NEC Display Solutions Ltd. has a concept “to display the actual thing as it is” for developing monitors. Based on this concept, we develop various kinds of technology for materializing the optimum color management. Calibration, Uniformity, and Luminance are specific keywords for this concept. As a result of this development, the users in the photograph industry and the printing industry who are professionals in images use our products. Furthermore, our monitors for medical diagnostic imaging are also used by the medical industry.
This means the operation of equipment, such as monitors and printers, for expressing the subject color precisely. Thus, the unit verifies the current color reproduction conditions and compensates the settings for reproducing the colors to be expressed more exactly. For instance, the color calibration is an operation for compensating color expressions that have been changed due to changes on standing from ones that were expected to be expressed originally by the monitor.
There are two types of calibrations: the hardware calibration method where the display will calibrate colors automatically to the values set by the user previously, and the software calibration method that uses software from other manufacturers to calibrate colors manually.
This means an operation for standardizing color tones on different monitors. For instance, this function is used to reproduce different color expressions on different monitors of a photographer and a designer with the same color tone for the reasons as mentioned above. Specifically, the basic color information is transmitted to both monitors by using the color information and profiles, and then the colors are compensated accordingly.
This means preparation of an environment where all persons involved in the operation process share common colors. To standardize precise color expression, the respective monitors must have a function to execute precise calibration.
The color calibration adjusts the white point temperature, brightness, and gamma value. This function shall basically set these three items to the values desired by the user and save on the monitor.
For the High-grade series, all models are equipped with the hardware calibration function. The dedicated application software and the corresponding color sensor are required to execute the actual color calibration.
Among the high-grade series products, LCD3090WQXi is equipped with the self-calibration and the copy calibration functions.
