(As shown in the fourth figure), in the present embodiment, each of the vertical axis electrode lines (21) is composed of a plurality of transparent electrodes arranged in a longitudinally spaced manner, and the transparent electrodes are spaced apart from each other by a horizontal axis electrode line (22); Providing a patterned insulating layer on the lower surface of the rigid substrate (10) (30) The patterned insulating layer (3Q) forms a visible area hollow portion (31) corresponding to at least the end of each of the longitudinal axis electrode lines (21); and a corresponding horizontal axis and vertical axis electrode line (21, 22) near the shielding pattern (1)) - formed on the side of the active area hollow portion (32) (as shown in the fifth figure); and then as shown in the sixth figure, further patterned on the patterned insulating layer (10) a transparent conductive film (40), as shown in the seventh figure, the transparent conductive film (40) is subjected to a patterning process to form a cross-bridge wire (4) corresponding to the visible area hollow portion (8)) and a corresponding moving area hollow portion (32) forming a guiding line (12)' to form a capacitive touch panel as shown in the first figure, since the cross-bridge wires (41) are insulated from the horizontal axis electrode lines (22), the foregoing The transparent electrode of the vertical axis electrode line (21) can be electrically connected by (four) cross-bridge wires (4) without being short-circuited with the horizontal axis electrode line (22). The patterned conductive film (20) may also be formed on the upper surface of the lower substrate. In this case, the order of forming the layers of the touch panel may be referred to the lower surface of the hard substrate (1〇) of the eighth to fifteenth drawings. Forming the masking pattern (1)) (shown in FIG. 8). Then, a transparent conductive film (120) is plated on the lower surface of the hard substrate (10) (as shown in FIG. 9); and the transparent conductive film is further 12〇) patterning to form the aforementioned guiding line (12') (as shown in the tenth figure); 6 M355426 Please refer to the tenth-pi ^ - one figure, the present invention provides the soil in the second embodiment The patterned conductive film (20') is formed on the patterned conductive film ί2η, +1, _, and 衣衣回;) in the present embodiment, the plurality of vertical axis electrode lines The horizontal line electrode line (22,) in which the electrode lines (21') are staggered constitutes one end of the guide line (12,) at one end of each electrode line (21, 22), and the substrate (1〇) is (4) Polar circuit (2V) The transparent electrode arranged in the door & the transparent electrode is made with the horizontal axis electrode line (22') Between the two layers, a patterned insulating layer (30,) is disposed on the substrate (50), as shown in Fig. 12, the patterned insulating layer (3 〇,) corresponds to each longitudinal axis electrode line. : at least the end of the transparent electrode is formed into a visible area hollow portion (7), and the end of each electrode line (21, 22,) is exposed outside the patterned insulating layer 0) so as to be a hard f substrate ( 1Q) When combined with the lower substrate (50), the guiding line is electrically connected to the end of each electrode line (21, 22,); the connector is as shown in the thirteenth figure, on the lower substrate (50) ) on the comprehensive money on a transparent conductive film (4D,), so that the dielectric film (10),) through the process, / 1 should be visible in the visible area (31,) cross-bridge wire (41 ') ( As shown in Fig. 14, the cross-bridge wires (4) are insulated from the horizontal axis electrode lines: the transparent electrodes of the respective longitudinal axis electrode lines (21,) can be made by the bridges The wire (41) is electrically connected in series without being short-circuited with the horizontal axis electrode line (22,); after that, as shown in the fifteenth figure, the lower substrate (5〇) Electrode lines (21, 22,) and a hard substrate (1〇) of the patterned conductive film (2〇) of the lower substrate (5Q) are bonded to the hard substrate (by a sealant (60)) Guide line connection. Compared with the prior art, the M355426 combines the touch panel and the protective lens separately and in combination with the optical adhesive attaching step. This design provides the lower surface of the hard substrate as the structure of the touch panel structure. In the case of line interleaving, it is designed to provide a cross-bridge conductor through the insulating layer to make the lines insulated from each other = the wrong area, and the area of the wiring is first formed by the color resistance process to form a mask pattern; further, the upper surface of the hard substrate is used as a finger Touch and with the existing Cover Lens function, this creation uses this innovative structure to integrate the integrated protective lens with the touch panel structure. The innovative structure provided by this creation completely eliminates the material cost of the additional protective lens and the material f of the optical adhesive (〇CA) and the manufacturing cost (including manufacturing cost and yield loss), and streamlines the touch module. The manufacturing process can significantly shorten the process time and reduce the cost. It also provides a high-yield solution for the high-tech door-to-cement large-size protective lens (C〇Ver Lens), and then reduces the layer structure to reduce the overall touch. The control module conforms to the light and thin appeal of today's consumer electronic products.
