Project Overview
In response to rising safety standards in automotive markets, we engineered a tft lcd reversing camera solution featuring a 14″ automotive-grade display. This display is capable of receiving and presenting four separate camera feeds simultaneously—ideal for rear and side monitoring in commercial vehicles, buses, or heavy machinery.
Technical Challenge
- 디스플레이 형식: Ultra-wide 1920×720 resolution (24:9 aspect ratio) to fit split-screen layouts.
- Environmental Specs: Mechanically robust and thin (1.08 mm panel, PCBA thickness ≤ 3.2 mm) for dashboard integration.
- Visual Performance: High NTSC ≥ 70% color gamut and 8-bit (16.7 million colors) fidelity for clear, true-to-life visuals.
- System Compatibility: Normally-black TFT mode preferred for power efficiency and high contrast in both day and low-light driving conditions.

Engineering Approach
- Panel Selection & Validation
The horizontally elongated TFT panel provides an ideal canvas for quad-camera split display, reducing the need for optical distortion or complex remapping. - Mechanical Integration
Adhering to a slim profile (1.08 mm panel thickness, ≤ 3.2 mm total with PCBA), the module was tailored for flush mounting behind dashboard styling bezels. - Electrical & Video Interface
We engineered a robust video pipeline accepting RTSP/NTSC composite streams from four camera inputs, then processed via our display controller onto the TFT panel. - Optical Quality Tuning
Gamma calibration and NTSC color tuning were applied during production to ensure consistency, color fidelity, and visibility across high-transmission automotive-grade optical films.
System Architecture & Integration
To ensure seamless camera visualization, the system was designed with the following layered architecture:
- Input Layer
Four analog or digital camera feeds, compatible with NTSC or CVBS signals, routed to an onboard AHD decoder or external ADAS processor. - Processing Layer
Video streams synchronized and formatted by a custom video stitching or switching IC, depending on the selected view mode (quad-split, full-screen, or dual split). - Display Output Layer
Processed image rendered directly to the 14″ tft lcd reversing camera module via RGB or LVDS interface, depending on client ECU architecture. - Control Interface
Touch buttons or steering wheel-mounted triggers used to toggle views, initiate zoom, or enable parking guidelines overlay.
The integration workflow considered thermal dissipation, shielding for EMI/EMC robustness, and vibration-resistant FPC mounting.
User Experience Enhancements
The ultra-wide resolution and 70%+ NTSC color performance offer a clear advantage in real-world use:
- Improved Situational Awareness
The 1920×720 resolution supports real-time viewing of 4 cameras without downscaling, offering drivers precise distance judgment and object recognition. - Low-Reflection Display Performance
The normally black TFT mode reduces ambient glare, offering strong visibility during night driving or tunnel entry conditions. - Instant Wake & Response Time
Optimized driver ICs ensure sub-100ms screen wake and video display after reverse gear activation. - Flexible Mounting Options
Due to its slim form factor and custom PCBA layout, the module supports horizontal or angled integration within dashboard, center console, or A-pillar structures.
Environmental Reliability
The display solution passed multiple automotive-grade validations, including:
- Wide Temperature Operation: -30 °C to +85 °C
- ESD Protection: 8kV air / 4kV contact discharge
- Vibration Testing: Compliant with ISO 16750-3 standards
- UV and Humidity Resistance: 향상된 편광판 내구성

비즈니스 성과
이 tft lcd reversing camera 해당 모듈은 현재 동남아시아의 진행 중인 플릿 차량 플랫폼에 통합되었습니다. 주요 내용은 다음과 같습니다:
- 모듈식 PCBA + 패널 통합을 통한 시장 출시 시간 단축
- 2-카메라에서 4-카메라 설계로의 비용 효율적 전환
- 후방 시야성에 대한 최종 사용자 신뢰 및 규제 준수 강화
본 프로젝트의 성공을 통해 전기 배송 밴, 저속 도시 물류 차량, 그리고 자동차 용품 애프터마켓 키트에 유사한 플랫폼을 적용할 수 있게 되었습니다.
