Description of the Invention: [Technical Field] The present invention relates to a touch device and particularly relates to a capacitive touch device. [Prior Art] The commonly used touch technologies for witnessing electronic devices are: resistive (resis|jve), surface capacitive (surface capacitive), projected capacitive (pr〇jected capacitive), surface acoustic wave (surface acoustic wave). , optics imaging, infrared, bending wave, and active digitizer. The first three technologies are relatively high in precision because of their small size, so they are suitable for smaller mobile devices or consumer electronics. In terms of resistive touch technology, from the screen to the contact system, data calculation and position determination, there are physical conditions in the technology. For example, contact detection creates a specific (four) degree of brittleness due to frequent contact closures, which in turn reduces the conduction efficiency of conductive film contact. In addition, the resistive _ technology does not reach the near-side sensation (the finger is close to the untouched state) and the more difficult to handle the multi-finger touch 验 之 鹤 原 _ _ and the resistive touch (four) Wei Ying board. =谷^Difficult to install the surface in the upper and lower layers, the direction of the 及 and the γ direction will be produced: When the Si finger or other control element is in contact with or close to the touch device, Ϊ your main two-r is easy to produce a hand shadow effect. That is to say, when picking up the curtain, if the hand bribes the finger close to the hiding surface, the conductive film surface and the panel side generate too much charge, the two couplings cause a large number of sensing errors.

The present invention can form the driving electrode 40 and the sensing electrode before the substrate 10, and then the driving electrode 4 A bridge wire 3G is formed on the 2G; the bridge wire 3G may be formed on the base 10, and the drive electrode and the inductor may be formed on the bridge wire 3G, or in other embodiments, the drive electrode 4〇 and the sense electrode π may also be formed by the same-conducting layer, for example, the driving electrode 4〇 and the bridge wire % are formed by the same conductive layer 'the sensing electrode 20 and the bridge, the wire 3〇 is formed by the same conductive layer, or the driving electrode 40, Both the sensing electrode 2〇 and the bridge wire 3〇 are formed by different conductive layers, and the relative positions of the upper and lower sides are not limited by the drawings. It is particularly noted that in the present invention, the 'peripheral electrode strip 42 (ie, the first electrode gauge has a first width W1 'the inner electrode strip 44 has a second width W2 on the first direction 丨2, and the first width W1 is smaller than the second Width W2. For example, in the present embodiment, the ratio of the first width wi to the second width W2 is substantially less than or equal to G8 and greater than or equal to 0.%; preferably, the first width W1 and the second width W2. The ratio is approximately 201120717, which is less than or equal to G.7 and greater than or equal to G.G7; or more preferably, the ratio of the first width W1 to the second width W2 is substantially less than or equal to 〇66 and greater than or equal to 〇0941. The first width W1 of the strip 42 is smaller than the second width W2 ′ of the inner electrode strip 44. Therefore, the distance between the phase (four) capacitor units (6) in the first direction 12 is reduced, and the sensing signal detected by the adjacent capacitive sensing unit 60 is detected. The large overlapping area of each other can effectively improve the surface sensitivity, and increase the linearity of the sensing device 15 in the first direction 12.

For example, the display panel 13A can include a substrate 1 , a substrate 16 , and a liquid crystal layer 18 disposed between the substrate 10 and the substrate 16 . The touch sensing device 150 can be formed on the outer side of the substrate 10 , that is, the touch sense. The measuring element 15〇 and the liquid crystal f 18 are located on opposite sides of the substrate 10. The substrate 16 may include, for example, a thin film capacitor: a body array CthinfilmtransistGraj^ substrate, and the substrate 1 (for example, may include a color filter substrate, but is not limited thereto Referring to FIG. 1 and FIG. 2 together, when a conductor or other control member 70 such as a finger or a stylus touches or is adjacent to the touch sensing element 15 , the control element 7 改变 changes the drive electrode 40 ef . ^ The sensor consumes the signal size of the sensing electrode 2〇, and the sensing circuit can determine the touch position. Comparative Example: As shown in FIG. 3, the sensing electrode 32 of the comparative example includes the main electrode strip 322 and the branch electrode portion 324. ; The driving electrode 340 of each of the capacitance sensing units 360 includes a peripheral electrode strip 342 and an inner electrode strip 344 ′ and the bridge and the line 33 〇 can connect the driving electrode 340 across the sensing electrode 320 201120717. The main example of the comparative example and the embodiment of the present invention The difference is that the width W3 of the peripheral electrode strip 342 of the comparative example is equal to the width W3 of the inner electrode strip 344. As shown in FIG. 4, 'the fold line Χίο, the fold line X2o, the fold line X3o, the fold line χ4〇, and the fold line ο5ο are comparative examples, respectively. Each of the capacitive sensing units 36 is in the aforementioned first direction 12 and the broken line χ3η is a sense of the capacitive sensing unit 60 in the first direction 12 of the preferred embodiment of the present invention. The measurement signal, wherein the capacitance sensing unit 360 of the fold line 与3〇 and the capacitance sensing unit 60 of the fold line η3η are substantially disposed on the same coordinate. 4, since the first width wi of the peripheral electrode strip 42 of the present invention is smaller than the second width W2 of the inner electrode strip 44 (as shown in FIG. 1), the adjacent capacitive sensing units in the first direction 12 The distance between 60 is reduced. In this way, the sensing signals detected by the adjacent capacitive sensing units 6〇 can have a large area of overlap with each other. As shown in FIG. 5 and FIG. 6 , when the control element 7 划 is linearly traced through the touch sensing component 150 of the present invention and the touch sensing component of the comparative example (consisting of the array of capacitive sensing units 360) When the capacitance sensing unit 6 本 of the present invention has a significant linearity, the touch position can be accurately sensed in the first direction U or the second direction ,, so that the sensed position is sensed. The trajectory (Fig. 5) can be closer to the linear trajectory of the actual touch. In contrast, since the sensing ability of the comparative touch control element in the first direction is less than ideal, the trajectory sensed by the touch field detecting element of the scent (Fig. 6) has a poor linearity. In addition, the touch sensing element and the capacitive sensing unit of the present invention are not limited to the structure of FIG. 2. FIG. 7 is a cross-sectional view of the capacitive sensing unit 6Q of the present invention applied to another touch display device 200, and FIG. 8 is a cross-sectional view of the capacitive sensing unit 6 of the present invention applied to another touch display device 400. As shown in FIG. 7 , the touch device 170 may include an auxiliary substrate 10 and a touch sensing device disposed on the auxiliary substrate 10 , and the display panel may include, for example, a first substrate 101 and a second substrate 16 , and The liquid crystal layer 18 is disposed between the first substrate 11 and the second substrate 16 =. Here, the lion substrate may be such that the valve substrate does not include a colored tear film and the substrate 11 may be a color filter substrate, but is not limited thereto. After the touch device m and the display panel 13G are formed, the touch device 170 and the display panel 13 can be assembled into a fine control display device in any suitable manner. For example, the touch device is provided with a 17G optical glue or a frame attached thereto. The surface of the display panel 13G is formed into the touch display device 200. Xi
