SHARP Memory Display Breakout and Example

11 posts in this topic

Always a sucker for displays of any form and shape I ordered one of the 1.35 inch SHARP LS013B4DN02 memory LCD when it made the rounds last year. At $20 apiece it's quite expensive for its size, but it's sooo pretty :smile:

I finally finished up the code and published everything on Github.

https://github.com/a...-memory-display

 

According to the datasheet, this display runs on less than 15uW. I was not able to measure current with my lowly multimeter, so I'm pretty positive that the MSP430 plus display use way below 1mA.

 

If the display looks familiar, that's because it was featured in the Wolverine teaser a few months back

My code probably also works with the breakout board that fellow 43oh member reagle designed:

According to Mouser LS013B4DN02 is end-of-life. However LS013B4DN04 has very similar specs and should also work with this breakout and code. Both displays are in stock at Mouser:

LS013B4DN02

LS013B4DN04

 

I have two extra PCBs including matching FPC connector (10pos .5mm) sitting in my drawer. PM me if anyone wants one, I'll give or trade them away as long as it's within the US.

@@bluehash The thought crossed my mind before. :)

 

Let me draft up a BP layout before I commit. I will definitely need some practical advice on layout and production from our display guru @@RobG

 

Also note that the displays are still relatively expensive. $15 a piece in quantities of 10 from Mouser:

Hey, if you design a boosterpack could you please support the zebra strip version of the displays?

 

I've bought the 96x96 and the 168x144 versions. Functionally the pin-out is identical to the FPC version, you just need another footprint.

I was thinking about this. The displays which zebra strip are cheaper and more compact. But I couldn't figure out how to press the LCD against the zebra strip without a custom-made plastic frame. Also, where do you get zebra strip?

I had lots of different sized pieces in my junk box. and as you can see I'm just using a bulldog clip to hold the screen in contact with the connector.

You can leave mounting them to the people who use those screen I guess.

 

If you're designing the boosterpack it would be nice to include both connectors. 1 on each side? the FPC could wrap around to the rear of the PCB?

Yes, adding a zebra footprint should be quite easy. The space under the edge of the display would otherwise most likely be empty anyways.

 

Are the footprints identical for both sizes of screen?

Yes, the datasheet has the specifics about pad sizes. and the 96x96 and 168x144 use identical connections.
