| Help,Can ordinary LEDs replace thin-film LEDs? |
| << < (5/7) > >> |

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. |

Due to the long time of use, the display effect is very bad. Is there a better and more feasible upgrade solution? |

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. |
