Notes

There are two common Nokia phone LCD modules regularly for sale. Most commonly described as Nokia 5110 boards, some are infact designed for the Nokia 3310 LCD. The two modules are functionally the same, but have slightly different wiring as one module uses a 9 pin LCD (LPH7366, Nokia 5110) and the other an 8 pin LCD (LPH7779, Nokia 3310).

The Diymore modules appear to use recycled LCDs (I have seen minute tell-tail signs of blue corrosion material as the result of expired batteries, around the electrical contacts).

The Philips PCD8544 controller uses an SPI like protocol, but can't share the bus with other devices.

Each byte written is a column of 8 bits, columns are written out from left to right, then top to bottom. The first byte represents the top, left column of 8 bits. The second represents the one to the right of it, and so on. The least significant bit is the top of the column, and then following pixels proceed downward to the most significant bit. But note that the driver libraries probably use an entirely different byte layout for bit-mapped images.

The cheaper PCB mounts for these displays have only 4 backlight LEDs compared to 6 on some phones, and the LEDs are mounted facing up, rather than sideways, horizontally across the board, so don't spread light very evenly.
