1. Find out what driver chip your display has
2. Find a graphics library which supports that chip
3. Study the documentation and examples for that library.

As we're on the ST forum and talking about an STM32, you might try this:

http://www.st.com/en/embedded-software/stemwin.html

 

There's also Arduino:

Many discovery boards - and other 3rd-party boards - feature LCDs; so you could study how they do that.

Many, many people have published stuff on the interwebs - gave you tried Google ?

eg,

So keep searching for one which does, then!

Did you look at 

http://www.st.com/en/embedded-software/stemwin.html

 

Or Arduino?

Or 

http://stm32f4-discovery.net/2015/07/hal-library-12-lcd-for-stm32fxxx/

 

Or Google ?

Hello, ı think this stemWin study with hall driver. I want to try to standard pripheral. can ı do this? how?

Both HAL and the Standard Peripheral Library just address the very lowest layer - getting the bits across the SPI interface, or whatever.

Dealing with images is a very much higher-level thing.

If you want SPL versions of stemWin you might have to ask for specific older versions

I uploaded this one to the mirror back in mid-2014, but I have newer and older versions

AIUI the 'HAL' in 

http://stm32f4-discovery.net/2015/07/hal-library-12-lcd-for-stm32fxxx/

  is nothing to do with ST's current product called 'HAL' - the libraries at 

http://stm32f4-discovery.net

  are based on the 

Standard Peripheral Library (SPL) ?

Also note that emWin itself is a Segger product - not specific to ST:

https://www.segger.com/products/user-interface/emwin/

 

So, if you want to implement the low-level stuff yourself, perhaps go for the generic Segger version?
