  • Publication number: 20070057294
    Abstract: An active TFT circuit structure with current scaling function is disclosed, which includes a current source, a data line, a scan line, a direct current voltage source, capacitors and four transistors, wherein the capacitors form a cascade structure. During the ON-state, the two of the transistors are turn-on based on the voltage provided by the scan line, so that the data current provided by the current source flows the data line and the transistor which is one of the opened transistors, thereby arriving an emitting light element and the transistor connected to the emitting light element. When the pixel circuit changes from ON- to OFF-state, the voltage of the node between the storage capacitors reduces due to the feed-through effect of one of storage capacitor, thereby reducing the driving current of the emitting light element. Therefore, it can be achieved the current scaling function.

  • Publication number: 20060132578
    Abstract: According to the method, a trench structure is formed in a substrate. LED arrays and driver ICs are located in the corresponding trenches. An insulating layer is formed over the substrate, the LED arrays and the driver ICs. A photolithography process forms an electrical connection structure between the LED arrays and the driver ICs. Then, a die-cutting process cuts out individual units. These units are fixed in a PCB and an electrical connection structure is formed between these units and input/output pins on the PCB.

  • Publication number: 20020091627
    Abstract: Running exerciser structure including a base seat, a running belt, a driving unit and a handle section. The base seat has a pair of substantially parallel frame bodies. A compound supporting board is disposed between the frame bodies. The compound supporting board includes a polished top board made of stainless steel and a sound-absorbent section. The polished top board is not subject to wearing and rusting caused by the sweat of a user so that the frictional resistance against the running belt is reduced. Also, the noise produced during running can be absorbed by the sound-absorbent section and is greatly lowered. The running exerciser can be durably used without frequently replacing the supporting board and the running belt.

  • Publication number: 20010005836
    Abstract: The present invention is an improved system for providing a single source system for efficiently managing the collection, tracking, reporting, and fund remittance functions of debt recovery activity between credit grantors and collection agencies. The system is provided with a central server that is networked with various credit grantor and collection agency-operated interfaces to provide improved efficiency and monitoring of the collection process. The server is programmed to format and “scrub” incoming accounts from credit grantors prior to “scoring” the same on proprietary scoring models. This allows the server to select the most appropriate collection agency for each particular account. Once the agency works the file and collects funds from the debtor, the funds are routed through the system to the credit grantor. Throughout the collection process credit grantors and collection agencies are able to monitor, audit, and update the status of each account.
