With the industrial upgrading and the evolution of intelligent automation, more and more industrial instruments and meters are required to display more abundant and diverse information. Therefore, industrial instruments and meters have gradually adopted TFT LCD displays to replace traditional LED lights, seven segment displays, monochrome LCD, and mechanical instrument panels. Levetop's TFT controller chip, LT768x series, can meet such color display needs, making the new generation of industrial instruments more intelligent and practical with digital display and touch functions.
