Explanation of delay function in lcd

[GANEEV SINGH]

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
