Addressing Modes
Each sub-pixel of a display devices must be selected (addressed) in order to be energized in a controlled way.
| Addressing modes (selection of picture elements) | |
|---|---|
| direct addressing each individual picture element has electrical connections to the driving electronics. |
multiplexed addressing several picture elements have common electrical connections to the driving electronics, e. g.. row and column electrodes when the picture elements are arranged in a two dimensional matrix. |
| active matrix addressing active electronic elements added in order to improve selection of picture elements.
|
passive matrix addressing the nonlinearity of the display effect (e.g. LCD, LED)is used to realize the addressing of individual pixels in multiplex addressing. In this mode only a quite limited number of lines can be addressed. In the case of (STN-)LCDs this maximum is at ~240, but at the expense of a considerable reduction of contrast. |
| The matrix of active electronic elements can used in transmissive mode of operation (high transmittance required) or a non-transparent active matrix can be used for reflective LCDs (e.g. liquid crystal on silicon (LCOS)).| | |

Famous quotes containing the words addressing and/or modes:
“He took up his pen, which seemed to parch like a martyr in his hand. He began to write, nevertheless, addressing the nine-and-ninety lies of the moment he hoped with for a night of saloperie at the side of the twisted strumpet, Fiction, who lasciviously rolled her eyes at him, hiked up her skirt, and beckoned him on.”
—Alexander Theroux (b. 1940)
“In the final analysis, “style” is art. And art is nothing more or less than various modes of stylized, dehumanized representation.”
—Susan Sontag (b. 1933)
