ABSTRACT:
An exemplary liquid crystal display (100) includes gate lines (122), and data lines (123) cooperatively defining pixel units. Each pixel unit includes a first thin film transistor (TFT) (125), a second TFT (126), a first pixel electrode (127), and a second pixel electrode (128). Gate electrodes of the two TFTs are connected to one of the gate lines. A source electrode of the first TFT is connected to one of the data lines. A drain electrode of the first TFT is connected to the first pixel electrode. A source electrode of the second TFT is connected to the first pixel electrode. A drain electrode of the second TFT is connected to the second pixel electrode. A channel width/length ratio of the second TFT is such that a voltage of the drain electrode thereof is less than a voltage of the source electrode thereof when the second TFT is switched on.
