A sawing device (10) includes a sawing machine (20), a safety module (40), and a controller (45). The sawing machine (20) has a saw blade (28). The safety module (40) has a positioning marker (41) and a visual element (43) disposed on the same side of the saw blade (28) as the positioning marker (41) and capturing the positioning marker (41) to obtain a relative position between the positioning marker (41) and a center (C) of the saw blade (28) to define a saw blade warning area (W1) based on the relative position. When a hand (50) approaches the sawing machine (20), the visual element (43) detects a position of the hand (50) to define a hand warning area (W2). The controller (45) is electrically connected to a motor (27) and the visual element (43). When the visual element (43) determines that the saw blade warning area (W1) and the hand warning area (W2) partially overlap, the visual element (43) sends a braking signal to the controller (45), causing the controller (45) to stop the motor (27).

A transparent display device (1a) and a manufacturing method of a tiled display device (51) are provided. The transparent display device includes a substrate (12), a plurality of units (14), and a first alignment mark (M1). The substrate has a display region (DR).

The second gate driver (80) has a second output terminal (A2) commonly coupled to the plurality of pixels (22). The control circuit (70) is electrically coupled to the first gate driver (30) for selectively disabling the first gate driver (30). When the first gate driver (30) is disabled, the first output terminal (A1) is in a floating state.

A battery pack includes a battery module (3010) comprising a liquid-limiting casing (0080) configured as a tubing structure and at least one cell holder (0050). The liquid-limiting casing (0080) features a cell-holder stopping structure (0140) protruding from an inner wall surface (0101) to restrict vertical movement of the cell holder (0050). The liquid-limiting casing (0080) further comprises a cell-holder fixing structure (0150) that is configured to mechanically limit displacement in every direction via a fixing fastener (0152).
