    摘要： The present invention relates to a substrate with a substrate test circuit. In an embodiment, by making the length of the wiring from a first data-line-test input terminal to a first panel equal to that of the wiring from a second data-line-test input terminal to the first panel, the input resistances between two test input terminals of a first data-line-test line and the first panel are identical, and thus when a data line of the first panel is detected, the voltage drops of test signals inputted from the two test input terminals are the same, and the test signals actually loaded to the first panel are the same and the detecting abilities are identical.

    摘要： The present invention relates to a substrate testing circuit comprising a testing bus and a testing signal terminal connected to the testing bus, a signal line to be tested in the substrate being connected to the testing bus via a signal connecting terminal, wherein a plurality of signal access terminals are provided on the testing bus; one testing branch is connected between each the signal access terminal and the testing signal terminal; and resistance values of the testing branches are the same. By means of the present invention, since a plurality of signal access terminals are introduced and the testing branches with the same resistance are added so that input resistances and impedances of testing signals across the display screen are substantially identical without making changes to process flow and device hardware structure, input resistances and impedances of respective signal lines are well averaged, thereby no obvious regional attenuation occurs in the testing signals within the pixel area to be tested irrespective of limitation in size of panel, so as to realize tests for panels with greater sizes.

    摘要： The present invention relates to a low pass filter incorporating coupled inductors to enhance stop band attenuation. In one embodiment, the coupled inductors are provided along with various capacitors to provide for superior performance within a smaller surface area of a semiconductor or ceramic integrated device. In a further specific embodiment, the capacitors are formed on an integrated device within an area on which entirely intertwined inductors are formed. In another embodiment, at least one further pair of coupled inductors is included to create additional frequency attenuation notches, as well as a wide stop-band.
