Hi,
Where can i find some information, how to connect panel RGB with capacitive touch i2c to board?
Here is pinout of LCD and information:

Not too difficult if you have electronics design experience.
The 40 FPC way is not the same as the Olimex LCD so whatever you do, don't use that board.
I would look at the schematic for the Olimex LCD for the digital interface and ignore the resistive touch panel connections. You'll also need a backlight driver for it. Check the specs for the LED and you might find that the Olimex driver will work. Your panel is also single 3.3V so no need for all of the high voltage circuit in their design.
Your panels digital RGB is 8 bit and so is the Olimex 7" LCD so chances are the timing should work although you may need to make small changes if needed to get a stable display.
For touch, you won't get this via the 40 way ribbon cable on the Olimex so you will have connect this to a UEXT or to one of the GPIO connections with I2C bus on it.
The CTP_RESET and CTP_INT each need to go to a GPIO pin.
Not sure what OS you are going to use but Android supports your touch but you need to add the driver to the Linux kernel and add the I2C device to the init code as I2C is not auto detected. You'll also need code to control the RESET line and handle the interrupt line you choose.
Do you have a link to the Datasheet for the display?
Hi,
I have experience, but I have no idea where connect for example Pixel clock, because i look in to schematic of Olimex displays and didin't see any similar pin.

Also i found some display with grater resolution

If i good know there is no inforation about converter on the screen.
Pixel Clock is also called the DOTCLK and on the Olimex LCD connector this is LCD_CLK.
The higher resolution is LVDS which will work with the A20 but you need to change the LCD configuration for this to work.
