The pressure detection and display apparatus includes a piezoelectric sensor having upper electrode, lower electrode, and a piezoelectric layer interposed between the upper electrode and the lower electrode, a polarization plate disposed under the lower electrode, and a display member disposed under the polarization plate. The piezoelectric layer is made of a retardation plate. The piezoelectric sensor and the polarization plate are arranged such that the absorption axis of the piezoelectric layer defines an angle of 20 degrees to 70 degrees relative to the slow phase axis of the polarization plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressure detection and display apparatus and electronic device","description":"A pressure detection and display apparatus can provide good visibility even if a person wears polarized sunglasses.
