Abstract: A trackball module structure is provided. In the structure, a Hall IC is integrated in a flexible printed circuit, and the integrated structure and a trackball device are disposed on the base to be located. Afterwards, a lid is used to fix the integrated structure and the trackball device to form a module. The module is easy to be disposed on an electronic device. This not only solves the problem that the conventional trackball is hard to locate, but also prevents the ESD with the cooperation of a metal base and a metal lid.

Abstract: A display device includes a display panel having a back cover, a body, a supporting plate and an adjusting mechanism. The adjusting mechanism includes a sliding rail support, a sliding block, a gear and a rotating member. The sliding rail support is fixedly connected to the back cover, and has a guiding structure disposed along the sliding rail support. The sliding block is slidably provided at the sliding rail support to move along thereof. The gear is connected to the sliding block. The gear and the guiding structure are clenched to position the sliding block at the sliding rail support. The rotating member has a first connecting portion and a second connecting portion. The first connecting portion is fixedly connected to the supporting plate, and the second connecting portion is pivotally connected to the sliding block, thereby adjusting the relative angle between the supporting plate and the sliding block.
