Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
61 words
A portable communication device comprising: a device housing; a wireless receiver carried by the housing and that
receives image data; a matrix display system carried by the housing; and a sequential color circuit connected to the matrix
display system such that the matrix display system
generates a plurality of color frames in sequence to form
a color image on the display.
Claim 2
Dependent Claim
198 words
The device of claim 1 and either a) wherein the matrix display system comprises a
liquid crystal display and a light source (optionally
wherein the light source comprises a plurality of light
emitting devices and/or a reflector around the light source
and/or comprises a red, a green and a blue light source); b) wherein the device comprises a portable
telephone; c) further comprising a diffuser; d) further comprising a lens to enlarge the image; e) wherein the display comprises an active matrix
display; f) further comprising a camera; g) wherein the display and the sequential color
circuit are positioned in a display module housing that is
attached to the device housing; h) wherein the device comprises a head mounted
display system; i) further comprising a control processor connected
to the sequential color circuit, and, optionally, further comprising a memory connected to the control
processor; j) wherein the display comprises an active matrix
circuit bonded to a transmissive substrate with an adhesive
layer; k) further comprising a microphone, an audio
receiver and an audio transducer; or l) further comprising a light source connected to
the sequential colour circuit, the circuit having a
controller that sequentially flashes the light source.
Claim 3
Dependent Claim
17 words
A device as claimed in claim 1 or 2 in which the
light source is a backlight.
Claim 4
Independent Claim
74 words
A method of displaying images with a portable
communication device comprising: providing a device housing that carries a wireless
receiver and a matrix display; receiving image data with the wireless receiver; and
further characterised by: generating a plurality of image subframes for each
color image frame, each subframe having a different color;
and displaying each subframe in temporal sequence on the
matrix display using a sequential color circuit to display
a color image frame.
Claim 5
Dependent Claim
191 words
The method of claim 4 further comprising either: a) providing a portable telephone housing that
contains the receiver; b) providing a display housing that houses the
display, the display housing being pivotably connected to
the device housing; c) the step of providing an active matrix liquid
crystal display; d) further comprising illuminating the display with
a light source connected to the sequential color circuit,
and, optionally, further comprising providing a light source having a
plurality of light emitting diodes of different colors that
are connected to the sequential color circuit; or comprises
a plurality of light emitting diodes; e) enlarging the image with an optical system and
positioning the optical system adjacent an eye of a viewer; f) providing a camera carried by the device housing; g) further comprising transmitting an image with a
transceiver in the device housing; h) providing an audio transducer receiving audio
with the receiver; i) providing a backlight having a red light source,
a green light source and a blue light source; j) connecting the device to a network with a
wireless transceiver; k) inserting a memory card into a memory interface
on the device housing.
Claim 6
Independent Claim
17 words
The method of any one of claims 4 and 5 wherein
the light source is a backlight.
