What is an Open Frame LCD Monitor?

An open frame LCD monitor is a bare-chassis industrial display — the LCD panel, backlight, controller board, and mounting brackets, but no outer casing. Instead of sitting on a desk or in its own housing, it is designed to be built into equipment: behind a kiosk facade, inside a gaming cabinet, behind an ATM shroud, or into an OEM machine panel. Because the host equipment supplies the enclosure, an open frame monitor integrates with minimal depth and cost.

AplusLCD supplies two open frame families that share the same integration standard: the cost-effective LH series (250-500 nits) for indoor machines and the high-brightness LD series (up to 1500 nits) with optional PCAP touch for semi-outdoor and sunlight-readable installations. Both are built from industrial-grade components rated for 24/7 operation, accept VGA/DVI/HDMI signals, and mount on standard VESA patterns. Since 2008 AplusLCD has shipped open frame displays to more than 50 countries, supporting every integration with engineering confirmation of panel, mounting, and interface fit.

LH vs LD Series: Which Open Frame Monitor Do You Need?

Selection starts with the ambient light around the machine. The LH series at 250-500 nits is the workhorse for indoor equipment — gaming machines, ATMs, self-service kiosks, POS terminals, and industrial control panels under normal room lighting. The LD series steps up to 1500 nits with IPS/VA wide-viewing-angle panels when the display will sit near a window, behind glass, under bright retail lighting, or anywhere sunlight can reach the screen — and adds optional PCAP multi-touch for interactive terminals.

Both families share the mounting standard: standard VESA patterns (75×75 mm or 100×100 mm) or custom brackets, front OSD buttons that stay accessible through a bezel opening, and VGA/DVI/HDMI signals routed into your cabinet. Depth stays minimal so the unit fits behind thin kiosk facades, and the -20°C to +70°C operating range covers unconditioned spaces such as arcade floors, transit shelters, and warehouse terminals.

Available Sizes & Interfaces

The LH family runs from 6.5" to 19"; the LD family from 7" to 19". Available single-size configurations are:

LH Series: 6.5", 10.4", 12.1", 15", 19"
LD Series: 7", 10.4", 15", 17", 19"

  • Video inputs: VGA, DVI, and HDMI input options on both families for easy system integration
  • Touch: display-only standard; optional PCAP multi-touch on LD series for interactive kiosk applications
  • Power: 12V DC power input available on many models
  • Controls: front OSD buttons for brightness, contrast, and color calibration
  • Mounting: VESA 75×75 mm or 100×100 mm patterns; custom brackets for OEM projects

Open Frame vs. Panel Mount vs. Rack Mount: Mounting Comparison

Open frame is one of four industrial mounting styles AplusLCD supplies. The deciding factor is where your display's protective front lives:

AspectOpen Frame MonitorPanel Mount MonitorRack Mount Monitor
MountingBehind a machine facade or inside an enclosure — no outer casingFlush into a panel cutout with a front-sealed bezelSlides into standard 19" rack rails
Front protectionProvided by the host enclosure (no front sealing)IP65-IP67 sealed front bezelOptional IP65 front panel
Best forKiosks, gaming, ATMs, embedded OEM buildsWashdown, marine, dusty industrial floorsControl rooms, server areas, SCADA
Touch optionOptional PCAP on LD series (behind your cover)PCAP through sealed glassOptional front glass

Choose an open frame monitor when you are building the equipment. Choose a sealed panel mount monitor when the display face itself must survive dust, spray, or washdown, and a rack mount monitor for 19" cabinets. Our industrial LCD monitor selection guide maps every mounting type to its application.

Frequently Asked Questions

What is an open frame LCD monitor?
An open frame LCD monitor is a bare-chassis display without an external enclosure, designed to be mounted inside kiosks, gaming machines, ATMs, or industrial control panels. It includes the LCD panel, backlight, controller board, and mounting brackets, but no outer casing.
What is the difference between LH and LD series?
The LH series offers 250-500 nits brightness with VGA/DVI/HDMI inputs at a cost-effective price point for indoor use. The LD series offers 250-1500 nits high brightness with optional PCAP touch, IPS/VA wide viewing angles, and is designed for semi-outdoor and sunlight-readable applications.
Can I get a sample before bulk order?
Yes, we accept 1 pc sample orders with no minimum order quantity. Sample lead time is typically 5-7 days. This allows you to evaluate fit, brightness, and interface compatibility before committing to volume.
What mounting options are available?
All open frame monitors feature standard VESA mounting patterns (75x75mm or 100x100mm). Custom bracket designs are available for OEM projects with specific enclosure requirements.
How do open frame monitors differ from panel mount and rack mount displays?
An open frame monitor is a bare chassis designed to be mounted behind a machine facade or inside an enclosure — the equipment front provides protection. A panel mount monitor instead carries its own front-sealed bezel (IP65-IP67) that is flush-mounted in a panel cutout for washdown, marine, and dusty environments. A rack mount monitor slides into standard 19" rack rails for control rooms and server areas. If you are designing a kiosk, gaming machine, ATM, or OEM equipment, open frame is normally the right starting point; see the mounting comparison below.
Can an open frame monitor be made sunlight readable?
Yes. The LD series open frame monitors reach up to 1500 cd/m² with optional IPS/VA wide-viewing-angle panels, which keeps on-screen content legible in glass-fronted kiosks, transit shelters, and semi-outdoor installations. For fully exposed outdoor front-facing displays that need a sealed front bezel as well as high brightness, a high-brightness panel mount monitor is the alternative — our engineers will confirm the best form factor for your cutout and ambient-light conditions.
