Embodiment
Below will combine accompanying drawing, the embodiment and the embodiment of the utility model specified, described specific embodiment in order to explain the utility model, is not the embodiment that is used to limit the utility model only.
A kind of liquid crystal display module of the utility model, its structure blast sketch is as shown in Figure 1, comprises polaroid 110, LCD screen 120, following polaroid 130, main FPC 140, LED lamp 150, components and parts 160, module backlight 170 and metal frame 180; In conjunction with shown in Figure 2; Fig. 2 is the sectional structure sketch of liquid crystal display module; Said upward polaroid 110 is attached to the front of LCD screen 120, and said polaroid 130 down is attached to the back side of LCD screen 120, and said module 170 backlight abuts in the said back side of polaroid 130 down; Be provided with the member slot 172 that is used for built-in LED lamp 150 in the lower end of said module 170 backlight; Wherein, said LED lamp 150 and components and parts 160 all are mounted on the surface of main FPC 140; And abut in LCD behind positive main FPC 140 reflexeds that electrically connect LCD screen 120 of LCD screen 120 and shield 120 back sides; Said LED lamp 150 and components and parts 160 all are positioned at the member slot 172 of said module backlight 170 lower ends; Said module backlight 170 is buckled in the metal frame 180 through the grab of periphery.
Wherein, As shown in Figure 2; Said module backlight 170 still comprises glue shell, reflectance coating, film (being LGP) and optical diaphragm group (containing bright enhancement film and scattering sheet etc.); But different is in the module backlight 170 of the utility model, no longer to comprise the backlight little FPC that is pasted with the LED lamp with module backlight of the prior art; Said LED lamp 150 directly is welded on the main FPC 140.LED lamp 150 and components and parts 160 can machine through a SMT in addition, have also avoided the welding sequence of original LCM master FPC and little FPC backlight, the thickness stack of main FPC, little FPC backlight and scolding tin more can not occur; Not only practice thrift the material cost of LCM, also practiced thrift the manufacturing cost of LCM.
In the preferred implementation of the utility model liquid crystal display module; Be preferably; Be positioned at member slot 172 setting that these module backlight 170 lower ends are used for built-in LED lamp 150 and help the groove structure of hollow out, member slot 172 has not had the bottom surface thus, can reduce the thickness of module 170 backlight; Its thickness with the main FPC 140 that is pasted with LED lamp 150 and components and parts 160 is equated, with the gross thickness of further reduction LCM.
Be preferably; Said LED lamp 150 is positioned on the surface of main FPC 140 the same sides with components and parts 160; Avoid thus on main FPC 140, producing the thickness that adds up with components and parts 160 because of said LED lamp 150; Can make full use of the space thickness of said module backlight 170 lower end hollow out member slot 172, with the gross thickness of further reduction LCM.
Be preferably; Because in the member slot 172 of said LED lamp 150 and the said module backlight of all interior plant of components and parts 160 170 lower ends; The light outlets of said LED lamp 150 or light-emitting area face the film (being LGP) in the module 170 backlight; So in order to reduce the light loss of LED lamp 150, improve the luminous utilization factor of LED lamp 150, can the lower end of the reflectance coating 171 in the said module 170 backlight be extended to the lower end of said member slot 172 always.
In addition; As shown in Figure 2; Available double faced adhesive tape is fixed on the back side of LCD screen 120 behind main FPC 140 reflexeds, and is pasted with polaroid 130 down at the back side of LCD screen 120, in order to reserve the regional space that can attach to the part behind said main FPC 140 reflexeds; The lower edge of this time polaroid 130 does not extend to the bottom that said LCD shields 120 back sides; But only extending to the top of adaptive said module 170 lower end hollow out member slot 172 backlight, the said thus space thickness of polaroid 130 bottoms down can be used for offsetting part and the thickness of double faced adhesive tape thereof behind main FPC 140 reflexeds, helps realizing the slimming design of LCM.
As shown in Figure 3; Fig. 3 is the LCD screen structure diagram in the liquid crystal display module, and said LCD screen 120 comprises CF (Color filter, colored filter) layer 123 and TFT (Thin film Transistor; Thin film transistor (TFT)) layer 121, and the lower end of CF layer 123 will be lacked than the lower end of TFT layer 121.In traditional LCD screen, all be the top layer that the CF layer is positioned at the LCD screen, the TFT layer is positioned at the bottom of LCD screen.Thickness for further attenuate LCM; Can TFT layer 121 be placed the top layer (promptly positive) of LCD screen 120; CF layer 123 is placed the bottom (being the back side) of LCD screen 120; In other words, be inverted the CF layer 123 and TFT layer 121 of LCD screen 120, just can obtain the space thickness of CF layer 123 bottom; The space thickness that the thickness that is pasted with the main FPC 140 of LED lamp 150 and components and parts 160 thus equals CF layer 123 bottom adds up and down the space thickness of polaroid 130 bottoms and adds the space thickness of member slot 172, thereby is beneficial to the slimming design of further realization LCM.
Based on above-mentioned liquid crystal display module; The utility model has also proposed a kind of ultra thin handset; Comprise shell and inner liquid crystal display module thereof, this liquid crystal display module can be set to the liquid crystal display module described in above-mentioned each embodiment, to satisfy the designing requirement of ultra thin handset.
Compare with mobile phone of the prior art and liquid crystal display module thereof; A kind of ultra thin handset that the utility model provided and liquid crystal display module thereof will the LED lamp in backlight be arranged on the main FPC that electrically connects the LCD screen because this liquid crystal display module has adopted, and with components and parts with main FPC reflexed after in the member slot of plant module backlight lower end; Not only saved traditional backlight little FPC; Merged the SMT process twice, attenuate LCM thickness, reduced the FPC materials; Reduce LCM and made and material cost, realized the lightening of LCM and mobile phone thereof.
Should be understood that; The preferred embodiment that the above is merely the utility model is not sufficient to limit the technical scheme of the utility model, concerning those of ordinary skills; Within the spirit and principle of the utility model; Can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection domain of the utility model accompanying claims.
