Furthermore, more than 20% of the Source signal output connecting wires of the driving chips are arranged in a mixed mode and are arranged below the driving chips and close to one side of the frame of the display panel, and the mixed connecting wires are arranged between the gate output array of the driving chips and the input pin array of the driving chips.
Further, more than 50% of the Source output arrays of the driving chips are arranged below the driving chips and close to one side of the lower frame of the display panel in a mixed mode, and are arranged between the gate output arrays of the driving chips and the input pin arrays of the driving chips.
Furthermore, the input pin array of the driving chip is positioned at one side of the displayable area, and the flexible circuit access terminals of the flexible circuit are synchronously positioned at the same side of the display area.
The portable display has the following beneficial effects: the driving chip adopts a part of Source (including touch pins) signal output pins to be arranged at the lowest part of the driving chip in a mixed mode (between the Gate signal output pins and the input pins of the chip). The driving chip adopts a part of Source (including touch pins) signal output pins to be arranged at the lowest part of the driving chip (between the Gate signal output pins and the input pins of the chip) in a mixed mode, so that fan-out (fanout) angles and arrangement of electric connection wires of the output pins of the driving chip are optimized, and the height from the display area edge of the display panel to the output pins of the driving chip is reduced.

In this embodiment, more than 50% of the input pins B of the driver chip 221 are arranged in the center of one side of the driver chip.
Example 4
On the basis of the above embodiment, the input pin array of the driving chip is located at one side of the displayable area, and the flexible circuit access terminals of the flexible circuit are also synchronously located at the same side of the display area.
Referring to fig. 4, in another embodiment shown in fig. 4, the number of input pins with the same name of the driving chip is optimized on the basis of fig. 3, the main input pins (which must be connected with external connection pins) of the driving chip are disposed on the side of the display area 402, and meanwhile, the flexible circuit access terminal 405 is also disposed on the side of the display area 402 synchronously, so that the free side space of the height of the driving chip can be effectively utilized to perform the routing of the input pins, and the distance from the input pins of the driving chip to the extreme edge D411 of the display can be effectively shortened, thereby further reducing the total height D412 of the lower frame of the display panel.
