Abstract

The invention discloses a virtual button display operation method and device, comprising an input device, a virtual button logic processing module, a display interface module, a man-machine interface module, and a display device. The virtual button logic processing module is used to process the input signal sent by the man-machine interface module, generate different image signals corresponding to the pressed or released states of the virtual button, and send the generated image signal to Display the interface module, and then send it to the display device, so that the display device displays the screen corresponding to the virtual key; when the virtual key is in the selected and unselected states, two different screens are displayed, so that the user can clearly determine the virtual key state and generate corresponding control signals. The disclosed virtual button display operation method and device do not include complex software and hardware such as CPU and operating system during operation, and have the advantages of simple system, easy to be fully tested and verified, and resistant to threats brought by viruses and Trojan horses.

Description

technical field [0001] The present invention relates to the field of display and operation of virtual keys, in particular to a display and operation device for virtual keys that uses hardware description language to realize the display and operation functions of virtual keys, and also relates to a device that uses hardware description language to realize the display and operation functions of virtual keys The display operation method of the virtual key. Background technique [0002] Virtual buttons are relative to physical hard buttons that exist physically. A virtual button refers to a virtual button image (namely called a virtual button) that appears on a screen of a display device and simulates a physical button through software. The virtual button image area is not a physical physical button, but it can be operated by devices such as a mouse or a trackball, and different functions can be performed according to the operation image displayed on the screen of the operating...
