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： The present invention relates to an electrophoretic display device (1) and a method of controlling gray level transitions in an electrophoretic display device. The idea of the invention is that, in an electrophoretic device where drive signals (Dr) are applied to display device electrodes (5, 5') to effect movement of the display particles (8, 9), such that the particles correspond to image information to be displayed, a second electric signal (Ne) is applied to the display device electrodes. This second signal is arranged to decrease the ability of the particles to respond to the drive signal. By employing the second signal in accordance with the invention, more distinct optical states can be attained and the accuracy of the states becomes higher. Thus, the optical states are easier to reproduce due to a more well-defined particle control by means of the drive waveform according to the present invention.
