A LOW VOLTAGE LIQUID CRYSTAL DISPLAY (LCD) IS HIGHLY PREFERRABLE.
During cardiopulmonary resonance, the human electromagnetic field increases greatly. Generally, this field is oriented in the direction of the attention. The potential exists for the human field to interact with the field produced by the cathode ray tube in a negative manner.
Generally, this concern does not exist with low voltage liquid crystal displays (LCD).
