The invention provides a resistance type touch screen which comprises a first substrate carrying a first conductive film, a second substrate carrying a second conductive film, a first electrode formed on the edge of the first substrate and a second electrode formed on the edge of the second substrate; and the resistance type touch screen is characterized in that the second substrate is provided with a blank electrode wire, a second breakover part is arranged at the output end of the blank electrode wire, a conductive adhesive is formed on the second breakover part, a first breakover part deadagainst the second breakover part is arranged at the input end of the first electrode, and the blank electrode wire and the input end of the second electrode extend to form an exposed conductive electrode on a prearranged position of the second substrate. The blank electrode wire on the second substrate and the input end of the second electrode extend to form the exposed conductive electrode structure at the prearranged position on the second substrate, therefore, the problems of damage and deformation of the film substrate in the prior art are well solved, the overall thickness is maintaineduniform, and the overall appearance of the touch screen is improved.
Description
Technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to an electrode network connection form of a resistive touch screen. Background technique [0002] In the prior art, the main structure of the four-wire resistive touch screen is as figure 1 Shown, including: [0003] The glass substrate 11 has a conductive film 111 (usually an ITO conductive layer) printed on the inner frame of one surface, and the ITO conductive layer is not printed on the periphery of the glass substrate; [0004] The electrode layer 12 (usually silver paste) is printed on the peripheral edge of the glass substrate 11 in a thin printing method. The electrode layer 12 is divided into two sections. Each section of the electrode is provided with an input terminal, which is an input terminal 121. And 122; [0005] The insulating layer 13 is printed on the electrode layer 12, and the insulating layer 13 is formed with a gap 131 on the same side of the input e...
