Abstract: A double-sided LCD (200) device includes an LCD panel (201) having a main-display area (208) and a sub-display area (218). A first light guide plate (204) is disposed corresponding to the main-display area. The first light guide plate has an emitting surface facing toward the main-display area, and an incident surface adjacent to the emitting surface. A first light source (205) is arranged opposite to the incident surface of the first light guide plate. A second light guide plate (214) is disposed corresponding to the sub-display area. The second light guide plate has an emitting surface facing toward the sub-display area, and an incident surface adjacent to the emitting surface. A second light source (215) is arranged opposite to the incident surface of the second light guide plate. This configuration can decrease an overall thickness of the double-sided LCD device.

Abstract: A liquid crystal display device (1) includes a liquid crystal display panel (10), a flexible printed circuit (14), and a frame assembly (16). The liquid crystal display panel includes a first substrate (102), a second substrate (104) opposite to the first substrate, and a liquid crystal layer (106) disposed between the first and second substrates. The flexible printed circuit is electrically connected to the second substrate. The frame assembly receives the liquid crystal display panel, and includes a conductive element (176) electrically connected to the flexible printed circuit. The liquid crystal display device includes the conductive element electrically connected to the grounded flexible printed circuit, which enables to conveniently prevent the liquid crystal display panel from being damaged by static electricity.

Abstract: An exemplary backlight module (5) includes a light guide plate (54) having a light incident surface (546), and a circuit board (62) disposed adjacent to the light incident surface. A pair of protrusions (544) of the light guide plate engages in a pair of fixing holes (524) of the circuit board, thereby fixing the circuit board and the light guide plate together. The backlight module may further include one or more optical films. In such case, the above-described fixing means may further include a plurality of side-blocks or a plurality of corner-blocks integrally formed on a light emitting surface of the light guide plate. The side-blocks or corner-blocks enable the optical films to be tightly held on the light guide plate without gaps therebetween.

Abstract: A backlight module (3) includes a light guide plate (2) and a light source (36). The light guide plate includes a light guide portion (20) and a frame portion (22) integrated with the light guide portion. The light source is arranged within the light guide portion. The light guide portion includes a light incident surface (240), a top surface (244) adjacent to the light incident surface, and a bottom surface (242) adjacent to the light incident surface. Each of the top and bottom surfaces may include an array of light diffusion concavities (246) or protrusions. The backlight module has a simple, reliable structure, and the cost of manufacture and assembly is reduced. In addition, the backlight module has improved light utilization.

Abstract: A reinforced flexible printed circuit board (20) includes a conductive portion (21) and a connection portion (22). The conductive portion includes a first metallic wire layer (13) having a plurality of conductive metallic wires, and two first insulation layers (24). The connection portion includes a second metallic wire layer (16) having a plurality of conductive metallic wires, two second insulation layers (17), and a reinforcement board (19) having a hand-grip portion (291). The reinforcement board is attached to one of the second insulation layers to reinforce the connection portion, and the hand-grip portion is positioned at an end of the reinforcement board so that it is convenient for workers to assemble the reinforced flexible printed circuit board to other components.

Abstract: A liquid crystal display module (60) includes a liquid crystal panel (30) and a frame (20) for holding the liquid crystal panel. The frame includes a base portion (25), four sidewalls (21, 22, 23, 24) provided on the base portion. The four sidewalls and the base portion cooperatively define a receiving space. One of the four sidewalls includes an elastic clasp (231) thereat, for elastically retaining the liquid crystal panel in the receiving space. With the configuration, a reducing cost, thickness and weightiness are obtained and the liquid crystal display module may be easily and conveniently assembled or disassembled.

Abstract: A hand tool for detaching rim from a vehicle includes a main shaft having a seat formed on a middle portion thereof and dividing the main shaft into a first section and a second section. A socket detachably mounted to a free end of the first section for driving bolts. A grip is rotatably sleeved on the second section of the main shaft for user to control the main shaft. A drive shaft pivotally and movably extends through the seat. The drive shaft has a taperingly flatted first end such the drive shaft can be used as a lever for detaching a rim cover. The drive shaft has a second end used as a stopper to prevent the drive shaft from overly extending through the seat and detaching from the main shaft during operating.

Abstract: An adjustable wrench for vehicle service includes a main shaft, a actuated shaft pivotally connected to the main shaft and a controlling unit pivotally mounted on the main shaft for selectively braking the actuated shaft. The main shaft includes a first end having a grip sleeved thereon and a second end having a first hook formed thereon and a first stub extending therefrom. The actuated shaft includes a first end pivotally mounted on the main shaft, and a second end having a second hook formed thereon and a second stub extending therefrom. The first and second hooks are provided to engaged to two stubs extending from a workpiece for detaching/mounting the workpiece. The first and second stubs are inserted into two holes in the workpiece for detaching/mounting the workpiece. The controlling unit controls an angle between the main shaft and the actuated shaft.

Abstract: An improved structure automobile engine crankcase oil drain tap plug that provides for airtight thread fastening in oil drain holes, its top side having an embedded annular magnet that attracts and collects friction-generated metal particles suspended in engine crankcase oil and its internal section having a steel ball valve capable of a predetermined range of upward and downward travel, thereby enabling the downward release and drawing out of engine oil in the crankcase, with its lowermost extremity featuring a threaded sealing ring that ensures that engine crankcase oil does not leak.
