Abstract
The claimed invention is directed to a flat panel display having R, G, and B unit pixels. At least one of the R, G, and B unit pixels includes at least two or more transistors, each having source and drain regions. At least one drain region in the source/drain regions of at least one transistor in the transistors has a resistance value different from a resistance value of at least a drain region of the other transistor. The difference in resistance values may be accomplished by doping each drain region with a different concentration of dopant or by shaping each drain region differently.
