[0005] However, if figure 1 The pixel design shown will suffer from many defects
When the data signal line DL j ,DL j+1 provide signals to the data signal line DL located in the j ,DL j+1 between the gate signal line and the GL i When the upper pixel area is not driven, but the adjacent pixel area below is not driven, due to the effect of capacitive coupling between the data signal line and the transparent electrode, the original undriven pixel area will also be affected by the driving of the adjacent pixel area, resulting in vertical The problem of crosstalk (vertical crosstalk). Moreover, the pixel design where the data signal line falls in the penetration area will also sacrifice the aperture ratio and reduce the penetration rate.
