Digital Dimming
The Display Dimming capabilities of the HT1632 are very versatile. The whole display can be dimmed using pulse
width modulation techniques for the ROW driver with the Dimming command. The relationship between ROW and
COM digital dimming duty time are shown as below:
Note:
(1) T=20 x tCLK(32x8 driver mode)
(2) T=10 x tCLK(24x16 driver mode)
(3) tCLK=1/fSYS
