    摘要: In an inline three-beam system color cathode-ray tube, there is provided an inline three-beam system color cathode-ray tube electron gun in which beam spot shapes of three electron beams on the left and right end portions of a fluorescent screen may be uniformed as much as possible and focusing voltages may be adjusted with ease and also deteriorations of beam spot shapes of three electron beams on the left and right end portions of the fluorescent screen may be alleviated and a satisfactory convergence characteristic may be obtained on the whole region of the screen. A color cathode-ray tube electron gun includes trisected focusing electrodes. Of the trisected focusing electrodes, a voltage of a waveform similar to a sawtooth synchronized with the horizontal scanning is applied to a central focusing electrode thereof, a housed resistor is connected to the central focusing electrode and two outside focusing electrodes and a voltage which results from passing the voltage Ef3 of the waveform similar to the sawtooth through the housed resistor is applied to the two outside focusing electrodes. A color cathode-ray tube electron gun includes trisected cathodes comprising a uni-potential lens and in which a voltage of a waveform synchronized with-a horizontal direction deflection and a vertical direction deflection is applied to the center electrode of the trisected electrodes.

    摘要: An in-line electron gun for a color cathode ray tube having a main lens comprised of an in-line focusing electrode and accelerating electrode, with which it is possible to easily improve an assembly precision of field-correcting electrode plates provided at the focusing electrode and accelerating electrode and having three through apertures through which the R, G, and B electron beams pass and with which it is possible to easily perform an adjustment of aberration of the main lens. The two side through apertures among the three through apertures formed in the field-correcting electrode plate provided at the focusing electrode and accelerating electrode are formed basically as circular apertures with arc shaped cut-away portions continuous with the outside of the circular apertures and concentric with the circular apertures.

    摘要: A liquid crystal display device includes: a light source section; a liquid crystal display panel including pixels and performing video display; and a drive section. The drive section performs the driving on the light source section for turning ON and OFF in synchronization with the driving of the pixels for the light-sequential writing such that, the liquid crystal display panel is selectively illuminated with the light from a lower emission region in the light source section when the pixels in an upper display region are under the driving for line-sequential writing, and such that, the liquid crystal display panel is selectively illuminated with the light from an upper emission region when the pixels in a lower display region are under the driving for line-sequential writing. A phase difference between emission periods in the upper and lower emission regions falls within a range from 90° to 150° both inclusive.
