Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is a schematic structural diagram of an LED display system according to an embodiment of the present invention. like figure 1 As shown, the LED display system 10 includes an LED display control card 11 , a plurality of LED light panel strings 13 , and a plurality of terminal modules 17 . Wherein, a single LED lamp panel string 13 includes, for example, two LED lamp panel 15 a, 15 b and is cascaded to the LED display control card 11 , and each LED lamp panel string 13 is configured with an end terminal module 17 . It should be noted that the LED lamp panels 15a and 15b may have the same circuit structure, and the difference in labels is mainly used to indicate that they are in different positions in the LED lamp pan...

Abstract

The invention relates to an LED (Light Emitting Diode) display screen system, which comprises a control card of an LED display screen, an LED lamp panel string and a tail-end terminating module, wherein the LED lamp panel string comprises an LED lamp panel, and is electrically connected to the control card of the LED display screen, or a plurality of LED lamp panels are connected to the control card of the LED display screen in parallel so as to receive data and a control signal, which are output by the control card of the LED display screen; the tail-end terminating module is electrically connected to the last primary LED lamp panel in the LED lamp panel string, so that a return data signal output by the last primary LED lamp panel is transmitted to the control card of the LED display screen through the tail-end terminating module and the LED lamp panel string in sequence. According to the invention, a data return path section is formed on the LED lamp panel, so that fault detection of each LED lamp panel of the LED display screen can be completed without additionally providing a monitor wafer building loop, thus wiring is simplified, and the LED display screen system has lower cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED display screen system. Background technique [0002] As a new type of display technology, LED (Light emitting diode) display system has gradually been accepted by the market due to its advantages of energy saving, environmental protection, and high brightness, and has been widely used in urban media, urban transportation and other fields. [0003] Among them, the LED display system in the traffic field is generally used to display information such as road names, traffic conditions, and speed limits. Every LED on the LED display may fail. When the number and location of LED failures reach a certain level, it will It will affect the display of information, and in severe cases, it will convey wrong information. Therefore, how to enable the LED display system in the traffic field to detect LED faults in time is one of the problems to be solved urgently. [0004] The LED fau...
