INTERFACE SIGNAL

(1) Signal Definition and Function





Non-interlaced Display Mode

This is the standard mode. When a 480 line non-interlaced signal is received, a 480 line non-interlaced scanned display occurs within the unit. If a full 480 line signal is not received, it is shown in the upper portion of the screen. The lower portion is left blank.

The input signal conditions are shown below. Figure 4 shows the timing.






Interlaced Display Mode

In NTSC standard timing display mode (RGB 8-bit TTL Signal), when the PARITY Signal (toggle signal) is input, the interlaced display mode is automatically activated. By displaying the same data on the adjoining two scanning lines, 480 lines non-interlaced scanning is done. However, the display position of odd fields and even fields are offset one line on the screen.




NOTE: n:1~240

Input signal conditions are shown below. Figure 5 shows the timing.

WARNINGS

(1) Screen

1. Do not display the same pattern for an extended period of time. It is ideal that control of display should be designed so that accumulative lit time of each pixel is the same. If the same pattern is shown for an extended period of time, the brightness of that area will be decreased over areas due to the degradation of phosphor or the brightness will be increased due to the fact that the electrode surface will be activated more than other areas.

(2) Power Source Connection and Interruption

1. Do not connect or disconnect any of the DC input lines such as VCC, VS when certain voltage exists on it.

2. Even if the AC input is cut, there is still residual power. After 1 minute, disconnect the PDP input connector.

3. To connect and disconnect the PDP unit power source, follow the sequences below:
- Connect: Connect Vcc ! Connect Vs
- Disconnect: Disconnect Vs ! Disconnect Vcc

(3) Connecting and Disconnecting the Control Signal

Use the following sequences to connect and disconnect the PDP unit's power source and input control signal.

For safety's sake, if the control signal has not been input, the high voltage circuit interrupt function will start. (For instance, if Vsync is interrupted, the display will disappear.)

If the control signal is re-input, operations will begin again.

Connecting power source, control signal:
- Connect input control signal !
Connect input power source

Disconnecting power source, control signal:
- Disconnect input power source !
Disconnect input control signal

(4) Mounting an IF Card Near the Unit

Screen noise will occur if an IF card is placed near the PDP unit. Place it away from the PDP unit.

(5) Changing Brightness and Color

Depending on the type of usage, there may be a slight change in the brightness and color over time. There may be an increase of both X-value and Y-value by 0.05 in chromaticity. In this case, adjust it by using external data signal.

(6) Luminosity Outside the Display Area

There is a slight (brightness approx. 3~4cd/m2) neon luminescence shown outside the display area on the panel shown below. Mask this part so that it may not be seen on the display surface.



1. REFERENCE

1.1. DISPLAY RATE AND BRIGHTNESS SPECIAL FEATURES

This unit has an automatic power control function for VS power source.

If the Vs power source exceeds 550mA (display rate over 40%), brightness will gradually decline.

If a display rate increases over about 40%, the display brightness will be decreased gradually from the "APC non-operation level" to the "APC operation level" (max. 5 seconds).

Note: Definition of "Display Rate"
Display Rate 100% =
Every sub-pixel is lit at the maximum brightness.



1.2. ZIGZAG PATTERN AND GRAYSCALE FEATURES

This unit has an automatic power control function for address power source arranged in the unit. If the display rate of zigzag pattern increases over about 80%, grayscale level decreases from 64 (260K colors) to 32 (32K colors). If the rate is over about 90%, grayscale level is 16 (4K colors).

2. Display Quality Specifications

2.1. Display Cell Defect Specifications

This color, plasma display panel (color-PDP) has 1920 horizontal (640 x 3 [three colors: red, green, blue]) x 480 vertical color cells. These color cells are made to display color through on/off and brightness controls.

In some cases, a panel may have defective cells that cannot be controlled. These defective cells can be categorized into three types:

(1) Non-lighting cell defect: Defect in which the cell is always off

(2) Non-extinguishing cell defect: Defect in which the cell is always on

(3) High intensity cell defect: Defect in which the cell lights excessively brighter than other cells of the same color

The display cell defect specifications define the allowed limits for display cell defects and are used as the criteria in determining whether a panel is shipped.




NOTES:

*1 Cells may flicker in the boundary areas of lit and unlit patterns of a display; however, the flickering is not abnormal.

This phenomenon is rare and occurs only with certain combinations of display pattern and gradient brightness level. Because this phenomenon cannot be eliminated with the lighting control method used, it will not be considered a display cell defect.

2.2. Brightness Variation Specifications

The color-PDP uses ultraviolet light produced by gas discharge to illuminate fluorescent units and displays color using color-coated fluorescent units. Uneven coating among the fluorescent units and inconsistent discharge characteristics cause slight differences in brightness among the sections in a panel. These differences in brightness among the panel sections produce brightness variations, which can be categorized into two types:

(1) Full-screen brightness variation: Slight differences in brightness that occur over the entire screen

(2) Localized brightness variation: Sharp differences in brightness that occur in adjacent sections of the screen

The brightness variation specifications define the allowed limits for these brightness differences and are used as the criteria in determining whether a panel is shipped.




*2 Some scan lines may appear brighter than other scan lines. However, this is not abnormal. Brightness variations in lines, bands, or stripes are governed by the localized brightness variation specification.

2.3. Color Specification

The color-PDP produces a white display by mixing the light produced by red, green, and blue fluorescent units. Consequently, the variation in light emitted from the individual fluorescent units in a panel produces slight differences in degree of whiteness.

The color specification defines the allowed limits for the degree of whiteness and is used as the criterion in determining whether a panel is shipped.




3. Expected Service Life

The service life characteristics of the color-PDP have two facets: the brightness life, which is determined by the fluorescent unit characteristics, and the display defect life, which is determined by the discharge characteristics.

For each facet, the expected service life is expected to be about 10,000 hours (this is not the guaranteed service life).

4. Repair and Maintenance

4.1. Repair and Maintenance Support

The color-PDP unit is a subassembly display module in which the display panel and the drive circuit are integrated into a single unit.

Because of product configuration and contents considerations, Fujitsu is unable to provide any field repair or maintenance services. Consequently, the product prices do not include any service costs.

Repair and maintenance for the color-PDP unit is limited to products that are returned to the Fujitsu factory. Service costs, if any, are determined based on the fault condition. If a service cost is involved, the service will be implemented only after customer approval is received.

4.2. Spare Units

As described in item 4-1, repair and maintenance services are performed only at the factory and require about one month after the product is received at our factory.

Because we are unable to provide immediate service in the field, Fujitsu recommends customers to purchase enough spare PDP units according to the urgency of their operations.

5. Guidelines on Using the Color-PDP

The color-PDP unit is a display device module that consists of a glass panel section and a drive circuit section. The glass panel section is a glass substrate on which electrodes, fluorescent units, and other components are realized through thin-film and thick-film processes. The drive circuit section is a printed circuit board onto which the electric circuits that drive the glass panel section have been incorporated. When designing and handling the color-PDP unit, be sure to follow the guidelines described below.

5.1. General Notes

Considerations and packaging for delivery and transport

When delivering or transporting the unit, take special precautions so that excess vibration or shock is not applied to the unit. If the unit is dropped or if excess vibration or shock is applied, the glass panel section may break and the drive circuit section may become damaged. The unit should be delivered or transported in Fujitsu's shipment packaging or similar packaging.

Static electricity precautions during handling, delivery, and transport

The drive circuit section uses C-MOS integrated circuits that must be protected from static electricity. Therefore when delivering or transporting the unit, be sure to place the unit in an antistatic bag.

When handling a color-PDP unit, take adequate grounding precautions to prevent static electricity buildup.

Instructions on cleaning the glass panel display section

To clean the glass panel display section, apply water or a neutral detergent to a piece of soft cloth (gauze) and wring the cloth tightly before wiping the display. Make sure that no water contacts the terminal connectors on the side of the glass panel display section. Never use chemical solvents, such as paint thinner or benzene, to clean the display section.

Instruction on storing and restarting the color-PDP unit

When storing the color-PDP unit, select an environmentally controlled location. Avoid any environment in which the temperature or humidity becomes too high. If you are storing the unit for a long period of time (over one month), place the unit together with a dehumidifying agent, such as silica gel, in a moisture-proof bag and keep the unit in an environmentally controlled location.

When a unit that has been in storage for a long time is restarted, an operation lag, which is characteristic of PDPs that use electric discharge, may occur. If a lag occurs, operate the unit again without the filter in brightly lit environment. Maintain this condition until the unit operates normally. Once the unit begins to operate normally, the same lag-free operation that took place before the unit was stored will return.

Handling during operation and drive voltage

The color-PDP unit has a section that operates using high voltage (about 340 volts). If you need to handle an operating unit, take the proper precautions against electric shock and never touch the drive circuit section.

The capacitors in the drive circuit section remain temporarily charged even after the unit power is turned off. After turning off the power, be sure to wait at least a minute before touching the unit.

Connecting and disconnecting signal and power connectors during operation

The color-PDP unit is equipped with various protection circuits that automatically stop unit operation if an interface signal or the power voltage becomes abnormal during operation.

Although the protection circuits will operate if a connector is connected or disconnected during operation, the protection circuits were not designed for this purpose. Therefore never connect or disconnect a signal or power connector while the unit is operating.

The capacitors in the drive circuit section remain temporarily charged even after the unit power is turned off. After turning off the power, be sure to wait at least a minute before touching the unit.

Unit modification and warranty

The glass panel display and drive circuit section of the color-PDP unit are closely connected and function as a pair. If the unit is arbitrarily recombined, restructured, or disassembled, Fujitsu will not be responsible for the function, quality, or any other item of the modified unit. Do not recombine, restructure, or disassemble the color-PDP unit.

5.2. Guidelines on Device Design

Fixed display and screen burn-in

Because the color-PDP uses fluorescent units to emit light, the fluorescent units, like a CRT, deteriorate in proportion to display frequency, and brightness decreases.

Thus, if the same pattern is displayed continuously (fixed display), that fluorescent units in that section deteriorates faster (brightness decrease) compared with the other display sections and screen burn-in occurs.

This phenomenon can be reduced effectively by periodically inserting a uniform, full-screen pattern or installing a screen saver-type display software.

When the display pattern is changed, the areas that had been illuminated may appear temporarily (few minutes) brighter. This phenomenon is characteristic of color PDPs and is due to activation of the discharge surface. It does not indicate an abnormal display.

Unit ambient temperature and unit ventilation

In the color-PDP unit, both the glass panel display section and the drive circuit section radiate heat.

The device design should include thorough heat-dissipation measures, like installing the unit in a well-ventilated area. In addition, the unit ambient temperature should be maintained so that it does not exceed 455C. The temperature of the glass panel display section becomes especially high because of the installed filter and the additional heat that radiates from drive circuit. The device should be designed with ventilation fans and other heat-dissipation measures.

Furthermore, the ventilation should be designed to prevent condensation and adhesion of conductive particles because part of the unit operates at a high voltage (340 volts).

Glass panel cracks and device structure

The devices should be designed so that metal and other hard objects do not contact the glass panel display section and forces due to heat or mechanical distortion are not applied.

Be careful not to break the glass when assembling the device or handling the color-PDP unit. Also, when handling the unit, wear gloves or other hand protection to prevent injuries that can occur if the glass breaks.

Interface signals and external noise

The color-PDP unit displays patterns using display data and synchronizing signals that determine the horizontal/vertical operation timings.

If noise interferes with these signals, it can cause the display to become unstable and, in some case cases, lead to a failure. The unit has protection circuits that operate to prevent noise-induced failures and may stop the display.

Do not place equipment that can act enormous noise sources near the unit interface cables, and keep the cables as short as possible.
