Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to shown in Fig. 3, Fig. 4, one of the present invention narrow screen Rimless LCDs, comprise framework 10, display panels 20, screen body 30 and back light system 40.
Refer to shown in Fig. 7, Fig. 8, described framework 10 comprises glue frame 11 and chase 12, in the present embodiment, described glue frame 11 passes through integrated injection molding with chase 12, relative to the way that conventional art gluing frame 11 is separated with chase 12, adopt integrated injection molding, the reliability of back light system 40 can be increased.The left and right lateral margin height of described chase 12 is lower than the left and right lateral margin height of glue frame 11, described display panels 20 is fixed on glue frame 11, chase 12 so can be avoided directly to contact with display panels 20 thus cause display panels 20 to be occurred by the situation scratched, the difference in height formed between described chase about 12 lateral margin and glue frame about 11 lateral margin is X3 (as shown in Figure 8), specifically, the span of X3 is: 0.15mm < X3 < 0.4mm.
Please refer to described in Fig. 4, described framework 10 has a cavity 13.Described display panels 20 to be arranged at above framework 10 and to cover cavity 13.The width of described display panels 20 is greater than the width of cavity 13, thus instead of on conventional art display panels 20 is arranged at the way in the cavity 13 of framework 10, thus effectively can increase the screen accounting of display panels 20, and decrease the thickness of framework 10, thus minimizing raw material dosage, save material, reduce production cost.Specifically, please refer to shown in Fig. 1, described screen body 30 is arranged at above display panels 20, can play the effect of protection display panels 20.As shown in Figure 2, the left and right lateral margin of described display panels 20 to screen body 30 left and right lateral margin between form fit-up gap X1, X1 is 0.1 ~ 0.14mm, so, the width that the width of described screen body 30 equals display panels 20 adds the fit-up gap of twice, thus greatly increase screen accounting, reduce the black surround region of LCDs.
Please refer to shown in Fig. 4, described back light system 40 is arranged in cavity 13.Specifically, described back light system 40 comprises the reflector plate 41, light guide plate 42, diffusion sheet 43, lower brightening piece 44 and the upper brightening piece 45 that stack successively from lower to upper.Gap between described reflector plate 41 to framework 10 medial margin is 0.1 ~ 0.15mm, described light guide plate 42 to framework 10 medial margin between gap be 0.05 ~ 0.1mm.Preferably, as shown in Figure 1, described back light system 40 also comprises first circuit board 46, second circuit board 47 and LED (not shown), and described first circuit board 46 is electrically connected with display panels 20, and described second circuit board 47 is electrically connected with LED.
Preferably, please refer to shown in Fig. 4, between described display panels 20 and framework 10, being provided with the shading glue 50 for display panels 20 and framework 10 being connected and fixed.Described shading glue 50 turn improves optical effect while meeting narrow screen.Please refer to shown in Fig. 5, Fig. 6, the lateral border of described shading glue 50 to screen body 30 lateral border between form fit-up gap X2, X2 is 0.05 ~ 0.1mm.Described display panels 20 has viewing area 21, the medial margin of described shading glue 50 to display panels 20 viewing area 21 between distance be X4, X4 is greater than 0.35mm, so can ensure that the area of the viewing area 21 of display panels 20 is less than the area in backlight luminescence district, the area because of the viewing area 21 of display panels 20 is avoided to be greater than the area in backlight luminescence district, thus cause display panels 20 to have obvious dark space when showing, thus the phenomenon causing viewing area to waste occurs.In the present embodiment, described shading glue 50 is black shading glue, black shading glue has good shading performance and viscosity, can display panels 40 and framework 10 be pasted fixing, thus make the present invention have good reliability, can run under high/low temperature condition, and there is good high-temp resisting high-humidity resisting and the ability of thermal shock, prevent light leak.Certainly, described shading glue 50 is not limited to black shading glue, and described shading glue 50 can also select black and white shading glue.
The present invention also provides a kind of mobile phone, and described mobile phone comprises aforesaid narrow screen Rimless LCDs.
Assembling process of the present invention is as follows:
First, by glue frame 11 and chase 12 integrated injection molding;
Then, reflector plate 41, light guide plate 42, diffusion sheet 43, lower brightening piece 44 and upper brightening piece 45 are stacked in cavity 13 from lower to upper successively, and ensure that the gap between described reflector plate 41 to framework 10 medial margin is 0.1 ~ 0.15mm, described light guide plate 42 to framework 10 medial margin between gap be 0.05 ~ 0.1mm;
Then, by special fixture, the one side of shading glue 50 is pasted in framework 10, and ensure the lateral border of described shading glue 50 to screen body 30 lateral border between the fit-up gap X2 that formed be 0.05 ~ 0.1mm, the medial margin of described shading glue 50 to display panels 20 viewing area 21 between distance X4 be greater than 0.35mm;
Finally, by special fixture, display panels 20 and the another side of shading glue 50 are pasted fixing, and ensure that the fit-up gap X1 formed between the left and right lateral margin of described display panels 20 to the left and right lateral margin to screen body 30 is 0.1 ~ 0.14mm.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
