Abstract: An anti-peep display device includes a display module and an anti-peep module disposed on the display module. The anti-peep module includes the following features. The first light incident surface faces the display surface, the second and third light incident surfaces are located on opposite sides of the first light incident surface, the first condensing portion is disposed corresponding to the second light incident surface and the first light source, the second condensing portion is disposed corresponding to the third light incident surface and the second light source, the first and second condensing portions convert beams of the first and second light sources into anti-peep beams with a beam angle less than 10 degrees, and the optical microstructures reflect the anti-peep beams and exit the anti-peep beams from the light guide plate. The present invention also provides an anti-peep method applicable to the anti-peep display device.

Abstract: A stacked computer system includes a main machine module and expansion modules detachably stacked with each other. Each of the expansion modules is electrically connected to the main machine module. Each of the main machine module and the expansion modules includes a first connector located at an upper position and a second connector located at a lower position. In any two of the main machine module and the expansion modules adjacent to each other, the first connector of a lower one is connected to the second connector of the other one. Each of the first connector and the second connector includes at least two of a data transmission control interface, a power supply interface, a display signal transmission interface and a detection interface.
