Herma ITEL S15 LCD screen exhibits amazing brightness effects in a wide range of ambient light, making it bright enough to read in a dark enviroment, even outdoors in the sunlight.
Contrast is defined as the ratio of the maximum brightness value (full white) divided by the minimum brightness value (full black). Generally speaking, the larger the contrast value, the better the screen. The contrast of the screen can reflect whether the it can express rich color gradation and picture level. The higher the contrast, the higher the sharpness of the image, the clearer the image, the more vivid the color displayed on the screen, and the richer the layering.
Each arrow represents the color difference between a target color pattern (base of the arrow) and its actual measurement (tip of the arrow). The longer the arrow, the more visible the color difference is. If the arrow stays within the circle, the color difference will be visible only to trained eyes.
