Abstract:
1. A capacitive touch panel structure, comprising: a display module including a base substrate, a transistor layer and a filter set that are sequentially stacked, wherein the filter set is located on the transistor layer, and wherein the transistor layer includes a plurality of parallel signal lines that are spaced from each other; a touch detection module including a cover board and a plurality of parallel touch control electrodes that are grown on a surface of the cover board and spaced from each other at a distance, wherein the plurality of touch control electrodes are perpendicular to the plurality of signal lines to form a matrix; an optical adhesive layer interposed between the at least one touch control electrode and the filter set to connect the touch detection module to the display module so that the cover board is disposed at one side of the at least one touch control electrode that is remote from the filter set; and a control process unit electrically connected with the plurality of signal lines and the plurality of touch control electrodes to sequentially output operation signals to the plurality of signal lines and detect capacitance alterations between the plurality of touch control electrodes and the plurality of signal lines, wherein the operation signals include a plurality of liquid crystal switch voltages and a plurality of location detection voltages that are generated periodically, and wherein the values of the plurality of location detection voltages are respectively smaller than those of the plurality of liquid crystal switch voltages.
