Embodiment Construction

[0024] 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.

[0025] figure 1 It is a structural schematic diagram of an LED display screen according to an embodiment of the present invention. Such as figure 1 As shown, the LED display screen 100 includes a plurality of LED boxes 10 spliced ​​together, for example figure 1 The six LED boxes shown in , and a single LED box 10 usually includes a plurality of LED light boards 13, for example figure 1 The four LED lamp panels 13 shown in. It should be noted here that the numbers of the above-mentioned LED boxes 10 and LED lamp panels 13 in the LED display screen 100 are only examples, and are not intended to limit the present invention.

[0026] Please also see figure 1 and figure 2 , figure 2 It is a schematic structural diagram of a single...

Abstract

The invention relates to an LED lamp panel, an LED box body and an LED display screen. The LED lamp panel comprises a circuit board, a first input / output interface formed in the circuit board, a plurality of LED pixels, a nonvolatile memory and a memory drive and control circuit, wherein the memory drive and control circuit comprises a driver and an enable controller; the driver is electrically connected with the first input / output interface and the nonvolatile memory; the enable controller is electrically connected with the first input / output interface and the driver. According to the LED lamp panel, the LED box body and the LED display screen, the memory is configured on the LED lamp panel to store correction data of the lamp panel, when a receiving card of the LED box body is required to be replaced, the correction data of the lamp panel, which is controlled by the receiving card, is not required to be written into a new receiving card by an additional computer because the new receiving card can directly read the correction data from the memory on the LED lamp panel; when the LED lamp panel is required to be replaced, the receiving card can directly read the correction data in the memory on a new LED lamp panel. Therefore, the receiving card and the LED lamp panel can be replaced rapidly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED lamp board, an LED box and an LED display screen. Background technique [0002] In the existing LED (Light Emitting Diode, light-emitting diode) display control system, the LED display is usually spliced ​​by multiple LED cabinets, and each LED cabinet includes a receiving card (or LED display control board) and a plurality of LED light boards electrically connected to the receiving card, and the LED cabinet of some LED displays will also be equipped with an adapter board (or Hub card) to connect multiple LED light boards to the receiving card. [0003] In the prior art, since the memory for storing pixel correction coefficients is set on the receiving card, when the receiving card needs to be replaced with a new one after the receiving card is broken, it is necessary to renew each LED box on which the receiving card is located through an additional computer. The pixel c...
