    Explanation of delay function in lcd

    Hi Vyshnavi

    The datasheet of LCDs demand such delay in between switching of its pins or ports, this might be because such LCDs contain a controller within themselves which further interprets the data or command we send using a microcontroller or something similar, and helps to finaly dislpay the result over a liquid crystal screen. Although this delay thing is very small in value but plays a significant role in LCDs functioning.

    Hope this clears your doubt :)

    you can also program LCD without delay. in that case you have to check busy flag in LCD. LCD is slower device than any micro controller. so there is a need of hand shake signals or to provide delay in between to send data to LCD
