Description
Technical field
The utility model relates to LCM (English: Liquid Crystal Module, Chinese: Liquid Crystal Module, liquid crystal display module or LCD assembly) technical field, and the brightness particularly relating to a kind of LCM improves structure.
Background technology
As a rule, LCM refers to assembly liquid crystal display device, web member, control and drive integrated circult, circuit board, backlight, structural member etc. are assembled together.LCM is a kind of basic device of new and high technology, and as the display module of electronic product, it can get up with other assembling components, forms the electronic product such as mobile phone, computer.
At present, general LCM manufacturer, due to the requirement not equal factor mutually of each client, some production batch requires that brightness is lower, and some production batch requires that brightness is higher.So, in the production run of LCM, often need the brightness improving LCM.In prior art, the way of LCM raising brightness is: the quantity increasing LED in backlight module, to improve brightness.But the shortcoming of this way is: need owing to increasing LED to change backlight circuit structure, complex structure, production cost is higher.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art that a kind of structure is simple, production cost is lower, improve structure without the need to the brightness changing the LCM of backlight circuit structure.
To achieve these goals, the utility model is by the following technical solutions:
The brightness of a kind of LCM improves structure, comprise LCM main body, the top card of described LCM main body is connected to metal edge frame, the bottom of described LCM main body is connected with lower metal edge frame, described LCM main body comprises the FOG module, lustre adding layer, diffusion sheet, light guide plate, the reflector plate that stack gradually from top to bottom, described lustre adding layer comprises brightening piece, lower brightening piece, and described upper brightening piece is layered in the top end face of described lower brightening piece.
Wherein, the thickness of described upper brightening piece, the thickness of lower brightening piece are 0.1 millimeter.
Wherein, the thickness of described FOG module is 1.43 millimeters, and the thickness of described diffusion sheet is 0.1 millimeter, and the thickness of described light guide plate is 0.5 millimeter, and the thickness of described reflector plate is 0.1 millimeter.
Wherein, the thickness of described upper metal edge frame, the thickness of lower metal edge frame are 0.2 millimeter.
Wherein, described LCM main body is provided with flexible PCB.
The utility model beneficial effect is: the lustre adding layer of the utility model LCM main body adopts upper brightening piece and the stacked structure of lower brightening piece, lustre adding layer is made to have two brightening pieces, thus improve the brightness of LCM, and due to the thickness of brightening piece very thin, the integral thickness of LCM can not be affected, therefore, the brightness of the utility model LCM improves structure, without the need to changing backlight circuit structure, structure is simple, and production cost is lower.

Comprise in figs. 1 to 3:
1---LCM main body, 11---upper metal edge frame, 12---FOG module, 131---upper brightening piece, 132---lower brightening piece, 14---diffusion sheet, 15---light guide plate, 16---reflector plate, 17---lower metal edge frame, 2---flexible PCB.
Embodiment
In order to describe the technical solution of the utility model in detail, below in conjunction with the accompanying drawing of the utility model embodiment, clear, complete description is carried out to the technical scheme of the utility model embodiment.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
Please refer to Fig. 1 ~ 3, the brightness of the utility model LCM improves structure, comprises LCM main body 1.The top card of LCM main body 1 is connected to metal edge frame 11 (being commonly called as: chase), and the bottom of LCM main body 1 is connected with lower metal edge frame 17.
As shown in Figures 2 and 3, LCM main body 1 comprises the FOG module (adopting the liquid crystal display device of FOG explained hereafter, fixed also known as FOG nation) 12, lustre adding layer, diffusion sheet 14, light guide plate 15, the reflector plate 16 that stack gradually from top to bottom.Light guide plate 15 is converted to flat luminous for the light sent by the LED of side backlight module; Reflector plate 16 for the light reflection bottom directive is returned, to make full use of light; Diffusion sheet 14, for being spread apart by light, makes evenly luminous; Lustre adding layer is for increasing the brightness of luminescence; FOG module 12 comprises liquid-crystalline glasses, for display.Wherein, lustre adding layer comprises brightening piece 131, lower brightening piece 132, and upper brightening piece 131 is layered in the top end face of lower brightening piece 132, makes lustre adding layer have two brightening pieces, thus improves the brightness of LCM.
Preferably, as shown in Figure 3, the thickness of upper brightening piece 131, the thickness of lower brightening piece 132 are 0.1 millimeter; The thickness of FOG module 12 is 1.43 millimeters, and the thickness of diffusion sheet 14 is 0.1 millimeter, and the thickness of light guide plate 15 is 0.5 millimeter, and the thickness of reflector plate 16 is 0.1 millimeter; The thickness of upper metal edge frame 11, the thickness of lower metal edge frame 17 are 0.2 millimeter.Such thickness is convenient to produce, and the thickness of electronic product can not be made again excessive.
Preferably, LCM main body 1 is provided with flexible PCB (i.e. FPC) 2, and LCM main body 1 can be electrically connected with the control circuit board etc. of electronic product by flexible PCB 2, with transmission of data signals.
Compared with the LCM of prior art, the brightness of the utility model LCM improves structure, and lustre adding layer is increased to two brightening pieces by a brightening piece, thus improves the brightness of LCM.Experimentally prove: the LCM adopting a brightening piece is 180MCD by BM-7 test brightness; Adopt the LCM of the utility model two structure of light enhancement pieces, can 220MCD be reached by BM-7 test brightness; Effectively improve brightness.Further, the brightness of the utility model LCM improves structure, and without the need to changing backlight circuit structure, structure is simple, and production cost is lower.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement, all belong to protection domain of the present utility model.
