[Prior Art] The thinning of electronic devices is the trend of the times, and the support functions are numerous. Therefore, electromagnetic interference (EMI) and Electrostatic Interference (ESD) are increasing. Generally speaking, electromagnetic Interference and electrostatic discharge problems occur mostly in the vicinity of the integrated circuit of the electronic device. The conventional method is to cover the copper foil or the housing of the electronic device itself to avoid electromagnetic interference from the outside of the housing or interaction with other parts. Electromagnetic interference, and the copper foil can be grounded to the electronic device housing to increase the anti-static discharge capability. However, the above-mentioned conventional methods still have the following disadvantages: 1. The copper foil attaching is time-consuming and labor-intensive. 2. When the copper foil is combined with the integrated circuit, the attached force should not be too large. Otherwise, the integrated circuit is easily damaged without being known. 3. If it is necessary to shield the integrated circuit and the circuit board electrically connected to the integrated circuit at the same time, it is easy to cause a gap because the copper foil covering area is too large, thereby reducing the electromagnetic interference or the electrostatic discharge dissipation effect. 4 1344338 Fourth, due to the inevitable existence of the distance between the electronic device housing and the integrated circuit, when the electromagnetic interference of the integrated circuit is dissipated, it will continuously circulate inside the electronic device housing, and the electromagnetic interference cannot be dissipated.

When the shielding member 9 is pushed When the protrusion 921D enters the groove 553 and slides to the second positioning hole 552, as shown in FIG. 12, the body 91D of the shield 90D can cover the bend 721 of the flexible printed circuit board 72, facing The connecting piece 93D of the liquid crystal panel 70 can cover the integrated circuit 71 of the 1344338 liquid crystal panel 70, and the other connecting piece 93D can be pressed onto the flexible printed circuit board attached to the backlight module (not shown in the drawing, refer to The situation shown in the nine figures). In summary, the display device provided by the present invention is provided with a movable shielding member having functions such as EMI (Electr〇 Magnetic Interference) and Electrostatic Discharge (ESD), which can suppress the display device. Reflexed flexible printed circuit board, avoiding the soft printed circuit board to retort, according to the actual sample verification, through the shielding device of the present invention, can effectively reduce the electromagnetic interference of about 2DBm, and the electrostatic discharge can be reduced by 4. 5KV is increased to 8KV (about 80% ESD tolerance). However, the above description is only an embodiment of the present invention, and the scope of the present invention is not limited thereto. That is to say, the equivalent changes and modifications made by the applicant in accordance with the scope of application of the present invention should still fall within the scope covered by the patent of the present invention. I would like to ask you to review the examinations and pray for the best.
