Display Technology is the most effective means of communicating information. Displays are used in a number of industries for information presentation. Manufacturers of display devices are responsible for the safe performance of their product. Display measurement is an important consideration as it ensures the readability and safety of the display device. According to the report “Display Measurement and Evaluation” by Christine Hall of the National Physical Laboratory, several factors should be considered during the measurement process. These factors, referred to as display characterization, include spectral information, environmental information, temporal information, and spatial information. They work with the characteristics of the eye to bring about the display measurement.

Importance of Display Measurement and Evaluation

Display measurement ensures the readability and safety of display devices. This is extremely important as display devices are not limited to computer monitors and television screens but are also used in such safety-critical devices as surgical diagnostics, ...
... car speedometers, and air traffic controls. Measurement allowsfor the following:

Compliance of display device with health and safety requirements
Experimentation and compatibility with eye reception
Quality control usage by display manufacturer
Evaluation and comparisons between manufacturers

Standard measurement defines display timings, resolutions, and electrical and mechanical interfaces. Measurement evaluation considers the following:

Screen uniformity
Brightness and color
Contrasts
Power efficiency and usage
Physical weight and dimensions

Instruments Used for Measuring Display Devices

There are several instruments designed for display measurement. Some are used for general device measurement while others are used for specific devices. Instruments for measuring display devices include the following:

Photometric measuring instruments— these includecolorimeters and light meters, such as a luminance meter. Colorimeters measure color absorption while light meters measure light intensity.
Radiometric measuring instruments — these include scanning devices and spectroradiometers. Spectroradiometers measure the wavelengths of individual colors of light.
Conoscopes— colorimeters or light meters used in an angular presentation.
Goniometer — measure angles or allows rotation to an angular postion.

Digital technology plays a vital role in information communication. Industries involved in this technology have important decisions concerning the manufacturing of their product. Display measurement, for one, must be taken into consideration as it contributes to the safety of the product. Display measurement instruments can be obtained through manufacturers specializing in optical test and measurement solutions.
