Abstract:
1. An input device for a touch panel type for a vehicle, in which the input device includes a window panel for constituting a front side of a front panel and a front board for constituting a rear side of the front panel, the input device comprising: a touch cell sensor unit composed of a plurality of touch cells for sensing a change of pulse corresponding to change of electric field and configured to input a signal; and a light emitting diode (LED) driving unit configured to provide lighting as a feedback in case of touching the touch cell, wherein each of the touch cells inputs the signal by sensing the change of the pulse corresponding to the change of electric field in case of being touched, respectively, and when Illumination (ILL) is turned off and an operating signal of corresponding key is applied through a power source for driving a control integrated circuit inside of each LED, a first LED is turned on, and when the ILL is turned on and the operating signal of corresponding key is not applied through a ILL power source of a button, a second LED is turned on, and when the ILL is turned on and the operating signal of corresponding key is applied through the ILL power source of the button, the second LED is turned off and the first LED is turned on, the first and second LED configured as different colors.
