FIG. 1 is a schematic diagram of an optical detection device 100 according to an embodiment of the present invention mounted on a display device 10, and FIG. 2A is a telescopic arm of the optical detection device 100 of FIG. 120 is a schematic diagram of the storage box 110, FIG. 2B shows a schematic view of the telescopic arm 120 of FIG. 2A extending relative to the storage box 110, FIG. 2C shows a bottom view of the photomask 130 of FIG. 2A, and 2D is a plan view of the first conductive portion 112 and the second conductive portion 122 of FIG. 2A.

As shown in FIG. 1, the optical detection device 100 is applied to the display device 10. The display device 10 has a display panel 11 and a first electrical connection port 12. The first electrical connection port 12 is disposed on the side of the display panel 11. The optical detection device 100 can detect or detect the color information of the image displayed on the display panel 11. When the optical detection device 100 is mounted on the display device 10, the first electrical port 12 is electrically coupled with the second electrical port 111 of the optical detection device 100, so that the detection signal of the optical detection device 100 can pass through The first electrical port 12 and the second electrical port 111 are transmitted to a controller (not shown) electrically coupled to the first electrical port 12. In addition, one of the first electrical connection port 12 and the second electrical connection port 111 is, for example, a flexible conductive post, such as a pogo pin, and the other is, for example, a mating connector.

As shown in FIG. 2A, the optical detection device 100 includes a collapsible box 110, a telescopic arm 120 and a reticle 130. The folding box 110 includes the aforementioned second electrical connection port 111 and the first conductive portion 112. The first conductive portion 112 is electrically coupled to the second electrical connection port 111. The telescopic arm 120 is slidably arranged in the storage box 110. The telescopic arm 120 includes an optical sensor 121 and a second conductive portion 122, wherein the second conductive portion 122 is electrically connected to the optical sensor 121. When the second electrical port 111 is electrically coupled to the first electrical port 12 and the telescopic arm 120 slides at several different positions relative to the storage box 110, the optical sensor 121 may be located at several positions above the display panel 11 Different sensing positions, and the first conductive portion 112 remains electrically connected to the second conductive portion 122. In this way, the telescopic arm 120 is located at several different positions relative to the collapsible box 110 to receive light from different screen positions of the display panel 11 to detect the color of the screen.

The aforementioned sensing positions include at least the middle position and/or the edge position (close to the frame of the display device 10) of the display surface 11s of the display panel 11.

As shown in FIG. 2A, the storage box 110 has an accommodation space 110a, and the telescopic arm 120 is slidably arranged in the accommodation space 110a. In addition, the cross-sectional shape of the accommodating space 110a (such as the cross-sectional shape along the YZ plane) and the cross-sectional shape of the telescopic arm 120 (such as the cross-sectional shape along the YZ plane) are polygonal, such as triangular, rectangular, or other non-circular shapes. In this way, the rotation of the telescopic arm 120 about the X axis can be avoided, thereby avoiding the deviation of the first conductive portion 112 and the second conductive portion 122.

As shown in FIGS. 2A and 2B, the first conductive portion 112 includes a sliding groove 112r and a conductive layer 1121, the conductive layer 1121 is formed on the inner wall of the sliding groove 112r, and the second conductive portion 122 is, for example, a conductive pillar and is slidably located on the sliding Normal in slot 112r 地contact conductive layer 1121. In this way, regardless of the relative positions of the collapsible box 110 and the telescopic arm 120, the second conductive portion 122 and the conductive layer 1121 of the first conductive portion 112 can be electrically connected. In addition, the conductive layer 1121 is, for example, a metal layer, such as a copper layer.

As shown in FIG. 2A, the conductive layer 1121 continuously extends at two opposite ends of the corresponding sliding groove 112r, such as the opposite first end 112r1 and second end 112r2.

In addition, as shown in FIG. 2A, the sliding groove 112r may have several concave portions, such as a first concave portion 112a1 and a second concave portion 112a2, which are respectively located at the first end 112r1 and the second end 112r2 of the sliding groove 112r, that is, several concave portions Located in the relative two limit positions of the sliding stroke. In another embodiment, the recess may not be located at the first end 112r1 and/or the second end 112r2 of the sliding groove 112r, but at any position between the first end 112r1 and the second end 112r2. In another embodiment, the number of recesses of the sliding groove 112r may be one or more than two. In addition, the first conductive portion 112 is, for example, an elastic conductive post, such as a probe-type connector. When the first conductive portion 112 is located in the corresponding concave portion, the first conductive portion 112 falls into the corresponding concave portion based on the action of the elastic force (such as along the Y axis) to provide an engaging feel and can be temporarily fixed and retractable The relative position of the arm 120 and the storage box 110. Since the first conductive portion 112 has elasticity, only a slight force is needed to separate the concave portion and the first conductive portion 112, so that the telescopic arm 120 and the folding box 110 return to a slidable state.

In other embodiments, the first conductive portion 112 includes a sliding slot 112r and a plurality of contacts (not shown) separated from each other. These contacts are formed on the inner wall of the sliding slot 112r. When the optical sensor 121 is in these sensing positions relative to the collapsible box 110, the first conductive portion 112 is electrically connected to different contacts, and is electrically connected to the optical sensor 器121 and the second electrical port 111. When the optical sensor 121 is not in these sensing positions relative to the storage box 110, the first conductive portion 112 is not in contact with any contact, so the optical sensor 121 and the second electrical port 111 are electrically separated. In this example, the sliding groove 112r may also have a plurality of separate concave portions, wherein each contact is formed on the concave surface of the corresponding concave portion. When the first conductive portion 112 is located in the corresponding concave portion, the first conductive portion 112 falls into the corresponding concave portion based on the action of the elastic force, which can also provide a snap feeling similar to the aforementioned and a temporary fixing effect.

As shown in FIG. 2A, the extending direction of the sliding groove 112 r of the first conductive portion 112 is the same as the extending and contracting direction of the telescopic arm 120 relative to the storage box 110. For example, the extending direction of the chute 112r and the extending and contracting direction of the telescopic arm 120 relative to the storage box 110 are the X-axis direction in FIG. 2A.

As shown in FIGS. 2A, 2B, and 2D, the mask 130 is disposed on the telescopic arm 120 and has an opening 130a and an end surface 130s, wherein the opening 130a is exposed from the end surface 130s. The optical sensor 121 is disposed in the photomask 130 and has a sensing surface 121s. The sensing surface 121s is exposed from the opening 130a of the photomask 130 to receive the screen light from the display panel 11.

In addition, as shown in FIGS. 2A and 2C, the end surface 130s of the reticle 130 hermetically surrounds the opening 130a, and the reticle 130 is formed of an opaque material. In this way, when the optical detection device 100 is mounted on the display device 10, as shown in FIG. 1, the amount of light leakage of the screen light entering the display panel 11 in the reticle 130 can be reduced, and even there is no light leakage, thereby improving The accuracy of the color correction of the display screen of the display panel 11 (because the amount of light leakage is small, the received light intensity increases).

In addition, as shown in FIG. 2A, the storage box 110 has an outer surface 110s, and the end surface 130s protrudes from the outer surface 110s. In this way, when the optical detection device 100 is mounted on the display device 10, as shown in FIG. 1, most or almost the entire end surface 130s is in close contact with the display surface 11s of the display panel 11 of the display device 10. In this way, the size of the gap between the end surface 130s of the photomask 130 and the display surface 11s of the display panel 11 (or even avoiding the occurrence of gaps) can be reduced, so as to reduce the amount of light leaking from the gap of the picture light emitted from the display panel 11, even without There is an amount of light leakage, thereby improving the accuracy of color correction for the display screen of the display panel 11 (because of the small amount of light leakage, the received light intensity increases).

As shown in FIG. 2D, the number of the second conductive parts 122 is four, which are a power line, a ground line, and several signal lines. The signal lines in this embodiment are two examples, but the embodiment of the present invention does not This is the limit. The number of the first conductive portions 112 is the same as that of the second conductive portions 122, wherein each first conductive portion 112 is slidably disposed on the corresponding second conductive portion 122. In another embodiment, depending on the signal requirements and/or device functions, the number of the second conductive parts 122 may be less than or more than four.

Please refer to FIGS. 3A~3E. FIGS. 3A~3D show the process of the optical detection device 200 changing from the collapsed state to the extended state according to another embodiment of the invention, and FIG. 3E shows the abutment of FIG. 3A 240 and the top view of the storage box 210.

As shown in FIG. 3A, the optical detection device 200 includes a collapsible box 210, a first conductive portion 212, a telescopic arm 220, a photomask 130 and a contact 240.

The folding box 210 includes a second electrical port 111. The first conductive portion 212 is electrically coupled to the second electrical connection port 111. The telescopic arm 220 is slidably disposed in the collapsible box 210 and includes an optical sensor 121 and a plurality of second conductive parts 222 separated from each other. These second conductive parts 222 are electrically connected to the optical sensor 121. When the second electrical connection port 111 is electrically coupled to the first electrical connection port 12 and the telescopic arm 220 slides at several different positions relative to the collapsible box 210, the optical sensor 121 is different from the several above the display panel 11 And the first conductive portion 212 is electrically connected to a different second conductive portion 222. In this way, the telescopic arm 120 can be located at several different positions relative to the collapsible box 110 to receive light from different screen positions of the display panel 11 for color detection of the screen.

The storage box 210 has an accommodation space 210a, and the telescopic arm 220 is slidably arranged in the accommodation space 210a. In addition, the cross-sectional shape of the accommodating space 210a (such as the cross-sectional shape along the YZ plane) and the cross-sectional shape of the telescopic arm 220 (such as the cross-sectional shape along the YZ plane) are polygonal, such as triangular, rectangular, or other non-circular shapes. In this way, the rotation of the telescopic arm 220 about the X axis can be avoided, thereby avoiding the deviation of the first conductive portion 212 and the second conductive portion 222. In addition, one of the first conductive portion 112 and the second conductive portion 222 is, for example, an elastic conductive post, such as a probe connector, and the other is, for example, a mating connector. In addition, the number of the first conductive portions 212 and/or the types of signals transmitted are similar to the aforementioned first conductive portions 112, and will not be repeated here. In addition, the two second conductive portions 222 shown in FIG. 3A each have the same number as the first conductive portions 212. For example, similar to the aforementioned 2D figure, the number of first conductive portions 212 is, for example, There are four, and the number of the second conductive portions 222 shown in FIG. 3A is the same as the number of the first conductive portions 212.

As shown in FIG. 3A, there is a gap G1 between the storage box 210 and the telescopic arm 220. The contacting member 240 of the optical detection device 200 is partially located in the gap G1 and includes a pressing portion 241, a first extending portion 242 and a lever 243, wherein the first extending portion 242 and the lever 243 are connected to the pressing portion 241. At least two of the pressing portion 241, the first extending portion 242, and the lever 243 have an integrally formed structure, or the entire abutment 240 has an integrally formed structure.

The thickness T1 of the pressing portion 241 is substantially equal to the width of the gap G1. As such, when the pressing portion 241 is pushed into the gap G1, as shown in FIG. 3A, the pressing portion 241 tightly fits in the gap G1 to press the telescopic arm 220 against the inner side wall of the storage space 210a of the storage box 210 On 210w, the relative position of the telescopic arm 220 and the storage box 210 is temporarily fixed.

In addition, as shown in FIG. 3A, the first conductive portion 212 is disposed in the contact 240 to interlock with the contact 240. In addition, the first conductive portion 212 is exposed from the outer surface of the contact 240 to electrically contact the second conductive portion 222. When the optical sensor 121 is in these sensing positions relative to the collapsible box 210, the pressing portion 241 of the abutting member 240 is tightly fitted in the gap G1 and the first conductive portion 212 provided in the abutting member 240 is in electrical contact Corresponding to the second conductive portion 222. For example, as shown in FIG. 3A, when the optical sensor 121 is in one of several sensing positions relative to the collapsible box 210, the pressing portion 241 is located in the gap G1 and the first conductive portion 212 electrically contacts the second One of the conductive parts 222 allows the optical sensor 121 to pass through the first conductive part 212 and the second conductive The portion 222 is electrically coupled to the second electrical connection port 111. As shown in FIG. 3B, when the optical sensor 121 is located at another one of several sensing positions relative to the collapsible box 210, the pressing portion 241 is located in the gap G1 and the first conductive portion 212 electrically contacts the two second conductive The other part 222 makes the optical sensor 121 electrically coupled to the second electrical connection port 111 through the first conductive part 212 and the second conductive part 222.

As shown in FIG. 3B, the abutment 240 can be pushed back to disengage the pressing portion 241 from the gap G1 to release the telescopic arm 220 (releasing the fixed relationship between the collapsible box 210 and the telescopic arm 220). Since the pressing portion 241 releases the telescopic arm 220, the telescopic arm 220 and the storage box 210 can slide relatively. In addition, when the pressing portion 241 is separated from the gap G1, the first conductive portion 212 and the second conductive portion 222 are separated (electrically separated).

In addition, as shown in FIGS. 3A and 3B, the first extending portion 242 of the abutment 240 is connected to the pressing portion 241. In addition, the contact member 240 is an insulating contact member. In terms of material, the contact member 240 can be made of plastic. The height H1 of the first extending portion 242 gradually decreases from the pressing portion 241 to the free end 2421 of the first extending portion 242. Due to the tapered design of the first extending portion 242, when the pressing portion 241 is separated from the gap G1, as shown in FIG. 3B, the first extending portion 242 is loosely fitted in the gap G1 without interfering with the telescopic arm 220 . In this way, in addition to preventing the abutment 240 from being separated from the collapsible box 210, the collapsible box 210 and the telescopic arm 220 can also be kept in a freely slidable state.

As shown in FIGS. 3A and 3E, the storage box 210 has an opening 210r. The lever 243 of the abutting member 240 is connected to the pressing portion 241 and protrudes from the opening 210r to facilitate manual operation by the user. The length L1 of the opening 210r is greater than the outer diameter d of the lever 243, so that the lever 243 can slide along the length extension direction of the opening 210r, to select The relative positions of the telescopic arm 220 and the storage box 210 are selectively fixed or the fixed relationship between the telescopic arm 220 and the storage box 210 is released. As shown in FIG. 3E, the length L2 of the abutting member 240 along the extending direction of the opening 210r is greater than the length L1 of the opening 210r along the extending direction. In this way, the abutting member 240 and the collapsible box 210 can be easily separated.

As shown in FIG. 3C, since the abutment 240 releases the telescopic arm 220, the telescopic arm 220 can slide relative to the collapsible box 210 to adjust the relative position of the optical sensor 121 and the collapsible box 210. When determining the relative position of the optical sensor 121 and the storage box 210, for example, the position of the first conductive portion 212 corresponds to one of the second conductive portions 212, as shown in FIG. 3D, the abutment member 240 can be pushed to make the abutment The pressing portion 241 of the member 240 moves into the gap G1 until the pressing portion 241 tightly fits in the gap G1. After the pressing portion 241 tightly fits in the gap G1, as described above, the contacting member 240 presses the telescopic arm 220 in the collapsible box 210 and the first conductive portion 212 provided in the contacting member 240 electrically contacts the corresponding Second conductive portion 222.

Please refer to FIGS. 4A-4B, FIG. 4A shows a schematic diagram of the telescopic arm 320 of the optical detection device 300 according to another embodiment of the present invention, which is located in the folding box 310, and FIG. 4B illustrates the telescopic arm of FIG. 4A A schematic diagram of 320 extending relative to the folding box 310.

As shown in FIG. 4A, the optical detection device 300 includes a collapsible box 310, a telescopic arm 320 and a reticle 130. The folding box 310 includes a second electrical connection port 111, a first conductive portion 212, a box 313, and a magnetic element 314. The first conductive portion 212 is electrically coupled to the second electrical connection port 111. The telescopic arm 320 is slidably arranged in the collapsible box 310 and includes an optical sensor 121 and several second conductive parts separated from each other 222, the second conductive portions 222 are electrically connected to the optical sensor 121. When the second electrical port 111 is electrically coupled to the first electrical port 12 and the telescopic arm 220 slides relative to the collapsible box 210, the optical sensor 121 is relative to several different sensing positions above the display panel 11, and The first conductive portion 212 is electrically connected to different second conductive portions 222. In this way, the telescopic arm 120 can be located at several different positions relative to the collapsible box 110 to receive light from different screen positions of the display panel 11 for color detection of the screen.

The storage box 310 has an accommodation space 310a, and the telescopic arm 320 is slidably arranged in the accommodation space 310a. The cross-sectional shape of the accommodating space 310a (such as the cross-sectional shape along the YZ plane) and the cross-sectional shape of the telescopic arm 320 (such as the cross-sectional shape along the YZ plane) are polygonal, such as triangular, rectangular, or other non-circular shapes. In this way, the rotation of the telescopic arm 320 about the X axis can be avoided, thereby avoiding the deviation of the first conductive portion 212 and the second conductive portion 222.

As shown in FIG. 4A, the magnetic element 314 is disposed in the box 313 and the position of the magnetic element 314 corresponds to one of the first conductive portions 212. Each second conductive portion 222 is a magnetic conductive portion, and is closer to the telescopic arm 320 than the magnetic element 314. In this way, when the position of the magnetic element 314 corresponds to the first conductive portion 212, a magnetic attraction force is generated between the magnetic element 314 and the first conductive portion 212. This magnetic attraction force drives the distance between the first conductive portion 212 and the magnetic element 314 to be shortened. The first conductive portion 212 and the second conductive portion 222 are electrically contacted, as shown in FIG. 4A. In one embodiment, the magnetic element 314 is, for example, a magnet.

Since the telescopic arm 320 and the collapsible box 310 are temporarily fixed by magnetic attraction, the temporary fixed relationship between the telescopic arm 320 and the collapsible box 310 can be released with a little force. After the fixed relationship between the telescopic arm 320 and the storage box 310 is released, the relative position of the telescopic arm 320 and the storage box 310 can be adjusted. When one of the second conductive portions 222 provided in the telescopic arm 320 is close to the position of the first conductive portion 212, as shown in FIG. 4B, a magnetic attraction force is generated between the magnetic element 314 and the first conductive portion 212 This magnetic attractive force drives the distance between the first conductive portion 212 and the magnetic element 314 to shorten, and makes the first conductive portion 212 and the second conductive portion 222 electrically contact.

In summary, although this disclosure has been disclosed as above by the embodiments, it is not intended to limit this disclosure. Those with ordinary knowledge in the technical field to which this disclosure belongs can be used for various changes and retouching without departing from the spirit and scope of this disclosure.
