| 摘要 | The still image display mode includes a first period of writing the data of the image signal from the driver circuit portion into the pixel; after the first period, a second period of stopping supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion; and after the second period, a third period of restarting the supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion and writing the data of the image signal into the pixel from the driver circuit portion, so that the pixel keeps displaying a still image. A length of a period from the stop of the supply of the signal for operating the driver circuit portion to the driver circuit portion to the restart is set in accordance with a temperature of the display device. | ||

| 主权项 | 1. A method for driving a display device comprising the steps of: supplying an image signal of a still image from a display control circuit to a driver circuit portion; writing a data of the image signal from the driver circuit portion into a pixel; after writing the data of the image signal, holding the data written into the pixel by stopping a supply of a signal for operating the driver circuit portion from the display control circuit to the driver circuit portion for a period; and after the period, restarting the supply of the signal for operating the driver circuit portion from the display control circuit to the driver circuit portion to write the data of the image signal of the still image from the driver circuit portion into the pixel; wherein a length of the period from a step of stopping the supply of the signal for operating the driver circuit portion to a step of restarting the supply of the signal for operating the driver circuit portion is set in accordance with a temperature of the display device detected by a temperature detection circuit in the display device, and wherein the pixel is configured to display the still image in the period. | ||
