The invention relates to a 3D touch panel, a preparation method thereof, a touch driving device, and a display device, and relates to the field of display technology. Wherein the 3D touch panel includes a display backplane and a cover that are aligned with each other; the display backplane includes a display substrate, a plurality of first touch electrodes formed on one side of the display substrate, and first wirings connecting the first touch electrodes , a plurality of spacers formed on each of the first touch electrodes; the cover includes a cover base, a plurality of second touch electrodes formed on one side of the cover base, and a second track connecting the second touch electrodes The line and the position touch layer formed on the other side of the cover substrate; the positions of the two touch electrodes are corresponding and both are located at the position of the spacers. In the present invention, the two touch electrodes used to realize touch force detection are respectively integrated on the display substrate and the cover substrate, and both are located at the position of the spacer. Combined with the position touch layer, while realizing 3D touch detection, The internal space of the display device is saved, and the space utilization rate is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a 3D touch panel, a manufacturing method thereof, a touch driving device, and a display device. Background technique [0002] A touch screen (touch screen) is also called a touch panel. With the rapid development of display technology, it has been widely used in various electronic products and pervades people's lives. The capacitive touch panel is one of the commonly used touch panels, and its principle is to use the capacitance change generated when a finger approaches the capacitive touch layer to detect the touch position. [0003] Traditional capacitive touch panels can only provide touch position detection, but with the continuous development of touch technology, more and more products use touch panels to directly complete operations on target objects. A touch force detection component is added to the touch panel to realize the touch force detection function, which...
