Display swap with T6963C ?

Display swap with T6963C ?

2019-09-12 by nebelfuerst@...

As my backlight is dead, I tried to avoid disassembling the LCD by buying a replacement LCD.

I read somewhere, that the type should be compatible with T6963C.

So I bought this one:

https://www.ebay.de/itm/Powertip-LCD-Grafik-Display-24064-GLCD-240-64-PG24064E-PD-T6963C-1-Stück/311819406726?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649


I connected everything except the 100V. The display became black, without any letters visible.

Did anyone replace the complete LCD yet ?

I have.  

The main issue with an LCD is setting its viewing angle.  If you look at a properly-set-up LCD dead-on, the letters will be black and the background will be white.  But if you look at it from a (say) 45 degrees angle from above, the letters will be washed-out white; and from a 45 degree angle from below, the background will be washed-out black -- your situation.

The viewing angle is normally set via a voltage value, likely between 0 and 5V.  The K5M has a "contrast" knob on the front which is attached to a potentiometer which lets you change this voltage value; but it may not be enough.  You may have to set up a little voltage divider -- basically soldering in two resistors of the right resistance -- to adjust the contrast so that the middle position of the contrast knob corresponds with dead-on properly viewed letters.

Building a voltage divider requires a bit of electronical engineering knowhow; I lucked out in getting a colleague of mine to run the math for me to figure out the right values (I had bought an LCD from Mo Morgan (lightsforsynths@...) but it wasn't adjusted right as well).  Afterwards my LCD looked great.

It is the right controller. YMMV as to the layout of the plug and
configuration of the display and connector. You might have to tweak the
contrast, twist the cable, or set a cable bridge to change the font
size.� Time for experiments - but there will be some setting where it
works.

Did you verify the model of lcd was directly swappable with your lcd?  t6963c doesn't make it directly compatiblethere could be some additional electronics you might  have to add. Also if your internal battery is dead you would get blank text

Did it come with a presoldered ribbon cable? Because the problem could also be the cable orientation

Depending on the default into which these displays start, it might be
necessary to pull up pin 17 (character width), by the way - that will be
evident if the text is cut off and oddly spaced.

Thank you all for your feedback. I will try this weekend to get the lcd working. There was no presoldered cable. I measured all 20 pins to be exactly the same like the original.
There is a capacitor labeled 220 on the old display, which i didn't transfer.

Time to give an update:
I was missing the cable between Pin 3 and Pin19 to adjust the fontsize.
Then I had to solder a voltage devider in between of the line to pin 4.
I used 4.7k resistors:

line 4 from K5 ---- (4.7k) -----*--------to pin 4 of display.
|
(4.7k)
|
GND Pin2 of display


Unfortunately, my inverter seems to be dead. It only provides 3V if a display is attached.

So I have to replace the N103-05-5 Nichia.
Do I get it right, that it uses 5V , as it is attached to the output of the 7805 ?
( Most inverters seem to use 12V.)
