Abstract
The present invention relates to a tablet computer including a front surface and a back surface arranged opposite to each other. A display screen is disposed on the front surface, and at least one auxiliary touch screen is disposed on the back surface. When performing a touch operation through the auxiliary touch screen, hands performing the touch operation can still hold the tablet computer. Therefore, the tablet computer can be hold firmly, the hands and arms can hardly fatigue. Meanwhile, the display screen will not be covered when performing touch operation through the auxiliary touch screen. The probability of mistake touch and mistake operation are reduced. Furthermore, when the touch display screen cannot identify a touch action, the user can perform touch operation through the auxiliary touch screen. Therefore, the case in which the tablet computer cannot be used due to identify failure of the touch display screen is avoided.
