Z040-40RH-A1 product introduction
Z040-40RH-A1 is a 4-inch square tft-lcd display with 480 × 480 resolution and a 3SPI+RGB interface. Review the module specifications, product images and integration requirements before requesting a sample. The square tft displays format helps define the display area and user-interface layout while the exact model reference keeps the optical, electrical and mechanical requirements tied to one assembly.
Module Dimensions: 84 × 84 × 3.05 mm. Brightness: 400 cd/m². Touch: Capacitive Touch Panel. Operating Temperature: -20 to 70 °C. Use these published characteristics to compare Z040-40RH-A1 with the requirements of your equipment. Brightness, viewing direction and touch operation should be evaluated in the intended enclosure, lighting and user environment.
The 3SPI+RGB connection on Z040-40RH-A1 should be checked against the host controller and connector arrangement. Review supply levels, backlight drive, cable routing and the matching pin assignment before connecting a sample. A shared interface name alone does not establish compatibility between two modules.
