The touch sensor IC (253) may provide information regarding the detected touch input or hovering input (e.g., location, area, pressure, or time) to the processor (120). According to one embodiment, at least a part of the touch circuit (250) (e.g., touch sensor IC (253)) may be included as part of the display driver IC (230) or the display panel (210), or as part of another component (e.g., auxiliary processor (123)) placed outside the display module (160).

[0055] According to one embodiment, the display module (160) may further include at least one sensor (e.g., fingerprint sensor, iris sensor, pressure sensor, or light sensor) of the sensor module (176) or a control circuit for the same. In this case, the at least one sensor or the control circuit for the same may be embedded in a part of the display module (160) (e.g., display panel (210) or display driver IC (230)) or a part of the touch circuit (250). For example, if the sensor module (176) embedded in the display module (160) includes a biometric sensor (e.g., fingerprint sensor), the biometric sensor may obtain biometric information (e.g., fingerprint image) associated with a touch input through a part of the display panel (210). As another example, if the sensor module (176) embedded in the display module (160) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a part or the entire area of ​​the display panel (210). According to one embodiment, a touch sensor (251) or a sensor module (176) may be placed between pixels of a pixel layer of a display panel (210), or on top of or below the pixel layer.

[0056] According to one embodiment, a processor (e.g., the processor (120) of FIG. 1) may be switched to a deactivated state after transmitting various information from the processor (120) to each module. The processor (120) may be in a deactivated state in AOD (always on display) mode. The processor (120) may remain in a deactivated state in AOD mode, but when transmitting image information and / or control information to a display driver IC (230), touch sensor IC (253), pressure sensor IC (not shown), etc., it may be activated to transmit the information and then switched back to a deactivated state.

[0057] According to one embodiment, the display driver IC (230) can transmit a driving signal (e.g., driver driving signal, gate driving signal, etc.) to the display based on image information received from the processor (120). The display driver IC (230) can display various information (e.g., current time, message reception status, etc.) by the processor (120) operating on its own in sleep mode.

[0066] FIG. 3 is a drawing showing a display panel according to one embodiment of the present disclosure. FIG. 4 is a drawing showing the pixel structure of the display panel, enlarged from portion IV shown in FIG. 3. FIG. 5 is a schematic cross-sectional view of a display panel according to one embodiment of the present disclosure.

[0067] Referring to FIGS. 3 to 5, a display panel (210) according to one embodiment of the present disclosure may include a substrate (221), a main light-emitting element (300), an auxiliary light-emitting element (400), a color conversion layer (500), and a barrier (600).

[0068] In one embodiment, the substrate (221) may be divided into a plurality of pixel regions (215). A plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) may each be mounted in a plurality of pixel regions (215). The plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) may be blue micro LEDs (light-emitting diodes) that emit blue light.

[0069] In one embodiment, a plurality of main light-emitting elements (300) may include a first main light-emitting element (310), a second main light-emitting element (320), and a third main light-emitting element (330). The first to third main light-emitting elements (310, 320, 330) may each correspond to one of red, green, and blue colors, and the light emitted by each may be converted into light of the corresponding color by a color conversion layer (500).

[0070] For example, the first main light-emitting element (310) may correspond to red, and blue light emitted from the first main light-emitting element (310) may be converted into red light as it passes through the color conversion layer (500). The second main light-emitting element (320) may correspond to green, and blue light emitted from the second main light-emitting element (320) may be converted into green light as it passes through the color conversion layer (500).

[0071] In one embodiment, the color conversion layer (500) may be laminated to a plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400). The color conversion layer (500) may be formed such that light emitted from the auxiliary light-emitting element (400) passes through the color conversion layer (500) and has a first color corresponding to a defective first main light-emitting element (310) among the plurality of main light-emitting elements (300).

[0072] For example, the color of the light emitted from the auxiliary light-emitting element (400) after passing through the color conversion layer (500) may differ depending on which of the plurality of main light-emitting elements (300) is defective.

[0073] For example, if the first main light-emitting element (310) corresponds to red, the color conversion layer (500) can be formed so that light emitted from the auxiliary light-emitting element (400) passes through the color conversion layer (500) and has red.

[0074] Accordingly, even if the main light-emitting element (300) within a specific pixel area (215) is defective, the auxiliary light-emitting element (400) passes through the color conversion layer (500) and is converted into light of the corresponding color of the defective main light-emitting element (300), so that the pixel can be operated normally.

[0075] In one embodiment, even if a defective light-emitting element is found during the manufacturing process of a display panel, the corresponding pixel can be repaired normally using an already mounted auxiliary light-emitting element (400) without the need to remove the defective light-emitting element and mount a new light-emitting element on the substrate.

[0076] In one embodiment, the color conversion layer (500) may include a color conversion medium (510) and a color filter layer (520). The color conversion medium (510) may include a main color conversion medium (511) stacked on a main light-emitting element (300) and an auxiliary color conversion medium (512) stacked on an auxiliary light-emitting element (400).

[0077] In one embodiment, the main color conversion medium (511) may include a first main color conversion medium (511a) and a second main color conversion medium (511b).

[0078] The first main color conversion medium (511a) may include a red phosphor that is laminated to the first main light-emitting element (310) and is excited by light emitted from the first main light-emitting element (310) to emit light in the red wavelength band.

[0079] The second main color conversion medium (511b) may include a green phosphor that is laminated to the second main light-emitting element (320) and is excited by light emitted from the second light-emitting element (320) to emit light in a green wavelength band.

[0080] In one embodiment, the auxiliary color conversion medium (512) can convert light emitted from the auxiliary light-emitting element (400) into light of a first color corresponding to the first main light-emitting element (310) that is defective among the plurality of main light-emitting elements (300).

[0081] For example, if the first main light-emitting element (310) that is defective corresponds to red, the auxiliary color conversion medium (512) can convert the light emitted from the auxiliary light-emitting element (400) into red light.

[0082] Accordingly, even if the main light-emitting element (300) within a specific pixel area (215) is defective, the auxiliary light-emitting element (400) passes through the auxiliary color conversion medium (512) and is converted into light of the corresponding color of the defective main light-emitting element (300), so that the pixel can be operated normally.

[0083] The color filter layer (520) is positioned above a plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) and may include color filters (521, 522) of different colors and a black matrix (523). For example, the color filter layer (520) may include a main color filter (521) positioned above each of the plurality of main light-emitting elements (300), an auxiliary color filter (522) positioned above the auxiliary light-emitting element (400), and a black matrix (523) positioned to surround the plurality of color filters.

[0084] In one embodiment, the main color filter (521) may include a second main color filter (521b) and a third main color filter (521c). The second main color filter (521b) may be positioned above the second main light-emitting element (320), and the third main color filter (521c) may be positioned above the third main light-emitting element (330).

[0085] The second main color filter (521b) may be a filter comprising a color pixel that emits a second color (e.g., green). For example, the second main color filter (521b) may be a filter comprising a polarizing element that selectively passes light of a wavelength corresponding to the second color and absorbs light of other wavelengths.

[0086] Likewise, the third main color filter (521c) may be a filter comprising a color pixel that emits a third color (e.g., blue). For example, the third main color filter (521c) may be a filter comprising a polarizing element that selectively passes light of a wavelength corresponding to the third color and absorbs light of other wavelengths.

[0087] In one embodiment, the auxiliary color filter (522) is laminated onto the auxiliary color conversion medium (512) and can selectively transmit only light of a first color (e.g., red) corresponding to a defective first main light-emitting element (310) among a plurality of main light-emitting elements (300). For example, if the defective first main light-emitting element (310) corresponds to red, the auxiliary color filter (522) can selectively transmit only red light. Accordingly, the color reproduction accuracy in the subpixel corresponding to the auxiliary light-emitting element (400) can be improved.

[0088] In one embodiment, a black matrix (523) may be disposed above a defective first main light-emitting element (310) among a plurality of main light-emitting elements (300). Accordingly, even if the defective first main light-emitting element (310) emits light unintentionally, light can be absorbed by the black matrix (523).

[0089] In one embodiment, the barrier (600) is disposed on a substrate (221) and can partition a plurality of pixel regions (215) and sub-pixel regions. The barrier (600) can be formed in a grid array to form a plurality of cells and can accommodate a light-emitting element (310, 320, 330, 400) and a color-converting medium (511a, 511b, 512) inside.

[0090] The barrier (600) surrounds each of the plurality of light-emitting elements (310, 320, 330, 400) and can output light of a color corresponding to each sub-pixel area through a color-converting medium (511a, 511b, 512) contained therein, and the light output from different sub-pixel areas can be combined to form one pixel area (215).

[0091] FIGS. 6a and 6b are cross-sectional views of a display panel according to another embodiment of the present disclosure.

[0092] Referring to FIG. 6a, the auxiliary color conversion medium (512) can convert light emitted from the auxiliary light-emitting element (400) into white light, and the auxiliary color filter (522) can selectively transmit only the light of the first color corresponding to the first main light-emitting element (310) that is defective among the plurality of main light-emitting elements (300).

[0093] In one embodiment, the auxiliary color conversion medium (512) is laminated to the auxiliary light-emitting element (400) and may include a red phosphor that emits light in the red wavelength band and a green phosphor that emits light in the green wavelength band, both of which are excited by light emitted from the auxiliary light-emitting element (400). Accordingly, blue light emitted from the auxiliary light-emitting element (400) can be converted into white light as it passes through the auxiliary color conversion medium (512).

[0094] For example, before the color conversion medium (511b, 512) is laminated onto the light-emitting element (310, 320, 330, 400), it may be discovered that the first main light-emitting element (310) is defective. In this case, a black matrix (523) may be placed on the upper side of the first main light-emitting element (310) without laminating the color conversion medium. Additionally, on the upper side of the auxiliary light-emitting element (400), an auxiliary color conversion medium (512) that converts light emitted from the auxiliary light-emitting element (400) into white light may be laminated, and an auxiliary color filter (522) that selectively transmits only light of a first color corresponding to the first main light-emitting element (310) may be disposed. For example, if the defective first main light-emitting element (310) corresponds to red, the blue light emitted from the auxiliary light-emitting element (400) may be converted into white light by the auxiliary color conversion medium (512) and then converted into red light by the auxiliary color filter (522).

[0095] At this time, the main color conversion medium (511) can also convert the light emitted from the main light-emitting element (300) into white light, and the color of the white light can be converted into one of red, green, or blue by the main color filter (521).

[0096] Additionally, although FIG. 6a illustrates a structure in which a color-converting medium is not laminated on the first main light-emitting element (310), it is not limited thereto, and a color-converting medium may also be laminated on the first main light-emitting element (310) as in FIG. 5. For example, a color-converting medium (511) corresponding to each of the main light-emitting elements (310, 320, 330) is laminated, and an auxiliary color-converting medium (512) that converts light emitted from the auxiliary light-emitting element (400) into white light is laminated on the upper side of the auxiliary light-emitting element (400), after which it may be discovered that the first main light-emitting element (310) is defective. In this case, a black matrix (523) is disposed on the upper side of the first main light-emitting element (310), and an auxiliary color filter (522) that selectively transmits only light of the first color corresponding to the first main light-emitting element (310) may be disposed on the upper side of the auxiliary color conversion medium (512).

[0097] Referring to FIG. 6b, a color-converting medium (511a, 511b, 511c) that converts light emitted from each light-emitting element into white light can be stacked not only on the auxiliary light-emitting element (400) but also on the main light-emitting elements (310, 320, 330).

[0098] For example, after the same color conversion medium (e.g., color conversion medium (511a, 511b, 511c), and auxiliary color conversion medium (512)) is stacked on both the main light-emitting element (310, 320, 330) and the auxiliary light-emitting element (400), it may be discovered that the first main light-emitting element (310) is defective. In this case, a black matrix (523) may be placed on the upper side of the first main light-emitting element (310), and an auxiliary color filter (522) that selectively transmits only light of the first color corresponding to the first main light-emitting element (310) may be placed on the upper side of the auxiliary color conversion medium (512).

[0099] For example, depending on the manufacturing process of the display panel and the time of detection of defects in the light-emitting element, the structure of the color conversion medium and the color filter layer (520) can be varied.

[0100] FIGS. 7a to 7c are drawings illustrating the pixel structure of a display panel according to various embodiments of the present disclosure. Referring to FIGS. 7a to 7c, the number of auxiliary light-emitting elements (400) arranged per pixel area (215) may vary.

[0101] For example, referring to FIG. 7a, two auxiliary light-emitting elements (400) may be arranged per pixel area (215). Also, referring to FIG. 7b, three auxiliary light-emitting elements (400) may be arranged per pixel area (215). Also, referring to FIG. 7c, one auxiliary light-emitting element (400) may be arranged per two pixel areas (215).

[0102] Specifically, the auxiliary light-emitting element (400) may be arranged in a zigzag shape such that the row of the pixel area (215) changes whenever the column of the grid-type pixel area (215) changes, as in the upper structure of FIG. 7c. Alternatively, the auxiliary light-emitting element (400) may be placed only in the pixel area (215) of one of the two adjacent columns of the grid-type pixel area (215), as in the lower structure of FIG. 7c.

[0103] Additionally, some of the multiple pixel regions (215) may have the upper structure of FIG. 7c, and others may have the lower structure of FIG. 7c. However, the structure of FIG. 7c illustrates an exemplary structure in which one auxiliary light-emitting element (400) is placed for every two pixel regions (215), and the placement of the auxiliary light-emitting element (400) is not limited thereto.

[0104] FIGS. 8a to 8d are drawings illustrating a pentile matrix pixel structure of a display panel according to various embodiments of the present disclosure.

[0105] Referring to FIGS. 8a to 8d, a plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) can be arranged in a pentile matrix structure. For example, a plurality of main light-emitting elements (300) can be arranged in an RGBG pentile matrix structure within one pixel area (215), and auxiliary light-emitting elements (400) can be arranged in a pentile matrix structure within a plurality of pixel areas (215).

[0106] In one embodiment, a plurality of main light-emitting elements (300) may include a first main light-emitting element (310), a second main light-emitting element (320), a third main light-emitting element (330), and a fourth main light-emitting element (340). The first to fourth main light-emitting elements (310, 320, 330, 340) may each correspond to one of red, green, and blue colors.

[0107] For example, the first main light-emitting element (310) may correspond to red, the second and fourth main light-emitting elements (320, 340) may correspond to green, and the third main light-emitting element (330) may correspond to blue. The light emitted by each of the first to fourth main light-emitting elements (310, 320, 330, 340) may be converted into light of each corresponding color by the color conversion layer (500).

[0108] For example, referring to FIG. 8a, the auxiliary light-emitting element (400) may be arranged to be surrounded by four main light-emitting elements (300), but is not limited thereto. Additionally, the auxiliary light-emitting element (400) may be arranged in multiple numbers per pixel area (215).

[0109] For example, referring to FIG. 8b, two auxiliary light-emitting elements (400) may be arranged per pixel area (215). Also, referring to FIG. 8c, three auxiliary light-emitting elements (400) may be arranged per pixel area (215). Also, referring to FIG. 8d, four auxiliary light-emitting elements (400) may be arranged per pixel area (215).

[0110] That is, referring to the structure of FIG. 8a, one auxiliary light-emitting element (400) may be placed in one pixel area (215). Also, referring to the structure of FIG. 8b, a total of five auxiliary light-emitting elements (400) may be placed in one pixel area (215). Also, referring to the structure of FIG. 8c, a total of five auxiliary light-emitting elements (400) may be placed in one pixel area (215). Also, referring to the structure of FIG. 8d, a total of nine auxiliary light-emitting elements (400) may be placed in one pixel area (215).

[0111] FIGS. 9a to 9c are drawings illustrating a case in which a plurality of main light-emitting elements are defective in a single pixel area.

[0112] Referring to FIGS. 9a through 9c, a plurality of pixel regions (215) may include a first pixel region (215a) and a plurality of second pixel regions (215b). The first pixel region (215a) is an area where a defective main light-emitting element (300) is placed, and the plurality of second pixel regions (215b) may be areas adjacent to the first pixel region (215a). The plurality of second pixel regions (215b) may be arranged to surround the first pixel region (215a).

[0113] In one embodiment, two defective main light-emitting elements (300) may be disposed in the first pixel area (215a). That is, two of the first to fourth main light-emitting elements (310, 320, 330, 340) may be defective. FIGS. 9a and 9b illustrate the case where the third main light-emitting element (330) and the fourth main light-emitting element (340) are defective, but are not limited thereto.

[0114] In one embodiment, the color conversion layer (500) may be formed such that light emitted from an auxiliary light-emitting element (400) of a first pixel area (215a) has a first color corresponding to a defective first main light-emitting element (310) of the first pixel area (215a). Additionally, the color conversion layer (500) may be formed such that light emitted from an auxiliary light-emitting element (400) of at least one of a plurality of second pixel areas (215b) has a second color corresponding to a defective second main light-emitting element (320) of the first pixel area (215a).

[0115] Referring to FIGS. 9a and 9b, among the four main light-emitting elements (400) placed in the first pixel area (215a), the third main light-emitting element (330) and the fourth main light-emitting element (340) may be defective. For example, if the fourth main light-emitting element (340) corresponds to green, the light emitted from the auxiliary light-emitting element (400) of the first pixel area (215a) may be converted into green light by the color conversion layer (500).

[0116] Additionally, when the third main light-emitting element (330) corresponds to blue, light emitted from the auxiliary light-emitting element (400) of one of the plurality of second pixel areas (215b) can be converted into blue light by the color conversion layer (500).

[0117] Additionally, referring to FIG. 9b, when the third main light-emitting element (320) corresponds to blue, light emitted from the auxiliary light-emitting element (400) of two of the plurality of second pixel areas (215b) can be converted into blue light by the color conversion layer (500).

[0118] For example, if a plurality of main light-emitting elements (300) (e.g., third main light-emitting element (330), fourth main light-emitting element (340)) within the first pixel area (215a) are defective, the role of some of the defective main light-emitting elements (300) (e.g., third main light-emitting element (330), fourth main light-emitting element (340)) can be replaced by auxiliary light-emitting elements (400) in the surrounding pixel area (215b).

[0119] Referring to FIG. 9c, three of the four main light-emitting elements (300) placed in the first pixel area (215a) may be defective. For example, the first main light-emitting element (310), the third main light-emitting element (330), and the fourth main light-emitting element (340) may be defective, but are not limited thereto.

[0120] For example, when the first main light-emitting element (310) corresponds to red, light emitted from the auxiliary light-emitting elements (400) of two of the plurality of second pixel areas (215b) can be converted into red light by the color conversion layer (500).

[0121] Additionally, when the third main light-emitting element (330) corresponds to blue, light emitted from the auxiliary light-emitting elements (400) of two of the plurality of second pixel areas (215b) can be converted into blue light by the color conversion layer (500).

[0122] Additionally, when the fourth light-emitting element (340) corresponds to green, the light emitted from the auxiliary light-emitting element (400) of the first pixel area (215a) can be converted into green light by the color conversion layer (500).

[0123] Accordingly, even if a plurality of main light-emitting elements (300) within a single pixel area (215a) are defective, a plurality of pixel areas (215) can be operated normally with the help of a surrounding pixel area (215b).

[0124] For example, if a plurality of main light-emitting elements (300) (e.g., first main light-emitting element (310), third main light-emitting element (330), fourth main light-emitting element (340)) within a first pixel area (215a) are defective, the role of some of the defective main light-emitting elements (300) (e.g., third main light-emitting element (330), fourth main light-emitting element (340)) can be replaced by auxiliary light-emitting elements (400) in a surrounding pixel area (215b).

[0125] FIGS. 10a to 10c are diagrams illustrating how light emitted from an auxiliary light-emitting element in a normal pixel area is converted into light of a certain color.

[0126] Referring to FIGS. 10a and 10b, a plurality of pixel regions (215) may include a defective pixel region (e.g., pixel region (215a) of FIGS. 9a to 9c) in which at least one of the plurality of main light-emitting elements (300) is defective, and a normal pixel region in which all of the plurality of main light-emitting elements (300) are not defective. For example, light emitted from auxiliary light-emitting elements (400) each disposed within the plurality of normal pixel regions may pass through a color conversion layer (500) and be formed to have a color of a preset ratio.

[0127] For example, referring to FIG. 10a, a plurality of main light-emitting elements can correspond to red, green, and blue in a ratio of 1:1:1. For example, light emitted from auxiliary light-emitting elements (400) each disposed within a plurality of normal pixel areas can pass through a color conversion layer (500) and be formed to have red, green, and blue in a ratio of 1:1:1.

[0128] Additionally, referring to FIG. 10b, a plurality of main light-emitting elements can correspond to red, green, and blue in a ratio of 1:2:1. For example, light emitted from auxiliary light-emitting elements (400) each disposed within a plurality of normal pixel areas can pass through a color conversion layer (500) and be formed to have red, green, and blue in a ratio of 1:2:1.

[0129] Additionally, referring to FIG. 10c, a plurality of main light-emitting elements (300) may correspond to red, green, and blue, respectively, in a ratio of 1:2:1. For example, the first main light-emitting element (310) may correspond to red, the second and fourth main light-emitting elements (320, 340) may correspond to green, and the third main light-emitting element (330) may correspond to blue. At this time, light emitted from auxiliary light-emitting elements (400) each disposed within a plurality of normal pixel areas may pass through a color conversion layer (500) and be formed to have red, green, and blue in a ratio of 1:2:1.

[0130] For example, among a total of nine auxiliary light-emitting elements (400) each placed in nine pixel areas (215), four auxiliary light-emitting elements (400) may correspond to green, two auxiliary light-emitting elements (400) may correspond to red, and two auxiliary light-emitting elements (400) may correspond to blue. The auxiliary light-emitting element (400) placed in the central pixel area (215) may not emit light or may be obscured by the black matrix (523).

[0131] As another example, among a total of nine auxiliary light-emitting elements (400) each placed in nine pixel areas (215), four auxiliary light-emitting elements (400) may correspond to green, three auxiliary light-emitting elements (400) may correspond to red, and two auxiliary light-emitting elements (400) may correspond to blue. For example, compared to a structure of red, green, and blue in a ratio of 1:2:1, the auxiliary light-emitting element (400) placed in the central pixel area (215) may correspond to red.

[0132] Accordingly, even if the main light-emitting element (300) within the pixel area (215) is not defective, the auxiliary light-emitting elements (400) can form an additional pixel structure.

[0133] Additionally, the color conversion layer (500) can be formed so that light emitted from the auxiliary light-emitting element (400) of the normal pixel area passes through the color conversion layer (500) and has one of red, green, or blue colors.

[0134] For example, the color conversion layer (500) can be formed so that light emitted from the auxiliary light-emitting element (400) in the normal pixel area passes through the color conversion layer (500) and becomes green. Accordingly, since the light emitted from the auxiliary light-emitting element (400) is converted into green light sensitive to human vision, the auxiliary light-emitting element (400) can be driven when necessary to control the emission of green light.

[0135] For example, the color conversion layer (500) can be formed so that light emitted from the auxiliary light-emitting element (400) in the normal pixel area passes through the color conversion layer (500) and has a red color, which is the luminance limit color. Accordingly, the light emitted from the auxiliary light-emitting element (400) can assist the main light-emitting element (300) to increase the overall luminance.

[0136] Additionally, the color conversion layer (500) may be formed so that light emitted from the auxiliary light-emitting element (400) of the normal pixel area passes through the color conversion layer (500) and is converted into ultraviolet or infrared light. Accordingly, the auxiliary light-emitting element (400) may be used as a UV sensor or an IR sensor.

[0137] FIG. 11 is a diagram illustrating how light emitted from an auxiliary light-emitting element in each pixel area is converted into a certain color when normal pixel areas and defective pixel areas are mixed. Referring to FIG. 11, four main light-emitting elements (300) and one auxiliary light-emitting element (400) may be arranged per pixel area (215).

[0138] In one embodiment, a plurality of main light-emitting elements (300) may include a first main light-emitting element (310), a second main light-emitting element (320), a third main light-emitting element (330), and a fourth main light-emitting element (340). The first to fourth main light-emitting elements (310, 320, 330, 340) may each correspond to one of red, green, and blue colors.

[0139] For example, the first main light-emitting element (310) may correspond to red, the second and fourth main light-emitting elements (320, 340) may correspond to green, and the third main light-emitting element (330) may correspond to blue. The light emitted by each of the first to fourth main light-emitting elements (310, 320, 330, 340) may be converted into light of each corresponding color by the color conversion layer (500). That is, the light emitted from one pixel area (215) may pass through the color conversion layer (500) and have red, green, and blue in a ratio of 1:2:1.

[0140] For example, among the nine pixel areas (215), the first pixel area (215-1) and the second pixel area (215-2) are defective pixel areas where a defective main light-emitting element (300) is placed, and the remaining seven pixel areas (215) are all normal pixel areas where a normal main light-emitting element (300) is placed.

[0141] For example, the fourth main light-emitting element (340) corresponding to the green of the first pixel area (215-1) may be defective, and the third main light-emitting element (330) corresponding to the blue of the second pixel area (215-2) may be defective. Accordingly, the auxiliary light-emitting element (400-1) of the first pixel area (215-1) may correspond to green, and the auxiliary light-emitting element (400-2) of the second pixel area (215-2) may correspond to blue.

[0142] Below, the corresponding color of the auxiliary light-emitting element (400) placed in the remaining 7 normal pixel areas is explained in detail.

[0143] In one embodiment, the normal main light-emitting elements (300) placed in the nine pixel areas (215) may be arranged such that there are 9 first main light-emitting elements (310) corresponding to red, 17 second and fourth main light-emitting elements (320, 340) corresponding to green since one of 18 is defective, and 8 third main light-emitting elements (330) corresponding to blue since one of 9 is defective.

[0144] In one embodiment, the ratio of the brightness of the main light-emitting element (300) to the brightness of the auxiliary light-emitting element (400) can be assumed to be 1:K. Among the auxiliary light-emitting elements (400) arranged in seven normal pixel areas, a corresponds to red, b corresponds to green, and c corresponds to blue.

[0145] [Mathematical Formula 1]

[0146]

[0147] Here, a may be the number of auxiliary light-emitting elements (400) corresponding to the red of the normal pixel area, b may be the number of auxiliary light-emitting elements (400) corresponding to the green of the normal pixel area, and c may be the number of auxiliary light-emitting elements (400) corresponding to the blue of the normal pixel area.

[0148] In one embodiment, the color-specific luminance ratio of all main light-emitting elements (300) and auxiliary light-emitting elements (400) placed in nine pixel areas (215) can be set to be the same as the color-specific luminance ratio of normal pixel areas (e.g., the luminance ratio of red, green, and blue is 1:2:1). This can be expressed by the following mathematical formula.

[0149] [Mathematical Formula 2]

[0150]

[0151] Here, R can be the luminance of red light, G can be the luminance of green light, and B can be the luminance of blue light.

[0152] According to the preset K value, integers a, b, and c that maximally satisfy the above-described [Equation 1] and [Equation 2] can be calculated to determine the corresponding color of the auxiliary light-emitting element (400) placed in the 7 normal pixel areas. For example, a can be determined to be 2, b to be 3, and c to be 2.

[0153] Accordingly, even if some main light-emitting elements (300) are defective, they can be corrected by auxiliary light-emitting elements (400) to maintain the target brightness ratio while simultaneously increasing the brightness overall.

[0154] FIGS. 12 and FIGS. 13 are drawings illustrating a method for manufacturing a display panel according to one embodiment of the present disclosure.

[0155] Referring to FIG. 12 and FIG. 13, a method for manufacturing a display panel according to one embodiment of the present disclosure may include: a step (10) of placing a substrate (221) divided into a plurality of pixel regions; a step (20) of placing a plurality of main light-emitting elements (310, 320, 330) and an auxiliary light-emitting element (400) in each of the plurality of pixel regions; a step (30) of checking whether the plurality of main light-emitting elements (310, 320, 330) are defective; and a step (40) of stacking a color conversion layer (500) formed such that when the first main light-emitting element (310) among the plurality of main light-emitting elements (310, 320, 330) is defective, the light emitted from the auxiliary light-emitting element (400) has a first color corresponding to the first main light-emitting element (310).

[0156] In one embodiment, a plurality of main light-emitting elements (310, 320, 330) and auxiliary light-emitting elements (400) may be arranged on a substrate (221) provided with a barrier (600) that partitions a sub-pixel area. The plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) may be blue micro LEDs (light-emitting diodes) that emit blue light.

[0157] In one embodiment, a plurality of main light-emitting elements (300) may include a first main light-emitting element (310), a second main light-emitting element (320), and a third main light-emitting element (330). The first to third main light-emitting elements (310, 320, 330) may each correspond to one of red, green, and blue, and the light emitted by each may be converted into light of the corresponding color by a color conversion layer (500). The plurality of main light-emitting elements (310, 320, 330) may each correspond to red, green, and blue.

[0158] Afterward, a plurality of main light-emitting elements (310, 320, 330) can be driven to check whether the light-emitting elements are defective. If the first main light-emitting element (310) is defective, a color conversion layer (500) can be laminated so that the light emitted from the auxiliary light-emitting element (400) has a red color corresponding to the first main light-emitting element (310).

[0159] In one embodiment, the color conversion layer (500) may include a color conversion medium (510) and a color filter layer (520). The color conversion medium (510) may include a main color conversion medium (511) stacked on a main light-emitting element (300) and an auxiliary color conversion medium (512) stacked on an auxiliary light-emitting element (400).

[0160] In one embodiment, the main color conversion medium (511) may include a second main color conversion medium (511b) that is laminated to the second main light-emitting element (320). The second main color conversion medium (511b) may include a green phosphor that is excited by light emitted from the second main light-emitting element (320) and emits light in a green wavelength band.

[0161] In one embodiment, the auxiliary color conversion medium (512) can convert light emitted from the auxiliary light-emitting element (400) into light of a first color (e.g., red) corresponding to the first main light-emitting element (310) that is defective among the plurality of main light-emitting elements (300).

[0162] Accordingly, even if the main light-emitting element (300) within a specific pixel area is defective, the auxiliary light-emitting element (400) passes through the auxiliary color conversion medium (512) and is converted into light of the corresponding color of the defective main light-emitting element (300), so the pixel can be operated normally.

[0163] In one embodiment, the color filter layer (520) may be disposed above a plurality of main light-emitting elements (300) and auxiliary light-emitting elements (400) and may include color filters (521, 522) of different colors and a black matrix (523). For example, the color filter layer (520) may include a main color filter (521) disposed above each of a plurality of main light-emitting elements (300), an auxiliary color filter (522) disposed above an auxiliary light-emitting element (400), and a black matrix (523) disposed to surround the plurality of color filters.

[0164] In one embodiment, the main color filter (521) may include a second main color filter (521b) and a third main color filter (521c). The second main color filter (521b) may be positioned above the second main light-emitting element (320), and the third main color filter (521c) may be positioned above the third main light-emitting element (330).

[0165] In one embodiment, the second main color filter (521b) may be a filter comprising a color pixel that emits a second color (e.g., green). For example, the second main color filter (521b) may be a filter comprising a polarizing element that selectively passes light of a wavelength corresponding to the second color and absorbs light of other wavelengths.

[0166] Likewise, the third main color filter (521c) may be a filter comprising a color pixel that emits a third color (e.g., blue). For example, the third main color filter (521c) may be a filter comprising a polarizing element that selectively passes light of a wavelength corresponding to the third color and absorbs light of other wavelengths.

[0167] In one embodiment, the auxiliary color filter (522) is laminated onto the auxiliary color conversion medium (512) and can selectively transmit only light of a first color (e.g., red) corresponding to a defective first main light-emitting element (310) among a plurality of main light-emitting elements (300). Accordingly, the color reproduction accuracy in the subpixel corresponding to the auxiliary light-emitting element (400) can be improved.

[0168] In one embodiment, the black matrix (523) may be placed above the defective first main light-emitting element (310). That is, the black matrix (523) may be placed above the defective first main light-emitting element (310) without stacking a color-changing medium. Accordingly, even if the defective first main light-emitting element (310) emits light unintentionally, light can be absorbed by the black matrix (523).

[0169] FIGS. 14 to 16 are drawings illustrating a method for manufacturing a display panel according to another embodiment of the present disclosure.

[0170] Referring to FIGS. 143 to 16, a method for manufacturing a display module according to another embodiment of the present disclosure may further include, after the operation (20) of arranging the light-emitting element of FIG. 12, the operation (25) of stacking an auxiliary color-converting medium (512) that converts light emitted from the auxiliary light-emitting element (400) into white light on the auxiliary light-emitting element (400).

[0171] That is, according to the flowchart illustrated in FIG. 14, unlike FIG. 12, after a color-changing medium is laminated onto the main light-emitting elements (310, 320, 330) and the auxiliary light-emitting elements (400), the defect status of the main light-emitting elements (310, 320, 330) can be checked.

[0172] As illustrated in FIG. 15, the main color-changing medium (511) stacked on the main light-emitting element (300) may include a first main color-changing medium (511a) and a second color-changing medium (511b). The first main color-changing medium (511a) may include a red phosphor, and the second main color-changing medium (511b) may include a green phosphor.

[0173] Alternatively, as illustrated in FIG. 16, the main color conversion medium (511) may include first to third main color conversion media (511a, 511b, 511c) that are respectively stacked on first to third main light-emitting elements (310, 320, 330) and convert light emitted from the light-emitting elements into white light.

[0174] At this time, since it is before it is confirmed which of the first to third main light-emitting elements (310, 320, 330) is defective, an auxiliary color-converting medium (512) that converts the light emitted from the auxiliary light-emitting element (400) into white light may be laminated on the auxiliary light-emitting element (400).

[0175] Afterward, the type of auxiliary color filter (522) can be determined by checking whether the main light-emitting element (310, 320, 330) is defective. Specifically, if it is confirmed that the first main light-emitting element (310) is defective, the type of auxiliary color filter (522) can be determined so that the light emitted from the auxiliary light-emitting element (400) passes through the auxiliary color filter (522) and changes to the first color.

[0176] That is, the operation (40) of stacking the color conversion layer of FIG. 12 may be the operation (40-1) of stacking an auxiliary color filter (522) that selectively transmits only light of the first color (e.g., red) in FIG. 14 onto an auxiliary color conversion medium (512).

[0177] Accordingly, even if the first main light-emitting element (310) is defective, the auxiliary light-emitting element (400) passes through the auxiliary color filter (522) and is converted into light of the corresponding color of the defective first main light-emitting element (310), so the corresponding pixel can be operated normally.

[0178] A display panel (210) according to various embodiments of the present disclosure may include a substrate (221) divided into a plurality of pixel regions (215), a plurality of main light-emitting elements (300, 310, 320, 330) and auxiliary light-emitting elements (400) each mounted in a plurality of pixel regions (215), and a color conversion layer (500) stacked on the plurality of main light-emitting elements (300, 310, 320, 330) and auxiliary light-emitting elements (400).

[0179] According to various embodiments, the color conversion layer (500) may include an auxiliary color conversion medium (512) that is laminated to an auxiliary light-emitting element (400) and converts light emitted from the auxiliary light-emitting element (400) into light of a first color.

[0182] According to various embodiments, the color conversion layer (500) may include a color filter layer (520) comprising color filters (521, 522) of different colors and a black matrix (523), which is disposed above a plurality of main light-emitting elements (300, 310, 320, 330) and an auxiliary light-emitting element (400). According to various embodiments, a black matrix (523) may be disposed above the first main light-emitting element (310).

[0183] According to various embodiments, a plurality of main light-emitting elements (300, 310, 320, 330) and auxiliary light-emitting elements (400) can be arranged in a pentile matrix structure.

[0184] According to various embodiments, auxiliary light-emitting elements (400) may be arranged in multiple numbers per pixel area (215).

[0185] According to various embodiments, a plurality of pixel regions (215) may include a first pixel region (215a) and a plurality of second pixel regions (215b) adjacent to the first pixel region (215a). According to various embodiments, a color conversion layer (500) may be formed such that light emitted from an auxiliary light-emitting element (400) of the first pixel region (215a) has a first color corresponding to a defective first main light-emitting element (310) of the first pixel region (215a), and light emitted from an auxiliary light-emitting element (400) of at least one of the plurality of second pixel regions (215b) has a second color corresponding to a defective second main light-emitting element (320) of the first pixel region (215a).

[0186] According to various embodiments, a plurality of main light-emitting elements (300, 310, 320, 330) may correspond to red, green, and blue, respectively, at a preset ratio. According to various embodiments, the color conversion layer (500) may be formed so that light emitted from auxiliary light-emitting elements (400) of a plurality of pixel areas (215) passes through the color conversion layer (500) to have a color at a preset ratio.

[0187] According to various embodiments, the preset ratio may be 1:1:1 or 1:2:1.

[0188] According to various embodiments, a plurality of pixel regions (215) may include a defective pixel region in which at least one of the plurality of main light-emitting elements (300, 310, 320, 330) is defective, and a normal pixel region in which all of the plurality of main light-emitting elements (300, 310, 320, 330) are not defective. According to various embodiments, the color conversion layer (500) may be formed such that light emitted from an auxiliary light-emitting element (400) of the normal pixel region passes through the color conversion layer (500) and has one of red, green, or blue colors.

[0189] According to various embodiments, a plurality of pixel regions (215) may include a defective pixel region in which at least one of the plurality of main light-emitting elements (300, 310, 320, 330) is defective, and a normal pixel region in which all of the plurality of main light-emitting elements (300, 310, 320, 330) are not defective.
