--- Part 3-2.Test methods for photoelectric properties.

This document is equivalent to IEC 62679-3-1:2014 "Electronic paper display devices Part 3-1.Optical performance test methods".

Introduction

In order to meet the production, manufacturing, inspection and export trade needs of electronic paper display devices in my country, better promote exchanges in related fields in cooperation with the technical cooperation, it is necessary to formulate a series of standards for electronic paper display devices. GB/T 43789 "Electronic paper display devices" is proposed to consist of the following parts constitute.

--- Part 1-1.Terminology. The purpose is to define the basic terminology of electronic paper display devices.

--- Part 1-2.General specification. The purpose is to determine the general specification for the inspection of electronic paper display devices.

--- Part 2: Basic ratings and characteristics. The purpose is to determine the optical performance, electro-optical characteristics and environmental characteristics of electronic paper display devices.

Ratings and characteristics for environmental testing.

--- Part 3-1.Optical performance test methods. The purpose is to determine the standard test conditions and Test Methods.

--- Part 3-2.Photoelectric performance test methods. The purpose is to determine the standard test conditions and Test Methods.

--- Part 3-3.Optical test methods for display devices with integrated lighting units. The purpose is to determine the optical properties of display devices with integrated lighting units.

Optical testing method for sub-paper display devices.

--- Part 4-2.Environmental test methods. The purpose is to determine the environmental test methods for electronic paper display devices.

--- Part 5-1.Readability of electronic paper displays under spatial frequency. The purpose is to determine the readability of electronic paper under spatial frequency.

Assessment standards.

Electronic paper display devices Part 3-1.

Optical performance test methods

1 Scope

This document describes standard test conditions and test methods for the optical performance of electronic paper displays (EPDs).

This document applies to reflective monochrome or color passive field or active matrix electronic paper display device applications.

For electronic paper display devices with integrated light source units (ILU), the integrated light source unit needs to be turned off during testing.

This document does not apply to products with color systems exceeding three colors.
