• Electronic paper display - Part 3-2: Measuring methods - Electro-optical

  Description:

  The scope of this document is restricted to electronic paper display modules using either segment, passive, or active matrix, and either monochromatic, or colour type displays. If electronic paper display module with combination of an external touch-key-panel or an external front-light-unit, remove those for measuring. If it is not possible to remove, it should be mentioned . However, it is not necessary to mention about protective sheet. This document shall be read together with other specifications to which it refers. It gives details of the quality assessment procedures, the inspection requirements, screening sequences, sampling requirements, and test and measurement procedures required for the assessment of electronic paper display modules. 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 paper 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. It is assumed that all measurements are performed by personnel skilled in the general art of radiometric and electrical measurements as the purpose of this paper is not to give a detailed account of good practice in electrical and optical experimental physics. Furthermore, it must be assured that all equipment is suitably calibrated as is known to people skilled in the art and records of the calibration data and traceability are kept.
