During the operation of the flat-panel backlight panel 1, the ion fan 311 is controlled to absorb external air and transport it to the inner cavity of the hollow bottom plate 31. The airflow takes away the heat emitted from the bottom of the flat-panel backlight panel 1, thereby realizing the function of fully dissipating heat for the flat-panel backlight panel 1. At the same time, the airflow output by the ion fan 311 carries an electric charge, which can eliminate the static electricity on the flat-panel backlight panel 1 by neutralization, and the air after heat dissipation can be output from the air outlet channel 35.

[0029] In this embodiment, an air outlet channel 35 is opened at the bottom of the hollow bottom plate 31, and an air intake duct 312 is fixedly connected to the bottom of the ion fan 311. A cooling plate 313 is fixedly installed at the bottom of the air intake duct 312. An air filter frame 314 is movably inserted at the front of the air intake duct 312. The cooling plate 313 is an existing structure, and the cold end of the cooling plate 313 is attached to the bottom of the air intake duct 312.

[0030] In this embodiment, the display screen positioning mechanism 2 includes a hollow stopper 21 and a support seat 22. The hollow stopper 21 is fixedly installed on the top of the flat-panel backlight panel 1. The outer wall of the flat-panel display screen 11 is movably connected to the outer wall of the hollow stopper 21. A through hole 211 is provided on the side of the hollow stopper 21 close to the flat-panel display screen 11. An elastic rubber plate 212 is fixedly connected to the inner wall of the through hole 211.

The air pump 25 is controlled to work and can deliver gas to the inner cavity of the hollow disk 23. Then, the continuously increased air pressure inside the hollow stopper 21 causes the elastic rubber plate 212 to produce elastic deformation and fit on the outer wall of the flat display screen 11, so that the flat display screen is fixed by friction. 11 has the function of positioning, and the solenoid valve 26 is controlled to be opened, so that the gas inside the hollow limiter 21 can be released, and the positioning of the flat-panel display screen 11 can be released, which is convenient for the operator to use. The digital barometer 24 and the air pump 25 are both existing structures, and are both connected to the external controller by electrical signals. The digital barometer 24 can monitor the air pressure inside the hollow disk 23. During the operation of the air pump 25, after the air pressure reaches the preset value, the external controller can control the air pump 25 to be closed in time, so as to avoid the problem that the flat-panel display screen 11 is easily damaged due to high air pressure.

[0031] The working principle of a backlight plate for a flat panel display screen of the utility model is as follows: when testing the flat panel display screen 11, the flat panel display screen 11 is attached to the top of the flat panel backlight plate 1, and the air pump 25 is controlled to work to deliver gas into the hollow disk 23. The continuously increased air pressure inside the hollow limiter 21 causes the elastic rubber plate 212 to produce elastic deformation and attach to the outer wall of the flat panel display screen 11, so as to achieve the positioning of the flat panel display screen 11, and then the testing work can be carried out. During the testing process, the ion fan 311 is controlled to work to provide heat dissipation protection for the flat panel backlight plate 1.
