Appeal 2006-3013 Application 10/367,849 line is wider than a data line lines to save more power without decrease a display area since the power supply lines(VDD) consume more power than the data lines since the power supply lines(VDD) needs to drive transistors(TR) and LEDs and the data lines(column lines) only drive transistors(T) (see Dingwall's figure 2 and Kawaguchi's column 15, lines 24-32) and this decision is generally recognized as being within in the level of ordinary skill in the art. On the other hand, there is no one or no rule to restrict that the power- feed line can not wider than a scanning line in an LED or EL display device; and Dingwall can choose any one of the above three choices. (Answer 7). Further in the statement of the rejection the Examiner finds that modifying Dingwall would be obvious since: it is well known in the art that the resistance of a power supply line can be reduced by increasing the width of the power line according to the teaching of Kawaguchi et al and a formal of R=YI/A, wherein A is the cross sectional area; I is the length of the wire and Y is the resistively of the material; the width of power supply lines are wider than the data lines would be save more power without decrease a display area since the power supply lines(VDD) consume more power than the scanning lines since the power supply lines(VDD) needs to drive transistors(TR) and LEDs and the data lines(column lines) only drive transistors(T) (see Dingwall's figure 2 and Kawaguchi's column 15, lines 24-32). (Answer 4) Thus, the issues before us are whether: a) the combination of Dingwall and Kawaguchi teaches or suggests a display where the power line portions on the display are wider than the data line portions as claimed; b) the combination of Dingwall and Kawaguchi teaches or suggests the advantages realized by the device; 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Next
