Problems solved by technology

But this design has fatal disadvantages: complex circuit, low hardware utilization, and huge cost
[0006] However, the main defect of this scanning LED display device 33 is: since all LEDs are scanned in a row, and each row of LEDs is sequentially lit at intervals, the LEDs in each pixel are lit at intervals.
Moreover, the longer the interval, the worse the stimulation to human eyes, resulting in a decrease in the stability of the display screen, resulting in a decrease in visual stability
In order to shorten the interval, an effective measure is to increase the scanning frequency of the scanning LED display device 33, but the improvement of the scanning frequency will also cause the circuit for driving and controlling the pixel 33 to be more complicated, and the excessively high scanning frequency will increase The noise of the circuit, which in turn will affect the normal operation of the circuit, thereby reducing the effect of the display

Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] The scanning LED display unit in the embodiment of the present invention is mainly used to receive and display information such as images and texts transmitted by various peripheral devices (such as computers, players, etc.), but it is not limited thereto.

[0049] like figure 1 As shown, in the first embodiment of the present invention, the LED display unit 10 mainly includes a control device 11 , a driving device 12 and a display module 13 .

[0050] The control device 11 is mainly used to generate the switch control signal Hsel and the suction flow control signal Rs to respectively control and drive the switch device 121 and the flow suction device 122, so as to sequentially light up the LEDs of the same group synchronously, such as figure 1 , figure 2 and image 3 shown. In this embodiment, the control device 11 includes an MCU, such as Motorola's MC6...

Abstract

The present invention provides a scanning LED display unit, including a display module including multiple pixels; a control module for output a switch output control signal and a suction current control signal; a driving module for receiving a working voltage, the switching control signal and the suction current control signal. Each pixel is composed of at least two group LED, anode of each LED is loaded with working voltage in turns, and cathode of same group LED processes suction current at the same time, LED of the different group are lighted in turns. LED of the different group is lighted in turns, this improves visual stablility. In addition, the invention also relates to a display method of scanning LED displaying unit.

Description

【Technical field】 [0001] The invention relates to an LED display system, in particular to a scanning LED display unit. At the same time, the invention also relates to a display method of the scanning LED display unit. 【Background technique】 [0002] At present, LED display devices can generally be classified into static and scanning according to display control methods. Static display means that each LED in the LED electronic display is controlled individually by hardware, and all the LEDs in the entire LED display are controlled at the same time. The biggest advantage of this method is that the program design is simple and the screen does not flicker. But there are fatal shortcomings in this design: complex circuit, low hardware utilization, and huge cost. [0003] With the advancement of LED manufacturing technology, the brightness of LED has been significantly improved. At present, more and more LED display screens use dynamic scanning to realize display. [0004] lik...
