The wire distributing structure comprises the projected capacitive type touch panel, a plurality of signal lines and touch chips, wherein the projected capacitive type touch panel is connected with the touch chips through the signal lines, the widths of the signal lines gradually increase from far to near according to the distances between the projected capacitive type touch panel and the touch chips, and the lengths of the signal lines gradually decrease from near to far according to the distances between the projected capacitive type touch panel and the touch chips.
Description
Technical field
The utility model relates to contact panel technical field, particularly a kind of wire structures that improves projected capacitive touch panel signal conformance.
Background technology
The straight cabling of the general employing of detection signal line of tradition projected capacitive touch panel, the sensor of panel zones of different (sensor) is different in size to the signal wire of touch-control chip (IC), X/Y direction cabling from the sensor close to touch-control IC is shorter, impedance is less, and longer from the X/Y direction cabling of the sensor away from touch-control IC, impedance is larger, and signal transmission time is long, decay is more serious, easily causes touch-control IC misoperation; Along with contact panel is to large-sized development, projected capacitive touch panel size is also done larger and larger, zones of different sensor to the signal line impedance of touch-control IC differ cause signal transmission time and attenuation degree difference more serious.
The straight cabling mode of the common projected capacitive touch panel signal wire of tradition as shown in Figure 1, the path at the sensor of projected capacitive touch panel zones of different to touch-control IC differs, and impedance varies, a little less than the intensity of signal also has and has by force:
Block (1) is by signal wire X/Y direction cabling (i.e. signal wire X1, Y1 in figure) is the longest to touch-control IC path, impedance is maximum, and signal passes to that time of touch-control IC is the longest, intensity is the most weak;
Block (2) is minimum to touch-control IC shortest path, impedance by X/Y direction cabling (i.e. signal wire X4, Y4 in figure), and shortest time, intensity that signal passes to touch-control IC are the strongest;
Other block paths, impedance are all in the region of block (1) and (2) value;
This kind of cabling mode easily cause signal transmission time and signal intensity profile inhomogeneous.
For this reason, the utility model provides a kind of wire structures that improves projected capacitive touch panel signal conformance, to solve the problems of the technologies described above.
Utility model content
The utility model is for prior art above shortcomings, a kind of wire structures that improves projected capacitive touch panel signal conformance is provided, mainly from projected capacitive touch panel cabling mode angle, by improving zones of different sensor to signal wire length and the width of touch-control chip (IC), make impedance, signal transmission time and the intensity of each detection signal line consistent, can effectively improve touch-control IC detection sensitivity and accuracy.
The utility model is achieved through the following technical solutions:
Improve a wire structures for projected capacitive touch panel signal conformance, comprise projected capacitive touch panel, some signal wires and touch-control chip, projected capacitive touch panel is connected with touch-control chip by some signal wires:
The width of some signal wires from the close-by examples to those far off increases successively according to the distance between projected capacitive touch panel and touch-control chip, and the length of some signal wires from the close-by examples to those far off reduces successively according to the distance between projected capacitive touch panel and touch-control chip.
Preferably, the signal wire that connects the distance farthest between projected capacitive touch panel and touch-control chip is straight Wiring structure, to reduce the signal transmission distance of the distance farthest between projected capacitive touch panel and touch-control chip; Remaining signal wire is " several " character form structure, to increase the signal transmission distance between projected capacitive touch panel and touch-control chip.
Preferably, the width of some signal wires from the close-by examples to those far off increases a times of width of the nearest signal wire between projected capacitive touch panel and touch-control chip successively according to the distance between projected capacitive touch panel and touch-control chip.
Accompanying drawing explanation
Shown in Fig. 1 is the wire structures schematic diagram of existing projected capacitive touch panel;
Shown in Fig. 2 is wire structures schematic diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; embodiment based in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, below in conjunction with accompanying drawing, take specific embodiment and be further explained as example, and each embodiment does not form the restriction to the utility model embodiment.
Please refer to Fig. 2, for solving traditional projected capacitive touch panel, at the sensor of zones of different, to touch-control IC(, be touch-control chip) path each signal line impedance causing different in size, signal transmission time and the inconsistent problem of intensity, main by changing cabling mode and the trace width of projected capacitive touch panel, make impedance, signal transmission time and the intensity of each signal line consistent.
Its principle is the resistance characteristic according to wire, and cabling is more long thinner, and impedance is larger; Cabling is more short thicker, and impedance is less.
When making projected capacitive touch panel:
X/Y signal wire away from touch-control IC can adopt the straight cabling of tradition, increases trace width simultaneously;
X/Y signal wire close to touch-control IC can adopt " several " font mode to increase track lengths, dwindles trace width simultaneously.
In Fig. 2, making signal wire X1 width is 3 times of signal wire X4 width, and signal wire Y1 width is 3 times of signal wire Y4 width; Coordinate the track lengths that increases signal wire X4/Y4 simultaneously, so with the impedance of line equalize signal X1/Y1 and X4/Y4, signal transmission time and signal intensity are reached or approach consistent.
Block (1) diminishes to the impedance of touch-control IC by thicker straight shape signal wire X1/Y1, and signal passes to time decreased, the strength-enhanced of touch-control IC, approaches mean value;
Block (2) becomes greatly to the impedance of touch-control IC by thinner " several " font signal wire X4/Y4, and signal passes to time increase, the remitted its fury of touch-control IC, approaches mean value;
In like manner other blocks all approach mean value, thereby make impedance, signal transmission time and the intensity of each signal line consistent, can effectively improve touch-control IC detection sensitivity and accuracy.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
