Display device and color correcting method thereof

A color correcting method for a display, wherein the display has a display panel and a shaft, a correcting sensor is disposed on a first end of the shaft and a second end of the shaft is connected to a rotation axis on an edge of the display panel, the method comprising:

• driving the shaft to move along a first direction with a carrier, such that the correcting sensor is moved to a first position from a receiving position;
• driving the shaft to rotate relative to the rotation axis, such that the correcting sensor is rotated to a second position from the first position, wherein the second position is located above a display surface of the display panel;
• and
• driving the shaft to translate towards the display panel along a second direction with the carrier, such that the correcting sensor is translated to a detecting position from the second position, wherein the second direction is inverse to the first direction.

A display device, comprising:

• a display panel having a display surface;
• an outer casing configured to receive the display panel and expose the display surface;
• a shaft having an axial end and a correcting end opposite the axial end;
• a correcting sensor disposed on the correcting end, wherein when the shaft is rotated relative to the axial end, the correcting sensor is moved to a second position from a first position and faces the display surface at the second position;
• a driving module configured to translate the shaft when the correcting sensor is at the second position, such that the correcting sensor can be moved to a detecting position from the second position, wherein a distance of the second position relative to the display surface is greater than a distance of the detecting position relative to the display surface;
• a carrier on which the shaft is disposed, wherein the outer casing has an opening configured to receive the carrier, and the correcting sensor is located at a receiving position;
• a transmission device on which the carrier is disposed;
• a first drive device connected to the transmission device and configured to drive the carrier to move back and forth along the normal direction of the display surface, such that the correcting sensor is moved to the receiving position from the first position;
• and
• a second drive device connected to the shaft and configured to drive the correcting sensor to rotate to the second position from the first position.
