Document Type and Number:
Japanese Patent JP2023018249
Kind Code:
A
Abstract:
To provide a display apparatus and an electronic apparatus capable of achieving both a force feedback function and a tactile function and having high strength.SOLUTION: A display apparatus according to the present invention comprises a display panel, a touch panel, a spacer, a tactile panel, and a piezoelectric actuator. The touch panel is arranged on the display panel and comprises a first main surface on the display panel side and a second main surface opposite to the first main surface. The tactile panel is arranged on the spacer and comprises a third main surface facing the second main surface with a gap therebetween and a fourth main surface opposite to the third main surface. The piezoelectric actuator is arranged on the third main surface and generates vibrations. Assuming that the thickness from the second main surface to the fourth main surface is a first thickness and the thickness from the second main surface to the third main surface is a second thickness, the first thickness is not less than 0.5 mm and not more than 1.5 mm, and is not less than the thickness obtained by adding 0.3 mm to the second thickness and not more than the thickness obtained by adding 1 mm to the second thickness.SELECTED DRAWING: Figure 4
