TFT LCD 모듈 선택법: 엔지니어 가이드
크기, 해상도, 휘도, 터치, 온도 범위, 인터페이스를 다루는 TFT LCD 모듈 선택 실용 가이드. DISEA 표준 모델로 설명합니다。Start With the Application, Not the Spec Sheet
The same 4.3-inch panel can be perfect for a wall-mounted thermostat and useless for a forklift terminal. Before comparing specs, write down where the display will live: indoor or outdoor, viewed for seconds or hours, operated bare-handed or with gloves, running 8 hours a day or 24/7 for a decade.
- Indoor instruments and POS — standard brightness, cost-effective TN or entry IPS
- Outdoor and semi-outdoor HMI — high brightness plus optical bonding
- Vehicles and cold storage — wide temperature is non-negotiable
- Handheld and wearable — small size, low power, SPI interface
Size and Resolution: Match Pixels to Viewing Distance
Pick resolution for viewing distance, not for the biggest number. A 480×272 panel is fine on a 4.3-inch HMI read at arm's length; a 10.1-inch monitor read at 40 cm wants 1024×600 or more. As a rule of thumb, aim for 100–150 PPI at the working distance — beyond that, the eye stops resolving the gain and you only pay for it.
DISEA offers 40+ resolution combinations, from 128×115 on a 0.99-inch round glass up to full-HD-class panels, so the resolution you need usually exists as a standard part rather than a custom project.
Brightness: Indoor, High-Bright and Sunlight Readable
Most indoor modules sit between 250 and 500 cd/m² — enough for controlled lighting, and it keeps power and cost down. Once a display faces windows, shop floors or daylight, move up deliberately:
| Environment | Typical requirement |
|---|---|
| Indoor, controlled lighting | 250–500 cd/m² |
| Indoor, near windows / bright floor | 600–1000 cd/m² |
| Outdoor, shaded | 1000–1500 cd/m² |
| Outdoor, direct sunlight | 1500+ cd/m² with anti-reflection treatment |
Our catalog currently includes 23 models rated at or above 1000 cd/m² — see the linked list at the end of this guide.
Touch: None, Resistive (RTP) or Capacitive (CTP)
No touch is still the right answer for read-only indicators. Resistive touch wins on cost, works with any stylus and with gloves, and tolerates water droplets. Capacitive (PCAP) delivers the smartphone-grade experience end customers now expect: multi-touch, high clarity and a flush glass surface. 35 of our standard models ship with PCAP touch already bonded at the factory.
Operating Temperature and Long-Term Supply
Standard panels are typically rated 0 to +60 °C — fine for indoor electronics. Freezers, outdoor cabinets and vehicle bays need modules rated −30 °C to +85 °C; we stock 33 such models. Finally, confirm supply continuity for industrial projects: DISEA keeps standard products in production for 5–8 years, selected parts beyond 10 years, so your BOM outlives the product cycle instead of forcing a costly redesign.
