Description
Technical Field
The utility model relates to a technical field is made to backlight intelligence, in particular to be used for backlight anticreep structure.
Background
BackLight (BackLight) is a light source located behind a Liquid Crystal Display (LCD) and its lighting effect directly affects the visual effect of the liquid crystal display module (LCM). The liquid crystal display does not emit light by itself, and displays a pattern or the result of its modulation of light; in the existing backlight, an FPC (flexible printed circuit) is in direct contact with an aluminum frame, as shown in FIG. 2, an aluminum wire of the aluminum frame can pierce the FPC to cause short circuit, so that large current is caused, an LED chip and electronic components in a circuit are damaged, and the components are damaged; if hua be in 13.4 cun notebook computer cases, the discovery of customer complete machine has the problem of halting, disassemble the discovery and cause for the backlight electric leakage, and then the investigation is that FPC and aluminium frame short circuit cause, to above-mentioned problem, the utility model provides a solution.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a be used for backlight anticreep structure.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a be used for backlight anticreep structure, includes aluminium frame and FPC, the U type bottom of groove of aluminium frame is equipped with the insulating layer, the insulating layer forms through insulating varnish coating on the aluminium frame to form the isolation between aluminium frame and FPC.
Furthermore, the insulating layer is made of insulating paint with the model number of QH-B061.
Furthermore, the thickness of the insulating layer is 0.006-0.008 mm.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses a coating the thick insulated paint of one deck 0.006 ~ 0.008mm at the U tank bottom of aluminium frame, increase behind the insulated paint, formed the isolation between FPC and aluminium frame, the aluminium silk can not lead to the fact the injury to FPC, can reduce the bad 10% in a poor light, very big reduction loss of enterprise.

FIG. 2 is a prior art circuit risk schematic;
fig. 3 is a schematic diagram of the circuit structure of the present invention;
FIG. 4 is a flow chart of a process for brushing insulating paint on the surface of an aluminum frame.
In the figure, 1, an aluminum frame; 2. an insulating layer; 3. and (3) FPC.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the anti-creeping structure for the backlight source comprises an aluminum frame 1 and an FPC3, wherein an insulating layer 2 is arranged at the bottom of a U-shaped groove of the aluminum frame 1, the insulating layer 2 is formed by coating insulating paint on the aluminum frame 1, and an isolation is formed between the aluminum frame 1 and the FPC3, so that an insulating effect is achieved.
Further, the insulating layer 2 is made of insulating paint with the model number of QH-B061.
As shown in fig. 3, the thickness of the insulating layer 2 coated on the surface of the aluminum frame 1 is preferably 0.006 to 0.008mm, and the thickness is greater than the surface roughness of the aluminum alloy.
As shown in fig. 4, for the process flow of the insulating paint on the surface of the aluminum frame 1, the insulating paint is coated on the surface of the aluminum alloy, the cost of the single aluminum alloy stamping sheet is increased by about 0.4 yuan, which accounts for 7 per mill of the backlight cost (the backlight unit price is about 60 yuan), the backlight defect can be reduced by about 10%, and the loss of the whole machine (4000 yuan per month of the notebook computer) is as follows: the 100 aluminum frames increase the cost: 100 x 0.4 ═ 40 yuan, backlight 10% loss of failure: 100, 60, 10% ═ 600 yuan;
the whole machine is lost: 100 × 4000 × 10% ═ 40000, input-to-output ratio: a backlight (600/40 ═ 15); the whole machine (40000/40-1000);
and (4) conclusion: the output of the model per month is about 50K, and the recoverable loss is calculated to be about 2000 ten thousand per month.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
