General Description
The LS0395I15-MP-V1 is a premium square display module featuring high pixel density and excellent visual performance. The IPS panel guarantees consistent color and wide viewing angles. The module utilizes a MIPI DSI interface, a high-speed serial interface standard that reduces EMI and connector size, suitable for modern application processors.
The specification includes a detailed pin description table for its connector, listing pins for the MIPI differential data lanes (D0N/D0P, D1N/D1P, etc.), clock pair (CLKN/CLKP), power (GND), and backlight (LEDA, LEDK). The electro-optical characteristics table is well-defined, covering key metrics like response time, contrast ratio, transmittance, white point, viewing angles, and luminance. Mechanical notes provide important design guidelines, such as recommending the housing opening be at least 0.3mm smaller per side than the active area and ensuring the backlight foam gasket opening is >0.6mm larger.
