Abstract

The invention provides a touch panel and a touch device. The touch panel is characterized in that a first electrode unit in the touch panel is arranged into a plurality of electrode branches which areradially distributed around a radiation center; the first electrode unit is wrapped by a second electrode unit; the first electrode unit is provided with electrode branches in multiple directions, and mutual capacitance can be formed between the electrode branches in each direction and the second electrode unit. When touch sliding in all directions is carried out on the touch panel, stable mutualcapacitance can be generated in all the directions. Through the setting mode, according to the mutual capacitance in each direction, the touch position can be accurately calculated, the linearity when continuous touch sliding is carried out on the touch panel is improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a touch panel and a touch device. Background technique [0002] The touch panel mainly includes resistive type, capacitive type, optical type, acoustic wave type and electromagnetic type according to its sensing method. Among them, the capacitive touch panel has become the mainstream in the current market due to its obvious advantages in response time, reliability, and durability. However, when the common capacitive touch panel is used, the detection of the touch position will be biased. Contents of the invention [0003] In order to improve the above technical problems, the present invention provides a touch panel and a touch device. [0004] The first aspect of the embodiments of the present invention provides a touch panel, including: a plurality of first electrodes and a plurality of second electrodes; each of the first electrodes includes a plurality of first ...
