If I understand this issue correctly you would like to build a circuit that converts multipin LCD display into 1-wire control. The easiest solution will be to employ a microcontroller and use its UART RX input to receive data.
An example of this you can find here:

Does it means that we can control a LCD module with just a single pin? I have access the the web site refered to and saw the schematic. It seems to me that all it does is that the io pins is shared between the keypad and LCD module. It still uses 4 data pins to transfer data to the LCD module. And I presume the LCD Enable is use for the sharing purpose.
