Color LCD

Started by Jim Carlson June 3, 2008
I am interested in changing from a standard LCD to a color display. Does
anyone have a recommendation on a reasonable cost

Color LCD? I am using the MSP430FG4619 and can re-assign the LCD drive ports
to interface to a 16 bit serial style unit.

Thanks,

Jim


Beginning Microcontrollers with the MSP430

Are you looking specifically for an LCD with backlight or just something
color...

I have been using an OLED color display for about 2 months now and it works
great its kinda small though
128 x 128, it only uses 4 pins from the microcontroller, but it is an SPI
interface so its nice to use the built in SPI port of the USCI module.

As a note you also need a Drive voltage of 12-15 Volts to run the display,
but no backlight is needed and the display looks great.

What is the part number? I have a SPI implementation and can easily add
another device to the bus. I had hoped to avoid having to add a boost
converter for the voltage, but for now I am only trying to get some exposure
to a color display.

Thanks,

Jim

Specifically I am using the following from onestopdisplays.com

OSD-2828GDEDF06 128x128 1.5" 18bit color display $18
single QTY
OSD-2828GDEDF06-EVK Breakout board for Prototyping $7.50
Single Qty

The EVK works wonders it allows you to break out all the connections on the
tiny flex cable to fly wires. It also allows you to put the boost converter
right on it but it only haves Pads for the boost converter circuit, you need
the following to make it work

2 - 0603 Caps (4.7pF, 0.1uF)
2 - Resistors (380k, 120k)
1 - diode (BAT760)
1 - Boost Converter TPS61040
1 - Tant Cap 10uF Size A
1 - 4.7 Inductor
1 - 500k multi turn pot.

if you want the exact parts I bought let me know I can dig them out

I first used an external PS for the drive voltage and with some sample code
was displying things in about 2 hours. The colors Are great I can provide
you with my code with some enhanced functions and a character rom table.

I will give you some more info if you need but right now I have a meeting
with the Vice president of the company to go to.

Talk to you when i get back

Tim,
I am also interested on this display solution but cannot find it on the internet. Onestopdisplays.com seems to be an unused web site and the part number you mentioned get no return on google. Do you have other directions to get them?
Thanks,

sorry about that i was going by my memory and it had a checksum error... lol

osddisplays.com

another item of note
the logic on the display uses 2.5v and it is only tolerant to inputs of 2.8V
so if you are running your MSP at 3.3V or 3V you will need to do a logic
shift. or run your MSP at 2.5v.

I am starting to work with the 240 x 400 portrait mode transreflective
display (you can see it in sunlight)

It has TFT, Memory Bus, and SPI interface (choose one). The only bad
part is that it is 1.8V so you need a level translator chip. The LED
backlight needs about 20.4 V. :(
