Rutronik offers the 3.9 inch PCAP TFT display RFS390Q-EIW-DBG from Raystar. It has a resolution of 480x128 pixels and supports the digital MPU 8bit/16bit interface. With a luminance of 400 cd/m² at a contrast ratio of 500:1 and an LED service life of 50,000 hours, the TFT display is ideal for many smart home and industrial applications, according to the supplier. The touchscreen is controlled by a CYTMA568 multi-touch controller and enables reliable and precise inputs. Pins 33 - 36 on the connector have already been predefined for the white LED backlight, so no specially designed circuit is required. The entire module has dimensions of 122 x 44 x 9.8mm, the active area itself measures 95.04 x 25.34mm. Due to its similar dimensions, the RFS390Q is an ideal upgrade solution for the 16x2 mono character LCD display family RC1602E, which has neither colors nor a touch function.
