What is PD IEC/TR 62679-5-1 - Legibility of EPD in spatial frequency about?
PD IEC/TR 62679-5-1 is the fifth part of the multi-series that discusses electronic paper displays.
PD IEC/TR 62679-5-1 is a technical report, that specifies the legibility in terms of contrast, spatial frequency, and reflection of the screen as a function of the physical parameters of an EPD. This legibility evaluation model is introduced through both subjective and objective assessments.
The scope of PD IEC/TR 62679-5-1 is restricted to EPDs using segment, passive, and active matrixes with monochromatic type displays.
Who is PD IEC/TR 62679-5-1 - Legibility of EPD in spatial frequency for?
PD IEC/TR 62679-5-1 electronic paper display is useful for:
- Manufacturers of electronic display devices
- Electrical engineering
- E-books and E-magazines
- Engineers and scientists engaged in EPD development
- Policymakers
- Business leaders
- EPD company
Why should you use PD IEC/TR 62679-5-1 - Legibility of EPD in spatial frequency?
An electronic paper display or electronic ink display is a technology that is designed to mimic the appearance of ordinary ink on paper.
PD IEC/TR 62679-5-1 offers permanent formulae to decide on the legibility level of EPD compared with paper, which can lead to the specification of EPD with regard to the human action of reading.
Legibility is one of the human actions of reading, which falls in the category of subjective assessments; on the other hand, the properties of EPDs fall in that of physical specifications, that is, objective assessments. The legibility in PD IEC/TR 62679-5-1 is described by using a five-level the rating system is revealed to show as a function of physical parameters.
In PD IEC/TR 62679-5-1, legibility is suggested as having two essential parameters, that is, the spatial frequency, which can represent the complexity or size of a letter, font, or symbol, and the contrast, which shows the brightness between a character and its background.
This technical outcome, which can assist company leaders and policymakers in developing suitable market strategies and reactions, may attract new clients, compel them to rethink their existing bases or motivate them to establish new strategies in the field of EPD business.
