Embodiment Construction

[0017] see figure 1 , is a schematic structural diagram of the first embodiment of the touch panel of the present invention. The touch panel 1 is a circular touch panel, which includes a first substrate 11 and a second substrate 12 opposite to each other at a certain distance. A first electrode 13 , a first spacer layer 16 , a positioning layer 15 , a second spacer layer 17 and a second electrode 14 are sequentially stacked between the first substrate 11 and the second substrate 12 . Wherein, the first electrode 13 is adjacent to the first substrate 11 , and the second electrode 14 is adjacent to the second substrate 12 . Both the first electrode 13 and the second electrode 14 are transparent electrodes made of indium tin oxide (ITO). The first electrode 13 has properties of softness and elastic deformation.

[0018] The positioning layer 15 includes a first sensing layer 151 , a middle base layer 152 and a second sensing layer 153 . The first sensing layer 151 is opposite...

Abstract

The invention provides a touch panel. The touch panel includes a first electrode, a plurality of first sensing lines, a plurality of second sensing lines and a second electrode which are sequentially stacked. The touch panel uses the polar coordinate system to determine the position of the touch point. Under the action of the touch force, the first electrode and the first sensing line are connected at the touch point to determine the polar coordinates of the touch point. , the second electrode is connected to a second sensing line at the touch point to determine the polar coordinates of the touch point. The touch panel has a fast response speed, and its positioning method is suitable for touch panels of various shapes.

Description

technical field [0001] The invention relates to a touch panel. Background technique [0002] In recent years, with the development of humanization and simplification of operation, touch display devices with touch panels are more and more widely used in production and life. Since the user can directly touch the touch display device with hands or other objects to input information, the user's dependence on other input devices (such as keyboard, mouse, remote controller, etc.) is reduced or even eliminated, which greatly facilitates the user's operation. [0003] At present, touch panels usually include resistive, capacitive, acoustic, infrared and other types, which are generally in the form of rectangular transparent panels, and use Cartesian coordinates to locate the touch position, and according to the touch information Take corresponding control actions. [0004] However, when the display (such as LCD) is in a shape other than a rectangle, such as a circular display used...
