Product Description

TXW550040N0-CTP | 5.46" Full HD MIPI LCD Display with Capacitive Touch

Product Overview

The TXW550040N0-CTP is a premium 5.46-inch TFT LCD display module featuring Full HD resolution (1080×1920 pixels) and integrated capacitive touch panel. Designed for high-performance applications, this IPS-type display delivers exceptional color accuracy, wide viewing angles, and responsive touch interaction through a robust 4-lane MIPI DSI interface.

Manufactured by Shenzhen Tianxianwei Technology, this display module combines cutting-edge display technology with reliable industrial-grade construction, making it ideal for handheld devices, industrial controllers, medical equipment, and consumer electronics requiring superior visual performance.

Key Features

Stunning Visual Performance

Experience crystal-clear imagery with 1080×RGB×1920 pixel resolution and 16.7 million displayable colors. The IPS (In-Plane Switching) technology ensures consistent color reproduction and full 178° viewing angles from all directions — eliminating color shift and contrast loss regardless of viewing position.

Integrated Capacitive Touch

The G+F+F (Glass + Film + Film) multi-touch structure incorporates the Goodix GT911 controller, delivering precise and responsive touch detection. I²C interface ensures seamless communication with host processors, while the dedicated interrupt and reset pins enable efficient power management and gesture recognition.

High-Speed MIPI Interface

Four-lane MIPI DSI high-speed differential signaling provides reliable, high-bandwidth video transmission with reduced EMI. This modern interface standard enables thinner cable designs and simplified PCB layouts compared to traditional parallel RGB solutions.

Robust Backlight System

Edge-lit LED backlight configuration features 15 high-efficiency white LEDs delivering 1200 cd/m² typical luminance. With 30,000-hour LED lifetime rating and external PWM dimming control, the module adapts seamlessly to varying ambient lighting conditions from bright sunlight to dark environments.

Environmental & Reliability

Operating Conditions

Working Temperature: -20°C to +60°C Storage Temperature: -30°C to +70°C Humidity Range: 20% – 90% RH (non-condensing)

Reliability Testing

This module undergoes comprehensive reliability validation including 96-hour high temperature storage (+70°C), 96-hour low temperature storage (-30°C), operating temperature cycling, and thermal shock testing (-20°C ↔ +60°C, 10 cycles). All tests confirm zero functional defects, no liquid crystal leakage, and maintained optical performance under stress conditions.

Interface Pin Configuration

The 40-pin FPC connector provides comprehensive system integration:

• Power rails: GND, IOVCC (1.8V), VSP/VSN analog supplies, CTP_VCC (2.8-3.3V) • MIPI DSI: 4 data lane pairs (D0±, D1±, D2±, D3±) plus clock pair (CLK±) • Touch interface: CTP_SDA, CTP_SCL, CTP_INT, CTP_RST • Control signals: RESET, TE (tearing effect), PWM (backlight dimming) • Backlight: LEDA/LEDK anode and cathode connections

All high-speed differential pairs support LP-11 low-power state for energy-efficient operation.

Power Sequence & Timing

The HX8399C driver IC requires specific power-on sequencing: VDD1/HS_VCC must stabilize before VSP/VSN activation, with minimum 1ms delays between stages. Hardware reset (RESX) must maintain low for ≥10μs after power stabilization, with complete initialization requiring 120ms before display-on commands.

Power-off sequence reverses this order, ensuring MIPI video packets terminate before supply removal to prevent image retention and driver damage.

Applications

• Industrial HMI panels and handheld terminals • Medical diagnostic displays and portable equipment • Smart home control interfaces • Automotive infotainment systems • High-end consumer electronics and gaming devices • Test and measurement instrumentation

Quality Assurance

Manufactured under ISO-certified processes with 100% inspection for critical defects including missing segments, short circuits, and optical uniformity. Inspection conditions follow standardized protocols: 1000±200 lux illumination, 30cm viewing distance, 45°±10° observation angle.

RoHS-compliant construction ensures environmental responsibility with lead-free materials throughout.
