Abstract: A direct type backlight module includes a bezel, a light source, a reflecting plate and least one buffering liner plate. The bezel includes a bottom plate and a plurality of sidewalls connected to the bottom plate, and defines a receiving space therein. Each of the sidewalls includes a connecting portion and an extending portion. One end of the connecting portion is connected to the bottom plate, and the extending portion extends from another end of the connecting portion. The light source and the reflecting plate are disposed within the receiving space. The reflecting plate includes a stopping portion and a reflecting potion disposed between the light source and the bezel. The stopping portion extends outwardly from the reflecting portion and is fixed on the corresponding extending portion. The buffering liner plate is disposed on at least one of the extending portion and adjoins to an edge of the stopping portion.

Abstract: A backlight module and a display module are provided. The backlight module includes a back frame, a light guide plate, a heat sink, a light source module and a carrying frame. The light guide plate has a light emitting top surface and a light incident side surface, and is disposed on the back frame. The heat sink is disposed between the back frame and the light guide plate, and a side surface of the heat sink has a first fixing portion exposed outside the back frame. The light source module is disposed on the heat sink and faces the light incident side surface of the light guide plate. The carrying frame includes a first side wall, and is disposed around the light guide plate. The first side wall has a second fixing portion engaged with the first fixing portion, and is located outside the back frame.

Abstract: A handsaw includes a saw body, and an alignment and calibration device detachably mounted on the saw body. The saw body includes a handle and a blade mounted on the handle. The alignment and calibration device includes a housing detachably mounted on the handle of the saw body, a light emitting member mounted on the housing to emit a linear light beam outwardly, a plurality of adjusting screws adjustably mounted on a first side of the housing, and a level mounted on a second side of the housing. Thus, the alignment and calibration device is combined with the saw body to guide the sawing direction of the blade and is operated individually to form a vertical indication line, thereby enhancing the versatility of the handsaw.

Abstract: A handsaw includes a handle, a blade mounted on the handle, and a light emitting member mounted on the handle to produce a longitudinal light source aligning with a lower edge of the blade. Thus, the sawing line of the workpiece and the longitudinal light source of the light emitting member are directed in the same direction, so that a worker can drive the blade to move in the common direction indicated by the sawing line of the workpiece and the longitudinal light source of the light emitting member to cut the workpiece exactly, thereby facilitating the worker sawing the workpiece, and thereby greatly enhancing precision of sawing the workpiece.
