  • Patent number: 8854334
    Abstract: An exemplary embodiment of touch display device includes a touch panel and a signal processing circuit. The touch panel includes a plurality of touch sensing units, and each touch sensing unit includes a touch sensing element and a coupling sensing element. The signal processing circuit is electrically connected to the touch sensing element and the coupling sensing element. The touch sensing element provides a touch signal to the signal processing circuit, the coupling sensing element provides a coupling signal to the signal processing circuit, and the signal processing circuit processes the touch signal according to the coupling signal to filter an interference signal of the touch signal. A touch display device using the touch panel is also described.

  • Patent number: 6720791
    Abstract: An LCD panel testing method. The method comprises forming jump lines in a predetermined region on the substrate between the signal lines via mask design when forming TFT LCD arrays, and thus forming a plurality of signal-line groups each with two signal lines coupled by the jump lines. Thereupon, an array tester sequentially tests two pixels corresponding to the signal lines in the signal groups. If one of the feedback signals from the signal groups does not meet a predetermined standard, it is determined that one or both pixels in the signal group are defective. The defective pixel or pixels are then identified using an electronic microscope to test two pixels at the same time. In this way, the number of probe pins and tests performed is halved. The probe pin size is also thus less restrictive due to larger probe pin intervals. Consequently, yield is greatly increased.

If one of the feedback signals from the signal groups does not meet a predetermined standard, it is determined that one or both pixels in the signal group are defective. The defective pixel or pixels are then identified using an optical apparatus such as an electronic microscope having a scope capable of testing two pixels at the same time. In this way, the number of probe pins and tests performed is halved. The probe pin size is also thus less restrictive due to larger probe pin intervals. Consequently, yield is greatly increased.
