Description

Multi-view display device

[0001] The embodiments relate to a multi-view display device, and more specifically, to a multi-view multi-view display device.

[0002] As the information society develops, the demand for displays is increasing in various forms. In response to this, recent displays include Liquid Crystal Displays (LCDs), Field Emission Displays (FEDs), Plasma Display Panels (PDPs), and Electroluminescence Devices.

[0003] A liquid crystal panel of a liquid crystal display includes a liquid crystal layer and a TFT substrate and a color filter substrate facing each other with the liquid crystal layer in between, and can display an image using light provided from a backlight unit.

[0004] As an example of an electroluminescence device, active matrix type organic light-emitting displays are commercially available. Since organic light-emitting displays are self-emissive devices, they do not require a backlight compared to liquid crystal multi-view displays. They are attracting attention as next-generation displays due to advantages in response speed and viewing angle.

[0005] Recently, due to the advancement of display panel manufacturing processes, the thinning and lightweighting of display panels and displays containing them are actively being pursued. In addition, by enabling displays to have a wider variety of shapes, such as flexible displays or curved displays, not only technical aspects but also design aspects are being emphasized.

[0006] In particular, interest in so-called multi-view displays, which provide various views using a single multi-view orientation display, has been growing recently.

[0007] A multiview image represents a scene containing different views. The views can overlap to varying degrees depending on the viewing angle. Viewers can perceive the different views of the multiview image simultaneously presented on the display as they are positioned at different viewing angles relative to the display. For example, the different views of the multiview image are presented individually to each of the viewer's eyes to create a sense of depth. In some cases, viewers may wear special glasses to control which views are perceived by their eyes. In other cases, the views are directed to each eye in an autostereoscopic manner, without the need for special glasses. In both cases, the multiview display system renders the multiview images for display. In some cases, multiview images are generated using cameras (or multiple cameras) at different viewpoints to capture the scene. Each view is combined to form the multiview image.

[0008]

[0009] The technical problem of the embodiments of the present invention is to provide a multi-view directional display capable of providing various views by varying the angles between LEDs within a single LED assembly.

[0010] In addition, the embodiments of the present invention have the technical objective of providing a multi-view direction display capable of simultaneously adjusting the angles of a plurality of LED assemblies by adjusting a single connection link.

[0040]

[0041] FIGS. 1 and FIGS. 2 are drawings showing a multi-view direction display (1000) according to embodiments. FIGS. 3 is a drawing showing a state in which the rear case (200) is removed from the multi-view direction display (1000) according to embodiments.

[0042] Referring to FIGS. 1 to 3, a multi-view direction display (1000) according to embodiments may include an LED assembly (100), a rear case (200), a connecting bar (300), a connecting link (400), etc.

[0043] The multi-view direction display (1000) according to the embodiments may correspond to an LED that does not use a backlight unit because the elements forming the pixels each emit light on their own. That is, the plurality of LEDs (120, see FIG. 5) of the multi-view direction display (1000) according to the embodiments may provide a view to the user, with each LED responsible for one pixel.

[0044] An LED assembly (100) may include a plurality of LEDs (120) that provide a view to a user. More specifically, a plurality of LEDs (120) may be spaced apart from each other in a first direction and arranged on the LED assembly (100), and a plurality of LED assemblies (100) may be arranged in a second direction perpendicular to the first direction.

[0045] Multiple LEDs (120) can be distinguished into sets according to the view provided. That is, for example, multiple LEDs (120) may include a first LED set (121, see FIG. 5) providing a first view, a second LED set (122, see FIG. 5) providing a second view, and a third LED set (123, see FIG. 5) providing a third view. The first LED set (121), the second LED set (122), and the third LED set (123) may all include multiple LEDs.

[0046] That is, the multi-view direction display (1000) according to the embodiments may correspond to a multiview multi-view direction display that provides multiple views on a single display, allowing the user to view different images from different angles. The principle of the multi-view direction display (1000) according to the embodiments providing multiple views on a single display will be explained in detail in FIGS. 5 to 8.

[0047] The rear case (200) is a case located at the rear of the LED assembly (100), and a connecting bar (300), a connecting link (400), etc. can be placed inside.

[0048] The connecting bar (300) can be mounted on the rear of the LED assembly (100) and can be combined with both the rear case (200) and the connecting link (400). More specifically, the connecting bar (300) can be rotatably combined with the rear case (200). That is, the connecting bar (300) can be combined with the rear case (200) so that movement is fixed but rotation is possible. For example, the connecting bar (300) can be combined with the rear case (200) by a shoulder bolt (301).

[0049] The connecting link (400) can be joined by a plurality of connecting bars (300) and a shaft (302). That is, a plurality of connecting bars (300) formed on each of the plurality of LED assemblies (100) can be joined to a single connecting link (400). The connecting link (400) can be formed by extending in a second direction. That is, the connecting link (400) can be formed by extending in a direction perpendicular to the LED assembly (100).

[0050] The connecting link (400) may include a connecting link (410) to which the shaft (302) is connected, and a protruding link (420) formed by protruding in a rearward direction from the connecting link (410). That is, the connecting link (400) may be formed in a 'T' shape.

[0051] The connecting link (400) can move in an up-and-down direction. For example, the connecting link (400) can be moved in an up-and-down direction by an external force applied by a user. When the connecting link (400) moves in an upward direction or a downward direction, the plurality of LED assemblies (100) connected to the connecting link (400) can rotate simultaneously due to the movement of the connecting link (400).

[0052] Accordingly, the multi-view direction display (1000) according to the embodiments has the effect of being able to adjust the angles of multiple LED assemblies (100) at once by utilizing the up-and-down movement of a single connecting link (400).

[0053] FIG. 4 is a drawing showing an LED assembly (100) of a multi-view direction display (1000) according to embodiments. FIG. 5 is a drawing showing a cross-section in the AA' direction of FIG. 4.

[0054] As described in FIGS. 1 to 3, the LED assembly (100) may include a plurality of LED chips (120), and the plurality of LEDs (120) may be distinguished into sets according to the provided view. Referring to FIG. 4, the plurality of LEDs (120) may include a first LED set (121), a second LED set (122), and a third LED set (123). However, FIG. 5 is merely an example, and the plurality of LEDs (120) may be composed of more sets or fewer sets.

[0055] The first LED chips (121) may be formed on the LED assembly (100) to form a specific angle with respect to the second LED chips (122). More specifically, the first LED set (121) and the third LED set (123) may be formed on the LED assembly (100) to each form a specific angle with respect to the second LED set (122). That is, the first LED set (121) and the third LED set (123) may be formed symmetrically with respect to the second LED set (122). The specific angle may have various angles, for example, the specific angle may be between 15 and 50 degrees.

[0056] The LED assembly (100) may include a support member (110). The support member (110) may have first pixels composed of a first LED set (121) that displays a first image in a first direction, second pixels composed of a second LED set (122) that displays a second image in a second direction, and third pixels composed of a third LED set (123) that displays a third image in a third direction formed therein.

[0057] More specifically, the support member (110) may include a first mounting portion (111) on which the first LED set (121) is mounted, a second mounting portion (112) on which the second LED set (122) is mounted, and a third mounting portion (113) on which the third LED set (123) is mounted. That is, the number of LED sets (120) and the number of mounting portions may be the same.

[0058] The first LED set (121) may be formed on the LED assembly (100) to form a step with the second LED set (122). More specifically, the first LED set (121) and the third LED set (123) may be formed on the LED assembly (100) to each form a step with the second LED set (122). At this time, the first LED set (121) and the third LED set (123) may be formed at the same height. The step may have various heights and may have a height at which there is no overlap between the view provided by the first LED set (121) or the third LED set (123) and the view provided by the second LED set (122).

[0059] A multi-view direction display (1000) according to embodiments may further include a bar cover (140) which is coupled to an LED assembly (100) so that a plurality of LEDs (120) are positioned in an internal space and has a through-hole (141) formed at the top. More specifically, the bar cover (140) may be coupled to an LED assembly (100) so that a first LED set (121), a second LED set (122), and a third LED set (123) are positioned in an internal space.

[0060] The first LED set (121), the second LED set (122), and the third LED set (123) can provide light through a through-hole (141) formed in the bar cover (140), and consequently provide a view (image) to the user. The bar cover (140) may be made of a material that blocks light, and consequently, light may be provided to the user through the through-hole (141) formed in the bar cover (140). The through-hole (141) may be formed in the center of the upper part. The bar cover (140) may be formed as an extension, similar to the LED assembly (100).

[0061] The size of the through-hole (141) may be determined according to a specific location for providing a view (image) to the user. Alternatively, the size of the through-hole (141) may be determined such that there is no overlap between the view provided by the first LED set (121) or the third LED set (123) and the view provided by the second LED set (122). For example, the through-hole (141) may be formed in the shape of a slit or a hole.

[0062] Additionally, in the multi-view display device (1000) according to the embodiments, only the first LED chips (121) are shown through the through-hole (141) in the first direction, only the second LED chips (122) are shown through the through-hole (141) in the second direction, and only the third LED chips (123) are shown through the through-hole (141) in the third direction.

[0063] As illustrated in FIG. 5, the second seating portion (112) may be formed as a first surface at a position facing perpendicularly to the penetration portion (141), the first seating portion (111) may be formed as a second inclined surface having a predetermined angle on the first side of the second seating portion (112), and the third seating portion (113) may be formed as a third inclined surface having a predetermined angle on the second side of the second seating portion (112). The first seating portion (111) and the third seating portion (113) may be formed symmetrically with respect to the second seating portion (112).

[0064] The depth at which the second mounting portion (112) is formed may be longer than the height of the second LED chips (122). That is, the length from the first surface of the second mounting portion (112) to the second surface of the first mounting portion (111) may be longer than the height of the second LED chips (122). Alternatively, the length from the first surface of the second mounting portion (112) to the third surface of the third mounting portion (113) may be longer than the height of the second LED chips (122).
