Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
the English abbreviation and corresponding Chinese translation used in the present invention are as follows:
LCD is short for Liquid Crystal Display, Chinese means: liquid crystal displays, herein referred to as liquid crystal panels.
IC is the abbreviation of Integrated Circuit, Chinese means: an integrated circuit.
FPC is the abbreviation of Flexible Printed Circuit, and Chinese means: a flexible printed circuit.
The OCA is short for optical Clear additive, and the Chinese finger: an optically clear adhesive.
OCR is the abbreviation of Optical Clear Resin, Chinese means: an optically transparent resin.
Fig. 1 shows a conventional display module structure with a cover plate, which includes a cover plate 1, wherein an ink layer 2 is printed on a lower surface of the cover plate, and the ink layer is used for decoration and shielding a non-display area of an LCD panel. The cover plate is attached to the upper surface of the LCD panel (the upper surface of the upper polarizer attached to the uppermost layer of the LCD panel) through the optical cement 3, the LCD panel comprises an upper polarizer 4, an upper glass substrate 5, a lower glass substrate 6 and a lower polarizer 7, the lower glass substrate is larger than the upper glass substrate, the upper surface of the part of the lower glass substrate, which is larger than the upper glass substrate, is integrated with a drive IC 9, and the drive IC is bound by adopting COG. A backlight 8 is integrated below the LCD panel. The liquid crystal display module is additionally provided with the cover plate attaching process, so that the cost of the liquid crystal display module without the cover plate is much higher than that of the material, and the liquid crystal display module has no competitive advantage.
As shown in fig. 2, the liquid crystal display module with the cover plate of the present invention is different from the existing display module with the cover plate, the display module of the present invention uses the upper polarizer to realize the decoration and protection functions, thereby omitting the process of attaching the cover plate again, saving the materials such as the cover plate and the adhesive, greatly reducing the cost of the display module, and having obvious market competition advantages.
Example 1
As shown in fig. 2, the liquid crystal display module of the present embodiment includes a backlight module 18 and an LCD panel, the LCD panel includes an upper polarizer 12, a lower polarizer 17, and a liquid crystal cell disposed between the upper polarizer and the lower polarizer, and the upper polarizer 12 replaces a cover plate to realize decoration and protection of the cover plate.
The liquid crystal cell described in this embodiment includes at least an upper glass substrate, a lower glass substrate, and a liquid crystal disposed between the upper glass substrate and the lower glass substrate. When going up the polaroid like this and using and the liquid crystal box is laminated, what actually laminated is the last glass substrate of liquid crystal box, go up glass substrate for being greater than down glass substrate's large glass, the last polaroid size of this embodiment is greater than and is greater than the LCD panel size promptly, just so can increase the laminating area of polaroid and liquid crystal box, and then reduce the unsettled no support region area of polaroid edge all around when going up the polaroid as the apron uses, receive the support of last glass substrate below going up the polaroid, go up the glass substrate cooperation and go up the rigidity and the hardness that the polaroid has increased last polaroid, the last polaroid disappearance deformation of equipment with the use is guaranteed, can use as the apron with reassurance.
Because the size of the upper glass substrate is larger than that of the lower glass substrate, the drive IC is bound on the lower surface of the upper glass substrate, and the FPC is bound on the lower surface of the upper glass substrate and bound through the anisotropic conductive adhesive.
Of course, the liquid crystal cell described in this embodiment is not very different from the liquid crystal cell in the prior art, and is basically the same as the liquid crystal cell in the prior art except for the above differences, and therefore, the detailed form and structure of the liquid crystal cell may be selected by the skilled person according to actual requirements as long as the above technical requirements are met.
For this embodiment, since the upper polarizer is used as the cover plate, the problem of shielding in the decoration and non-display areas is also considered, and therefore, the silk-screen printing of the decoration ink layer on the lower surface of the upper polarizer described in this embodiment is located at the outer edge of the lower surface of the upper polarizer, and the whole ink layer is in a shape of a rectangular frame, mainly plays a decoration role, and is also used for shielding non-display area structures such as wiring, a glue frame and the like of the LCD panel. The thickness of the ink layer, the ink material, the pattern and the like can be selected according to the actual product.
Go up the polaroid and use as the apron, structural problem has been solved, but still face the surface hardness not enough, the easy problem of fish tail of wear-resisting, consequently the embodiment go up polaroid upper surface chemistry coating sclerosis layer to realize the guard action of apron. The upper surface of the upper polaroid is coated with the hardened layer, so that the surface hardness and the friction resistance can be improved, and meanwhile, the liquid crystal display glass substrate below can be prevented from or directly impacted by buffering external force, and the protection function of the cover plate is achieved.
For the present embodiment, in order to secure the protective effect of the hardened layer, the hardened layer thickness is 800nm or less. The hardness of the hardened layer is 3H, the haze is less than or equal to 1%, and the hardness is pencil hardness.
Example 2
The present embodiment is different from embodiment 1 in that: the sclerosis layer adopt anti-dazzle anti-reflection sclerosis layer, the upper surface of last polaroid is made with the mode of coating to the sclerosis layer, go up the polaroid and pass through the optical cement and laminate at last glass substrate upper surface entirely. The full-laminating mode is adopted, the lower surface of the upper polaroid and the upper surface of the upper glass substrate can be completely laminated, the upper glass substrate can support the upper polaroid, the rigidity and hardness of the upper polaroid are guaranteed, the upper polaroid is guaranteed not to deform, and the upper polaroid can be used as a cover plate safely. To this embodiment, the optical cement is OCA optical cement or OCR optical cement, can guarantee the effect of laminating, also can guarantee the effect that shows.
