Summary of the Invention

[0007] Personal immersive display devices according to related technologies are implemented to be worn on the face or head.

[0014] According to an embodiment of the present invention, a personal immersive display device may be provided, configured to reduce the heterogeneity between the left-eye and right-eye images caused by the offset between the display panels by such that the sampling positions of the left-eye and right-eye images are offset from the offset between the first and second display panels by such a large margin when sampling the left-eye and right-eye images in the source image.

[0015] According to an embodiment of the present invention, a personal immersive display device can be provided, configured to reduce the grid effect by configuring a first display panel and a second display panel with different resolutions such that the pixel grid of any display panel overlaps with the pixels of the other display panel in the user's field of vision and is diluted by light emitted from the overlapping pixels.

[0016] According to an embodiment of the present invention, a personal immersive display device can be provided, configured to reduce the generation of dark lines and weaken the perceptibility of dark lines at corresponding positions of the first display panel and the second display panel by configuring the first display panel and the second display panel with different pixel structures.

[0031] In the following description of examples or embodiments of the invention, reference will be made to the accompanying drawings, which illustrate specific examples or embodiments that may be implemented, and wherein the same reference numerals and symbols may be used to refer to the same or similar components, even if shown in different drawings. Furthermore, in the following description of examples or embodiments of the invention, detailed descriptions of well-known functions and components involved herein will be omitted where it is determined that such detailed descriptions would obscure the subject matter of some embodiments of the invention. Terms such as “comprising,” “having,” “including,” and “constituting” 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.” As used herein, the singular forms are intended to include the plural forms unless the context clearly indicates otherwise.

[0032] This document may use terms such as “first,” “second,” “A,” “B,” “(A),” or “(B)” to describe elements of the invention. Each of these terms is not intended to define the substance, order, sequence, or number of elements, but is merely used to distinguish the corresponding element from other elements.

[0033] When referring to the first element and the second element as "connected or joined" or "overlapping," it should be interpreted that the first element and the second element can not only be "directly connected or joined" or "directly contact or overlap," but a third element can also be "inserted" between the first element and the second element, or the first element and the second element can be "connected or joined" or "overlapping" with each other via a fourth element. Here, the second element may include at least one of two or more elements that are "connected or joined," "in contact," or "overlapping" with each other.

[0034] When using time-relative terms such as “after,” “following,” “next,” or “before,” to describe the process or operation of an element or structure, or to describe a flow or step in an operation, process, or manufacturing method, these terms may be used to describe discontinuous or non-sequential processes or operations, unless they are used in conjunction with the terms “directly” or “immediately after.”

[0035] Furthermore, when referring to any size, relative size, etc., it should be assumed that the numerical value or corresponding information of an element or feature (e.g., level, range, etc.) includes the tolerance or error range that may be caused by various factors (e.g., process factors, internal or external impacts, noise, etc.), even if no relevant description is specified. In addition, the term "may" fully encompasses all the meanings of the term "can".

[0036] In the following, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Figure 1A This is an exploded view illustrating a personal immersive display device according to an embodiment of the present invention.

[0038] Figure 1B This is a view of a display module having a first display panel and a second display panel according to an embodiment of the present invention.

[0039] Figure 1C This is a schematic block diagram of a circuit in a system according to an embodiment of the present invention.

[0040] Reference Figure 1A According to an embodiment of the present invention, the personal immersive display device 1 may include a headgear 10, a lens module 20, a display module 30, a motherboard 40, a side frame 50, and a front cover 60. The personal immersive display device may also be referred to as an immersive device 1 or an immersive wearable device 1. Here, a headgear is shown. However, any type of wearable device 10 can be used; the headgear is merely an example.

[0041] Display module 30 displays image data input from motherboard 40. The image data can be 2D / 3D image data of video images used to implement virtual reality (VR) or augmented reality (AR). Display module 30 can display various information input from motherboard 40 in the form of text or symbols.

[0042] Reference Figure 1B The display module 30 includes a first display panel 32 and a second display panel 34. The first display panel 32 can display an image visible to the left eye (e.g., a left-eye image). The second display panel 34 can display an image visible to the right eye (e.g., a right-eye image). The display module 30 may include display panel driving circuitry for driving the first display panel 32 and the second display panel 34.

[0043] In this invention, the first display panel 32 is described as a display panel for the left eye and the second display panel 34 is described as a display panel for the right eye, but the invention is not limited thereto. Conversely, the first display panel 32 may be a display panel for the right eye, and the second display panel 34 may be a display panel for the left eye.

[0044] The first display panel 32 and the second display panel 34 may be manufactured separately and disposed on the display module 30 at a selected distance from each other. In each of the first display panel 32 and the second display panel 34, a plurality of pixels PX may be arranged in a first direction (e.g., horizontal direction) and a second direction (e.g., vertical direction). The pixels PX may be configured, for example, as organic light-emitting diode (OLED) elements.

[0045] In the first display panel 32, the gaps between pixels PX are connected in a grid pattern to form pixel grid A1. In the second display panel 34, the gaps between pixels PX are connected in a grid pattern to form pixel grid A2.

[0046] Pixel grids A1 and A2 may have the following form: multiple first lines FL extending generally in a first direction (horizontal direction) and arranged along a second direction (vertical direction) overlap with multiple second lines SL extending generally in the second direction (vertical direction) and arranged transversely to the first direction (horizontal direction).

[0047] Lens module 20 includes ultra-wide-angle lenses, such as a pair of fisheye lenses for widening the user's left and right eye viewing angles. That is, a first wide-angle lens is positioned between the user's left eye and the display module, and a second wide-angle lens is positioned between the user's right eye and the display module. In other words, the pair of fisheye lenses includes a left-eye lens positioned in front of the first display panel 32 and a right-eye lens positioned in front of the second display panel 34.

[0048] Reference Figure 1CThe system includes multiple circuits. These circuits can be coupled to the headset at various locations and can also be located on the main circuit board 40 as needed. The system includes a processor 42 that runs virtual reality software and provides left-eye and right-eye images to the display module 30. The processor 42 may include an image processing unit. According to some embodiments, the processor 42 may include an image processing unit 44. In other embodiments, the processor 42 is operatively coupled to the image processing unit 44.

[0049] Image processing unit 44 can generate left-eye image data and right-eye image data by processing source image data input from the outside. Image processing unit 44 can adjust the resolution of the image data displayed on the first display panel 32 and the second display panel 34 to be suitable for the first display panel 32 and the second display panel 34 based on the depth information analysis results of the 2D image. Image processing unit 44 can downsample the source image data input from the outside to make it suitable for the resolution of the first display panel 32 and the second display panel 34.

[0050] Optionally or additionally, the image processing unit may perform geometric processing on the image by warping the positions of pixels. The image processing unit may render image data to fit the pixel structure of the first display panel 32 and the pixel structure of the second display panel 34. In some embodiments, the geometric processing function may be performed by a separate processor, such as a geometry processing unit 46 operatively coupled to the image processing unit 44. Similar to the image processing unit 44, the geometry processing unit 46 may be a processing circuit separate from the processor 42, or, according to various embodiments of the invention, may be part of and incorporated into the processor 42. The term "unit" as used herein includes circuit components that are unit parts; therefore, these units may be considered as the image processing circuit 44 and the geometry processing circuit 46.

[0051] The motherboard 40, i.e., the system, may further include an interface module 48 for connecting to external devices, a sensor module 50, etc. The interface module 48 can be connected to external devices via an interface such as Universal Serial Bus (USB) or High Definition Multimedia Interface (HDMI). The sensor module 50 may include various sensors such as gyroscopes, velocity sensors, inertial sensors, and accelerometers. The processor of the motherboard 40 can correct the left-eye and right-eye image data in response to the output signals of the sensor modules, and transmit the left-eye and right-eye image data of the input image received via the interface module to the display module 30.

[0052] The head-mounted display 10 may include a rear cover exposing a fisheye lens and a band connected to the rear cover. The rear cover, side frames 50, and front cover 60 of the head-mounted display 10 are assembled together to ensure internal space for and protect the components housing the personal immersive display device. The components include a lens module 20, a display module 30, and a mainboard 40. The band is connected to the rear cover. A user can wear the personal immersive display device on their head using their hands. When using the personal immersive display device on their head, the user views different display panels through the fisheye lens with their left and right eyes.

[0053] The side frame 50 is fixed between the headband 10 and the front cover 60 to ensure clearance within the internal space where the lens module 20, display module 30, and motherboard 40 are located. The front cover 60 is positioned on the front surface of the personal immersive display device.

[0054] The personal immersive display device according to embodiments of the present invention can be implemented as follows: Figure 1A The invention is illustrated with a head-mounted display (HMD) structure, but is not limited thereto. For example, the invention can be designed as a face-mounted display (FMD) or an eyeglasses-type display (EGD).

[0055] Figure 2 This is a view illustrating a personal immersive display device according to a first comparative example of the present invention.

[0056] Reference Figure 2 The left-eye image displayed on the first display panel 32 is transmitted to the brain via the user's left eye, and the right-eye image displayed on the second display panel 34 is transmitted to the brain via the user's right eye. In the user's brain, the left-eye and right-eye images are combined into one and recognized. Figure 2 S represents an image recognized by the user using an immersive display device, such as a user-recognized image (e.g., an image reconstructed by the user receiving images of the left and right eyes).

[0057] The first display panel 32 and the second display panel 34 are separated from each other by a first gap d1 in a first direction (horizontal direction) and are positioned at the same location in a second direction (vertical direction). Specifically, in one embodiment, the first gap d1 is the distance between the center of the first display panel 32 and the center of the second display panel 34. The distance dd between the first display panel 32 and the second display panel 34 may be less than the first gap d1. In another embodiment, the first gap d1 may be the distance between a point on the first display panel 32 and a corresponding point on the second display panel 34.

[0058] In the user's field of vision, the first display panel 32 and the second display panel 34 are matched (or overlapped or combined). Corresponding pixels in the pixels of the first display panel 32 and the second display panel 34 are matched to form the pixels of the user-recognized image S. A unit pixel of the user-recognized image S is generated by combining a pixel from the first display panel 32 and a pixel from the second display panel 34 at corresponding positions. Therefore, the user perceives the left-eye image and the right-eye image as a single image without any sense of heterogeneity.

[0059] However, since the pixel grid of the first display panel 32 and the pixel grid of the second display panel 34 are set at corresponding positions in the user's field of vision, there is a problem that the pixel grid is visible.

[0060] A fisheye lens exists between the user's eye and display panels 32 and 34, and the distance between the user's eye and display panels 32 and 34 is very short, approximately a few centimeters (cm). When the user views the image reproduced on display panels 32 and 34 through the fisheye lens, the user sees an image that is 4 to 5 times larger than the actual screen displayed on display panels 32 and 34. If the resolution of display panels 32 and 34 is low in this close-up visual application of the fisheye lens, the pixel grid is perceived as larger, reducing immersion.

[0061] Reference Figure 2 Each pixel PX has a first pixel dimension FPD in a first direction (horizontal direction when viewed in the image) and a second pixel dimension SPD in a second direction (vertical direction when viewed in the image). The size of a single pixel PX can be defined based on the first pixel dimension FPD and the second pixel dimension SPD.

[0062] Embodiments of the present invention may provide a method configured to reduce the mesh effect.

[0063] Figure 3 This is a schematic view illustrating the arrangement of a first display panel and a second display panel in a personal immersive display device according to an embodiment of the present invention; Figure 4 This is a view illustrating an example of pixel grids being offset from each other in two display panels in a personal immersive display device according to an embodiment of the present invention.

[0064] Reference Figure 3 and 4The first display panel 32 and the second display panel 34 are configured to be separated from each other by a second interval d2 in a first direction (horizontal direction). The difference between the second interval d2 and the first interval d1 is Hoff, where Hoff represents the offset distance in the horizontal direction (also known as the horizontal offset distance). The first display panel 32 and the second display panel 34 are offset from each other by Voff in a second direction (vertical direction), where Voff represents the offset distance in the vertical direction (also known as the vertical offset distance).

[0065] Figure 3 and 4 The second display panel 34 compared to Figure 2 The second display panel 34 is positioned offset along a third direction (diagonal direction), which intersects the first direction (horizontal direction) and the second direction (vertical direction). Hoff represents the component of the offset distance SH of the second display panel 34 in the first direction (horizontal direction), and Voff represents the component of the offset size SH of the second display panel 34 in the second direction (vertical direction). That is, during operation, the second display panel is offset relative to the first display panel by a horizontal offset distance Hoff and a vertical offset distance Voff. Note that the first display panel may also be offset relative to the second display panel by both horizontal and vertical offset distances. Thus, the user wearing the wearable device combines image data received from the first display panel via the first eye (e.g., the left eye) with image data received from the offset second display panel via the second eye (e.g., the right eye), thereby reducing the visibility of pixel grids A1 and A2. In other words, a technical advantage of reducing grid lines and grid perception can be achieved. Further combined... Figure 3 and Figure 4 Explain the details.

[0066] As described above, when the first display panel 32 and the second display panel 34 are as Figure 2 In the arrangement shown, the first display panel 32 and the second display panel 34 are matched with each other in the user recognition image S. Therefore, when the second display panel 34 is as shown... Figure 3 When the offset is shown, the degree to which the first display panel 32 and the second display panel 34 are offset from each other in the user recognition image S is the same as the degree of offset of the second display panel 34.

[0067] When the first display panel 32 and the second display panel 34 are offset from each other in the user's field of vision, such as Figure 4 As shown, the pixel grid A1 of the first display panel 32 and the pixel grid A2 of the second display panel 34 may be offset from each other in the user recognition image S or in the user's field of vision.

[0068] The offset direction of the pixel grid A1 of the first display panel 32 and the pixel grid A2 of the second display panel 34 is the same as the offset direction of the first display panel 32 and the second display panel 34, for example, the third direction TD (diagonal direction).

[0069] like Figure 4 As shown, in the user identification image S, the pixel grid A1 of the first display panel 32 and the pixel grid A2 of the second display panel 34 can intersect each other in an offset state, while overlapping each other only at the intersection points. In the portion other than the intersection points, the pixel grid A1 or A2 of either display panel can overlap with the pixels of other display panels.

[0070] As described above, since the pixel grid A1 or A2 of any display panel overlaps with the pixels of other display panels in the user-identified image S, the user perceives the overlapping pixel grid A1 or A2 as a composite unit with the pixels.

[0071] If the pixels of the first display panel 32 and the second display panel 34 emit light when the personal immersive display device is driven, the pixel grid A1 or A2 of either display panel is covered by light emitted from the pixels of the other display panel, thereby reducing the visibility of the pixel grid A1 and A2. In other words, the grid effect is weakened.

[0072] Because the first display panel 32 and the second display panel 34 are offset from each other, a sense of heterogeneity can be perceived between the displayed image on the first display panel 32 and the displayed image on the second display panel 34.

[0073] To reduce or minimize the appearance of heterogeneity, the offset dimension between the first display panel 32 and the second display panel 34 can be smaller than the pixel size of the display panel with the highest resolution in the first and second display panels 32 and 34. For example, it can be half the pixel size of the display panel with the highest resolution in the first and second display panels 32 and 34. The offset dimension between the first display panel 32 and the second display panel 34 can be configured to be smaller than the pixel size. In other words, Hoff can be configured to have a size smaller than the pixel size in the first direction (horizontal direction) (also called FPD), and Voff can be configured to have a size smaller than the pixel size in the second direction (vertical direction) (also called SPD). In some embodiments, both the horizontal offset distance Hoff and the vertical offset distance Voff are smaller than the first pixel size FPD or the second pixel size SPD.

[0074] Preferably, to reduce or minimize the overlapping area of ​​pixel grids A1 and A2, taking into account factors such as pixel grid width and process margin, Hoff can be configured as half the size of the pixel in the first direction (horizontal direction), and Voff can be configured as half the size of the pixel in the second direction (vertical direction). In some embodiments, both the horizontal offset distance Hoff and the vertical offset distance Voff are equal to or less than half of the first pixel size FPD or the second pixel size SPD.

[0075] In reference Figure 3 and 4 In this description, the resolution of the first display panel 32 is the same as the resolution of the second display panel 34. However, the resolution of the first display panel 32 and the resolution of the second display panel 34 may be different from each other. The first display panel 32 and the second display panel 34 may differ from each other in at least one of their resolution and pixel structure.

[0076] Considering the different resolutions of the first display panel 32 and the second display panel 34, Hoff can be configured to have a size smaller in the first direction (horizontal direction) of the pixels of the display panel with the highest resolution in the first display panel 32 and the second display panel 34, and Voff can be configured to have a size smaller in the second direction (vertical direction) of the pixels of the display panel with the highest resolution in the first display panel 32 and the second display panel 34.

[0077] In some embodiments, the horizontal offset distance Hoff or the vertical offset distance Voff between the first display panel 32 and the second display panel 34 is less than the first pixel size FPD of the display panel with the higher resolution in the first display panel 32 and the second display panel 34. Similarly, the horizontal offset distance Hoff or the vertical offset distance Voff between the first display panel 32 and the second display panel 34 is less than the second pixel size SPD of the display panel with the higher resolution in the first display panel 32 and the second display panel 34.

[0078] Preferably, Hoff can be configured as half of the first direction (horizontal direction) size of the pixels of the display panel with the highest resolution in the first display panel 32 and the second display panel 34, and Voff can be configured as half of the second direction (vertical direction) size of the pixels of the display panel with the highest resolution in the first display panel 32 and the second display panel 34.

[0079] In some embodiments, the horizontal offset distance Hoff or the vertical offset distance Voff between the first display panel 32 and the second display panel 34 is half of the first pixel size FPD of the display panel with the higher resolution between the first display panel 32 and the second display panel 34. Similarly, the horizontal offset distance Hoff or the vertical offset distance Voff between the first display panel 32 and the second display panel 34 is half of the second pixel size SPD of the display panel with the higher resolution between the first display panel 32 and the second display panel 34.

[0080] Although not shown, the first display panel 32 and the second display panel 34 may have the same pixel structure. For example, the pixel structure of the first display panel 32 and the second display panel 34 may be any one selected from RGB structure, RG-BG structure, RG-BW structure, M+ structure, etc.

[0081] As another example, the first display panel 32 and the second display panel 34 may have different pixel structures. For example, the pixel structure of the first display panel 32 may be an RGB structure, and the pixel structure of the second display panel 34 may be any one of an RG-BG structure, an RG-BW structure, and an M+ structure. See below for further details. Figures 8 to 10 Describe the RGB structure, RG-BG structure, RG-BW structure, and M+ structure.

[0082] To reduce the sense of heterogeneity felt by the user due to the offset of the display panels, image data to be displayed on each of the first display panel 32 and the second display panel 34 can be generated by using source image data with a higher resolution than the first display panel 32 and the second display panel 34 and downsampling the source image data at different locations.

[0083] Figure 5 and Figure 6 This is a view illustrating an exemplary downsampling method for a personal immersive display device according to an embodiment of the present invention.

[0084] Reference Figure 5 and 6 The source image data may have a first resolution. The first display panel 32 and the second display panel 34 may have a second resolution that is lower than the first resolution. Figure 5 and 6 An example is shown where the source image data has a resolution of 4K and the first display panel 32 and the second display panel 34 have a resolution of 2K.

[0085] To convert source image data with a first resolution of 4K to a second resolution of 2K, which is the resolution of the first display panel 32, a 2x2 filter can be used as a first mask M1. To convert source image data with a first resolution of 4K to a second resolution of 2K, which is the resolution of the second display panel 34, a 2x2 filter can be used as a second mask M2.

[0086] Figure 5 and 6 An example is shown where the resolution of the first display panel 32 is the same as that of the second display panel 34 and the first mask M1 and the second mask M2 have the same size, but this is not an exception.

[0087] The size of the first mask M1 can be determined based on the difference between the resolution of the source image data and the resolution of the first display panel 32. The size of the second mask M2 can be determined based on the difference between the resolution of the source image data and the resolution of the second display panel 34. When the resolutions of the first display panel 32 and the second display panel 34 are different from each other, the first mask M1 and the second mask M2 can have different sizes.

[0088] To reduce the perceived heterogeneity caused by the offset between display panels 32 and 34, the downsampling positions via the first mask M1 and the second mask M2 can be rendered differently. The difference between the downsampling positions via the first mask M1 and the second mask M2 can be defined as the shift offset. Figure 6 In the equation, offset_H represents the offset in the first direction (horizontal direction), and offset_V represents the offset in the second direction (vertical direction).

[0089] The magnitude and direction of the offset can be the same as the magnitude and direction of the deviation (shift) of the first display panel 32 and the second display panel 34 in the user recognition image S.

[0090] Because the reference resolution of the offset and the reference resolution of the display panel offset (shift) are different from each other, resolution conversion is required.

[0091] Since the offset represents the difference in downsampling positions in the source image data, it should be limited based on the resolution of the source image data. Simultaneously, the shift has a size defined based on the resolution of the first display panel 32 and the second display panel 34.

[0092] Since the resolution of the source image data is different from the resolution of the first display panel 32 and the second display panel 34, the offset can be calculated using the following Equation 1:

[0093] Equation 1

[0094]

[0095] For example, when the resolution of the source image data is 3840, the resolution of the first display panel 32 and the second display panel 34 is 1920, the shift is 1 / 2 pixel, and the offset is 3840 / 1920*(1 / 2), for example, 1 pixel.

[0096] Here, 1 pixel refers to a single pixel relative to the resolution of the first display panel 32 and the second display panel 34. 1 pixel refers to a single pixel relative to the resolution of the source image data. Since the source image data has a higher resolution and the first display panel 32 and the second display panel 34 have lower resolutions, the size of 1 pixel is smaller than the size of 1 pixel.

[0097] The source image data consists of multiple input pixels Pi, and the downsampled image data consists of multiple target pixels Pt. The size of a target pixel Pt is larger than the size of an input pixel Pi. One target pixel Pt corresponds to multiple associated input pixels Pi.

[0098] The data value (or gray level) of the target pixel Pt can be calculated by calculating the corresponding area ratios of multiple input pixels Pi related to the target pixel Pt, multiplying the area ratios of the relevant input pixels Pi by the corresponding data values ​​of the input pixels Pi respectively, and dividing the result by the sum of the area ratios.

[0099] Specifically, in Figure 6 In this process, the data value (0,0) in the target pixel Pt of the first display panel can be obtained by multiplying the area ratios (0,0), (0,1), (1,0) and (1,1) of the input pixel Pi, which are related to the target pixel, by 1:1:1:1, by multiplying them by the corresponding data values ​​of the input pixel Pi, summing them, and dividing the result by 4, which is the sum of the area ratios.

[0100] The data value (0,0) in the target pixel Pt of the second display panel can be obtained by multiplying the area ratios (0,0), (0,1), (0,2), (1,0), (1,1), (1,2), (3,0), (3,1), and (3,2) of the input pixel Pi, which are associated with the target pixel, by 1:2:1:2:4:2:1:2:1, respectively, with the corresponding data values ​​of the input pixel Pi, summing them, and dividing the result by 16, which is the sum of the area ratios.

[0101] In the above embodiments, the first display panel 32 and the second display panel 34 are offset so that the pixel grid A1 of the first display panel 32 and the pixel grid A2 of the second display panel 34 are offset, but the present invention is not limited thereto.

[0102] By configuring the first display panel 32 and the second display panel 34 to have different resolutions, the pixel grid A1 of the first display panel 32 and the pixel grid A2 of the second display panel 34 can be offset from each other.

[0103] Figure 7 This is a schematic view illustrating a first display panel and a second display panel in a personal immersive display device according to an embodiment of the present invention.

[0104] Reference Figure 7 The first display panel 32 and the second display panel 34 may have different resolutions.

[0105] Figure 7 An example is shown where the resolution of the second display panel 34 is higher than that of the first display panel 32. In this case, the size of the pixel grid A1 of the first display panel 32 is larger than the size of the pixel grid A2 of the second display panel 34.

[0106] Figure 7 Voff1 represents the offset dimension of pixel grid A1 of the first display panel 32 and pixel grid A2 of the second display panel 34 in the second direction (vertical direction) due to the resolution difference. Although not shown, pixel grid A1 of the first display panel 32 and pixel grid A2 of the second display panel 34 are offset from each other, and at least a portion of pixel grid A1 or A2 of either display panel overlaps with pixels of the other display panel.

[0107] Therefore, the user perceives the overlapping pixel grids A1 or A2 as a single composite unit. If the pixels of the first display panel 32 and the second display panel 34 emit light when the personal immersive display device is driven, the visibility of the pixel grids A1 or A2 of any display panel may be reduced due to the light emitted from the pixels of the other display panels, thereby weakening the grid perception.

[0108] The pixel structure of the first display panel 32 and the pixel structure of the second display panel 34 may be the same as each other. For example, the pixel structure of the first display panel 32 and the second display panel 34 may be selected from any one of the following: RGB structure, RG-BG structure, RG-BW structure, M+ structure, etc.

[0109] As another example, the pixel structure of the first display panel 32 and the pixel structure of the second display panel 34 may differ from each other. For example, the pixel structure of the first display panel 32 may be an RGB structure, and the pixel structure of the second display panel 34 may be any one of an RG-BG structure, an RG-BW structure, and an M+ structure. See below for further details. Figures 8 to 10 Describe the RGB structure, RG-BG structure, RG-BW structure, and M+ structure.

[0110] Figure 8 , 9 10 and 11 are views illustrating the pixel structure of a first display panel and a second display panel in a personal immersive display device according to an embodiment of the present invention.

[0111] Reference Figures 8 to 10 The first display panel 32 and the second display panel 34 may have different pixel structures.

[0112] Reference Figure 8 The pixel structure of the first display panel 32 can be an RGB structure, and the pixel structure of the second display panel 34 can be an RG-BG structure.

[0113] Specifically, the first display panel 32 may include a plurality of first pixels PX1 repeatedly disposed in a first direction (horizontal direction) and a second direction (vertical direction). Each first pixel PX1 may include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B disposed sequentially along the first direction.

[0114] In the first display panel 32, subpixels of the same color can be arranged in a line along a second direction (vertical direction). For example, red subpixels R can be set in the first column, green subpixels G can be set in the second column, and blue subpixels B can be set in the third column.

[0115] The second display panel 34 may include a plurality of second pixels PX2 and a plurality of third pixels PX3 alternately arranged in a first direction (horizontal direction) and a second direction (vertical direction). The second pixels PX2 may include a red sub-pixel R and a green sub-pixel G arranged sequentially along the first direction, and the third pixels PX3 may include a blue sub-pixel B and a green sub-pixel G arranged sequentially along the first direction.

[0116] In the second display panel 34, red subpixels R and blue subpixels B can be arranged alternately in odd-numbered columns, while green subpixels G can be arranged in a line in even-numbered columns. Each of the red subpixels R and blue subpixels can have a larger area than the green subpixel G.

[0117] Reference Figure 9The pixel structure of the first display panel 32 can be an RGB structure, and the pixel structure of the second display panel 34 can be an RG-BW structure.

[0118] Due to the above reference Figure 8 The RGB structure has been described, so redundant descriptions will be omitted.

[0119] The second display panel 34 may include a plurality of fourth pixels PX4 and a plurality of fifth pixels PX5 alternately arranged along a first direction (horizontal direction) and a second direction (vertical direction). The fourth pixels PX4 may include a red sub-pixel R and a green sub-pixel G arranged sequentially along the first direction, and the fifth pixels PX5 may include a blue sub-pixel B and a white sub-pixel W arranged sequentially along the first direction.

[0120] In the second display panel 34, red subpixels R and blue subpixels B can be alternately arranged in odd-numbered columns, and green subpixels G and white subpixels W can be alternately arranged in even-numbered columns. Each of the red subpixels R and blue subpixels B can have a larger area than each of the green subpixels G and white subpixels W.

[0121] Reference Figure 10 The pixel structure of the first display panel 32 can be an RGB structure, and the pixel structure of the second display panel 34 can be an M+ structure.

[0122] Due to the above reference Figure 8 The RGB structure has been described, so redundant descriptions will be omitted.

[0123] The second display panel 34 may include a plurality of sixth pixels PX6, a plurality of seventh pixels PX7, a plurality of eighth pixels PX8, and a plurality of ninth pixels PX9.

[0124] The sixth pixel PX6 may include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B arranged sequentially along the first direction. The seventh pixel PX7 may include a white sub-pixel W, a red sub-pixel R, and a green sub-pixel G arranged sequentially along the first direction. The eighth pixel PX8 may include a blue sub-pixel B, a white sub-pixel W, and a red sub-pixel R arranged sequentially along the first direction. The ninth pixel PX9 may include a green sub-pixel G, a blue sub-pixel B, and a white sub-pixel W arranged sequentially along the first direction.

[0125] The sixth pixel PX6, the seventh pixel PX7, the eighth pixel PX8, and the ninth pixel PX9 are set sequentially along the first direction. The order of the sixth pixel PX6, the seventh pixel PX7, the eighth pixel PX8, and the ninth pixel PX9 is repeated along the first direction.

[0126] The corresponding pixels in the sixth pixel PX6, the seventh pixel PX7, the eighth pixel PX8, and the ninth pixel PX9 are alternately arranged along the second direction. The order of the corresponding pixels in the sixth pixel PX6, the seventh pixel PX7, the eighth pixel PX8, and the ninth pixel PX9 is repeated along the second direction.

[0127] Figure 11 This is a view illustrating the display panel in a personal immersive display device according to a second comparative example of the present invention.

[0128] Reference Figure 11 In the second comparative example, the first display panel 32 and the second display panel 34 have the same pixel structure. For example, the pixel structure of the first display panel 32 and the second display panel 34 can be an RGB structure.

[0129] In each display panel, when all consecutively set subpixels are not illuminated, dark lines (DA) are generated, resulting in an enhanced grid effect.

[0130] In the second comparative example, since the pixel structure of the first display panel 32 and the pixel structure of the second display panel 34 are the same, the positions of the non-light-emitting sub-pixels in the two display panels 32 and 34 can be the same when the device is driven, and the positions where dark lines DA are generated can also be the same. In this case, since the dark lines DA of the first display panel 32 and the dark lines DA of the second display panel 34 overlap with each other in the user recognition image S, there is a higher probability that the user will recognize the dark lines DA, and since the dark lines DA are generated along the pixel grid, the user can have a grid perception.

[0131] Figure 12 and 13 Compared to diagrams Figure 11 A view of the display panel in a personal immersive display device according to an embodiment.

[0132] Reference Figure 12 and 13 In a personal immersive display device according to an embodiment of the present invention, the first display panel 32 and the second display panel 34 are configured with different pixel structures. For example, such as Figure 12 As shown, the pixel structure of the first display panel 32 can be an RGB structure, and the pixel structure of the second display panel 34 can be an RG-BG structure. As another example, such as... Figure 13 As shown, the pixel structure of the first display panel 32 can be an RGB structure, and the pixel structure of the second display panel 34 can be an M+ structure.

[0133] Since the pixel structure of the first display panel 32 and the pixel structure of the second display panel 34 are different from each other, the positions where dark lines DA are generated in the two display panels 32 and 34 can be different from each other.

[0134] like Figure 12 and 13 As shown, even if a dark line DA is generated due to a non-light-emitting pixel on one display panel, the sub-pixel at the position corresponding to the dark line DA can emit light on another display panel, thus preventing the dark line from being generated.

[0135] Because users perceive the dark line DA and the light emitted from the pixels of another display panel as a composite entity, the visibility of the dark line DA is reduced due to the light emitted from the pixels of the other display panel, and the grid effect brought by the dark line DA is weakened.

[0136] Figure 14 This is a block diagram illustrating the configuration of the image processing unit of a personal immersive display device according to an embodiment of the present invention.

[0137] Reference Figure 14 The image processing unit of the personal immersive display device according to an embodiment of the present invention may include: a first image processing unit 70, which generates image data for a first display panel from source image data; and a second image processing unit 80, which generates image data for a second display panel from source image data.

[0138] The first image processing unit 70 may include a first downsampling unit 71. The first downsampling unit 71 can generate image data for the first display panel 32 by downsampling the source image data. For example, a first mask can be used to convert source image data (input image) with a first resolution into image data with a second resolution lower than the first resolution.

[0139] The first image processing unit 70 may include a first distortion unit 72. The first distortion unit 72 can generate image data for the first display panel 32 by distorting source image data, for example by performing geometric processing on the image by shifting pixel positions using a first mask.

[0140] The first image processing unit 70 may include a first rendering unit 73. The first rendering unit 73 may render image data downsampled and / or distorted via the first downsampling unit 71 and / or the first distortion unit 72 to suit the pixel structure of the first display panel 32.

[0141] The second image processing unit 80 may include a second downsampling unit 81. The second downsampling unit 81 can generate image data for the second display panel 34 by downsampling the source image data, for example, by using a second mask to convert a source image (input image) with a first resolution into an image with a third resolution lower than the first resolution.

[0142] The second image processing unit 80 may include a second distortion unit 82. The second distortion unit 82 can generate image data for the second display panel 34 by distorting the source image data, for example by performing geometric processing on the image by shifting the pixel positions using a second mask.

[0143] In order to provide images without distortion using the first display panel 32 and the second display panel 34 that are offset from each other, when distorting and / or downsampling is performed using the second mask, the position where the second mask is used for distortion and / or downsampling may be offset relative to the position where the first mask is used for distortion and / or downsampling. For this purpose, the second image processing unit 80 may further include an offset application unit 83.

[0144] The offset application unit 83 can calculate the positional difference, such as offset, between source image data distorted and / or downsampled by a first mask and source image data distorted and / or downsampled by a second mask.

[0145] The offset application unit 83 can calculate the offset value by converting the offset between the first display panel 32 and the second display panel 34 into a first resolution.

[0146] The second downsampling unit 81 and the second twisting unit 82 can change the mask application method based on the offset set by the offset application unit 83. For example, when the offset is 1 pixel, the second downsampling unit 81 and the second twisting unit 82 can sample source image data at a position that differs from the position sampled by the first downsampling unit 71 and the first twisting unit 72 by 1 pixel.

[0147] The second image processing unit may include a second rendering unit 84. The second rendering unit 84 may render image data downsampled and / or distorted via the second downsampling unit 81 and / or the second distortion unit 82 to suit the pixel structure of the second display panel 34.

[0148] For example, when the source image data is RGB image data and the pixel structure of the second display panel 34 is RG-BW structure, the second rendering unit 84 can render the RGB image data into RG-BW image data to suit the RG-BW pixel structure of the second display panel 34.
