The relationship between brightness and viewing angle

The relationship between brightness and viewing angle

In different environment condition,the request brightness of LED display are different according to the environment contrast ratio.Indoor LED display request a lower brightness but high request for viewing angle. Outdoor LED screen's brightness is higher than environmental brightness, and also with better grey degree, therefore its viewing angle request is not as high as indoor one, generally between 35-- 50 degree. If the viewing angle of LED lighting part become lower, the brightness will be higher. Vice versa. If the contrast ratio between LED screen's brightness and environmental brightness is higher, the led display's showing performance will be more colorful. However, if the brightness of LED display is too much higher, it is bad for people's eyes; and much more power are being wasted , much more heat being produced ,then tempreture become much higher, and then led chip's brightness decrease much faster, of course, its lifespan will become shorter. Hereby, LED display's brightness and viewing angle should be fixed by the request of application environment.
