This 5.0 inch HMI LCD display has 800 x 480 resolution, resistive touch, 16 MB flash, a buzzer, a real-time clock (RTC) and an SD interface, and is aimed at commercial-grade applications. An HMI (human-machine interface) display runs its own screen graphics, so your microcontroller only has to send short commands over a serial link.
It uses an IPS TFT LCD panel with 18-bit colour and a display area of 109.0 x 65.8 mm.
The viewing angle is 70/70/50/70 degrees (left/right/up/down) and the brightness is 200 nit. It runs from 12 V DC at 1 A, has a 3 V passive buzzer, an SD interface for FAT32 downloads at 4 Mb/s and TTL/RS232 interface. The unit weighs 260 g. The product name mentions RS485 as well, so check the connector for the exact serial options.
To build a screen, design pages in the manufacturer's software, load them to the display over SD, then send commands from your controller to change values and read touches. Keep the touch panel clean, and use a stable 12 V supply.
Developers of machine controls, meters and embedded devices who want a ready-made touch screen with its own memory and clock.
Give the unit a stable 12 V supply, keep serial cable runs short and use shielded cable where there is electrical noise. Mount the display so the touch surface is easy to reach and lit evenly. Test the screens on a bench with your controller before you fit the display into an enclosure.
