A detection signal A1 of the PD1 when the LED1 emits light, a detection signal A2 of the PD1 when the LED2 emits light, a detection signal A3 of the PD2 when the LED3 emits light, and a detection signal A4 of the PD2 when the LED4 emits light are used to estimate a reflection generation position in the left-right direction, and a threshold Th is set such that the threshold Th increases when the reflection generation position is on the left side, which is a driver's seat side. If the maximum value of A1, A2, A3, and A4 exceeds the threshold Th, the approach of the user's hand is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Proximity detection device to detect a user's approach to a display surface comprising a sensitivity setting unit","description":"Four infrared LEDs and two photodiodes PD are arranged below a lower side of a display surface in the order of an LED1, a PD1, an LED2, an LED3, a PD2, and an LED4.
