Problems solved by technology

However, further improvements in touch resolution are limited in existing designs
In addition, as the number of electrodes increases, more second connecting wires are needed to transmit driving signals to them, which makes the design of wiring and driving chips more difficult, and causes the size of the bonded FPC to be too large

Embodiment Construction

[0025] Various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 2 A touch input device 100 according to an embodiment of the present invention is schematically illustrated. The touch input device 100 includes at least one electrode structure unit 110 formed in a single layer on the substrate 101 . As shown in the figure, the electrode structure unit 110 includes a first column driving electrode on the left, a second column driving electrode on the right, and a sensing electrode between the first column driving electrode and the second column driving electrode. In other words, the first column of driving electrodes, one sensing electrode and the second column of driving electrodes are arranged sequentially in the row direction.

[0027] In the electrode structure unit 110, the first row of driving electrodes and the second row of driving electrodes each include at least one first driving ele...

Abstract

The invention discloses a touch input device, which comprises a plurality of driving electrodes and a plurality of sensing electrodes formed on a first surface of a substrate. Provide improved touch input devices (eg, reduced electrode footprint or increased touch resolution, and / or reduced number of leads to drive electrodes) by: (1) multiplexing sensing electrodes in the horizontal direction; (2) Further, the driving electrodes are multiplexed in the column direction, wherein one sensing electrode multiplexed in the row direction can be further split into two adjacent sub-sensing electrodes in the row direction. Also disclosed is a touch display device, including the touch input device.

Description

technical field [0001] The present invention relates to the technical field of touch input, and more particularly to a touch input device and a touch display device. Background technique [0002] The touch panel is an input device for moving a cursor or inputting instructions using a sliding or tapping operation of a touching object (for example, a finger). For capacitive touch panels, when the user's finger approaches the touch panel, the capacitance will change. The capacitance change is detected by the touch panel itself and converted into coordinates, so as to obtain the movement of the finger and convert it into corresponding control commands. [0003] Traditional capacitive touch sensors mostly have a two-layer structure, that is, a layer of driving electrodes Tx and a layer of sensing electrodes Rx, and the cost thereof is relatively high. Recently, a single-layer touch screen sensor solution has been proposed, whose typical structure is as figure 1 shown. Multiple...
