Problems solved by technology
[0002] Touch devices are becoming more and more popular. Touch devices include touch panels. In actual use, it is found that the touch panel has the following problems: too many leads on the touch panel, which leads to the large size of the bound FPC, which increases the material cost and production difficulty.
In addition, the current client has a trend of thinning and high integration, and the existing FPC size is difficult to meet the client's needs

Embodiment Construction
[0018] In actual work, R&D personnel found that figure 1 As shown, figure 1 The touch sensing layer 10 in is disposed on the color filter substrate 18, and the touch sensing layer 10 includes a plurality of touch sensing units 11 arranged parallel to each other in the horizontal direction, and each touch sensing unit 11 includes in turn in the vertical direction Multiple driving electrodes and one sensing electrode 12, figure 1 Only four driving electrodes 13, 14, 15 and 16 are shown in, where each driving electrode is connected to a flexible printed circuit (Flexible Printed Circuit, FPC) 17 through a driving electrode lead, and the sensing electrode 12 is inductive The electrode lead is connected to FPC17. The on-cell capacitive touch screen is a single-layer multi-point mode, while for a single-layer touch panel (Touch Panel, TP), the horizontal drive electrodes are separated by vertical sensing electrodes into a section of electrode blocks, so the leads of the same node on t...

The invention discloses a touch panel and a touch device. The touch panel comprises a touch control sensing layer comprising a plurality of touch control sensing units which are distributed in the first direction, wherein each touch control sensing unit sequentially comprises a first electrode set, a second electrode set and a third electrode set; the first electrode set comprises a plurality of first electrode units which are distributed in the second direction, each first electrode unit comprises at least two first electrodes, and first electrodes of each first electrode unit are connected with different leads; the second electrode set comprises a plurality of second electrodes which are distributed in the second direction, and the second electrodes are connected with different leads; the third electrode set comprises a plurality of third electrode units which are distributed in the second direction, each third electrode unit comprises at least two third electrodes, the third electrodes of each third electrode unit are connected with different leads, and the first direction and the second direction are crossed. The touch panel and the touch device reduce the number of the leads, lower production cost and increase the production yield.
Description
Technical field [0001] The present invention relates to the field of touch technology, in particular to a touch panel and a touch device. Background technique [0002] Touch devices are currently becoming more and more popular. Touch devices include touch panels. In actual use, it is found that the touch panel has the following problems: too many leads on the touch panel, resulting in too large size of the bound FPC, which increases material cost and production difficulty. In addition, the current client has a trend of shallowness and high integration, and the existing FPC size cannot meet the needs of the client. Summary of the invention [0003] In view of this, embodiments of the present invention provide a touch panel and a touch device. [0004] An embodiment of the present invention provides a touch panel including a touch sensing layer, and the touch sensing layer includes a plurality of touch sensing units arranged along a first direction, wherein: [0005] Each of the touch...
