Hi,

I´m looking for a big graphic display (around 3'') with a wide temperature operation. It has to be Sunlight Readable. It will be in a bike.
I´m thinking in a 4D System or GLDC (KS0108 or T6963). I would like something with controller,because I would like to control with Mega.

¿Any recommendation? I´ve looking CrystalFonz displays...
If it´s possible with color feature, it´ll be fantastic...


Thank you


Regards,



Igor R.

According to this Mouser page, those things are 300 dollars: http://www.mouser.com/Search/Refine.aspx?Keyword=790-EDIPTFT43-A

Have you had a look at the LiquidWare TouchShield Slide: http://www.liquidware.com/shop/show/TSL/TouchShield+Slide

Exist others cheaper, it depends of  the model...

I´m not sure that a TFT or Oled will be sunlight redeable...When I try to see something in my PDA outside, it´s difficult...

It will be fitted on a motorbike... I need something redeable with high bright, wide temperature range and the electronic inside must resist vibrations.

Graphics LDC are the best in price... for sure....But nowadays are quite "retro" design.....je,je,je   :D

OLED is sun readable.

Igor R

And what about life of this technologies? Because I´ve read that Oled are 20k hours...

Are you expecting to run your bike for that many hours?  If you average 25 miles per hour you would be able to travel a distance greater then that to the moon and back before you used up the 20k hours.

It used to be that the blue's had a life of about 20k hours but nowadays the blue is more like 40k hours and the other colours much higher. It depends if you go for a decent display or not... Depends on price a little bit.

Anyway, what's wrong with a dot graphic display? who doesn't like a bit of retro?  8-)

For temperature you could just use a 20x4 display and use some 4 line text for BIG NUMBERS...

Mem,You don´t have to think only in application with the motorbike in movement....
There are 2'3 years...
You imagine that the display of your car break down in 5 years .... ;)

It´s not to show temperature... I need that the display works in a wide range of temperature... like -20 to 80ºC.

The application will be like an onboard computer.... ;)

Of course, with a gldc an a little of design could be something cool

20k operating hours in my car would take 60 years  ;)

Anyway, if you do decide to go retro, I have a nice GLCD library for you to use:  http://www.arduino.cc/playground/Code/GLCDks0108  :)

Normal commercial electronics is only specked for 0 to 70C. Going outside these ranges costs you a lot more. A military specified display is going to cost about 5 to 10 times more than a commercial display.

I´ve found CrytalFontz which has -20 to 70ºC.
With T6963 controller and 160x128 (101 x 82 mm).
It seems good!!

Any experience with this company? Another similar?
