Redmi, a Xiaomi spin-off phone brand, says it has made in-display fingerprint sensors that work with LCD screens. Previously, only OLED screens supported them.

It uses an ultrasonic sensor, ... The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and ... an Arduino Uno, a 16x2 LCD, ...

When you power the Ultrasonic Experiment board up in range finder mode, the LCD will read out the distance between the sensor and the object that it is lined up with in centimetres.

In-display fingerprint scanners use a camera to take an image of the finger, and OLED panels allow light to pass through the display and reach the sensor. In contrast, LCD panels do not transmit ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

Now, Redmi is showing off a new under-display fingerprint sensor that works through an LCD panel. So far, under-display fingerprint sensors have only been possible on OLED displays.

Whereas a typical scale would then simply show the resulting number on an LCD display, [Mirko] decided to use a moving coil meter driven by the Arduino’s analog output.
