Help,Can ordinary LEDs replace thin-film LEDs?
<< < (5/7) > >>
squadchannel:
The datasheet for the HV6506PJ lists the high voltage supply current as 0.5 mA, which would be difficult to drive LEDs.
Phil1977:
0.5mA can be sufficient for non-multiplexed an efficient LEDs.

But you should definitely first clarify if it´s a LC- or EL-Display. If it´s LCD then current will be far too low.

It looks like an LCD display.I usually see glass LCD,This is the first time I have seen this kind of soft plastic film.
Due to the long time of use, the display effect is very bad.
Is there a better and more feasible upgrade solution?
squadchannel:
It would be possible to make a custom board that would allow LEDs to be mounted to replace the LCD.
Can be connected with FFC cable.
VD power supply should be low voltage.

or can make a cheap FPC board with JLC.

But I don't know how to connect the LED to HV6506PJ, because HV6506PJ was originally connected to the LCD.
