Open Frame LCD Design for Embedded Applications

Open frame LCDs are popular in embedded, industrial, and commercial display solutions where integration flexibility is a priority. Unlike enclosed displays, open frame modules expose the key components—TFT panel, controller board, and mounting brackets—allowing engineers to embed them directly into custom housings or cabinets.

1. What Is an Open Frame LCD?

An open frame LCD is a semi-finished display unit that provides structural mounting points while leaving the enclosure design to the end application. It typically includes:

• TFT LCD panel (with or without touch)
• Mounting bezel or brackets
• Integrated driver board (HDMI, VGA, MIPI, etc.)
• Optional back housing or metal support frame

2. Benefits of Open Frame Design

• Easy to embed in kiosks, control panels, vending machines, etc.
• Cost-effective when the end product already has its own enclosure
• Supports modularity and easy upgrade paths
• Customizable in size, interface, mounting method

3. Applications

Open frame LCDs are widely used in:

• Self-service terminals and ATMs
• Industrial automation HMIs
• Gaming machines and POS systems
• Medical diagnostics and cleanroom displays
• Smart access control panels and RFID kiosks

4. Customization Options

Rocktech offers full customization of open frame modules including:

• Touch panel integration (resistive, capacitive, optical bonding)
• Different mounting formats: VESA, side brackets, screw holes
• Backlight tuning (brightness, power)
• Interface choice: HDMI, VGA, LVDS, USB, UART
• Optional cover glass, coating, EMI shielding
• RFID pass-through design: In certain use cases, cut-outs in the backlight's metal frame can be introduced to allow RFID signals to pass through the TFT-LCD area. This enables card scanning directly on the screen surface without compromising display performance.
