I believe miniLED was a marketing term intended to mislead customers into thinking it was similar technology to OLED. Since most consumers don’t even know what LEDs are, it probably worked.
LCD displays have, for some time now, had LED behind them. Said LEDs produce the white light needed to display the image produced by the LCD panel. MiniLED just provides groupings of the LED panel so that they can be individually turned off to produce darker darks.
Huge second vote for Monument Valley 1 & 2. And alto’s adventure. MV are great games that are a few hours each. Altos was addicting for a few hours easily when I first played.
