Liquid crystal display device and method for driving same
The occurrence of flicker is effectively suppressed particularly in a liquid crystal display device that performs low-frequency driving.Provided are a gradation-to-voltage value conversion table for converting a gradation to a voltage value, a correction value map for storing a correction value, and a voltage value-to-gradation conversion table for converting a voltage value to a gradation. A gradation of an input image signal is converted to a first voltage value, using the gradation-to-voltage value conversion table. The correction value specified in accordance with a location of a pixel to be processed is added to or subtracted from the first voltage value so that a second voltage value is obtained. The second voltage value is converted to an output gradation, using the voltage value-to-gradation conversion table. A driving video signal is applied to a source bus line, based on the output gradation.
