A 5 pin chip? There is not really such a thing. I don't think you're describing it correctly... Is the picture supposed to be showing it? If so, which part exactly?

it's look like TI TPS61040/041, but I am not sure. I can't see no reasonable label on the chip.

The part number you have posted appears to be correct. This chip would probably be used to drive the backlighting for the screen.
