The work is based on the development of an LCD separator machine for cell phone and tablet screens. There is a good chance that the phone screen has only the surface lens broken and not the LCD or LED screen inside. The cost of changing screens is greatly reduced with this screen separator. This machine includes a PTC heater and a quick-heating aluminium heating plate, a temperature sensor, a rotary switch encoder, a graphic display liquid crystal display (GLCD), a relay driver circuit, 30 A switch mode power, and an Arduino Uno R3 microcontroller. The LCD separator machine can be set to a maximum temperature of 150o C. It works well and has a high level of control in that the temperature is banded between upper and lower 2o C of the setting temperature. The power required is 150 W, and it heats up to 85o C in 3 minutes when the airflow is between 0.8 and 1.2 m/s, but it takes less than 2 minutes in an airtight environment.
