Abstract
The utility model discloses a liquid crystal display module set which comprises a liquid crystal display panel (2) which is horizontally arranged at the front side of a driving circuit board (1). The driving circuit board and the liquid crystal display panel are electrically connected by an electric conducting rubber strip (3) which is arranged at the end part of the liquid crystal display panel, the driving circuit board, the liquid crystal display panel and the electric conducting rubber strip are inlaid together by a framework (4), and the contacting position of the framework and the driving circuit board and the contacting position of the liquid crystal display panel and the electric conducting rubber strip have proper thickness which is sufficient for hindering an insulating coating (6) which is broken down by static electricity. After the utility model is adopted, the possible harm of the static electricity on electron devices in the liquid crystal display module set can be efficiently prevented by additionally installing the insulating coating, the static interference in normal work can be avoided and the integral service life of the liquid crystal display module set can be ensured.
Description
Technical field
The utility model relates to a kind of liquid crystal display module, relates in particular to chip for driving nation and fixes on architecture advances (chip on board), that abbreviate COB type liquid crystal display module (liquidcrystal display module, abbreviation LCM) as on the specific plate.
Background technology
The liquid crystal display module has been widely used in every field now as display device very much, wherein, COB type LCM basic structure is: the drive circuit board and the display panels (LCD) that is flat on the drive circuit board front side that have chip, both generally are electrically connected by the conductive adhesive tape that is installed in the display panels end, realize the in good time control of drive circuit board to the shows signal of display panels, described display panels generally comprises two substrates and the liquid crystal material between this substrate constitutes; During actual the use, aforementioned these parts need also that the enough frameworks of intensity are fixing securely with it, edge lumps together, and when size of display panels is big, generally need select metal framework for use, can satisfy concrete request for utilization as chase.As display device itself generally is directly in the face of the operator, because human body has static through regular meeting, the sassafras that perhaps rubs also can produce static, and its voltage generally can reach 3000 volts, sometimes even up to 15000 volts.When operation or touch display unit, because framework and drive circuit board, the conductive adhesive tape distance is very approaching, generally have only about 0.1-0.3mm, with the distance of ITO conductive pin on the display panels (LCD) generally only about 0.2mm, therefore this high-pressure electrostatic often can be transferred on the drive circuit board by the framework of conduction, disturb the operate as normal of drive circuit board, also can cause burning of electronic devices and components on the drive circuit board when serious, damage, the normal display quality and the whole service life of liquid crystal display module have been reduced, especially when selecting for use metal framework to fix each display device, this problem is more apparent outstanding.
Summary of the invention
For overcoming the defective of above-mentioned prior art, technical problem to be solved in the utility model is intended to provide a kind of liquid crystal display module that static is had better protection effect.
For solving the problems of the technologies described above, the utility model proposes a kind of liquid crystal display module, comprise the display panels that is flat on the drive circuit board front side, described drive circuit board and display panels are realized being electrically connected by the conductive adhesive tape that is installed in the display panels end, described drive circuit board, display panels and conductive adhesive tape lump together by the framework edge, are provided with the insulating coating that thickness is enough to hinder electrostatic breakdown at the internal layer of described framework and the contact site of described drive circuit board, display panels and conductive adhesive tape.
After adopting said structure, owing to have additional the insulating coating of one deck thickening especially in the contact site of framework and drive circuit board, display panels and conductive adhesive tape, therefore can prevent effectively that static may be to the infringement of the electron device in the liquid crystal display module, guarantee that the utility model avoids the whole service life of electrostatic interference and liquid crystal display module when operate as normal.
To and be elaborated to the utility model in conjunction with the accompanying drawings by embodiment below.
Description of drawings
Fig. 1 is the side structure diagrammatic cross-section of a kind of embodiment of the present utility model;
Among the figure, 1 expression drive circuit board; 2 expression LCD; 3 expression conductive adhesive tapes; 4 expression metal frameworks (as chase); 5 expression LED-backlit sources; 6 expression insulating coatings.
Embodiment
With reference to accompanying drawing 1 and Fig. 2, in a kind of implementation of the present utility model, the liquid crystal display module, comprise the display panels 2 that is flat on drive circuit board 1 front side, this drive circuit board 1 and display panels 2 are realized being electrically connected by the conductive adhesive tape 3 that is installed in the display panels end, to realize the in good time control of drive circuit board to the shows signal of display panels, generally speaking, between display panels 2 and drive circuit board 1, if necessary LED-backlit source 5 can also be set further; Display panels is made of two substrates and the liquid crystal material between this substrate usually; Described drive circuit board 1, display panels (LCD) 2 and conductive adhesive tape 3 pass through metal framework, close as chase 4 edges, be fixed together, for preventing that effectively static may be to the infringement of the electron device in the liquid crystal display module, internal layer and described drive circuit board at chase 4, the contact site of display panels and conductive adhesive tape is provided with the insulating coating 6 that thickness is enough to hinder electrostatic breakdown, these insulating coating 6 thickness generally need be between 0.06-2.0mm, promptly can satisfy requirement of shelter, insulation coating layer thickness is preferably 0.15mm, in order to make, can be further the internal layer of chase 4 all be coated with this insulating coating 6 to the Electrostatic protection better effects if.
Facts have proved, set up the insulating coating 6 of one deck thickening in the chase 4 and the contact site of the electron device that shows module after, when insulation coating layer thickness is 0.15mm, do esd immunity test (ESD), the static gun head directly contact chase discharge reach 8000 volts, when the sky discharge reaches 15000 volts, the liquid crystal display module still can have normal demonstration, effect is very good, particularly when using metal framework, the normal working performance of liquid crystal display module and whole service life can both be significantly improved.
