As an important production base of global LED display, China has many manufacturers, but the prices of various manufacturers are far apart. The deciding factor in determining the price of display screens is the selection of materials for each home. Display screens, as bulk consumer goods, are of critical quality and longevity. Cheap and poor quality products will only bring endless maintenance difficulties to customers; it will cause more and more serious after-sales services for manufacturers.
The factors that determine the display price
The use of LED die materials is different: good LED die has high brightness, low brightness attenuation, long service life, good color consistency, and a slightly higher price. The use of connectors: high-quality connector plug-in high frequency, is conducive to long-term maintenance of the display operation; price is higher than the inferior connector. The control system uses: The high-quality control system makes the display screen have the higher refresh frequency, the color gray scale and the contrast, the software operation is convenient.
Display installation and after-sales service
A. In the production process, our display screens have taken care to simplify the structure and facilitate the installation. At the same time, we also provide the customer with a frame structure diagram as a reference. Our quotations do not include installation costs unless otherwise agreed in the purchase contract.
B. The warranty period for the display is 3 years. During the warranty period, all non-operating damaged parts can be replaced free of charge, but the customer needs to send the replaced damaged parts to the company at their own postage costs; within two working days after our company receives the new parts Mail to customers.
LED FAQ
LED pays great attention to anti-static measures. The following are some explanations for static electricity and anti-static electricity:
1. The source of static electricity
The source of static electricity that affects the circuit is mainly the human body, plastic products and related equipment and equipment. Among them, the static power source from the use environment has the following items: objects, materials, floors, work tables and chairs, work clothes, packaging containers, and paints or waxes. Surfaces, organic and fiberglass materials; concrete floors, painted or waxed floors, plastic floor tiles or floor leathers; chemical fiber work clothes, non-conductive work shoes, cleaning cotton overalls; plastics, boxes, boxes, bags, trays, foam Plastic liner.
2. Electrostatic discharge failure mode:
Sudden failure and potential failure.
The static failure of more than 90 in the use environment is a potential failure, which manifests itself in the weakening of the circuit's resistance to electrical overstress and shortened service life.
3. Anti-static measures:
1) Training on the use of electrostatic sensitive circuit personnel for electrostatic knowledge and related technologies.
2) Establish an anti-static working area in which static-discharged floors, anti-static worktables, anti-static grounding leads and anti-static devices are to be used, and the relative humidity should be controlled to 40 or more.
3) The harm caused by static electricity to the electronic equipment may be released anywhere from the manufacturer to the field equipment. The hazard is caused by insufficient, effective training and equipment manipulation failure. LEDs are devices that are sensitive to static electricity. INGAN chips are generally considered "first place" susceptible to interference. And ALINGAPLEDSSHI "second place" or better.
4) Devices with damaged ESD can show dimming, blurring, extinguishing, short or low VF or VR. Devices that are damaged by ESD should not be confused with electronic overloads, such as: faulty current design or driving, chip mounting, wire shield grounding or encapsulation, or common ambient induced pressure.
5) ESD security and control procedures: Most ESD and EMD companies have very similar ESDs and have successfully implemented ESD control, manipulation, and main programs for all devices. These programs are instruments that have been used to detect quality effects since ESD. The ISO-9000 certification also lists him as a normal control program.
4. Transportation and packaging
In daily operation, ESD-sensitive devices should always be stored in anti-static bags or containers. This includes detailed inventory, transportation and WIP. Prevention during transportation includes consumed fleets, boxes or other equipment, such as conductive wheels or draglines, which are grounded when transporting ESD equipment. The standard for clarifying and guaranteeing the quality of packaging materials is ANSI/ESDS11.31-1994, the standard for normal use of packaging marks is ANSI/ESD/ESDS8.1-1993, and the standard for packaging materials is ANSI/EIA-541. -88 and ANSI/EIA-588-91.
