As depicted in figs. 1 and 2, one of an embodiment of the present invention display device 100, for as smart phone,
The mobile terminals such as tablet computer.
As shown in connection with fig. 2, which includes display panel 10 and flexible circuit board 20, and display panel 10 includes
Viewing area 10a and multiple first pads 11 set on the periphery viewing area 10a, viewing area 10a can be used to show mobile terminal
Picture or carry out touching manipulation etc. for user.First pad 11 is obliquely installed in display panel 10.Flexible circuit board 20 is set
There are multiple second pads 21, the second pad 21 and the first pad 11 correspond, and the shape of the second pad 21 and the first pad 11
Shape matches, so that second pad 21 is at least partly bound to corresponding when flexible circuit board 20 is connected with display panel 10
First pad 11, so that electric current or data can be transmitted between flexible circuit board 20 and display panel 10.Due to the first pad
11 opposite display panels 10 are obliquely installed, thus 21 relative flexibility circuit board of the second pad, 20 court to match with the first pad 11
Opposite direction inclination, binds together so that the second pad 21 is corresponding with the first pad 11.
In some embodiments, display panel 10 can be liquid crystal display (Liquid Crystal Display, LCD)
Or the display screen of the types such as organic light-emitting diode (OLED) display screen (Organic Light-Emitting Diode, OLED), herein
It is not construed as limiting.
As shown in Figures 2 to 4, when the first pad 11 and the second pad 21 are placed towards a face, the first pad 11 and
The inclined in opposite directions of two pads 21, so that second pad 21 is with soft when flexible circuit board 20 connects display panel 10
Property the overturning of circuit board 20 and, corresponding first pad 11 and second pad 21 in the same direction inclination opposite with the first pad 11, Jin Erneng
Flexible circuit board 20 together, is electrically connected at display panel 10, it can display panel 10 and flexible circuit board by enough matchings
Electric current or data can be transmitted between 20.It carries out for example, being assemblied in mobile terminal in display device 100 in use, mobile terminal
The power supply units such as battery display device 100 can be given to power by flexible circuit board 20.
In one embodiment, the first pad 11 can tilt in the same direction, can also tilt towards different directions.It can
To be configured according to actual needs, with the arrangement space on reasonable utilization display panel 10.
In display panel 10 as shown in Fig. 2 and Fig. 3, the first pad 11 tilts in the same direction along the edge of display panel 10, then
As shown in figure 4, the first pad 11 is equally the edge distribution along display panel 10, positioned at the first of 10 left area of display panel

The adverse effect of effect is bound, to ensure the validity being electrically connected, improves the quality of display device 100.
As shown in connection with fig. 5, the inclination angle alpha at the edge of the opposite display panel 10 of the first pad 11 is 60 degree to 75 degree.It should
Under tilt angle, it can either ensure that enough first pads 11 can be arranged in display panel 10, also can effectively decompose binding
Offset in the process enables the second pad 21 to be connected to the first pad 11 and realize flexible circuit board 20 and display panel 10
Between connection, to transmit data or signal.
As depicted in figs. 1 and 2, flexible circuit board 20 is equipped with display driver chip 22, display driver chip 22 and the second weldering
Disk 21 is connected.Display driver chip 22 can be connected by way of PCB layout with the second pad 21, thus the second pad 21 with
When first pad 11 is connected, display driver chip 22 is connected with display panel 10, to transmit data or signal.
In one embodiment, display driver chip 22 and the second pad 21 are located at the same side of flexible circuit board 20.It is soft
Property circuit board 20 there is bending part 20a, and bending part 20a is between the second pad 21 and display driver chip 22.Such as Fig. 1 institute
Show, when the second pad 21 is bound to the first pad 11, the edge phase of the bending part 20a and display panel 10 of flexible circuit board 20
Right, display driver chip 22 covers the back side 10b in display panel 10 with flexible circuit board 20, so that display panel will not be occupied
The side of 10 setting viewing area 10a, that is to say, that the viewing area 10a of display panel 10 can be made big as far as possible, to realize
The pole narrow frame of display device or comprehensively screen design.
The part that display driver chip 22 is arranged in flexible circuit board 20 can be adhesively fixed by OCA adhesive-layer in display surface
10 back side 10b of plate, to prevent display driver chip 22 from occurring loosening and influencing to be electrically connected.OCA optical cement (Optically
Clear Adhesive) there is colorless and transparent, high light transmittance, high adhesion, high durable, water resistance, high temperature resistant, uvioresistant etc.
Feature, and have controlled thickness, uniform spacing can be provided, for a long time using will not generate yellow, remove and go bad
Problem.Optical cement is one of the raw material of important touch screen, is a kind of two-sided fitting adhesive tape of no basis material.
Again as shown in Figure 1, display device 100 includes colored filter 12, colored filter 12 is covered in display panel 10
Viewing area 10a, to improve the transmitance of fingerprint reflected light, conducive to the sensitivity and accuracy for improving fingerprint recognition.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
