55EW5TF-A

What the LG 55EW5TF-A does for glass-facing spaces

The LG 55EW5TF-A is a 55-inch transparent OLED display built for signage that must keep the view behind it open. Because OLED pixels emit their own light, the stack carries no backlight unit and no liquid crystal layer, which is how the panel reaches 33% transparency with the P-Cap touch film fitted. Content appears to float over whatever sits behind the glass, and a touch layer lets visitors navigate it directly.

Key specifications that matter for planning

• Panel: 55-inch OLED, 1920 x 1080 Full HD, 16:9, with a 120Hz refresh rate and 1ms grey-to-grey response.
• Transparency: 33% when set up, with 3% haze and a 150,000:1 contrast ratio.
• Brightness: 150 nit at 100% APL and 400 nit at 25% APL, measured without the front glass.
• Touch: P-Cap film supporting up to 10 touch points, 3.5 mm typical accuracy and objects from Ø12 mm.
• Glass: 3 mm chemically strengthened, anti-reflective, shatter-proof front glass.
• Power: built-in power supply, 100-240V 50/60Hz, typical 171 W and maximum 280 W.
• Environment: operating temperature 0 °C to 40 °C, humidity 10% to 80%.

Where it fits in Qatar

In Msheireb or The Pearl, a retail unit with a glass frontage can use the panel to show offers and wayfinding without hiding the store interior from people walking past. A hotel lobby in West Bay could place it between the reception area and the lounge, so guests keep their sight lines while they browse. In Education City or a university atrium, it can present campus information on a glass partition that does not close off the room behind it.

What to plan before ordering

Start with the head measurements of 1225.5 x 832.9 x 7.0 mm and the separate signage box of 782.8 x 238.4 x 34.7 mm, which connects to the head through the supplied cables. The head weighs 14.6 kg, so a free site survey is a sensible first step to confirm the wall or partition structure and the cable route. The bezel is 7.9 mm on three sides and 144.5 mm at the bottom, which affects how the unit sits against a wall or partition.

The panel is designed for indoor, air-conditioned spaces within 0 °C to 40 °C. Qatar summer temperatures outside often exceed 45 °C, so keep the display and its enclosure away from direct exterior heat and confirm the ventilation plan with the SmartRooms Qatar team. The source data gives no IP rating for this model, so avoid outdoor or dust-exposed locations unless the environment has been confirmed.

Connectivity and software

The panel offers one HDMI input, a DisplayPort input and output, two USB 2.0 Type A inputs, a USB 2.0 Type B touch connection, and LAN, RS232C and IR ports for control. It runs webOS 4.0 with 16GB of internal memory and supports SuperSign CMS, SuperSign Control+, Connected Care and Crestron Connected for management. There is no built-in Wi-Fi and no built-in speaker, so plan audio and network connections from the start.
