84 cm (33 type), 640 × 480 Pixels, Digital Module

Digital RGB signal 64 gradations each

DESCRIPTION

TheNP3302MF01 is a 33-inch color plasma display module with a resolution of 640 (H) × 480 (V) pixels and 64 levels of gray scales per each RGB color. Furthermore, in order to improve the presentation of the deepest shades of black, black stripes are laid over the ribs which separate the cells. The display offers vibrant colors we reproduced in a thin and low profile package. This device uses AC plasma technology developed by NEC and includes a 6-bit digital interface.

STRUCTURE AND PRINCIPLE OPERATION OF PLASMA DISPLAY

In a Plasma Display Panel, Row and Column electrodes are placed between 2 glass substrates. A rare gas is then filled between these substrates. When a high voltage is applied to these electrodes, the gas is activated resulting in the radiation of ultraviolet light, similar to the operation in fluorescent lamps. These ultraviolet rays then activate phosphor that has been coated on the inside of the glass substrate, and visible light is emitted from

the panel.

ELECTRICAL INTERFACE OF PLASMA DISPLAY

NP3302MF01 requires 6-bit of digital video signals for each RGB color. In addition to the video signals, 10 kinds of digital control signals and 3 different DC voltages are required to operate the display. 4 digital signals and 2 DC power outputs are provided by the display for use by external circuits.

In addition, a "PLE" (Peak Luminance Enhancement) function is provided so that images can be displayed with the ideal contrast.

Notes 1. The RGB video signal should be compensated with inverse γ circuit before inputted to the color plasma

display module.

2. When BLKH input is H level, all RGB data is read as L level (black color data).

3. When ALARM output turns to H level, High voltage power input (Sustain power supply: Vs, and Data

power supply: Vd) should be switched off immediately. When glass panel is broken, High voltage may appear at the electrode in glass cracked section and become a cause of electric shock. Failure of internal power-source causes over -power status and gives damage to the display panel and driver-circuits.

4. This alarm signal is output via the power supply connector. It has the same function as ALARM except the polarity.

* Reference value

Notes 1. Input video signal format is determined by Video Mode Signal (refer to Table 4).

2. "1H" shows 1 cycle period of HSYNC (Horizontal synchronous signal).

"1V" shows 1 cycle period of VSYNC (Vertical synchronous signal).

3. Period between "leading-edge of the synchronous pulses" and "start timing of video data valid period"

4. Period between "leading-edge of the synchronous pulses" and "start timing of RGB data valid period"

5. 230 or 240 can be selected (factory set: 240). When 230 is selected, upper 5 lines and lower 5 lines are masked

with black pattern.

6. If synchronous signal delay values are set to above numbers, display position is set to the center of the display area. Display position can be moved to up, down, right, and left by adjusting the numbers of the delay values.
