The tradition touch panel is a touch-control device independently, it can be arranged at a display panel or display device surface, and conductive film and most septs of generally include conducting glass substrate, being located on the conducting glass substrate are located between conducting glass substrate and the conductive film.Apparent surface between conducting glass substrate and conductive film is respectively arranged with a transparency conducting layer, and it can electrically connect with lead, electrically connects with external control circuit via flexible circuit board again.The principle of operation of the touch panel of prior art is via the conductive film of finger presses panel surface, make press points generation change in voltage, can calculate the position of press points by the variable quantity of voltage, and will represent the input signal of this position to pass by transparency conducting layer, lead and flexible circuit board.

In addition, the overlapping of first substrate 12 and second substrate 14 partly is defined as the viewing area of embedded touch-sensitive type panel 10, and the part enlarged diagram and the equivalent circuit diagram of its component placement please refer to Fig. 2 and Fig. 3.Embedded touch-sensitive type panel 10 comprises that multiple display area 68 and most pixels 16 are positioned at viewing area 68, and each pixel 16 comprises that an at least one data line 18 and a sensing signal line 20 crisscross at least one sweep trace 22.In addition, each pixel 16 comprises that in addition an image pixel district 24 and pushes induction zone 26.Image pixel district 24 comprises thin film transistor (TFT) 28, liquid crystal capacitance C
LCWith the first storage capacitors C
ST1(being shown in Fig. 3), wherein the drain electrode of thin film transistor (TFT) 28 electrically connects a pixel electrode 30.The major function in image pixel district 24 is to transmit signal of video signal to pixel electrode 30 via signal wire 18 from thin film transistor (TFT) 28, with shared electrode Vcom36 effect formation electric field and liquid crystal is turned to, and then demonstrates image frame.Push 26 of induction zones and comprise sensing structure 32 and thin film transistor (TFT) 34, wherein sensing structure 32 comprises the part of shared electrode 36 on first substrate, 12 inside surfaces, when first substrate 12 is subjected to pressed by external force, shared electrode 36 on first substrate 12 can contact with the electronic package on second substrate 14 and produce sensing signal, can be sent to sensing signal line 20 and embedded touch panel 10 is controlled by thin film transistor (TFT) 34, as shown in Figure 3.In addition, comprise in addition between first substrate 12 and second substrate 14 that most photoresist septs (photoresist spacer) 52 are located in the pixel 16 or between the pixel 16, ccontaining liquid crystal layer to support gap between first substrate 12 and second substrate 14.
As previously mentioned, because existing embedded touch-sensitive type panel is more near the edge, viewing area the time, need bigger pressed by external force just can make first substrate 12 distortion downwards and the generation sensing signal more, therefore embedded touch-sensitive type panel of the present invention is provided with most the sensing areas with different sensing gap promptly at this problem in the viewing area.Please consult Fig. 1 again, the embedded touch-sensitive type panel 10 of present embodiment comprises first sensing area 40 and second sensing area 42, is defined on first substrate 12 and second substrate 14, and wherein second sensing area 42 is around first sensing area 40, and by 38 in frame glue district around.In alternate embodiment, the outside that second sensing area 42 does not need only to be arranged on first sensing area 40 around first sensing area, 40, the second sensing areas 42 gets final product, and just second sensing area, 42 to the first sensing areas 40 are near frame glue 38.
Please refer to Fig. 4, Fig. 4 is the diagrammatic cross-section of the subelement of embedded touch-sensitive type panel 10 shown in Figure 1, and wherein the direction of arrow is represented by the middle body of the viewing area of embedded touch-sensitive type panel 10 direction to the marginal portion.The lower surface of first substrate 12 comprises that one shares electrode 36, covers the surface of photoresist sept 52, wherein the shared electrode 36 preferable transparency conducting layers that comprise.In addition, because embedded touch-sensitive type panel 10 comprises first sensing area 40 and second sensing area 42, so it also comprises two kinds of sensing structures: first sensing structure 44 and second sensing structure 46 lay respectively in first sensing area 40 and second sensing area 42 of first substrate 12 and second substrate 14.First sensing structure 44 comprises sensing electrode 44a and first time sensing electrode 44b on first, wherein sensing electrode 44a is the part of shared electrode 36 on first, and first time sensing electrode 44b comprises a transparency conducting layer, and its material can be same as the material of pixel electrode 30.Sensing electrode 44a and first time sensing electrode 44b have a gap on first, are the first sensing gap G that first sensing structure 44 is had

2, only to reach the purpose that needs less outer acting force just can make sensing electrode 46a on second be contacted with second time sensing electrode 46b and produce sensing signal.
Moreover, embedded touch-sensitive type panel 10 of the present invention comprises that in addition a black-matrix layer 50 is located at the lower surface of first substrate 12, it is shared electrode 36 and covers, and second substrate, 14 upper surfaces are provided with most layer film layers, with formation thin film transistor (TFT) 28,34, and form first and second bed hedgehopping structure 56,58 simultaneously.48 of the liquid crystal layers of embedded touch-sensitive type panel 10 of the present invention are located between first substrate 12 and second substrate 14, and are positioned at frame glue 54.In addition, embedded touch-sensitive type panel 10 of the present invention comprises that also most supporting constructions 66 are located between first substrate 12 and second substrate 14, it comprises the photoresist sept 52 of being located at first substrate, 12 surfaces and the thin layer of being located at most storehouses on second substrate 14, has fixing gap by photoresist sept 52 and surperficial shared electrode 36 thereof and inconsistent the making between first substrate 12 and second substrate 14 of below thin layer.In addition, also alternative is provided with attached supporting construction (not icon) near supporting construction 66, its structure calcaneus branches support structure 66 is approximate, only the photoresist sept on first substrate, 12 surfaces does not contact second substrate 14, and when 12 distortion of first substrate, the photoresist sept just can contact second substrate 14, can increase the effect of support.
Please refer to Fig. 5 and Fig. 6, Fig. 5 is for looking synoptic diagram on second embodiment of embedded touch-sensitive type panel of the present invention, and Fig. 6 is the part assembly diagrammatic cross-section of embedded touch-sensitive type panel shown in Figure 5.Embedded touch-sensitive type panel 100 of the present invention comprises first substrate 102 and second substrate 104, and both are by frame glue 128 fixing and parallel being oppositely arranged, and its center glue 128 is arranged in the frame glue district 106.Could produce the shortcoming of sensing signal more near the frame glue district big more outer acting force of 106 needs for the touch panel that improves prior art, embedded touch-sensitive type panel 100 of the present invention has different sensing areas by the middle body of viewing area to marginal portion definition, for example comprises that first sensing area 108 is located at the middle body of first substrate 102 and second substrate 104, second sensing area 110 and is located at the periphery and the edge sensing area 112 of first sensing area 108 and is located at second sensing area, 110 outsides and is adjacent to frame glue district 106.
Please refer to Fig. 6, direction indication shown in the arrow is by the middle body of embedded touch-sensitive type panel 100 direction to the marginal portion.First sensing area 108, second sensing area 110 and edge sensing area 112 comprise most first sensing structures 114, second sensing structure 116 and edge sensing structures 118 (only draw among the figure each one with as an illustration) respectively.First sensing structure 114 comprises sensing electrode 114a and first time sensing electrode 114b on first, has the first sensing gap G between the two
1 Second sensing structure 116 comprises sensing electrode 116a and second time sensing electrode 116b on second, has the second sensing gap G between the two
2And edge sensing structure 114 comprises sensing electrode 118a and the 3rd time sensing electrode 118b on the 3rd, has edge sensing gap G between the two
3First, second and the 3rd time sensing electrode 114b, 116b, 118b are located at the surface of the first bed hedgehopping structure 120, the second bed hedgehopping structure 122 and the 3rd bed hedgehopping structure 124 respectively, and the thickness of the 3rd bed hedgehopping structure 124 is greater than the second bed hedgehopping structure 122, and the thickness of the second bed hedgehopping structure 122 is greater than the first bed hedgehopping structure 120.So, the first sensing gap G
1Greater than the second sensing gap G
2, and the second sensing gap G
2Greater than the 3rd sensing gap G
3Therefore, compared to first sensing area 108, first substrates 112 in the edge sensing area 112 only need that deformation a little is recessed can be made on the 3rd sensing electrode 118a contact with the 3rd time sensing electrode 118b and produce sensing signal, needed outer acting force during with minimizing touch control operation edge sensing area 112.
In addition, be similar to the first embodiment of the present invention, utilize frame glue 128 to be fixed between first substrate 102 and second substrate 104, and support gap between first substrate 102 and second substrate 104 by most the supporting constructions 126 that comprise that photoresist sept 130 and film stack architecture 132 form.
What deserves to be mentioned is that in other embodiments, supporting construction can be different according to the design of different display panels with the rete design of each bed hedgehopping structure, for example the photoresist sept can be arranged at the surface of second substrate etc.In addition, the application of the structural design of touch panel of the present invention is not limited to previous embodiment, also can be applicable in the touch-control device of independent running, or in the display panel of integration and other type.For example, according to spirit of the present invention, one touch-control device can be provided, its sensing structure also can be located in the two parallel opposing substrates, and fix the gap of two substrates with frame glue and supporting construction, and this touch-control device comprises that most are pushed induction zone, arrange with matrix-style, and respectively push induction zone and comprise a sensing structure, be electrically connected at a sensing signal line.This touch-control device definition in addition has two to a plurality of sensing areas, and the sensing structure in each sensing area has different sensing gap.By the sensing signal line of each sensing control zone, touch-control device of the present invention can will send external circuit to through control signal or sensing signal that touch-control produced, controls with the device to the outside.For example, touch-control device of the present invention can be arranged at the place ahead of a monitor or display, so that the touch function to be provided.
Compared to prior art, embedded touch-sensitive type panel of the present invention comprises most sensing areas, the nearer sensing area of its middle distance frame glue is around distance frame glue sensing area far away, and apart from the distance of frame glue and have different sensing gap, wherein the sensing gap near frame glue is more little more according to each sensing area.Under less sensing gap design, first substrate only needs less deformation quantity just can produce sensing signal.Therefore, but each sensing area of embedded touch-sensitive type panel equalization of the present invention produces the required acting force of sensing signal, effectively improves the prior art touch panel needs big more acting force more near edge shortcoming.The structural design of embedded touch-sensitive type panel according to the present invention, need not increase extra technology or material, only need revise the design of thin layer a little, just can make sensing structure with different sensing gap, and make other basic electronic component of display panel simultaneously, with the touch control display panel that provides with low cost and external form is frivolous.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
