Application of hollow channel between sustain electrodes to improve discharge characteristics in alternating current plasma display panels

Abstract

A front-panel structure with a hollow channel between sustain electrodes for an alternating current plasma display panel is proposed to achieve a low breakdown voltage and short discharge time lag due to the strong electric field in the hollow channel. When compared with a conventional structure, the structure with a hollow channel produced a 15% firing voltage improvement, 8% minimum sustaining voltage improvement at a neon gas pressure of 150 Torr, and 8% discharge time lag improvement at a sustaining voltage of 270 V.

Effect of Gold Nanorods in an MgO Protective Layer of AC Plasma Display Panels

“…The IR response time is affected by the intensity of the electric field on the discharged cell. 7,20 Accordingly, we believe that the total intensity of the electric field on the discharged cell of the MgO protective layer with the silica-coated Au NRs was greater than that of the MgO protective layer without the silica-coated Au NRs because an enhanced local electric field induced by the LSPR of the silica-coated Au NRs in the near-IR region and the nanoscale rough surface of the MgO protective layer was added. This enhanced local electric field can lead to enhanced discharge characteristics compared to the conventional MgO protective layer.…”

“…The firing voltage was measured by gradually increasing the square sustain voltage pulse until the discharge was initiated. Also, the minimum sustain voltage was measured by decreasing the square sustain voltage pulse until the first cell began to turn off . According to the literature, the minimum sustain voltage is related to the wall voltage. , Therefore, the magnitude of the wall voltage of the test panel part with the silica-coated Au NRs most likely increased.…”

“…The IR emission from the test panel has a wavelength of 828 nm, and it originates from the relaxation of Xe from a higher excited state to a lower excited state. The IR response time is defined as the time difference between the 10% level of the peak voltage and the 10% level of the peak IR value . The IR value was measured with a photodetector (Hamamatsu, C6386).…”

“…Figure 5 shows the firing voltage, minimum sustain voltage, luminance, the power density, and the luminous efficacy of the test panel part with the conventional MgO protective layer and 20 According to the literature, the minimum sustain voltage is related to the wall voltage. 21,22 Therefore, the magnitude of the wall voltage of the test panel part with the silica-coated Au NRs most likely increased.…”

“…The IR response time is defined as the time difference between the 10% level of the peak voltage and the 10% level of the peak IR value. 20 The IR value was measured with a photodetector (Hamamatsu, C6386). The response time of the MgO protective layer after inserting the silica-coated Au NRs decreased compared to that of the conventional MgO protective layer.…”
