Title: Keyboard with 3-color LEDs?
Post by: FoxWolf1 on Thu, 15 November 2012, 22:29:48
So it would appear (http://english.gmarket.co.kr/challenge/neo_goods/goods.asp?goodscode=319691115&pos_shop_cd=EN&pos_class_cd=90000003&pos_class_kind=T)...though I can't read the text, so it's hard to be 100% sure. Seems to have some other interesting features as well, going by the pictures.

Anyone know more? Perhaps not my type of thing, but could be of interest to others, given that the question of multicolor backlighting comes up periodically.

I don't think that they make tricolor  LEDs in 3mm form. Or if they do, I was mistaken. Heh

It's not 3mm LEDs, it's something else, looks like a square...

Looks cool they must have found square leds that fit in the 3mm hole...

Not all LEDs need to have round housings. Poker has tiny SMD LEDs that barely has a housing at all.

Hmm, anyone who can read Hangul here mind help to translate? Especially the LED and 2 piece-design keycap parts. Thx.

I'm more interested to know how they got the 4 leads of a RGB LED into a cherry keyswitch.

I really want a look at the underside of the PCB.

These seem to be on eBay (http://www.ebay.com/itm/LETIS-Mechanical-Gaming-Media-Keyboard-LED-Backlit-Jogshuttle-Joystick-cherry-MX-/171070029624?pt=PCA_Mice_Trackballs&hash=item27d4917f38) now (with the ad translated, hooray!).

Also found a video (https://www.youtube.com/watch?v=7NTQVC76uDk) confirming that the backlights do change color, with some keys demonstrating 3 color capability.

Very expensive, but also lots of features. If only it was available with switches besides MX Brown...

To all that think the price is high, lets look at the Gmarket website price first, its $215 and lets say $30 for shipping, around $250 in total.

I'm goinmg to start of with the first impressive things I see

- Double shot keyscaps that shine pretty awesome!!!! Holly....
- LED color options
- nice slim and slick design
- extra goodies, not sure what are they but they look both like some sort of media remote control and adobe remote? the whole board looks impressive

Everything about this board screams quality, Don't matter where is made, as far as I care it can be made in China, but there is no doubt this is a very good quality board.

The LEDs changing color based on what modifier or app is running is pretty interesting.

The translated ad is a hoot to read as well.

Tri-Colour. But not individual keys.

Those are Bi-Colour LEDs!

each has 2-dies, one of blue or green or red or yellow or....

So some keys could be red/blue or red/green or green/blue, ect...

ya, those are 2x3x4mm rectangular LEDs.  That package doesn't have space for enough leads for full 3 color support.

Usually modding another color at another row only.

Here a sample of seven colors for different parts of the Deck Ice 82 keyboards

W, A, S, and D, at least, show all three colors in the video, as does the number pad.

This (for the time being known as Noppoo Nano 75) will be a tri-LED board, BUT it is still uncertain if they will keep with Cherry (as I inquired, the person incharge say they are currently finding alternative of Cherry MX and bla bla bla, no conclusion what switch will be used)

It might be possible to have RGBLED's underneath matias switches since they're clear.

I didn't watch closely enough to figure out what 3 colors... but bi-color LEDs with 2 leads can be made to emit a third color if driven with AC current, basically flashing both colors alternately fast enough that you see a 3rd..

You don't need to flash them to produce a combined colour.

Given my stated constraints there is no other way.
