Plasma display

Abstract

The display includes a back plate, a front plate setup above the back plate parallelly, multiple electrode couples and data electrodes. Each electrode couple including first clear electrode and second clear electrode setup below the front plate parallelly. Each data electrode setup on up side of the front plate and perpendicular to each electrode couples. The crossing points between data electrodes and electrode couples defines multiple display units. According to three colors, the multiple display units are divided into first, second and third display units. An electrode couple of second and third display unit includes at least a groove.

Description

field of invention [0001] The invention relates to a plasma display, in particular to a plasma display which uses the area of ​​a transparent electrode to control the color temperature. Background technique [0002] Plasma displays have been gradually applied to large-size and large-area display devices. The principle of light emission is to generate ultraviolet light by driving plasma (plasma) through electrodes to irradiate the fluorescent body, so that the fluorescent body emits visible light. [0003] see figure 1 . figure 1 It is a schematic diagram of a conventional plasma display 10 . The conventional plasma display 10 includes a casing (not shown), and a rear panel 12 is installed on the rear panel 12 in parallel with a front panel 14 . The lower side of the front plate 12 is provided with a plurality of electrode pairs (electrode pair) 16, each electrode pair 16 includes a common electrode (common electrode) 17 and a scan electrode (scan electrode) 18, a dielectr...

AI Technical Summary

Problems solved by technology

[0008] However, since the spacing of the barrier ribs 44 of the plasma display 40 is not uniform, part of the barrier ribs 44 must be made smaller than the spacing of the barrier ribs 24 of the plasma display 10 at the same resolution, which means that the manufacturing accuracy must be increased to produce a smaller pitch barrier wall 44

Generally speaking, the distance between the barrier walls covering the blue phosphor 30B must be more than 20% larger than that of the green 30G and red 30R, in order to have the effect of significantly improving the color temperature. Now that the resolution requirements are getting higher and higher, this This solution will increase the difficulty of manufacturing

In addition, since the plasma display 40 greatly reduces the discharge space of the second display unit 32R to reduce the red brightness of the second display unit 32R, the overall luminous efficiency of the plasma display 40 will be reduced.

On the other hand, since the distance between the barrier walls 44 of the plasma display 40 is different, the discharge spaces of the first display unit 32B, the second display unit 32R, and the third display unit 32G are different, so the operating voltage range of each display unit ( operational voltagemargin) inconsistencies
