Figure 2.16.8 Display position
2.16.2 Display Position
The display positions of characters are specified by a block. There are 16 blocks, blocks 1 to 16. Up to 32
characters (32-character mode)/42 characters (42-character mode)/ can be displayed in each block (re-
fer to 2.16.6 Memory for OSD).
The display position of each block can be set in both horizontal and vertical directions by software.
The display position in the horizontal direction can be selected for all blocks in common from 256-step
display positions in units of 4 T
The display position in the vertical direction for each block can be selected from 1024-step display posi-
tions in units of 1 T
Blocks are displayed in conformance with the following rules:
• When the display position is overlapped with another block in the same layer (Figure 2.16.8 (b)), a low
• When another block display position appears while one block is displayed in the same layer (Figure
block number (1 to 16) is displayed on the front.
2.16.8 (c)), the block with a larger set value as the vertical display start position is displayed. However,
do not display block with the dot size of 2T
In the case of OSDS/P mode block: 20 dots in vertical from the vertical display start position.
In the case of OSDL mode block: 32 dots in vertical from the vertical display start position.
In the case of CC or CDOSD mode block: 26 dots in vertical from the vertical display start position.
Note: VPi (i = 1 to 16) indicates the vertical display start position of display block i.
