Abstract
The utility model relates to a backlight source of a display device of a cabinet type air conditioner, which aims at providing the backlight source which has the characteristics of simple structure and low manufacturing cost. The technical scheme is as follows: the backlight source of the display device of the cabinet type air conditioner comprises a rectangular framework with an opening on the surface, and a light guide plate sunk and positioned in an opening inner cavity; a brightness enhancement film and a diffusion film are coated on the surface of the light guide plate, mesh points are arranged on the bottom surface of the light guide plate, and a light-emitting component and a circuit board are fixedly arranged between the right side edge of the light guide plate and the inner side of the framework; and the backlight source is characterized in that the upper surface at the bottom of the opening inner cavity, which is used as a reflective surface of the light guide plate, and the back surface of the light guide plate are bonded into a whole, and the circuit board is a flexible circuit board. The flexible circuit board is formed by compounding a polyimide baseplate with thickness of 0.1-0.3mm with copper foil with thickness of 0.05-0.1mm. The framework is manufactured by white PC (polycarbonate).
Description
Technical field
The utility model relates to a kind of light decorations articles for use, the especially backlight of cabinet air-conditioner display.
Background technology
At present, household electrical appliance, particularly high-grade household electrical appliances widespread usage LCD, to LCD the demand of supporting backlight also increase day by day.Yet existing back light source structure is still unreasonable, is further improved, to satisfy the needs of practical application; It is complicated that the backlight of cabinet air-conditioner display particularly, its structure still show; In addition, the wiring board of this backlight is made by hard substrate, and structural modification comparatively bothers, and can't adapt to the market demand of continuous variation.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and the improvement in a kind of cabinet air-conditioner display backlight source is provided, characteristics simple in structure, low cost of manufacture that this backlight should have.
The utility model has adopted following technical scheme:
A kind of cabinet air-conditioner Backlight For Liquid Crystal Display Panels, comprise a surface be shaped on opening rectangle framework and sink to the LGP that is positioned in this open lumen; The surface of LGP is coated with bright enhancement film and diffusion barrier and the bottom surface of LGP is shaped on the site, the right edge of LGP along and the framework inboard between fixing luminescence component and wiring board; It is characterized in that being bonded as one as the upper surface of the open lumen of LGP reflective surface bottom and the back side of LGP, described wiring board is a FPC.
Described FPC is that the polyimide substrate of 0.1-0.3mm and the Copper Foil of 0.05-0.1mm are composited by thickness.
Described framework adopts white PC to make.
Operation principle of the present utility model is: after this backlight energising, the light that the LED luminescence component sends, in LGP conduction through the light at position, site (forming) by a plurality of projectioies just from the site front to LGP disperse, therefore light is just sent in the LGP front, for LCD provides back side light.
The beneficial effects of the utility model are: because framework has adopted the white PC material of highly reflective and high resistant photosensitiveness, thereby can be the upper surface of frame openings intracavity bottom directly as the reflective surface of LGP, no longer need put up reflective membrane in addition in the backlight bottom, therefore significantly simplify the structure, saved cost.And the FPC that is adopted can bend neatly according to client's different needs and turn to, thereby changes the mounting arrangement of wiring board, forms multiple constructed products, to satisfy the demand in market.In addition, the making of LGP only needs mould is changed a little, so also processing is simple, manufacturing cost is lower naturally.
Description of drawings

Fig. 2 is the structural representation of looking up of the present utility model.
Fig. 3 is the B-B structure for amplifying schematic diagram among Fig. 1.
The specific embodiment
As shown in the figure: the backlight of this cabinet air-conditioner display, comprise a surface be shaped on opening rectangle framework 2 and be fixed on LGP 1 in this open lumen; The surface of LGP is coated with bright enhancement film and diffusion barrier 6 and the bottom surface of LGP is shaped on the site (the site view omits among the figure) of reflective usefulness, the right edge of LGP along and the framework inboard between fixing luminescence component 3 and wiring board 5; Be coated with among photomask 8(Fig. 1 around the surface of described LGP and represent) with diagonal line.The projection of the transparent surface of described site and LGP (be the position of not blocked in the middle of the LGP 1, be used for the derivation of diffuse light) at its back side coincide (be both area equal and opposite in directions, both mutual projected positions overlap) by photomask 8.The above structure all structure with existing air-conditioning display is identical.
Improvement of the present utility model: the one, framework has adopted white PC; Because white PC material has the characteristic of highly reflective and high resistant photosensitiveness, thereby can be, be bonded as one with the back side of LGP the upper surface of frame openings intracavity bottom directly as the reflective surface of LGP; Thereby save the required reflective membrane of existing structure.The 2nd, the wiring board that adopts is a FPC.This FPC is that the polyimide substrate of 0.1-0.3mm (claims soft board or FPC again by thickness; Be to have height reliability, excellent flexible printed circuit) Copper Foil with 0.05-0.1mm is composited.Because the thickness of this FPC is less, thereby can be fixed on the framework of backlight to crooked turnover; Bring convenience to installment work.
Also have among the figure: wiring board binding post 7.
Claims (3)
1. the backlight of a cabinet air-conditioner display comprises that a surface is shaped on the framework of the rectangle of opening (2) and sinks to the LGP (1) that is positioned in this open lumen; The surface of LGP is coated with bright enhancement film and diffusion barrier (6) and the bottom surface of LGP is shaped on the site, the right edge of LGP along and the framework inboard between fixing luminescence component (3) and wiring board (5); It is characterized in that being bonded as one as the upper surface of the open lumen of LGP reflective surface bottom and the back side of LGP, described wiring board is a FPC.
2. the backlight of a kind of cabinet air-conditioner display according to claim 1 is characterized in that: described FPC is that the polyimide substrate of 0.1-0.3mm and the Copper Foil of 0.05-0.1mm are composited by thickness.
