What is a Display optical measuring instrument?

A display optical measuring instrument is a measuring instrument that incorporates a mechanism for measuring optical elements such as light intensity, spectral characteristics, transmission and reflection characteristics into a display measuring instrument. Display measuring instruments also measure optical elements, but display optical measuring instruments are more specialized in their measurement. General optical measurement methods are evaluated based on various JIS standards. For example, there are JIS B 7071 as a method for measuring the refractive index of optical glass and JIS B 7072 as a method for measuring the temperature coefficient of the refractive index of optical glass. By incorporating these optical measurement methods into a display optical measuring instrument, it becomes possible to understand more detailed display characteristics than display measuring instruments.

Application of Display optical measuring instrument

Conventional displays have various problems such as large thickness and weight, and the image quality of the display is wavy. However, in recent years, displays have become smaller and thinner. In addition, display image reflection technology is also evolving. For example, the displays that are often used these days include organic EL displays and liquid crystal displays. The organic EL display expresses the hue by emitting light from the element itself such as a diode as a light emitting method. On the other hand, the liquid crystal display is equipped with a backlight under the liquid crystal and expresses the hue by passing through the color filter placed on the liquid crystal. In this way, a wide variety of combinations of light emission methods for displays have been developed, and there is no limit to the utility value of digital camera displays, train operation screens, aircraft and warships, etc., and image reflection technology is also glass or liquid crystal. It depends on such things. Therefore, it can be said that display optical measuring instruments are used in various industries, coupled with the development of display technology.
