Host and touch
The LCD has a 24-bit RGB + SPI connection; do not treat it as an SPI-only graphics display. Capacitive touch uses I²C on a separate FPC.

02 / DESIGN-IN CHECKS
Plan the integration.
Mechanical fit
The 76.96 × 63.96 mm body excludes FPC tails. The 4.70 mm nominal thickness includes touch. Allow separate space for cable routing.
Optical and electrical conditions
850 cd/m² is a typical drawing value without a stated measurement position or test condition. The LED annotation of 19.2 V at 40 mA is separate from that luminance value.
03 / APPLICATION IDEAS
Applications to evaluate.
Suggested contexts require system validation.
Equipment controls
Check the RGB host, touch-target layout at 320 × 240 and enclosure aperture.
Instruments
Evaluate text size, viewing position and the assembled optical stack.
