7.0 Inch 1024x600 RS232 HMI LCD Display with Resistive Touch (16MB Flash, SD, Buzzer)

A resistive 7 inch HMI for industrial use

This 7.0 inch HMI LCD display has a 1024 x 600 IPS panel, RS232 communication, resistive touch, 16 MB of flash, an SD interface and a buzzer. It is designed for human-machine interface applications, and it is easy to set up with DWIN's DGUS V7.6 GUI development tool, which needs no coding skills.

The display is based on DWIN's self-designed T5L2 ASIC and shows 16.7 million colours (24-bit).

Specifications

The display area is 156.00 x 88.20 mm, brightness is 250 nit, the supply is 5 V at 1 A DC and the unit weighs 250 g. The viewing angle is 85 degrees in every direction, the SD interface uses FAT32 and the buzzer is a 3 V passive type. One feature line quotes an 800 x 480 pixel figure while the title and specification give 1024 x 600, so rely on the 1024 x 600 figure.

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.

Who it is for

Integrators who want a resistive touch screen that works with gloves in workshops and factories, connected through RS232.

Working in a workshop

Resistive touch works through gloves and with a stylus, so it is a good choice for a machine panel. Calibrate the touch once if the pointer seems off, protect the screen from swarf and liquids and keep the supply stable. Use the buzzer to confirm button presses so an operator knows the touch was registered.
