The National Institute of Standards (NIST) has published color brightness standards and detailed explanation papers. The organization cooperates with industry to develop and apply new technologies and standardize them, and uses the new standards for projector production. Whether at work, home or school, people want to experience colorful video and projection content. These contents have evolved from black and white images to impactful color images. Color can portray a more in-depth and moving story, enhancing the communication between people. With the development of projection technology, there are significant differences between various projectors. Some projectors focus on improving the brightness of white light. For today's colorful multimedia content, viewers certainly want the projector to optimize brightness and color at the same time. Previously, the industry did not have a simple method to objectively evaluate the color performance of the projector. The National Institute of Standards (NIST) mentioned in the explanation of the color brightness standard that color brightness (CLO, Color Light Output) is a new indicator that can evaluate the color performance of the projector. In order to get the best picture, the white light brightness of the projector should be equal to the color brightness. At the same time, he also gave a method of measuring color brightness: because a good look and feel depends on the brightness and color saturation, it is necessary to measure both: white light brightness and color brightness. In the measurement of color brightness, red, green, and blue are measured on 9 square points, which is similar to the measurement of white light brightness. When the brightness of color is equal to that of white light, the picture is vivid and credible. When the color brightness is less than the white light brightness, the picture will be dim. When viewing the value, the brightness of white light should be equal to the brightness of color. When the two values ​​are not equal, the picture looks unbalanced in color. White may be bright, while the colored parts appear dim, flat, and unreal. Beginning in April 2011, Epson, a leading manufacturer of 3LCD technology, launched a new website on the "color brightness guide" for the global market. The purpose is to help people who are choosing and preparing to purchase projectors to learn this important new standard for projection.
