Patent ID: 7286217

Claim:
Apparatus for locating an object on a display panel comprising matrix-installed gate-lines and signal-lines with corresponding numbers marked thereto, said apparatus comprising: a shiftable plate; X-Y-axis driving means for driving said shiftable plate moving in X-axis or Y-axis, said X-Y-axis driving means being mechanically coupled to said shiftable plate to enable horizontal movement of said shiftable plate; coaxial-rotating means for placing said display panel thereon and performing coordinate alignment process thereto and having a grid-patterned plate, at least three slots being carved at three corners of said grid-patterned plate respectively, said three slots being made to match circumference of a circle, grid on said grid-patterned plate being used as reference coordinate when performing said coordinate alignment process in coarse adjusting coordinate of said display panel; and at lease three positioning posts being adapted by said at least three slots, one terminal of each of said at least three positioning posts being fixed on said shiftable plate, one of said positioning posts being formed as a fine adjustment gear having toothed circumference engaging to a tooth edge at inner edge of one of said at least three slots, the other of said at least three positioning posts having diameter matching width of said at least three slots, and enabling said positioning posts smoothly slide within corresponding slots, said toothed edges being forced to move by turning said fine adjustment gear, thus enabling said shiftable plate to move in angular direction, said coaxial-rotating means being installed on said shiftable plate and coupled thereto; coordinate value illustrating means for dynamically showing coordinate value of X axis and Y axis of said shiftable plate especially when said display panel is moving, thus locating said object by tracing intersection of gate-lines and signal-lines with said corresponding numbers, said coordinate value illustrating means being coupling to said shiftable plate; and a microscope for providing a cross mark in its view, thus providing reference coordinate to said coaxial-rotating means when adjusting position of said display panel to align with coordinate of said coaxial-rotating means, and to find gate-line and signal-line number on said display panel corresponding to said object, said microscope having a fixed position being installed above said shiftable plate.
