Electronic device and terminal
An electronic device includes: a foam is located below an OLED display, and a film is located below the foam. Multiple bridge circuits are disposed on the film. Each bridge circuit includes two parallel branches. A first branch includes a first and a third resistor. A second branch includes a second and a fourth resistor. At least one of the four resistors is bonded to the foam. At least one resistor is not bonded to the foam. The resistor that is bonded to the foam is made from a first material. A strain sensitivity coefficient of the first material is greater than 100. A film area in which the resistor that is bonded to the foam is located is covered by a second material. A Young's modulus of the second material is greater than 30.
