In one embodiment, 221 pressing connection of first connection terminal 211 and second connection end.
In one embodiment, first connection terminal 211 and second connection end 221 are connected by conductive adhesive film
It connects.
In one embodiment, first connection terminal 211 and second connection end 221 are welded by scolding tin.
As described above, the connection type of the first connection terminal 211 and second connection end 221 can be is welded by scolding tin
It connects, but there are some problems, therefore, the present invention provides the first connection terminals 211 and second connection end 221 to pass through pressing
The mode of connection.
Specifically, showing that display devices most in the market belongs to passive illuminated product, i.e. display panel at present
Image, therefore flexible circuit board (the Flexible Printed of back light unit could be shown by needing back light unit to provide backlight
Circuit, FPC, also known as flexible printed circuit board) well contacting for golden finger and pad (Pad) have to whole display device
Vital effect.
The prior art generally passes through scolding tin welding manner and realizes contact of the golden finger with pad.But it is set to cater to narrow frame
The trend of meter, pad is smaller and smaller, so that the size in leakage tin hole reduces therewith.Due to the surface tension of scolding tin itself, tin hole is leaked
It is too small that scolding tin is caused to cannot flow through leakage tin hole so that golden finger and pad can not good welds there is poor contact phenomenon, from
And cause back light unit that cannot provide stable backlight for display panel, influence display quality.
In one embodiment, the present invention provides a kind of display device and its display panel, can be avoided back light unit
The poor contact of golden finger and pad, it is ensured that stable backlight is provided.
As shown in figure 5, display device 50 can be LCD (Liquid Crystal Display, liquid crystal display), including
Display panel 51 and back light unit 52, back light unit 52 are set to the side of display panel 51 and provide figure for display panel 51
The backlight as needed for display, display panel 51 include first substrate 511 and the second substrate 512 and are located in liquid between the two
Brilliant molecule.
In one embodiment, back light unit 52 can be set in first substrate 511 separate the second substrate 512 one
Side also can be set in the side of the close the second substrate 512 of first substrate 511.And the first base is closed in back light unit 52
When plate 111 and the separate setting of the second substrate 512, first substrate 511 is thin film transistor base plate (Thin Film Transistor
Substrate, also known as TFT substrate or array substrate), accordingly, the second substrate 512 is then colored filter substrate (Color
Filter Substrate, also known as CF substrate or color membrane substrates).
As shown in connection with fig. 6, the size of the predetermined direction shown in the arrow x, first substrate 511 is greater than the second substrate 512
When size, first substrate 511 and the second substrate 512 are bonded each other, the surface phase towards the second substrate 512 of first substrate 511
It is exposed for 512 part of the second substrate.That is, being bonded each other along predetermined direction first substrate 511 and the second substrate 512
When, one end of first substrate 511 and one end of the second substrate 512 are aligned, and the other end of first substrate 511 is relative to the second substrate
512 other end is exposed, and the exposed parts of first substrate 511 can be described as at TFT step, is provided with one at the TFT step
Or multiple pads 521 (the first connection terminal i.e. above).The flexible circuit board 522 of back light unit 52 is after turning down, golden hand
Refer to that 523 (two connection terminals i.e. above) and the pressing of pad 521 connect, to can be by pad 521 and golden finger 523
Back light unit 52 is powered.
The above-mentioned of the embodiment of the present invention is designed as a kind of pressing connection, is compared to scolding tin welding, and pressing connection avoids
Scolding tin weld when leakage tin hole it is too small caused by failure welding phenomenon, that is, be conducive to display device 50 narrow frame design it is same
When, the golden finger 523 of flexible circuit board 522 and the poor contact of pad 521 are avoided, so that it is guaranteed that back light unit 52 is display
Panel 51 provides stable backlight, it is ensured that the display quality of display device 50.Certainly, due to being welded without using electric iron
Tin, therefore can reduce with risk, and the operating environment of evolutionary operation personnel.
In one embodiment, the present invention carries out golden finger 523 and pad 521 using optical pick-up apparatus (Camera)
Pressing connection is then realized in contraposition, is greatly improved aligning accuracy when connection, is further ensured that golden finger 523 and pad 521
Good contact.
In one embodiment, as shown in fig. 7, in order to preferably improve the contact between golden finger 523 and pad 521,
Conductive adhesive film 524 is provided between golden finger 523 and pad 521, so that golden finger 523 and pad 521 pass through conductive adhesive film
Realize the pressing connection.Conductive adhesive film 524 include but is not limited to ACF (Anisotropic Conductive Film, respectively to
Anisotropic conductive film), the contact area and bonding force being capable of increasing between golden finger 123 and pad 121.
In one embodiment, as shown in fig. 7, pad 521 is corroded by steam, salt fog etc. and causes short circuit in order to prevent,
Protective layer 525 (including fixation glue and protection component etc. above), specifically, protection are additionally provided at the TFT step
Layer 525 is covered in the pressing junction and is located on golden finger 523 and pad 521.Protective layer 525 includes but is not limited to
The anticorrosion glue of the types such as Tuffy glue, can also increase it is described pressing junction structural strength, prevent golden finger 523 with
Pad 521 disengages.
In one embodiment, the power supply circuit of back light unit 52 is not printed on flexible circuit board 522, but directly
It is printed on the exposed parts of first substrate 511 at the i.e. described TFT step.The golden finger 523 of the power supply circuit and the leakage
Partial surface has angle, and golden finger 523 can also be pressed with pad 521 and be connected, so that external power supply passes through pad
521 and golden finger 523 be back light unit 52 power.
Meanwhile in one embodiment, the present invention provides a kind of corresponding process flows of display device, in assembling section
In BLU (backlight) assembling process, comprising the following steps:
1. being bonded section or BD sections of supplied materials putting into ASSY producing line；
2.TPO or FOG is assembled with BLU；
3. pad cleans after assembling, UV glue, UV lamp solidification are then applied；
4.OTP/TP burning, FI/VI inspection.
The present embodiment proposes a kind of scheme by UV gluing substitution pad adhesive tape, it is possible to reduce pad adhesive tape missing, edge
Tilting problem, and backlight FPC risk of breakage can be reduced to backlight FPC reinforcement.
According to above-described embodiment:
