Tianxianwei Unveils MIPI-Enabled 4.0-inch TFT for Embedded Systems

Next-Generation High-Density TFT Technology: Redefining Compact Industrial Interfaces‌

Shenzhen Tianxianwei Technology Co., LTD's latest TXW400012B0 4.0-inch TFT LCD module represents a breakthrough in ultra-high-density display solutions for embedded applications. Based on a ‌4-lane MIPI interface‌ architecture and driven by the ‌NV3051F integrated circuit‌, this module delivers a pixel density of ‌720(RGB)x720‌ resolution within an active display area measuring ‌101.52×101.52mm‌, achieving a 5:4 aspect ratio.

1. ‌Advanced Display Core‌: The module features a ‌Normally Black TFT active matrix structure‌ with ‌RGB vertical stripe‌ pixel arrangement, enabling 16.7 million color depth selection through software configuration. The optical performance includes ‌ALL O'CLOCK viewing direction‌ characteristics with standard brightness parameters currently pending validation.

2. ‌Environmental Performance‌: Designed for industrial applications, the module maintains operational reliability within an extended temperature range of ‌-20°C to +70°C‌ with storage capacity from ‌-30°C to +80°C‌. Humidity tolerance is specified at 90% RH maximum.

3. ‌Optoelectronic Architecture‌: The backlight system incorporates ‌edge-lighting technology‌ with 8 white LEDs requiring ‌22.4-25.6V forward voltage‌ at 40mA current, achieving typical luminance outputs. The electroluminescent source exhibits a calculated lifecycle rating at optimized operating parameters.

4. ‌Power Management System‌: The module implements dual-power domain architecture, with I/O circuitry operating at ‌1.65-3.3V‌ and core DC/DC conversion requiring ‌2.7-3.6V‌ input. Current consumption remains below ‌100mA‌ in active mode, with sleep-state consumption reduced to 150μA.

‌Signal Interface Implementation:

‌

• ‌High-Speed Data Transmission‌: The MIPI-DSI interface utilizes four differential data lane pairs (D0P/D0N through D3P/D3N) with dedicated clock signal pairs (CLKP/CLKN), ensuring compatibility with advanced SoC platforms.

• ‌Ancillary Signal Integration‌: Reset and Tearing Effect (TE) outputs provide display synchronization control, while PWM dimming input enables adjustable backlight intensity modulation.

• ‌Expansion Interface‌: The system provides capacitive touch panel integration capability with dedicated I²C interface pins (CTP_SDA/SCL), interrupt notification (CTP_INT), and isolated power rails (CTP_VCI).

The module's physical construction incorporates precision mounting techniques including silver paste dots and single-layer conductive adhesive elements, ensuring thermal and mechanical stability in challenging operating environments.

For engineers requiring high-resolution display technology with minimal footprint, this MIPI-enabled module provides a technically advanced solution compatible with next-generation embedded systems.
