Embodiment Construction

[0030] 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. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected t...

Abstract

The invention relates to a display control device. The main control core board and the sub-control core board in the display control device can be detachably plugged into the main control interface board or the sub-control interface board, so that debugging is convenient, and when a fault occurs, the Locate the fault location. Since the main control core board is plugged to the main control interface board through the first plug-in component, and the sub-control core board is plugged to the sub-control interface board through the second plug-in component, the hardware structure of the main control core board and the sub-control core board is the same , and the structure of the first plug-in assembly and the second plug-in assembly is also the same, so the main control core board and the sub-control core board can be used interchangeably. When the main control interface board or the sub-control interface board is damaged, the main control core board Or the sub-control core board can still be retained, avoiding the problem that the entire board cannot be used due to damage to the interface board, and reducing maintenance costs.

Description

technical field [0001] The invention relates to the field of display control, in particular to a display control device. Background technique [0002] With the advancement of technology, the display specifications of LCD (Liquid Crystal Display, Liquid Crystal Display) display devices are gradually increasing. In the display control device, the video processor is usually the main controller, and the video processor is connected to multiple sub-controllers, and the sub-controllers are used to control multiple cascaded light strips for display. Both the main controller and sub-controllers include FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array), SDRAM (synchronous dynamic random-access memory, synchronous dynamic random access memory) and network card chips, etc. High core chips also include interface boards with low integration, low cost, and simple soldering. Usually, the core chip is directly soldered on the interface board. If the interface boar...
