Patent ID: 8723838

Claim:
A sensor apparatus, comprising: a panel including a first transparent area and a second transparent area; an emitting device located under the panel and the emitting device emitting a light passing through the first transparent area; and a proximity sensor module located under the panel and the proximity sensor module including at least one proximity sensor which is a second proximity sensor and at least one proximity sensor which is a first proximity sensor, wherein a sensitivity of the second proximity sensor is higher than that of the first proximity sensor, and the proximity sensor module receiving the light passing through the second transparent area, wherein the light passing through the first transparent area and then reflecting from an object to passing through the second transparent area, and the panel is able to provide a touch function, wherein a maximum distance the second proximity sensor can measure the object is farther than that of the first proximity sensor, and a minimum distance the second proximity sensor can measure the object is nearer than that of the first proximity sensor; the minimum distance the first proximity sensor can measure the object is zero distance L 0 , the second proximity sensor is still able to detect the object even though the object passes through the zero distance L 0 ; wherein the touch function can be turned on or turned off depending on whether the first proximity sensor and the second proximity sensor detect the object.
