Abstract:
A two-stage type torsion pivot hinge mainly comprising: an axle which is connected with a base and has a shaft; the shaft is mounted thereon with a bush for a spring tube, the bush forms a first and a second protrusion sheet respectively extending out of its two ends; the spring tube is fixedly connected with a supporting member and is provided with two torsion sleeves respectively on the two ends of the bush; each torsion sleeve has an axial cut and has two contact sheets extending respectively toward the two ends of the bush; the contact sheets respectively interfere with the first and the second protrusion sheets. By the function between the torsion sleeve and the bush, the pivot hinge can provide different torsion forces for the stroke of rotating the screen from its closed position to a vertical angular position and for the stroke from the vertical position to its maximum opening angular position.
Abstract:
Used in an electronic device comprising a cover panel and a base member, a slide cover mounting structure includes two hinges bilaterally mounted on the top wall of the base member, two sliding rail holders respectively connected to the pivot shafts of the hinges, two sliding rails bilaterally mounted on the bottom surface of the cover panel and respectively slidably coupled to a sliding groove on each of the sliding rail holder, two gears pivotally connected between fixed rails on the sliding rail holders, and two gear racks respectively mounted on the cover panel and meshed with the gears. Thus, the cover panel is prohibited from biasing during sliding movement, and turnable about the pivot shafts of the hinges from a horizontal position to a tilted position relative to the base member.
Abstract:
A pivot hinge includes: a fixing seat having therein a round hole from which two grooves forming an inversed “V” shape are extended downwards, the grooves include two bevel groove segments extending laterally and obliquely form the central bottom of the round hole to two different directions at the opening of the round hole, and include two vertical groove segments formed on the ends of the bevel groove segments respectively; a shaft of a rotation axle extends into the round hole; and includes: at least two mutually reversely allocated “9” shaped spring tubes each having a slipping over portion over the shaft surface, the portion is formed on its periphery a slit, a lower area of each slipping over portion has a positioning sheet extending downwards obliquely but not radially, each positioning sheet has a bottom vertical portion; the positioning sheets and the vertical portions are slipped respectively in the bevel and the vertical groove segments, an area at an upper area of each positioning sheet contacting with an upper area of a corresponding bevel groove segment forms a surface contacting fulcrum.
Abstract:
A hinge with an auxiliary bracket, the hinge is provided on one of two lateral sides of a twin-tube bracket with an auxiliary bracket, the auxiliary bracket is in an “L” or “U” shape having a pair of openings on its front side; the twin-tube bracket has on its front side a pair of protrusions being exactly engaged in the pair of openings on the front side of the auxiliary bracket. Thereby the auxiliary bracket can be engaged with the twin-tube bracket more firmly without being subjected to releasing, this renders the auxiliary bracket to really have an auxiliary supporting function.
Abstract:
In a first pair of stacked PMOS devices comprising a first PMOS device and a second PMOS device, the first pumping circuit is coupled between a gate of the first PMOS device and a P pre-driver signal. In a second pair of stacked NMOS devices comprising a first NMOS device and a second NMOS device, the second pumping circuit is coupled between a gate of the first NMOS device and an N pre-driver signal. The pumping circuits recognizing the transition from the pre-driver signals provide a voltage to the gate of the first PMOS device and of the first NMOS device so that the first PMOS and NMOS devices are turned on better. As a result, their voltage Vds peaks are suppressed to a safe level; the devices avoid hot-carrier degradations; and their lifetimes are prolonged.
Abstract:
The present invention discloses an FSC LCD enhance driving modulation method, which modulates the timing signal that controls the liquid crystal optical gate to shorten the transit delay caused by optical response delay of liquid crystal and thus increases luminous flux and improves color saturation. The present invention also controls the multi-color backlight source to sequentially emit at least two colored backlights with a dark interval therebetween. The present invention further controls the transit delay to coincide with the dark interval, whereby the latter colored backlight will not mix with the former colored backlight during the transit delay, wherefore the present invention can avoid the color deviation caused by color mixing and can present the designed colors correctly.
Abstract:
A hinge having the function of auto-shutting, it is formed on a rotation axle thereof a pair of engaging structures being of different sizes, being composed of a pair of protrusions and a pair of detents as well as being at mutual symmetrical positions separated 180° away on contact surfaces of a positioning device including a positioning block and a positioning piece, in order that a foldable electronic product connected with the hinge is able to shut automatically when in folding. And a pair of protruding stubs and recess holes are provided at the two lateral sides of the smaller protrusion and the smaller detent of the engaging structures, in order to prevent the smaller protrusion from falling into the larger detent when the foldable electronic product is opened.
Abstract:
An image data bus comprises an input port, an output port, and an image register with two ends thereof respectively coupled to the output port and the input port. The image register connects with an LCD driver. A plurality of image data buses is cascaded via using a plurality of cascading signal cables to connect the output ports and the input ports of the image data buses. Image data is sequentially transposed in a first-in-first-out way and transferred from the output port of the front-stage image data bus to the input port of the rear-stage image data bus. The present invention can facilitate flexibly constructing different-size assembled LCD billboards. Further, the present invention can reduce the cables used in wiring an assembled LCD billboard and effectively lower material cost thereof.
Abstract:
An integrated circuit structure includes first and second integrated circuit devices disposed on a interposer. Each integrated circuit device has electrostatic discharge (ESD) protection circuitry therein connected to an internal ESD bus. The first and second integrated circuit devices communicate with one another through the interposer. The interposer includes an ESD bus electrically connected to the ESD busses of the first and second integrated circuit devices for providing cross-device ESD protection for the integrated circuit devices.
Abstract:
A double sliding stability space-saving slide cover lifting structure used in an electronic device consisting of a base member and a cover panel is disclosed to include a pair hinges, a pair of sliding rail holders, a pair of bearing members, a pair of plastic slide guides, a pair of sliding rails, a pair of gears and a pair of gear racks is disclosed. The sliding rails are respectively slidably coupled to channel bars of the plastic slide guides in the bearing members, enhancing sliding stability. Further, the bearing members are prepared by a high load strength material and fixedly mounted on the sliding rail holders to support the plastic slide guides and the sliding rails, saving the space and enhancing the cover panel connection stability and preventing gear slippage and uneven bias of the cover panel.
