25 / 60 page ![]() EM62100 65 COM/132 SEG STN LCD Driver Product Specification (V1.1) 09.13.2005 •••• 19 (This specification is subject to change without further notice) 6.11 Common Control (Shift Register) 6.11.1 Common Number This circuit controls the relationship between the number of common output and specified duty ratio. Common output mode select instruction specifies the scanning direction of the common output pads, as shown in Table 8. Table 8 Common Output Pads Duty Status COM [0:15] COM [16:23] COM [24:26] COM [27:36] COM [37:39] COM [40:47] COM [48:63] COMS Normal COM[0:15] NC COM[16:31] COMS 1/33 Reverse COM[31:16] NC COM[15:0] COMS Normal COM[0:23] NC COM[24:47] COMS 1/49 Reverse COM[47:24] NC COM[23:0] COMS Normal COM[0:26] NC COM[27:53] COMS 1/55 Reverse COM[53:27] NC COM[26:0] COMS Normal COM[0:63] COMS 1/65 Reverse COM[63:0] COMS 6.11.2 LCD Driver Circuits There are 197 channel drivers that generate four voltage levels for driving the liquid crystal. The combination of the display data, the COM scan signal, and the M signal produces the liquid crystal drive voltage output. Figure 7 shows examples of the SEG and COM output waveform.
