Colour characterization of handheld game console displays

摘要

During recent years, research on colour vision has used traditional visual colorimeters, cathode ray tubes (CRT), and personal-computer controlled LCD-TFT screens to generate chromatic stimuli. We here explore the possibilities offered by a particular family of electronic devices whose use has lately been expanding rapidly, and which have one or more TFT screens and all the hardware needed for portable and autonomous use: handheld game consoles. We considered the different consoles available on the market, and as a result conducted an initial comparative study of two models - Sony PSP and Nintendo DS. As a result of this study, we checked the potential of using the Nintendo DS console, of which more than 100 million units have been sold worldwide. The results of our tests clearly indicated that it can be used as a tool in colour vision and physiological optics at the same technical level as CRT or TFT screens.
