2results about How to "Prevent electrostatic breakdown" patented technology

This invention discloses a display module and a display device, belonging to the field of display technology. The display module includes a display panel, a flexible circuit board, and a printed circuit board. The display panel includes a bonding area, and the flexible circuit board and the printed circuit board are bonded and electrically connected to the display panel in the bonding area. The flexible circuit board and the printed circuit board are connected via a connector. The connector includes a first connecting plate and a second connecting plate. The side of the first connecting plate facing the second connecting plate includes a groove, and the groove includes a plurality of first pins. The side of the second connecting plate facing the first connecting plate includes a plurality of second pins. The first pins and second pins correspond one-to-one, and the second pins are inserted into the groove, making contact and electrical connection with the first pins. A portion of at least one first pin is coated with a first insulating layer. The display device includes the above-described display module. This invention can avoid electrostatic discharge damage to the panel during hot-plugging of the connector, which is beneficial for protecting equipment and improving product yield.

This invention provides a pin cutting device for testing integrated circuit boards, relating to the field of integrated circuit boards. The device includes a contact sleeve, an extension tube threaded onto the surface of the contact sleeve, a guide ring fixedly connected to the upper end of the extension tube, a broken track ring fixedly connected to the upper end of the guide ring, a rotating ring rotatably connected to the outer side of the broken track ring, a force plate slidably connected to the inner groove of the broken track ring, a limit block fixedly connected to the end of the force plate furthest from each other, the limit block slidably connected to the broken track ring, and a compression spring fixedly connected to the side of the limit block furthest from each other. This pin cutting device for testing integrated circuit boards prevents electrostatic discharge (ESD) from damaging the circuit board by directly contacting the circuit board with the contact sleeve, and controls the pin length through the extension tube, ensuring uniform pin lengths on the circuit board, thus preventing ESD from the contact and solving the problems of inconsistent pin lengths and ESD damage to the integrated circuit board during cutting.
