Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2024-0200915, filed on December 30, 2024, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure relates to display devices, and more particularly to display devices capable of displaying three-dimensional images. Background Technology

[0004] Three-dimensional image display devices display images in a three-dimensional manner by utilizing the principle that a sense of depth is generated when different image signals perceived by both eyes are combined. Techniques such as stereoscopic technology, volumetric display technology, and holographic technology are known as methods for realizing three-dimensional images.

[0005] Stereoscopic technology can be categorized into glasses-based and glasses-free types. In conventional glasses-free 3D image display methods, the barrier and slits constituting the parallax barrier are positioned in a structure aligned with the pixel alignment direction formed on the display panel. The left-eye and right-eye images output from the display panel are transmitted only through the slits to a certain range. Due to this parallax barrier structure, when the field of view (FoV) of the 3D image perceived by the viewer increases, a problem arises where the 3D horizontal resolution decreases proportionally. Summary of the Invention

[0006] The purpose of this disclosure is to provide a three-dimensional image display device that can improve the horizontal resolution of 3D while ensuring the field of view (FoV).

[0007] Another objective of this disclosure is to provide a three-dimensional image display device capable of displaying three-dimensional images naked-eye without using a barrier that blocks all colors of light.

[0008] The purpose of this disclosure is not limited to the purposes mentioned above, and other purposes not mentioned above will be clearly understood by those skilled in the art based on the following description.

[0009] According to one aspect of this disclosure, a three-dimensional image display device is provided. The three-dimensional image display device includes a display panel comprising a plurality of sub-pixels that emit light of different colors. The three-dimensional image display device also includes an optical component comprising a plurality of color slits for selectively transmitting light emitted from the plurality of sub-pixels. The plurality of color slits transmit light of different colors.

[0010] According to another aspect of this disclosure, a three-dimensional image display device is provided. The three-dimensional image display device includes a display panel, which includes a plurality of first sub-pixels emitting light of a first color, a plurality of second sub-pixels emitting light of a second color, and a plurality of third sub-pixels emitting light of a third color. The three-dimensional image display device also includes an optical component, which includes a plurality of first-color slits for transmitting light of the first color, a plurality of second-color slits for transmitting light of the second color, and a plurality of third-color slits for transmitting light of the third color. The three-dimensional image display device further includes a transmissive layer disposed between the display panel and the optical component to space the display panel and the optical component apart.

[0011] Further details of the exemplary embodiments are included in the detailed description and accompanying drawings.

[0012] According to this disclosure, a wide field of view (FoV) can be ensured while improving the three-dimensional horizontal resolution by displaying a three-dimensional image using an optical component comprising multiple color slits that transmit light of different colors.

[0013] According to this disclosure, a high-resolution three-dimensional image can be displayed by means of an optical component consisting only of multiple color slits that transmit light of different colors, without using a barrier that blocks all colors of light.

[0027] The advantages and features of this disclosure, as well as methods for achieving these advantages and features, will become clear from the exemplary embodiments described in detail below and the accompanying drawings. However, this disclosure is not limited to the exemplary embodiments disclosed herein, but will be implemented in various forms. The exemplary embodiments are provided by way of example only so that those skilled in the art can fully understand the disclosure and scope of this disclosure.

[0028] The shapes, dimensions, ratios, angles, numbers, etc., shown in the accompanying drawings to describe exemplary embodiments of this disclosure are merely examples, and this disclosure is not limited thereto. Throughout the specification, similar reference numerals generally indicate similar elements. Furthermore, in the following description of this disclosure, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of this disclosure. Terms such as “comprising,” “having,” and “consisting of” as used herein are generally intended to allow for the addition of additional components, unless these terms are used in conjunction with the term “only.” Unless otherwise expressly stated, any reference to the singular may include the plural.

[0029] Even if not explicitly stated, components are interpreted as including the normal tolerance range.

[0030] When using terms such as “on top of,” “above,” “below,” and “adjacent to” to describe the positional relationship between two parts, one or more parts may be located between the two parts, unless these terms are used with the terms “immediately adjacent” or “directly.”

[0031] When an element or layer is placed "on" another element or layer, the other layer or element can be directly inserted onto or between the other element.

[0032] Although the terms "first," "second," etc., are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from other components. Therefore, in the technical concept of this disclosure, the first component referred to below can be the second component.

[0033] Throughout the specification, similar reference numerals generally indicate similar elements.

[0034] For ease of description, the dimensions and thickness of each component shown in the accompanying drawings are illustrated, and this disclosure is not limited to the dimensions and thickness of the components shown.

[0035] In this specification, "display device" in a narrow sense can include: a display device comprising a display panel and a driver for driving the display panel, such as a liquid crystal module (LCM), an organic light-emitting module (OLED module), and a quantum dot module. Furthermore, "display device" can also include assemblies of electronic devices or assemblies (or equipment) that are complete or final products including LCMs, OLED modules, QD modules, etc., such as notebook computers, televisions or computer monitors, automotive display devices or equipment display devices including another type of vehicle, and mobile electronic devices including smartphones or tablets.

[0036] Therefore, the display device of this disclosure may include not only the display device itself in the narrow sense, such as LCM, OLED module, QD module, etc., but also application products or kits that are final consumer devices including LCM, OLED module, QD module, etc.

[0037] Furthermore, in some cases, an LCM, OLED module, or QD module configured with a display panel and driver can be narrowly defined as a "display device," and an electronic device comprising an LCM, OLED module, and QD module can be described as a "complete assembly." For example, a display device in the narrow sense includes a liquid crystal (LCD) display panel, an OLED display panel, or a quantum dot display panel, and a source PCB serving as a controller for driving the display panel. In contrast, a complete assembly can also include the concept of a complete PCB, which is a complete controller electrically connected to the source PCB to control the entire assembly.

[0038] As a display panel used in the exemplary embodiments of this disclosure, any type of display panel can be used, such as a liquid crystal display panel, an organic light-emitting diode (OLED) display panel, a quantum dot (QD) display panel, and an electroluminescent display panel. The display panel of this exemplary embodiment is not limited to a specific display panel in which the frame is bent together with the flexible substrate for the OLED display panel and the back support structure beneath it. Furthermore, the display panel used in the display device according to the exemplary embodiments of this disclosure is not limited to the shape or size of the display panel.

[0039] For example, when the display panel is an OLED display panel, the display panel may include multiple gate lines, data lines, and pixels formed at the intersection areas of the gate lines and / or data lines. Furthermore, the display panel may be configured to include an array, a light-emitting diode (LED) layer on the array, an encapsulation substrate or encapsulation layer disposed on the array to cover the LED layer, etc. The array includes thin-film transistors (TFTs), which are elements that selectively apply voltage to each pixel. The encapsulation layer can protect the TFTs, LED layer, etc., from external impacts and can inhibit the permeation of moisture or oxygen into the LED layer. Additionally, the layers formed on the array may include inorganic light-emitting layers, such as nanoscale material layers, quantum dots, etc.

[0040] Features of various embodiments of this disclosure may be attached or combined with each other in part or in whole, and may be technically interlocked and operated in various ways, and these embodiments may be performed independently or in association with each other.

[0041] In the following, a display device according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0042] Figure 1 This is a block diagram illustrating the configuration of a three-dimensional image display device according to an exemplary embodiment of the present disclosure. Figure 2 This is an exploded perspective view schematically illustrating a three-dimensional image display device according to an exemplary embodiment of the present disclosure. Figure 3This is a cross-sectional view illustrating the optical components of a three-dimensional image display device according to an exemplary embodiment of the present disclosure.

[0043] Reference Figure 1 A three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure includes a display panel 100, a gate driver 200, a data driver 300, a timing controller 400 including an image processor 600, a gamma voltage generator 500, and an optical component 700 disposed on the display panel 100. The three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure may further include a sensor module 800.

[0044] In addition, refer to Figure 2 The three-dimensional image display device 1000 may also include a transmissive layer 750, which is configured to space the display panel 100 from the optical component 700.

[0045] The 3D image display device 1000 can be connected to the host system 2000. The gate driver 200, data driver 300, timing controller 400, and gamma voltage generator 500 can be collectively referred to as display drivers. The gate driver 200 and data driver 300 can be collectively referred to as panel drivers.

[0046] The host system 2000 can be any type of terminal system, such as a computer, television system, set-top box, tablet computer, or mobile phone. The host system 2000 can map three-dimensional (3D) image signals onto a multi-view map. Depending on the pixel structure of the display panel 100 and the design of the optical components 700, the multi-view map can be configured in various ways. The host system 2000 can provide the mapped multi-view image signals, along with timing control signals, to the timing controller 400 of the three-dimensional image display device 1000. The timing control signals may include a dot clock, a data enable signal, a vertical synchronization signal, and a horizontal synchronization signal.

[0047] The sensor module 800 can sense the viewer's position to obtain viewer position information. The sensor module 800 can obtain viewer position information using a camera device, infrared sensor, etc., and can also obtain multiple viewer position information corresponding to different viewing positions. The sensor module 800 can output the obtained viewer position information to at least one of the host system 2000 and the timing controller 400.

[0048] The host system 2000 can modify the multi-view map based on viewer position information supplied from the sensor module 800. The host system 2000 can compare the viewer position information with preset position information for multiple view areas, and can determine the placement of the multi-view map based on the comparison results and the viewer position information. The host system 2000 can map 3D image signals onto the determined multi-view map, output the mapped multi-view image signals, and output the viewer position information to the timing controller 400.

[0049] In the three-dimensional image display device 1000, the display panel 100 may include sub-pixels of a multi-viewpoint group, wherein the multi-viewpoint is separated on a sub-pixel basis according to a multi-view map. The display panel 100 can display by receiving multi-view image signals about each view of the spatially separated multi-viewpoint group. Each multi-viewpoint group of the display panel 100 may include a plurality of red sub-pixels R emitting red light, a plurality of green sub-pixels G emitting green light, and a plurality of blue sub-pixels B emitting blue light.

[0050] The gate driver 200 can be controlled according to multiple gate control signals supplied from the timing controller 400, and can drive the gate lines of the display panel 100 individually. The gate driver 200 can supply a scan signal of the gate on voltage to the corresponding gate line during the driving period of each gate line, and can supply a gate off voltage to the corresponding gate line during the non-driving period of each gate line. The gate driver 200 can be embedded in the bezel area of ​​the display panel 100 in a gate-in-panel (GIP) type, but is not limited thereto. The gate driver 200 embedded in the display panel 100 can receive multiple gate control signals from the timing controller 400 via a level shifter (not shown). The level shifter (not shown) can generate multiple gate control signals by performing level shifting or logic processing on the control signals supplied from the timing controller 400, and can supply the generated gate control signals to the gate driver 200.

[0051] The data driver 300 can be controlled according to the data control signal supplied from the timing controller 400, and can convert digital data supplied from the timing controller 400 into analog data signals by using a digital-to-analog converter circuit. The data driver 300 can subdivide multiple reference gamma voltages supplied from the gamma voltage generator 500 into grayscale voltages, and can convert digital data into analog data signals by using the subdivided grayscale voltages. The data driver 300 can supply the converted data signals to the data lines of the display panel 100.

[0052] The data driver 300 can supply a reference voltage to the reference line of the display panel 100 under the control of the timing controller 400. The data driver 300 can also supply a reference voltage that is divided into a display voltage and a sensing voltage under the control of the timing controller 400.

[0053] The timing controller 400 can control the gate driver 200 and the data driver 300 using timing control signals supplied from the host system 2000 and internally stored timing setting information. The timing controller 400 can generate multiple gate control signals for controlling the drive timing of the gate driver 200 and can supply these multiple gate control signals to the gate driver 200. Similarly, the timing controller 400 can generate multiple data control signals for controlling the drive timing of the data driver 300 and can supply these multiple data control signals to the data driver 300.

[0054] The timing controller 400 can perform various image processing operations on the multi-view image signals supplied from the host system 2000, such as image quality compensation, degradation compensation and brightness compensation, to reduce power consumption, and can supply the image-processed data to the data driver 300.

[0055] The timing controller 400 may include, but is not limited to, the image processor 600. For example, the image processor 600 may be configured separately from the timing controller 400 and located at the input of the timing controller 400, and image data processed by the image processor 600 may be output to the data driver 300 through the timing controller 400.

[0056] The gamma voltage generator 500 can generate multiple reference gamma voltages with different gamma voltage levels and supply these reference gamma voltages to the data driver 300. Under the control of the timing controller 400, the gamma voltage generator 500 can generate multiple reference gamma voltages corresponding to the gamma characteristics of the 3D image display device 1000 and supply these reference gamma voltages to the data driver 300. The gamma voltage generator 500 can adjust the reference gamma voltage levels based on gamma data supplied from the timing controller 400 and output the adjusted voltages to the data driver 300. The gamma voltage generator 500 can adjust the high-potential power supply voltage (which is the maximum gamma voltage) based on peak brightness control supplied from the timing controller 400, and can adjust the multiple reference gamma voltages based on the adjusted high-potential power supply voltage and output them to the data driver 300.

[0057] The optical component 700 can be disposed on the light-emitting surface of the display panel 100, such as the front surface, and can separate the light path of the multi-view image displayed on the display panel 100. Thus, a 3D image can be provided to a viewer located in one of the multiple viewing zones.

[0058] The transmissive layer 750 can be disposed between the display panel 100 and the optical component 700 to separate the display panel 100 and the optical component 700 by a predetermined distance.

[0059] The transmissive layer 750 ensures the necessary gap for collecting light from the three-dimensional image emitted from the display panel 100 into the viewer's eyes, and can be made of, for example, a glass or plastic material with a predetermined thickness that is capable of transmitting light, but is not limited thereto. For example, the transmissive layer 750 can be made of a transparent adhesive film such as an optically clear adhesive (OCA) film. Furthermore, the transmissive layer 750 can have a planar shape corresponding to the shape of the display panel 100, but is not limited thereto. For example, the transmissive layer 750 can be a diffuser layer that diffuses light emitted from the display panel 100, and can have periodic micropatterns formed on its surface. Figure 2 The exemplary embodiment of the three-dimensional image display device 1000 shown in this disclosure includes a separate transmissive layer 750 having a predetermined thickness, but the disclosure is not limited thereto.

[0060] The optical component 700 of a three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure will be described in detail below.

[0061] Simultaneously refer to Figure 2 and Figure 3 The optical component 700 of the three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure includes: a plurality of color slits 710 that selectively transmit light emitted from a plurality of sub-pixels R, G and B of the display panel 100; and a plurality of blocking slits 720 that block all light emitted from the plurality of sub-pixels R, G and B of the display panel 100.

[0062] Reference Figure 3 The optical component 700 includes: a plurality of color slits 710 having a plurality of first color slits 710-1 that transmit light of a first color (e.g., red), a plurality of second color slits 710-2 that transmit light of a second color (e.g., blue), and a plurality of third color slits 710-3 that transmit light of a third color (e.g., green); and a plurality of blocking slits 720 that block light emitted from a plurality of sub-pixels SP_R, SP_B, and SP_G of the display panel 100.

[0063] Thus, the optical component 700 alternately provides slits for transmitting light and slits for blocking light, thereby separating the light path of the multi-view image into multiple different viewing areas.

[0064] like Figure 3 As shown, the optical component 700 may include a plurality of color slit groups, each color slit group including one of a plurality of first color slits 710-1, one of a plurality of second color slits 710-2, and one of a plurality of third color slits 710-3, said plurality of color slit groups being arranged repeatedly in one direction. For example, each of the plurality of color slits 710 may be implemented as a color filter that transmits only light of a specific color, but the present disclosure is not limited thereto.

[0065] In the optical component 700, a blocking slit 720 is disposed between multiple color slit groups. Furthermore, the blocking slit 720 is disposed between a first color slit 710-1, a second color slit 710-2, and a third color slit 710-3 included in one color slit group of the optical component 700. For example, each of the multiple blocking slits 720 can be implemented to block a black matrix of all colors of light emitted from multiple sub-pixels SP_R, SP_B, and SP_G of the display panel 100, but is not limited thereto.

[0066] For example, such as Figure 3 As shown, the blocking slit 720, the second color slit 710-2, the blocking slit 720, the third color slit 710-3, and the blocking slit 720 are sequentially arranged in one direction between the two first color slits 710-1. The blocking slit 720, the third color slit 710-3, the blocking slit 720, the first color slit 710-1, and the blocking slit 720 are sequentially arranged in one direction between the two second color slits 710-2. Furthermore, the blocking slit 720, the first color slit 710-1, the blocking slit 720, the second color slit 710-2, and the blocking slit 720 are sequentially arranged in one direction between the two third color slits 710-3. Although Figure 3 The illustration shows a plurality of color slits 710 of an optical component 700 of a three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure. These color slits 710 are arranged in a direction in a repeating order of first color slit 710-1, second color slit 710-2, and third color slit 710-3. However, the placement order of the first color slit 710-1, second color slit 710-2, and third color slit 710-3 among the plurality of color slits 710 is not limited to this. For example, at least one color slit that transmits light of different colors may be arranged between color slits that transmit light of the same color.

[0067] Therefore, in the optical component 700, between two spaced-apart color slits that transmit light of the same color, two color slits that transmit light of a different color can be provided, and a blocking slit 720 can be provided between the corresponding color slits.

[0068] Simultaneously, multiple first sub-pixels SP_R emitting light of a first color (e.g., red), multiple second sub-pixels SP_B emitting light of a second color (e.g., blue), and multiple third sub-pixels SP_G emitting light of a third color (e.g., green) can be provided on the display panel 100. Light from each of the multiple first sub-pixels SP_R, multiple second sub-pixels SP_B, and multiple third sub-pixels SP_G is transmitted through multiple first color slits 710-1, multiple second color slits 710-2, and multiple third color slits 710-3, respectively. At this time, light from two or more sub-pixels emitting the same color can be transmitted through a single color slit 710.

[0069] To allow viewers to freely view the multi-view image displayed from the display panel 100 in multiple viewing zones, sub-pixels emitting light of corresponding colors must be uniformly distributed about a plurality of first color slits 710-1, a plurality of second color slits 710-2, and a plurality of third color slits 710-3. That is, in the optical component 700, each color slit 710 must be configured such that sub-pixels emitting light of corresponding colors are uniformly matched with each color slit 710. To achieve this, in the optical component 700, a boundary line located at an equidistant distance from each of the two color slits 710 can be set between two color slits 710 that transmit light of the same color. In this case, the two color slits 710 that transmit light of the same color are spaced apart from each other, but can be the two closest color slits 710 among the plurality of color slits 710 that transmit light of the same color. The widths of the plurality of color slits 710 and the plurality of blocking slits 720 of the optical component 700 can be set such that the boundary lines are positioned such that the same number of sub-pixels or sub-pixels distributed at a predetermined ratio match each of the two color slits 710 that transmit light of the same color. (Refer to...) Figure 3Light emitted from some of the plurality of first sub-pixels SP_R passes through any one of the first color slits 710-1, and light emitted from others of the plurality of first sub-pixels SP_R passes through another first color slit 710-1. In this case, based on the first boundary line RL_R passing through the center between a second color slit 710-2 and a third color slit 710-3 disposed between the two spaced-apart first color slits 710-1, the plurality of first sub-pixels SP_R can be distributed and disposed on both sides. The first boundary line RL_R can pass through the center of the blocking slit 720 between the second color slit 710-2 and the third color slit 710-3. That is, the plurality of first sub-pixels SP_R located between the two first boundary lines RL_R disposed on both sides of a first color slit 710-1 match the corresponding first color slit 710-1.

[0070] For example, such as Figure 3 As shown, a first group of R_G1, comprising six first sub-pixels SP_R, can be positioned to the left of the first boundary line RL_R, and a second group of R_G2, comprising six other first sub-pixels SP_R, can be positioned to the right of the first boundary line RL_R. In this case, light emitted from each of the six first sub-pixels SP_R in the first group of R_G1 passes through a first color slit 710-1 positioned to the left of the first boundary line RL_R, and light emitted from each of the six first sub-pixels SP_R in the second group of R_G2 passes through another first color slit 710-1 positioned to the right of the same first boundary line RL_R. The number of first sub-pixels SP_R included in each of the first group of R_G1 and the second group of R_G2 positioned on both sides of the first boundary line RL_R can be the same, but is not limited to this. For example, the number of first sub-pixels SP_R included in each of the first group of R_G1 and the second group of R_G2 can vary among multiple first boundary lines RL_R at a predetermined ratio.

[0071] Similarly, based on a second boundary line RL_B passing through the center between a third color slit 710-3 and a first color slit 710-1, which are positioned between two spaced-apart second color slits 710-2, multiple second sub-pixels SP_B can be distributed and positioned on both sides. The second boundary line RL_B can pass through the center of the blocking slit 720 between the third color slit 710-3 and the first color slit 710-1.

[0072] Similarly, based on the third boundary line RL_G passing through the center between a first color slit 710-1 and a second color slit 710-2, which are positioned between two spaced-apart third color slits 710-3, multiple third sub-pixels SP_G can be distributed and positioned on both sides. The third boundary line RL_G can pass through the center of the blocking slit 720 between the first color slit 710-1 and the second color slit 710-2.

[0073] For example, the number of first sub-pixels SP_R included in each of the first group R_G1 and the second group R_G2 set on both sides of the first boundary line RL_R, the number of second sub-pixels SP_B included in each of the first group and the second group set on both sides of the second boundary line RL_B, and the number of third sub-pixels SP_G included in each of the first group and the second group set on both sides of the third boundary line RL_G can be the same, but are not limited to this.

[0074] Figure 4A It is the original image displayed by the optical components of a three-dimensional image display device according to an exemplary embodiment of the present disclosure. Figure 4B This is an example of a transmissive image displayed by an optical component of a three-dimensional image display device according to an exemplary embodiment of the present disclosure.

[0075] Figure 5 This is a plan view of the optical component according to the comparative embodiment. Figure 6 It is displayed by optical components according to a comparative embodiment for... Figure 4A An example of a transmission image of the original image.

[0076] Figure 4B and Figure 6 The transmitted image shown is an example of an image shown to one eye of the viewer's eyes.

[0077] Additionally, as an example, Figure 4B and Figure 6 The exemplary embodiment of the three-dimensional image display device 1000 according to this disclosure shows that the spacing of the color slits 710 of each color in the optical component 700 is designed to be the same as the spacing of the opening slits SL of the optical component according to the comparative embodiment. In this case, the spacing of the color slits 710 of each color can be the interval between two adjacent color slits 710 that transmit light of the same color, and the spacing of the opening slits SL of the optical component according to the comparative embodiment can, as the name suggests, be the interval between two adjacent opening slits SL.

[0078] For example, in Figure 6In the optical component shown according to the comparative embodiment, the spacing between the two spaced-apart slits SL (with one barrier BR inserted therebetween) can be... Figure 4B The optical component 700 shown has two first color slits 710-1 that are spaced apart from each other (with the blocking slit 720, the third color slit 710-3, the blocking slit 720, the second color slit 710-2 and the blocking slit 720 inserted therebetween) with the same spacing.

[0079] First, refer to Figure 5 In the optical component according to the comparative embodiment, multiple barriers (BR) that block all light emitted from multiple sub-pixels of the display panel and an opening slit (SL) that transmits all light emitted from multiple sub-pixels of the display panel are alternately provided.

[0080] According to the comparative embodiment, the optical component can be set in the display. Figure 4A The original image is displayed on the display panel. Light emitted from multiple sub-pixels of the display panel, corresponding to the original image, passes through the opening slit SL of the optical component, and thus... Figure 6 The transmitted image shown is presented to the viewer. For example, the opening slit SL can be an empty space formed between multiple barriers BR, or it can be an area formed by a layer of transparent material.

[0081] At the same time, with Figure 4A The light emitted from multiple sub-pixels of the display panel 100 corresponding to the original image passes through the first color slit 710-1, the second color slit 710-2, and the third color slit 710-3 of the optical component 700, and thus... Figure 4B The transmitted image shown is provided to the viewer.

[0082] Simultaneously refer to Figure 4B and Figure 6 It can be confirmed that, for the same region in the original image, the transmitted image portion EA passing through the first color slit 710-1, the second color slit 710-2, and the third color slit 710-3 of the optical component 700 exhibits at least a three-fold improvement in 3D horizontal resolution compared to the transmitted image portion EA′ passing through the opening slit SL of the optical component according to the comparative embodiment.

[0083] That is, assuming that the optical component 700 of the 3D image display device 1000 according to the exemplary embodiment of this disclosure and the optical component according to the comparative embodiment ensure the same field of view (FoV), in the case of the optical component 700, it is designed to maintain the spacing of the barriers that block light of a specific color, while allowing the transmission of light of colors other than the specific color within a barrier area. Therefore, while achieving the same field of view (FoV) as the optical component according to the comparative embodiment, the effect of improving the horizontal resolution of 3D can be obtained. In this case, the field of view (FoV) can refer to the range of viewing positions of the 3D image that a viewer can perceive when the image displayed on the display panel is displayed as a 3D image through the optical component.

[0084] Therefore, while ensuring the same field of view (FoV), the optical component 700 of the three-dimensional image display device 1000 according to the exemplary embodiment of the present disclosure can improve the 3D horizontal resolution compared to the structure in the optical component of the comparative embodiment where the barrier BR and the opening slit SL are alternately arranged.

[0085] Figure 7 This is an exploded perspective view schematically illustrating a three-dimensional image display device according to another exemplary embodiment of the present disclosure. Figure 8 This is a cross-sectional view illustrating the optical components of a three-dimensional image display device according to another exemplary embodiment of the present disclosure.

[0086] Reference Figure 7 and Figure 8 A three-dimensional image display device 1000' according to another exemplary embodiment of the present disclosure and according to Figures 1 to 4B The exemplary embodiment of the three-dimensional image display device 1000 is substantially the same as or similar to that of the other embodiment, except for the structure of the optical component 700'. Therefore, redundant descriptions will be omitted. The same reference numerals are used for the same parts, and their descriptions can be found by referring to… Figures 1 to 4B .

[0087] A three-dimensional image display device 1000' according to another exemplary embodiment of the present disclosure includes an optical component 700' having a plurality of color slits 710' that selectively transmit light emitted from a plurality of sub-pixels (R, G, and B) of a display panel 100. In the optical component 700', a plurality of color slit groups may be repeatedly arranged along one direction, each of the plurality of color slit groups including one of a plurality of first color slits 710-1', one of a plurality of second color slits 710-2', and one of a plurality of third color slits 710-3'. For example, each of the plurality of color slits 710' may be implemented as a color filter that transmits only light of a specific color, but the exemplary embodiments of the present disclosure are not limited thereto.

[0088] Unlike the optical component 700 of the three-dimensional image display device 1000 according to the foregoing exemplary embodiments of the present disclosure, the optical component 700' of another exemplary embodiment of the three-dimensional image display device 1000' according to the present disclosure includes a plurality of color slits 710' continuously arranged in one direction. That is, the optical component 700' is composed only of a plurality of color slits 710', and there are no separate blocking slits arranged between the plurality of color slits 710'.

[0089] Reference Figure 7 and Figure 8 The optical component 700' includes a plurality of color slits 710', which include a plurality of first color slits 710-1' that transmit light of a first color (e.g., red), a plurality of second color slits 710-2' that transmit light of a second color (e.g., blue), and a plurality of third color slits 710-3' that transmit light of a third color (e.g., green).

[0090] In the optical component 700', two color slits that transmit different colors of light are positioned between two spaced-apart color slits that transmit the same color of light. The different colors may be different from the same color.

[0091] For example, such as Figure 8 As shown, a second color slit 710-2' and a third color slit 710-3' are sequentially arranged in one direction between two first color slits 710-1'. A third color slit 710-3' and a first color slit 710-1' are sequentially arranged in one direction between two second color slits 710-2'. Furthermore, a first color slit 710-1' and a second color slit 710-2' are sequentially arranged in one direction between two third color slits 710-3'.

[0092] although Figure 8The diagram shows a plurality of color slits 710' of an optical component 700' arranged repeatedly in one direction in the order of a first color slit 710-1', a second color slit 710-2', and a third color slit 710-3', but the placement order is not limited to this. For example, at least one color slit that transmits light of different colors may be arranged between color slits that transmit light of the same color.

[0093] On the display panel 100, a plurality of first sub-pixels SP_R emitting light of a first color (e.g., red), a plurality of second sub-pixels SP_B emitting light of a second color (e.g., blue), and a plurality of third sub-pixels SP_G emitting light of a third color (e.g., green) can be configured. Each of the plurality of first sub-pixels SP_R, the plurality of second sub-pixels SP_B, and the plurality of third sub-pixels SP_G allows light to pass through one of a plurality of first color slits 710-1′, one of a plurality of second color slits 710-2′, and one of a plurality of third color slits 710-3′. In this case, two or more sub-pixels emitting light of the same color can allow light to pass through a single color slit 710′.

[0094] Reference Figure 8 Light emitted from some of the plurality of first sub-pixels SP_R passes through any one of the first color slits 710-1′, and light emitted from others of the plurality of first sub-pixels SP_R passes through another first color slit 710-1′. At this time, the plurality of first sub-pixels SP_R can be distributed and positioned about a first boundary line RL_R′, which is located between two of the plurality of first color slits 710-1′ that are spaced apart from each other but closest to each other. For example, a second color slit 710-2′ and a third color slit 710-3′ can be positioned between the two closest first color slits 710-1′ among the plurality of first color slits 710-1′, and the plurality of first sub-pixels SP_R can be distributed and positioned on both sides of the first boundary line RL_R′ that passes through the center between the second color slit 710-2′ and the third color slit 710-3′. The first boundary line RL_R′ can pass through the center between the second color slit 710-2′ and the third color slit 710-3′, that is, the boundary between the two color slits.

[0095] For example, such as Figure 8As shown, a first group of R_G1′ comprising three or four first sub-pixels SP_R can be positioned to the left of the first boundary line RL_R′, and a second group of R_G2′ comprising three or four other first sub-pixels SP_R can be positioned to the right of the first boundary line RL_R′. In this case, light emitted from each of the first sub-pixels SP_R in the first group of R_G1′ can pass through a first color slit 710-1′ located to the left of the first boundary line RL_R′, and light emitted from each of the first sub-pixels SP_R in the second group of R_G2′ can pass through another first color slit 710-1′ located to the right of the first boundary line RL_R′. Therefore, the number of first sub-pixels SP_R included in each of the first group of R_G1′ and the second group of R_G2′ positioned on both sides of the first boundary line RL_R′ can be the same or different. For example, the number of first sub-pixels SP_R included in each of the first group of R_G1′ and the second group of R_G2′ can vary among multiple first boundary lines RL_R′ at a predetermined ratio.

[0096] According to the above method, multiple second sub-pixels SP-B can be distributed and positioned on both sides of the second boundary line RL_B′. The second boundary line RL_B′ passes through the center between a third color slit 710-3′ and a first color slit 710-1′ positioned between two spaced-apart second color slits 710-2′. The second boundary line RL_B′ can pass through the center between the third color slit 710-3′ and the first color slit 710-1′, that is, the boundary between these two color slits.

[0097] Furthermore, in the manner described above, multiple third sub-pixels SP-G can be distributed and positioned on both sides of the third boundary line RL_G′. The third boundary line RL_G′ passes through the center between a first color slit 710-1′ and a second color slit 710-2′ positioned between two spaced-apart third color slits 710-3′. The third boundary line RL_G′ can also pass through the center between the first color slit 710-1′ and the second color slit 710-2′, that is, the boundary between these two color slits.

[0098] The number of first sub-pixels SP-R included in each of the first group R_G1′ and the second group R_G2′ on both sides of the first boundary line RL_R′, the number of second sub-pixels SP-B included in each of the first group and the second group on both sides of the second boundary line RL_B′, and the number of third sub-pixels SP-G included in each of the first group and the second group on both sides of the third boundary line RL_G′ can be the same as each other, but the exemplary embodiments of this disclosure are not limited thereto.

[0099] Compared with the optical component 700 of the three-dimensional image display device 1000 according to the exemplary embodiment of the present disclosure described above, the optical component 700' of the three-dimensional image display device 1000' according to another exemplary embodiment of the present disclosure can further improve the 3D horizontal resolution.

[0100] Figure 9A This is a diagram illustrating the aperture spacing of a single color in the optical components of a three-dimensional image display device according to an exemplary embodiment of the present disclosure. Figure 9B This is a diagram illustrating the aperture spacing of a single color in the optical components of a three-dimensional image display device according to another exemplary embodiment of this disclosure.

[0101] exist Figure 9A and Figure 9B In the example shown, multiple color slits 710 and 710' are illustrated with the same width. Although Figure 9A and Figure 9B The aperture spacing of a first-color slit that transmits light of a first color (e.g., red) is described, but the aperture spacing of a second-color slit and a third-color slit that transmit light of other colors (i.e., a second color (e.g., blue) and a third color (e.g., green)) can also be described in the same way.

[0102] Reference Figure 9A In the optical component 700 of the three-dimensional image display device 1000 according to an exemplary embodiment of the present disclosure, the continuously arranged blocking slit 720, the second color slit 710-2 and the third color slit 710-3 serve as blocking barriers PB_1 for light of the first color passing through the first color slit 710-1.

[0103] Reference Figure 9B In the optical component 700' of a three-dimensional image display device 1000' according to another exemplary embodiment of the present disclosure, the second color slit 710-2' and the third color slit 710-3', which are continuously provided, serve as blocking barriers PB_1 for light of the first color passing through the first color slit 710-1'.

[0104] Simultaneously refer to Figure 9A and Figure 9BThe spacing of the first color slit 710-1' in the optical component 700', which is the aperture slit used for the first color light, is smaller than the spacing of the first color slit 710-1 in the optical component 700. Furthermore, the spacing of the blocking barrier PB_1 formed by the second color slit 710-2' and the third color slit 710-3', which are the barriers used for the first color light in the optical component 700', is smaller than the spacing of the blocking barrier PB_1 formed by the blocking slits 720, the second color slit 710-2, and the third color slit 710-3, which are the barriers used for the first color light in the optical component 700.

[0105] Therefore, the optical component 700' not only significantly improves the 3D horizontal resolution compared to a structure in the optical component of a comparative embodiment where the barrier BR and aperture slit SL are alternately arranged, but also further improves the 3D horizontal resolution while ensuring the same field of view (FoV) compared to a structure in the optical component 700 where the blocking slit 720 is arranged between multiple color slits 710. Furthermore, the optical component 700' of another exemplary embodiment of the three-dimensional image display device 1000' according to this disclosure can ensure high-quality 3D horizontal resolution even when the field of view (FoV) is expanded.
