General Description
The LSC0395I12-MP-V1 is a high-quality square display module featuring a balanced 480x480 resolution suitable for user interfaces, medical imaging, or industrial dashboards. The IPS panel guarantees wide viewing angles and consistent color. The module utilizes a 2-lane MIPI DSI interface, a high-speed serial interface that reduces EMI and connector size compared to parallel interfaces.
The specification includes a clear pin description table for its connector, detailing the differential data/clock pairs, power pins (VCC, IOVCC, GND), and control pins like RESET and TE. A dedicated MIPI timing characteristics section defines parameters for High-Speed mode, such as the UI (Unit Interval) instantaneous time and data-to-clock setup/hold times (tDS, tDH), which are crucial for reliable high-speed signal integrity.
