Note :

If H-drive is taken on Pin 20 (Pin 21 connected to supply), H-D is the ratio of low level duration t o horizontal period.

If H-drive is taken on Pin 21 (Pin 20 grounded), H-D is the ratio of high level duration to horizontal period.

In both cases, H-D period driving horizontal scanning transistor off.
