  • Samsung's newly developed high luminance efficiency 42" VGA plasma display panel is introduced. A new discharge cell structure, SDR (Segmented electrode in Delta color arrayed Rectangular subpixel) has been applied to a full size panel for the first time. In this paper, we describe how this new discharge cell structure for high efficiency is integrated to an energy saving plasma display with better picture quality.

  • Resonance radiation trapping has a great influence on the characteristics of vacuum ultraviolet(VUV) photon emissions in AC PDP cell. We calculate the spatial andspectral distributions of VUV photons, which are radiated by excited Xe in AC PDP cell by Monte Carlo method. Especially a dip in the spectrum at center frequency is discovered both in simulation and in experiment. We give a physical explanation of this phenomenon by the concept of frequency-dependent mean free path of VUV photons.

  • This paper presents the experimental results on the 3-electrode DC-PDP which has a common electrode to improve the PDP life cycle. The measured DC characteristic proves the effectiveness of common electrode absorbing about half of discharge currents. The waveforms for pulse memory operation of3-electrode PDP without crosstalk could also be determined from the I-V characteristics. The pulse memory drives of 8*8 cell array show the frequency response fo memory margin and the luminance efficiency of 3-electrode PDP are quite different from genrally known characteristics of 2-electrode DC-PDP.

  • The newly designed Ac-PDP(plasma display panel with comb-type electrode) structure was fabricated by using the screen printing method and the electrical and optical characteristics were measured under the various discharge conditions. The minimum firing voltages measured under pure Ne and Ne+Xe mixture gas with the application of 10 kHz square wave were 190V and 160V, respectively. The firing voltages of the PDP cell with the comb-type electrode were compared with those of the cell with matrix electrode under the same discharge condition. The firing voltage of the PDP cell with comb-type electrode was 15 V lower than that of the PDP cell with conventional matrix electrodes.

  • In this experiment, we have investigated that the transported space charge between sub-pixels in AC-plasma cell discharge. The test pulse 30 V, $5{\mu}s$ was applied to the address electrodes of neighbor cells of discharge occurred cells. And we have measured the transported space charge between sub-pixels in accordance with the various last sustain pulse widths t(time gap between the rising edges of sustain and test pulses) of 0.2 to $3{\mu}s$. It was observed that the peak value of transported space charge has been shown to be 21.5pC at $1.0{\mu}s$. And the IR peak value have been occured after $0.51{\mu}s$ with respect to sustain voltage.

  • There is asymmetric in horizontal and vertical side of PDP cell. Every vertical line has BM(Black Mask) to improve luminance contrast. When error diffusion is processed in PDP system, these problems make an error bigger. In 4 inch PDP system, every red, green, blue color of test pattern is presented and each luminance is measured. That is called horizontal(H), diagonal right(R), diagonal left(L) and vertical(V). In red channel, high luminance descending order is V-H-R-L. In green channel, V-H-L-R. In blue channel, V-M-R=L. After average luminance of each direction is calculated. new weighted error diffusion(Weighted ED) is proposed. In digital image signal processing, the error in weighted ED is differ from ED's. The image of weighted ED is more less error compare to conventional ED and close to original image. As the gray level linearity and big size panel is adopted, weighted ED could produce good image.

  • In the current PDP technology, one of the most important issues in AC PDP is improvement of luminance and luminous efficacy. To improve luminance and luminous efficacy, new cell structure of PDP containing long discharge path is necessary. However, it causes an increment of firing voltage. In order to decrease firing voltage of AC PDP having long discharge gap, the protrusion electrode is proposed. To drop the firing voltage, the protrusion electrode is inserted into the forward area of the main discharge gap. This paper presents measurements of detailed optical and electrical characteristics of AC PDP with protrusion electrodes. The experimental results show that the proposed structure with gap 80um has lower firing voltage to 27V than that of the conventional long gap structure. Moreover, the ICCD(Intensified Charge Coupled Device) images of the proposed structure show quick discharge generation by 0.07usec and longer continuation by 0.05usec than that of the conventional long gap structure. Therefore, the proposed protrusion electrodes have higher luminance by 12.5% than that of the conventional structure, as having no decrement of Luminous efficacy.

  • Several ITO-less PDP cell structures are presented to improve luminous efficacy. The ITO-less PDP have been applied recently at actual panel manufacture. The influence of ITO-less PDP cell structure on the discharge characteristics has been investigated by using three-dimensional fluid simulation. The variations of electrode geometry parameters such as gap distance, cross bar length, and hump length are investigated for the optimization of cell design.

  • AC PDP with surface micro discharge has a structure that all discharge electrodes are arranged on the front glass panel, and the rear glass panel merely serves as a cover glass to form the micro discharge space. The relationships between the dischage voltage and the structure among such as electrode width, distance between electrodes, discharge space gap, and dielectric layer width are investigated.

  • We have investigated the luminous efficiency of various cell resolution and structure from 50" FHD to 50" QFHD Plasma Display. The suggested test panels have two different cell array types which are the delta and matrix cell array type. The results showed that, in the case of the suggested QFHDs, the firing and sustain voltage were increased and voltage margin was decreased. These results are caused by the reduced wall voltage and increased charged particle loss, at the side wall. The luminance of the suggested QFHDs was lower from 20% to 40% than that of the suggested FHDs and the power consumption was higher from 42% to 83% than that of the suggested FHDs. In conclusion, the maximum luminous efficiency of the suggested QFHD(D110) has reached about 38%, compared with suggested FHDs($\fallingdotseq$ 2.7 lm/W).
