Above is a picture of the component.
I like to know where to buy them.

If you can't find it, you might look for or design your own break-out board to fit the same space and do the same function. For example, Spark fun sells one (https://www.sparkfun.com/products/9695 ) that is 20.35X30.5 versus what you have that is 17.4x33.9 (all in millimeters).

I2C is a problem.
I cannot use that in the existing PCB

 

The chip used by SF has I2C and the lines are brought out:


Of course, you would probably need to do some freehand connections (Manhattan style), and this option would not be my first choice. But it is an option assuming you have exhausted trying to find that chip. Have you tried electronic junk yards to find parts?

No junk yard.
and the uC on board does not use I2C. It uses simple logic level inputs

It looks more like it is just a demo board, not practical for an application.

 

I can't find the component you're looking for, but if you're seeking something with an ordinary logic-level interface (i.e., not I2C) then you might consider Atmel's AT42QT1010 (single channel) or AT42QT1070 (7-channel) chips. Digi-Key carries them.

I dunno what you mean by a demo board. If you referring the pcb in the picture, then is it not demo. I need to find a solution for that touch panel.

Seems a bit complicated for my repair.

A demo board is a board designed to show how certain component or chip works. Apparently what you have is not such a thing.
