The invention provides an anti-electromagnetic interference low-temperature-resistant liquid crystal display screen, and belongs to the technical field of display screens. The anti-electromagnetic interference low-temperature-resistant liquid crystal display screen comprises a TP screen, a screen frame is arranged above the TP screen, the lower end of the screen frame is fixedly connected with a TP screen interface base, adhesive glue is arranged below the TP screen interface base, a TP screen interface is integrally arranged above the TP screen interface base, and the lower end of the TP screen interface is electrically connected with a TP screen signal line. A TP screen reinforcing steel sheet is connected to the lower end of the TP screen signal line, a TP screen set is arranged in the screen frame, an LCM screen is connected to the lower surface of the TP screen in a glued mode, and an LCM screen set is arranged in the LCM screen. According to the invention, a low-temperature polycrystalline silicon glass layer is added in the LCM screen, so that the low-temperature resistance of the display screen is enhanced; two electromagnetic films are designed and added to the outer side of the anti-electromagnetic wire extending out of the LCM screen, and the reinforcing steel sheet is added to the joint in a matched mode, so that the connection stability of a connector is enhanced, and the anti-electromagnetic performance is improved.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to a low-temperature resistant liquid crystal display screen that resists electromagnetic interference. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. According to the pre-programmed program to drive various connecting devices, it can be used to replace the mechanical button panel, and to produce vivid audio-visual effects through the liquid crystal display screen. As a new computer input device, the touch screen is simple, convenient and natural. A way of human-computer interaction. It endows multimedia with a new look and is an attractive new multimedia interactive device, mainly used in public information inquiry, industrial control, military command, electronic games, multimedia teaching, etc. Today's display screens have the follow...
