So I've recently started learning about LCD communication with arduino but I have one question: Devices like PC's and smartphones use very high quality LCD's and if I wanted to use one (not necessarily with arduino) for a project, where could I find one? Whenever I look up 'high quality LCD's' it just comes up with some expensive TV's. Where can I find these kind of LCD's?

    Define quality...? Do you want well built, high resolution, good contrast ration, what? Define your parameters and then you may be able to find something suitable. – Majenko Sep 30 '16 at 18:35
  • Well most LCD's I find for arduino are text-only 2x16 green and black LCD's but it would be nice to try out using color LCD's and bigger LCD's – Max Sep 30 '16 at 18:58
  • You mean TFTs? You can get them cheap on eBay, and from places like Sparkfun and Adafruit. Personally I buy them wholesale from China... – Majenko Sep 30 '16 at 18:59

Try using search terms such as

  • "Arduino color LCD"
  • "Arduino Color TFT LCD display"

Alternatively, substitue "OLED" for "LCD" in the searches above. OLED technology is a lower power alternative to LCD. For example, see the micro OLED series, uOLED-96-G2 (Res 96x64), uOLED-128-G2 (128x128) and uOLED-160-G2 (160x128).

At the large end of the scale is the high pixel density ("retina display") 2048x1536 IPS display used in iPad 3's or 4's, the LG LP097QX1. It needs a Qualia driver board, and uses HDMI input, but can be purchased as standalone or in a plastic monitor pack.

  • HDMI sounds useful, it's an alternative to messing up my breadboard with wires all over the place! But I can't find any tutorials on sending signals through hdmi cables, let alone find a female hdmi that I can put into my breadboard to make this possible. – Max Oct 1 '16 at 6:51

    @Max! Almost all Arduino platforms are woefully underpowered for producing or even controlling color video! At best, you can control some "smart" LCD screens to display color pictures or graphics. And by "smart" I mean LCDs with built in processors that are likely a magnitude more powerful than an Arduino Uno. If you want video and HDMI you need to change your platform from an Arduino Uno to something like a RaspberryPi. – st2000 Oct 1 '16 at 20:11
  • ok. Well I looked up tft lcds and they seem to fit my needs, thanks!(I said not necessarily for arduino) – Max Oct 2 '16 at 6:56
