Abstract: There is provided a structure to improve BSI global shutter efficiency. In a sensor pixel circuit, at least one strong electric field is formed at the position of a floating diffusion region to accordingly have the effect of shielding the floating diffusion region. Or, the semiconductor material from the floating diffusion node toward a light incident direction is removed in the manufacturing process such that a depletion region cannot be formed in this direction. Or, a reflection layer or a photoresist layer is formed in the light incident direction to block the light. In these ways, charges generated by the undesired noises are reduced, and noise charges are difficult to reach the floating diffusion region thereby improving the shutter efficiency.

Abstract: There is provided a capacitive communication system including an object and a capacitive touch panel. The object includes a plurality of induction conductors configured to have different potential distributions at different time intervals by modulating respective potentials thereof. The capacitive touch panel includes a plurality of sensing electrodes configured to form a coupling electric field with the induction conductors to detect the different potential distributions at the different time intervals. When the different potential distributions match a predetermined agreement between the object and the capacitive touch panel, a near field communication is formed between the object and the capacitive touch panel.

Abstract: There is provided a displacement detection device including a light source, an image sensor and a processing unit. The light source provides light to a finger with a light source parameter. The image sensor receives reflected light from the finger, outputs valid images when the light source is being turned on and outputs dark images when the light source is being turned off. The processing unit determines a contact status according to one of the dark images and one of the valid images, and calculates a displacement according to two of the valid images to accordingly adjust the light source parameter.
