Kind Code:
A1
Abstract:
In order to favorably suppress a decrease in brightness and a decrease in gradation characteristics while reducing unevenness in a display panel, disclosed is a driving method that is for a liquid crystal panel (40) containing a first display region (42) including the center and a second display region (44) around the periphery thereof, and that contains the following steps: (1) Image data for displaying each display region are supplied to each respective display region using a supply circuit (12). (2) When the supply circuit (12) supplies the image data, only the image data supplied to the second display region (44) are corrected in a first correction circuit (20). By means of this driving method, the image data supplied to the second display region (44) is corrected, and the image data supplied to the first display region (42) is not corrected, and so it is possible to favorably suppress a decrease in brightness and a decrease in gradation characteristics while reducing unevenness in the liquid crystal panel (40).
