In some projects, it is with rational application of project management, in order to promote the project completed on time and with high quality. LED display more complex engineering, project management is essential. Project management is the use of specialized knowledge, skills, tools and methodologies in project activities, the project to achieve or exceed stakeholder needs and expectations. Which means that the stakeholders involved in the project and everyone affected by the project activity. Project Time Management includes the timely completion of the process so that the project must be implemented. The main process includes activity definition, sorting activities, activity resource estimating, activity duration estimates, develop schedules and schedule control. Events definition involves identifying specific project team members and stakeholders to complete the project deliverables man must be completed; the program involves estimating Events resource estimate completed; activity sequencing involves determining the dependencies between project activities and the formation of the corresponding file the type and number of required resources; activity duration estimating the number of units involved in the estimated hours to complete specific activities needed; to develop a schedule involves analyzing the sequence of activities, activity duration and resource requirements, and schedule constraints, and thus to develop a project schedule ; schedule control involves the control and management of the project schedule changes. Light-emitting diode (LED) since its inception. Has achieved full color and high brightness, and on the basis of the blue and violet LED LED on the development of white LED. It has brought the history of mankind lighting? Leap. Compared to offer LED bar lights and fluorescent and incandescent, LED bar with its small size LED, all solid, long-life, environmentally friendly LED bar design, saving a series of advantages, has been widely used in automotive lighting, decorative lighting, mobile phone flash medium and large sizes for bar LED, namely NB and LCD.TV sources such as the display module. 2l century has become one of the most promising high-tech field is a LED electroluminescent device implanted by Ⅲ ~ Ⅳ compounds, such as gallium phosphide (GaP), gallium arsenide phosphide (GaAsP) semiconductor made In ~ I-DN electric field. electrostrictive effect radiative recombination of electrons and holes occurring part of the energy will be converted into light energy. That quantum effects, without radiative recombination lattice oscillations generated the remaining energy into heat . LED bar supplies, bar LED, LED bar Shenyang, Shenzhen poem by Benjamin Chu Science and Technology Development Co., Ltd. Guangzhou Branch offers.
