The touch panel structure includes a substrate, a plurality of first touch electrodes, a plurality of second touch electrodes, a first flexible circuit board and a pressure sensor. The first touch electrodes are arranged on the substrate and extend along the first direction. The second touch electrodes are arranged on the substrate and extend along the second direction. The first flexible circuit board includes a first part and a second part, wherein the first part extends along a first direction and is arranged on one side of the substrate, and the second part extends from an end point of the first part along a second direction, wherein the first part includes a plurality of There are a plurality of first bonding pads, the first bonding pads are connected to a part number of the second touch electrodes, the second part includes a plurality of second bonding pads, and the second bonding pads are connected to a part number of the first touch electrodes. The pressure sensor is configured on the first part of the first flexible circuit board. The touch panel structure can reduce the number of configurations of the flexible circuit board, thus making the overall volume of the touch panel structure smaller.
Description
technical field [0001] The present invention relates to a touch panel structure, in particular to a touch panel structure with a grip pressure sensing function. Background technique [0002] The mobile device can be equipped with a touch screen to display images and receive various input actions through the touch screen. Due to the convenient operation of the touch screen, the touch screen has also become one of the most common input interfaces in this generation of devices. [0003] In recent years, in addition to the above-mentioned touch screen, a squeeze-sensing device has been developed, which can be used as more gestures by the user pressing both sides of the mobile phone. However, adding the grip pressure sensing device to the mobile device will inevitably increase the number of flexible circuit boards, resulting in a reduction in the available space inside the mobile device. Contents of the invention [0004] An aspect of the present disclosure provides a touch p...
