A touch panel includes a substrate, a sensing array, a plurality of first connection lines and at least two button sensing pads. The substrate has an active region and a peripheral region disposed on at least one side of the active region. The sensing array is disposed in the active region, which includes a plurality of first sensing electrode series disposed in the active region along a first direction and a plurality of second sensing electrode series disposed in the active region along a second direction. The first and second sensing electrode series intersect and form a plurality of sensing units. The first connection lines are disposed in the peripheral region and electrically connected to the first sensing electrode series respectively. The at least two button sensing pads are disposed in the peripheral region, and electrically connected to at least two first connection lines respectively to form a virtual button.

Touch panel, touch display panel and touch signal sensing method

A touch panel including a substrate, at least one touch-sensing unit, at least one connecting pad, at least a testing line, at least one ESD protection circuit, and a first isolation layer is provided. The touch-sensing unit is disposed on the substrate. The connecting pad is disposed on the substrate and electrically connected to the touch-sensing unit. The testing line is disposed on the substrate, electrically connected to the connecting pad, and extends to at least an edge of the substrate. The ESD protection circuit is disposed in the edge of the substrate and electrically connected to a ground voltage, wherein a vertical projection of the testing line to the substrate and that of the ESD protection circuit to the substrate is at least partially overlapped. The first isolation layer is disposed between the testing line and the ESD protection circuit.

Touch panel and manufacturing method of touch display panel

A touch device includes a touch panel that includes driving lines, sensing lines, a virtual key, a self-sensing line, and a shielding line. The touch panel has a display region and a non-display region. The driving lines extend along a first direction in the display region and further extend into the non-display region. The sensing lines extend along a second direction in the display region and extend into the non-display region. The first direction is different from the second direction. The virtual key is located in the non-display region and between the driving lines and the sensing lines to shield the driving lines from the sensing lines. Each of the self-sensing line and the shielding line is located in the non-display region, connected to the virtual key, and located between the driving lines and the sensing lines to shield the driving lines from the sensing lines.
