Approximation Approach To The Theory-based Flat Panel Image Display Technology

The purpose of this dissertation is to study the problems of driving algorithm of high quality image display in panel display devices, and adjustment of color based on the virtual gamut transformation with merging approximation theory as essential means.This dissertation includes six chapters. In chapter one, the general research aspects of technics applied in panel image display, the quality of image display, and to which the appraisement methods of display panel bear a reference are described. The study project and content are confirmed.In chapter two, the basic knowledge related to panel display drive technology and chromaticity is introduced. Some terminology of functions approximation theory is presented.In chapter three, the counter drive method of panel display device is studied. A drive method of unequalized clock counter in panel display which uses no dissimilarity @ subclass to achieve precision unequalized clock counter correction based on functions approximation theory is proposed. The new method is acquired based on the particular analysis results of the display drive design projects which adopted counter drive method in which the balance between the display image quality and the cost of drive circuit is given. Finally, synthesis comparison examples are given.In chapter four, the time sectional scan method panel display device is studied. Since time sectional scan method (TSSM) acts as the dominant partner in the panel display, attention is drawn to the aspect in the drive methods. According to functions approximation theory, the method of complex merging approximation TSSM which utilize multiple dissimilarity @ subclasses to achieve precision visual perception scale control is proposed. The comparison examples are given thereinto. The next purpose relates to the weigh time sectional scan method which is a branch of TSSM, and a complex weigh distribution scale control method is given by analysis of preliminary factors of traditional means in display panel.In chapter five, the research work focus on color gamut transform correction in panel display. A method of color gamut transform correction which introduces the concept of virtual gamut space is presented to solve the problem of luminance and chromic disuniformity which arises from the differentia of chromic and drive characteristics of each module or pix on the same display panel. And the high quality of image displayed on the panel is ensured.In chapter six, a brief summary of the dissertation and a plan for future research are given.
