`
`CONDUCTOR PATTERN STRUCTURE OF CAPACITIVE TOUCH
`
`PANEL
`
`FIELD OF THE INVENTION
`
`[0001]
`
`The present invention relates to the field of touch panel devices, and in
`
`particular to a conductor pattern structure of a capacitive touch panel.
`
`BACKGROUND OF THE INVENTION
`
`[0002]
`
`Touch panels have been of wide applications in the fields of household ’
`
`appliances, communications, and electronic information appliances. An example
`
`of the common applications of the touch panel is an input interface of a personal
`
`digital assistant (PDA), an electrical appliance, or a game machine, etc. The
`
`current trend of integration of a touch panel and a display panel allows a user to
`
`use his or her finger or a stylus to point a control icon shown on the panel in order
`
`to execute a desired function on a PDA, an electrical appliance or a game machine,
`
`etc. The touch panel is also applied in a public information inquiry system to
`
`provide an efficient operation system for the public.
`
`[0003]
`
`A conventional touch panel comprises a substrate having a surface on
`
`which sensing zones are distributed for sensing a signal associated with the touch
`
`of a user’s finger or stylus to effect input and control. The sensing zones are
`
`made of transparent conductive membranes, such as Indium Tin Oxide (ITO),
`
`whereby a user may touch the transparent conducive membrane corresponding to
`
`a specific location shown on the display to effect operation of the device.
`
`[0004]
`
`The most commonly known types of touch panels include resistive
`
`panel, capacitive panel, infrared sensing panel, electromagnetic sensing panel, and
`
`sonic sensing panel.
`
`The capacitive touch panel employs a change in
`
`capacitance caused between a transparent electrode and the electrostatics of
`
`human body to induce an current based on which the touch location can be
`
`identified. The capacitive touch panel is advantageous in light transparency,
`
`l
`

`
`Page 17 of 364
`
`

`
`hardness, precision, response time,
`
`touch cycles, operation temperature, and
`
`initiation force and is thus most commonly used currently.
`
`[0005]
`
`In order to detect the location where a finger or a stylus touches the
`
`touch panel, a variety of capacitive touch panel techniques are developed. An
`
`example is US Patent No. 6,970,160, which discloses a lattice touch—sensing
`
`system for detecting a position of a touch on a touch-sensitive surface. The
`
`lattice touch-sensing system may include two capacitive sensing layers, separated
`
`by an insulating material, where each layer consists of substantially parallel
`
`conducting elements, and the conducting elements of the two sensing layers are
`
`substantially orthogonal to each other. Each element may comprise a series of
`
`diamond shaped patches that are connected together with narrow conductive
`
`rectangular strips.
`
`Each conducting element of a given sensing layer
`
`is
`
`electrically connected at one or both ends to a lead line of a corresponding set of
`
`lead lines. A control circuit may also be included to provide an excitation signal
`
`to both sets of conducting elements through the corresponding sets of lead lines,
`
`to receive sensing signals generated by sensor elements when a touch on the
`
`surface occurs, and to determine a position of the touch based on the position of
`
`the affected bars in each layer.
`
`[0006]
`
`US Patent No. 4,233,522 discloses a capacitive touch panel comprising
`
`an array of touch sensitive switch cells. Each switch cell includes a first and a
`
`second pair of series connected capacitors energized by a common signal source,
`
`the array of switch cells being arranged so that the first pair of capacitors are
`
`connected in first groups of switch cells, such as rows, to a corresponding first
`
`plurality of signal detectors, and the second pair of capacitors are connected in
`
`second groups of switch cells, such as columns,
`
`to a corresponding second
`
`plurality of signal detectors, the junctions of each pair of capacitors of a single
`
`switch cell being selectively coupled to ground by the body or other touch
`
`capacitive means for actuating a selected switch cell.
`
`[0007]
`
`US Patent No. 4,733,222 discloses a capacitance variation sensitive
`
`touch sensing array system including an array of electrodes, an array of drive lines,
`
`2
`
`Page 18 of 364
`
`Page 18 of 364
`
`

`
`a drive signal generator, and an array of sense lines.
`
`Each electrode is a
`
`connected series of conductive tabs and forms either a row or a column of the
`
`electrode array. Each drive line is capacitively coupled to a plurality of the
`
`electrodes. The drive signal generator generates and applies alternating signal
`
`packets to the drive lines. The sense line is capacitively coupled to a plurality of
`
`the electrodes so that signals are derived from the electrodes when drive signals
`
`are applied to the drive lines. The number of electrodes is equal to the product of
`
`the number of drive lines and the number of sense lines. Based on values
`
`derived from signals on the sense lines, a microprocessor provides information
`
`associated with touch by an operator.
`
`[0008]
`
`US Patent No. 5,880,411 discloses a method for recognizing a position
`
`made by a conductive object on a touch-sensor pad.
`
`Signals are sent to a control
`
`circuit of a host to identify the touch position. US Patent Nos. 6,414,671 and
`
`5,374,787 disclose the same technique.
`
`[0009]
`
`US Patent No. 7,030,860 discloses a transparent, capacitive sensing
`
`system particularly well suited for input to electronic devices. The capacitive
`
`sensor can further be used as an input device for a graphical user interface,
`
`especially if overlaid on top of a display device like an LCD screen to sense finger
`
`position and contact area over the display.
`
`[0010]
`
`US Patent No. 5,459,463 discloses a device for locating an object
`
`situated close to a detection area and a transparent keyboard incorporating the
`
`device. The device comprises a first set of detection zones connected so as to
`
`form lines which extend parallel to each other and to a detection area, a second
`
`set of detection zones connected to each other so as to form columns which extend
`
`perpendicularly to the lines, a scanning device which applies an electric signal to
`
`the lines and columns, and means for determining the position of an object by
`
`means of the scanning device.
`
`[0011]
`
`US Patent No. 6,498,590 discloses a multi—user touch system including
`
`a surface on which antennas are formed. A transmitter transmits uniquely
`
`3
`
`Page 19 of 364
`
`Page 19 of 364
`
`

`
`identifiable signals to each antenna. Receivers are capacitively coupled to
`
`different users, and the receivers are configured to receive the uniquely
`
`identifiable signals. A processor then associates a specific antenna with a
`
`particular user when multiple users simultaneously touch any of the antennas.
`
`[0012]
`
`US Patent No. 5,847,690 discloses a unitary display and sensing
`
`device, which integrates liquid crystal display module elements of a liquid crystal
`
`display module for detecting input on a flat panel display screen.
`
`[0013]
`
`All
`
`the prior art references described above provide teaching of
`
`detection touch of a user on a touch panel and all are comprised of structures of
`
`touch sensing elements. However, these known devices are all of a construction
`
`including two capacitive sensing layers spaced from each other with an insulation
`
`material to effect capacitive effect between the layers. This makes the structure
`
`of the panel very thick and is thus against the trend of miniaturization.
`
`Further,
`
`the conventional capacitive touch panel comprises a substrate on both surfaces of
`
`which two capacitive sensing layers are formed respectively.
`
`In this respect,
`
`through holes must be formed on the substrate to serve as vias and circuit layering
`
`must be adopted to properly connect conductor elements of the sensing layers.
`
`This complicates the manufacturing of the capacitive touch panel.
`
`[0014]
`
`Thus, it is desired to have a capacitive touch panel that overcomes the
`
`above drawbacks of the conventional capacitive touch panels.
