Abstract:
1. A display capable of detecting at least one object, comprising: (a) a display panel for displaying information, the display panel having a display area and a peripheral portion around the display area; (b) a plurality of acoustic/ultrasonic transducers, {X (c) a processor in communication with the plurality of acoustic/ultrasonic transducers {X (d) a microcontroller coupled between the plurality of acoustic/ultrasonic transducers {X (e) an application-specific integrated circuit (ASIC) having a first port and a second port coupled to the microcontroller, and a third port coupled to each acoustic/ultrasonic transducer X wherein for each period of each of said acoustic/ultrasonic transducers X i , the first duration Δt di is from an initial time, t 0i , to a first time, t 1i , of the period, an effective time interval ΔT i is from the initial time, t 0i , to a second time, t 2i , of the period, and the second duration ΔT di is from a third time, t 3i =2ΔT i , to a fourth time, t 4i =2(ΔT i +Δt di ), of the period, wherein t 4i >t 3i >t 2i >t 1i >t 0i , wherein the first duration Δt di defines a detecting region for the at least one object to be detected in the period, and wherein the effective time interval ΔT i =(t 2i −t 0i ) determines an effective distance for the at least one object to be detected in the period.
