The line number of the continuous improvement of the resolution ratio of device, flex circuit application is increasing, and taking up space constantly to increase, and is unfavorable for into one
Step reduces frame, is unfavorable for improving screen accounting.
In order to reduce the frame of display device, people use flip chip (Chip On Flex, COF) technology.Such as Fig. 2
It is shown, specifically the chip 40 of original binding on the glass substrate 10 is removed, has been tied on flex circuit application 50, flexible wire
One end binding of road plate 50 is electrically connected with LCD panel 20 on the glass substrate 10, the other end of flex circuit application 50 and master control
Wiring board 60 is electrically connected.Using this Joining Technology, chip no longer occupies the area of glass substrate, therefore effectively reduces frame
Width W, improve screen accounting, while chip is extractd and is easy, and the maintenance of display device is conducive to.But flip chip flexible wire
The production technology of road plate is complicated, and product cost is high.
Therefore, how to be achieved at low cost narrow frame liquid crystal display device is still technical problem urgently to be resolved.
Utility model content

A kind of handheld terminal comprising:
Master control circuit plate；And
The top of the master control circuit plate is arranged in liquid crystal display device, passes through flex circuit application and the master control line
The electrical connection of road plate；
Wherein, the liquid crystal display device can be narrow frame liquid crystal display device described in above-mentioned any one.
Compared with prior art, the utility model at least has the advantages that
The utility model is effectively reduced by the design of the binding position of binding position and flex circuit application to chip
Border width, improves screen accounting.Since the binding of chip still uses traditional COG (chip on glass) technology, because
This, while being also equipped with the low advantage of simple process, cost of implementation.
