Description

The LCD module

[technical field]

The invention relates to a kind of flat-panel screens module, particularly a kind of LCD module.

[background technology]

The LCD module is a kind of with assembled all-in-one-piece liquid crystal indicators such as display panels, modules backlight, its have low-voltage, little power consumption, the capacity of display big, be easy to colorize and advantage that can be portable, and be widely used in modernized information equipments such as notebook, monitor, mobile phone, personal digital assistant.

A kind of prior art liquid crystal indicator can be consulted the TaiWan, China patent the 530th of bulletin on May 1st, 2003, No. 182, as shown in Figure 1, this liquid crystal indicator 1 comprises a display panels 11, one module 12 backlight, a mold frame 13, a base 14, a procapsid 15 and a back casing 16.

This module 12 backlight comprises a light guide plate 121, is arranged on the light source 122 of these light guide plate 121 1 sides, is arranged on the reflecting plate of locating light guide plate 121 bottom surfaces 123, a plurality of optical sheets 124 that are arranged on these light guide plate 121 exiting surface places.This light source 122 is combinations of a linear fluorescent tube and a reflection lampshade, and these a plurality of optical sheets 124 are stacked from the bottom to top successively following diffuser plate, prism plate and last diffuser plates.

This display panels 11 is arranged on this optical sheet 124 upsides.This mold frame 13 is taken in this module 12 backlight and this display panels 11.This base 14 covers this mold frame 13 and assembles thereon.This procapsid 15 and back casing 16 are one with assembled such as above-mentioned base 14, display panels 11, module backlight 12 and mold frames 13, form liquid crystal indicator 1.

But, there is following problem in this liquid crystal indicator 1: because the effect of this procapsid 15 and back casing 16 only is to be one with assembled such as base 14, display panels 11, module backlight 12 and mold frames 13, it there is no other additional function, and on mechanism design, take sizable space, cause the thickness of liquid crystal indicator 1 and weight to increase easily; In addition, because procapsid 15, base 14, mold frame 13 and 16 4 frame clsss assemblies of back casing have been adopted in the assembling of this liquid crystal indicator 1, cause the too much and complex structure of this liquid crystal indicator 1 part, and increase production cost.

[summary of the invention]

For overcoming prior art LCD modular structure complicated problems, the invention provides a kind of LCD module simple in structure.

The technical scheme that technical solution problem of the present invention is adopted is: a kind of LCD module is provided, it comprises a shell, one display panels, one module backlight, an one module housing backlight and a fixed head, wherein, the a plurality of threaded holes of this shell tool, this module backlight is positioned at this display panels bottom side, this module housing backlight is accommodated this module backlight, this fixed head is tabular and corresponding with a plurality of threaded holes of this shell a plurality of through holes is set, these a plurality of screws cooperate this fixed head fixing with this shell, form and accommodate this display panels, the space of module backlight and module housing backlight.

Compared to prior art, because LCD module of the present invention adopts a shell to cooperate a fixed head to form the space of accommodating with fixing display panels, module backlight and module housing backlight, wherein this shell has the procapsid of prior art LCD module and the function of base concurrently, thereby it is comparatively simple on mechanism design, can reduce mechanism element, and reduce the cost of LCD module.

Fig. 2 is the three-dimensional exploded view of LCD module of the present invention.

Fig. 3 is the three-dimensional assembly diagram of LCD module of the present invention.

Fig. 4 is the sectional view of LCD module of the present invention along the IV-IV direction of Fig. 3.

[embodiment]

Seeing also Fig. 2, is the perspective exploded view of LCD module of the present invention.This LCD module 2 comprises a shell 21, a display panels 22, one module 23, one module housing 24 backlight backlight, a fixed head 25, a strengthening glass sheets 26 and a tablet 27.

This shell 21 comprises an opening 211 and a receiving space 212, and this opening 211 is corresponding with the size and dimension of this strengthening glass sheets 26, and these shell 21 bottom margins are provided with a plurality of threaded holes (figure does not show).This display panels 22 is in order to show image, and the receiving space 212 of its size and this shell 21 is complementary.

These module 23 usefulness backlight think that this display panels 22 provides an even brightness area source, it comprises a light guide plate 231, lays respectively at the fluorescent tube 232 and reflex housing 233 of these light guide plate 231 both sides, these light guide plate 231 upsides set gradually diffuser plate 237 on diffuser plate 235, the prism plate 236 and, and these light guide plate 231 downsides are provided with a reflecting plate 234.This fluorescent tube 232 is the cold cathode fluorescent lamp pipe, it cooperates formation one linear light source with this reflex housing 233, this linear light source is converted to area source through light guide plate 231,234 of this reflecting plates are overflowed from light guide plate 231 downsides in order to prevent light, the area source that this time diffuser plate 235, prism plate 236 and last diffuser plate 237 penetrate light guide plate 231 is more even, and can improve brightness.

This tablet 27 produces electronic signal in order to induced field, realizes the handwriting identification function of this LCD module 2.This fixed head 25 is tabulars and corresponding with a plurality of threaded holes of above-mentioned shell 21 bottoms a plurality of through holes 251 is set.

, be respectively the assembly drawing of LCD module 2 of the present invention and the sectional view after the assembling please together with reference to Fig. 3 and Fig. 4.During assembling, this reflecting plate 234, tablet 27 are successively set on this light guide plate 231 downsides, this time diffuser plate 235, prism plate 236 and last diffuser plate 237 are successively set on this light guide plate 231 upsides, this fluorescent tube 232 and reflex housing 233 are provided with the dual-side of this light guide plate 231, in the receiving space 241 of this module housing 24 backlight should module 23 backlight be contained in, this display panels 22 is positioned at this module 23 upsides backlight, and the receiving space 212 of this shell 21 is accommodated this display panels 22, module backlight 23 and module housing 24 backlight in interior.This strengthening glass sheets 26 is assemblied in opening 211 places of this shell 21.This fixed head 25 is fixed by a plurality of screws 252 with this shell 21, and this screw 252 cooperates with a plurality of threaded holes of these shell 21 bottoms by through hole 251 backs of fixed head 25, thereby this fixed head 25 is fixing with this shell 21.
