<br> Projection products including multimedia projector, video / digital exhibition stand, central control system, screen and other professional products and computer, AV class General products, widely used in digital, training, Conference control, medical consultation, the courts, as well .as multimedia to demonstrate performance etc. As the industry in recent years 3-4 are developed, market volume is small, but quickly developing trends. Therefore, the projection industry is a relatively high degree of specialization. This also predestined projection products that do not .have the same characteristics of many other industries, such as a high technology content, in a professional application as the main collective decision to purchase, professional knowledge is universal, maintenance cycle length, etc. <br> <br> Before purchasing <br> .<br> In the decision to purchase projector (instrument) product, you must consider "the need and possibility." "Actual needs" refers to as close as possible to their practical needs, rather than to buy, buy, or not to save .money and buy. Most users don't really know their own needs, often wastage and trouble. Users typically need to consider the following six (5W and 1H). <br> <br> WHAT you need to do? <br> < .br> WHERE: somewhere? <br> <br> WHEN: when to use? <br> <br> WHO: anyone who uses, management, who is responsible for purchasing? <br> <br> What grades WHICH: select? .<br> <br> HOWMANY: purchase amount? <br> <br> "Possibilities" refers to the possibility of realization of the main funds, policy advice, as well as technology and market is mature, three factors. <br> < .br> 1. procurement funds: how much flour, this is a standard, otherwise they will be asking for trouble. <br> <br> 2. policy advice: professional products in general use specific procurement processes and collective decision making procurement model, .you need to fully test the units of collective decision-making, conducive to the adoption of reasonable programmes. <br> <br> 3. technology and market status: some users need to go far beyond existing projector technology and the ability of a projector .market will be a lot of trouble. If users submit five-year warranty, a large number of procurement, 3-5 day delivery as well as video showcase displays A4 paper 5 characters, and so on cannot achieve the requirements. Based on a " .need to be "fully considered and proposed procurement plans and performance requirements, you will need to tender invites tenders for specialized staff. <br> <br> Procurement <br> <br> To determine the user really needs, then enter the projector procurement .procedures. It should be in charge of the organizational user and expert, Attn thematic visits, select the best cost performance, focus on the following aspects. <br> <br> 1 products, projection of performance indicators and function <br> <br .> A) narrow performance indicators include brightness, resolution, bulb type, service life, trapezoid correction, picture in picture, local amplification, resolution, zoom ratio, etc., should be selected according to the actual situation. In consideration of performance indicators to .expenditure clearly the main performance indicators and effective performance refers to the stall, the former is to grasp such as projector is the key indicators; display resolution and a brightness of main performance index is the sharpness, zoom ratio, ease of use and functionality of expand .. While the latter is used for the user does not have the significance of performance to lower costs. If users plan to projector lift, there is no need to aim higher as the trapezoid, because reasonable installation there is no question of a trapezoid, but .will reduce the clarity of the projector; if projector only computer signal, Nan to picture in picture; if the projector is mainly used in conjunction with the exhibition stand, the projector's local amplification is meaningless; if ordinary classroom use exhibition stand there is no need .to have the image capture function, and so on. <br> <br> B) generalized performance indicators also includes vendor qualification and after-sales service.

In the score, the effective performance indicator is the evaluation of key performance indicators in General is a defect or highlight of their advantages. (Scoring criteria see tables) <br> <br> Scoring criteria table <br> <br> .Evaluation of the merits to score <br> <br> Highlight system advantages fatal defects not scoring <br> <br> Important important advantages to defects + / -5 <br> <br> General General advantages of soft defect + / -2 .<br> <br> 2. bidding company qualification <br> <br> A business license validity: Enterprise). <br> <br> B) distributors of valid authorization: determine if a factory authorized dealers, and to manufacturers of professional .after-sales service effectively. <br> <br> C) manufacturers specifically authorized on this subject: the amount of purchase to support large user, manufacturers usually take special preferential treatment or special after-sales service measures shouldTo strive for. <br> .<br> D) has five or more professional and technical personnel: in General, with five professional staff can provide technical stability relative comprehensive, professional service.

Such .as brightness, color, image uniformity, stability and so video projector to brightness and color effects. Observation of the angle, the image and the text you want to test, and the projector's indicators of settings for the initial value. <br> B) .function shicong, shicong special features. <br> <br> 5. on the subject <br> <br> A) qualification, polling company and product compliance audit should take a marked deprecated system as long as there is a qualification does not provide .or that is false, immediately cancel the bid of the company or product. <br> <br> B) price factors can account for 50%. <br> <br> C) major technical indicators and effective technical indicators leading to 20% .. <br> <br> D) strength, success stories, service level and service commitments accounted for 30% should be considered for warranty, training, regular maintenance, company size, professional strength, success stories.
