Description

TOUCH PANEL {TOUCH PANEL}

The present invention relates to a touch panel, and more particularly, to a touch panel having a single-layer structure.

As the kinds of electronic devices to be encountered in everyday life are gradually diversified and the function of each electronic device becomes more sophisticated and complicated, there is a need for a user interface that can be easily learned and intuitively operated by the user. A touch sensing device has been attracting attention as an input device capable of satisfying such a requirement and has already been widely applied to various electronic devices.

A touch sensing device that recognizes a user's screen touch or gesture as input information is classified into a resistance film type, a capacitive type, an ultrasonic type, and an infrared type depending on the operation type. In the dual capacitance type, It has attracted much attention because of ease.

In such a capacitance type touch panel, it is important to structure the touch panel to more accurately detect the change in capacitance. The touch panel may be of a two-layer structure, wherein the touch sensor includes a plurality of drive electrode traces intersecting a plurality of receiving electrode traces (e.g., traces extending in the X-axis direction) Y-axis direction traces), and the drive and receiving electrode traces are separated by a dielectric material such as PET, Glass, or the like.

However, the touch panel, which includes the drive and receiving electrode traces, respectively formed in the lower and upper layers of the two-layer structure, can be expensive to manufacture and can be thickened. This is due to the process and structure of bonding the electrode layers of the two-layer structure.

Accordingly, a touch panel having coplanar single layer touch sensors fabricated on a single side of a single layer of a substrate of a touch panel has been proposed.

On the other hand, if there are many wires in the single layer touch sensor, it is difficult to find linearity and accuracy in touch due to an increase in dead zone which operates in a touch-free area. In the single-layer touch panel, the transmitting electrodes arranged in the column direction and the receiving electrodes adjacent to the transmitting electrodes are arranged.

As the number of receiving electrodes increases, the number of connection wirings connected to the receiving electrodes and connecting to the external touch recognition chip also increases. When the number of the connection wirings increases, a region where connection wirings are formed between the reception electrodes arranged in the row direction and the transmission electrodes adjacent to the reception electrodes increases, thereby increasing the dead zone. Further, if the number of connection wirings increases, the number of pads of the touch recognition chip also increases.

Therefore, since two receiving electrodes (e.g., left-receiving electrode and right-receiving electrode) correspond to one transmitting electrode, the number of connecting wirings required to connect the transmitting electrode can be reduced. In addition, since two receiving electrodes correspond to one transmitting electrode, the time required for scanning the entire touch panel can be reduced.

Since the transmission lines (for example, the left-transmission line and the right-transmission line) are disposed on both sides of one reception line, the boundary conditions can be made uniform as compared with the touch panel in which the transmission lines are disposed only on one side of the reception line. Therefore, the sensing efficiency of the touch panel can also be improved.

Further, two left-receiving electrodes (for example, left-receiving electrodes and right-receiving electrodes) spaced apart from each other by a predetermined distance between the left-transmitting electrodes of the left- The number of connection lines can be reduced as compared with a touch panel having one receiving electrode corresponding to one transmitting electrode. Accordingly, as the number of wirings increases, the dead zone operating in the touch-sensitive area can be reduced, and the effective touch area can be increased. In addition, since the number of connection wirings is reduced, the number of pads of the touch recognition chip can be reduced.

The capacitance sensing circuit calculates touch coordinates based on the sensing signals.

When a touch occurs at a specific position, the voltage level of the sensing signal detected at the left-receiving electrode corresponding to the position may be relatively lower than the voltage level of the sensing signal detected at the other left-receiving electrodes. Therefore, the position corresponding to the left-receiving electrode corresponding to the relatively low voltage level can be recognized as the touch coordinates.
