Title:
TACTILE SENSATION PRESENTATION PANEL, TACTILE SENSATION PRESENTATION TOUCH PANEL, AND TACTILE SENSATION PRESENTATION TOUCH DISPLAY
Document Type and Number:
WIPO Patent Application WO/2021/059739
Kind Code:
A1
Abstract:
The present invention provides a tactile sensation presentation panel wherein: a tactile sensation presentation screen has tactile sensation electrodes that include a plurality of first electrodes and a plurality of second electrodes arranged alternately with intervals therebetween on a transparent insulating substrate; a first voltage signal having a first frequency is applied to those of the plurality of first electrodes located on at least a portion of the transparent insulating substrate, and a second voltage signal having a second frequency different from the first frequency is applied to those of the plurality of second electrodes located on at least a portion of the transparent insulating substrate, thereby imparting a tactile sensation to a pointing body; and a first electrostatic capacitance formed between the tactile sensation electrodes and the pointing body is calculated, and the frequency and amplitude voltage of the first and second voltage signals are adjusted on the basis of the calculated first electrostatic capacitance, thereby rendering constant a voltage according to the first electrostatic capacitance.
