Brief description of the drawings
More clearly to illustrate structural feature of the invention and effect, it is entered with specific embodiment below in conjunction with the accompanying drawings
Row is described in detail.
Fig. 1 is the structural representation of the terminal device of the embodiment of the present invention；
Fig. 2 is the structural representation of the display module in the terminal device shown in Fig. 1；
Fig. 3 is the partial enlargement structural representation at I in Fig. 2；
Fig. 4 is another partial enlargement structural representation at I in Fig. 2.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.Obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of protection of the invention.
The terminal device 10 of the embodiment of the present invention is shown such as Fig. 1, terminal device 10 includes but is not limited to be mobile phone, flat board
The terminal devices such as computer.
As shown in Fig. 2 terminal device 10 includes display module 20.Wherein, display module 20 can include display screen 22.It is aobvious
Display screen 22 includes viewing area and non-display area.Flexible PCB 221, flexible PCB are provided with the non-display area
221 medial surfaces for being located at display screen 22, that is, be located at the side of the mainboard (not shown) of terminal device 10.Flexible PCB
221 are connected with the mainboard, realize the signal transmission of display screen 22 and the mainboard.
As shown in Fig. 2 further, the lateral surface of display module 20 is additionally provided with touch cover 21 so that display module 20
With touch display function.Touch cover 21 is on display screen 22.
As shown in Fig. 2 display module 20 also includes fingerprint chip 23, fingerprint chip 23 sets side by side with flexible PCB 221
The medial surface in display screen 22 is put, and in the viewing area.Fingerprint chip 23 can be attached to display screen by glued membrane
22 medial surface.The mode that glued membrane is attached connects reliability, process is simple.In other embodiments, fingerprint chip 23 can pass through
Other modes are connected with the medial surface of display screen 22.
As shown in figure 3, the end of fingerprint chip 23 draws leaded 232, lead 232 is snapped on flexible PCB 221,
Electrically connected with flexible PCB 221 with by fingerprint chip 23.Thus fingerprint chip 23 is transferred to described by flexible PCB 221
On mainboard, the signal transmission with the mainboard is realized.Lead 232 can be gold thread.The electrical conductivity of gold thread is big, corrosion-resistant, toughness
And inoxidizability is good, be conducive to the reliability of electrical connection.It is of course also possible to other conductive materials are selected according to actual needs,
Such as conducting film.
In the prior art using the terminal device of Under Display fingerprint chip technologies, its fingerprint chip includes stacking
The fingerprint chip and fingerprint chip circuit plate of setting, the fingerprint chip are electrically connected with the fingerprint chip circuit plate, the finger
Line chip circuit plate accesses mainboard, realizes the signal transmission of fingerprint chip and mainboard.But the scheme of the present embodiment eliminates described
Fingerprint chip circuit plate, is electrically connected fingerprint chip 23 with the flexible PCB 221 of display screen 22 by lead 232, Jin Erzhuan
It is connected on mainboard.Prior art is compared, the scheme of the present embodiment can reduce product thickness, be conducive to product to be thinned design.
Further, as shown in figure 3, opening up fluted 231 on fingerprint chip 23, lead 232 draws from the bottom land of groove 231
Go out.Being designed to of groove 231 moves down the extraction location of lead 232, it is to avoid lead 232 protrudes from the surface of fingerprint chip 23
And cause to interfere with other devices, it is also possible to further reduce the influence to product thickness.The shape of groove 231 and/or position
Designed according to actual needs, be not limited to shown in Fig. 3.In other embodiments, it is also possible to do not set groove 231.
Further, the fingerprint chip 23 in the present embodiment can be bare chip.The bare chip refers to the crystalline substance from groove
The wafer cell cut down on circle, be and without the chip of encapsulation.The bare chip is thinner than the chip after conventional encapsulation.
Therefore, product integral thickness is further reduced using bare chip.
Further, as shown in figure 4, being the electrical connection between protection fingerprint chip 23 and flexible PCB 221, encapsulation is used
233 pairs of lead 232 of layer are packaged, i.e., lead 232 is wrapped within encapsulated layer 233.The material of encapsulated layer 233 include but not
It is limited to EMC (Epoxy Molding Compound, epoxy molding material).
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
Those familiar with the art the invention discloses technical scope in, can easily expect various equivalent modifications or
Replace, these modifications or replacement should all be included within the scope of the present invention.Therefore, protection scope of the present invention Ying Yiquan
The protection domain that profit is required is defined.
