Properties of excited xenon atoms in a plasma display panel

Maximizing optical production of metastable xenon

“…These results suggest that the hybrid technique of Figure 1(d) can provide a robust method for producing relatively large long-term metastable state densities. It is important to note, however, that the long-term densities achieved here (∼10 11 cm −3 ) are still lower than those obtained using short pulsed electrical discharge techniques (∼10 13 cm −3 ) [5][6][7]. Nonetheless, the techniques described here impact applications requiring high densities for longer continuous time scales [16], and studying the transient dynamics of this hybrid approach in the pulsed regime may also be of fundamental interest.…”

“…Metastable noble gas atoms are used in diverse areas ranging from fundamental physics experiments [1][2][3][4], to applications in plasma display panels [5][6][7], ultralow-power nonlinear optical devices [8][9][10], and rare gas lasers [11][12][13][14][15][16]. In many of these applications, the production of high densities of metastable states is desirable, and techniques for efficiently promoting a substantial fraction of the ground state population to the metastable state are of paramount importance.…”

“…In many of these applications, the production of high densities of metastable states is desirable, and techniques for efficiently promoting a substantial fraction of the ground state population to the metastable state are of paramount importance. Although relatively high metastable state densities (∼10 13 cm −3 ) can be achieved for short time scales using pulsed electrical discharge techniques [5][6][7], the realization of comparable long-term steady-state densities remains a significant challenge. Standard approaches include steady state RF excitation (see, for example, [17][18][19]), optical pumping techniques [20][21][22], and a recently proposed hybrid method which combines both [23,24].…”

A novel line detection method using magnetic sensor for the optical inspection of electrical short defects on TFT LCD

“…Recently, various types of display technology have developed such as LCD (Liquid Crystal Display), PDP (Plasma Display Panel) and OLED (Organic Light Emitting Display) [1][2][3][4][5][6]. Among them, LCD is mainly composed of TFT (Thin Film Transistor), liquid crystal and backlight unit.…”
