MR LED
(1) DVI display card interface is in line with the computer display interface of the international standards;
(2) without opening the chassis, to facilitate the installation;
(3) memory, dynamic screen display capabilities;
(4) hardware and software compatibility;
(5) to support all operating systems and application software, display flexibility and convenience;
(6) mass production, low cost, easy to maintain.
(1) light-emitting part: module full color display module is generally green and yellow, pure green module expensive; SMD full color generally use pure green core;
(2) display: Module full color pixel visual feeling of thick, low brightness, easy mosaic phenomenon; SMD full color consistency is better, higher brightness;
(3) Maintenance: module difficult to maintain full-color, high replacement costs of the entire module; SMD full color and easy to maintain, repair and replacement of a single lamp;
(1) to display content;
(2) visual distance, the perspective of the confirmation;
(3) Screen resolution requirements;
(4) installation of environmental requirements;
(5) cost control;
(1) procurement of raw materials: the LED lamp procurement cycle is longer, especially imported die, order cycle takes 4-6 weeks;
(2) The production process is complex: subject to the PCB design, production casing, plastic irrigation, adjusting white balance;
(3) strict structural requirements: the general cabinet design, the need to consider the wind, rain, lightning.
