ELECTROPHORETIC DISPLAY UNIT

摘要

Electrophoretic display units (1) are driven with a reduced amount of power by efficiently clocking a data signal into the data driving circuitry (30) only once and then supplying this data signal subsequently to two or more pixels (11) in two or more different lines. This can be done in case the pixels (11) in a same column require the same data pulse, like a shaking data pulse (Sh 1, Sh2) or a reset data pulse (R). As a result, time is saved, which allows frame periods to be shorter. Even more time can be saved and even shorter frame periods are possible when combining the efficient clocking with the parallel driving of groups of lines (70-72).
