When it comes to the display viewing angle, there is a phenomenon worthy of our consideration: LED display, especially outdoor display, the viewing angle is basically people from the bottom up, and to the existing LED display products morphological point of view led TV Half of flux vanishing into the sky. Uniformity and clarity LED display technology development today, the uniformity has become the most important measure of the merits of the display. It is often said LED display "little brilliant, brilliant piece" is a serious image problem for uneven between pixels and modules metaphor. Professional thing to say is "dust effect" and "mosaic." The maximum brightness under certain environmental illumination led manufacturers, LED display of each color in the highest gray level, brightness maximum brightness when. In a nutshell is the use of software to set the brightness of the display using a light gun in the normal direction when measured as 255 white. For the outdoor LED display according to the environment used to maximum brightness have different requirements, because in the case of relatively strong ambient light led what is meant, it is required LED display brightness is higher, in order to let people see on the screen what is displayed. Under normal circumstances, the display look northward for maximum brightness requirements low, long reach 4000CD / m2 will be able to meet the requirements, and ride south of display brightness of the entire screen is required to achieve 7000CD / m2, east and west and south of the requirements are the same, because most of the time will have a direct exposure to sunlight will the LED display. Theoretically require more than 5500CD square meter brightness brightness is sufficient. led light word, led, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin.
