The type of paint used to paint the bezel behind the LCD can vary depending on the specific device and manufacturer. However, in most cases, a type of paint known as "plastic paint" or "plastic primer" is commonly used for painting plastic surfaces, including the bezel.
Plastic paint or plastic primer is formulated to adhere well to plastic surfaces and provide good coverage and durability. It typically comes in aerosol spray cans for easy application. You can find plastic paint or primer specifically designed for automotive use or general-purpose plastic paints available at automotive supply stores, hardware stores, or online.
Before applying the plastic paint or primer, it's essential to properly prepare the surface by cleaning it thoroughly and removing any dirt, oils, or previous coatings. Lightly sanding the surface with fine-grit sandpaper can also help improve the adhesion of the paint.
When applying the plastic paint or primer, follow the manufacturer's instructions regarding the recommended distance for spraying, number of coats to apply, and drying time between coats. It's important to work in a well-ventilated area and wear appropriate personal protective equipment.
By using a plastic paint or primer designed for adhesion to plastic surfaces, you can achieve a durable and long-lasting finish on the bezel behind the LCD.
