4px 寬的字型

也是在 Hacker News Daily 上看到的:「a pretty sweet 4px wide pixel font.」,看 commit log 似乎很久了,字本身長這樣:

作者有提到可以用在解析度不夠的螢幕上,馬上想到的是「Waveshare 3.2 inch Raspberry Pi LCD 320X240 Resistive Touch Screen TFT Display SPI LCD for Raspberry Pi 3 Model B/3B+/2 B/B/A Raspbian IMG Provided」這種東西:

另外用在小顆 LCD 單色顯示似乎也是個方法,不過看了一下是 5px:

出自「Real Time Clock On 20x4 I2C LCD Display with Arduino - Electronics-Lab.com」。

先記起來...

超高 PPI 的螢幕

看到「DPI Calculator / PPI Calculator」這個網站,裡面有一些有趣的小螢幕,但是有超高解析度:

1280x1024 @ 0.61 MicroOLED microdisplay (2687.21 PPI)
1920x1080 @ 0.74 Silicon Micro Display ST1080 (2976.9 PPI)
2048x1536 @ 0.83 Forth Dimension QXGA-R9 (3084.34 PPI)
2048x2048 @ 0.99 Kopin Lightning 2K (2925.57 PPI)

不過如果放寬到只要是螢幕就可以的話 (不用是彩色的),查了一下發現跟目前的進展有點遠,目前有查到的是 14000 DPI:「14,000ppi MicroLED display is world’s densest, only 0.48mm across」:

According Mojo Vision, with a world record pixel pitch of 1.8µm and a pixel density over 14,000ppi, the monochrome display technology is the company’s first important step in succeeding in its mission to deliver “Invisible Computing”, enabling people to receive and share information that is immediate and relevant without distracting them from the world in front of them.

不過考慮到彩色螢幕需要三色,上面那幾個 3000 PPI 好像已經很厲害了...

Twitter 連名字描述的部份也加長了...

Twitter 這陣子最有明得應該是 140 chars -> 280 chars,不過有媒體發現名字描述的長度也提昇了:「Twitter now lets your display name be longer too – up to 50 characters」。

You were previously limited to 20 characters, but now you have 50 to work with.

之後可以有更多奇怪的花樣了 XD

外接 iPad Retina 面板當螢幕用...

LGLP097QX1-SPA1 有被蘋果拿去當 iPad Retina 的顯示面板,但也有零賣... 於是就有人在 eBay 上面買了一張改裝:「Connecting an iPad retina LCD to a PC」。

在 eBay 買 USD$55,再把其他零件成本一起算進來,全部也才 USD$70... 是個 2048x1536 的高解析度螢幕 XDDD

下面這兩張的效果真不錯 XD
