Hack A ThinkPad Display

Hackers really like their tools. This leads to holy wars over languages, editors, keyboards, and even laptops. The problem with laptops is that they age, and not always gracefully. [Syonyk] likes his ThinkPad T430S, except for one thing, its TN display wasn’t really very good. These flat screens use an older technology and show color changes with different viewing angles among other problems. So he managed to upgrade the device’s screen to IPS with the help of a replacement screen and an adapter (see right). Apparently, many similar ThinkPads can take the same sort of upgrade.

The problem is that the laptop uses LVDS to talk to the TN screen, while newer screens are likely to use Embedded DisplayPort (eDP) which is a different protocol entirely. However, there’s now a converter that [Syonyk] found on eBay (from China, of course). For about $70, the motherboard’s LVDS output can transform to eDP. Of course, you also need an IPS display panel.

Investigating The World’s Rarest Game Boy

Early last year, a very unique Game Boy Color showed up on Chinese shopping site Taobao. Rather than the rather anemic-looking display of the original GBC, this version was modified with a modern IPS LCD. Even in the pictures shown on the product page, it was clear the display on this unit was far more advanced than anything Nintendo ever packed into a Game Boy. The retro gaming community went wild, and soon the site was overwhelmed with orders. The majority of the sales were canceled by the seller, and it’s believed as few as 75 of these hacked GBCs were actually shipped out.

Thanks to one of his viewers, [Colin] was able to get his hands on one of these extremely rare customized handhelds. Clearly a man after our own heart, his first inclination was to tear the thing apart and see how they built it. While he had a fairly good idea of how they managed this hybrid of modern and classic technology, there were a couple of surprises inside.

The device has a completely stock main board, and as such works and plays like a normal GBC. But upon flipping the main board over, [Colin] found a nest of thin magnet wire connecting the new display controller to individual buttons on the front panel. As he later confirmed when he reassembled the system, this allows the user to adjust the display’s brightness by holding “Select” and using the directional pad.

As for the screen itself, the big surprise was that it’s clearly pulled out of a relatively recent smartphone. The screen is physically much larger than the opening in the GBC’s front panel, but through some software trickery the image is displayed only in the area that’s visible to the player. [Colin] managed to get a hold of a few contacts “in the know” who confirmed to him that both the hardware and software for the display controller were specifically created for this application, and are unlikely to be duplicated by anyone else.

Considering most of the Game Boy hacks we cover are about somebody jamming modern hardware into them, it’s an interesting change of pace to see a group that was so adamant about retaining as much original hardware as possible while still managing to improve the user experience.
