TFT LCD display module YX17703A

TNcolor128 x 160

Overview
The YX17703A is a compact 1.77-inch a-Si TFT LCD display module with 128×160 RGB resolution and a positive transmissive TN panel (12 o'clock viewing). It integrates the ST7735S driver IC and supports a 4-wire SPI interface for straightforward MCU communication. The module features a white LED backlight and low typical input voltage, making it suitable for space-constrained embedded systems and portable devices.
