Description of the Invention: [Technical Field] The present invention relates to a touch display panel and in particular to an integrated touch Controlled display panel (integrated touch display panel). [Prior Art] In recent years, with the rapid development of various applications such as information technology, wireless mobile communication, and information appliances, many information products are input devices for the purpose of being more convenient, lighter and lighter, and more humanized. It has been transformed from a traditional keyboard or mouse to a t〇uch display panel. In today's general touch display panel design, the classification principle of the touch sensing mode can be roughly divided into resistive, capacitive, optical, acoustic, and electromagnetic, among which resistive and capacitive. For the mainstream; classification by structure, it can be divided into two types: the adhesive type and the built-in type. In the case of a resistive touch panel, the biasing force of a single point of pressing causes the originally separated conductive layers to be in contact with each other to conduct a voltage drop, thereby generating a voltage drop at the conduction; The position can be used to determine the coordinates on the panel where the press occurred. In the case of a capacitive touch panel, the main principle is to generate a uniform low-voltage electric field in the inner and outer conductive layers. When a conductor (such as a human finger) comes into contact with it, an electrostatic bond is generated, thereby generating a slight capacitance change; To measure the change in capacitance: Set ' to determine the coordinates at which the contact occurs on the panel. The general advantage of the capacitive touch panel is that it can be hand-written and multi-touch. However, the user has to touch the conductor material to operate the tribute gloves. Or it is a non-conductor material (such as an I's workmanship. The general advantage of the resistive touch panel is that it can be operated == wide operation] However, the limitation is that it cannot be written by hand: «Γ externally mounted control design makes the display panel Thick itself, 1 production cost from the touch of less difficult to build

The second bridge wire 234 is connected in series with two adjacent two sensing pads 232 to form a second sensing series 230. The substrate 210 has a first dielectric layer 240 having a plurality of vias (not shown in this figure). These vias correspond to the second sensing pad 232' of the lower layer and expose portions of the corresponding second sensing pad 232. The second bridge wire 234 is connected to the corresponding second sensing pad 232' by the corresponding via window to form the second sensing series 230.
