got the pinout for an sharp lcd but dont understand what they want to tell with it. Flat Panel Connections CM112/110 Connections Signal Pin Pin Signal Comments S 1 <> 11 FLM - CP1 2 <> 10 LP - CP2 3 <> 13 SHFCLK - Vdd 4 <> 1 Vddsw - Vss 5 <> 6 GND Vee 6 <> 4 Vee- - Vss 7 <> 9 GND - DU0 8 <> 18 PNL3 Data bits are in reverse order. DU1 9 <> 17 PNL2 - DU2 10 <> 16 PNL1 - DU3 11 <> 15 PNL0 - DL0 12 <> 22 PNL7 - DL1 13 <> 21 PNL6 - DL2 14 <> 20 PNL5 - DL3 15 <> 19 PNL4 - whats about the DU,DL,Vss where is Hsync and Vsync? |

Hey antiHero. Think we are looking at more or less the same document. This is what i have found in other docs, anybody correct me if i'm wrong. SHFCLK clocks in 8 pixels from DU & DL. LP must be high for the last SHFCLK on the line, ie similar to h-sync. FLM must be high for the whole of the last line, similar to v-sync. Vss=GND Vdd=+5V Vee=-17V Re DU/DL: The screen is devided into upper half and lower half. With each SHFCLK 8 pixels are clocked it, 4 in the upper half(DU0-DU3) and 4 in the lower half(DL0-DL3). The four pixels are next to each other, on the same line. Hope this helps... Which LCD is this? BTW, i have a very bad quality PDF of another Sharp LCD that explains the wave forms... But it isn't very readable... Thanx, r |

Beware: My Sharp(LM64P83) also has 15 pins but in a slightly different configuration. As to connecting it to a VGA card, not easily, unless the card has provision for an LCD. You can look at: http://eio.com/lcdconnect.htm |
