Description

High-contrast large-screen liquid crystal display panel structure Technical Field The utility model relates to the technical field of display panels, in particular to a high-contrast large-screen liquid crystal display panel structure. Background The liquid crystal panel is a core component of a Liquid Crystal Display (LCD), and is widely applied to the fields of televisions, computer monitors, mobile phones, tablet personal computers, vehicle-mounted display screens and the like. The liquid crystal display device realizes image display by controlling the arrangement state of liquid crystal molecules, and has the advantages of light weight, low power consumption, relatively low cost and the like. The large-screen liquid crystal display panel is widely applied to high-environment requirement scenes such as command control, digital signage and industrial monitoring, but the prior art faces a core bottleneck: Interface reliability defect The high dust environment of industrial scenes (e.g. mines, worksites) leads to a significant increase in interface failure rate: particle invasion damage that dust enters into the interface of HDMI/USB interface, resulting in the increase of data transmission error rate. Disclosure of utility model The object of the present utility model is to solve at least one of the technical drawbacks. Therefore, an objective of the present utility model is to provide a high-contrast large-screen liquid crystal display panel structure to solve the problems mentioned in the background art and overcome the shortcomings of the prior art. In order to achieve the above object, an embodiment of an aspect of the present utility model provides a high-contrast large-screen liquid crystal display panel structure, including a frame, a display panel, and a back machine, wherein the display panel is fixedly connected to an inner side of the frame, and the back machine is detachably connected to a rear side of the frame; a plurality of heat dissipation grooves are formed in the edge of the back machine, and a notch is formed in the lower portion of the back machine; The inner side of the notch is fixedly connected with a plurality of connectors, and the opening of the notch is detachably connected with a cover body; the cover body is provided with a plurality of reserved openings, and the reserved openings are in one-to-one correspondence with the interfaces; A cover is detachably connected to the reserved opening, and a notch is formed in the cover; the surface of the flap is fixedly connected with a circle of elastic buckles, and the elastic buckles can be clamped at the inner side of the reserved opening; the other side of the opening cover is fixedly connected with a handle. In any of the above aspects, preferably, the frame is made of an aluminum alloy, and the frame and the back machine are fastened by a multi-point screw.
