The DMG48270C043_04WTR is a 4.3 inch, 480 x 272 TTL/RS232 HMI LCD display developed by DWIN with resistive touch, 16 MB of flash, a buzzer and an SD interface. It is based on DWIN's self-designed T5L0 chip, which drives a 16.7 million colour (18-bit) TFT panel.
The maker describes it as easy to use with DWIN's DGUS V7.624 GUI development tool, which needs no coding skills.
The display area is 95.04 x 53.86 mm, the viewing angle is 70/70/40/30 degrees (a TV-type view), the brightness is 230 nit and the power supply is 5 V at 1 A DC. It has a 3 V passive buzzer, an SD interface in FAT32 and a TTL/RS232 serial port. The LCD connects with a 40-pin 0.5 mm FPC (RGB interface), and power and serial share a 10-pin 1.0 mm latching socket. The unit weighs 115 g.
HMI displays run their own screen software, so your microcontroller only sends short serial commands. Design the pages in DWIN's DGUS tool, copy the files to a FAT32 SD card to load them and test the display on a bench with a stable supply before you fit it into a product.
Product designers, students and integrators who need an affordable touch panel for a machine, meter or appliance.
Connect the power and serial lines with the latching socket, apply 5 V and check that the display shows its start-up page. Then send a test command from your controller, such as changing a text field, before you write the full program. Avoid pressing on the resistive touch panel with sharp objects, and clean it with a soft cloth.
