Re: 1000PX - display backlight
¿ªÔÆÌåÓýFrank & lyford,After doing quite a few LED retrofits and several backlight replacements, my two cents: The down side to replacing the backlight is that the EL technology has limited life, 5000 to 6000 hours to half brightness, while a display with conservatively driven LED backlight will provide more than ten times that.? On the other hand, backlight replacement is relatively simple, and unless you manage to break something while installing it, it just works. The LED retrofit info on k1000.net is from 2013, so it's a bit outdated now in 2021.? Any of the 1602 (16 character x 2 line) Hitachi HD44780-based LCD modules will work, but every one I've used so far has required some degree of modification to the display and/or K1000/1200/1000_X.? The Winstar WEH001602D series OLED replacements are plug-and-play, but they appear to be obsolete, with only a few vendors in Europe showing stock now.? Prices from this Polish company are very reasonable, unless you have to pay for overseas shipping: White: ? $9.92 USD Blue: ? $9.82 USD Yellow: ? $9.74 USD It really comes down to how long you want it to last.? If you're not concerned about shorter life span, or if modifications for the LED modules seem a bit daunting, just go for the replacement EL backlight.? Either way, you'll be happy with the improvement. Regards, Brian On 3/1/21 6:16 PM, lyford wrote:
I've been following this as well, and am waiting to try once I have a free weekend to read all the docs and figures it out. There are folks who think that replacing the whole LCD is better than the backlight itself. |
