TOUCH PANEL, DISPLAY DEVICE AND TOUCH DRIVING METHOD

摘要

A touch panel, a display device and a touch driving method are disclosed. The touch panel includes a plurality of first self-capacitance electrodes. The plurality of first self-capacitance electrodes are at least distributed in two areas; the first self-capacitance electrodes at corresponding positions in the at least two areas are electrically connected with each other; and at least one in each group of electrically connected first self-capacitance electrodes corresponds to one row-scanning electrodes, which is configured to determine the touch condition of each first self-capacitance electrode in the same group of electrically connected first self-capacitance electrodes. The disclosure reduces the total amount of leads and hence reduces touch blind areas and is favorable to a narrow-bezel design.

主权项

1. A touch panel, comprising a touch structure comprising:
at least one row of first self-capacitance electrodes disposed in a first area and at least one row of first self-capacitance electrodes disposed in a second area, in which each row of first self-capacitance electrodes comprise a plurality of first self-capacitance electrodes; the at least one row of first self-capacitance electrodes in the first area correspond to the at least one row of first self-capacitance electrodes in the second area; each first self-capacitance electrode in the first area and the corresponding first self-capacitance electrode disposed in the second area are electrically connected with each other; and at least one row-scanning electrode disposed in the first area and/or the second area, in which each row-scanning electrode corresponds to one row of first self-capacitance electrodes, comprises a body portion extended along the extension direction of the one row of first self-capacitance electrodes corresponding to the row-scanning electrode, and is adjacent to and insulated from the corresponding first self-capacitance electrodes; wherein at least one in each group of mutually electrically connected two first self-capacitance electrodes corresponds to the row-scanning electrode.
