HIGH QUALITY LIQUID CRYSTAL DISPLAY PIXEL CIRCUIT

摘要

The present invention provides a high quality liquid crystal display pixel circuit, and a plurality of sub pixels arranged in array, and each sub pixel is divided into a main area (Main) and a sub area (Sub), and one data signal line, a voltage dividing unit (10) and a routing are provided in accordance with sub pixels of each column; a Nth data line (D(N)) is electrically coupled to the main areas (Main) of the sub pixels of Nth column and provides a main data signal voltage to the same, and the corresponding Nth routing (L(N)) is led out from the voltage dividing unit (10), and is electrically coupled to the sub areas (Sub) of the sub pixels of the next column, N−1 column and provides a sub data signal voltage acquired by performing voltage dividing to the main data signal voltage with the voltage dividing unit (10) to the same; polarities of the main data signal voltage provided by the Nth data signal line (D(N)) and the main data signal voltage provided by the next N+1th data signal line (D(N+1)) are opposite. The pixel circuit can diminish the color shift to reduce the flicker of the liquid crystal display panel and promote the display quality.
