Title:
透明圧電パネル
Document Type and Number:
Japanese Patent JP6866064
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a transparent piezoelectric panel with small variations in detection performance of touch pressure at a touch position. The transparent piezoelectric panel is provided with a first transparent electrode, a transparent piezoelectric film, and a second transparent electrode in this order, wherein when the total light transmission and the total haze value are measured at 10 locations per 1 cm square across the entire plane direction, the average value of the total light transmission is greater than or equal to 85% and the coefficient of variation is less than or equal to 30%, and the average value of the total haze value is less than or equal to 5% and the coefficient of variation is less than or equal to 30%.
