Strobe signals are output in one of five patterns, depending on the number of dot lines that are simultaneously ON.
The following table shows each of the patterns.
Figure 2-7 shows the timing for Pattern (5).
Number of ON Elements per Dot Line
0 STB1+STB2+STB3 384
193 STB1+STB2+STB3 384
STB1+STB2 192
193 STB1+STB2+STB3 384
STB1+STB3 192
193 STB1+STB2+STB3 384
STB2+STB3 192
385 STB1+STB2+STB3 576
STB1: Number of ON elements in element range 1 to 192.
STB2: Number of ON elements in element range 193 to 384.
STB3: Number of ON elements in element range 385 to 576.
