New, Better GCW LCD Screen available
« on: February 16, 2017, 06:31:22 am »
Great news, I've found a new drop-in replacement LCD panel replacement for the GCW, sourced from Digikey.

It looks better than the stock LCD, has a much wider viewing angle, and there's no pixel inversion to speak of. This is due to the difference in LCD technology; this is an MVA panel, comparable to IPS panels.

I've uploaded an album, the pictures speak for themselves:

I do offer an LCD replacement service (among other things, check my webpage linked in my signature), but it's easy enough to replace yourself if you're careful. You do run the risk of damaging your hardware, however, so I wouldn't recommend replacing it yourself unless you have a soldering iron handy in case a wire breaks off somewhere.

No modification to the firmware is necessary.

This is great, it looks delicious 8)

I'd like to know more about 3 things, compared to the stock one :
-Power consumption, because battery life of the GCW is so great !
-Response time (that would be 25/40ms according to the datasheet !? )
-What about the brightness at min/max settings ? I love the truly dimmed lcd of the Zero at minimum setting (compared to the Caanoo!)

(I don't even know the reference/specs of the stock lcd  ::) )

Anyway, this is awesome !!

The response times are equivalent to that of the old LCD, but it is a bit brighter. It still looks good on the lowest brightness, I think. I haven't tried it out outside yet (it hasn't been daytime yet :P) but I'll take some more pictures soon.

I'm not sure about the power consumption; it may be slightly higher due to the brighter backlight, but the logic circuits may be more power efficient; I'd have to test that out somehow.

Here are the datasheets, you can read for yourself (one of them defines the measures of response times, viewing angle, etc):

I need to find a source in Europe to avoid the horrible shipping :-)

Hey so to clear something up you provide the screen too (for a free of course) in addition to the labor on replacing the old screen with the new one?

I don't have two fully working GCW's on hand at the moment, but I hooked both the old screen (on the left) and the new screen (on the right) up to Playstation 2 consoles through a component interface, and loaded up the same game twice.

Here's a side-by-side comparison:

Video: both screens at default brightness.

Yep, I can order the screens. (I think I answered you in an email, but I'll clarify it here anyway.)
