A display driver which drives at least a plurality of scan lines of a display panel having a plurality of data lines and a plurality of pixels in addition to the scan lines. The reflective and transmissive regions are arranged in strip shapes lying across pixel rows. The analysis tools may include meta-data definitions for different sources of the snapshot information. Further, since the ionic liquid can be simply provided on a substrate to be in contact with the carbon nanotube and a gate electrode, the configuration that chemically modifies a surface of the carbon nanotube with a plurality of polymers as in the conventional gas sensors is not needed, and the configuration can be simplified correspondingly. The spring element is mounted in the driving body in a non-rotatable manner with respect to the axis of the tool shank and in a radially deflectable manner against its spring force. The reactive dye mixtures of the present invention are suitable for exhaust dyeing, printing, continuous dyeing or discharge printing of a blended or interwoven fabric of cellulose fibres or cellulose nylon blends.
