The invention provides a four-wire resistance type touch screen and a manufacturing method thereof. The four-wire resistance type touch screen comprises a first base layer (1), a second base layer (2), a first conducting layer (3), a second conducting layer (10), an insulating layer (4), at least four poles (6) and at least four pole leading-out wires (9), wherein the pole (6) positioned on the first conducting layer (3) is electrically connected with the first conducting layer (3) and connected with the second conducting layer (10) in an insulating way; the pole (6) positioned on the second conducting layer (10) is connected with the first conducting layer (3) in the insulating way and electrically connected with the second conducting layer (10); and each pole (6) and the pole leading-out wire (9) connected with the pole (6) are constructed into a whole by a flexible printing circuit board. The four-wire resistance type touch screen has the advantages of high resolution, obvious simplified manufacturing technology, low cost, short manufacturing period, lower product reject ratio, and the like.
Description
technical field [0001] The invention relates to a structure of a touch screen and a manufacturing method thereof, in particular to a structure of a four-wire resistive touch screen and a manufacturing method thereof. Background technique [0002] As a convenient human-computer interaction interface, touch screen has entered various fields of our life and work, especially in the fields of portable electronic consumer goods and public inquiries. Existing touch screens are usually divided into four basic types: resistive Touch screen, capacitive touch screen, infrared technology touch screen and surface acoustic wave technology touch screen. Among them, the resistive touch screen is the lowest cost and most widely used touch screen. Resistive touch screens are usually divided into four-wire resistive touch screens and five-wire resistive touch screens according to the number of leads. Among them, four-wire resistive touch screens are the most widely used. [0003] Such as fi...
