Introduction

AI Translation

TM1721 is a dedicated LCD driver control IC with keyboard scan interface, integrating MCU digital interface, data latch, LCD driver, keyboard scan, and RGB backlight driver circuits. This product delivers excellent performance and reliable quality, requiring no modification to the decoder board's low-level instruction set — fully compatible with existing 3-wire LED driver IC instruction sets. Existing decoder boards that support LED displays can directly interface with an LCD front panel without requiring an external MCU for key scanning (or key scanning via the decoder board), and no additional HT6221 is needed for key scanning. Supports both PWM backlight driving and SW general-purpose input expansion ports. Primarily used in display panel driving for VCR, VCD, DVD, and home theater products.
