The LG 55EW5TK-A is a 55-inch transparent OLED touch display, now discontinued by LG. Its 33% transparency lets content overlay what sits behind the glass, and its P-Cap touch layer supports up to 10 touch points. Suited to retail windows, showrooms and lobby counters in Doha, Lusail and West Bay where products should stay visible. Owners and buyers seeking a current equivalent can request a quote.
What the LG 55EW5TK-A does in a glass frontage
The LG 55EW5TK-A is a 55-inch transparent OLED signage display from LG's EW5 series, fitted with a P-Cap touch film. LG has discontinued this model, so this page is written for organisations that already own one, buyers comparing it with newer transparent displays, and anyone looking for a current equivalent. SmartRooms Qatar can quote for a compatible replacement.
Specifications that shape the buying decision
The panel is an OLED with a native 1920 x 1080 resolution and a 16:9 aspect ratio. Transparency is rated at 33% with the touch film in place, which lets people walking past see the room or shop interior behind the content. Brightness is listed at 150 nits at full-picture level and 400 nits at 25% APL, measured without the protective glass, and the contrast ratio is 150,000:1. The image is self-lit, so colours stay clear against the background. The refresh rate is 120Hz with a 1ms grey-to-grey response.
Touch uses a P-Cap film connected over USB 2.0 Type B. It supports up to 10 simultaneous touch points, with a typical accuracy of 3.5 mm and detection of objects from Ø12 mm. The 3 mm chemically strengthened front glass is anti-reflective and resists fingerprints, with 84% typical light transmission. Windows 8.1 and Windows 10 are the listed operating systems for the touch function.
Where it fits in Qatar
- Retail and malls: a jewellery or fashion window in West Bay or Msheireb showing product information while the stock stays visible behind the glass.
- Showrooms and lobbies: a real estate sales office in Lusail or The Pearl using the touch surface to present floor plans over a model or a view.
- Hospitality: a hotel lobby in Doha using the display as a wayfinding point at the front desk, installed in an air-conditioned space.
What to plan before ordering
The rated operating temperature is 0 °C to 40 °C, with humidity between 10% and 80%. Qatar summer temperatures regularly exceed 45 °C, so the display must sit in a climate-controlled interior. Positions in direct sun or in unconditioned spaces fall outside the rated range, and the SmartRooms Qatar team will confirm the environment with you before quoting.
The head weighs 12.9 kg and the signage box 3.4 kg. The design is semi-assembled, so the wall, frame or stand plan must allow for the head and box being separated by cables. Typical power draw is 84 W with a 300 W maximum and 0.5 W standby, which helps when sizing circuits and ventilation. A free site survey lets us check fixings and cable routes before delivery.
Connectivity and software
Inputs include one HDMI, one DisplayPort, one RJ45 LAN, RS232C and IR, with DisplayPort, LAN, RS232C and IR outputs also listed. Two USB 2.0 Type A ports and an audio output are provided. Daisy Chain is listed as not supported, so each unit needs its own source. The software list includes SuperSign CMS, SuperSign Control+, Connected Care and Mobile CMS, with 16GB of internal memory and webOS 4.0.
