Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at (859) 342-6060 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Precise Touch Response

The screen accurately recognizes even the smallest touch points and instantly shows a response. This level of accuracy means that SIs can compose GUI icons in a variety of sizes on the 55TC3CD and users can fully enjoy their touch experience with no lagging.

Multi Touch with No Dead Zones

Capable of recognizing up to 40 point-touches at once, the screen provides users with a more realistic sense of touch. Unlike IR touch screens, the display accurately detects touch points even at the corners or edges of the display. This allows a variety of touch-based customer services to be provided throughout the entire screen.

True Color, Wide View

LG IPS panel features a wide viewing angle to deliver clear content regardless of where meeting participants are seated. Each pixel in the IPS panel reproduces image colors true-to-life, without distortion.

Vivid Color Details with Ultra HD

The UHD resolution allows users to view details even when zooming in on the display, with four times higher definition than FHD. The 55TC3CD ensures stable UHD video playback with HEVC (High Efficiency Video Coding).

Fewer Scratch & Shatter Proof

When a user touches a screen directly, this can result in scratches on the screen or even damage to the glass. The 55TC3CD has an advanced tempered screen coating to minimize scratches. In addition, its anti-shatter glass is designed to minimize harm to the user, even in the event of an external shock.

Conformal Coating

The product can be often unavoidably exposed to dust and water during maintenance. Conformal coating on power board eliminates such circumstances by protecting it against dust, iron powder, humidity, etc.

Embedded Group Manager

The embedded CMS* allows you to edit and play content, schedule a playlist and even group and control signages via remote control, without need for a separate PC. This makes content management much easier and user-friendly.

Multi Screen Mode

PBP (Picture-By-Picture) and PIP (Picture-In-Picture) enables up to two divided split screens in landscape or portrait display format enabling users to more flexibly allocate space for each content source.

Various Sensor Applications

LG webOS smart signage platform easily supports connections with external sensors such as GPIO, NFC/RFID, temperature sensors, etc. via USB plug-in. The overall cost of ownership is reduced as there's no need to purchase additional software or media players.

OPS Player Connectivity

The 55TC3CD provides an OPS (Open Pluggable Specification) Kit to connect a third-party OPS player. Users have the flexibility to choose any media player as long as it complies with the OPS.
