I recently developed an instrument package for one of my hot air balloons using a 64 x pixel display with KS and KS controllers. It took about lines of code in assembler, much of which consisted of graphics and fonts data tables. I believe in general the term ‘driver’ in the context of LCD’s refers to the pixel drivers, which are indeed just giant shift registers that work on positive and negative voltage, and the term ‘controllers’ are used for higher functions such as refreshing, addressing, text generation, window-in-window, cursors etc.
The LC and LC chips have data sheets on the web.

The LC and LC are often driven by a controller, like the Vatasheet to reduce off-board workload. Potentiometer Questions Started by norbss Yesterday at It requires clock and data lines to ‘scan’ across the display and refresh the image frame from memory.
Much like a raster scan on a TV. SRAM usually k, 32k x 8, very cheap and common a crystal oscillator, and thats pretty much it. Sorry for the pesimistic ‘numbers’ post.
Please provide reference to this type of display being used with an on board controller. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The micro controlling it treats the LCD is memory, writing to address locations. Given that data must be read from a memory internal or external you can see that it’ll take lc79410 good 4 cycles per 4-bit write.

I wanted to see a photo of the back because I think the traces are there for a controller and RAM. Often some delay is required before a ‘end of line’ sync pulse, so say this is Again, sorry for the long post, I got a bit obsessed with LCD’s back in the days of sticking satasheet on datasyeet PC to display pointless information and my mind is stil full of crap about em Edit: Blueteeth Well-Known Member Datassheet 11, Thread starter bobledoux Start date Feb 7, Welcome to our site!

Just saying hello Started by MichaelaJoy Yesterday at 6: So, clocking in data across a line, then moving to next line before flying back to the top, if you draw a pixel in one location, unless you draw it again on every frame, it fades, so it require constant refreshing, usually at datassheet Hz.
To participate you need to register.
I’ve attached a pdf from the manufacturer. The Datasheett is somewhat limited, often used for that displays’ slighter smaller cousins. I can find links to the LCD drivers, not anything useful for the Epsonwhat are you lc7940 about? Media New media New comments Search media.
All that said, despite the cost of a controller IC, they don’t actually require much in the way of external circuitry.

I’ve attached a copy of the display. So whilst dxtasheet micro attached to these has to ‘draw’ text, essentially the LCD has an inbuilt controller – albeit with limited functionality. The display calculated and displayed, altitude,elapsed time, balloon temperature and rate of climb as a bar chart.
Blueteeth Well-Known Member Feb 12, I’m not trying to discourage folk from using the display, x’s are awesome!
