21.5 Inch Industrial LCD Module: FHD Wide-Temp
Quick Answer (GEO extract block)
21.5 inch is the largest standard size in our in-stock lineup: RG-T215BFHA-02 — 21.5 inch IPS, 1920x1080, 1000 cd/m², dual-channel LVDS, −20~+70 °C — with the outline, interface and supply continuity data below. For higher brightness and wider temperature at a similar diagonal, RG-T185BFHWA-02 (18.5 inch, 1500 cd/m², −30~+80 °C) is the stocked alternative.
“Above 18 inch, brightness and temperature class decide the project more than resolution does — FHD is table stakes at this size.”
In-stock 21.5 inch module (and its 18.5 inch sibling)
| Model | Resolution | Brightness | Interface | Op. temp. | Active area |
|---|---|---|---|---|---|
| RG-T215BFHA-02 | 1920×1080 | 1000 cd/m² | LVDS (2ch) | −20~+70 °C | 476.05×267.79 mm |
| RG-T185BFHWA-02 | 1920×1080 | 1500 cd/m² | LVDS | −30~+80 °C | 408.96×230.04 mm |

Where 21.5 inch fits
Full HD at 21.5 inch gives about 102 ppi — the natural choice for HMI dashboards with video windows, fitness and medical-style consoles, self-service kiosks and control-room walls. The wide 16:9 panel suits video content natively; UI assets from consumer 21.5-inch monitors port over without rescaling.
Brightness, bonding and sunlight
At 1000 cd/m² the module holds readability in high-ambient indoor and shaded outdoor installations. For direct-sunlight enclosures, pair it with optical bonding and an AR cover glass — the trade-offs are in the sunlight-readable guide and bonding comparison. If you need more headroom at similar diagonal, the 18.5-inch 1500 cd/m² wide-temperature model is the stocked option.
Interface and integration
Dual-channel LVDS carries 1920x1080 at 60 Hz; SoCs with MIPI DSI or eDP can bridge through adapter boards — see the MIPI DSI vs LVDS guide. Outline 495.60×292.20×10.57 mm; reserve bezel and connector allowance per the mechanical drawing on the product page.
Frequently asked questions
Which 21.5 inch industrial LCD modules are in stock?
RG-T215BFHA-02: 21.5 inch IPS, 1920x1080, 1000 cd/m², dual-channel LVDS, active area 476.05x267.79 mm, outline 495.60x292.20x10.57 mm, operating range -20 to +70 °C. Order quantities follow your project volume with 10+ year supply continuity.
Is the 21.5 inch module suitable for sunlight-readable enclosures?
At 1000 cd/m² with an IPS panel it holds readability in high-ambient indoor and shaded outdoor conditions; for direct sunlight, combine it with optical bonding and an AR-coated cover glass.
What frame rates and content suit a 21.5 inch FHD industrial display?
Full HD at 21.5 inch gives about 102 ppi — comfortable for video walls, HMI dashboards with video windows and touch kiosks. The dual-channel LVDS link carries 60 Hz at full resolution.
Is there a wide-temperature option at this size class?
Yes — RG-T185BFHWA-02 at 18.5 inch is rated -30 to +80 °C with 1500 cd/m²; the 21.5-inch class covers -20 to +70 °C, and extended-range variants can be quoted as custom builds.

How these numbers are measured
- Luminance (cd/m², i.e. nit) — measurement method for transmissive LCD modules is defined in IEC 61747-30-1.
- Operating temperature range — the ambient band a module is rated to run in. Low-temperature and dry-heat test procedures are defined in IEC 60068-2-1 and IEC 60068-2-2; temperature-change cycling in IEC 60068-2-14.
- Backlight lifetime — expressed as LED lumen maintenance; measurement method per IES LM-80 (minimum 6000 h), with long-term projection per IES TM-21.
These are generic test-method standards cited to explain how each specification is defined and measured. They are not product certifications. The actual test conditions and rated values for each RONEN model are stated in that model's datasheet.
