LED Grayscale Bit Depth: 8–16 Bit Differences, Driver ICs, Dithering and On-Site Tests

Grayscale bit depth determines whether dark gradients show visible banding or roll smoothly. This document explains the meaning of hardware bit depth, where it becomes visible, how dithering can hide a lower hardware figure, a driver-IC reference, on-site verification steps, and a recommended tender specification. What grayscale bit depth actually measures Each LED channel (R, G, B) is driven by a driver IC using PWM. The duty-cycle resolution of that PWM is the grayscale bit depth — the number
