This is the most significant difference. OD LED Indoor screens typically have a much smaller pixel pitch like 1.5mm, P1.8mm, P2.5mm, P3mm A smaller pixel pitch means the individual LEDs are closer together, resulting in a higher pixel density and a clearer, more detailed image, even when viewed from a close distance. This is crucial for environments where viewers are often just a few feet away, indoor displays operate in controlled lighting conditions. Their brightness levels typically range from 500 to 1,500 nits. This is sufficient for indoor visibility and helps prevent glare, eye strain, and excessive power consumption.

OD LED Indoor screens offer very wide viewing angles (e.g., 140° to 160° or more). This ensures that the image remains consistent in color and brightness even when viewed from extreme off-angles, which is important in large lobbies, auditoriums, or retail spaces, Indoor LED panels are designed to connect without visible bezels or gaps, creating a truly seamless and expansive visual canvas. Indoor panels are often much thinner and lighter than outdoor ones, making them easier to install on walls, hang from ceilings, or integrate into architectural features without requiring massive structural support.
