Today, we will discuss protective and maintenance measures for advertising light boxes and light guide plates.
1.Avoid touching the light guide plate with wet or sweaty hands
After removing the protective film, avoid touching the light guide plate with wet or sweaty hands.
2.Notes on handling and cutting advertising light boxes
When handling advertising light boxes with light guides, avoid rubbing or bumping the light guide surface. When placing the original light guide, avoid sand entering the light guide joints. When cutting the light guide, clean any foreign objects from the cutting machine surface. The quality of light box directional signs, light tubes, and time-controlled switches varies greatly. All are national standards. Rolling light boxes and systems are relatively unregulated within the industry. Due to competition, prices are determined by the materials chosen for rolling light boxes. Advertising light box manufacturers use electric drills, Phillips screwdrivers, screws, steel saws, wood saws, chisels, pliers, small nails, latex, utility knives, steel wire saws, and acrylic glue. When selecting square tubes for advertising light box production, material costs can be chosen based on the customer’s required light box quality. This can be done by most general processing factories. Remember to ensure proper waterproofing and ventilation/heat dissipation design.
3.Do not use non-cotton materials to wipe the light guide plate
Always use a soft cotton cloth to clean the light guide plate. Non-cotton materials may scratch the surface or cause static, leading to dust buildup and reduced light performance.
4.Cleaning methods for dirt on the light guide plate surface
Dirt on the light guide plate surface primarily includes dust, fingerprints, and water stains left after casting. Here’s how to clean it: Soak all cotton cloths in alcohol to remove the dirt;
After wiping with alcohol, allow it to air dry or blow dry. Otherwise, residual moisture on the light guide plate surface may cause bright spots when it comes into contact with reflective materials or images;
If the dirt on the light guide plate surface is not very noticeable, it is recommended not to wipe it, as improper cleaning methods may cause new scratches;
Light guide plates are prone to static electricity and dust accumulation, and are difficult to clean.
5.Scratch Removal Methods for Light Guide Plate Surfaces
Basic knowledge for removing scratches from light guide plate surfaces:
Shallow scratches can be wiped with alcohol to reduce their visibility;
Deep scratches can be polished using an electric roller [cloth roller], which is a common method for acrylic related products.
6.Measures to compensate for defects on the surface of the light guide plate
If dirt and scratches on the surface of the light guide plate are difficult to handle, or if the handling process may affect the overall management efficiency of the company; the following methods can compensate for defects caused by issues on the surface of the light guide plate:
- For example, there is a certain spatial distance between the display screen of a lightbox or exhibit and the light guide plate. After installing the screen, defects on the light guide plate are generally not visible.
- For particularly light-colored images or images that are tightly adhered to the light guide plate, a diffusion film must be applied to the defective light guide plate. This generally completely compensates for surface issues on the light guide plate.
