Evaluation of Parameters of the Mathematical Model of Color Response Performances of LCD-panel
Abstract
Purpose: To describe and study the colorimetric features of LCD panels, we introduce a mathematical model of color rendition specified parametrically. The parameters of the model depend upon the technological features of LCD-panel manufacturers, being unique for every maker. The purpose of our research is developing a technique to evaluate the parameters of this model. Methods: The estimates of the model parameters were calculated on the basis of theoretical analysis and processing of the optical measurement results. The theoretical analysis was applied to the chromaticity coordinates of the color coverage triangle vertices and to the coordinates of the white color point suggested by the manufacturer in the technical documentation. The color coordinates or chromaticity coordinates for any given set of colors displayed on the LCD screen in the test mode were obtained during experimental illuminance measurements. Results: Mathematical expressions were suggested to evaluate the parameters of the color rendition model, obtained in three different ways based on the solution of a system of equations connecting the parameters: models and chromaticity coordinates for white, blue, red and green points; model and color coordinates for three random colors measured by a colorimeter; models and chromaticity coordinates for four random colors measured by a colorimeter. Practical relevance: The results obtained during the research and development work are used by the designers of modern indication equipment and manufacturers of LCD-panels for colorimetric calculations and for the estimation of technological tolerance of chromaticity coordinates among the display units in mass production.Published
