A CAMERA USED TO EXAMINE THE THERMAL SHOCK OF THE DISPLAY PANEL DEVICE MAINTAINS CONSTANT TEMPERATURE AND AUTOMATIC CONTROL METHODS

摘要

PURPOSE: A temperature keeping system of a heat-absorbing camera for testing a display panel, and a method of controlling the same are provided to prevent the camera from being affected by the temperature changes of a testing room by including a case type camera part. CONSTITUTION: A case-typed constant temperature control unit(100) is arranged outside of a testing room for heating or cooling water. A camera unit(200) is connected to the constant temperature control unit through a pipe. A camera is arranged in the testing room. A temperature control unit for the constant temperature of water is arranged in the part of the constant temperature control unit. The camera unit comprises a radiator unit for the water circulation, and a camera temperature sensor(230) for measuring the temperature of the testing room.
