Abstract: A display panel including a circuit board, a plurality of bonding pads, a plurality of light emitting devices, and a plurality of solder patterns is provided. The bonding pads are disposed on the circuit board, and each includes a first metal layer and a second metal layer. The second metal layer is located between the first metal layer and the circuit board. The first metal layer includes an opening overlapping the second metal layer. A material of the first metal layer is different from a material of the second metal layer. The light emitting devices are electrically bonded to the bonding pads. Each of the solder patterns electrically connects one of the light emitting devices and one of the bonding pads. The solder patterns each contact the second metal layer through the opening of the first metal layer of one of the bonding pads to form a eutectic bonding.

Abstract: The invention provides an apparatus and method for simulating a mold cooling process for injection molding. The mold includes a moldbase and a cavity; the method comprises the steps of creating a plurality of cavity meshes for the cavity, automatically creating a plurality of uniform or adaptive moldbase meshes for the moldbase, and determining the relationship between the cavity meshes and the moldbase meshes. Based on the relationship, a numerical method is applied to calculate the temperature distributions of the cavity and moldbase in the mold cooling process.

Abstract: The present invention is related to a liquid crystal display element and driving method therefor, particularly to a high image rate supertwisted nematic liquid crystal display elements and driving method therefor. By means of a newly introduced crystal formula, a reduced spacing distance between the first and second substrates, an enlarged pretilt angle of alignment layer, and an accelerated frame rate (frame rate: the number of frames displayed per second) of the driving signal, high response rate display is obtained, and thus image retention and flicker are not showed in the liquid crystal display element, so as to display the dynamic image with the effect of high image quality and fast response time.

Abstract: A steering lock with a lock body having an attached extensible member for adjusting the distance between two locking rods which are connected in parallel through a telescopic tube to form a shackle. The shackle can be extended when clearance is required, and is coupled with a pair of hook-shaped fastening rods which are connected in parallel through another telescopic tube for fastening to the steering wheel. When a lock barrel of the lock body is rotated to a locking position, the first and second latches inside the lock body lock up the locking bars and the extensible member. Two protective cover boards are bilaterally attached to the lock body to prevent insertion of a tool to cut the second latch and prevent injury to fingers during the locking and unlocking operation.
