Abstract
The utility model discloses a kind of reflecting film structure of backlight module, comprise reflectance coating, described reflectance coating has four sides, four sides of this reflectance coating all arrange a gum, and the gum of four sides connects, the annular gum of formation one is overall, is provided with breathing breach on the whole at this annular gum, and the segmentation of annular gum entirety disconnects by this breathing breach, preferably arrange four on the whole at annular gum and breathe breach, annular gum entirety is divided into four sections of gums be separated from each other.The utility model, by improvements over the prior art, effectively solves steam and remains with thermal expansion than the inconsistent display difficult problem caused.
Description
Technical field
The utility model relates to a kind of backlight module for display unit, specifically a kind of reflecting film structure of backlight module.
Background technology
In recent years, the technology of liquid crystal indicator is gradually ripe.Along with hobby and the requirement increase of consumer, liquid crystal indicator also moves towards ultrathin gradually.For asking the object reaching ultrathin, each part of liquid crystal indicator all needs the reduction carrying out thickness, such as display floater, blooming piece and backlight module.Wherein backlight module is because of needs mixed light space, and required thickness is usually comparatively large, has therefore also become the target of mainly carrying out reduced down in thickness.
Backlight module generally all comprises the parts such as bearing frame, light guide plate, reflectance coating, and reflectance coating is a requisite vitals in backlight module.In traditional back light module unit structure, the design of reflectance coating adopts the mode of the annular gum in four sides to paste mostly, to be namely annularly sticked closed gum at the four side of reflectance coating.This frame mode is high temperature 70 degree, when humidity 90%, be easy to the problem that diaphragm deformation occurs, mainly because the material of reflectance coating and gum is inconsistent, thermal expansion is than different, so there is the phenomenon of reflecting anamorphotic, the display effect of whole liquid crystal display module can suffer thorough destruction.And adopt the mode of four sides ring seal gum due to reflectance coating, under the condition running into high temperature and high humidity, generation steam is remained, all cannot discharge for a long time, as a mobile phone falls in water, the water entering mobile phone cannot be discharged in time, and display screen can be caused to have display bad phenomenon for a long time.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of reflecting film structure of backlight module, can discharge water vapour in time, solve steam with evaporation with thermal expansion than inconsistent problem.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A reflecting film structure for backlight module, comprises reflectance coating, and described reflectance coating has four sides, and wherein two symmetrical sides are sticked separately a gum, and be separated from each other between these two gums, two other side on reflectance coating is left a blank.
Two sides that described reflectance coating is left a blank also are sticked a gum separately, make the annular gum of the end to end formation of the gum of four sides on reflectance coating one overall, this annular gum is provided with breathing breach on the whole, and the segmentation of annular gum entirety disconnects by this breathing breach.
Described annular gum is provided with the breathing breach of more than 1 or 1 on the whole.
Described annular gum is provided with four and breathes breach, breathe breach for these four and annular gum entirety is divided into four sections of gums be separated from each other.
The width of described gum is 0.5 ~ 2mm.
The length of described breathing breach is 2 ~ 15mm.
The utility model passes through improvements over the prior art, by arranging breathing breach on the gum of reflectance coating, making backlight module under running into high temperature and entering the condition of high humidity, can by breathing breach, steam being discharged timely, ensure normal display, improve the quality of whole backlight module.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment one;
Accompanying drawing 2 is the structural representation of the utility model embodiment two.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
Embodiment one, as shown in Figure 1, a kind of reflecting film structure of backlight module, comprise reflectance coating 1, described reflectance coating 1 has four sides, and wherein two symmetrical sides are sticked separately a gum 2, be separated from each other between these two gums 2, two other side on reflectance coating is left a blank.I.e. four sides of reflectance coating, only have wherein two sides to be sticked gum, and two other side is not sticked gum, and these two gums are separated from each other and do not connect.And the width of gum is 0.5 ~ 2mm.That is, be that tool is spaced between two gums, running in hot and humid situation, in time steam can be discharged, ensure the quality of whole module, ensure display effect.
Embodiment two, a kind of reflecting film structure of backlight module, comprise reflectance coating 1, this reflectance coating 1 has four sides, each side has been sticked a gum 2, it is overall that gum on four sides is interconnected to form an annular gum, and this annular gum is provided with on the whole breathes breach 3, and the segmentation of annular gum entirety disconnects by this breathing breach 3.This breathing breach arranges more than 1 or 1.In the present embodiment, be provided with four on the whole altogether at annular gum and breathe breach, breathe breach for these four and annular gum entirety is divided into four sections of gums be separated from each other.The width of gum is 0.5 ~ 2mm, and the length of breathing breach is 2 ~ 15mm.Breathing breach can be arranged on the optional position of annular gum entirety, also unrestricted at this.By this breathing breach, the steam of access arrangement can be discharged in time, ensure quality and the display effect of whole module.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
Claims (6)
