A display circuit, and associated method, including a high-persistence display element, such as a liquid crystal display device, which visually displays sequences of informational image frames while minimizing interference between successive ones of the frames. A sequence of informational image frames are displayed upon the display element, thereby to generate a visual signal which appears to scroll across the display element. Blank image frames are interspersed between successive ones of the informational image frames to reduce thereby interference between successive ones of the informational image frames.

High-persistence display circuit and method to therefor

A radio communication device menu system includes a memory (232) storing menu items. A controller (220) is coupled to the memory. A user controlled input (106) is coupled to the controller for manually inputting control signals to the controller. A display (108) is also coupled to controller to display signals from the controller. The memory includes a short menu and an extended menu. The controller is responsive to a predetermined actuation pattern of the user controlled input to select one of the extended and short menus as the active menu, and for scrolling through the selected one of the short and the extended menus. According to another aspect of the device, the user controlled input includes a clear key which is held for a first predetermined time period to return to a higher level in the active menu and the clear key is held for a second predetermined time period to exit the active menu.
