In the following description, the same/similar symbols represent the same/similar elements. The directional terms mentioned in the following embodiments, for example: up, down, left, right, front or back, etc., are only for reference to the attached drawings The direction of the formula. Therefore, the directional terms used are used to illustrate but not to limit the present invention.

According to an embodiment of the present invention, a display device is provided, wherein the corrector can be housed in the housing of the display device or exposed outside the display device. If the calibrator is not needed, the calibrator can be stored in the housing of the display device to keep the appearance beautiful. When the screen color of the display device is found to be degraded, the user can use the corrector to perform color correction, so that the display device can present more realistic colors.

When color correction is needed, the corrector moves to the front of the display in a translational manner, so that the corrector can be closer to the display surface to avoid interference from light sources in the external environment.

Please refer to Figures 1, 2A, and 2B. Figure 1 shows a schematic diagram of the color correction module 130 of the display device 100 assembled in the housing 120 of the display device 100, and Figure 2A shows the display device 100 in Figure 1 The corrector 118 can be rotated from the first position in the horizontal state to the second position in the vertical state. FIG. 2B is a schematic diagram showing the corrector 118 of the display device 100 can be moved from the second position to the detection position.

As shown in FIG. 1, the display device 100 includes a display panel 110, a rod 114, a corrector 118, a carrier 132, and a housing 120. The display panel 110 has a display surface 112. The rod 114 is disposed on the carrier 132. The corrector 118 is disposed at the first end of the rod 114, and the second end of the rod 114 is connected to a rotating shaft 116 on the side of the display panel 110. As shown in FIG. 2A, the first end of the rod 114 is the correction end 117, and the second end of the rod 114 is the shaft end 115.

In Figure 1, the carrier 132 is housed inside the housing 120, and the corrector 118 is located in a storage position. In Figure 2A, the carrier 132 is partially exposed to the housing 120, and the corrector 118 is located in a second position in the second position. In the figure, the corrector 118 is located at a detection position.

As shown in FIG. 1, the housing 120 is used to accommodate the display panel 110 and expose the display surface 112. The housing 120 has an opening 121 for accommodating the carrier 132 of the color correction module 130. As shown in FIG. 2A, the carrier 132 can move back and forth along the normal direction of the display surface 112 (ie, the first direction D1). The 132 has a front surface. When the carrier 132 is received in the opening 121, the front surface of the carrier 132 and the outer surface of the housing 120 are coplanar.

As shown in Figure 2A, when the carrier 132 moves forward along the first direction D1, the rod 114 moves from the storage position to the first position by the movement of the carrier 132, and then the rod 114 can be driven by The module rotates from the first position to the second position. That is, when the rod body 114 moves to the first position, the rod body 114 is driven to rotate relative to the shaft 116, so that the corrector 118 rotates from a first position to a second position. The second position is located above the display surface 112, that is, the corrector 118 faces the display surface 112 when in the second position.

As shown in Figure 2B, when the corrector 118 is in the second position, the drive module moves the rod 114 in a translational manner to move the corrector 118 from the second position to a detection position for color correction. The distance between the second position and the display surface 112 is greater than the distance between the detection position and the display surface 112. That is, the detection position is close to the display surface 112 relative to the second position. In one embodiment, the second position The distance from the display surface 112 is 1 mm, and the distance between the detection position and the display surface 112 is less than 0.5 mm, less than 0.1 mm, or there is no gap. In Figures 2A and 2B, the first movement distance S1 may indicate the distance the carrier 132 moves in the first direction D1, and the second movement distance S1-S2 may indicate the distance the carrier 132 moves in the second direction D2. The distance S2 represents the distance between the outer surface of the rod 114 and the display surface 112 when the corrector 118 is at the detection position.

After the color correction is completed, the driving module 138 translates the rod 114 so that the corrector 118 moves from the detection position to the second position away from the display surface 112. Then, the rod 114 can be moved from the second position by the driving module 138 The position is rotated to the first position, and the carrier 132 is moved to be housed in the housing 120 of the display device 100.

In the above embodiment, although the rod 114 is shown to move in the direction opposite to the normal direction of the display surface 112 (ie, the second direction D2) by the stage 132 to move the corrector 118 to the detection position, the present invention does not Limit this. The rod 114 can be directly exposed to the housing 120 of the display device 100, and the same effect can still be achieved by directly rotating and translating the driving module 138.

Please refer to FIGS. 3A to 3D. FIG. 3A shows an exploded schematic diagram of the color correction module 130 according to an embodiment of the present invention. FIGS. 3B to 3D respectively show that the driving module 138 drives the corrector 118 to translate from the storage position. To the first position, then rotate from the first position to the second position, and then move from the second position to the detection position.

In an embodiment, the drive module 138 may include a transmission device 135, a first drive device 136, a second drive device 137, and a magnetic device. 置140. The carrier 132 is disposed on the transmission device 135 so that the carrier 132 can move. The transmission device 135 may be a combination of a gear 133, a rack 134, and/or a belt to drive the carrier 132. For example, two gears 133 are arranged on the left and right sides of the carrier 132. The two gears 133 are connected by a connecting rod (not shown in the figure) and respectively mesh with the two racks 134 of the transmission device 135. The two racks 134 are arranged on a housing 131 that contains the carrier 132, and the carrier 132 and the rod 114 can also be covered by a cover (not shown) in front of them to avoid the carrier 132 and the rod. 114 exposed. The first driving device 136 is, for example, a motor and a gear set, and is connected to the transmission device 135 to drive the stage 132 to move back and forth along the normal direction of the display surface 112, as shown in FIG. 3C. The second driving device 137 is, for example, a motor and a gear set, and the connecting rod 114 rotates to drive the corrector 118 to move from the first position to the second position, as shown in FIG. 3D.

The electromagnet 142 is arranged on the carrier 132, for example, and the magnet 141 is arranged on the rod 114 near the shaft end 115. The rod 114 can selectively move in the first direction D1 or the second direction D2 relative to the rotating shaft 116. The electromagnet 142 can be energized to generate magnetic force. When the rod 114 is in the second position, the magnet 141 and the electromagnet 142 face each other to generate an attractive force or a repulsive force. Therefore, the rod 114 can be driven by the attracting force to translate in the second direction D2 to the detection position to approach the display surface 112 . When the corrector 118 is not needed, the electromagnet 142 can be energized to generate a repulsive force with the magnet 141. Therefore, the rod 114 can be driven by the repulsive force to translate to the first direction D1 The second position is far away from the display surface 112.

Please refer to FIGS. 4A to 4D. FIG. 4A shows an exploded schematic diagram of the color correction module 130 according to an embodiment of the present invention. FIGS. 4B to 4D respectively show that the driving module 138 drives the corrector 118 to translate from the storage position. To the first position, then rotate from the first position to the second position, and then move from the second position to the detection position.

The driving module 138 includes a transmission device 135, a first driving device 136, and a second driving device 137, which are consistent with the above-mentioned embodiment and will not be repeated here. The difference of this embodiment is that the driving module 138 may include a solenoid valve device 150, and the solenoid valve device 150 is used to generate a driving force on the rod 114 so that the rod 114 can move from the second position to the detection position.

In one embodiment, the solenoid valve device 150 includes a valve body 151 and an actuator 152. The actuator 152 is disposed on the shaft end 115 of the rod 114 and can be used as a rotating shaft 116 so that the rod 114 is relative to the actuator 152. Rotate from the first position to the second position, as shown in Figure 4D. When the rod 114 is in the second position, the solenoid valve is opened to cause the actuator 152 to move. Therefore, the rod 114 can be driven by the actuator 152 to translate in the second direction D2 to the detection position to approach the display surface 112. When the corrector 118 is not needed, the solenoid valve is closed to return the actuator 152 to the second position. Therefore, the rod 114 can be driven by the actuator 152 to translate in the first direction D1 to the second position, so as to be away from the display surface 112 .

Please refer to FIGS. 5A to 5D, wherein FIG. 5A shows an exploded schematic diagram of the color correction module 130 according to an embodiment of the present invention, and FIGS. 5B to 5D The operation schematic diagrams of the driving module 138 driving the corrector 118 to translate from the storage position to the first position, then to rotate from the first position to the second position, and then from the second position to the detection position are respectively shown.

The driving module 138 includes a transmission device 135, a first driving device 136, and a second driving device 137, which are consistent with the above-mentioned embodiment and will not be repeated here. The difference of this embodiment is that the driving module 138 may include an elastic device 160 for generating a driving force on the rod 114 so that the rod 114 can move from the second position to the detection position.

In one embodiment, the elastic device 160 includes a spring 161 and a stopper 162. The spring 161 is, for example, a compression spring, which is sleeved on the shaft 116 and abuts between the rod 114 and the carrier 132 to align the rod. The body 114 generates a pre-force. The stopper 162 is, for example, disposed on one side of the rotating shaft 116 for applying a reaction force to the rod 114 when the rod 114 rotates from the second position to the first position, so that the rod 114 contacts the stopper 162 to force the rod The body 114 is moved by the stopper 162 in the normal direction of the display surface 112 to be away from the display surface 112.

Please refer to FIGS. 6A to 6C, which illustrate the operation diagrams of the rod 114 and the stopper 162 of the elastic device 160, respectively. In this embodiment, the sleeve 119 of the rod body 114 is provided with a flange 1191 and a recess 1192, for example. The recess 1192 is located below the flange 1191. The recess 1192 has an arc-shaped surface. The inclined surfaces 1621 cooperate. As shown in FIG. 6A, when the flange 1191 is in contact with the stopper 162, the rod 114 is blocked by the stopper 162 and cannot move to the display surface 112. As shown in Figure 6B, when the flange 1191 is rotated to a position When the stopper 162 is no longer in contact, the recess 1192 located under the flange 1191 provides a space for the rod 114 to move in the second direction D2, and the flange 1191 can move on the inclined surface 1621 of the stopper 162. As shown in FIG. 6C, the rod 114 moves until the recess 1192 contacts the inclined surface 1621 of the stopper 162. Conversely, if the rod 114 is to return to the state shown in FIG. 6A, it is only necessary to rotate the rod 114 in the reverse direction to make the flange 1191 contact the stopper 162.

It can be seen from the above description that the elastic device 160 can move the rod 114 by changing the relative position of the flange 1191 and the stopper 162, so that the corrector 118 can be moved to the detection position.

According to the above embodiment, the present invention provides a color correction method. Please refer to Figures 1, 2A, 2B and Figure 7 for the calibration steps. First, the drive rod 114 moves along a first direction D1, so that the corrector 118 is moved from a storage position to a first position.

The second moving distance S1-S2 to the detection position, wherein the second moving distance S1-S2 is smaller than the first moving distance S1.

In one embodiment, driving the rod 114 to move closer to the display panel 110 along the second direction D2, for example, a magnetic device 140 provides a suction or a repulsive force to the rod 114 to generate the second moving distance S1-S2.

In one embodiment, the driving rod 114 is moved in the second direction D2 to move closer to the display panel 110, for example, a solenoid valve device 150 is used to generate the second moving distance S1-S2 on the rod 114.

In one embodiment, the driving rod 114 is moved along the second direction D2 to move closer to the display panel 110, for example, an elastic device 160 is used to generate the second moving distance S1-S2 on the rod 114.

In one embodiment, the rod 114 is disposed on a carrier 132. When the corrector 118 is in the storage position, an outer surface of the carrier 132 and an outer surface of a housing 120 covering the edge of the display panel 110 are the same. On a flat surface, the carrier 132 can move a first movement distance S1 relative to the first direction D1 and a second movement distance S1-S2 relative to the second direction D2.
