I'm just wondering what "standard practice" is for re-initializing a character-based LCD display (i.e., a 2x16 backlit LCD)? I have a project in the works now that erratically displays a blank LCD. I haven't quite tracked down what might be wrong, but I could "fix" the whole issue by just re-initializing the LCD on every pass. (This is very simply loop software..., check some inputs,

I'm trying to repair a cheap alarm clock with an LCD display. (I know this isn't worth my time but at this point I'm more curious...) A few segments of the LCD are not working and when I press the conductive tape that connects the LCD to the board, it starts to work. OK a bad connection. But am trying to buy a piece of this conductive tape and I can't find it anywhere even describe...

I had some electronics in a storage building, which flooded. I figured that most of it is junk, but I wiped it clean and put some of the stuff outside in the sun to bake dry. So far, much of it works. But two items, a GPS and a Police Scanner, both with LCD screens have very faint screens. I kind of think the water affected the LCD screens. Is there any way to get them LCD screens to work...

I have an extra pin; the R/W pin of the LCD is tied low so output always works - but I could use that pin to control the line. Does anyone read from the LCD; and if so, why?

I'm thinking of building this simple L/C meter. http://www.marc.org.au/ I've never used an LCD with a PIC before, so for the display LCD what should I be looking for? They are using a 16 x 2 LCD AMPIRE AC-162D for the L/C meter. AMPIRE Data sheet http://home.exetel.com.au/marknac/PDFs/ampire-display-specs-AC162D.pdf Would this be a suitable substitute?

I've got a "Nokia 1100" LCD, which (unless I be mistaken) is based on PCF8814, whose digital I/O range is (1.7 .. 3.3) V. The question is: is there an easy and safe way to connect it to an otherwise 3.3 V (+/- some) circuit (as in: one interfacing an SD card, or having an Arduino as its core, etc.)? (Will a few diodes suffice, for instance?) Also, the pinout for the LCD (e. g., ...

I have a bunch of battery-operated digital clocks with LCD displays. They all look good from above, but when viewed from below, the display looks blank. I want to be able to view it from bed when it's on the night stand. If memory serves, the contrast input on an LCD display changes the viewing angle. I've not taken 'em apart, but I fully expect to find a glob of epoxy covering an un...

Hi I am purchasing a custom LCD (FSTN or TFT), but I am running into limited knowledge of the actual design and production setup of LCD and the constraints involved For example, how is the routing from the COG controller to the crystals and what affects the form ratio of a display. Active area versus Visible Area and border outline So, anyone know of a reference for this. A book perhaps c...

Hi We have been getting some information on a FSTN LCD display we need, rarthe= r small, 20mm x 30mm. It is for an industrial product with 10years lifetime The problem is when we specify a resolution of 64x64 pixels, the Y pixels a= re access by the LCD controller by routing on either side of the display do= ts (on the left and right side). But, this routing occupies space, so havin= g a...

Hi, all, My shiny new (to me) HP 89441A has an analogue video output, but none of my LCD monitors can sync to it--one says "out of range" and the other two just sit there sulking. So I think that its vertical sync is too fast for them. Any recommendations for LCD monitors that can handle Y2K-ish vertical sync rates? Thanks Phil Hobbs -- Dr Philip C D Hobbs Principal Cons...

Hi. I have one problem. I need to read data from one LCD keypad but the problem is that i can not put camera in front of lcd keypad because end user will not see what is done... Is there any way to put somekind of transparent "part" to LCD , so i can pickup data and pass it to camera or serial port ? GM

Hi, Anyone know how the drive to an LCD panel works? Specifically, how one can force the display to appear "all white" or "all black" WITHOUT relying on the electronics already present in the monitor? E.g., imagine having *just* the LCD panel and being able to operate it as a "light gate" (full on, full off). Thx!

Hi. Does someone knows if there is any way to connect some tablet touch screen to raspberry model B LCD connector ? I dont want to conect it over hdmi. I was planning to connect it directly to board. Something like this but with tablet. http://www.ebay.com/itm/7-800x480-LCD-Screen-Display-Monitor-for-Raspberry-Pi-B-w-HDMI-VGA-AV-Dr iver-/301271608133 I have few used tablets and i ha

I've got a couple of bleeding LCD's. No replacements available, so it's gonna cost me ~ $1K to replace the equipment. One's in an _old_ Fluke DMM, so that's not all bad, I get to buy a new meter. :-) Ok, now to the questions: What's the average life of a properly used LCD? What causes the bleeding? Does the glass de-laminate or something? Ed

Hello I'm puzzling over my own HD44780 library for Luminary ARM. I ported the code from a working library I use with AVR. I see some activity with the oscilloscope and the signals seems ok. The LCD replies as expected. But I can see nothing on the display. I remember I should see the pixels on the LCD uninitialized after power up ii the contrast voltage is good. Actually, I can't se...

After replacing those electrolytes in the switchmode power supply the picture is also much sharper. I suspect the PLL in the electronics to be more stable due to less ripple. But more amazingly, that what I thought was burn-in of the LCD, vertical stripes strongest at the left side, something I could never get rid of with an anti burn in program, is almost gone. Could have been modulation of...

I'm after a TINY touch screen (mono) LCD display. Target module dimensions are 45mm x 35mm (max) Don't care too much about exact resolution. Does such a thing exist that's relatively easy to get? Any ideas? Thanks Dave.
