Description

LED adapter plate and LED display screen using same

[ field of technology ]

The utility model relates to the technical field of LED display screens, in particular to an LED adapter plate and an LED display screen using the same.

[ background Art ]

With the development and maturity of the LED technology, the LED display screen is more and more widely applied to various fields of social life due to high brightness, low power consumption and stable performance. The display requirements of users on the LED display screen are also higher and higher, no matter how the display effect of the LED display screen is gorgeous, once an unstable factor appears in a control link, the image of the whole display screen is greatly discounted in the mind of people. However, because the usage environments and conditions of the LED display screen are different, sometimes even bad, and there is always a link failure time, it is very important to have a backup system to ensure the normal operation of the LED display screen.

LED displays typically include an LED system card, a power module, and several LED unit boards that are assembled together.

The backup of existing LED display screens typically employs two sets of system cards, each including an LED receiving card for transmitting video signals to the LED unit board. However, in many application places, especially outdoor places, the size of the LED display screen is very large, the number of LED unit boards used is large, each LED receiving card can only provide video data for 4-8 LED unit boards, and the backup mode of two groups of system cards is easy to lead to complex wiring on site.

If a special system card is adopted, the processing and material preparation period is long, the early investment is overlarge, and the cost is not easy to withdraw. For example, CN209625761U discloses a dual-system backup circuit for a novel LED display screen system, which is respectively disposed on a main adapter plate and a secondary adapter plate, and includes a working state detection circuit, a working state judgment circuit and a data output control circuit; by detecting the working states of the two system cards and judging whether the two control cards work simultaneously at the same time, under normal conditions, only one system card works normally, the other system card does not work, and when the system card is abnormal, the other system card is switched to work. The patent uses two adapter plates for backup, and has high cost.

Therefore, it is necessary to provide a new LED adapter plate and an LED display screen using the same to solve the above technical problems.
