摘要： A cathode ray tube comprising an electron source and an electron beam guidance cavity having an input aperture and an output aperture, wherein at least a part of the wall of the electron beam guidance cavity near the output aperture comprises an isolating material having a secondary emission coefficient delta 1 for cooperation with the cathode and for forming an electron source. Furthermore, the cathode ray tube comprises a first electrode which is connectable to a first voltage source for applying, in operation, an electric field with a first field strength E1 between the cathode and the output aperture. delta 1 and E1 have values, which allow electron transport through the electron beam guidance cavity. According to the invention, the cathode structure comprises means for reducing the spread of the energy distribution of the electrons leaving the exit aperture between the input of the cavity and the accelerating grid.

摘要： A light valve (1) for controlled transmission of light comprises a first (4, 5, 6) and a second (8, 9) element at least one (8, 9) of which two elements is controllably movable into optical contact with the other element (4, 5, 6). Each facing side of the elements is provided with an interference filter layer (6, 8), which interference filter layers (6, 8), when being in optical contact with each other, have a transmission for light projected onto the light valve in a wavelength range determined by the interference filter layers (6, 8), which transmission differs from the transmission in the case where the interference filter layers (6, 8) are not in optical contact with each other. Such light valves (1) are used in devices comprising a light source (3) and for displaying signals that are present in an electronic form. The light valve (1) is used to control the transmission of light emitted by the light source (3) based on signals which are present in an electronic form. When a multi-colored light source (3) is used, color filters (16B, 16G, 16R) associated with the light valves are provided in a light path so as to form a multi-colored image. Phosphors (18B, 18G, 18R) may be used instead of color filters (16B, 16G, 16R) when the light source (3) is an ultraviolet light source (3).

摘要： The display device ( 1 ) comprises a light transmitting first plate ( 2 ), a second plate ( 4 ) facing the first plate ( 2 ), a movable element ( 3 ) between the first plate ( 2 ) and the second plate ( 4 ) able to decouple light out of the first plate ( 2 ). The first plate ( 2 ) has a first surface ( 40 ) facing away from the movable element ( 3 ) and a second surface ( 14 ) facing the movable element ( 3 ), and electrodes ( 5,6,25 ) on the first plate ( 2 ), the second plate ( 4 ) and the movable element ( 3 ), able to locally bring the movable element ( 3 ) into contact with the first plate ( 2 ) by applying voltages to the electrodes ( 5,6,25 ). Including light absorption means ( 41 ), able to absorb light decoupled out of the first plate ( 2 ) by the movable element ( 3 ), and optical coupling means ( 43 ) at at least one of the first and second surface ( 40, 14 ) for having light directed into the first plate ( 2 ) via the first surface ( 40 ), reflected at the second surface ( 14 ) and directed out of the first plate ( 2 ) via the first surface ( 40 ), the display device ( 1 ) requires relatively little energy to be operated.

摘要： The display panel 21 comprises a light guide plate 2, a second plate 4 and a movable element 3 between both plates, for locally coupling light out of the light guide plate 2. Voltages applied to electrodes 5, 6 and 25 locally bring the movable element 3 into contact with the light guide plate 2 or the second plate 4. Means for reducing sticking of the movable element 3 to the plates comprise a roughness R 1 at the contact surface 14 of the light guide plate 2 facing the movable element 3, a roughness R 2 at the contact surface 15 of the movable element 3 facing the light guide plate 2, a roughness R 3 at the contact surface 16 of the second plate 4 facing the movable element 3 and a roughness R 4 at the contact surface 17 of the movable element 3 facing the second plate 4. The roughnesses R 1 and R 2 are smaller than at least one of the roughnesses R 3 and R 4. By virtue thereof, sticking is reduced and the display panel 21 requires relatively little energy to be operated.

摘要： A light valve for controlled transmission of light comprises first and second elements at least one of which is controllably movable into optical contact with the other element. Means are provided for projecting light on the first of the two elements on the side remote from the second of the two elements. Each facing side of the elements is provided with an interference filter layer, which interference filter layers, when being in optical contact with each other, have a transmission for light projected onto the light valve in a wavelength range determined by the interference filter layers. This transmission differs from the transmission that would occur in the case where the interference filter layers are not in optical contact with each other.
