Abstract
A display device is driven by a driving method including a first drawing step of displaying an image by controlling a display medium on the basis of a signal from first image creation means, and a second drawing step of overwriting a handwritten image on the displayed image by controlling the display medium on the basis of a signal from second image creation means. In the first drawing step, an image is rewritten by a reset drive for resetting a display state and a writing drive for writing an image, and in the second drawing step, the writing drive is performed without effecting the reset drive.
Claims8
A driving method of a display apparatus, comprising:
- a first drawing step of displaying an image by controlling a display medium on the basis of a signal from first image creation means, and
- a second drawing step of overwriting a handwritten image on the displayed image by controlling the display medium on the basis of a signal from second image creation means,
- wherein in said first drawing step, an image is rewritten by a reset drive for resetting a display state and a writing drive for writing an image, and in said second drawing step, the writing drive is performed without effecting the reset drive.
A driving method of a display apparatus which permits handwriting input and has a memory characteristic, said driving method comprising:
- a first drawing step of displaying an image which has been memorized in advance, and
- a second drawing step of displaying a handwritten image by overwriting the displayed image with the handwritten image,
- wherein in said first display step, an image is rewritten by a reset drive for resetting a display state and a writing drive for writing an image, and in said second display step, the writing drive is performed without effecting the reset drive.
A display apparatus, which permits handwriting input and has a memory characteristic, comprising:
- detection means for detecting handwriting input, and
- drive means for effecting a first drive in which an image is rewritten by applying a writing voltage after resetting a previous display image when the handwriting input is not detected, and a second drive in which a previous display image is overwritten with a handwriting image by applying only a writing voltage without effecting resetting when the handwriting input is detected.
