Ordering and Custom Builds
The MLT043R45-R1 is available for sampling and volume orders. For datasheets, technical support, or to place an order, please use the inquiry button on this page or contact our sales team. See also our 4.3 inch tft range for the broader part number set, and the sunlight readable guide for how transflective compares to high brightness transmissive builds.
What does "transflective" mean on this 4.3 inch size?
Transflective panels combine a transmissive backlight with a reflective layer, so the display is readable both indoors (backlight on) and in direct sunlight (ambient light reflected). On the 4.3 inch diagonal this is the most common pick for outdoor HMIs and handheld instruments.
Why use SPI plus RGB together on the MLT043R45-R1?
SPI handles command initialisation with only four pins, which keeps the host side simple. RGB then streams the 480x272 pixel data at high speed, so animations and full-screen updates are smooth. This split is widely used in STM32, ESP32-S3 and i.MX RT projects.
Can this display run at -30 to +85 degrees Celsius?
Yes, the ST7701S driver and the panel are both qualified for -30 °C to +85 °C. We use this build in outdoor signage and industrial control products with no special derating.
What can be customised on the 4.3 inch transflective TFT?
Common changes are FPC length and pinout, the connector type, cover glass and backlight brightness. We can also quote a resistive or capacitive touch panel bonded to the same 4.3 inch glass. Send your requirements and we will confirm feasibility with a drawing within one working day.
