Display
controller boards for LCD and EL panels

 |
1. JED AT350, J351 ISA-bus video controller card family. The AT350 uses the Chips and Technology 65530 controller, and can drive from the top of the board to panels in the same case, or out the back of the interface card via a D25 cable to remote display panels. The J351 panel adaptors terminate the cable and juggle the wires to the individual panel connectors. They also provide positive or negative bias power for LCD panels or 24 volts for some EL panels. The JED solution is a complete kit, including BIOS, for driving a wide range of panels from Sharp and several other manufacturers. This is the data-sheet: AT350.pdf (280KB) or AT350.ZIP (133KB). A table of supported panels is at: AT350mat.pdf (10KB) or AT350MAT.ZIP (6KB). The photo: AT350.jpg (28KB) shows the AT350 and several J351 varieties.
The AT355, a new LCD/EL panel ISA interface card is in limited production. It uses the AT356 cable driver and internal panel interface card. It will work with existing J351 panel adaptors, and new ones will be released as new panels appear.
2.
JED J962 RS232/RS485 text/graphics LCD display
controller. This has a 240 column by 64 row dot-matrix display, which can
be used in graphics mode, or text mode with 8 lines of 40-character text.
It interfaces with a QWERTY membrane keyboard to make a complete alpha-numeric
terminal. It uses a Z180/64180 controller running Z80 code, which users
can program as a small instrument or plant controller. The data sheet is:
J962.pdf
(185KB), or J962.ZIP (136KB). The photo is
at J962.jpg (22KB). A rear view of the printed
circuit board is at: J962B.jpg (44KB).
3. JED J971 RS232
/RS485
two-line by 40 character ASCII text LCD display. This simple terminal can
be a simple RS232 terminal to a nearby PC or controller, or could be part
of a multi-drop network of displays or small local controllers with keyboards
(QWERTY or 16/20 keypad, user programmable) and an "I (squared) C" interface
to simple local analog or digital I/O. The data sheet is at J971.pdf
(265KB) or J971.ZIP (88KB). The photo shows
the small PCB, a 2-line by 40 LCD, and the JED QWERTY membrane keyboard
(with optional bezel): J971.jpg (42KB).
(A four line by 20 character version of this display system with RS232 and RS485 has also been designed.)
4. JED J969 RS485 multidrop 4-digit LCD display. This is ideal for applications in distributed display or remote control applications, e.g. in security, machine monitoring, batching systems, warehouses or supermarkets, with up to 128 nodes. The data sheet is at: J969.pdf (265KB) or J969.ZIP (59KB). The photo is at J969.jpg (30KB) Priced from $A200 ($A220 inc GST).

JED offers a design service for boards or systems based on a variety of displays, from small text and graphics display controllers through to flat panel EL and LCD PC-interfaced displays. We also have skills with Tigers, Xilinx gate arrays and a range of other electronic hardware and software projects. We have a group of standard display circuits, software drivers and gate array design modules and we have designed a number of custom systems based on this experience. Custom display applications by JED hook up Tigers and 8051 or AVR microprocessors in systems to GPS location systems, GSM data phones, satellite communications, truck and car computers, and a range of industrial machinery.
Several of the small display boards we have developed
involve RS485 networks, where a number of distributed displays and small
keyboards communicate over an RS485 network to a central controller.
