Description

BACKGROUND 1. AREA

[0001] The present inventive concepts relate to display fields and multi-vision devices. 2. DESCRIPTION OF THE STATE OF THE ART

[0002] As technologies for flat-panel display devices have been developed, the range of applications for flat-panel display devices has expanded considerably. Consequently, there has recently been a demand for the production of very large displays, which incorporate very large flat-panel display devices.

[0003] In some cases, due to problems with technologies and manufacturing costs, it may be difficult to produce very large displays which have very large flat-field display devices which have a display field size (for example, the distance between opposite corners of the display field) of 100 inches or more using a single display field.

[0004] In some cases, multi-vision devices have been developed that utilize multiple display fields. Multi-vision devices are display devices that allow for the creation of very large displays, which typically feature large flat-panel displays, by arranging multiple display fields adjacent to one another. Such multi-vision devices are capable of displaying different images on individual display fields, or of displaying a single image on individual display fields in such a way that the image is divided.

[0005] In the case of such multi-vision devices, however, heterogeneity can occur at the boundaries of individual display fields because the edge areas of the respective display fields do not show images. Therefore, there is a significant difference in visual quality between multi-vision devices and a display device that uses a single display field. SUMMARY

[0006] Some exemplary embodiments of the present inventive concepts may provide a display field without an area, not configured to display an image, and a multi-vision device which has the same.

[0007] According to some exemplary embodiments of the present inventive concepts, a display field can have a first area and a second area. The first area can have a plurality of first pixels, wherein the plurality of first pixels is contained in at least one of one or more rows of pixels and one or more columns of pixels, wherein each first pixel of the plurality of first pixels has a first pixel circuit comprising at least one switching device and at least one capacitor.The second area can contain a plurality of second pixels, wherein the plurality of second pixels is contained in at least one of the one or more rows of pixels and one or more columns of pixels, wherein the second area is adjacent to the first area, wherein the second area has an area smaller than the area of ​​the first area, and wherein every second pixel of the plurality of second pixels has a second pixel circuit that has a structure different from a structure of the first pixel circuit. The first area and the second area can be configured to collectively display a single image.

[0008] According to some exemplary embodiments of the present inventive concepts, a multi-vision device can have at least one display field comprising a plurality of first areas adjacent to one another in one or more rows and in one or more columns; and a plurality of second areas between the plurality of first areas, wherein the first areas and the second areas are configured to jointly display an individual image. The at least one display field can comprise at least one second area of ​​the plurality of second areas and at least one first area of ​​the plurality of first areas.

In some exemplary embodiments, Fig. 3 an enlarged view of section A in Fig. 2 and Fig. Figure 4 is an enlarged view of section B in Fig. 3. Furthermore, the Fig. 5A and Fig. 5B Views of a first pixel circuit and a second pixel circuit, each in Fig. 4 are contained in a first pixel and a second pixel, while Fig. 6 is a side cross-sectional view, taken along a line VI-VI' of a single display field, which is in Fig. 3 is illustrated.

[0011] With reference to the Fig. 1 and Fig. 2. A multi-vision device 10, according to some exemplary embodiments, can have an arrangement of individual display fields 11-1 to 11-N. The individual display fields 11-1 to 11-N can be connected to each other via one or more connectors. N can be any positive integer value. For example, in Fig. 1 N a value of “nine”, such that the multivision device 10 has an arrangement of nine individual display fields 11-1 to 11-9. The arrangement of individual display fields 11-1 to 11-N together form a multivision display screen of the multivision device based on the common screen sections (“display screens”) of the individual display fields 11-1 to 11-N. As in Fig. As shown in Figure 1, the multivision device 10 can be configured to display an image on a multivision display screen 90, which has the common display screens of individual display fields 11-1 to 11-N. According to some exemplary embodiments, the number (“quantity”) of individual display fields 11-1 to 11-N contained in the multivision device 10 is not limited to nine individual display fields 11-1 to 11-9, as shown in at least Figure 1. Fig. Figure 1 shows that the multi-vision device 10 can display different images on each of the individual display fields 11-1 to 11-N in the arrangement. In some exemplary embodiments, two or more of the nine individual display fields 11-1 to 11-N can display a common image. As in exemplary embodiments, which at least in Fig. As illustrated in Figure 1, the multivision device 10 can display a single image on the arrangement of individual display fields 11-1 to 11-N by subdividing the image into separate sub-images, each sub-image being a separate section of the image. As shown in Figure 1, the multivision device 10 can display a single image on the arrangement of individual display fields 11-1 to 11-N by dividing the image into separate sub-images, each sub-image being a separate section of the image. Fig. As shown in Figure 1, each individual display field 11-1 to 11-N in the arrangement can display a separate sub-image of the picture, and the arrangement of individual display fields 11-1 to 11-N can display the picture together, based on each displaying a separate sub-image of the picture. Each of the individual display fields 11-1 to 11-N can be the same or substantially the same size (for example, the same within manufacturing and / or material tolerances), but according to some exemplary embodiments, they can also be different.

[0012] With reference to the Fig. 2 and Fig. 3. A single display field 11-N can have a screen section 100 and a connector 200. The single display field 11-N, which is in at least the Fig. As illustrated in 2-3, any of the individual display fields 11-1 to 11-N, which are contained in the multivision device 10 which has the individual display field 11-1, can be used.

[0013] The screen section 100 can be arranged to cover a front surface of the single display field 11-N. Accordingly, an image displayed on the screen section 100 can be shown over an entirety or substantially an entirety (for example, an entirety within manufacturing and / or material tolerances) of the front surface of the single display field 11-N. The screen section 100 can have a first area 110 and a second area 120. Each of the first area 110 and the second area 120 can display a portion of a single image, subimage, some combination thereof, or the like. For example, some exemplary embodiments shown in Fig. 2 are illustrated, the first and second areas 110 and 120 are separate sections of a single sub-image, which is a section of the image that is jointly displayed by the individual display fields 11-1 to 11-N of the multi-vision device 10.

[0014] In some exemplary embodiments, a plurality of individual display fields 11-1 to 11-N are adjacent as in Fig. Figure 1 illustrates an arrangement such that two or more individual display fields 11-1 to 11-N are in a continuous configuration (“arrangement”). When two or more individual display fields 11-1 to 11-N are in a continuous configuration, the second area 120 and one of the first areas 110, which is arranged adjacent to it, can be contained in a single, common display field. In some exemplary embodiments, including some exemplary embodiments shown in Fig. As illustrated in Figure 2, the second area 120 of a single display field 11-N can surround the first area 110 of the single display field 11-N.

[0015] As shown in some exemplary embodiments, which are in the Fig. As illustrated in Figures 2-3, the first area 110 can be arranged in a central area of ​​the single display field 11-N. The first area 110 can have a plurality of first pixels MPA. As shown in some exemplary embodiments, which are illustrated in Fig. As illustrated in 3, the majority of first pixels (MPA) can be arranged in rows and columns. For example, as shown in Fig. As shown in Figure 3, the majority of the first pixels MPA are arranged in a matrix configuration. The first area 110 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, or a laser display.

[0016] As shown in some exemplary embodiments, which in Fig. As illustrated in Figure 3, the second area 120 can be arranged to be adjacent to the first area 110. As shown in some exemplary embodiments, which are illustrated in Figure 3, the second area 120 can be arranged to be adjacent to the first area 110. Fig. As illustrated in Figure 3, the second area 120 can have a plurality of second pixel SPAs and can be arranged in a plurality of rows and in a plurality of columns. As shown in some exemplary embodiments, which are in Fig. As illustrated in Figure 3, the plurality of rows and the plurality of columns in which the plurality of second pixels SPA are arranged can extend from the plurality of rows and the plurality of columns in which the plurality of first pixels MPA are arranged, such that at least some of the first pixels MPA and second pixels SPA are placed within a common column and / or a common row of a common matrix. Thus, the first pixel MPA and the second pixel SPA can be arranged in the plurality of rows and columns, at least partially sharing a common matrix.

[0017] The second area 120 can be located in a region of a single display field 11-N that is configured not to display an image. For example, the second area 120 can be located in an aperture region of the single display field 11-N. A region of a single display field 11-N that is configured not to display an image can be located in one or more edge regions of the single display field 11-N. In some exemplary embodiments, the second area 120 can be located adjacent to the first area 110 along an edge of the screen section 100 of the single display field 11-N. In some exemplary embodiments, the second area 120 can have an area smaller than that of the first area 110 and can be located to at least partially surround the first area 110.The majority of second pixels SPA contained in the second area 120 can have a structure different from the structure of the majority of first pixels MPA contained in the first area 110. In some exemplary embodiments, the first pixel MPA and the second pixel SPA can have different structures. In other words, each of the first pixel MPA and the second pixel SPA can have displays, each with different physical circuit structures. For example, each of the first area 110 and the second area 120 can be a separate LCD, an OLED display, a laser display, and a light-emitting diode (LED) display, respectively.

[0018] In some exemplary embodiments, in a single display field 11-N, in which the first area 110 comprises the LCD, the first area 110 may have a thin-film transistor (TFT) substrate and a color filter substrate facing each other, a liquid crystal layer arranged between them, a backlight unit arranged below the TFT substrate, and the like. Accordingly, each of the plurality of first pixels MPA may have a structure comprising a pixel circuit arranged above the TFT substrate, the liquid crystal layer, and the color filter substrate arranged thereon, with the backlight unit acting as a light source within the TFT substrate, and the like.

[0019] In some exemplary embodiments, the second area 120 can be provided as a display comprising a plurality of light-emitting diodes (LEDs). In other words, each of the second pixel SPA can comprise the plurality of LEDs arranged in at least one or more rows or in at least one or more columns, a circuit to drive a single LED, and the like. Accordingly, the second pixel SPA can have a physical circuit structure different from that of the first pixel MPA, comprising the backlight unit acting as a light source, the liquid crystal layer to control the luminance emitted by the backlight unit, and the like.

[0020] With reference to the Fig. 4 and Fig. 7A each of the plurality of second pixels SPA can have at least one of the first to third LED cells CS1, CS2 and CS3, while the first to third LED cells CS1, CS2 and CS3 can each be configured to emit red light (light having a wavelength between approximately 620 nm and 740 nm), green light (light having a wavelength between approximately 495 nm and approximately 570 nm), and blue light (light having a wavelength between approximately 450 nm and approximately 495 nm).

[0021] A partition 154 can be arranged around the first to third LED cells CS1, CS2, and CS3, preventing interference between the light emitted by each LED cell CS1, CS2, and CS3. The partition 154 can comprise a light-blocking material, for example, a black matrix resin. The color of the matrix resin is not limited to black. In some exemplary embodiments, different colors of matrix resins, such as a white matrix resin, a green matrix resin, or the like, can be used depending on the application of a product or the like. In some exemplary embodiments, a matrix resin comprising a transparent resin can be used as needed. The white matrix resin can further comprise a reflective or a scattering material.The black matrix resin can consist of at least one material such as a polymer containing a resin, a ceramic, a semiconductor, or a metal.

[0022] The partition 154 can be arranged to have a uniform or substantially uniform (for example, uniform within manufacturing and / or material tolerances) thickness such that a distance d1 between the first to third LED cells CS1, CS2, and CS3 of the second pixel SPA is uniform or substantially uniform (for example, uniform within manufacturing and / or material tolerances). In some exemplary embodiments, a distance d2 and a distance d4 can be formed in a border of the second pixel SPA to have a thickness equal to approximately half the distance d1 between the first to third LED cells CS1, CS2, and CS3 in the partition 154.The spacing between the first to third LED cells CS1, CS2, and CS3, which are arranged in the majority of adjacent second pixels SPA, can be uniform or substantially uniform (for example, uniform within manufacturing and / or material tolerances). In some exemplary embodiments, the spacing between the first to third LED cells CS1, CS2, and CS3 in a second region 120 can be equal to or substantially equal to (for example, equal within manufacturing and / or material tolerances) the spacing between the first to third subpixels CM1, CM2, and CM3 of the first pixel MPA, which has a first region 110.Accordingly, the total distance between the first to third LED cells CS1, CS2 and CS3 in the second area 120 and the first to third subpixels CM1, CM2 and CM3 in the first area 110 can be uniform or substantially uniform (for example, uniform within the manufacturing and / or material tolerances).

[0023] Referring to a side cross-sectional view of the first area 110 and the second area 120, a detailed description of the first pixel MPA and the second pixel SPA will be provided. Fig. 6 is a side cross-sectional view, taken along a line VI-VI' of the single display field, which is in Fig. 3 is illustrated.

[0024] With reference to Fig. 6. In some exemplary embodiments, the first area 110 can be formed from an LCD and can comprise a TFT substrate 162, a color filter substrate 165 facing the TFT substrate 162, and a liquid crystal layer 163 arranged between the TFT substrate 162 and the color filter substrate 165. A first polarizing plate 161 can be arranged below the TFT substrate 162, and a second polarizing plate 166 can be arranged on top of the color filter substrate 165. In some exemplary embodiments, a backlight unit 150 can be arranged below the first polarizing plate 161.

[0025] In some exemplary embodiments, the liquid crystal layer 163 can display an image in such a way that a structure of transmitted light emitted by the backlighting unit 150 is modified according to an electrical excitation provided for a liquid crystal material which at least partially comprises the liquid crystal layer 163.

[0026] In some exemplary embodiments, the TFT substrate 162 can have a plurality of gate lines formed to have a matrix shape and a plurality of data lines. A pixel electrode and a TFT can be formed in any position where the plurality of gate lines intersect the plurality of data lines. A signal voltage applied through the TFT can be exerted on the liquid crystal layer 163 by a pixel electrode, while the liquid crystal layer 163 can be configured to control a light transmittance associated with the liquid crystal layer 163 based on the applied signal voltage.

[0027] Referring to Fig. 5A and Fig. 6. The TFT substrate 162 can have a plurality of first pixel circuits MPC. One or more of the first pixel circuits MPAC can be configured to operate one or more of the first pixels MPA. The number ("quantity") of first pixel circuits MPAC can be equal to the number ("quantity") of subpixels CM1, CM2, and CM3, such that the first pixel circuits MPAC are configured to separately control one of the first to third subpixels CM1, CM2, and CM3, which at least partially contain the first pixel MPA.

[0028] With reference to Fig. In 5A, the first pixel circuit MPAC can have a switching device TR1 in which a gate line GL and a data line DL of the TFT substrate 162 are each connected to a gate electrode and a source electrode, respectively. The switching device TR1 can be a transistor, while a pixel capacitor Cp (for example, a "capacitor device") can be connected to a drain electrode of the switching device TR1. The pixel capacitor Cp can be a storage capacitor. In the case of an LCD device, the pixel capacitor Cp can further comprise a liquid crystal capacitor. In some exemplary embodiments, if and when the first region 110 comprises an OLED, the pixel capacitor Cp can be used as a current source to supply a current to an organic electroluminescent device contained in each pixel.In some exemplary embodiments, the first pixel circuit MPAC can be formed to have a shape different from the shape shown in . Fig. 5A is illustrated.

[0029] In some exemplary embodiments, the color filter substrate 165 can be arranged to face the TFT substrate 162. In some exemplary embodiments, the color filter substrate 165 can have a color filter comprising red, green, and blue (RGB) pixels 165a, 165b, and 165c, respectively, configured to produce a respective color of red, green, and blue light if and / or when light passes through it, and can have a transparent common electrode comprising indium tin oxide (ITO). A partition 165d can be arranged around the RGB pixels 165a, 165b, and 165c and can comprise the black matrix resin.

[0030] The first polarizing plate 161 and the TFT substrate 162 can be extended to the second area 120.

[0031] The second region 120 is a region in which the majority of second pixels SPA are arranged. The majority of second pixels SPA can be mounted on a circuit board 170. The circuit board 170 can be arranged on a sealing section 164, which seals or substantially seals (for example, seals within manufacturing and / or material tolerances) the liquid crystal layer 163 in the first region 110.

[0032] With reference to Fig. 5B, the 170 board can have a plurality of second pixel circuits SPAC, each configured to operate one or more of the second pixel SPAs. The second pixel circuits SPAC can each be configured to operate one of the second pixel SPAs separately.

[0033] The second pixel circuit, SPAC, has a structure different from that of the first pixel circuit, MPAC. Fig. 5A. For example, the second pixel circuit SPAC may include a power supply circuit PSC configured to supply power to the first to third LED cells CS1, CS2, and CS3; a driver circuit DC configured to control the turning on and off (e.g., selective activation) of the first to third LED cells CS1, CS2, and CS3; and a switching device TR2 in which the driver circuit DC and the first to third LED cells CS1, CS2, and CS3 are each connected to a base electrode and a collector electrode, respectively. The switching device TR2 may be a transistor, while an emitter electrode of the switching device TR2 may be connected to a pixel resistor Rp. In some exemplary embodiments, the second pixel circuit SPAC may be formed to have a shape different from the shape described in Fig. 5B is illustrated.

[0034] The majority of second pixels SPA can be arranged in an area beneath LCD fields configured not to display an image (for example, configured to be prevented from displaying an image, configured to be suppressed from displaying an image, etc.). In some exemplary embodiments, the majority of second pixels SPA can be arranged on the same layer as the color filter substrate 165 in the first area 110 and can be arranged in an area from which the black matrix resin of the color filter substrate 165 is removed in the area that does not display an image.In some exemplary embodiments, the majority of second pixels SPA can be located on an upper surface of a dense section 164, and the color filter substrate 165 can be located on an upper surface of a liquid crystal layer 163, wherein the upper surfaces of the dense section 164 and the liquid crystal layer 163 are coplanar or substantially coplanar (for example, coplanar within manufacturing and / or material tolerances). The upper surfaces of the dense section 164 and the liquid crystal layer 163 can form a common continuous layer surface, and the common continuous layer surface can be a coplanar or substantially coplanar layer surface. As a result, the majority of second pixels SPA and the color filter substrate 165 can be located on a common coplanar layer surface.

[0035] In some exemplary embodiments, an upper surface of the plurality of second pixels SPA can be arranged to have the same plane S as that of the color filter substrate 165 such that the upper surfaces of the second pixels SPA and the upper surface of the color filter substrate are coplanar or substantially coplanar (for example, coplanar within manufacturing and / or material tolerances), so that each image displayed on the first pixel MPA and the second pixel SPA can form a single image without heterogeneity. Accordingly, in some exemplary embodiments, the second pixels SPA and the first pixel MPA can be configured to jointly display a continuous image over the first and second areas 110 and 120 of a single display field 11-N.

[0036] According to some exemplary embodiments, a field driver section 140, configured to control one or more of the individual display fields 11-N, can be arranged in an area where the second area 120 overlaps the backlight unit 150. In some exemplary embodiments, the field driver section 140 can be provided as a gate drive-in panel (GIP). A protective layer 180 can be formed on the first pixel MPA and the second polarizing plate 166, so that the first pixel MPA, the second pixel SPA, and the second polarizing plate 166 can be protected from external influences.

[0037] With reference to Fig. 7A According to some exemplary embodiments, the second pixel SPA can have the first to third LED cells CS1, CS2, and CS3. First to third light control sections 151, 152, and 153 can be arranged on the first to third LED cells CS1, CS2, and CS3, while the partition 154 can be arranged between the first to third light control sections 151, 152, and 153. The first to third LED cells CS1, CS2, and CS3 are contained in a single unit, so that a single pixel can have a single unit. According to some exemplary embodiments, each of the first to third LED cells CS1, CS2, and CS3 can be provided as a separate unit. In some exemplary embodiments, a case in which the first to third LED cells CS1, CS2, and CS3 are contained in a single unit is described by way of an example.

[0038] An LED 130 can have epitaxial layers comprising a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer. The epitaxial layers can be grown on a single wafer using the same process. The active layer of the LED 130 can be configured to emit the same or substantially the same (for example, the same within manufacturing and / or material tolerances) light. For example, the active layer can emit blue light (for example, light in the range of approximately 450 nm to 495 nm) and / or ultraviolet light (for example, light in the range of 10 nm to 440 nm).

[0039] With reference to the Fig. 8A and Fig. Section 8B will contain a detailed description of an LED 130 and another LED 230. Fig. 8A and Fig. Figure 8B shows cross-sectional views of a light-emitting diode (LED), which has various structures that can be used in some exemplary embodiments of the present inventive concepts.

[0040] The LED 130, which is in Fig. As illustrated in Figure 8A, it can have a translucent substrate 131 and a light-emitting structure 133 which is arranged on the translucent substrate 131.

[0041] The translucent substrate 131 can be configured as an insulating substrate incorporating a sapphire, but is not limited to this. The translucent substrate 131 can also be configured as a conductive substrate or a semiconductor substrate that guarantees light transmission, just like the insulating substrate. A surface texture D can be formed on a surface of the translucent substrate 131. The surface texture D can increase the light extraction efficiency and can improve the quality of a single crystal that is grown.

[0042] The light-emitting structure 133 can comprise a first conductive semiconductor layer 133a, an active layer 133b, and a second conductive semiconductor layer 133c, which are arranged sequentially on the transparent substrate 131. A buffer layer 132 can be arranged between the transparent substrate 131 and the first conductive semiconductor layer 133a.

[0043] The buffer layer 132 can be used as In x Al y Ga 1-x-y The buffer layer 132 can be configured as N (0≤x≤1, 0≤y≤1, 0≤x+y≤1). For example, the buffer layer 132 can be configured as gallium nitride (GaN), aluminum nitride (AlN), aluminum gallium nitride (AlGaN), and indium gallium nitride (InGaN). Depending on the requirements, the buffer layer 132 can be formed by assembling a plurality of semiconductor layers or by stepwise changing the composition of a semiconductor.

[0044] The first conductive semiconductor layer 133a can be described as an n-type nitride semiconductor, which In x Al y Ga 1-x-y N (0≤x<1, 0≤y<1, 0 <x+y<1) erfüllt, vorgesehen sein. In einigen beispielhaften Ausführungsformen kann eine n-Typ Störstelle als Silizium (Si) vorgesehen sein. Beispielsweise kann die erste leitfähige Halbleiterschicht 133a n-Typ GaN aufweisen. Die zweite leitfähige Halbleiterschicht 133c kann als eine p-Typ Nitrid-Halbleiterschicht vorgesehen sein, welche In x Al y Ga 1-x-yN (0≤x<1, 0≤y<1, 0≤x+y<1) is satisfied. In some exemplary embodiments, a p-type defect can be provided as magnesium (Mg). For example, the second conductive semiconductor layer 133c can be formed to have a single-layer structure or can have a multi-layer structure having different compositions, as in some exemplary embodiments. The active layer 133b can have a multiple quantum well (MQW) structure in which an MQW layer and a quantum barrier layer are layered alternately. For example, the MQW and the quantum barrier layer can be formed as In x Al y Ga 1-x-y N (0≤x≤1, 0≤y≤1, 0≤x+y≤1) are provided, which have different compositions. In a specific exemplary embodiment, the MQW can be used as In x Ga 1-xN (0<x≤1) vorgesehen sein, während die Quantensperrschicht als GaN oder AlGaN vorgesehen sein kann. Die aktive Schicht 133b ist nicht auf die MQW-Struktur beschränkt sondern kann eine Einzelquanten-Topfstruktur haben.

[0045] A first electrode 134 and a second electrode 135 can be arranged in a message-etched region of the first conductive semiconductor layer 133a and the second conductive semiconductor layer 133c, respectively, thus aligning them on the same surface (a first surface). For example, the first electrode 134 can comprise at least one of aluminum (Al), gold (Au), chromium (Cr), nickel (Ni), titanium (Ti), and tin (Sn). The second electrode 135 can comprise a reflective material. For example, the second electrode 135 can comprise a material such as silver (Ag), Ni, Al, Cr, rhodium (Rh), palladium (Pd), iridium (Ir), ruthenium (Ru), Mg, zinc (Zn), platinum (Pt), Au, or the like, and can have a single-layer, two-layer, or more-layer structure.

[0046] A 230 LED, which is in Fig. Figure 8B illustrates a light-emitting structure 233 arranged on the surface of a translucent substrate 231. The light-emitting structure 233 can comprise the first conductive semiconductor layer 233a, an active layer 233b, and the second conductive semiconductor layer 233c.

[0047] The LED 230 has a first electrode 237 and a second electrode 238, which are connected to the first conductive semiconductor layer 233a and the second conductive semiconductor layer 233c, respectively. The first electrode 237 can have a connecting electrode 237a, such as a conductive via, which extends through the second conductive semiconductor layer 233c and the active layer 233b to connect to the first conductive semiconductor layer 233a, and can have a first electrode contact point 237b which is connected to the connecting electrode 237a.

[0048] The connecting electrode 237a can be surrounded by an insulating section 234 to be electrically separated from the active layer 233b and the second conductive semiconductor layer 233c. The connecting electrode 237a can be arranged in a region where the light-emitting structure 233 is etched. To reduce the contact resistance of the connecting electrode 237a, its number, shape, spacing, contact area with respect to the first conductive semiconductor layer 233a, and the like, can be appropriately designed. In some exemplary embodiments, the electric current flow can be improved by arranging the connecting electrode 237a in rows and columns on the light-emitting structure 233. The second electrode 238 can have an ohmic contact layer 238a on the second conductive semiconductor layer 233c and a second electrode contact point 238b.

[0049] The connecting electrode 237 can have a single-layer or multi-layer structure, in which the first conductive semiconductor layer 233a exhibits ohmic contact properties with respect to a conductive material, while the ohmic contact layer 238a can have a single-layer or multi-layer structure, in which the second conductive semiconductor layer 233c exhibits ohmic contact properties with respect to a conductive material. For example, the connecting electrode 237a and the ohmic contact layer 238a can be formed using a process of evaporating or sputtering one or more materials under Ag, Al, Ni, Cr, a transparent conductive oxide (TCO), and the like. The first electrode contact point 237b and the second electrode contact point 238b can each be connected to the connecting electrode 237a and the ohmic contact layer 238a, respectively, to function as an external terminal of the LED 230.For example, the first electrode contact point 237b and the second electrode contact point 238b can comprise Au, Ag, Al, Ti, tungsten (W), copper (Cu), tin (Sn), Ni, platinum (Pt), Cr, NiSn, TiW, AuSn, or a eutectic metal thereof. For example, the insulating section 234 can comprise a silicon oxide and a silicon nitride such as SiO2, SiO. x N y , Si x N y or similar features. The insulating section 234 can distribute a light-reflecting filler material within a translucent material or incorporate a distributed Bragg reflector (DBR) structure to ensure a high degree of reflectivity.

[0050] With reference to Fig. 7A The second pixel SPA can have an encapsulation section 160 which encapsulates the LED 130 and allows the first electrode and the second electrode 135 to be exposed. The encapsulation section 160 can have a high modulus of elasticity to firmly support the second pixel SPA. In some exemplary embodiments, the encapsulation section 160 can be made of a material with high thermal conductivity to effectively dissipate heat generated in the LED 130. For example, the encapsulation section 160 can be an epoxy resin or a silicon resin. In some exemplary embodiments, the encapsulation section 160 can include a light-reflecting particle to reflect light. Titanium dioxide (TiO2) or aluminum oxide (Al2O3) can be used as the light-reflecting particle. However, the light-reflecting particle is not limited to these materials.

[0051] The partition 154 has first to third light-emitting windows W1, W2, and W3 positioned according to the LED 130. The first to third light-emitting windows W1, W2, and W3 can each be configured as spaces for forming the first to third light control sections 151, 152, and 153, respectively. The partition 154 can incorporate a light-blocking material to limit and / or prevent interference between light passing through the first to third light control sections 151, 152, and 153. For example, the partition 154 can incorporate the black matrix resin.

[0052] The partition 154 is arranged to surround the side surfaces of the first to third light control sections 151, 152, and 153, thus separating these sections. The partition 154 can be arranged to be connected to the encapsulation section 160. As such, the partition 154 and the encapsulation section 160 can be configured to form a structure extending from a space between the first to third light control sections 151, 152, and 153 to each space between the LEDs 130, effectively blocking light interference between the first to third LED cells CS1, CS2, and CS3 along the entire path of light.

[0053] The first to third light control sections 151, 152, and 153 can control light emitted by the LED 130 to change into light of different colors. In some exemplary embodiments, the first to third light control sections 151, 152, and 153 can each be configured to provide red light, green light, and blue light, respectively.

[0054] In some exemplary embodiments, the LED 130 is configured to emit blue light, and the first light control section 151 and the second light control section 152 can comprise a first wavelength conversion section 151a and a second wavelength conversion section 152a, each containing a red phosphor P1 and a green phosphor P2, respectively. The first wavelength conversion section 151a and the second wavelength conversion section 152a can be formed by distributing a translucent liquid resin mixed with a wavelength conversion material, such as a red phosphor P1 or a green phosphor P2, to the first light-emitting window W1 and the second light-emitting window W2. However, the first wavelength conversion section 151a and the second wavelength conversion section 152a can also be formed using various other processes.For example, the first wavelength conversion section 151a and the second wavelength conversion section 152a can be provided as a wavelength conversion film. In some exemplary embodiments, each of the phosphors P1 and P2 can comprise one or more of a red phosphor, a green phosphor, and a blue phosphor, and the LED 130 can be configured to emit light having one or more colors, including red light, green light, and blue light.

[0055] In some exemplary embodiments, the first light-control section 151 and the second light-control section 152 can be arranged on the first wavelength-conversion section 151a and the second wavelength-conversion section 152a, and can further comprise light-filter layers 151b and 152b which selectively block blue light. The first light-emitting window W1 and the second light-emitting window W2 can be configured to be restricted to emitting one of each of red, green, and blue light, according to the light-filter layers 151b and 152b.

[0056] In some exemplary embodiments, if and / or when the LED 130 emits blue light, the third light control section 153 may lack a phosphor. Accordingly, the third light control section 153 can emit blue light, the same blue light emitted by the LED 130.

[0057] The third light-control section 153 can be formed in such a way that the translucent liquid resin, which is not mixed with a phosphor, is dispersed. According to some exemplary embodiments, the third light-control section 153 can comprise a blue wavelength conversion material or a blue-green wavelength conversion material (for example, for wavelengths in the range of 480 nm to 520 nm) to control the color coordinates of blue light. Since the wavelength conversion material is adapted to control the color coordinates of blue light provided by the third light-control section 153, the wavelength conversion material can have a lower phosphor content than that of the wavelength conversion material used in other wavelength conversion sections 151a and 152a to convert to other colors.In some exemplary embodiments, the third light control section 153 may comprise one or more of a red-wavelength conversion material, a green-wavelength conversion material, a red-green-wavelength conversion material and a red-blue-wavelength conversion material.

[0058] Fig. Figure 9 is a CIE 1931 color space chromaticity diagram illustrating a wavelength conversion material which can be used in a first light control section 151 and a second light control section 152 according to some exemplary embodiments of the present inventive concepts.

[0059] Referring to the CIE 1931 color space chromaticity diagram, as it appears in Fig. As illustrated in Figure 9, white light produced by mixing yellow, green, and red phosphors with a blue-light-emitting device, or by mixing a green-light-emitting device, a red-light-emitting device, and the blue-light-emitting device, has two or more peak wavelengths and can be arranged along a line connecting xy coordinates (0.4476; 0.4074), (0.3484; 0.3516), (0.3101; 0.3162), (0.3128; 0.3292), and (0.3333; 0.3333) in the CIE 1931 color space chromaticity diagram. Alternatively, the white light can be arranged in a region enclosed by the line and a cavity radiation spectrum. The color temperature of the white light is within a range of 2,000 K to 20,000 K. Fig. 9. The white light in the vicinity of point E (0.3333; 0.3333), which is located below the cavity radiation spectrum, can be in a state where the level of yellow light is relatively low, and can be used as an illuminating light source in an area that gives a brighter or fresher impression to the naked eye. Therefore, lighting products that utilize the white light in the vicinity of point E (0.3333; 0.3333), which is located below the cavity radiation spectrum, can be significantly more effective as a lighting device for retail spaces where consumer goods are offered for sale.

[0060] Various materials such as phosphorus and / or a quantum dot (QD=Quantum Dot=Quantum dot) can be used as a material to convert the wavelength of light emitted by an LED, which is used in some exemplary embodiments.

[0061] Phosphors can have the following empirical shapes and colors.

[0062] Oxides: yellow and green Y3Al5O 12 :Ce, Tb3Al5O 12 :Ce, Lu3Al5O 12 :Ce.

[0063] Silicates: yellow and green (Ba,Sr)2SiO4:Eu, yellow and orange (Ba,Sr)3SiO5:Ce.

[0064] Nitrides: green β-SiAlON:Eu, yellow La3Si6N 11 :Ce, orange α-SiAlON:Eu, red CaAlSiN3:Eu, Sr2Si5N8:Eu, SrSiAl4N7:Eu, SrLiAl3N4:Eu, Ln 4-x (eu z M 1-z ) x Si 12-y Al y O 3+x+y N 18-x-y(0.5≤x≤3, 0 <z<0,3, 0<y≤4), (wobei Ln wenigstens ein Element ist ausgewählt aus einer Gruppe, welche aus Gruppe IIIa-Elementen und selten Erd-Elementen besteht, und M wenigstens ein Element ist, ausgewählt aus einer Gruppe, welche aus Ca, Ba, Sr und Mg besteht).

[0065] Fluoride: KSF-based red K2SiF6:Mn 4+ , K2TiF6:Mn 4+ , NaYF4:Mn 4+ , NaGdF4:Mn 4+ and K3SiF7:Mn 4+ .

[0066] Phosphorus compositions should essentially conform to stoichiometry, and individual elements can be substituted by other elements from the same groups of the periodic table. For example, strontium (Sr) can be substituted by barium (Ba), calcium (Ca), magnesium (Mg), and the like within the alkaline earth group (II), and yttrium (Y) can be substituted by lanthanum (La)-based elements such as terbium (Tb), lutetium (Lu), scandium (Sc), gadolinium (Gd), and the like. Similarly, europium (Eu), an activator, can be substituted by cerium (Ce), terbium (Tb), praseodymium (Pr), erbium (Er), ytterbium (Yb), and the like, taking into account a desired energy level. An activator can be used alone or with a co-activator to modify the characteristics of phosphorus.

[0067] In detail, to increase reliability at high temperatures and high humidity levels, a fluoride-based red phosphor can be coated with a fluoride that does not contain manganese (Mn), or it can have organic materials on its surface or on a surface of the fluoride coating that does not contain Mn. Unlike other phosphors, the fluoride-based red phosphor can implement a narrow full width at half maximum (FWHM) of 40 nm or less, making it suitable for use in high-definition televisions, such as UHD TVs.

[0068] Table 1 below represents types of phosphors in applications to be used for a blue LED (440 nm to 460 nm) or a UV LED (380 nm to 440 nm).

[0069] In some exemplary embodiments, a wavelength conversion section can utilize a wavelength conversion material in such a way that the phosphorus is substituted by the wavelength conversion materials or a QD is mixed with the phosphorus.

[0070] Fig. Figure 7B illustrates a modified partition of a second pixel SPA according to some exemplary embodiments. The second pixel SPA in Fig. 7B is different from the second pixel SPA in Fig. 7A in that a partition 154' is provided to have a thickness d6 greater than any thickness of the first to third light control sections 151, 152 and 153. Other compositions are the same as the composition which is described in Fig. 7A is illustrated.

[0071] Since the partition 154' is arranged to have a thickness greater than any thickness of the first to third light control sections 151, 152, and 153, the radiation angle of light emitted by the first to third light control sections 151, 152, and 153 may be narrower than that of some of the embodiments described above. Since a first area 110 and a second area 120 are formed using heterogeneous displays in some exemplary embodiments, the radiation angles of light emitted by a first pixel MPA and a second pixel SPA may differ.As such, if the radiation angles of light emitted by the first area 110 and the second area 120 are different, distortion can occur in which the luminance or color of an image displayed in a first and second area of ​​a display appears different from the actual image, depending on the user's position when viewing the display. In some exemplary embodiments, the thickness of the partition 154' is designed to be d6 greater than each thickness of the first to third light control sections 151, 152, and 153, thereby controlling the radiation angles of light emitted by the first and second areas to be uniform. Thus, the image can be displayed without distortion regardless of the user's position when viewing the display.

[0072] Fig. Figure 10 is a block diagram illustrating the composition of a single display field 11-N according to some exemplary embodiments. The single display field 11-N, which is in at least Fig. As illustrated in 10, any of the individual display fields 11-1 to 11-N which are contained in the multivision device 10 can be used.

[0073] A single display field 11-N comprises a screen section 100, a display controller 400, a field controller 300, and a connector 200. In some exemplary embodiments, at least the display controller 400 and the field controller 300 can be contained in a common field controller. The common field controller can be configured to implement some or all elements of the field controller 300 and the display controller 400.

[0074] At least one of the Field Controller 300 and the Display Controller 400 can be implemented using hardware components, software components, or a combination thereof. For example, the hardware components can include microcontrollers, memory modules, sensors, amplifiers, bandpass filters, analog-to-digital converters, processing devices, or the like. A processing device can be implemented using one or more hardware devices configured to execute and / or perform program code by carrying out arithmetic, logical, and / or input / output operations.The processing device(s) may include a processor, a controller and an arithmetic logic unit, a digital signal processor, a microcomputer, a field-programmable arrangement, a programmable logic unit, a microprocessor, or any other device capable of responding to and executing instructions in a defined manner. The processing device may run an operating system (OS) and one or more software applications running on the OS. The processing device may also access, store, manipulate, process, and generate data in response to the execution of the software.For the sake of simplicity, the description of a processing device is used in the singular; however, a person skilled in the art will recognize that a processing device can have multiple processing elements and multiple types of processing elements. For example, a processing device can have multiple processors or a processor and a controller. Additionally, different processing configurations are possible, such as parallel processors, multi-core processors, distributed processing, or the like.

[0075] The software may comprise a computer program, a portion of code, a command, or several combinations thereof, to independently or collectively instruct and / or configure the processing device to operate as desired, thereby transforming the processing device into a special-purpose processor. The software and data may be executed permanently or temporarily on any type of machine, component, physical or virtual equipment, and / or computer storage medium or device. The software may also be distributed across networked computer systems, thus being stored and executed in a distributed manner. The software and data may be stored on one or more computer-readable recording media.

[0076] A memory can be non-volatile memory such as flash memory, phase-change random access memory (PRAM), magnetoresistive RAM (MRAM), resistive RAM (ReRAM), or ferroelectric RAM (FRAM), or volatile memory such as static RAM (SRAM), dynamic RAM (DRAM), or synchronous DRAM (SDRAM).

[0077] A processor can be a central processing unit (CPU), a controller, or an application-specific integrated circuit (ASIC), which, when instructions stored in memory are executed, configures the processor as a special-purpose computer to perform the operations of one or more of the field controller 300 and the display controller 400.

[0078] As described above, the screen section 100, which is also referred to as a display screen 100, can have multiple areas, and the screen section 100 can be configured to display a single image in such a way that the single image is divided into separate sections, and the separate sections (sub-images) of the image are displayed by separate areas of the screen section 100. In some exemplary embodiments, the screen section areas are configured to collectively display a sub-image of a larger image, which itself can collectively be displayed by a plurality of individual display fields 11-1 to 11-N.In some exemplary embodiments, the screen section 100 may have a first area 110 and a second area 120, which are heterogeneous displays configured to display one or more images according to different operations.

[0079] The display controller 400, which may include one or more examples of circuits, may include a calibration circuit configured to control a luminance value of an image signal transmitted to the first area 110 and the second area 120, in order to limit and / or prevent a difference in the luminance of the image displayed in the first area 110 and in the second area 120 due to a difference in operations to display the image in the first area 110 and the second area 120 respectively.

[0080] The field controller 300 of the single display unit 11-N can include one or more example circuits. The field controller 300 can include a custom image processor. The image processor can be configured to extract an image signal from an input image signal (data Rx) received at the single display unit 11-N through connector 200. The custom image processor can generate an image that can be displayed on screen section 100 of the single display unit 11-N according to the extracted image signal, where the image can be a limited section of a larger image (for example, a sub-image). The custom image processor can transmit an image signal (data Tx) to a single display unit 11-1 to 11-(N-1) located adjacent to the single display unit 11-N containing the image processor, via connector 200.

[0081] The field controller 300, contained within the single display field 11-N, can generate one or more images (e.g., sub-images) that can be displayed by one or more adjacent single display fields 11-1 to 11-(N-1) in the multi-vision device 10. In this regard, the field controller 300 in the single display field 11-N can be configured to determine the configuration ("arrangement," "structure," etc.) of the arrangement of connected single display fields 11-1 to 11-N in the multi-vision device 10, such that the field controller 300 determines the relative location of each single display field 11-1 to 11-N in the arrangement. The field controller 300 can determine the configuration based on accessing a stored representation of the configuration. Such a representation can be stored locally with the single display field 11-N.The field controller 300 can determine the configuration based on communication with one or more field controllers 300, at least one or more individual display fields 11-1 to 11-(N-1) which are arranged adjacent to the individual display field 11-N in the multi-vision device 10, one or more individual display fields 11-1 to 11-(N-1) which are not adjacent to the individual display field 11-N of the multi-vision device 10, some combination thereof, or the like. In some exemplary embodiments, a field controller 300 can map a received input image signal to each individual display field 11-1 to 11-N of the arrangement thereof contained in the multi-vision device 10, wherein the input image signal contains information associated with an image to be displayed by the multi-vision device 10.

[0082] One or more of the field controllers 300 of the individual display fields 11-1 to 11-N can connect separate areas of the image (e.g., sub-images) to separate individual display fields 11-1 to 11-N in the arrangement of the multi-vision device 10. The one or more field controllers 300 can divide the image into separate sub-images, which are connected to separate individual display fields 11-1 to 11-N in the multi-vision device, based on the configuration of the individual display fields 11-1 to 11-N in the multi-vision device 10. The one or more field controllers 300 can generate image data that displays at least one sub-image of the image and an individual display field 11-1 to 11-N that is connected to each sub-image of the at least one sub-image.

[0083] The one or more field controllers 300 can distribute the image data to one or more of the individual display fields 11-1 to 11-N. The one or more field controllers can therefore cause the image data to be distributed, at least partially, to at least some of the individual display fields 11-1 to 11-N by the arrangement. For example, at least one field controller 300 of a given individual display field 11-N can transfer the image data to at least one adjacent individual display field 11-(N-1) in order to cause the at least one adjacent individual display field 11-(N-1) to distribute the image data to at least one additional individual display field 11-(N-2) in the arrangement, etc.As a result, the image data can be transmitted by the entire arrangement to each of the individual display fields 11-1 to 11-N, causing each of the individual display fields 11-1 to 11-N to display a separate sub-image associated with it, such that the individual display fields 11-1 to 11-N together display the image. In some exemplary embodiments, a separate hub, configured to distribute separate sub-images of an image displayed in the individual display fields 11-1 to 11-N of the multi-vision device 10 to the respective corresponding individual display fields 11-1 to 11-N, may be absent from the multi-vision device 10. A general multivision device 10 can process an image displayed in the single display field 11-1 to 11-N in a separate or separate control device in order to be distributed to each single display field 11-1 to 11-N via the stroke.In some exemplary embodiments, where the multivision device 10 extracts the image signal from the field controller 300 of each individual display field 11-1 to 11-N, the separate control device or hub is absent from the multivision device 10.

[0084] The connector 200 can receive and transmit image signals (data Rx and data Tx) at the given individual display field 11-N. The connector 200 can be a magnetic connector. In some exemplary embodiments, each of the plurality of individual display fields 11-1 to 11-N of the multivision device 10 can be connected by magnetic force of the magnetic connectors of adjacent individual display fields 11-1 to 11-N. With reference to the Fig. 11, Fig. 12A and Fig. Section 12B will provide a detailed description of this.

[0085] As in Fig. As illustrated in Figure 11, a single display field 11-1 can be connected to a single display field 11-N, which is arranged adjacent to it, by means of connectors 200, which are arranged on one or more of its side surfaces, such that the single display fields 11-1 and 11-N are connected. With reference to Fig. 11 and Fig. 12A A connector 200 can have one or more connectors 200-1, which has one or more female connectors 210a', and a connector 200-2, which has one or more male connectors 210b'. As in Fig. 11 and Fig. As shown in Figure 12, for example, the single display field 11-1 can have a connector 200-1 having three female connectors 210a', and a single display field 11-N can have a connector 200-2 having three male connectors 210b'. The female connector 210a' and the male connector 210b' can be formed from magnets having different polarities. In some exemplary embodiments, one of the female connector 210a' and the male connector 210b' can be provided as a magnet, while the other can be formed from a metal attached to the magnet. Thus, as shown in Fig. Figure 12A illustrates that in some exemplary embodiments, where the female connector 210a' and the male connector 210b' are arranged adjacent to each other (for example, when the connectors 200-1 and 200-2 are arranged adjacent to each other), the female connector 210a' and the male connector 210b' are attracted to each other by magnetic force in order to be connected, as shown in Fig. Figure 12B illustrates that connectors 200-1 and 200-2 are connected to each other. A connector 200 of a given single display panel 11-1 to 11-N may have a terminal configured to transmit and / or receive a video signal and may have a power supply terminal configured to supply electrical power to the given single display panel 11-1 to 11-N according to some exemplary embodiments. Accordingly, if and / or if cables 210a and 210b, configured to transmit and / or receive the video signal or power, are extended to the female connector 210a' and the male connector 210b' respectively, a video signal and / or electrical power can be transmitted and / or received between the single display panel 11-1 and the single display panel 11-N, which is connected to it by connectors 200-1 and 200-2.

[0086] Fig. Figure 13 is a view of an arrangement of second pixels SPAa and SPAb that configure second areas 120a and 120b of single display fields 11-1 and 11-N, in a case where a female connector 210a' is connected to a male connector 210b', as in Fig. Figure 12B illustrates this. A row and a column in which a second pixel SPAa of a single display field 11-1 has the same arrangement as those of a second pixel SPAb of a different single display field 11-N, which is arranged adjacent to it. The distances d7 and d8 between the first to third LED cells CS1a, CS2a and CS3a, which configure the second pixel of the single display field 11-1, and the distance d9 between the third LED cell CS3a and the first LED cell CS1b of the single display field 11-N, which is arranged adjacent to it, can be the same.Accordingly, in a case where the female connector 210a' is connected to the male connector 210b', pixels of the individual display fields 11-1 and 11-N, which are arranged adjacent to it, are arranged in the same rows and columns, so that separate adjacent sub-images of an image, which are connected at an interface between the individual display field 11-1 and the individual display field 11-N, where the separate sub-images are displayed by separate individual display fields 11-1 and 11-N, can be displayed together by the individual display fields 11-1 and 11-N without heterogeneity between the separate and adjacent sub-images.

[0087] Accordingly, the arrangement of individual display fields 11-1 to 11-N can jointly display an image on the multi-vision display screen 90, based on each individual display field 11-1 to 11-N displaying a separate sub-image of the image, such that a boundary between the separate adjacent sub-images is seamless or substantially seamless (for example, seamless within manufacturing and / or material tolerances). In other words, the arrangement of individual display fields 11-1 to 11-N can jointly display an image on the multi-vision display screen 90, based on each individual display field 11-1 to 11-N displaying a separate sub-image of the image, such that the displayed image is continuous or substantially continuous across the screen sections of the arrangement of individual display fields 11-1 to 11-N.

[0088] As a result, in some exemplary embodiments the separate individual display fields 11-1 to 11-N can jointly display an image which has an arrangement of sub-images, wherein each sub-image is displayed on a separate individual display field 11-1 to 11-N, wherein the arrangement of sub-images forms a display of the image seamlessly or substantially seamlessly.

[0089] A seamless or substantially seamless (e.g., without heterogeneity) display of an image can refer to a display of the separate sub-images of the image in separate individual display fields 11-1 to 11-N of the multi-vision device, wherein the image is continuous or substantially continuous between adjacent sub-images which are displayed on separate, adjacent individual display fields 11-1 to 11-N.

[0090] Fig. Figure 14 is a side cross-sectional view of a multi-vision device 20 according to some exemplary embodiments. In some exemplary embodiments, the multi-vision device 20 has a circuit board 170' of a single display field 21, which extends to a different display field 22. Since other compositions thereof are the same as those of a display field in Fig. In section 6, which is described above, repeated descriptions will be omitted.

[0091] The circuit board can be formed from a flexible circuit board or printed circuit board. In some exemplary embodiments, the circuit board 170' can be arranged to protrude from a side surface of individual display fields 21 and 22, thereby flexibly connecting the individual display field 21 with the adjacent individual display field 22. As a result, and as in Fig. As shown in Figure 14, the individual display fields 21 and 22 can together form a multi-vision display screen 90, which has a curved screen section 98.

[0092] In some exemplary embodiments, a protective layer 180', comprising a flexible material, can be arranged on a surface of the circuit board 170'. Thus, in a manner different from some exemplary embodiments described above, in which individual display fields are arranged adjacent to one another on the same surface, a plurality of individual display fields 21 and 22 can be arranged on different surfaces in some exemplary embodiments. For example, each of the individual display fields 21 and 22 can be arranged on each surface of a wall Wa. Therefore, since the multivision device 20 can seamlessly cover each surface of the wall Wa in some exemplary embodiments, an image displayed in one display field can be displayed seamlessly (for example, without heterogeneity) in a corner of the wall Wa.

[0093] Fig. Figure 15 is a side cross-sectional view of a single display field according to some exemplary embodiments. Compared to a display field in Fig. 6, which is described above, the single display field in some exemplary embodiments differs in that a display field configuring a first area of ​​110' is provided as an OLED display. Since other compositions thereof are the same as those of the display field in Fig. In section 6, which is described above, repeated descriptions will be omitted.

[0094] The first region 110' of some exemplary embodiments can include the OLED display and can comprise a TFT substrate 150', a color filter substrate 165' facing the TFT substrate 150', and an organic emission layer 163' arranged between the TFT substrate 150' and the color filter substrate 165'. The organic emission layer 163' can be formed such that an organic emission material is inserted between a pair of substrates, and a dense section 164' is formed in an end section of the pair of substrates. The organic emission layer 163' can extend to a second region 120'.

[0095] For example, the color filter substrate 165' (which is an example of an upper substrate in the claims) can be arranged to face the TFT substrate 150'. In some exemplary embodiments, the color filter substrate 165' can comprise a color filter having RGB pixels 165a', 165b', and 165c' that produce colors when light passes through it, and can have a transparent common electrode such as an ITO. A partition 165d' can be arranged around the RGB pixels 165a', 165b', and 165c' and can comprise a black matrix resin.

[0096] The second region 120' is designed as a region in which a plurality of second pixels, each having an LED device, are arranged and may include a circuit substrate 170' on which the plurality of second pixels are mounted. The circuit substrate 170' may be arranged on the sealing section 164', which seals the organic emission layer 163' of the first region 110'. A plurality of second pixels SPA' may be arranged in a region in which an area that does not display an image (an aperture area) is located between OLED displays. A plurality of second pixels may be arranged on the same layer as the color filter substrate 165' of the first region 110'.An upper surface of the plurality of second pixels SPA' can be arranged to be coplanar with the color filter substrate 165', so that the separate images displayed on the first pixel MPA' and the second pixel can together form a single image without heterogeneity (for example, seamlessly or substantially seamlessly forming a continuous or substantially continuous image). According to some exemplary embodiments, a field driver section 140' configured to control the single display field can be arranged in a region where the second region 120' is in contact with the TFT substrate 150'. In some exemplary embodiments, the field driver section 140' can be provided as a GIP.

[0097] The Fig. 16, Fig. 17, Fig. 18 and Fig. Figure 19 shows cross-sectional views of a process for creating a single display field in Fig. 6.

[0098] First, an LCD display panel 11a is installed as shown in Fig. 16 illustrated arrangements.

[0099] The LCD display field 11a of some exemplary embodiments can comprise a TFT substrate 162, a color filter substrate 165 facing the TFT substrate 162, and a liquid crystal layer 163 arranged between the TFT substrate 162 and the color filter substrate 165. An end section of the liquid crystal layer 163 can be sealed with a sealing section 164.

[0100] A first polarizing plate 161 can be arranged beneath the TFT substrate 162, while a second polarizing plate 166 can be arranged on the color filter substrate 165. In some exemplary embodiments, a field driver section 140 and a backlight unit 150 can be arranged beneath the first polarizing plate 161.

[0101] The following can be seen as in Fig. As illustrated in Figure 17, the sealing section 164, which is arranged under the color filter substrate 165, is exposed in such a way that an area which is arranged in a second area 120 in the middle of the color filter substrate 165 is removed.

[0102] The following will describe how in Fig. Figure 18 illustrates a circuit substrate 170 arranged on the sealing section 164, and a plurality of second pixels SPA can be mounted on the board 170, as shown in Fig. Figure 19 illustrates this. According to some exemplary embodiments, the majority of second pixels SPA can be arranged after they are mounted on the board 170.

[0103] Subsequently, a protective layer is formed to cover a plurality of first pixels SPA and the second polarizing plate 166, and a single display field 11-1 to 11-N in Fig. 6 can be produced.

[0104] Fig. 20 is an indoor smart network system which uses a display field according to some exemplary embodiments of the present inventive concepts.

[0105] A network system 1000 according to some exemplary embodiments can be provided as a complex smart network system that integrates lighting technology using a light-emitting semiconductor element such as an LED or the like, Internet of Things (IoT) technology, wireless communication technology, and the like. The network system 1000 can be implemented using various display panels, lighting devices, and wired or wireless communication devices, and can also be implemented by software for controlling, maintaining, and the like of a sensor, a controller, a communication method, and a network.

[0106] The Network System 1000 can be applied to an enclosed space, defined as a room within a building, such as a house or office, or to an open space, such as a park and a street, or similar. The Network System 1000 can be implemented within an IoT environment to collect and process various types of information and present that information to a user. In this case, an LED light 1200, which is part of the Network System 1000, can have a light source module that is integrated into Fig. Figure 1 illustrates this. The LED light 1200 can receive information about its environment from a gateway 1100 to control the illumination of the LED light 1200. In some exemplary embodiments, the LED light 1200 can play a role in confirming and controlling an operating state of other devices 1300 to 1800 included in the IoT environment, based on a function of visible light communication from the LED light 1200 or the like.

[0107] With reference to Fig. 20. The network system 1000 can include the gateway 1100 to process data transmitted and received according to different communication protocols, wherein the LED light 1200 is connected to communicate with the gateway 1100 and has an LED as a light source, and a plurality of devices 1300 to 1800 are connected to communicate with the gateway 1100 according to various wireless communication methods. To implement the network system 1000 based on the IoT environment, each of the devices 1300 to 1800, such as the LED light 1200, can have at least one communication module. In some exemplary embodiments, the LED light 1200 can be connected to communicate with the gateway 1100 via a wireless communication protocol such as Wi-Fi, ZigBee®, Li-Fi, or the like.In this respect, the LED light 1200 can at least have a communication module for a light 1210.

[0108] As described above, the Network System 1000 can be applied to an open space such as a street or park, as well as an enclosed space such as a house or office. In the case of a home application, the majority of devices 1300 to 1800 included in and connected to the Multi-Purpose System 1000 to communicate with the Gateway 1100 using IoT technology may include a household appliance 1300, a digital door lock 1400, a garage door lock 1500, a wall-mounted light switch 1600, a router 1700 for wireless communication networks, and a mobile device 1800 such as a smartphone, tablet, laptop, or similar device.

[0109] In network system 1000, the LED light 1200 can confirm the operating status of the various devices 1300 to 1800 by using a wireless communication network installed inside a house, such as ZigBee®, Wi-Fi, Li-Fi, or the like. Alternatively, the LED light 1200 can automatically adjust its brightness depending on the environment and situation. In some exemplary embodiments, the LED light 1200 can control the devices 1300 to 1800 contained in network system 100 via Li-Fi communication using visible light emitted by the LED light 1200.

[0110] The LED 1200 can automatically adjust its brightness via the communication module for a 1210 luminaire based on environmental information transmitted by the 1100 gateway or collected by a sensor mounted on the LED 1200. For example, the brightness of the LED 1200 can be automatically adjusted depending on the type of program being shown on a 1300 television, which displays the screen. Fig. 2, is transmitted, or the brightness of a TV screen. In this regard, the LED light 1200 can receive information about the operation of the television 1310 from the communication module for a light 1210, which is connected to the gateway 1100. The communication module for a light 1210 can be modularized to be integrated with a sensor and / or a controller contained in the LED light 1200.

[0111] For example, if a program broadcast on a TV is a drama, the lighting can be configured to create a comfortable atmosphere based on a desired (and / or alternatively predetermined) value by reducing the color temperature to 12,000 K or lower, specifically 6,000 K, and adjusting the color. Alternatively, if a program broadcast on a TV is a comedy, the network system can be configured to increase the color temperature to 6,000 K or higher, and the lighting can be adjusted to be a blue-based white light, depending on the desired (and / or alternatively predetermined) value.

[0112] In some exemplary embodiments, if a specific period of time elapses after the digital door lock 1400 is locked and no one is present inside a house, all of the LED lights 1200 that are switched on can be switched off, thereby limiting and / or preventing a waste of electricity. Alternatively, if a security mode is set by the mobile device 1800 or the like, when the digital door lock 1400 is locked and no one is inside a house, the LED light 1200 can also be kept switched on.

[0113] The operation of the LED 1200 light can also be controlled based on environmental information gathered by various sensors connected to the multi-purpose system 1000. For example, if the network system 1000 is implemented within a building, efficient building management or the efficient use of unused space can be achieved by combining a light, a position sensor, and a communication module. This allows for the collection of location information about people within the building, enabling the lighting to be switched on or off, or for the collected information to be displayed in real time. Generally, a lighting device such as the LED 1200 is installed in almost every room on each floor of the building.According to this, a sensor designed to be integrated with the LED light 1200 can collect various types of information within the building for use in property management to increase the utilization of unused space or the like.

[0114] Meanwhile, the LED luminaire 1200 can be combined with an image sensor, a storage device, the communication module for a luminaire 1210, and the like, to be used as a device for maintaining safety in the building or for detecting and responding to an emergency. For example, if a smoke sensor, a temperature sensor, or the like is mounted on the LED luminaire 1200, the occurrence of a fire or similar incident can be detected quickly, thereby significantly reducing damage. In some exemplary embodiments, the brightness of the lighting can be adjusted taking into account external weather conditions, the amount of natural light, and the like, thus saving energy and providing ideal lighting settings.

[0115] As explained above, according to exemplary embodiments of the present inventive concepts, a display field and a multi-vision device without heterogeneity can be provided on a boundary of a single display field in such a way that a light-emitting diode (LED) is mounted in an area of ​​the single display field which does not display an image.

[0116] While exemplary embodiments have been shown and described above, it will be obvious to those skilled in the art that modifications and variations can be made without deviating from the scope of the present inventive concepts as defined by the attached claims.
