Problems solved by technology

It is necessary to design a sending card, which increases the difficulty of hardware design
In addition, many asynchronous controllers currently on the market cannot support two display screens at the same time, and the chip that can support two screen display at the same time is more expensive

[0025] see figure 1 , which is a schematic structural diagram of an asynchronous controller 100 provided in the first embodiment of the present invention. Such as figure 1 As shown, the asynchronous controller 100 includes: a display buffer 110 , an embedded processor 120 and a physical layer transceiver chip 130 .

[0026] Based on the above, the display buffer 110 is, for example, a DDR3 memory chip for storing display data. Of course, it can be understood that the display buffer 110 is not limited to using DDR3 memory chips, and other volatile memories can also be used.

[0027] The embedded processor 120, as the main control module of the asynchronous controller 100, is the main control core of the entire system operation. After being powered on, the embedded processor 120 runs an operating system such as the Android operating system and related application software to control various external devices to function. The embedded processor 120 includes a first output inter...

Abstract

The embodiment of the invention discloses an asynchronous controller and an LED display system. The asynchronous controller includes: a display cache; an embedded processor that is connected with thedisplay cache; and a physical layer transceiver chip which is connected with the first output interface of the embedded processor; wherein the embedded processor is used for carrying out screen capture processing on the display data in the display cache to obtain target display data, packaging the target display data according to a network protocol and outputting the packaged target display data to the physical layer transceiver chip through the first output interface. The embodiment of the invention can save the hardware design cost and reduce the hardware design difficulty.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an asynchronous controller and an LED display system. Background technique [0002] In the low-end small screen market such as light pole screens, advertising machines, etc., the LED (Light Emitting Diode, light emitting diode) asynchronous controller has a small load area, which can be satisfied by a Gigabit Ethernet port; at the same time, it is very sensitive to price. Most of the existing LED asynchronous controllers adopt the form of ARM+FPGA, and ARM is used as the main control card for functions such as control and playback. As the sending card, FPGA is used to connect the main control card and the receiving card, and is the control command and display data channel between the main control card and the receiving card. This architecture is relatively mature, but there are obvious shortcomings, that is, the cooperation of the sending card is required. This solution increa...
