Image display device incorporating driver circuits on active substrate and other methods to reduce interconnects

An image display device comprising:

• a substrate;
• an active display region formed on the substrate, the active display region including a plurality of addressable rows and a plurality of addressable columns defining pixels;
• one or more driver ICs on the substrate, respective outputs of each driver IC coupled to respective ones of the plurality of addressable rows and the plurality of addressable columns, the one or more driver ICs adapted to drive the active display region to display an image;
• and
• a wireless receiver coupled to the one or more driver ICs, the wireless receiver adapted to wirelessly receive a wireless signal including an input video signal for display and couple the input video signal to the one or more driver ICs;
• wherein the wireless receiver comprises a wireless radio frequency receiver and includes a power inductor, the power inductor adapted to generate a power signal from a received wireless radio frequency signal, the power signal coupled to the one or more driver ICs, whereby a separate wireline input power signal is not required to be coupled to the one or more driver ICs.

A method for use in an image display device comprising:

• wirelessly receiving a signal inside a vacuum envelope of the image display device, the vacuum envelope sealing an active display region and one or more driver ICs on a substrate in a vacuum, the active display region including a plurality of addressable rows and a plurality of addressable columns defining pixels,
• wherein the signal comprises an input video signal;
• coupling the input video signal to the one or more driver ICs, the one or more driver ICs adapted to drive the active display region to display an image;
• and
• wirelessly transmitting the signal from outside of the vacuum envelope through a portion of the vacuum envelope.

A method for use in an image display device comprising:

• wirelessly receiving a signal inside a vacuum envelope of the image display device, the vacuum envelope sealing an active display region and one or more driver ICs on a substrate in a vacuum, the active display region including a plurality of addressable rows and a plurality of addressable columns defining pixels;
• wherein the signal comprises an input video signal;
• wherein the receiving step comprises wirelessly receiving a radio frequency signal inside the envelope;
• coupling the input video signal to the one or more driver ICs, the one or more driver ICs adapted to drive the active display region to display an image;
• deriving a power signal from the radio frequency signal having been received using power inductive coupling;
• and
• coupling the power signal to the one or more driver ICs.
