In the selection of industrial LCD screens, we often have to pay attention to a variety of parameters, in which the brightness of the screen is the most concerned by many customers. In general, the brightness of industrial LCD screens ranges from 250nits to more than 1000 nits, so how should the brightness of LCD screens be tested? 

1. Hardware test method. The luminance colorimeter adopts the method of trichromatic filter, which can measure brightness, color temperature cielab, cieluv, color difference, etc., and the four measuring angles can be switched. It is suitable for the measurement of low brightness in the field of low brightness which requires a small measuring angle (0.1 °/ 0.2 °). If the long distance measurement is carried out, the extension line can be used to measure the main engine and the inductor separately. The instrument additional keyboard (optional) can be used for a variety of functions, including input color coefficient and brightness deviation. In addition, it can also be used in computer for data storage, analysis and printing, and has a wide range of applications in lighting engineering, film and television, architecture and other fields. 

2. Software testing method. Monitors Matter Check Screen is a professional LCD brightness test software, it can not only detect industrial LCD screens, but also test CRT (cathode ray tube) display. It includes many test items, which can detect the color of LCD, response time, text display effect, "bad points" and other vital indicators.
