A method for displaying a moving image on a display, such that all pixel lines of the display are addressed in each case during image periods for displaying image information, and a backlight for displaying the image information backlights the pixel lines. The display of moving images is enhanced by the fact that the pixel addresses remain unchanged during a first image period and a second image period, following the first image period, for displaying the same image information, and after the first image period, the backlight backlights the pixel lines following a waiting period.

Method for displaying a moving image on a display

The aim of the invention is to largely prevent certain influences from distributing the luminance of an image that can be reproduced on a panel of a flat screen. To this end, light-permeable parts are arranged between a sensor and a back light illuminating the panel from the rear, the ageing and/or temperature properties of said light-permeable parts essentially corresponding to those of the light-permeable parts of the panel.

Arrangement having a flat screen panel illuminated with a back light that compensates for changes in luminance of the panel

A method and an arrangement for optimizing the luminance characteristic curve for a display system using a lookup table. Digitized video levels are supplied to this lookup table and are optimized using correction values stored in the lookup table. With suitable means, the luminance characteristic curve can be easily adapted to standards and/or custom specifications. The memory requirement is low, since it is not necessary to provide different lookup tables for different ambient luminosities or selected reproduction models (curves).

Method and arrangement for optimizing a luminance characteristic curve

The invention is directed to an extremely low-capacitance device for shaping an electron beam. The device is based on a ceramic body having a monolithic multi-layer structure. The manufacture of the ceramic body ensues with the assistance of LTCC technology, whereby this method is designationally modified. The body is constructed of pre-sintered ceramic layers whose lateral shrinkage is suppressed. The through apertures of the electrodes for the electron beam are thus arranged exactly coaxially, and the tolerances of the electrode dimensions are decoupled from the shrinkage during sintering. The electron beam of an electron gun is focused and the intensity thereof is modulated with the assistance of such a device.

Device for shaping an electron beam, method for producing said device and use thereof

In order to improve the definition and the breakdown behavior in a tube neck ( ) that includes an anode cylinder ( ) and a focusing cylinder ( ), the tube neck ( ) is made of a non-conductive material, particularly a ceramic. The inner surface of the anode cylinder ( ) and the inner surface and the outer surface of the focusing cylinder ( ) are coated with an electrically conductive material ( ).

Tube neck for cathode ray tube

A cathode ray tube is described having at least one electron gun including a cathode, a control grid, and a focusing unit, and a strip made of electrically conductive material applied to the cathode ray tube in parallel to the outer coating of the tube and connected to ground potential. Means and measures are provided to eliminate harmful effects of high-voltage sparkovers. The cathode ray tube may be is used, for example, in monitors.
