Abstract
This paper describes a measurement system to characterize the performance of Plasma Displays. The system records the light behavior per grayscale and phosphor. With a simulation mode land signal analysis, the system predicts the level of several artifacts, like: dynamic false contour, motion-blur, large area flicker, and fade-in/fade-out flicker.

1.Introduction
To characterize the performance of Plasma Display Panels (PDPs), the time and luminance related properties, such as Dynamic False Contour (DFC), motion blur, large area flicker, and fade-in/fadeout flicker are significant factors [1]. These factors are perceived by human eyes, but are difficult to predict and record. Extensive subjective perception experiments are required to evaluate the performance of each display in each factor and for each condition. These experiments are time consuming and require a group of experts that can score these factors consistently. In this way it is also difficult to benchmark several Plasma Displays (quantitative comparison) and investigate the essential mechanisms behind these disturbing factors. Some objective measurement systems, such as the moving camera system, are available and described in literature [2]. However, these systems are usually special for only one feature and also costly.
In section 2 a measurement system is introduced that is easy to build and operate, and able to characterize most of the time- and luminance related performance factors. It works by measuring the light behavior for each input code and each primary color (phosphor). Based on the measurement results, the software simulates human perception to predict the motion artifacts. This is described in section 3. With the frequency spectrum analysis, the system can also predict the seriousness of different kinds of flicker. The results are presented in section 4. In section 5 some conclusions are drawn.

2. Measurement System
The measurement system aims at measuring the temporal light behavior for each input code and each phosphor.
Figure 1 represents the framework of the measurement system. The Programmable Video Pattern Generator (PVPG) generates display pattern, selected by the computer through I2C interface. The PVPG can also convert the DVI signal from computer told, used as interface to the PDP. The PDP receives its settings through I2C and pattern signals through the LVDS interface. Luminance meter records the luminance and chromaticity values of the display, after which the data is transferred to the computer through the RS232 interface. A fast V (􀁏)-corrected photo-diode (for instance Hamamatsu S9219-01), is used to record the luminance signal. Before the Tectonics TDS754D oscilloscope acquires the photo-diode signal, first the signal is amplified and care is taken that the noise is sufficiently suppressed. The data is transferred to the computer through a GPIB interface. This computer works as the main control of the whole system. It selects the display patterns, records all the measurement data and completes the data analysis. With the luminance values recorded as calibration data, the relation between voltage signal from photodiode and light signal from screen is established. In this case the time varying voltage signal v (t) from the photodiode can be carefully converted into the measured luminance signal L (t), according to (1).
