Abstract

A touch display device includes a substrate, a conductive layer and a transparent layer. The conductive layer is disposed on the substrate layer, and includes a plurality of metal lines, which extend along a first direction and are insulated from one another. The transparent layer is disposed on the conductive layer, and includes a plurality of first electrode strips, which extend along the first direction and individually overlap with at least one of the metal lines in a second direction substantially perpendicular to the substrate. The first electrode strips are disposed between a plurality of second electrode strips and the metal lines. The second electrode strips extend along a third direction different from the first direction and are disposed above the transparent layer. The second electrode strips form capacitance coupling with the metal lines via the first electrode strips to perform touch sensing.

Description

technical field [0001] The present invention relates to a touch display device, its driving method and its manufacturing method, especially to a touch display device using a conductive layer of a display panel and a transparent layer disposed on the display panel as touch sensing elements, and its A driving method and a method of making the same. Background technique [0002] The traditional touch display device is formed by directly laminating the touch panel and the display panel through optical glue, so the overall thickness and weight of the panel are higher than that of a single display panel, causing a burden on the user to carry. Although the touch function has been integrated into the display panel at present, the newly added touch sensing circuit utilizes transparent electrode blocks that are not connected to each other as the driving electrodes and sensing electrodes. Generally, the transparent electrode material is indium tin oxide, and its conductivity is not hi...
