about 320x240 LCD driver

Hi,
I have a 320x240 graphic LCD. It has 14 pins.

Here is it's Datasheet and Bottom view

I want to use this lcd in my project. Can you enlighten me about the driver?
Can I find it or which lcd driver can be similar?

Thanks.

I downloaded the datasheet,
FIRST you'll need a 24V volt power supply for the LCD driver voltage.......

2nd, find a better datasheet for the device (use Google), as that datasheet did NOT have ANY information about 'setup' or 'codes' on how to use it.

After that, check the GLCD driver that CCS supplies in the drivers folder. IF
it's a 4 bit mode driver, it _may_ work.

I always use 20x4 LCD modules, but other who do use GLCDs may reply.

edit: the CCS GLCD driver is for 8 bit modules, yours is 4, so it won't work....as coded.

This does not have any form of smart controller. This is a raw LCD. It requires
an external controller chip to allow it to be interfaced to a processor like a PIC.
It needs the entire display data sent to it line by line. Nibble at a time data,

No you cannot drive this with a PIC. You need a LCD display controller
chip between the display and the processor.

The reason there is no data about 'setup' or 'codes' is that it has none.
Just data being clocked across the bus synchronised by the frame
and line pulses....

I presume the original poster has found it and thinks 'cheap display'. The
reason it is cheap is it needs a control board to be used....
