PDP Monitor burning characteristics

Regarding the subject titled, we hereby furnish you with the following report:

1. Burning

The fluorescent substance used in the plasma module loses its brightness with the lapse of lighting time.

This deterioration in brightness appears to be a difference in brightness in relation to the surroundings, and comes to be recognized as burning.

In other words, the burning is defined as follows: when the same pattern (of the fixed display) is displayed for a long time, a difference in brightness is caused around the lighting area and non-lighting area due to deterioration in the fluorescent substance. When the present pattern is changed over to another one, the boundary comes to be seen between the lighting area and non-lighting area due to difference in brightness in the pattern shown shortly before changeover. If this condition is accumulated, the boundary or burning comes to be seen with the naked eyes.

2. Secular change in brightness

The life of brightness, defined as the reduction to half the initial level, is more than10 thousand hours on average. Conditions: All white (100% white) input at an ambient temperature of 25°C.

However, this life time is not a guarantee value for life and brightness. It should be recognized simply as the data for reference.

3.Warranty period

Burning and faults in brightness and picture elements are excluded from the warranty objects.

4.Cause of deterioration in brightness

A major possible cause of deterioration in brightness is damage in the fluorescent substance due to impact caused by ions generated at the time of plasma discharges.

5. Practical value for burning

The deterioration in brightness tends to be accelerated up to 100 hours in the initial period. In the initial period, the fixed display of patterns particularly tends to cause burning. The practical value for burning is difficult to define in concrete numerals. As described below, you are advised to take proper measures to make the occurrence of burning as slow as possible.

6. Proposed measures taken to relieve burning

So long as there is the reduction of brightness in the fluorescent substance, it is impossible to avoid the occurrence of burning. Therefore, to relieve burning, we offer you a method of entering an image input that may ensure reluctance to the generation of the difference in brightness reduction among the displayed dots.

The images from TV broadcasting involve a high rate of motion picture displays.

Therefore, there is less chance of being a cause of difference in brightness reduction among the cells. Even when the fixed patterns are displayed, they generally last for a few minutes. Since the same pattern is less liable to be displayed, there is almost no influence toward burning.

If the fixed patterns tend to be displayed for a long time, however, there occurs a substantial imbalance between the lighting and non-lighting areas, thus causing a difference in brightness as a result. In this paper, we offer you some proposals of installation, paying attentions to the two points: the reduction of difference in brightness achieved by integrated lighting time leveling and the method of edge smearing to make burning hard to be discerned.

The result from these proposals can, however, greatly depend on the contents of images and the operating environment. Therefore, we consider that it is essential to take the suitable measures in consideration of the customer’s operating environment.

Example of Proposal 1: The display position is moved while the fixed display pattern is changed over, or it is scrolled during the display.

Example of Proposal 2: If possible, a pattern of

complementary color is incorporated (for integrated time leveling).

Example of Proposal 3: The fixed pattern and the motion picture display are reciprocally exchanged, in order to minimize the display period of the fixed pattern.

Example of Proposal 4: During operation, the brightness of screen is suppressed as low as possible. For the display patterns, characters are indicated not on the black ground (non-picture area) but on the colored ground (mixture of R, G, B recommended).

7.Proposed countermeasures for the plasma module Since the PDP is a display that uses a fluorescent substance like the CRT, it is a fundamental phenomenon that burning occurs. Unlike the CRT, the PDP gives rise to deterioration in the fluorescent substance due to impact caused by ions generated during plasma display.

As a result of the above-mentioned improvements, it is possible to extend the PDP lifetime and relieve the effect of burning, but is impossible to realize the complete elimination of burning so far as a fixed pattern is displayed for a long time.
