- Effective light-shielding design: The hood provides a light-shielding distance of 17 cm to minimize ambient light interference with display colours, so the colours appear closer to real. The inner surface uses black matte material to absorb reflections. Combined with bamboo charcoal powder, it enhances shielding of radiation and absorption of harmful gases. - Foldable design: The side panel and top panel connect with a foldable joint and a spring. The spring pressure strengthens the connection between the hood and the display stand, allowing it to be firmly covered on the stand without additional connection facilities. - Radiation protection design: Bamboo charcoal powder is placed in the middle of the inner panel. It can shield electromagnetic waves through fabrics and absorb harmful gases and smoke particles emitted during computer use, protecting the user’s eyes, facial skin and health. - Disassembly-free design: To use, open the side panel to adjust the width. When not in use, simply remove it. Both side panels automatically close. Small and portable, with adjustable width to fit 17-28 inch monitors.
