Abstract: A display system includes a display panel and an electrophoretic touch panel. The electrophoretic touch panel is optionally coupled to or separated from the display panel. When the electrophoretic touch panel is coupled to the display panel, the electrophoretic touch panel displays an input interface for inputting a signal to the display panel.

Abstract: An optical module has a support, an optical film and a buffer. The optical film has a protrusion on one edge thereof. The buffer is disposed on the support and has a corresponded notch to accommodate the protrusion.

Abstract: A reflector in a backlight module comprises a reflection layer and an electrical conduction layer. The conducting is installed on one side of a reflection layer, and is connected to the ground of the system. Thereby, when the reflector is applied to an edge-type or a direct-type backlight module, by grounding the electrical conduction layer, normal operations of devices in the backlight module will not be affected by electromagnetic interference (EMI) or electrostatic discharge (ESD).

Abstract: A guide plate of a chain saw is disclosed and the guide plate comprises: a rectangular metal plate, which is constructed by a body shaped as a guide plate and an eliminated portion elongated around the peripheral of the body; wherein the two surfaces of the front end of the body are elongated to a boundary surface of the eliminated portion individually and corresponding to two indentations of an arc portion toward front, two welded welding powder structures are inside the two indentations so as to let the top surface and the bottom surface of the metal plate be two flat surfaces, the body is separated from the eliminated portion, the welded welding powder structures are disposed at the front edge of the front end of the body, a guide groove is disposed in between the two welded welding powder structures and toward the body.

Abstract: A structure for casehardening a fixture of a guide plate of a chain saw is disclosed and comprises: a metal member being larger than the guide plate and having a slot, the dimension between the two edges of the slot being a sum of the dimension of the outer figure of the guide plate and the dimension of a tolerance, the tolerance being defined as an allowable electrode discharging distance; and at least one cooling structure being disposed around one of the edges utmostly and only having one inlet and one outlet, other useless opens being sealed by sealing structures.

Abstract: An optical module has a support, an optical film and a buffer. The optical film has a protrusion on one edge thereof. The buffer is disposed on the support and has a corresponded notch to accommodate the protrusion.

Abstract: A flat panel display including a display panel and a frame is provided. The outer edge of the display panel has a first combining portion, and the first combining portion has a guide angle. The inner edge of the frame has a second combining portion, and the second combining portion is complementary and interferes with the first combining portion in shape so as to fix the display panel on the frame.
