Ever wondered what’s inside a head mounted spy gadget? Well, now you have the answer, there was somebody curios enough to take apart a robot toy which had a camera and eye piece, considering the size, isn’t a James Bond type of gadget so don’t expect to find any nanotechnology inside, but you can see how the LCD displays work. Even your LCD monitor uses the same solutions, only in bigger.
This post is for people curios enough to dismount similar electronics, my advice : don’t, you won’t find any components inside which you can use, or there are hard to remove from the pcb and if you damage the flexible pcb or any other part, you probably can’t repair it
