Referring to FIG. 1, FIG. 1 is a schematic diagram of a display system according to an embodiment of the invention. In the embodiment, the display system 100 includes an image receiving distributer 110, a display device 120, a sensor 130 and a host 140. The image receiving distributer 110 is configured to receive an image signal IMGS corresponding to a single frame F, and the image signal IMGS is segmented into a plurality of sub-image signals IMGS_1-IMGS_4. The sub-image signals IMGS_1-IMGS_4 correspond to a plurality of different blocks S1-S4 of the frame F respectively. For example, the sub-image signal IMGS_1 corresponds to the block S1 in the frame F, the sub-image signal IMGS_2 corresponds to the block S2 in the frame F, the sub-image signal IMGS_3 corresponds to the block S3 in the frame F, and the sub-image signal IMGS_4 corresponds to the block S4 in the frame F. In some embodiments, the image receiving distributer 110 may include an image receiver and an image distributor (not shown), where the image receiver and the image distributor may be devices independent to each other, and may be integrated into one device, which is not limited by the invention. The image receiver is configured to receive the image signal IMGS and convert a signal format of the image signal IMGS, so that the image signal IMGS may be applied to display interfaces such as a Digital Visual Interface (DVI), a High Definition Multimedia Interface (HDMI), etc. The image distributor is configured to segment the image signal IMGS to generate the sub-image signals IMGS_1-IMGS_4. Moreover, the plurality of blocks S1-S4 of the frame F corresponding to the sub-image signals IMGS_1-IMGS_4 may have partially overlapped image content, or may have no overlapped image content at all. In the embodiment, the display device 120 is coupled to the image receiving distributor 110, and is configured to receive the sub-image signals IMGS_1-IMGS_4 distributed by the image receiving distributor 110. The display device 120 includes image processors 122_1-122_4 and display panels 124_1-124_4. The image processor 122_1 is configured to receive the sub-image signal IMGS_1, and the image processor 122_1 performs image processing on the corresponding sub-image signal IMGS_1 to generate a processed sub-image signal IMGS_1′. The image processor 122_2 is configured to receive the sub-image signal IMGS 2, and performs image processing on the sub-image signal IMGS_2 to generate a processed sub-image signal IMGS 2′. The image processor 122_3 is configured to receive the sub-image signal IMGS_3, and performs image processing on the sub-image signal IMGS_3 to generate a processed sub-image signal IMGS_3′. Similarly, the image processor 122_4 is configured to receive the sub-image signal IMGS_4, and performs image processing on the sub-image signal IMGS_4 to generate a processed sub-image signal IMGS_4′. In the embodiment, the image processing includes at least one of displacement processing, rotation processing, geometric processing of a display range and warping processing. The processed sub-image signals IMGS_1′-IMGS_4′ respectively correspond to a plurality of portions P1-P4 of the frame F, and the blocks S1-S4 of the frame F corresponding to the sub-image signals IMGS_1-IMGS_4 form the portions P1-P4 of the frame F after the image processing.

The display panel 124_1 is coupled to the image processor 122_1. The display panel 124_1 receives the processed sub-image signal IMGS_1′ and displays the corresponding portion P1 of the frame F according to a position relationship between the display panels 124_1-124_4. The display panel 124_2 is coupled to the image processor 122_2. The display panel 124_2 receives the processed sub-image signal IMGS 2′ and displays the corresponding portion P2 of the frame F according to the position relationship between the display panels 124_1-124_4. The display panel 124_3 is coupled to the image processor 122_3. The display panel 124_3 receives the processed sub-image signal IMGS_3′ and displays the corresponding portion P3 of the frame F according to the position relationship between the display panels 124_1-124_4. The display panel 124_4 is coupled to the image processor 122_4. Similarly, the display panel 124_4 receives the processed sub-image signal IMGS_4′ and displays the corresponding portion P4 of the frame F according to the position relationship between the display panels 124_1-124_4. Therefore, the portions P1-P4 of the frame F corresponding to the processed sub-image signals IMGS_1′-IMGS_4′ may respectively correspond to positions of the display panels 124_1-124_4 on the display device 120. For example, the portion P1 of the frame F corresponding to the processed sub-image signal IMGS_1′ may correspond to a position of the display panel 124_1 on the display device 120. The portion P2 of the frame F corresponding to the processed sub-image signal IMGS 2′ may correspond to a position of the display panel 124_2 on the display device 120. The portion P3 of the frame F corresponding to the processed sub-image signal IMGS_3′ may correspond to a position of the display panel 124_3 on the display device 120. Similarly, the portion P4 of the frame F corresponding to the processed sub-image signal IMGS_4′ may correspond to a position of the display panel 124_4 on the display device 120.

It should be noted that the display system 100 may automatically adjust to obtain a better image-splicing display effect according to an assembling mode of the display panels 124_1-124_4 without a manual setting to adjust the image splicing. In this way, the display system 100 may implement the image-splicing display effect in response to arbitrary assembling mode of the display panels 124_1-124_4.

The display panels 124_1-124_4 of the embodiment may be display panels capable of providing a display function such as Liquid Crystal Display (LCD) display panels, Light-Emitting Diodes (LED), Organic Light-Emitting Diode (OLED) display panels, etc. The LED display panel may achieve a borderless display effect more easily than other types of displays. Therefore, the multiple LED display panels may further achieve a seamless image-splicing display effect. For simplicity's sake, the number of the image processors and the number of the display panels in the embodiment are respectively 4. The number of the image processors and the number of the display panels of the invention may be the same number greater than 1, which is not limited by the invention.

In the embodiment, the sensor 130 is configured to provide position information PI generated according to the position relationship of the display panels 124_1-124_4. The host 140 is coupled to the sensor 130 and the image receiving distributor 110. The host 140 is configured to receive the position information PI coming from the sensor 130, and generates display range positioning information DRPI according to the position information PI. The image receiving distributor 110 segments the image signal IMGS according to the received display range positioning information DRPI. The image processors 122_1-124_4 respectively perform the image processing on the sub-image signal IMGS_1-IMGS_4 according to the display range positioning information DRPI, so as to generate the processed sub-image signals IMGS_1′-IMGS_4′.

A display method of the display system is described below. Referring to FIG. 1 and FIG. 2, FIG. 2 is a flowchart illustrating a display method according to an embodiment of the invention. In the embodiment, in a step S210, the processor 130 provides the position information PI generated according to the position relationship between the display panels 124_1-124_4. In the embodiment, the display panels 124_1-124_4 and the image processors 122_1-122_4 are detachably assembled into the display device 120. Therefore, the assembling of the display panels 124_1-124_4 may be adjusted according to a usage requirement. For example, the assembling of the display panels 124_1-124_4 may be adjusted by means of at least one of displacement and rotation. The sensor 130 may provide the position information PI generated according to the position relationship between the display panels 124_1-124_4 after the display panels 124_1-124_4 are assembled.

In a step S220, the host 140 receives position information PI generated by the sensor 130, and generates the display range positioning information DRPI according to the position information PI. In the embodiment, the host 140 may calculate the relative position relationship between the display panels 124_1-124_4 and a corresponding display range according to the position information PI, so as to generate the display range positioning information DRPI. The display range positioning information DRPI determines a range of the frame F corresponding to the image signal IMGS received by the image receiving distributor 110. The display range positioning information DRPI includes shapes of the display panels 124_1-124_4 and distances and angles between the display panels 124_1-124_4. Namely, the shapes of the display panels 124_1-124_4 and the distances and angles between the display panels 124_1-124_4 determine the range of the frame F corresponding to the image signal IMGS received by the image receiving distributor 110.

In a step S230, the image receiving distributer 110 receives the image signal IMGS, and the image signal IMGS is segmented by the image receiving distributer 110 according to the display range positioning information DRPI, so as to generate the sub-image signals IMGS_1-IMGS_4. The image signal IMGS may be outputted from the host 140 or other image sources (not shown), which is not limited by the invention. In detail, the display range positioning information DRPI generated by the host 140 includes display ranges of each of the display panels 124_1-124_4 corresponding to the frame F and reference center points R1-R4 of each of the display panels 124_1-124_4 in the corresponding display ranges. The image receiving distributor 110 segments the image signal IMGS according to the display range positioning information DRPI, i.e., to generate the sub-image signals IMGS_1-IMGS_4 corresponding to the plurality of blocks S1-S4 of the frame F while taking the reference center points R1-R4 as centers.

In a step S240, the display device 120 receives the sub-image signal IMGS_1 through the image processor 122_1, receives the sub-image signal IMGS_2 through the image processor 122_2, receives the sub-image signal IMGS_3 through the image processor 122_3, and receives the sub-image signal IMGS_4 through the image processor 122_4. According to the display range positioning information DRPI, each of the image processors 122_1-122_4 of the display device 120 performs the image processing on the sub-image signal IMGS_1 to generate the processed sub-image signal IMGS_1′, performs the image processing on the sub-image signal IMGS_2 to generate the processed sub-image signal IMGS 2′, performs the image processing on the sub-image signal IMGS_3 to generate the processed sub-image signal IMGS_3′, and performs the image processing on the sub-image signal IMGS_4 to generate the processed sub-image signal IMGS_4′. In the embodiment, the image receiving distributor 110 receives the image signal IMGS and the display range positioning information DRPI, and transmits the segmented sub-image signals IMGS_1-IMGS_4 and the display range positioning information DRPI to the display device 120 all together, so that each of the image processors 122_1-122_4 performs at least one of displacement processing, rotation processing, geometric processing of a display range and warping processing on the corresponding sub-image signals IMGS_1-IMGS_4 according to the display range positioning information DRPI. The processed sub-image signals IMGS_1′-IMGS_4′ generated by the image processors 122_1-122_4 respectively correspond to the portions P1-P4 of the frame F, and the plurality of portions P1-P4 are, for example, obtained by performing the aforementioned image processing on the plurality of blocks S1-S4 of the frame F. As shown in FIG. 1, the image processor 122_1 performs geometric processing of a display range on the sub-image signal IMGS_1 according to the display range positioning information DRPI, i.e. to perform further range cutting on the block S of the frame F to generate the corresponding portion P1 of the frame F, and the image processors 122_2-122_4 perform the similar operation.

Then, in a step S250, the display device 120 receives the processed sub-image signal IMGS_1′ through the display panel 124_1, such that the display panel 124_1 may display the corresponding portion P1 of the frame F according to the position relationship between the display panels 124_1-124_4; receives the processed sub-image signal IMGS 2′ through the display panel 124_2, such that the display panel 124_2 may display the corresponding portion P2 of the frame F according to the position relationship between the display panels 124_1-124_4; receives the processed sub-image signal IMGS_3′ through the display panel 124_3, such that the display panel 124_3 may display the corresponding portion P3 of the frame F according to the position relationship between the display panels 124_1-124_4; and receives the processed sub-image signal IMGS_4′ through the display panel 124_4, such that the display panel 124_4 may display the corresponding portion P4 of the frame F according to the position relationship between the display panels 124_1-124_4.

Further, an implementation detail of the step S210 may be different according to a type of the sensor 130. Referring to FIG. 1 and FIG. 3, FIG. 3 is a flowchart illustrating a display method according to another embodiment of the invention. In the embodiment, the sensor 130 is, for example, an image sensor configured to capture images of the display device 120. The sensor 130 may be disposed at external of the display device 120. In the embodiment, the sensor 130 may capture images of the display panels 124_1-124_4 to obtain the position relationship between the display panels. In detail, in the display method of the embodiment, a step S310 may be compared with the step S210 of FIG. 2. The step S310 further includes steps S312, S314 and S316. First, in the step S312, the display panels 124_1-124_4 provide predetermined images with test patterns. The predetermined images may be regarded as test templates at the beginning of the display method of the embodiment. The predetermined images may be, for example, at least one color image different from a background color, or the predetermined image may be, for example, images of different colors presented by each of the display panels. In the step S314, the sensor 130 captures the predetermined images displayed by the display panels 124_1-124_4 to obtain at least one positioning point of the display panel 124_1, at least one positioning point of the display panel 124_2, at least one positioning point of the display panel 124_3, and at least one positioning point of the display panel 124_4. The positioning points may be position coordinates of edges or corners of the predetermined images captured by the sensor 130. In the step S316, the sensor 130 may obtain the position relationship of the display panels 124_1-124_4 according to the positioning points, so as to generate the position information PI of the display panels 124_1-124_4.

In the embodiment, the steps S320-S350 may be compared with the steps S220-S250 of FIG. 2. Enough instructions for implementation details of the steps S320-S350 may be learned from the embodiments of FIG. 1 and FIG. 2, which are not repeated.

In the embodiment, the sensor 130 may include a plurality of Inertial Measurement Units (IMU). In the embodiment, the IMUs are respectively disposed on the display panels 124_1-124_4. In detail, in the display method of the embodiment, a step S410 may be compared with the step S210 of FIG. 2. The step S410 may further include steps S412, S414 and S416. First, in the step S412, the plurality of IMUs may detect displacements and rotations of the corresponding display panels 124_1-124_4 at any time. The IMU includes a gyroscope and an accelerometer. In the embodiment, the gyroscopes are configured to detect rotations of the corresponding display panels 124_1-124_4. The accelerometers are configured to detect displacements of the corresponding display panels 124_1-124_4. In some embodiments, in the step S412, the display panels 124_1-124_4 respectively return to predetermined positions (for example, referential origins or mechanical origins) and respectively restore rotation angles to predetermined angles (for example, 0°) to implement initialization. Once the initialization is completed, the IMUs start to detect displacements and rotations of the corresponding display panels 124_1-124_4 during the assembling of the display panels 124_1-124_4. In the step S414, the IMUs respectively obtain the position relationship between the display panels 124_1-124_4 according to position variation amounts in displacements and rotations of the display panels 124_1-124_4. The position variation amounts include displacement distances and directions of the display panels 124_1-124_4 and rotation angels of the display panels 124_1-124_4. Then, in the step S416, the processor 130 generates the position information PI of the display panels 124_1-124_4 according to the position relationship between the display panels 124_1-124_4. In the embodiment, the steps S420-S450 may be compared with the steps S220-S250 of FIG. 2. Enough instructions for implementation details of the steps S420-S450 may be learned from the embodiments of FIG. 1 and FIG. 2 or the embodiments of FIG. 1 and FIG. 3, which are not repeated.

The sensor 130 is configured to provide the position information PI generated according to the position relationship between the display panels 124_1-124_4. The host 140 generates the display range positioning information DRPI according to the positioning information PI, where the display range positioning information DRPI includes display ranges of each of the display panels 124_1-124_4 corresponding to the frame F and reference center points R1-R4 of each of the display panels 124_1-124_4 in the corresponding display ranges. The image receiving distributor 110 segments the received image signal IMGS according to the display range positioning information DRPI, so as to generate the sub-image signals IMGS_1-IMGS_4. The sub-image signals IMGS_1-IMGS_4 respectively correspond to the blocks S1-S4 of the image (shown as a frame F1).

Then, the image processors 122_1, 122_3 and 122_4 respectively perform image processing on the sub-image signals IMGS_1, IMGS_3 and IMGS_4 (for example, a rotation processing opposite to the first rotation angle, i.e. to perform the rotation processing and geometric processing of the display range on the blocks S1, S3 and S4 of the frame F1) to generate the processed sub-image signals IMGS_1 ‘, IMGS_3’ and IMGS_4′. The image processors 122_2 performs image processing on the sub-image signal IMGS_2 (for example, a rotation processing opposite to the second rotation angle, i.e. to perform the rotation processing and geometric processing of the display range on the block S2 of the frame F1) to generate the processed sub-image signal IMGS 2′. In this way, the display panels 124_1-124_4 may respectively display the corresponding portions P1-P4 of the frame F1 according to the processed sub-image signals IMGS_1 ‘-IMGS_4’, so as to achieve an image-splicing display effect (shown as a display effect DD.

Referring to FIG. 1 and FIG. 5B, FIG. 5B is a schematic diagram of a usage situation according to another embodiment of the invention. Different to the FIG. 5A, the display panels 124_1-124_4 of the embodiment are assembled in a fan-blade mode (shown as an assembly A2). Similar to the FIG. 5A, the image receiving distributor 110 segments the received image signal IMGS according to the display range positioning information DRPI to generate the sub-image signals IMGS_1-IMGS_4. The sub-image signals IMGS_1-IMGS_4 respectively correspond to the blocks S1-S4 of the image (shown as a frame F2). Similar to the FIG. 5A, the image processors 122_1-122_4 respectively perform image processing on the sub-image signals IMGS_1-IMGS_4 to generate the processed sub-image signals IMGS_1 ‘-IMGS_4’.

In the embodiment, the display panels 124_1-124_4 are rotated by 90° and are not adjacent to each other (shown as an assembly A3). The sensor 130 provides the position information PI generated according to the position relationship between the display panels 124_1-124_4. After the host 140 generates the display range positioning information DRPI, the image receiving distributor 110 segments the received image signal IMGS according to the display range positioning information DRPI, so as to generate the sub-image signals IMGS_1-IMGS_4. The portions P1-P4 of the frame F3 corresponding to the sub-image signals IMGS_1-IMGS_4 are also not adjacent to each other.
