device correspondingly produces each Adjustment data for LED light-emitting diodes. The adjustment device can be directly connected with each LED module, and send the adjustment data to each LED module, correspondingly adjust the brightness of each color LED light-emitting diode in each LED module, so that the luminous color gamut of each LED module is the same.

[0044] The performance parameter information of each LE...

Embodiment 3

[0050] Such as image 3 As shown, on the basis of the above examples, the adjustment device may also be connected to the control device, the adjustment device generates adjustment data, and sends the adjustment data to the control device, and the control device A first control module and a second control module are set, the first control module is used to receive the video signal, and generate second display data according to the video signal, and send it to the second control module; The second control module receives the adjustment data from the adjustment device, and, according to the adjustment data, converts the second display data into the first display data, and sends it to each LED module, and directly through the control device Regulate each LED light-emitting diode, so that each LED module displays graphics, text, letters, animations, etc. in the video signal in the adjusted color rendering area according to the first display data, and the light emission of each LED ...

Abstract

The invention discloses a display control system, which comprises a host computer, a control device and at least two LED modules, wherein either LED module is provided with a plurality of LED units; each LED unit is provided with at least one LED of at least one color; the LED units of LED modules are distributed in the same way; each LED unit in each LED module is provided with the LEDs of various colors in the same number; the LEDs of the same color are of the same sorting grade and a neighboring sorting grade; the control device is respectively connected with the host computer and LED modules for receiving video signals sent by the host computer; and first display data is generated according to a video signal and is sent to each LED module. The display control system has uniform display and a good display control effect.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED display control system. Background technique [0002] In the prior art, due to the influence of various conditions during the production process of each LED lamp, there will inevitably be differences. [0003] Since different customers have different requirements for the accuracy of each LED lamp, and the usage of each LED lamp is also different, therefore, the general lamp screen or display screen manufacturer, after receiving the order from the customer, then produces LED lamps. Manufacturers purchase LED lights. Since LED lights are relatively unstable during storage, they are prone to damage due to vibration, collision, etc. Therefore, LED light manufacturers will not store a large amount of goods in production, and it is difficult for light screen or display manufacturers to buy the same precision. Therefore, manufacturers of lamp screens or display screens generally buy LE...
