[0002] The self-capacitive touch panel has been widely used in the field of display devices, but under the premise of ensuring the touch resolution, there is a requirement for the size and width of the touch unit. The existing embedded self-capacitive touch panels include Most of the touch units adopt square (Block Pattern) design, and the embedded self-capacitive touch panel requires a large number of touch units
[0003] In the prior art, each touch unit is connected to the corresponding touch metal wire through a separate touch channel, and each effective touch metal wire is connected to a touch unit and a touch channel. As the size of the embedded self-capacitive touch panel increases, the number of touch units increases, which leads to a corresponding increase in the number of touch metal wires and touch channels, thereby increasing the size and cost of the embedded self-capacitive touch panel

The present application discloses an array substrate, a touch display panel and an electronic device. The array substrate comprises a touch area and a plurality of switching units; the touch area comprises a plurality of touch rows and a plurality of touch columns formed by arranging a plurality of touch units, and the touch rows comprises a plurality of odd touch rows and a plurality of even touch rows that are disposed adjacently; and two adjacent touch units in each touch column and respectively located in the odd touch row and the even touch row are connected to a same switching unit, and the switching unit drives the plurality of odd touch rows and the plurality of even touch rows within any touch time period through a control signal output by the same control signal output end. According to the technical scheme of the present application, the number of driving lines can be reduced under the premise of determining the touch position, the size of the touch display panel can be reduced, and the cost can be reduced.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an array substrate, a touch display panel and electronic equipment. Background technique [0002] The self-capacitive touch panel has been widely used in the field of display devices, but under the premise of ensuring the touch resolution, there is a requirement for the size and width of the touch unit. The existing embedded self-capacitive touch panels include Most of the touch units in the world adopt a square (Block Pattern) design, and the embedded self-capacitive touch panel requires a large number of touch units. [0003] In the prior art, each touch unit is connected to the corresponding touch metal wire through a separate touch channel, and each effective touch metal wire is connected to a touch unit and a touch channel. As the size of the embedded self-capacitive touch panel increases, the number of touch units increases, resulting in a correspond...
