What is PD IEC/TR 62977-2-3 - Test pattern of electronic display devices about?  
PD IEC/TR 62977-2-3 is the second part of electronic displays in multi-series that discusses electronic display devices for the measurements of optical properties. 
PD IEC/TR 62977-2-3 is a Technical Report, that reviews the impact of test pattern colour content and image loading on the measured display's photometric and colourimetric performance. Experimental data for several display technologies are presented to demonstrate the need for using a broader range of colours in the test patterns and measuring the display at an image loading level appropriate for the intended application.
Who is PD IEC/TR 62977-2-3 - Test pattern of electronic display devices for? 
PD IEC/TR 62977-2-3 on electronic display devices is useful for: 
- Manufacturers of electronic displays devices
- Suppliers/retailers of electronic display devices
- Electrical engineers
- Theatres owners and operators
Why should you use PD IEC/TR 62977-2-3 - Test pattern of electronic display devices?  
Optical measurement is a method of monitoring critical dimensions of manufactured parts in many industries. This optical measurement refers to noncontact measurement using various light sources.
Current display measurement standards mainly use simple test patterns to estimate the display performance. These test patterns would typically contain only one colour or a colour with a black background. However, as recent research has shown, modern display electronics can be content-aware, and adjust the display rendering based on the input image content. Therefore, multi-colour test patterns that more closely simulate realistic image content are recommended in order to better represent the display performance.
PD IEC/TR 62977-2-3 discusses the impact of the display drive electronics and image processing on the display rendering behaviour, and reviews research results that demonstrate the need for multi-colour test patterns and average picture level loading considerations.
PD IEC/TR 62977-2-3 describes three average picture levels on display patterns and apply various optical measurement methods to them. Some of these measurements like common box optical measurement methods are meant to be used during the research and development and quality control period of products. Implementing these methods given in PD IEC/TR 62977-2-3 helps you to create a good quality electronic display with clear picture perception, better resolution and sharp image quality.
The measurement methods in PD IEC/TR 62977-2-3 not only helps you identify the specifications of electronic display devices but also improve them.
