Review on High-Quality 1.3inch LCD Display HAT for Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/Zero WH - IPS, 240x240 Pixels, 65K Display Colors, SPI by Shane Solorzano

like OLED electronics

In the past, the main disadvantage of TFT technology was the low contrast. With In-Plane Switching (IPS), color is induced in the same plane as the backlight (the term would be misleading in this case since the light plane is no longer behind the color plane), resulting in very high contrast. This display looks like an OLED display but without the downsides of fading over time and price. Driver software is widely available - in the picture I'm using an example from Circuitpython for this chip. So far I've only driven SPI at 24MHz, which the driver chip can handle without error. With its high contrast ratio, this 2-inch display is as easy to read as larger displays. The 240 x 320 resolution gives good detail but obviously takes longer to refresh the screen, so it's a compromise. For me, IPS displays would be the best choice if available, and this display doesn't disappoint. The board allows you to solder your own wires through the through-hole, and the included breadboard-friendly wire connector makes prototyping easy and requires no soldering. I will probably use this display for my bottom line but remove the plug as it takes up too much space under the scoreboard. I tested several displays of different sizes and technologies. So far this is my favourite. What I haven't done yet are power consumption comparisons. When only a few pixels are "active", OLED usually uses less power, but I'll see how that plays out.

Pros
  • Ease of use
Cons
  • Brief instructions
