Abstract

The invention provides an LED box. The LED box comprises a scanning card and a plurality of LED lamp panel modules connected to the scanning card, wherein the scanning card comprises an image display control chip; the image display control chip is used for receiving a data packet input from the outside and unpacking the data packet, carrying out classifying treatment on the data obtained after unpacking, carrying out image capturing (in a manner of corresponding to the size of a loading area of the scanning card), correcting treatment, gray level separation and data rearrangement on the image data obtained after classifying treatment, so that image display drive signals are generated, and carrying out grouping treatment on the image display drive signals so that at least one path (such as a plurality of paths) of grouped image display drive signals is output to the plurality of LED lamp panel modules. According to the LED box, the function of the scanning card is made chip-based to the greatest extent, and thus the purposes of reducing the size of the scanning card and improving the display effect of an LED display screen body are achieved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to an LED display screen control system. Background technique

[0002] With the development of technology and the progress of society, LED display screens are more and more widely used in daily life. The commonly used LED display screen control system mainly includes sequentially connected video sources, video processors, sending cards, scanning cards and LED display screens. The display screen, and the scanning card is generally installed in the LED box with the HUB board (also called the adapter board). At the same time, the HUB port on the HUB board will be connected to multiple LED light board modules for cascade display through cables or pins. In this way, an LED box is formed, and multiple LED boxes are spliced ​​into an LED display.

[0003] With the development of indoor small-pitch LED displays, more and more pixels need to be loaded by the scanning card. However, due to ...

Embodiment Construction

[0026] 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.

[0027]Specifically, the following embodiments of the present invention propose that the functions of the scanning card be chip-based as much as possible to solve the problems of signal transmission and HUB wiring in the existing LED display control system, and at the same time reduce the volume of the scanning card and support a larger load. , supports small-pitch screens, and even solves the signal stability and reliability problems in cascading and multi-stage transmission of existing scanning cards in signal processing, reduces EMI, and more efficiently meets customer EMC requirements.

[0028] see figure 1 , which is a schematic structural diagram of a scanning card according to an embodiment of the present invention. Such as fig...
