Abstract
An optical display element of one embodiment of the invention is disclosed that comprises a binary optical display element and a multiple-bit storage element to store a number of bits of a color intensity value to be displayed by the binary optical display element during a display period. Each bit is loaded from the multiple-bit storage element into the binary optical display element one or more times during the display period to achieve the color intensity value.
Claims38
An optical display element comprising:
- a binary optical display element;
- and,
- a multiple-bit storage element to store a number of bits of a color intensity value to be displayed by the binary optical display element during a display period,
- each bit loaded from the multiple-bit storage element into the binary optical display element one or more times during the display period to achieve the color intensity value,
- and the multiple-bit storage element having a number of bit storage cells equal to the number of bits of the color intensity value.
2 more elements
An optical display element comprising:
- a binary optical display element;
- and,
- means for storing a number of bits of a color intensity value to be displayed by the binary optical display element without loading the number of bits thereinto more than once during a display period, the means having a number of bit storage cells equal to the number of bits of the color intensity value.
A color optical display element comprising:
- a plurality of binary optical display elements corresponding to color components of a color to be displayed by the color optical display element;
- and,
- a plurality of multiple-bit storage elements, each multiple-bit storage element corresponding to one of the plurality of binary optical display elements and storing a number of bits of an intensity value of a different color component of the color to be displayed by the color optical display element during a display period,
- each bit stored by each multiple-bit storage element loaded from the multiple-bit storage element into one of the plurality of binary optical display elements during the display period to achieve, the color,
- wherein each bit of the number of bits of each multiple-bit storage element is loaded into one of the plurality of binary optical display elements during each interval of the display period equal to a multiple of the display period divided by two to the power of the number of bits of the intensity value minus once.
2 more elements
A display device comprising:
- a plurality of binary optical display elements;
- and,
- a multiple-bit storage element for each binary optical display elements to store a number of bits of a color intensity value of an image pixel to be displayed by the binary optical display element without loading the number of bits into the multiple-bit storage element more than once during a display period, the multiple-bit storage element having a number of bit storage cells equal to the number of bits of the color intensity value.
A method comprising:
- during each of a plurality of display period intervals of a display period,
- rotating a number of bits of a color intensity value as stored in an equal number of circularly interconnected bit storage cells among the number of storage cells so that a selected bit to be displayed by a binary optical display element in the display period interval is stored in a given bit storage cell of the number of bit storage cell;
- and,
- loading the selected bit from the selected bit storage cell into the binary optical display element to display the selected bit in the display period interval.
1 more element
A method comprising:
- providing a plurality of binary optical display elements for each of one or more of at least one color component of each of a plurality of image pixels;
- and,
- providing a multiple-bit storage element for each binary optical display element to store a number of bits of a color intensity value of the color component of the binary optical display element to be displayed by the binary optical display element, each bit loaded from the multiple-bit storage element into the binary optical display element one or more times during a display period to achieve the color intensity value, the multiple bit-storage element having a number of bit storage cells equal to the number of bits of the color intensity value.
