A display device capable of reducing power consumption and preventing luminance changes, and a driving method thereof are provided. A spherical reference gage of known radius is measured with the stylus 1 in advance and radius values r of the tip sphere of the stylus 1 are calculated according to angle by subtracting the radius R of the reference gage from the measured values. A low-resolution display is divided into a navigation pane and read pane. A mechanical linkage couples the carriage and the socket housing for substantially vertically translating the processor relative to the socket. A terminal arrangement is connected to the first, second and third regions of the body for, in use, reverse biasing the first junction region into avalanche or field emission mode and for forward biasing the second junction region to inject carriers into the first junction region. The center portions include a shape adapted to bias the first and second contact tips toward the IC device and PCB, respectively.
