Description

A kind of boundless LCDs of narrow screen of mobile phone

Technical field

The utility model relates to a kind of mobile phone display screen, the boundless LCDs of particularly a kind of narrow screen.

Background technology

The display panels of prior art is contained in (as shown in Figure 1) in the glue frame at present; the glue frame is with or without chase outward; because all there is the thick protection of glue glue frame four sides of being packed into around the display screen; like this; the mechanical strength of LCD MODULE product, structural rigidity ,/ESD/EMI/EMC performance, reliability etc. are all guaranteed; but do not satisfy narrow screen, boundless requirement; new mobile phone products form emerges in an endless stream at present; wish that the LCM screen is near more good more apart from the mobile phone two sides on the mobile phone, therefore mobile phone can have characteristics such as " screen is big ", " richer visual impact ".Accomplish that simply the LCM that requires like this shields, and removes both sides glue frame exactly.

Summary of the invention

At the technical deficiency of above existence, goal of the invention of the present utility model is to provide a kind of boundless LCDs of narrow screen of mobile phone.

Goal of the invention of the present utility model is achieved by the following technical solution:

A kind of boundless LCDs of narrow screen of mobile phone, comprise: display panels, back light system, glue frame, chase, fit-up gap, LCD V/A district, LCD A/A district, antistatic insulating lacquer, black and white shading glue, light source, FPC pad backlight, FPC backlight, main FPC, conducting resinl, described chase and glue frame one are injection molded, (display panels glass edge 2mm is a glass cement sealing frame to the characteristics of consideration display panels, non-AA district in this scope), finish by 2mm Jiao Feng district, two sides the location on the Width of display panels glass.Being distributed in everywhere on four angles of location display panels glass, thereby can effectively locate.It is very near that such design has avoided chase in traditional boundless design to be directly adjacent to the ITO electrode workspace (AA district) of TFT glass, directly the ESD problem is easily taken place in ITO electrode workspace (AA district) discharge behind the chase static electricity gathered lotus, the inboard spraying of chase antistatic insulating lacquer, the outside is provided with conducting resinl.Described LCD MODULE screen width dimensions=glass width dimensions+2X fit-up gap (0.05 ~ 0.1)+2X chase thick (0.15 ~ 0.2).Described FPC anti-convention backlight design is welded in the inboard after the bending of main FPC, and peripheral components layout on this position of the good main FPC of appropriate design, the thickness 0.12mm of FPC backlight like this is with regard to shared chase thickness space 0.15mm, simultaneously, FPC backlight and FPC pad design backlight drop on outside the LCD V/A district, even pad has 0.1mm highly instead to push up, can not influence whole effect backlight yet.

The reliability design of back light system has carried out pasting the innovative design of black and white shading glue.Entire backlight system (3 tunics such as brightness enhancement film, light guide plate, reflectance coating)/LED lamp bar, form the inner chamber of a sealing by black and white shading glue, chase and the injection moulding of glue frame one, chase two sides designs is higher than black and white shading glue plane 0.55mm, has guaranteed good back light system reliability (high low temperature, hot and humid, salt fog etc.).Prevent light leak, reduced the gap, improved the reliability of back light system.

Embodiment

How further specify the invention of the design's method below in conjunction with accompanying drawing realizes:

Embodiment:

As shown in Figure 1, existing display panels 1 is contained in the glue frame 3, and the glass of display panels 1 is contained in the glue frame 3, and the glue frame is provided with chase 4 outward, does not satisfy narrow screen, boundless requirement.

Shown in accompanying drawing 2,3,5,6,8, chase 4 and glue frame 3 one are injection molded, consider the characteristics of display panels 1, display panels 1 glass edge 2mm is a glass cement sealing frame, non-AA district in this scope, finish by 2mm Jiao Feng district, two sides the location on the Width of display panels 1 glass.Being distributed in everywhere on four angles of location display panels 1 glass, thereby can effectively locate.Such design has avoided that chase is directly adjacent to display panels 1 in traditional boundless design, the ESD problem directly easily takes place to the discharge of AA district, ITO electrode workspace behind the chase static electricity gathered lotus in the very near display panels 1 in the LCD A/A district, ITO electrode workspace 7 of TFT glass.Described LCD MODULE screen width dimensions=glass width dimensions+2X fit-up gap 5 (0.05 ~ 0.1)+2X iron (0.15 ~ 0.2).

Shown in accompanying drawing 9,12, for further improving the ESD performance, chase 4 inboard spraying antistatic insulatings coat with lacquer 8, and the outside is provided with conducting resinl 14.

Shown in accompanying drawing 4,7,11, designed thin as far as possible thickness.FPC12 anti-convention backlight design is welded in the inboard after the bending of main FPC13, and peripheral components layout on this position of the good main FPC13 of appropriate design, the thickness 0.12mm of FPC12 backlight like this, with regard to the shared thickness space 0.15mm of chase 4, simultaneously, FPC12 backlight and FPC pad backlight 11 designs drop on outside the LCD V/A6 district, even pad has 0.1mm highly instead to push up, also can not influence whole effect backlight.

As shown in Figure 10, for preventing light leak source 10, the reliability design of back light system 2 has carried out pasting the innovative design of black and white shading glue 9, entire backlight system (3 tunics such as brightness enhancement film, light guide plate, reflectance coating)/LED lamp bar, by the inner chamber of black and white shading glue 9, chase 4 and a sealing of glue frame 3 one injection mouldings formation, chase 4 two sides designs is higher than black and white shading glue 9 plane 0.55mm, has guaranteed good back light system reliability (high low temperature, hot and humid, salt fog etc.).Prevent light leak, reduced the gap, improved the reliability of back light system 2.
