US Patent:

39959430, Dec 7, 1976

Filed:

Oct 6, 1975

Appl. No.:

5/619734

Inventors:

Raymond Joseph Jasinski - Dallas TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02F 136

US Classification:

350160R

Abstract:

A totally solid electrochromic display cell comprising a display electrode of tungsten oxide or vanadium oxide, a counter electrode of metallic silver or a silver-containing compound, and a solid electrolyte of a mixed inorganic silver salt including silver iodide in contact with both electrodes.

Appl. No.:

5/507913

Inventors:

Raymond J. Jasinski - Dallas TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02F 128

US Classification:

350160R

Abstract:

Disclosed is an improved electrochromic optical display cell having a memory, long life, good contrast independent of viewing angle, reversibility, low switching voltage, and a low mean power consumption wherein a soluble colorless dye is selectively and reversibly reduced at a display electrode to form an insoluble, insulating film that markedly absorbs visible light. The electrochromic display cell includes a display electrode and a non-polarizable counter electrode which simultaneously maintains a threshold potential while providing charge transfer to a electrolytically reduce the dye during a write cycle or oxidize the dye during an erase cycle. The preferred counter electrode forms a lead/lead phosphate half cell which has a substantially stable electrochemical potential over the area of operation, reversibly undergoes oxidation-reduction and will not substantially irreversibly reduce the dye. Further, the lead counter electrode can be electrochemically restored by reverse electrolysis.

Appl. No.:

5/507896

Inventors:

Raymond J. Jasinski - Dallas TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02F 128

US Classification:

350160R

Abstract:

Disclosed is an improved electrochromic optical display cell having a memory, long life, good contrast independent of viewing angle, reversibility, low switching voltage, and a low mean power consumption wherein a soluble colorless dye is selectively and reversibly reduced at a display electrode to form an insoluble, insulating film that markedly absorbs visible light. The electrochromic display cell includes an electrode through which a potential is applied across the cell to regenerate the coulombic capacity of the counter electrode. The counter electrode is regenerated by reverse electrolysis without deleteriously affecting cell operation. In a preferred embodiment, the regeneration electrode is palladium. In another embodiment, the display electrode normally present in the display cell is utilized as the regeneration electrode. The potential applied across the cell for regeneration is larger than the normal potential applied to erase the cell.

Appl. No.:

5/573666

Inventors:

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G01N 2746

US Classification:

204 1T

Abstract:

The disclosure relates to electro-chemical sensors for sensing gaseous nitrogen dioxide in the presence of carbon monoxide, oxygen, nitrogen, sulfur dioxide, nitric oxide and in chemically compatible mixtures of these gases as well as capable of sensing gaseous materials which are more strongly oxidizing than NO. sub. 2, the sensor being formed from an Fe-1173 glass. The disclosure also relates to an electro-chemical sensor formed from 15% manganese As. sub. 2 S. sub. 3 glass which is capable of sensing gaseous materials which are more oxiding than NO. sub. 2 in the presence of NO. sub. 2, CO, O. sub. 2, N. sub. 2, SO. sub. 2, NO and in chemically compatible mixtures of these gases. The disclosure also includes apparatus for determining when NO. sub. 2 is being sensed rather than more strongly oxidizing gaseous materials by the simultaneous use of the Fe-1173 glass electro-chemical sensor and the sensor formed from 15% Mn-As. sub. 2 S. sub. 3 glass.

International Classification:

G02S 523

US Classification:

350160R

Abstract:

An electrochromic display cell having a transparent front panel with an internal conductive coating providing a pleasing external appearance, and masking a counter-electrode affixed thereto; said internal coating having a window area to permit external viewing of display electrodes affixed to the back panel, which is sealed to the front panel with a ring spacer to provide an electrolyte chamber about five to ten mils thick; external electrode contacts to the electrical leads to the display electrodes are arranged on the back or front panel.
