LCD   Display   Daughter   Card  
For ? developers ? wishing ? to ? output ? video ? to ? a ? touch ? screen ? LCD, ? there ? is ? an ? optional ? WVGA ? daughter ? card ?
which ? can ? be ? purchased ? for ? use ? with ? the ? Quick ? Start ? board. ? The ? part ? number ? for ? the ? optional ? card ? is ?
MCIMX28LCD , ? and ? this ? card ? can ? be ? purchased ? directly ? from ? Freescale.com. ? This ? LCD ? Display ? card ? is ?
connected ? to ? J13, ? and ? occupies ? the ? Expansion ? Port. ? The ? brass ? standoff ? on ? the ? LCD ? Display ? card ? nearest ?
the ? connector ? is ? threaded ? to ? accept ? a ? standard ? metric ? M3 ? machine ? screw. ? This ? will ? allow ? for ? a ? more ?
sturdy ? connection ? if ? the ? developer ? plans ? to ? work ? with ? LCD ? display ? for ? a ? long ? period ? of ? time. ? In ? addition, ?
the ? developer ? may ? also ? wish ? to ? screw ? into ? the ? remaining ? 3 ? brass ? stand ‐ offs ? metric ? M3 ? machines ? screws ?
that ? are ? approximately ? 25mm ? long. ? The ? screws ? can ? be ? adjust ? to ? provide ? support ? to ? the ? LCD ? card ? as ? it ?
hangs ? over ? the ? Quick ? Start ? board. ? Figure ? 34 ? below ? shows ? the ? LCD ? card ? that ? is ? available. ?
?
The ? schematics ? for ? the ? LCD ? Display ? daughter ? card ? can ? be ? found ? on ? the ? freescale.com/imxquickstart ?
website. ? The ? daughter ? card ? uses ? the ? Seiko ? 43WVF1G ‐ 0 ? WVGA ? display, ? and ? provides ? all ? the ? power ?
required ? for ? correct ? operations, ? regulated ? on ? the ? Display ? card. ? Power ? for ? the ? LCD ? Display, ? with ? the ?
exception ? of ? the ? back ? light ? circuitry, ? comes ? from ? the ? MAIN_5V ? power ? source ? and ? does ? not ? go ? through ?
the ? Dialog ? DA9053 ? PMIC. ?
