摘要： In a predetermined period (one frame or one subframe), a backlight is lighted between the middle point in time in first data writing scanning and the middle point in time in second data writing scanning for each lighting region provided by dividing the backlight into four regions. When the time required for data writing scanning is set equal to 50% of the predetermined period, the ratio (panel on rate) of the time when a liquid crystal panel is in transmitting state to the time the backlight is lighted is as high as 93.8%. The ratio of luminance gradient (luminance in the center of display area/luminance at the end of display area) is as low as 1.14. When the backlight is lighted while being divided into ten regions, the panel on rate can be increased as high as 97.5% and the luminance gradient can be decreased as low as 1.05.

摘要： A liquid crystal display configured by stacking a plurality of liquid crystal panels displays an image by controlling the light transmittance with application of a voltage to each of the liquid crystal panels. While a voltage is being applied to the liquid crystal of one liquid crystal panel, the voltage applied to the liquid crystal of the other liquid crystal panels is a non-display voltage. No images are displayed simultaneously on two or more stacked liquid crystal panels. In a liquid crystal panel to which no voltage is applied not to display any image, the longitudinal direction of liquid crystal molecules either is parallel to the direction of the polarizing axis of a polarizing plate or is orthogonal to the polarizing axis, which has no influence on the overall birefringence. Therefore, the overall voltage-to-transmitted light intensity characteristic is the sum of the voltage-to-transmitted light intensity characteristics of all the liquid crystal panels.

摘要： The plasma display panel production process includes the formation of several blocking ribs (29) each having an elongate flat configuration. These are aligned in the same direction in a display region, and are formed in the following stages. A cutting mask (61) is formed with a mask design corresponding to the ribs, in a suitable material for the ribs. Parts of this layer is lifted by projection of a cutting medium on to the layer. The design is thus formed such that there are several elongate parts (610-613) corresponding to the blocking ribs, each crossing the display zone and reaching from outside this zone. The spacing of the adjacent ends parts of two elongate ribs is less than the spacing of the same ribs within the display region.

摘要： A plasma display panel has a first substrate (20), a plurality of address electrodes (A1,A2,A3) disposed on the first substrate, a first dielectric layer (22) disposed on the first substrate in covering relation to the address electrodes, a second substrate (10), a plurality of scan electrodes (13) disposed on the second substrate in a direction transverse to the address electrodes, a second dielectric layer (14) disposed on the second substrate in covering relation to the scan electrodes. The first substrate and the second substrate are disposed in confronting relation to each other with discharge spaces defined therebetween. The first dielectric layer (22) contains electrically conductive particles (30) mixed therewith. The electrically conductive particles make the first dielectric layer electrically conductive in its transverse direction to allow charges stored on the first dielectric layer to leak to the address electrodes for thereby reducing the frequency of random discharges.

摘要： A charged particle beam deflector has a simple structure for providing a uniform potential distribution over each blanking aperture. The deflector is easy to operate, and stabilizes the shape of a charged particle beam component passing through each blanking aperture even with a low deflection voltage. A pair of deflecting electrodes (10,11) are arranged on opposing inner walls of each blanking aperture (1). A voltage applied to the deflecting electrodes is controlled to correctly deflect the charged particle beam component passing through the blanking aperture. A pair of resistance films (12,13) are arranged on the other opposing inner walls of the blanking aperture, to connect both sides of the deflecting electrodes. The deflector may employ patterned beam generating apertures. A pair of deflecting electrodes are formed on opposing inner walls of each of the apertures. A voltage applied to the deflecting electrodes is controlled to correctly deflect a charged particle beam component passing through the aperture.

摘要： A pattern is formed on a substrate 1 by a lift-off process comprising depositing a film-forming material 3 from above a mask 5m formed on the substrate so as to form a film in regions other than the mask, wherein the film formation is carried out while directing an ion beam IB towards the mask. The ion beam inhibits the effective gradual lateral expansion of the mask that otherwise occurs owing to deposition on the edge of the mask. An electronic device such as a micro field emission cathode 2 or a planar multilayer circuit structure can be effectively formed using the process.

摘要： A voltage corresponding to desired image data is applied to a ferroelectric liquid crystal having a spontaneous polarization at a predetermined cycle to rewrite the displayed image (period A), and then, all voltages applied to the ferroelectric liquid crystal are removed (timing C) to retain the displayed image before the removal (period B). A gate selection period (voltage application period to the ferroelectric liquid crystal) t2 before stopping the voltage application is set longer than a gate selection period (voltage application period to the ferroelectric liquid crystal) t1 in the normal display. Increasing the voltage application period to the ferroelectric liquid crystal provides a sufficient response of the liquid crystal during the gate selection period, thereby realizing high memory ability.
