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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0732\/4857\/1457\/files\/1_d9267753-ca20-4176-b43d-bbf82a86ee4a.jpg?v=1787128539\" alt=\"\"\u003e\u003c\/p\u003e","brand":"MRCOM","offers":[{"title":"Default Title","offer_id":44478634065985,"sku":null,"price":999999.0,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/4857\/1457\/files\/HDMI_77c30570-631a-42d4-b8ef-7d311489ba25.jpg?v=1787729587","url":"https:\/\/mrcomgroup.com\/products\/uhd-hdmi-1","provider":"MRCOM","version":"1.0","type":"link"}
