# TCOMAS LG600: reconstructing a cooler LCD's USB HID display protocol

> TCOMAS LG600 reconstructs the USB HID image-transfer protocol of a 480×480 cooler LCD from vendor-app traffic. Its Python package encodes images as JPEG, splits each frame into HID output reports, and streams them to the display. The documented report format and timing constraints are based on one tested LG600 unit.
