Abstract
The utility module provides a liquid crystal display module (LCM). The LCM comprises a rubber frame, a liquid crystal and a backlight combination module contained in the rubber frame, a soft circuit board electrically connected with the backlight combination module, and a rear panel arranged on the rubber frame. The soft circuit board is arranged between the liquid crystal and the backlight combination module and the rear panel which includes a base board and side boards which are arranged on two opposite sides of the base board. The side boards are connected with the rubber frame in a matching mode. One side board is provided with a channel. The base board of the rear panel is covered on the soft circuit board which extends out of the channel of the side board to achieve external circuit connections. The whole intensity of the LCM is improved, and capacity of resisting disturbance of the LCM is strengthened. Due to the fact that most part of the soft circuit board is within the coverage area of the rear panel, only a portion formed by the soft circuit board extending out of the rear panel needs to be coated with protecting glue, and therefore production cost is reduced, level property of the LCM is guaranteed, and thinning of the LCM is benefited.

Another purpose of the utility model is to provide a kind of LCM to show module, and it coats liquid crystal and combination module backlight fully through backboard, improves the structural strength that LCM shows module, promotes anti-dropping capability.
For realizing above-mentioned purpose; The utility model provides a kind of LCM to show module; Comprise: the glue frame, be contained in the FPC of liquid crystal and combination module backlight, electric connection liquid crystal and combination module backlight in this glue frame and be installed on the backboard on the glue frame, said flexible circuit board is between liquid crystal and combination module backlight and backboard, and said backboard comprises base plate and is located at the side plate of these relative both sides of base plate; Said side plate and glue frame are connected; Said side plate is provided with a passage, and the base plate cover of said backboard is on flexible circuit board, and flexible circuit board stretches out externally to carry out circuit from the passage of side plate and connects.
Said glue frame is provided with several installation portions, and corresponding those installation portions of the side plate of said backboard are provided with corresponding mounting hole, and those installation portions are sticked in those mounting holes.
The base plate of said backboard covers liquid crystal and combination module backlight fully.
The thickness of said flexible circuit board is 0.13mm.
Said liquid crystal and combination module backlight comprise a LGP, and its thickness is 0.4mm.
The beneficial effect of the utility model: the LCM that the utility model provides shows module; Cover the whole LCM of support by backboard and show module, improved the bulk strength of LCM demonstration module, strengthened the antijamming capability of LCM demonstration module; Improve and produce yield; And, only need to extend the part coating protection glue outside the backboard, and then reduced production cost at FPC because the major part of FPC is within the coverage of backboard; Guaranteed that simultaneously LCM shows the planarization of module, helps the slimming that LCM shows module.
In order further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through embodiment the utility model, the technical scheme that makes the utility model and other beneficial effect is obvious.
In the accompanying drawing,
Fig. 1 shows the three-dimensional exploded view of module for the utility model LCM;
Fig. 2 shows the structural drawing of module for the utility model LCM.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with the preferred embodiment and the accompanying drawing thereof of the utility model.
See also Fig. 1 to 2; The utility model provides a kind of LCM to show module, comprises backboard 1, glue frame 2, liquid crystal and combination module 3 backlight and FPC 4, and this liquid crystal and combination module 3 backlight are contained in the said glue frame 2; This backboard 1 is installed on the said glue frame 2; This FPC 4 is electrically connected at this liquid crystal and combination module 3 backlight, and is arranged between this liquid crystal and combination module 3 backlight and the backboard 1, covers the shielding that most flexible circuit boards 4 is realized flexible circuit board 4 through backboard 1; Reduce being coated with electrostatic defending glue amount, reduce production costs.
Said backboard 1 comprises base plate 11 and is located at the side plate 12 of these base plate 11 relative both sides; Said side plate 12 is connected with glue frame 2; Said side plate 12 is provided with a passage 122; The base plate 11 of said backboard 1 covers on flexible circuit board 4, and then has guaranteed the planarization of flexible circuit board 4, has also improved the antijamming capability of this LCM demonstration module simultaneously to a great extent.
Said glue frame 2 is provided with several protruding installation portions 21; Side plate 12 corresponding those installation portions 21 of said backboard 1 are provided with corresponding mounting hole 121; Those installation portions 21 are sticked in those mounting holes interior 121; Thereby with liquid crystal and combination module backlight 3 whole being fixedly installed in the backboard 1, the base plate 11 of backboard 1 covers liquid crystal and combination module 3 backlight fully, has further improved LCM and has shown intensity, the whole degree of module and produce yield.
