  • Patent number: 7646203
    Abstract: A defect detection system and related method take advantage of multilevel detection technique for detecting defects on an integrated circuit. The defect detection system utilizes an analog-to-digital converter for converting an analog sensing signal into an output code having a plurality of bits. The defect detection methods include an open test method and a short test method. The open and short test methods both include a calibrating method and a testing method individually. The calibrating method functions to determine a preset reference voltage for the analog-to-digital converter based on a predetermined code. The testing method makes use of the preset reference voltage and the predetermined code for generating the output code having a plurality of bits. The output code is then utilized to determine whether or not there are open or short defects on the integrated circuit and to classify the defects.

  • Publication number: 20080266220
    Abstract: A scan driver for a liquid crystal display (LCD) includes first and second address logic units, first and second level shifters and a decoder. The first address logic unit enables an ith first address signal among N first address signals during a Kth clock period according to a control signal, wherein the number i is equal to a remainder of K/N. The second address logic unit enables a jth second address signal among M second address signals during the Kth clock period according to the control signal, wherein the number j is equal to a quotient of K/N plus 1. The first and second level shifters respectively increase swings of the first and second address signals. When the ith first address signal and the jth second address signal are enabled, the decoder enables a (j?1)×N+i)th scan signal among M×N scan signals.
