3293 results about "Plasma display" patented technology

A plasma display panel (PDP) is a type of flat panel display that uses small cells containing plasma; ionized gas that responds to electric fields. Until about 2007, plasma displays were commonly used in larger televisions (30 inches (76 cm) and larger). Since then, they have lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays. Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016.

The invention relates to a high-strength aluminate silicate glass and a chemical toughening method thereof, and belongs to the silicate glass field. The glass comprises the following chemical components (weight percent): 55 to 65 weight percent of SiO2, 0.1 to 3 weight percent of B2O3, 6 to 24 weight percent of Al2O3, 3 to 9 weight percent of MgO plus CaO plus BaO plus SrO, 0 to 1 weight percent of ZrO2, 0 to 2 weight percent of ZnO, 0.1 to 0.5 weight percent of Cl2, 0.1 to 1.0 weight percent of Sb2O3, 0.1 to 0.5 weight percent of SO3 and 0.1 to 0.5 weight percent of F2, and belongs to a aluminate silicate glass system. The high-strength aluminate silicate glass is prepared through a known plate glass production method, and then is subjected to the strengthening treatment by adopting the chemical toughening method. The glass has high permeability of visible light, and relatively common soda lime glass, neutral medicine glass and alkali-free high-aluminum glass have good shock resistance property, high scratch resistance property and high durability. The high-strength aluminate silicate glass is applied to the screen surface protection of plasma display products and liquid crystal display products, the protection of touch screens, the screen protection of automated teller machines, and the screen protection of other electronic products (Mobile phones, PDAs and media machines, etc.), thereby effectively preventing the impact and the scratch damage to the glass surface of display products. The high-strength aluminate silicate glass contains no harmful elements.

Drive control system for a fiber-based plasma display

A full color fiber plasma display device includes two glass plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top fiber array includes identical top fibers, each top fiber including two sustain electrodes located near a surface of the top fiber on a side facing away from the viewer. A thin dielectric layer separates the sustain electrodes from the plasma channel formed by a bottom fiber array. The bottom fiber array includes three alternating bottom fibers, each bottom fiber including a pair of barrier ribs that define the plasma channel, an address electrode located near a surface of the plasma channel, and a phosphor layer coating on the surface of the plasma channel, wherein a luminescent color of the phosphor coating in each of the three alternating bottom fibers represents a subpixel color of the plasma display. Each subpixel is formed by a crossing of one top fiber and one corresponding bottom fiber. The plasma display is hermetically sealed with a glass frit. The sustain and address electrodes are brought out through the glass frit for direct connection to a drive control system.
