Don't care! LED display anti-static is very important!

Static electricity has always been a concern for electronic products. The same is true of the Led industry, LED display color problems, brightness issues, technical issues are all concerned, and the treatment of display static electricity is easily overlooked. 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 main source of static electricity that affects the circuit is the human body, plastic products, and related equipment and equipment. Static power from the use environment has the following items:

1. Object, material

2. Floor, work tables and chairs

3 work clothes, packaging containers

4. Painted or waxed surfaces, organic and fiberglass materials.

5. Cement floors, painted or waxed floors, plastic tiles or floor leather.

6. Chemical fiber work clothes, non-conductive work shoes, and clean cotton work clothes.

7. Plastics, boxes, boxes, bags, trays, foam liners.

2. Electrostatic discharge failure

Sudden failure and potential failure: In the use of the environment, the static failure of more than 90 is a potential failure, the performance of the circuit's resistance to over-stress and weakened, and the service life is shortened.

3. Anti-static measures

1. Equip static-sensitive circuit personnel with knowledge of electrostatics and related technologies.

2. Establish an ESD work area. Use anti-static flooring, anti-static worktables, anti-static grounding leads, and anti-static devices in the area. Control the relative humidity to 40 or more.

3. The harm caused by static electricity to 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. ESD-damaged devices 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. Security and Control Procedures for ESD: Most ESD and EMD companies have very similar ESDs and have successfully implemented the ESD control, manipulation, and main program of the device. 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 Led display is currently the most widely used for large screen applications. Since the cost is also a relatively high product, electrostatic knowledge training is required. The relative humidity is controlled at 40 or more to minimize the damage of the LED display during transportation.
