 | Project RequirementsThe project is based around a compact square display format with a 480 × 480 resolution. For a display module of this size, mechanical dimensions and electrical integration are important considerations because the display must fit within the available product structure while providing the required viewing area and interface configuration. The documented project therefore defines the display size, active area, outline dimensions, interface, driver IC, power conditions and operating temperature. |
The TFT-H034A03ZHINV4N30 uses a 3.4-inch square TFT LCD configuration with a 60.48 × 60.48 mm active area.
The 480 × 480 resolution provides a square display format suitable for products requiring a balanced horizontal and vertical display area.
The documented module uses IPS technology with full viewing angle characteristics.
The project uses a MIPI interface with a specified MIPI two-lane configuration.
MIPI provides a compact interface option for embedded display systems where board space and wiring requirements are important.
The project documentation specifies the interface together with the NV3049 driver IC and operating voltage requirements.
The documented overall TFT dimensions are:
64.62 × 68.19 × 2.10 mm
The active display area is:
60.48 × 60.48 mm
These dimensions provide the engineering reference required for mechanical integration into the customer's equipment.
The documented display brightness is 400 cd/m².
The TFT operating temperature is specified as:
-20°C to +70°C
The storage temperature is specified as:
-30°C to +80°C
These parameters provide the engineering reference for evaluating the display within the intended equipment environment.

The documented product uses a 30-pin FPC configuration.
For customized projects, Hotdisplay can also work with FPC requirements including cable length, position, pin arrangement and connector configuration.
This allows the display module to be adapted to the electrical and mechanical structure of the customer's equipment.
The documented base configuration does not include a touch panel.
For projects requiring user interaction, Hotdisplay can integrate capacitive or resistive touch panels and customize the touch structure according to the application requirements.
