Description

The big screen display screen unit

Technical field the utility model relates to electronic display unit, particularly the display screen unit of giant-screen.

Background technology is the display unit on big screen display screen at present, all is to use metal shell.The display unit of this structure is heavier, erecting frame is required high, and housing itself can not electrostatic prevention, thunderbolt and corrosion.Because housing is shaped or welding forming by metallic plate punching,, make troubles or distortion or the like in use to assembly working so precision is not high.In addition, during this display unit, each displaying block is separately fixed on the panel of housing one side, take a lot of work, time-consuming in assembling, simultaneously need be in housing repeatable operation, also increased the difficulty of assembling.

The summary of the invention the purpose of this utility model is for fear of above-mentioned the deficiencies in the prior art, for the user provide a kind of in light weight, protection effect good, easy to assembly and big screen display screen unit that cost is low.

The utility model comes specific implementation by implementing following technical scheme, the big screen display screen unit that this programme is designed, comprise housing, the display board that contains displaying block and substrate is fixed on the one side of housing by substrate, and the drive controlling plate is fixed on the another side of housing.Described housing is the frame body of being made by plastic material, and described substrate is holistic panel, and can embed in the space at housing middle part, between described displaying block and the housing sealant is arranged.This programme is a plastic material with case design, can electrostatic prevention, thunderbolt and corrosion, alleviate the weight of this display unit.And because by injection molded, so the precision height, it is easy and durable in use to assemble.With case design is framed structure, display board can be embedded in the housing, effectively protects display element, and has reduced the thickness of display unit., earlier displaying block is fixed on the substrate of an integral body, and then this substrate is fixed in the housing during this display unit in assembling, like this can simplified assembling process, quality is convenient to control and is made things convenient for the workman to operate.Sealant can prevent that sealing or other impurity enter in the housing, guarantees the safety of internal electric parts.

Because the utility model is implemented technique scheme, so, have in light weight, protection effect good, easy to assembly and characteristics that cost is low.
