Abstract: A wiring structure of a liquid crystal display device and a liquid crystal display device are disclosed. The wiring structure of the liquid crystal display device includes a substrate, plural electrical elements, and plural wirings. The electrical elements are disposed on the substrate to generate plural electrical signals. The wirings are coupled to the electrical elements to transmit the electrical signals. The wirings include inner wirings and an outermost peripheral wiring. The outermost peripheral wiring and the inner wirings have different wiring patterns. Each of the electrical elements is positioned at a side of the outermost peripheral wiring facing the center of the substrate. After the liquid crystal display device is cut and polished, by distinguishing the wiring patterns of both the outermost peripheral wiring and the inner wirings, the existence of the outermost peripheral wiring shows that the outermost peripheral wiring is not polished and removed.

Abstract: An LCD includes a first pixel electrode coupled to a first scan line and a data line, and a second pixel electrode coupled to a second scan line and the data line. A first and a second storage capacitor electrode lines are at two sides of the data line and across the scan lines. A first storage capacitor electrode extension line is extended out of the first storage capacitor electrode line and toward the data line, and a second storage capacitor electrode extension line is extended out of the second storage capacitor electrode line and toward the data line. The first pixel electrode and second pixel electrode partly overlap the first and the second storage capacitor electrode extension lines, respectively. Since the storage capacitor electrode line and the scan line is formed on different metal layer, a gap between the storage capacitor electrode line and the scan line is shortened.

Therefore, a problem of output signals being affected due to the polished and removed wirings can be decreased.

Abstract: A gain compensation circuit comprises a first amplifier, a second amplifier, a filter, a first attenuator, a second attenuator and a third attenuator. The first amplifier is configured to amplify an input signal of the microwave signal processor. The filter is disposed between the first and second amplifiers. The first attenuator is disposed between the first amplifier and the filter for reducing return loss of the microwave signal processor. The second attenuator is disposed between the second amplifier and the filter for reducing return loss of the microwave signal processor. The third attenuator is electrically connected to the output of the second amplifier for reducing noise figure of the microwave signal processor and providing first and second gain compensations. The first gain compensation keeps the gain of the microwave signal processor constant under various temperatures, and the second gain compensation adjusts a nominal gain of the microwave signal processor.
