The invention relates to the technical field of display screens, in particular to a display screen with an AG anti-dazzle effect and a using method thereof.The display screen comprises a shell, a heat dissipation device, a supporting device and a storage device, a display body is fixedly connected into the shell, an AG anti-dazzle glass plate is fixedly connected to the front of the display body, a fixing shell is fixedly connected to the rear of the shell, and the AG anti-dazzle glass plate is fixedly connected to the back of the fixing shell. The heat dissipation device comprises a shell, a fixing frame, a dustproof plate, an electric fan, an air inlet shell, a connecting shell, a heat conduction pipe, a connecting pipe and heat conduction fins, a control main body is arranged in the fixing shell, the right front of the control main body is fixedly connected with the shell, a heat dissipation device is fixedly connected in the fixing shell, and storage devices are fixedly connected to the two sides of the rear portion of the shell. The heat generated by the control main body can be conveniently conducted out, the heat generated by the display main body and the control main body is reduced, the aging speed of the display main body and the control device is reduced, and the display screen is more stable in use.
