Description of the Invention: [Technical Field] The present invention relates to a touch display panel and a touch display, and in particular to a touch with integrated control circuit Controlled display and touch display panel. [Prior Art] FIG. 1 continues with a circuit block diagram of a touch panel that is not conventional. Please refer to FIG. 1 ''The conventional touch panel 1'' includes a touch element array 1Q2 and a driving circuit board 104. The driving circuit board 1〇4 is coupled to the touch element array 1〇2 through the flexible circuit board 106. A driving circuit is disposed on the driving circuit board 1-4, and includes a control unit 112, a memory 114, and a plurality of passive components such as a resistor R or a capacitor C. The touch element array 102 has a plurality of touch elements, such as 122 and 124, arranged in an array on a substrate 126. The touch elements can be roughly classified into a capacitive type and a resistive type. However, whether the touch component is resistive or capacitive, the sensing principle is similar, that is, when a conductor object (such as a finger) contacts the touch component on the surface of the touch component array 102, the touch component Electrical characteristics (such as resistance or capacitance) change, causing the bias of the touch element to change. Thereby, when the control unit 112 senses that the bias of the touch element is changed, the position at which the conductor object contacts the touch element array 1〇2 can be calculated. With the advancement of semiconductor manufacturing, human dependence on electronic products is gradually increasing.
