Abstract:
1. A liquid crystal display (LCD), comprising: a plurality of gate lines that are parallel to each other and that each extend along a first direction; a plurality of data lines that are parallel to each other and that each extend along a second direction different from the first direction, a smallest rectangular area formed by any two adjacent gate lines together with any two adjacent data lines defining a pixel unit thereat; a gradation voltage adjusting circuit configured to receive gradation voltages from an external circuit, the gradation voltages respectively corresponding to j, j+1, k−1, and k frames, and interchange a j+1 frame gradation voltage and a k frame gradation voltage when a first voltage difference between the j frame gradation voltage and the j+1 frame gradation voltage is less than a second voltage difference between the j frame gradation voltage and a k frame gradation voltage; a memory circuit configured to store the gradation voltages received from the external circuit, wherein when the first voltage difference is less than the second voltage difference, the memory stores the gradation voltages corresponding to frames a gate driver configured for scanning the gate lines; and a data driver configured to receive the gradation voltages stored in the memory circuit and sequentially provide the gradation voltages to the data lines; wherein j, k and h are natural numbers.
