Description

Electrostatic capacitance combined with touch panel

The present invention relates to a touch panel of a combination of electrostatic capacitances, and more particularly to a technique applicable to an electrostatic capacitance combined touch panel using a conductive film containing a metal nanowire as a transparent electrode.

The touch panel is a device that detects a position by touching a screen corresponding to a display area of the display device with a finger or a pen, and combines the position coordinates and the like with the display device to input to the display device. According to the operation principle of the touch panel, there are various methods such as a resistive film method, an electrostatic capacitance combined method, an infrared method, an acoustic pulse method, an ultrasonic method, and an electromagnetic induction combined method.

The touch panel of the electrostatic capacitance combining method is formed on a touch panel screen on the touch panel substrate corresponding to the display area of the display device, and is formed with a transparent electrode that detects the touched position and is patterned. A wiring circuit for taking out a position detecting signal from the transparent electrode and a wiring circuit for outputting the position detecting signal to the external detecting circuit is formed around the touch panel screen.

In general, the touch panel of the electrostatic capacity combination has the advantage of being capable of detecting the position of the touch at a high speed, and detecting the position by capturing the change in the electrostatic capacity between the fingertip and the position detecting electrode based on the finger touch. For example, in the case of detecting the XY position, there is a structure in which the XY position detecting electrodes are insulated.

In such a touch panel, a metal oxide conductor such as indium tin oxide is used as it is for the above-mentioned transparent electrode from the viewpoint of conductivity and light transmittance. However, metal oxide films are usually formed by vacuum sputtering using a sputtering method, so there is a need to form a cost. question. Further, in particular, in the case of indium tin oxide, in order to form a film excellent in conductivity and light transmittance, a high temperature condition of approximately 200 ° C is required, and the internal stress of the formed film is large and is applied to the substrate to be formed. Stress load, etc.

In place of the metal oxide film having such a problem, in recent years, a conductive film containing a metal nanowire has been known. In particular, it is known that a coating film solution contains a metal nanowire, which is applied onto a substrate by an inkjet method, a dispensing method, or a screen printing method, and dried to form a transparent conductive film.

For example, Patent Document 1 and Patent Document 2 are known as examples of the electrostatic capacitance coupling type touch panel. Further, Patent Document 3 is known as an example of a touch panel using a transparent conductor including a metal nanowire. Further, Patent Document 4 is known as an example of a conductive composition containing a metal nanowire.

However, the inventors of the present invention conducted research on the conventional electrostatic capacitance-capable touch panel including the above-mentioned Patent Documents 1 to 4, and as a result, the following cases were clarified.

For example, in the conductive film containing the metal nanowire, the metal nanowires are in contact with each other and electrically connected to each other to exhibit electrical conductivity. In this case, when the coating film solution contains a metal nanowire, a coating film is formed, and heat drying is performed to form a transparent conductive film, the film shrinks and shrinks from the time of coating to the formation of the dried film. At this time, the shape or the relative positional relationship of the metal nanowires in each of the formed films was the same, and thus the individual difference was generated. because As a result, the relative positional relationship between the metal nanowires in the film fluctuates, and the contact bonding state changes due to the film. Therefore, it is considered that there is a problem that the conductivity characteristics also fluctuate as the film is formed.

Therefore, the present invention has been made in view of the above problems, and a representative object thereof is to provide an electrostatic capacitance which realizes detection of high-quality electrostatic capacitance by using a conductive film containing a metal nanowire which suppresses variations in conductive characteristics.

Since the conductive film is not changed by film transfer, exposure, and development, a high-capacity electrostatic capacitance-capable touch panel having transparent electrodes 103 and 104 having XY position coordinates can be produced.
