Abstract
The utility model relates to the field of liquid crystal displays, in particular to a rear panel for a liquid crystal display convenient to radiate. The rear panel for the liquid crystal display convenient to radiate comprises a rear panel main body which is made of aluminum, a semiconductor refrigeration module is arranged at the back of the rear panel main body, and the semiconductor refrigeration module is connected with a direct-current power supply which is used for supplying power. An original rear panel into the aluminum rear panel, and refrigeration can be achieved through the semiconductor peltier effect of the semiconductor refrigeration module. After the rear panel is improved, 80% of heat (high temperature) generated by operation of a lamp tube / a lamp strip can be radiated, and radiation effect of the rear panel main body can be effectively improved.
