Abstract: A film speaker includes at least one connecting pole, at least one piezoelectric film forming an empty cavity and an conductive layer coated on the piezoelectric film. The connecting pole is electrically connected to the conductive layer.

Abstract: An insert molded article (10) includes an insert component (12) and a molded component (14). The insert component includes a main body (121) and at least one protrusion (122) protruding outwardly from the main body. The at least one protrusion have a free end larger than an opposed other end thereof abutting against the main body in sectional area. The molded component has an inner wall (144) molded with the insert component. The inner wall has at least one latching notch (145) formed therein. The at least one protrusion of the insert component is moldingly embedded in the at least one latching notch in a snap fit engagement.

Abstract: An exemplary display device (400) includes a display module (430), an integrated power supply (410), a display control circuit (420), a safe control circuit (465), a second power supply (460), a first sensor (425), and a second sensor (435). The integrated power supply is configured to provide electric energy to the display module. The second power supply is connected to the display control circuit via the safe control circuit, and is configured to provide electric energy to the display module via the safe control circuit. The safe control circuit is configured to adjust electric energy that is provided to the display module by the second power supply. The first sensor is connected to the display control circuit, and is configured to sense ambient brightness. The second sensor is connected to the display control circuit, and is configured to sense display brightness of the display module.

Abstract: An LCD module (2) includes a frame (210) having a plurality of side walls (212) which cooperatively defining a containing space (211), one of the side walls defines a slot (213) and two rib portions (214, 215) bounding the slot, one of the rib portions is adjacent to the containing space and defines at least one gap (216) therein; a light guide plate (220) having a light incident surface, one or more optical sheets (230, 240, 250), and an LCD panel (260) disposed in the containing space; a circuit board (270) electrically connecting to the liquid crystal display panel; and at least one point light source (280) attached at the circuit board and being adjacent to the light guide plate. The point light source is received in the gap and interferentially received in the slot between the rib portions.

Abstract: An LCD module (2) includes a frame (230) having a first containing space (231) and a second containing space (232), a light guide plate (240) received in the first containing space, an LCD panel (220) disposed on the light guide plate, a rigid-flexible printed circuit board (210) electrically connecting to the LCD panel, and at least a light emitting diode (200) electrically connecting to the rigid-flexible printed circuit board. The rigid-flexible printed circuit board includes at least one rigid circuit region (211), and the light emitting diode is provided at the rigid circuit region. The rigid circuit region is received in the second containing space.
