4.3" 480x272 IPS TFT SPI Interface for STM32, ESP32, MCU, HMI

Description

ER-TFT043A5-3 is a 4.3-inch IPS TFT LCD display with a 480×272 pixel wide format (95.04×53.86 mm active area, 98.32×56.70 mm visual area, 105.42×67.07×3.0 mm with FPC folded). The IPS cell gives a true 80°/80°/80°/80° viewing cone, 65K / 262K color depth, a 1000:1 typical contrast ratio, and 300 cd/m² brightness, so embedded GUIs, status pages, and instrument readouts stay consistent from any angle.

ER-TFT043A5-3 integrates the NV3041 controller in COG packaging and is unusually flexible on the bus: IM0–IM2 select 8080 8/9/16-bit parallel (DB0–DB15), 4-wire SPI (SDA/SCL/CS/RST/RS), Dual SPI (SDA + RS_SDO2), or Quad SPI (SDA + RS_SDO2 + DB0 + DB1). That makes it friendly to both parallel-bus MCUs (STM32 FSMC, 8051 with glue logic) and low-pin hosts (ESP32, Pi Pico, small STM32 over Quad SPI). Logic runs at VDD 3.0–3.3 V typ, 3.6 V max; IO abs max is 4.6 V. Response time is 30 ms.

The backlight is a 12-chip white LED string: Vf 2.8–3.2 V typ 3.0 V at 240 mA, typical drive 200 mA, 30,000-hour life at 180 mA / 25 ℃ (LEDA/LEDK on the 30-pin FPC). ER-TFT043A5-3 is offered with an optional capacitive touch panel ER-TPC043-2, whose controller talks I²C over a 6-pin FPC (SCL, SDA, VDD, RST, INT, GND) for finger/multi-touch input.

We provide NV3041 demo code, 8080/SPI/Dual-SPI/Quad-SPI examples, and wiring references for STM32 (FSMC or SPI/QSPI), ESP32 (QSPI/SPI), 8051, and Raspberry Pi on buydisplay.com. As with all TFT panels, avoid a fixed image longer than 2 hours to prevent image sticking (reversible by running an all-black pattern for 4–6 hours, per Section 8).

Rated for −20~+70 ℃ operating and −30~+80 ℃ storage, ER-TFT043A5-3 is an indoor industrial/consumer panel. It is not sunlight-readable.

That is suitable for a wide range of applications, including industrial control panels, test-equipment screens, smart-home consoles, POS aux displays, handheld instruments, and any MCU/SBC project that wants a 4.3-inch IPS screen with both parallel and SPI/QSPI wiring options plus optional I²C capacitive touch.
