Driver circuitry of each pixel provides pixel drive currents to respective LED display elements of the pixels of a display. An output transistor arrangement for each column drive circuit within a pixel has a plurality of output transistors (70, 72, 74) in parallel, and one or more of these are selected in order to provide desired output characteristics. Thus, the output of each column drive circuit can be tuned to provide desired output characteristics. In order to select an output transistor, fusible links of non selected transistors may be broken, or further transistors may connect selected transistors to a gate control line while non-selected transistors are connected to a de- select line. ® KIPO & WIPO 2007
