Input device of inspection system for flat panel display
View Patent ↗An input device that inputs a failure signal of a flat panel display in which a failure is found in a process of inspecting flat panel displays of a mother substrate state is provided. The input device includes an input unit that is positioned in the front of a mother substrate and spaced apart from the mother substrate and that has a plurality of labels in which a kind of a failure is written and at least one selection button to generate a failure selection signal, a guide unit that includes a first guide rail that guides horizontal movement of the input unit and a second guide rail that guides vertical movement of the input unit, a position detector that detects a position of the input unit to generate a position signal, and a controller that receives a failure selection signal from the input unit and receives a position signal from the position detector to map failure information of the mother substrate.
1. An input device of an inspection system for a flat panel display, comprising:
an input unit that is positioned in the front of a mother substrate and spaced apart by a distance from the mother substrate, a plurality of flat panel displays being formed in the mother substrate, the input unit including a plurality of labels showing kinds of failures, the input unit including at least one selection button to generate a failure selection signal;
a first guide rail that is positioned parallel to a horizontal edge of the mother substrate to guide a horizontal movement of the input unit;
a second guide rail that is positioned parallel to a vertical edge of the mother substrate to guide a vertical movement of the input unit;
a position detector that detects a position of the input unit and generates a position signal; and
a controller that receives the failure selection signal from the input unit and receives the position signal from the position detector, the controller mapping failure information of the mother substrate.
2. The input device of claim 1 , wherein the input unit comprises:
a rotation dial to which the plurality of labels is attached; and
an indication point that is positioned at the center of the rotation dial, the indication point indicating one of the labels.
3. The input device of claim 1 , wherein the input unit comprises at least two selection buttons, each of the labels being provided on one of the selection buttons.
4. The input device of claim 1 , wherein:
the first guide rail includes an upper guide rail and a lower guide rail, the upper guide rail being positioned in the front of an upper edge of the mother substrate, the lower guide rail being positioned in the front of a lower edge of the mother substrate; and
the second guide rail includes a horizontal movement member at one end thereof and another horizontal movement member at another end thereof, the horizontal movement member being coupled to the upper guide rail and the another horizontal movement member being coupled to the lower guide rail.
5. The input device of claim 4 , wherein the second guide rail includes a vertical movement member that is coupled to the input unit, the vertical movement member moving along the second guide rail.
6. The input device of claim 5 , further comprising a display unit that is provided between the vertical movement member and the input unit, the display unit displaying information that is received from the controller.
7. The input device of claim 4 , wherein the first guide rail includes a stopper provided at both ends of the upper guide rail to prevent a separation of the second guide rail.
8. The input device of claim 1 , wherein the position detector comprises:
a first sensor that is provided at the first guide rail to detect a horizontal position of the input unit; and
a second sensor that is provided at the second guide rail to detect a vertical position of the input unit.
9. The input device of claim 1 , further comprising a display unit that is coupled to the input unit, the display unit displaying information that is received from the controller.
10. The input device of claim 1 , wherein the position detector generates the position signal of the input unit at a time point when the input unit transmits a failure selection signal to the controller.
