FIELD OF THE INVENTION

The present invention relates to display apparatus.

BACKGROUND INFORMATION

Display apparatuses are used in a wide range of devices, such as portable devices, such as mobile telephones and tablet computer devices. The challenges for the designers of portable devices is to design a display apparatus that is light, battery efficient and convenient to use.

SUMMARY OF THE INVENTION

The present invention provides display apparatus comprising a plurality of display units each hingedly linked together to form a foldable display structure, each display unit comprising a display screen with user input capability, a battery, and a wireless transceiver; and a mount unit adapted to receive and hold the display units when folded within the mount unit, the mount unit further comprising a power arrangement configured to recharge the battery of the display units when the display units are received and held within the mount unit, a first wireless transceiver for communication with the wireless transceiver of each of the display units, and a communication arrangement for communication over a communications network; wherein the display units are removeable from within the mount unit for use separated from the mount unit.

The present invention also provides a display apparatus comprising at least one display unit, the or each display unit comprising a display screen with user input capability, a battery, and a wireless transceiver; a display frame structure for receiving and supporting at least peripheral portions of the or each display unit; and a mount unit adapted to receive and hold the display frame structure within the mount unit, the mount unit further comprising a power arrangement configured to recharge the battery of the or each display unit when the or each display unit is received within the mount unit, a first wireless transceiver for communication with the wireless transceiver of the or each display unit, and a communication arrangement for communication over a communications network; wherein the or each display unit is removeable from the mount unit for use separated from the mount unit.

The present invention also provides a display apparatus comprising a plurality of display units, each display unit comprising a display screen with user input capability, a battery, and a wireless transceiver; and a mount unit comprising a display frame structure for receiving and supporting at least peripheral portions of each of the display units, the mount unit further comprising a power arrangement configured to recharge the battery of the display units when the display units are received by the mount unit, a first wireless transceiver for communication with the wireless transceiver of the display units, and a communication arrangement for communication over a communications network; wherein the display units are removeable from the mount unit for use separated from the mount unit.

The present invention also provides a display apparatus comprising a plurality of display units, each display unit comprising a display screen with user input capability, a battery, and a wireless transceiver; and a mount unit comprising a hinge region and a plurality of frames hingedly connected to the hinge region, each frame configured to receive and hold a display unit, the mount unit further comprising a power arrangement configured to recharge the battery of the display units when the display units are received by the mount unit, a first wireless transceiver for communication with the wireless transceiver of the display units, and a communication arrangement for communication over a communications network; wherein the display units are removeable from the mount unit for use separated from the mount unit.

The present invention also provides a display apparatus comprising at least one display unit, the or each display unit comprising a display screen with user input capability, a battery, and a wireless transceiver; and a mount unit to receive and hold the or each display unit contained within the mount unit, the mount unit further comprising a power arrangement configured to recharge the battery of the or each display unit when the at least one display unit is received and held contained within the mount unit, a first wireless transceiver for communication with the wireless transceiver of each of the at least one display unit, and a communication arrangement for communication over a communications network; wherein the at least one display unit is removeable from within the mount unit for use separated from the mount unit.

The present invention also provides a display apparatus comprising a plurality of display units, each display unit comprising a detector arrangement to detect when at least one other display is arranged adjacently, a wireless transceiver to communicate display synchronization information to at least one adjacent display unit, and a display controller configured to control the display unit to display information comprising a sequence of information parts so that adjacent display units display information parts as a sequence of information parts.

The present invention also provides a display unit comprising a first display on a first face; a second display on a second face; a detection arrangement to detect when the display unit is turned to change the first display or the second display to face upwards; and a display controller to control the first and second display to display on one of the first or second displays a first information part of a sequence of information parts when the first display or second display is facing upwards, and to display on the other of the first and second displays a second information part incremented or decremented relative to the first information part in response to a detection by the detection arrangement.
