摘要： A display device containing an LCD light shutter front end to modulate light transmittance and a substantially flat gas discharge back end unit containing multiple gas discharge tunnels. The back end unit contains priming means to allow fast ignition of gas discharge and control means to allow independent discharge control of each discharge tunnel. The control circuit is further simplified to allow a small number of driving signals to control a large number of discharge tunnels. This backlight structure allows color light pulses to be generated in synchronization with the scanning operation of the front end unit. The combined operation of these two units can produce color images through time sequential color mixing principle. Compact and power efficient color display panels can be produced without the use of color filter in the LCD.

摘要： In a cathodoluminescent display device, spacer elements are used to provide rigid mechanical support between the face and back plates when the chamber of the device is evacuated so that thin face and back plates may be used even for large-screen displays. The spacer support includes a spacer plate having holes therein for passage of electrons between the anode and cathode where a predetermined small number of one or more pixel dots corresponds to and spatially overlaps one hole, thereby reducing crosstalk. Shadow-reducing electrodes are employed on the back plate and spacer members alongside the cathode to cause the path of electrons from the cathode to the anode to spread out in order to reduce shadows caused by the presence of the spacer members. Various configurations of the two or three sets of grid electrodes may be employed to improve resolution and focusing. A linear array of cathode filament segments is used instead of one long integral cathode wire where the ends of the segments overlap to eliminate any visible gaps caused by the end portions of the segments being at lower temperatures than intermediate portions.

摘要： In a passive liquid crystal display, frames or fields are displayed for different time periods to achieve gray scale. The voltage pulses applied to the column electrodes have substantially constant values during row scanning periods or field scanning periods to reduce power consumption. The lines of the display may be divided into odd and even fields in an interlaced configuration to suppress flicker and to further reduce power consumption by reducing frame rate.

摘要： Two separate power supplies are employed to generate electrical potentials for driving row and column electrodes of LCDs. One or more energy storage devices are preferably used together with the two power supplies for generating such potentials. In the first phase, the energy storage devices are charged and in the second phase, such devices and the power supplies are employed to generate the appropriate potentials for driving the row and column electrodes. Such schemes permit the column electrodes to be driven through a voltage range much smaller than the convention IAPT driving schemes and vastly reduces the power consumption by the driver. The total voltage dynamic range experienced by the driver circuit is comparable to the IAPT driving scheme.

摘要： A scanning flat back light source for use with light valve devices such as liquid crystal displays. It is formed by an array of parallel fluorescent tubes with fluorescent layers therein. One end of each tube is provided with an electrode and the other end connected together through a transverse chamber to form a single vacuum unit. When electrical potential is applied across electrodes in two different chambers, the two chambers and the portion of the transverse chamber connecting the two chambers form a fluorescent lamp where gas discharge produces ultraviolet light that causes a fluorescent layer on the inside walls of the tubes to produce single-color or multi-color light. During successive time intervals in the scanning operation, at least one of the tubes which are caused to emit light during one time interval is also causes to emit light during a subsequent time interval so that the charged particles present in such overlapping tube accelerate the gas discharge process during the subsequent time interval. This device is particularly suitable for portable devices such as portable computers and has high brightness and efficiency without excessive power consumption.
