DISPLAY ACTIVATED BY THE PRESENCE OF A USER |
摘要 |
<p>A display, typically an electroluminescent display, of the type having both an activated, "on", state and an inactivated, "off', state, and being switchable between the two, which display incorporates a capacitance sensor, able to detect the near presence of a user, together with means able to utilise the output of this sensor to effect activation of the display accordingly. Preferably, the capacitance sensor comprises a pair of electrodes, one of which may be a front electrode of the electroluminescent display. The capacitance may be sensed by determining the time taken to charge a capacitance; the capacitance may be charged at two or more rates so as to decrease the time taken to measure the capacitance and so reduce the energy consumed.</p> |
