CHAPTER 6 CONCLUSION AND FUTURE WORK
6.2 F UTURE W ORKS
6.2.3 Database for Optimization of RCS Index
The application of the RCS index, at current stage, is restricted in certain conditions because of the limited database till now. In view of psychometric scaling [74], current RCS index is regarded as an ordinal scale which is useful to rate the sequence of samples. However, when the conditions change, the results may be different correspondingly. More psychophysical data are required from various FSC LCDs (wide luminance range, different multi-primary driving schemes, different panel size, etc.) under different viewing conditions (from dark, through dim, to bright environment, etc.). With the additional parameters of the viewing conditions, modifications on some color appearance models, such as CIECAM02 [21], may be necessary to calculate RCS value.
