Title: ELECTRONIC DEVICE AND TERMINAL
Abstract:
An electronic device having a pressure sensor. The electronic device comprises an OLED display screen (702), a foam (704) and a film (706). The foam (704) is located below the OLED display screen (702), and the film (706) is located below the foam (704); a plurality of electrical bridge circuits (708) are arranged on the film (706), and each of the electrical bridge circuits comprises a first branch and a second branch connected in parallel, wherein the first branch comprises a first resistor and a third resistor connected in series, and the second branch comprises a second resistor and a fourth resistor connected in series; the plurality of electrical bridge circuits (708) are located on the same surface of the film (706); and at least one resistor of the four resistors is bonded to the foam (704), and at least one resistor is not bonded to the foam (704), wherein the resistor bonded to the foam (704) is made of a first material, and a strain sensitivity coefficient of the first material is greater than 100; and a film region where the resistor bonded to the foam (704) is located covers a second material, and a resistor not bonded to the foam (704) does not cover the second material, the Young's modulus of the second material being greater than 30.
