1) The document introduces Solufarm's transparent LED film display (TLM), a new type of transparent media facade. The TLM uses a very light and thin LED film that can be directly attached to windows and curved surfaces for interior or exterior use. 2) The TLM has advantages over glass LED displays such as being lighter, more flexible for installation, and lower cost. It is well-suited for uses like building facades, media art, and advertisements. 3) Solufarm has been supplying digital signage solutions including the TLM since 2006. They have over 40 customers in Korea and export to 10 countries. The TLM has received 3 patents.

A new type of media facade that plays PC-driven images on a transparent LED film using HDMI. Video
data is transmitted in RS-422 format through the HDMI Main Controller. The transmitted data is
transmitted to the LED driver through the receiver (Rx). In the transparent LED film, the power of 12V is
transmitted to the SMPS to the driver board. The driver board is connected to the FPCB of the TLM (film),
and the contents (video/text/image) displayed on the screen of the PC are displayed.
