This part of IEC 62679 series 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 this part of IEC 62679 series 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.
