Abstract:
1. A bending test apparatus comprising: a table; a first electrode part fixing one side of a flexible substrate on the table; a guide rail disposed adjacent to the first electrode part, the guide rail extending from the one side of the flexible substrate to other side of the flexible substrate; a slider moved along the guide rail; and a second electrode part connected to the slider, the second electrode part approaching or spacing the other side of the flexible substrate to/from the first electrode part, wherein: the first and second electrode parts are clamps having grooves in which the one side and the other side of the flexible substrate are inserted, respectively; the clamps comprise a lower electrode bar and an upper electrode bar which are respectively engaged with upper and lower portions of the flexible substrate; the clamps further comprise electrode shafts coupled to both sides of the lower electrode bar; and the bending test apparatus further comprises: a movement shaft connected between the slider and the second electrode part, the movement shaft extending in a direction parallel to that of the first electrode part; and second elbows supporting the electrode shafts of the second electrode part on the movement shaft.
