Abstract
The utility model provides a prevent impaired cell -phone screen module of circuit board, includes TFT LCD module and CTP capacitive touch screen, CTP capacitive touch screen be located TFT LCD module's top, and TFT LCD module and CTP capacitive touch screen realize connecting through peripheral framework, the framework in be provided with the plastic strip, the plastic strip is located the below after TFT LCD module and the CTP capacitive touch screen coincide, the one end of framework sets up opening, its characterized in that: the plastic strip upper surface that is close to the framework open end be provided with thickness and glue for 0.2 -0.6mm's OCA transparent optical. Have and can not arouse the difference in height to guarantee that the ITO conductive glass layer can not cracked advantage.
Description
Technical field
The utility model relates to mobile phone Mobile phone screen module technical field, is specifically related to a kind of Mobile phone screen module preventing circuit board impaired.
Background technology
Mobile phone screen module generally comprises TFT liquid crystal module, then needs to install CTP capacitive touch screen in TFT liquid crystal module, could realize like this touching function; TFT liquid crystal module realizes being connected with the framework of CTP capacitive touch screen by periphery, arranges plastic strip in framework and between TFT liquid crystal module and CTP capacitive touch screen, realizes fitting tightly and soft contact.CTP capacitive touch screen wherein, its structure generally comprises, lower glass plate protective seam and the ITO conductive glass layer being sandwiched in centre, and plastic strip is due to the defect of production process, and framework one end open is arranged for drawing the flexible circuit board in TFT liquid crystal module, cause the thickness of the plastic strip near framework open at one end thin compared to other position, thus cause thickness difference, and the thickness of CTP capacitive touch screen glassivation is only 0.015mm, the thickness of ITO is also only about 0.2mm, when assembling with TFT liquid crystal module, must press to make the two laminating, thus cause the ITO electro-conductive glass fault rupture in CTP capacitive touch screen, thus affect the result of use of CTP capacitive touch screen.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides one to cause difference in height, thus ensures the Mobile phone screen module preventing circuit board impaired that ITO conductive glass layer can not rupture.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of Mobile phone screen module preventing circuit board impaired, comprise TFT liquid crystal module and CTP capacitive touch screen, described CTP capacitive touch screen is positioned at the top of TFT liquid crystal module, and TFT liquid crystal module realizes being connected by the framework of periphery with CTP capacitive touch screen, plastic strip is provided with in described framework, plastic strip be positioned at TFT liquid crystal module and CTP capacitive touch screen superimposed after below, one end of framework arranges opening, it is characterized in that: described plastic strip is provided with near the upper surface of framework openend the OCA transparent optical cement that thickness is 0.2-0.6mm.
Adopt said structure, described plastic strip is provided with the OCA optical cement that thickness is 0.2-0.6mm on framework openend, compensate for the defect of plastic strip two ends difference in height, even if TFT liquid crystal module and CTP capacitive touch screen are carried out install, when pressing, also can ensure that CTP capacitive touch screen does not bend, thus available protecting ITO electro-conductive glass wherein do not fractureed, impaired, and then ensure the result of use of CTP capacitive touch screen; In addition, adopt OCA transparent optical cement to carry out padded, one can make CTP capacitive touch screen directly all realize soft contact with plastic strip and TFT liquid crystal module; And because OCA transparent optical cement transmittance is up to more than 98% and adhesive solidification ability is strong, both can not affects the display effect of full screen, can also realize fitting more closely between TFT liquid crystal module and CTP capacitive touch screen.
As preferably, the thickness of described OCA transparent optical cement is 0.3-0.5mm, more preferably 0.4mm.
As preferably, the lateral wall on the long limit of described plastic strip is provided with projection, and described framework madial wall correspondence position has been provided with draw-in groove, described projection and draw-in groove clamping, and projection obtains outside surface and draw-in groove inside surface fits; Adopt this structure, be beneficial to the elastic deformation power of plastic strip and framework, realize the connection between plastic strip and framework, this anatomical connectivity is firm, is easy to dismounting.
Accompanying drawing explanation
The Mobile phone screen modular structure schematic diagram that Fig. 1 the utility model prevents circuit board impaired.
Fig. 2 the utility model arranges plastic strip and the frame structure schematic diagram of the structure of projection and draw-in groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, but is not limited only to following examples.
As shown in accompanying drawing 1-2: a kind of Mobile phone screen module preventing circuit board impaired of the present utility model, comprise TFT liquid crystal module 1 and CTP capacitive touch screen 2, described CTP capacitive touch screen 2 is positioned at the top of TFT liquid crystal module 1, and TFT liquid crystal module realizes being connected by the framework 3 of periphery with CTP capacitive touch screen, plastic strip 4 is provided with in described framework 3, plastic strip be positioned at TFT liquid crystal module 1 and CTP capacitive touch screen 2 superimposed after below, one end of framework arranges opening, it is characterized in that: described plastic strip is provided with near the upper surface of framework 3 openend the OCA transparent optical cement 5 that thickness is 0.2-0.6mm.
Adopt said structure, described plastic strip is provided with the OCA optical cement that thickness is 0.2-0.6mm on framework openend, compensate for the defect of plastic strip two ends difference in height, even if TFT liquid crystal module and CTP capacitive touch screen are carried out install, when pressing, also can ensure that CTP capacitive touch screen does not bend, thus available protecting ITO electro-conductive glass wherein do not fractureed, impaired, and then ensure the result of use of CTP capacitive touch screen; In addition, adopt OCA transparent optical cement to carry out padded, one can make CTP capacitive touch screen directly all realize soft contact with plastic strip and TFT liquid crystal module; And because OCA transparent optical cement transmittance is up to more than 98% and adhesive solidification ability is strong, both can not affects the display effect of full screen, can also realize fitting more closely between TFT liquid crystal module and CTP capacitive touch screen.
The thickness of the OCA transparent optical cement described in this practicality is 0.3-0.5mm, more preferably 0.4mm.
The lateral wall on the long limit of the plastic strip described in this practicality is provided with projection 4.1, and described framework madial wall correspondence position has been provided with draw-in groove 3.1, described projection and draw-in groove clamping, and projection obtains outside surface and draw-in groove inside surface fits; Adopt this structure, be beneficial to the elastic deformation power of plastic strip and framework, realize the connection between plastic strip and framework, this anatomical connectivity is firm, is easy to dismounting.
This practical plastic strip 4 is in framework 3 clamping or bondd by side, and TFT liquid crystal module 1 and CTP capacitive touch screen about 2 bond in rear clamping and antibody, are positioned at plastic strip 4 top simultaneously.Of the present invention up and down, evenly position, direction shown in accompanying drawing is accurate for left and right etc.
