DEFINITION

Classification: 349/48

Plural nonredundant transistors per pixel:

(under subclass 42) Subject matter wherein each pixel includes two or more transistors for purposes other than redundancy.

(1) Note. Included here are a pair of N and P transistors for each pixel or a pair of transistors connected to different address lines for each pixel.

(2) Note. Excluded from this subclass is the use of transistors for redundancy purposes. For such excluded subject matter, see SEARCH THIS CLASS, SUBCLASS below.
