摘要： The present invention relates to a method of generating an image having a desired brightness, which image is generated by means of a device provided with at least one light source, at least one electro-optical light modulation panel and at least one light-control device. The light from the light source is converted into an image having a desired brightness via at least the electro-optical light modulation panel and the light-control device. The image to be projected is analyzed in a regulator, whereafter the electro-optical light modulation panel and the light-control device are driven, while a too bright image is generated by means of the electro-optical light modulation panel, which image is converted by means of the light-control device into an image having a desired brightness and a desired contrast.

摘要： Such a device comprises display elements (RC) arranged, for example, in matrix form in rows and columns with, each display element comprising a first (E1) and a second electrode (E2) and an intermediate, movable, third electrode (E3). The first electrode (E1) is used in common by the elements (RC) with, the second electrode (E2) forming part of a strip-shaped row electrode and the third electrodes (E3) having an electrical through-connection in the column direction. Depending on the polarities of information pulses applied to the electrodes by a control voltage source, the third electrode is positioned adjacent the first or second electrode to achieve a bright or a dark picture element on display. With picture element-selective drive by a row selection with, a change being made for the selected picture element from the bright to the dark state, a non-energized state occurs at the other bright and dark picture elements in the column. To counteract the possibility of picture disturbance, a pulse (CT2) is simultaneously applied, in addition to the information pulses (CT1), to each electrode with a polarity which is the same for the first and the second electrodes and is the opposite for the third electrode. This results in a reset with a memory state.

摘要： A presentation system comprising an image projection screen and an overhead projector is described. The overhead projector comprises an illumination system, a support for supporting an image record carrier and a projection head for projecting the image present in the image record carrier on the image projection screen. The image projection screen is a polarizing screen which transmits radiation having a well-defined direction of transmission polarization, and the overhead projector is adapted to supply light having this direction of polarization. In this way, the quantity of radiation used for forming the image is considerably increased and substantially half the quantity of ambient light incident on the screen is suppressed, so that images having a considerably enhanced contrast and brightness are obtained.
