Bistable liquid crystal display having a remote display update control

A method of displaying information by a liquid crystal display comprising:

• coupling a cholesteric liquid crystal display to a signal input to provide a display device;
• providing a hand-held user device remote from the display device for controlling the cholesteric liquid crystal display, the hand-held user device having:
• a signal output coupled to a driver control, and
• keypad user input coupled to the driver control, the driver control providing matrix addressing signals in response to the user input being controlled by a user to display the information by the cholesteric liquid crystal display;
• and
• electrically interconnecting the display device with the hand-held user device for providing the matrix addressing signals to the cholesteric crystal display by coupling the signal output to the signal input through a signal interface.

A liquid crystal display apparatus comprising:

• a cholesteric liquid crystal display coupled to a signal input to provide a display device;
• a hand-held user device remote from the display device for controlling the cholesteric liquid crystal display, the hand-held user device having:
• a signal output coupled to a driver control, and
• a keypad user input coupled to the driver control, the driver control providing matrix addressing signals in response to the user input being controlled by a user to display the information by the cholesteric liquid crystal display, the display device being electrically interconnected with the hand-held user device for providing the matrix addressing signals to the cholesteric crystal display by coupling the signal output to the signal input through a signal interface.

A method of displaying information by a liquid crystal display comprising:

• mounting a display rail to a product shelf, the display rail being adapted for removably mounting thereon a bistable liquid crystal display;
• mounting a display controller to the product shelf, the display controller being responsive to a user input controlled by a user to display information by the bistable liquid crystal display;
• and
• electrically interconnecting the display controller to the display rail to provide display control information to the bistable liquid crystal display.

A method of displaying information by a plurality of liquid crystal displays comprising:

• mounting a plurality of display rails to a product shelf, each display rail being adapted for removably mounting thereon a one or more bistable liquid crystal displays;
• mounting a display controller to the product shelf, the display controller being responsive to a user input controlled by a user to display information by the bistable liquid crystal displays;
• and
• electrically interconnecting the display controller to each display rail through one or more display rail electrical interconnectors to provide display control information to each bistable liquid crystal display.
