Patent number: 7592987Abstract: 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 through 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.Type: GrantFiled: March 2, 2006Date of Patent: September 22, 2009Assignees: Quanta Display, Inc., National Chiao Tung UniversityInventors: Pei-Ming Chen, Yen-Lin Wei, An-Chih Wang, Yen-Chung Lin, Jian-Zhi Huang, Chia-Feng Yang, Jiun-Shiau Wang, Han-Ping Shieh

Publication number: 20080239728Abstract: The light control device provides fillings in the valleys of the prism elements, be it uniformly or non-uniformly arranged, which is made of UV and/or thermal curable resins of an appropriate refractive index different from that of the prism elements. The optical performance of the original prism elements can be altered by the following approaches. First, the refractive index of the fillings can be appropriately chosen. Second, the fillings can be up to an appropriate height (but never overruns the surrounding prism elements).
