Abstract:
1. An information display apparatus with proximity detection performance, the device comprising: a display device that displays image information; a sensor constituted of plural detection electrodes; and a detection resolution adjusting device that adjusts (a) detection sensitivity of the detection electrodes by controlling an output of each of the detection electrodes and (b) detection resolution by controlling a detection interval determined by a number of electrodes that contribute to the detection electrodes through activation or non-activation of the detection electrodes, the adjustment based on a distance between the sensor and an object to be contacted to any one of the detection electrodes, wherein the detection sensitivity decreases as the object approaches the sensor and the detection resolution increases as the object approaches the sensor to make the detection interval narrower in accordance with the adjustment, and wherein if no object is detected, the detection sensitivity is increased to a maximum and the detection resolution decreases to make the detection interval a maximum in accordance with the adjustment.
