Abstract: A backlight module includes a rear housing, a light guide plate and a light source. The rear housing includes a bottom wall and a side wall that are connected to each other; the bottom wall and the side wall enclose an accommodation cavity. The light guide plate is located in the accommodation cavity. The light source is located in the accommodation cavity and located between the side wall and a side surface of the light guide plate. The light source includes a circuit board and a plurality of light-emitting devices that are mounted on the circuit board. A surface of the circuit board away from the plurality of light-emitting devices faces the side wall, and light-emitting surfaces of the plurality of light-emitting devices face the side surface of the light guide plate.

Abstract: A gesture recognition method, apparatus and system based on coupling capacitance, which are configured to solve the technical problem in the prior art of it not being possible to recognize a complex gesture due to the fact that the coordinates of a manipulation body on a three-dimensional plane cannot be determined.

Abstract: The present disclosure relates to a sample and an evaluation method for measuring galvanic corrosion between a conductive coating and a protected substrate. A micropore insulating layer is arranged between the conductive coating and the substrate, the micropore insulating layer is composed of an insulating material and contains a micropore structure, the micropore structure can form an ion pathway on the surfaces of the conductive coating and the substrate after being filled with a conductive medium, and the substrate and the conductive coating are both connected with an independent leading wire. The sample of the present disclosure can evaluate galvanic corrosion between a conductive coating and other conductive materials more fully.
