Abstract
When an area to be rewritten includes a first area including a character and a second area including an image object, a control unit outputs, to a controller, a display update instruction and information indicating the second area. Upon acquisition of the instruction and the information indicating the second area, first, the controller updates the first area and the second area by a first method. Next, the controller updates the second area by a second method that requires a longer updating time than the first method.
Claims8
A display apparatus comprising:
- an updating unit that updates a first area by a first method, and updates a second area by a second method, the first area being at least a portion of a display area of a display unit, and the second area being a portion of the display area,
- wherein the number of gray levels that can be expressed by the first method is N, where N denotes an integer no less than 2 and less than M,
- the number of gray levels that can be expressed by the second method is M, where M denotes an integer no less than 3, and
- the speed of the updating by the first method is greater than the speed of the updating by the second method.
A display method comprising:
- updating a first area by a first method, and updating a second area by a second method, the first area being at least a portion of a display area of a display unit, and the second area being a portion of the display area,
- wherein the number of gray levels that can be expressed by the first method is N, where N denotes an integer no less than 2 and less than M,
- the number of gray levels that can be expressed by the second method is M, where M denotes an integer no less than 3, and
- the speed of the updating by the first method is greater than the speed of the updating by the second method.
A display method for the use by a display apparatus with a display area having memory, comprising:
- updating a first area according to a first waveform during 1st to mth frame periods, the first area including an image object, and the first waveform being a waveform according to which a first number of gray levels can be expressed;
- and
- updating a second area according to a second waveform during 1st to nth frame periods, where n is less than m, the second area including no image object, and the second waveform being a waveform according to which a second number of gray levels can be expressed, the second number being smaller than the first number.
