Embodiment Construction

[0016] 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.

[0017] figure 1 It is a schematic structural diagram of an LED display system according to an embodiment of the present invention. Such as figure 1 As shown, the LED display system 10 includes an LED display control card 11 and a plurality of LED lamp board strings electrically connected to the LED display control card 11 . Wherein, a single LED lamp panel string includes cascaded LED lamp panels 13a, 13b, for example. It should be noted that the LED light boards 13a and 13b may have the same circuit structure, and the different labels are mainly used to indicate that they are in different positions in the LED light board string; in addition, the number of LED light board strings is not limited to figure 1 The two shown depend on th...

Abstract

The invention relates to an LED light panel and an LED display screen system adopting the same. The LED light panel comprises a plurality of LEDs, a first input and output interface, a second input and output interface, an LED drive circuit, a data feedback circuit and a terminating circuit. The LED drive circuit is electrically connected with the first input and output interface and used for driving and controlling the LEDs; the data feedback circuit is electrically connected with the first input and output interface and the second input and output interface; and the terminating circuit is electrically connected with the LED drive circuit, the data feedback circuit and the second input and output interface and used for selectively connecting the LED drive circuit with the second input and output interface or connecting the LED drive circuit with the data feedback circuit according to the connection status of the second input and output interface. As the data feedback circuit and the terminating circuit are arranged on the LED light panel, the fault of each LED light panel of an LED display screen can be detected without additionally arranging a monitoring board construction loop, consequently, wiring can be simplified, and the cost is low.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED lamp panel and 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....
