IEC 62679-3-2:2013 is restricted to electronic paper display modules using either segment, passive, or active matrix, and either monochromatic, or colour type displays. In order to achieve a useful and uniform description of the performance of these devices, specifications for commonly accepted relevant parameters are put forward. The purpose of IEC 62679-3-2 is to indicate and list the procedure-dependent parameters and to prescribe the specific methods and conditions that are to be used for their uniform numerical determination.
