摘要:
The present invention provides a capacitive voltage dividing low color shift pixel circuit, which is electrically coupled to the main area (Main) of the sub pixel with a data signal line (Data) and provides a main data signal voltage thereto, and the data signal line (Data) is coupled to a common electrode line (Com) via a first capacitor (C1) and a second capacitor (C2) in series, and a routing (L) is led out between the first capacitor (C1) and the second capacitor (C2), and is electrically coupled to the sub area (Sub) and provides a sub data signal voltage thereto; with voltage dividing function of the first capacitor (C1) and the second capacitor (C2), the sub data signal voltage is different from the main data signal voltage. It can be realized to input different data signal voltages to the main area (Main) and the sub area (Sub) of the sub pixel with one data signal line (Data) to perform multi-domain display. The color shift issue of VA type liquid crystal display can be improved and the amounts of the data signal lines and the COFs are not increased.
