A portable LCD screen backlight detection device

Abstract

This utility model discloses a portable LCD screen backlight testing device, including a testing instrument. The testing instrument includes a testing main unit and testing probes connected to the testing main unit via wires. A cable reel is bolted to the bottom of the testing main unit. The cable reel has symmetrical slots on its left and right sides for storing the testing probes. The front of the cable reel has an inlet hole and an outlet hole. A cable winding assembly is provided inside the cable reel. The wire enters the cable reel through the inlet hole, is wound by the cable winding assembly, and extends out through the outlet hole. The cable winding assembly is used to control the extension length of the wire. This utility model features an integrated design of the cable reel and the testing instrument. The slots securely hold the testing probes, providing fixation, protection, and convenient storage and retrieval. The cable winding assembly automatically winds up the testing instrument's cable, eliminating the need for cable ties and solving the problems of tangled wires and cumbersome storage associated with traditional equipment, significantly saving storage time.
