Technical Field

The present invention relates to a display device. In particular, the invention relates to a display device having a bearing seat, a display module and a color correction module.

Background

Display devices have become one of the most important and indispensable electronic devices in modern times. Accordingly, the display device can be applied to many fields, for example, word processing, drawing, design, image processing, movie playback, and the like. However, with use, the color displayed by the screen of the display device may be misaligned or attenuated for various reasons, and additional color correction may be required to maintain or improve color saturation. Accordingly, color correction devices for re-detecting the corrected screen color have been developed. Currently, most commercially available color correction devices are additionally obtained and are installed (e.g., installed, set, connected or operated) with respect to the display device. This increases the complexity and difficulty of using the color correction device by the user, and may also easily cause the problem that the color correction device is incompatible with the display device or falls off and lost. In addition, if the color correction device is built in the display module during the design of the development end, the width or thickness of the frame of the display module may be undesirably increased, which is not favorable for developing the display devices such as a light and thin screen, a frameless screen, and a high-quality appearance screen. Therefore, there is a need to develop a display device having a corresponding color correction apparatus and improving the appearance shape or configuration.

Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Various embodiments will be described hereinafter, and the spirit and principles of the invention should be readily understood by those skilled in the art with reference to the description taken in conjunction with the drawings. However, while certain specific embodiments are specifically illustrated herein, these embodiments are merely exemplary and are not to be considered in all respects as limiting or exhaustive. Therefore, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.

Referring to fig. 1 and 2, a display apparatus 10 according to an embodiment of the invention may include a carrier 100, a display module 200, and a color correction module 300. Specifically, the display device 10 may have a carrier 100 as a supporting base, and the display module 200 may be disposed on the carrier 100 and supported by the carrier 100. For example, the carrier 100 may be a base for positioning the display module 200 by being placed on a desktop or any plane installation surface, or a base for indirectly positioning the display module 200 on any wall and/or solid fixing point or installation surface. By the supporting of the supporting base 100, the display module 200 can be disposed on a desktop or any plane, or can be positioned with respect to a wall and/or a solid fixing point or a mounting surface.

The display module 200 may have a display surface 210 for displaying data such as images or graphics. In addition, the color correction module 300 may be configured to sense the color representation of the display surface 210, and the display device 10 may adjust the color representation of the display surface 210 according to the sensed result. As mentioned above, according to the present embodiment, the color correction module 300 is mounted on the carrier 100. The color correction module 300 may have a connection node 305 and a detection head 310 spaced apart from the connection node 305, where the spacing is configured to: the detecting head 310 is disposed at a distance from the connecting node 305 to ensure that the color correction module 300 rotates via the connecting node 305 to drive the position of the detecting head 310 to change relative to the display surface 210. The detecting head 310 is a sensor used by the color correction module 300 for sensing the color representation of the display surface 210, and the display device 10 can adjust and correct the color effect displayed by the display module 200 based on the result sensed by the detecting head 310. It should be noted, however, that the color correction module 300 referred to herein may be any type of color correction module 300 that is known in the art or developed in the future, without conflicting with the principles of the present invention, and that the aspects described herein are merely exemplary.

In detail, the color correction module 300 is rotatably connected to the carriage 100 through the connection node 305. Therefore, the color correction module 300 can be rotated by the connection node 305 to be in the storage state S0 shown in fig. 1 and the correction state S1 shown in fig. 2. For example, according to an embodiment of the present invention, referring to fig. 1, the susceptor 100 may have a groove 130. Accordingly, when the color correction module 300 is not needed, the color correction module 300 can be rotatably received in the groove 130 (receiving state S0). In contrast, referring to fig. 2, when the color correction module 300 needs to be used, the color correction module 300 can be rotated to stand up the color correction module 300, and the detection head 310 can be moved to face the display surface 210 (correction state S1). Therefore, the detecting head 310 can be close to or abut against the display surface 210, and can sense the color displayed on the display surface 210. Therefore, according to the display apparatus 10 of the embodiment, the color correction module 300 can be accommodated on the carrier 100 at ordinary times, and the color correction module 300 can be rotated out of the carrier 100 to make the detection head 310 face to approach or abut against the display surface 210 when necessary. Accordingly, the color correction module 300 can be disposed without occupying the space of the display module 200. For example, the frame of the display module 200 may not need to be widened or thickened to hide and store the color correction module 300 when not in use. Therefore, the exterior shape of the display apparatus 10 can be improved, and at the same time, it is not necessary to separately obtain, set, and install other color correction modules 300 not grouped with the display module 200 of the display apparatus 10.

The above-mentioned aspect of the carrier 100 for receiving the color correction module 300 is only an example. For example, according to another embodiment, the color correction module 300 can be directly disposed on the carrier 100 in the storage state S0 without being accommodated in the groove 130. However, the present invention is not limited thereto, and the structure of the carrier 100 corresponding to receiving the color correction module 300 is not limited to this specifically illustrated example.

In some embodiments, the positions of the housing, rotation, and correction of the color correction module 300 may be adjusted manually by a user. However, according to other embodiments, the positions of the color correction module 300 for receiving, rotating and correcting can be adjusted electrically.

In addition, according to the present embodiment, the color correction module 300 can be disposed on the carrier 100 in front of the display surface 210 with the extension surface 210' of the display surface 210 of the display module 200 as a reference. For example, in the storage state S0, the color correction module 300 may extend from the connection node 305 to the front of the display surface 210 in a direction away from the display module 200. Accordingly, the color correction module 300 in front of the display surface 210 can rotate from the front of the display surface 210 to the display surface 210 when correction is needed. That is, the color correction module 300 is erected relative to the installation surface by rotating, and thus the distance between the color correction module 300 and the display surface 210 is adjusted. For example, by rotating, the distance between the detector 310 of the color correction module 300 and the display surface 210 can be adjusted. In addition, in some embodiments, if the angle of the display module 200 relative to the carrier 100 may be changed, the distance between the color correction module 300 and the display surface 210 may also be adjusted by the rotation of the color correction module 300, so that the color correction module 300 (e.g., the detection head 310 of the color correction module 300) can be reliably close to or abut against the display surface 210. However, this is merely an example, for example, when the rotation of the color correction module 300 is limited, the angle of the display surface 210 relative to the installation surface of the display device 10 may be adjusted, so that the color correction module 300 (e.g., the detection head 310 of the color correction module 300) can be reliably close to or abut against the display surface 210.

If the side of the display surface 210 close to the installation surface of the carrier 100 is defined as the bottom edge, in order to make the color correction module 300 (e.g., the detecting head 310 of the color correction module 300) reliably close to or abut against the display surface 210, the color correction module 300 needs to be pivoted to be raised at least higher than the bottom edge of the display surface 210. However, the invention is not limited thereto as long as the color correction module 300 (e.g., the detector head 310 of the color correction module 300) can be reliably brought close to or abutted against the display surface 210.

As mentioned above, according to the embodiment of the present invention, the display device 10 can have the color correction module 300 built therein, and the thickening or widening of the frame of the display module 200 can be reduced or avoided. Therefore, the convenience of color correction of the display device 10 can be improved while maintaining or improving the appearance of the display module 200.

Further, according to the present invention, in order to enable the color correction module 300 to adjust the position relative to the display surface 210 more finely or flexibly, or to perform more complicated sensing and correction at more positions, or to be suitable for being accommodated in the limited accommodation space of the carriage 100, etc. (for example but not limited to these reasons), the distance between the side heads 310 and the connection nodes 305 may also be adjustable.

For example, referring to the display apparatus 20 shown in fig. 3A and 3B, according to an embodiment, the height of the color correction module 300 pivoted to the upright position can be adjusted by further multi-stage contraction. Specifically, the detector head 310 may be scalable with respect to at least a portion of the color correction module 300. For example, the color correction module 300 may include a receiving housing 320, and the detector head 310 may extend or enter the receiving housing 320 by extending or retracting (e.g., lifting) relative to the receiving housing 320. Specifically, the correction state of the display device 20 can be divided into a preliminary correction state S1 as shown in fig. 3A and a job correction state S2 as shown in fig. 3B. The color correction module 300 can rotate via the connection node 305 to rotate the housing case 320 from the original housing state to the pre-correction state S1 shown in fig. 3A. Next, referring to the operation calibration state S2 shown in fig. 3B, the detector head 310 may be extended (e.g., lifted) relative to the receiving housing 320, and thus may be sensed towards the display surface 210.

In this embodiment, the accommodating case 320 can protect the detecting head 310 when the detecting head 310 is not sensing, and the detecting head 310 is extended when the detecting head 310 needs sensing. Therefore, the present embodiment also has the effect of preventing dust, moisture, or damage to components such as the detector head 310. Further, by using the multi-stage telescopic structure, the length of the space for disposing the color correction module 300 on the carrying base 100 can be reduced, and the effect of enabling the detecting head 310 to reach a sufficient height to face the display surface 210 for sensing can be achieved. For example, if the side of the display surface 210 close to the installation surface of the carrier 100 is defined as the bottom edge, even if the receiving housing 320 is rotated and raised based on the connection node 305 to a height lower than the bottom edge of the display surface 210, the retractable structure can be used to extend the detection head 310 so that the detection head 310 can reliably reach the display surface 210, and thus can face and approach or abut against the display surface 210.

In addition, according to some embodiments, the color representation of different positions of the display surface 210 can be obtained by a multi-stage telescopic structure. For example, the length of the projection of the detecting head 310 relative to the receiving housing 320 can be adjusted to measure the color representation of the display surface 210 at different positions. Thereby, the color representation of the display surface 210 can be sensed more finely or flexibly.

In addition to the multi-stage shrinking structure, other ways of accommodating or expanding the color correction module 300 can be adopted according to other embodiments of the present invention. For example, referring to the display device 30 shown in fig. 4A to 4C, the color correction module 300 may be foldable and multi-segment structure. In detail, the color correction module 300 may have a plurality of

arms

331, 332, and the plurality of

arms

331, 332 are pivotable based on the end points of the interconnection. That is, the color correction module 300 may have an articulated folding structure. In the storage state S0 shown in fig. 4A, the plurality of

arms

331 and 332 can be pivoted to be folded and overlapped, so that the entire color correction module 300 is reduced in length and stored in the carrier 100. Then, as shown in fig. 4B, when the correction is required, the color correction module 300 can be rotated by the connection node 305 to stand from the original storage state S0 to the pre-correction state S1. Then, as shown in fig. 4C, the plurality of

arms

331 and 332 that are originally folded and overlapped are turned over and unfolded, so that the detection head 310 on the specific arm 332 can face the display surface 210 and approach or abut against the display surface 210, and the operation calibration state S2 that can perform sensing calibration is obtained.

As described above, in order to prevent the color correction module 300 from interfering with the display module 200 when rotating, and to be able to rotate and stand from the front of the display module 200 to adjust the distance between the color correction module 300 and the front surface of the display surface 210 of the display module 200 more smoothly, the color correction module 300 may be installed in a forward block of the carriage 100 relative to the display surface 210. However, the present invention is not limited thereto. For example, referring to the display apparatus 40 shown in fig. 5A and 5B, according to another embodiment of the present invention, the color correction module 300 may not be installed in a region of the carriage 100 facing forward relative to the display surface 210. For example, as shown in fig. 5A, the color correction module 300 can be installed in a block where the display module 200 is projected on the carrier 100 and extends back towards the display module 200 starting from the connection node 305. In this embodiment, referring to fig. 5B, the color correction module 300 can be rotated and erected in a short length without interfering with the display module 200. For example, the length of the color correction module 300 before being unfolded or folded and unfolded may be smaller than the distance between the bottom edge of the display surface 210 and the carrier 100. Then, similar to the embodiment described above with reference to fig. 3A and 3B, the color correction module 300 of the display device 40 may be a multi-segment shrinking structure, and the detection side head 310 is extended to approach or abut the display surface 210 toward the display surface 210 when the color correction module 300 is rotated and erected in front of the display surface 210. Therefore, the space of the carrier 100 required by the color correction module 300 in front of the display surface 210 can be reduced. Therefore, according to the present embodiment, for example, the space requirement for the front protrusion of the carriage 100 can be reduced, or the color correction module 300 can be accommodated in the central block of the less-visible carriage 100. However, the above arrangements and applications are only examples. For example, the color correction module 300 shown in fig. 5A and 5B can also be unfolded by applying the joint folding structure shown in fig. 4A to 4C, and the invention is not limited thereto.

In other embodiments of the present invention, the above-mentioned pivoting, multi-stage shrinking, and/or multi-stage folding structures can be combined in various ways, and the present invention will not be described in detail herein.

Next, referring to fig. 6, the above embodiments are substantially similar to the display device 50, wherein the virtual plane 600 through which the color correction module 300 pivots is substantially perpendicular to the display surface 210, and a projection portion of a region of the virtual plane 600 through which the color correction module 300 pivots on the display surface 210 falls within the region of the display surface 210. That is, as shown in fig. 7A, the angle θ 1 between the virtual plane 600 through which the color correction module 300 pivots and at least a portion of the display surface 210 in the above embodiments is 90 degrees. However, the present invention is not limited thereto. For example, referring to the display device 60 shown in fig. 7B, the virtual plane 600 through which the color correction module 300 disposed on the carrier 100 pivots may also be substantially parallel to the display surface 210, and the orthogonal projection portion of the area of the virtual plane 600 through which the color correction module 300 pivots on the plane of the display surface 210 falls on the area of the display surface 210. Alternatively, referring to the display device 70 shown in fig. 7C, the virtual plane 600 through which the color correction module 300 disposed on the carrier 100 pivots may substantially form an angle θ 2 with the display surface 210, and the invention is not limited thereto. It should be noted that the examples specifically shown herein are merely exemplary, and the color correction module 300 according to the present invention can move or pivot at any angle relative to the display surface 210.

When the virtual plane 600 through which the color correction module 300 pivots substantially intersects the display surface 210 (for example, when the angle θ 1 or the angle θ 2 is included), it is easier to adjust the position of the color correction module 300 correspondingly to the angle and displacement of the display module 200 (for example, the display surface 210), so that the color sensing and/or correction can be more reliably performed. In addition, when the virtual plane 600 through which the color correction module 300 pivots is substantially parallel to the display surface 210, the space occupied by the carrier 100 for installing the color correction module 300 can be reduced. As described above, the color correction module 300 and the pivoting form and mode thereof can be set according to the space for accommodating the color correction module 300 on the carrier 100, the angular direction for conveniently rotating and erecting the color correction module 300, and the angle and position variation of the display module 200 itself.

In some embodiments, as shown in fig. 8, the display device 80 may further have a structure for clipping so as to receive the color correction module 300. Specifically, in the display device 80, the groove 130 may further have a limiting member 132 therein, and the limiting member 132 is configured to clamp at least a portion of the color correction module 300 when the color correction module 300 is in the storage state S0. For example, the card secures the end of the color correction module 300 or the entire color correction module 300. Therefore, when the sensing and calibration are not performed, the color calibration module 300 can be stably accommodated on the carrier 100 without loosening or displacement.

Further, such a limiting member 132 may also be used to shield the whole or at least a part of the color correction module 300 in the storage state S0. For example, the limiting member 132 may be used to shield the detecting head 310 to prevent the detecting head 310 from being contaminated by dust, being permeated by moisture, or being damaged by external force. Therefore, the storage of the color correction module 300 can be further improved, and the lifetime of the color correction module 300 can be extended.

The above-mentioned limiting members 132 for clamping, or dust-proof, moisture-proof, damage-proof, etc. are not limited to the form or aspect specifically illustrated in fig. 8, and other embodiments according to the present invention may have other types of limiting members 132. In addition, it is also possible to eliminate the limiting member 132 for fixing, or preventing dust, moisture, damage, etc., and maintain the performance and life of the color correction module 300 by regularly maintaining or cleaning the color correction module 300.

In some embodiments, the carrier 100 and the display module 200 may have a first signal terminal and a second signal terminal, respectively, and the first signal terminal and the second signal terminal may be electrically connected to each other. Thus, the signal for controlling the color correction module 300 can be conducted through the first signal terminal and the second signal terminal, and the signal of the display module 200 can be adjusted based on the color correction module 300. For example, when the color calibration module 300 senses that the color of the display surface 210 has a deviation, it can transmit a message from the first signal terminal to the second signal terminal, and thus transmit a signal to adjust the display module 200 into the display module 200. Accordingly, the display module 200 can adjust the displayed color effect according to the signal, thereby achieving the color correction effect.

The above-mentioned way of communicating and coordinating the color calibration module 300 on the carrier 100 and the display module 200 is only an example, and the invention is not limited thereto. In addition, the carrier 100 and the display module 200 according to the present invention can also be detachable, so that they can be separated and assembled. For example, when signal connectors or interfaces for connection are provided, the corresponding first signal terminal and second signal terminal of the carrier 100 and the display module 200 can be connected to achieve electrical connection during assembly, but the invention is not limited thereto.

According to some embodiments of the present invention, since the color correction module 300 can move or rotate in a non-parallel manner with respect to the display surface 210 and move toward the display surface 210 to be close to or abut against the display surface 210, the present invention can be applied to a display device having a curved or foldable or flexible display surface 210 in addition to the above-described exemplary display device having a flat display surface 210.

In summary, according to the present invention, referring to the above exemplary embodiments, the color correction module 300 of the display device can be built in the carrier 100, and the color correction module 300 is rotated out to perform sensing correction on the display surface 210 only when the sensing correction is performed. Therefore, the display device provided by the embodiments of the invention can be built with the color correction module 300 corresponding to the display device while simplifying or improving the components and appearance of the display module 200. Therefore, the color correction module 300 can be conveniently applied, the appearance of the display module 200 is reduced or prevented from being degraded, and the risk that the color correction module 300 is not compatible with the display device or is scattered to be installed, so that the color correction module is loosened or lost is reduced or prevented.

The foregoing is only a few preferred embodiments of the invention. It should be noted that various changes and modifications can be made in the present invention without departing from the spirit and principle of the invention. It should be understood by those skilled in the art that the present invention is defined by the appended claims and various changes, substitutions, combinations, modifications and alterations can be made without departing from the scope of the invention as defined by the appended claims.
