AI summary

Disclosed is a digital type anti-glare device capable of conveniently performing input, operation and adjustment, and a method of controlling the same. The digital type anti-glare device includes a touch sensor input unit recognizing a shade degree and a grind mode level by direct selective operation or adjustment of a user as a digital contact signal and inputting the shade degree and the grind model level to the control unit, and an encoder switch input unit recognizing a sensitivity level and an opening delay level by the selective operation or adjustment of the user and inputting the sensitivity level and the opening delay level to the control unit. Accordingly, it is possible to prevent operation failure due to switch contact, dust or humidity or the like by a touch sensor and encoder input and to facilitate input, operation and adjustment even in a state in which an operator wears gloves.
