37、 achieve a useful and uniform description of the performance of liquid crystal display (LCD) devices, specifications for commonly accepted relevant parameters are put forward. These fall into the following categories: a) general type specification (e.g. pixel resolution, diagonal, pixel layout); b)

38、optical specification (e.g. contrast ratio, response time, viewing-direction, crosstalk, etc.); c) electrical specification (e.g. power consumption, electromagnetic compatibility); d) mechanical specification (e.g. module geometry, weight); e) specification of passed environmental endurance test; f)

39、 specification of reliability and hazard / safety. In most of the cases a) to f), the specification is self-explanatory. For some specification points however, notably in the area of optical and electrical performance, the specified value may depend on the measuring method. The purpose of this stand

40、ard 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 m

41、easurements as the purpose of this standard is not to give a detailed account of good practice in electrical and optical experimental physics. Furthermore, it shall be assured that all equipment is suitably calibrated as is known to people skilled in the art and records of the calibration data and t

42、raceability are kept. BS EN 61747-30-1:2012 8 61747-30-1 IEC:2012 LIQUID CRYSTAL DISPLAY DEVICES Part 30-1: Measuring methods for liquid crystal display modules Transmissive type 1 Scope This part of IEC 61747 is restricted to transmissive liquid crystal display-modules using either segment, passive

43、 or active matrix and achromatic or colour type LCDs. Furthermore, the transmissive modes of transflective LCD modules with backlights ON are comprised in this document. An LCD module in combination with a touch-panel or a front-light-unit is excluded from the scope because measurements are frequent

44、ly inaccurate. Touch-panels or front-light-units are removed before measurement. Throughout the main body of this standard, an integrated backlight is assumed to provide the illumination for the measurements. Deviations from this (e.g. segmented displays without integrated backlights) may usually be

45、 handled in the same way as display modules with integrated backlight, if an external backlight is provided. However, in the case where one of the two situations should be handled differently, this will be specifically stated. 2 Normative references The following documents, in whole or in part, are

46、normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

49、given in IEC 60050-845:1987 apply. NOTE Several points of view with respect to the preferred terminology on “monochrome“, “achromatic“, “chromatic“, “colour“, “full-colour“, etc. can be encountered in the field amongst spectroscopists, physicists, colour-perception scientists, physical engineers and electrical engineers. In general, all LCDs demonstrate some sort of chromaticity (e.g. as a function of viewing angle, ambient temperature or externally addressable means). Pending d
