Abstract: A grey scale is generated by modulating light in response to an information signal using an electro-optical material. An analog sample is derived from the information signal, a drive signal is generated in response to the analog sample and the drive signal is applied to the electro-optical material. The drive signal has a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a temporal duration that has a pre-determined relationship to the analog sample, and the second temporal portion is the temporal complement of the first temporal portion.

Abstract: An apparatus and a method for protecting charge storage elements from photo-induced currents in silicon integrated circuits are provided. In order to protect against photo-induced currents that are generated outside the storage node circuits themselves, an n-well guard ring is placed as closely as possible to the transistors and other elements in the storage node circuits. As a result there is a minimum of exposed silicon area in which light can produce current in areas next to the storage node circuits, and the n-well guard ring captures photo-induced currents that are generated outside the storage node circuits. In order to protect against the photo-induced currents that are generated inside the storage node circuits, an aluminum interconnect layer is placed on top of the storage node circuit, separated by an insulating layer of silicon dioxide. This creates a shield against the light and protects the storage node circuit by reflecting light away.

Abstract: The display device operates in response to an information signal and comprises analog drive circuits in a two-dimensional array of rows and columns, an analog sampling circuit that derives the analog samples from the information signal, and a sample distribution circuit. The sample distribution circuit receives the analog samples from the analog sampling circuit and distributes them to the analog drive circuits. The sample distribution circuit includes input gates corresponding to the analog drive circuits, column busses corresponding to the columns of the array, and a row selector having outputs corresponding to the rows of the array. The column busses distribute the analog samples column-wise to the analog drive circuits. The input gates connect the analog drive circuits to the column busses. Each output of the row selector is connected to control the input gates in one of the rows. The row selector sequentially opens the input gates in the rows to select the analog samples on the column busses row-wise.

Abstract: The analog drive circuit drives a pixel electrode in response to an analog sample derived from a video signal. The analog drive circuit comprises a sample selection section and a drive signal generator. The sample selection section receives and temporarily stores the analog sample during a sample load period. The drive signal generator generates a drive signal and applies the drive signal to the pixel electrode during a display period that follows the sample load period. The drive signal is composed of a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a time duration substantially proportional to the analog sample temporarily stored in the sample selection section. The second temporal portion is the temporal complement of the first temporal portion.
