The assessment of the performance of an display i.e. TV set strongly depends on human visual perception which directs. The research and development of the display. The visual perception is influenced by one's different culture background. Study on the difference helpful to understand how to improve the characters of display sets. In this paper

a special experiment is performed

in which

a set of still pictures is displayed on a pair of colour TV sets

and the are asked to assess the image colorfulness for different white point setting and different contrast. Analysis of the evaluation results

indicatis that most people like the more colour saturated picture. Then from the results

the preferred white point setting and contrast can be got. The evaluators are divided into two parts: expert and non-expert. The results shows that the mean value from experts is smaller than that from non-experts.Comparisons of the results with similar experiment done by Philips research. An analytical result is obtained for visual perception study on people of different cultural background between the east and the west countries.
