摘要:
A plasma-addressed display device which achieves both of suppression of abnormal discharge and stabilization of a discharge potential of a plasma cell. The plasma-addressed display device comprises a display cell having a plurality of data electrodes therein, a plasma cell associated with the display cell and having a plurality of addressing channels in a direction perpendicular to the data electrodes. Each channel has a pair of electrodes which comprise a coated electrode coated with a dielectric material layer and an exposed electrode. A driving circuit applies data voltages to the respective data electrodes on the basis of a reference potential, and a scanning circuit controls the application of strobe pulses to the addressing channels. The scanning circuit has switching means for switching from the application of an anode potential to the coated electrode and the application of a cathode potential to the exposed electrode to the application of the cathode potential to the coated electrode and the application of the anode potential equal to the reference potential to the exposed electrode when one of the channels is addressed.

Plasma addressed liquid crystal display devices in which liquid crystals cells serve as a display element and plasma discharge regions for driving them are adjacently arranged, a space ranging over all the scanning units is provided. Such a space has no partitions in the discharge regions. The discharge regions are formed as a continuous space over the entire screen, or every plural scanning units. On the base plate (2), discharge electrode pairs A₁,K₁...A n ,K n ) for generating discharge plasma are provided. Thus, discharge plasma generated in the vicinity of each discharge electrode pair serves as a scanning unit. The liquid crystal cell functions as a sampling capacitor, and the discharge plasma functions as a sampling capacitor. By scanning of the discharge plasma, an image display is achieved.

An apparatus for and a method of addressing data storage elements (16) employs an ionizable gas to address the storage elements for storing data in and reading data out of them. The storage elements are defined by the overlapping areas of multiple column electrodes (18) extending in a common direction on a first substrate (48) and multiple channels (20) extending in a common direction on a second substrate (54). A layer of dielectric material (46) separates the first and the second substrates, which are positioned face-to-face and spaced-apart with the direction of the channels transverse to that of the column electrodes. Each of the channels is filled with an ionizable gas and includes a reference potential electrode and a row electrode electrically isolated from each other. The column electrodes receive data drive signals, and the row electrodes and reference potential electrodes receive data strobe signals. The addressing apparatus is configured so that for each storage element the ionizable gas functions as an electrical switch that changes between a conducting or plasma state and a nonconducting or de-ionized state in response to an applied data strobe signal. The ionizable gas functions to either store data in or read data out of the storage element. If the storage element includes a layer (44) of material having electro-optic properties and receives incident image-carrying light, the ionizable gas functions to select and store image data across the layer and thereby provide a display system having gray scale luminance.
摘要:
A reflective display is formed using two orthogonal fiber arrays and an electro-optic material. The bottom fibers contain plasma channels, used to address the electro-optic material. Wire electrodes built into the fibers address both the plasma and the electro-optic material. The fibers are composed of glass, plastic or a combination of glass and plastic. Color is imparted into the display using colored fibers, adding a color coating to the surface of the fibers, or adding the color to the electro-optic material. The electro-optic material consists of a liquid crystal material, electrophoretic material, bichromal sphere material, electrochromic material, or any electro-optic material that can serve to create a reflective display. Another possible reflective display is formed using an array of hollow tubes filled with an electrophoretic material sandwiched between two plates.

The display panel has a glass backplate (1) a first surface of which is provided with barrier ribs (3) of glass frit. Electrodes (5) are present between the ribs (3). A front member (10) rests on the barrier ribs (3) and is sealed to the backplate (1). The front member (10) has electrodes (11) which extend transversely to the ribs (3). The glass frit of the ribs (3) mainly consists of ZnO, B2O3 and V2O5 and has a minor content of SiO2, PbO and/or CuO, and BaO and are mechanically strong. The glass frit combines a relatively small thermal coefficient of expansion and a relatively low sintering temperature, which makes the frit particularly suitable for use with a backplate (1) of borate glass, particularly an alkali-free borosilicate glass.
