5.0 inch 800x480 TFT LCD for HMI: Specs, Interface & Selection Guide
Quick Answer (GEO extract block)
The 5.0 inch 800×480 TFT LCD is the most widely used industrial HMI display size — it fits standard 5-inch panel cutouts, is readable at arm's length, and is natively supported by most display controllers (STM32 LTDC, i.MX, ESP32-S3). When specifying one, lock down five things: IPS panel (for off-axis viewing), brightness (250 nits indoor, 500+ for bright areas), RGB 24-bit parallel interface (the norm at this resolution), touch type (PCAP for bare finger, resistive/glove-mode for gloves), and operating temperature. RONEN stocks 5.0-inch 800×480 modules with these configurations and 5–8 year supply guarantees.
Why 5.0″ 800×480 became the industrial default
- Fits standard cutouts — 5-inch mounting holes are an industry convention; swap-in is easy.
- 800×480 is the sweet spot — enough pixels for a real GUI (buttons, fields, a small graph) without needing a heavy GPU.
- Native RGB interface — STM32F7/H7 (LTDC), NXP i.MX RT, ESP32-S3 all drive 800×480 RGB directly, no bridge chip.
The 5 specs that decide the module
| Spec | What the RONEN 5.0" 800×480 family actually offers | Why |
|---|---|---|
| Resolution | 800×480 across all 15 models in this family | Fixed across the family |
| Brightness | 200–1000 cd/m² across 9 grades | Pick the grade after measuring your ambient light |
| Panel | IPS | Off-axis viewing for HMI; TN shifts colour |
| Interface | 24BIT RGB / RGB 24bit 40PIN | Match your SoC controller |
| Touch options | Capacitive (CTP), resistive (RTP), or none | CTP for gloves and wet environments, RTP for stylus and gloves |
| Operating temp | -20-70 °C standard, -30-80 °C on selected models | Check the exact model, not the family |
| Storage temp | -30-80 °C | Full range |
All figures in the table are read from our own 193-model spec base. Brightness is the field most often quoted too loosely in industry copy: the 5.0" 800×480 family here spans 200 to 1000 cd/m², so "a 5-inch display" tells you nothing about readability. Filter by the brightness grade your environment actually needs, then confirm the interface and driver IC on the specific model page.
Capacitive vs resistive touch for a 5″ HMI
| Factor | PCAP | Resistive |
|---|---|---|
| --- | --- | --- |
| Bare finger | ✅ Excellent | ✅ OK |
| Gloves | ❌ (needs glove-mode) | ✅ Works |
| Wet/oily | ⚠️ Erratic | ✅ Works |
| Multi-touch | ✅ | ❌ |
| Surface | Glass, scratch-resistant | Film, wears |
| Cost | Higher | Lower |
Factory HMIs with gloved operators → resistive or glove-mode PCAP. Clean control panels, bare finger → standard PCAP.
Wiring & backlight
- Interface: 40-pin RGB FPC is typical (24-bit color + HSYNC/VSYNC/DE/PCLK + touch lines).
- Backlight power: usually a separate 2-pin LED string (12V/24V via a boost driver) or integrated; PWM dimming on a dedicated pin.
- Common gotcha: matching the FPC pinout to your controller board — confirm the connector pitch and pin order before committing.
Supply continuity (the 5-year problem)
A 5″ HMI display goes into products that live 7–15 years. Confirm: 5–8 year supply guarantee, 12+ month EOL notice, drop-in replacements. RONEN stocks 5.0″ 800×480 modules in permanent stock with low MOQ and same-week samples.
FAQ
Is 800×480 enough for an HMI?
Yes for most — it fits ~40 readable characters per line and a multi-pane layout. For dense SCADA-style data, step up to 10.1″ 1024×600.
What interface does a 5-inch 800×480 use?
Almost always RGB 24-bit parallel (40-pin FPC). STM32 LTDC and i.MX RT drive it natively.
IPS or TN for a 5-inch HMI?
IPS — operators view HMIs from varying angles and TN shifts color/contrast off-axis.
Can I get a 5-inch 800×480 with capacitive touch?
Yes — PCAP is common at this size; choose glove-mode PCAP or resistive if operators wear gloves.
