Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
The aviation display or instrument generally comprises 3 parts, namely a power panel, a graphic panel and a front-end liquid crystal display module. The power panel carries out filtering, anti-surge and power secondary conversion treatment on the airborne power supply; drawing various graphical interfaces or instrument panels by the graphic plate; the front-end liquid crystal display module mainly realizes the drive of liquid crystal display and backlight adjustment. With the development of technology, on-board avionics systems are increasingly demanding with respect to the size and power consumption of displays, and it is desirable that the size, thickness and power consumption of displays may be reduced. The conventional display control system comprises two major systems of a graphic generation controller and a liquid crystal module controller, and the two major systems are mutually independent and require two circuit boards, so that the thickness of display is difficult to reduce in structural design, and similarly, the circuit boards are increased, and the power consumption of the circuit system is difficult to reduce.
It can be seen that it is difficult to achieve a significant improvement in the thickness of the display structure based on the existing technology only by upgrading the technology of the electronic components, because the existence of the dual circuit board structure in the existing structure already determines the lower limit of the thickness thereof, and the technical barrier of the dual circuit board structure cannot be broken through, so that the structural thickness control and the running power consumption control of the aviation display cannot be broken through all the time. Based on the problems, the invention provides a novel aviation display control system, and the problems of large structure thickness and large operation power consumption of the display caused by double circuit boards are solved fundamentally. The graphic generation and display driving which can be realized by two circuit boards are integrated into one control circuit board, and the structural thickness and the operation power consumption of the display are greatly reduced on the premise of reducing the whole circuit board.

The controller can integrate the graphic board circuit of the traditional display with the driving circuit of the front-end liquid crystal display module, and can realize the functions of graphic drawing, liquid crystal display driving, backlight adjustment and the like by using one controller. Based on the running speed of ZYNQ, the display circuit control system provided by the invention is suitable for a display with small size (the resolution is lower than 1024 x 768 resolution) or large size and low requirement on the graph refreshing speed.

The ZYNQ series is the first scalable processing platform in the industry introduced by sailing corporation (Xilinx) to provide the required processing and computational performance levels for high-end embedded applications such as video surveillance, automotive driver assistance, and factory automation. The scheme of the invention utilizes the 'extensible' characteristic, and in a system architecture, the extensibility means that a mechanism and an element (hook) of the system are expanded/improved by a new function when the system is designed, and the system infrastructure is not required to be greatly modified. The good architecture reflects the design principle for achieving the aim, and a development blueprint is formulated for possible construction work in future. Based on the "extensible" feature, the scheme of the present invention constructs two parts, namely a soft core module and a logic module, in the control unit 10, for graphics generation and display driving, respectively, so that the two share a control circuit board.
