COB small pitch is a higher definition screen, which uses high-density and high-brightness LED modules, with bright colors, high brightness, fine display effect and other advantages. However, with the growth of use time, the COB small-pitch LED module may experience some failures or need to be maintained. In order to ensure its normal operation and extend its service life, the following are some tips for COB small-pitch LED module maintenance.

First of all, regular cleaning is an important part of maintaining COB small-pitch LED modules. Because the COB module is exposed to the air for a long time, dust and dirt will accumulate on the surface of the screen, so it is necessary to regularly use a soft brush or hair dryer to clean the dust. Before performing maintenance of the COB small-pitch LED module, make sure that the power supply is disconnected and that it is operated by a professional. Proper tools and equipment need to be used during maintenance to prevent damage to the module. Wear ESD gloves and clothes to avoid the adverse effects of static electricity on the module.

For the cleaning of the COB small-pitch LED module, a clean, soft fine fiber cloth should be used to gently wipe. Do not use cleaners containing alcohol, solvents or strong acid bases to avoid damaging the protective layer on the module surface. Especially when cleaning glass panels, avoid using sharp objects or harsh cleaners to avoid scratching or damaging the surface.

Secondly, pay attention to the inspection and maintenance of power supplies and cables. The COB small-pitch LED module needs a stable power supply when working, so it is necessary to regularly check whether the power and signal lines of the COB small-pitch LED module are normal. If the power cable or signal cable is broken, short-circuited, or in poor contact, repair or replace it in time. In addition, the heat dissipation of the module should be checked to ensure the normal operation of the heat dissipation system to avoid overheating resulting in damage to the module.

In addition, regular detection and correction of the display effect of the COB small-pitch LED module is also an important part of maintenance. Through professional equipment and software, the detection and correction of LED module color uniformity, brightness consistency and other parameters can ensure the accuracy and stability of the display effect.

To sum up, the maintenance skills of the COB small-pitch LED module include regular cleaning, waterproof and moisture-proof, power supply and cable inspection, display effect detection and correction. Only by strengthening the maintenance of the COB small-pitch LED module can we ensure its normal operation, extend its service life, and bring better viewing effects.
