**Premium Custom UHD Ultra+OC Series with PWM+PAM**

The fundamental innovation of PWM+PAM hybrid driving lies in extending grayscale generation from the "one‑dimensional time duty‑cycle" to a **two‑dimensional expression of time × current**. Instead of relying solely on extremely narrow pulse widths to achieve higher brightness‑control precision, it builds the brightness implementation mechanism through real‑time switchable current levels (PAM) and duty cycles (PWM). It represents a new‑generation driving technology compared with conventional PWM driving.
