Display Controllers
2.1.6
Flex Connection
The connectors J17 and J18 have 16 connections on a 0.5mm pitch. This is intended to connect via a suitable FPC
socket or direct connection to an assembly which contains both the display surface and the driver device mounted on a
flex PCB.
2.1.7
Output Connectors
The segment outputs from the DA852X device are routed to a series of parallel-connected interfaces
.
Note that ALL
connectors are numbered from 1 upwards, whereas segment outputs are numbered from 0 upwards. That is connector
pin 1 is driven by DA852X signal DD0 and connector pin 20 is driven by DA852X signal DD19.
It is anticipated that the E Ink Display has a flexible tail of at least 4mm, with a pitch down to 0.2mm. Some will be
intended for direct-to-board bonding using ACF material, others will be intended to connect via an inline or low profile
FPC socket. It is not possible for us to predict all the possible variations, so we have allowed for the following:
0.2mm pitch FPC connection direct-to-board
0.4mm and 0.5mm FPC connection direct-to-board or socket (64,96 output versions only).
0.3mm narrow pitch connector with staggered pins. This gives 0.6mm pitch on solder pins
0.4mm and 0.5mm narrow pitch connector with in-line pins (64,96 output versions only).
1.27mm IDC sockets for connection via ribbon cable.
Typically, inline FPC sockets, for direct insertion of the FPC tail, are available for up to about 70 ways. Low profile
sockets, using complementary mating halves on PCB and flexible tail, are available for up to about 160ways. Typical
manufacturers are JAE, Panasonic, Hirose, Molex etc.
These connections are present on both sides of the PCB, allowing for top-side and bottom side connections. However, if
the display in use has the connections on the same side as the visible surface, it should be appreciated that part of the
display may be masked by the PCB if the flexible tail is short, as it is not possible for all the connector positions to be at
the edge of the PCB.
For such a display, there are several solutions:
a) Connect the display to the top side connectors and bend the display to make the display surface visible. The
user should take care to avoid cracking of the flexible tail.
b) Add an extender PCB (flexible or rigid) to extend the tail
c) Use an FPC socket (if available) with top side contacts.
d) Make or purchase an interface PCB to convert from FPC to wired or Insulation Displacement connector, and
use the IDC connections on the board.
