Problems solved by technology
[0004] In order to solve the above-mentioned problem that the traditional touch electrode structure cannot be applied to the arc-shaped touch area, the main purpose of this case is to provide a touch electrode structure, including: a first group of sensing electrode pairs, including the first sensing electrode and the second sensing electrode. The sensing electrodes are adjacent to each other through a first gap and form a first sector; and the first group of signal lines includes a first signal line and a second signal line, both of which are electrically connected to the first sensing electrode and the second signal line respectively. Two sensing electrodes

Embodiment Construction
[0026] Some typical embodiments embodying the features and advantages of the present application will be described in detail in the description in the following paragraphs. It should be understood that this case can have various changes in different aspects without departing from the scope of this case, and the descriptions and drawings therein are used for illustration in nature rather than to limit this case.
[0027] see figure 1 , which is a schematic diagram of the first embodiment of the touch electrode structure developed in this case to improve the lack of conventional technology. It is mainly completed in the form of a single conductive layer on the surface of the substrate 10. The substrate 10 can be a portable device or Display panels for wearable devices. In this embodiment, the base 10 is described as a circle, but it is not limited thereto. Depend on figure 1 It can be seen that the touch electrode structure in this case can be composed of multiple sets of sen...

The invention provides a touch electrode structure. The touch electrode structure comprises multiple inductive electrode pairs, each inductive electrode pair comprises a first inductive electrode and a second inductive electrode which are adjacent, and the first inductive electrode and the second inductive electrode are each provided with at least one cambered claw-shaped electrode. By means of the design of the touch electrode structure, the defect that traditional touch electrode structure can not be effectively switched to non-rectangular touch zones in the shapes such as circles or ellipses or sectors can be overcome.
Description
technical field [0001] The invention relates to a touch electrode structure, especially a touch electrode structure applied to a portable device or a wearable device. Background technique [0002] As smart phones and tablet computers become mainstream information commodities, touch panels (touch panels) that use touch gestures to input commands have also become popular human-machine interface control devices for users. At present, most of the mainstream portable electronic devices with touch function are equipped with rectangular touch panels. More and more, wearable devices such as watches. [0003] Traditionally, the layout of touch electrodes developed from a rectangular touch area as a starting point is mostly completed with a two-dimensional rectangular distribution. However, when this configuration is transferred to a circular or elliptical touch area, the traditional design will not be able to effectively handle the shape change of the edge area, causing problems in...
