Problems solved by technology

[0010] However, when a conductive shielding member is arranged near the driving electrodes and the detecting electrodes, the sensitivity of the detecting electrodes decreases due to the influence of the electrostatic capacity formed between the shielding member, the driving electrodes and the detecting electrodes, so the output level of the detecting electrodes Decrease, not preferable from the viewpoint of improving position detection accuracy

Embodiment Construction

[0067] Hereinafter, a capacitive touch panel input device (hereinafter also simply referred to as a touch panel input device) 10 according to a first embodiment of the present invention will be described with reference to the drawings. In addition, in the drawings, in order to facilitate understanding of the structure of the touch panel input device 10, the size and thickness of components are appropriately changed.

[0068] figure 1 The front side of the compartment of the vehicle is partially shown. The touch panel input device 10 has a function as an input device for the driver to operate a navigation device, an air conditioner, an audio device, and the like. Therefore, the touch screen input device 10 is fixed at a position that is easy for the driver to operate, such as an appropriate position from the instrument panel 12 to the center console.

[0069] The touch panel input device 10 has a case 15 made of a translucent resin such as transparent or translucent, and a pa...

Abstract

The electrostatic capacitive touch panel input device (10,100) has a plate element (14) with an upper surface which serves as an actuating surface of an actuating area. An electrode substrate carries a drift electrode and a detection electrode. A conductive shielding element is provided in the input device.

Description

technical field [0001] The invention relates to an electrostatic capacitive touch screen input device for inputting commands to external equipment according to the touch position of an object. Background technique [0002] Capacitive touch panel input devices are widely used, for example, as input devices for personal computers, and in recent years, are also used as input devices for car navigation systems and the like. [0003] The capacitive touch panel input device has a panel member, and an electrode group is arranged on the back side of the panel member. The electrode group includes, for example, X electrodes and Y electrodes as drive electrodes, and detection electrodes, and the drive electrodes and detection electrodes are jointly or separately supported by a film substrate. [0004] In addition, a printed board is arranged on the back side of the film substrate, and a control circuit for detecting the position of an object in contact with the panel member is provide...
