Display units ( 1 ) comprise display panels ( 90 ) which are divided into active parts and inactive parts. The driving of an entire display panel ( 90 ) requires a minimum amount of time, which amount of time increases with an increasing number of rows and columns. By providing data signals to the pixels ( 11 ) located in active parts, and by supplying reference signals simultaneously to pixels ( 11 ) located outside the active parts, most of an amount of time available in a frame period is used for the active part, and, for a given frame period, the number of rows and columns of the display panel ( 90 ) can be increased. Respective parts are made active during respective 3 periods. A part may comprise a group of columns (ADG, BEH, CFI) and/or a group of rows (ABC, DEF, GHI). The display panel ( 90 ) may comprise multiplexing circuitry ( 50 ) and/or shift register circuitry ( 60 ) to reduce the number of connections between the display panel ( 90 ) and the rest of the display unit ( 1 ).
