[0043] In this specification, it will be understood that when an element (or region, layer, or portion, etc.) is referred to as being "on" another element, "connected to" or "coupled to" another element, it may be disposed directly on, directly connected to or coupled to the other element, or other elements may be disposed between the element and the other element.

[0044] The same reference numerals or symbols refer to the same elements throughout. In the drawings, the thickness, proportions, and dimensions of the elements are exaggerated for the purpose of effectively describing the technical content. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed elements.

[0045] It will be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements will not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. For example, a first element may be referred to as a second element without departing from the scope of the inventive concept. Similarly, a second element may be referred to as a first element. In this specification, unless the context clearly indicates otherwise, the singular expressions “a” and “the (described)” are intended to include the plural forms as well.

[0046] Additionally, terms such as "below," "underneath," "on the lower side," "above," "above," or "on the upper side" may be used to describe the relationships between the elements illustrated in the accompanying drawings. These terms are relative concepts and are described based on the directions indicated in the drawings.

[0047] It will be further understood that the terms “comprising,” “including,” “having,” and / or variations thereof, when used in this specification, indicate the presence of stated features, values, steps, operations, elements, components, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, values, steps, operations, elements, components, and / or combinations thereof.

[0048] When a component is described as being "connected to" or "electrically connected to" another component, the component may be directly connected to that other component, or one or more other intermediary components may be present. For example, a component described as being "connected to" another component may be "electrically connected to" that other component. Conversely, when a component is described as being "directly connected to" another component, no intermediary component is present.

[0049] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will be further understood that terms such as those defined in common dictionaries shall be interpreted as having the meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0071] The image input module 30 can process image signals and convert them into image data that can be displayed on the display device DD. The sound input module 40 can receive external sound signals via a microphone in recording mode and / or voice recognition mode, and convert the signals into electronic voice data. The sound output module 50 can convert sound data received from the wireless communication module 20 and / or sound data stored in the memory 60, and output the converted sound data to the outside.

[0072] The external interface module 70 can serve as an interface for connecting to an external charger, wired / wireless data port and / or card (e.g., memory card, SIM / UIM card) slot, etc.

[0073] A power supply module (PSM) can supply power for the overall operation of an electronic device (ED). A PSM may include a typical battery device.

[0078] refer to Figure 5 The display device DD may include a display panel DP, an input sensing unit ISP, an anti-reflective layer RPL, a window WIN, a panel protective film PPF, a first adhesive layer AL1 and / or a second adhesive layer AL2.

[0079] The display panel DP, according to some exemplary embodiments of the present invention, can be a light-emitting display panel.

[0081] The anti-reflective layer RPL can be disposed on the input sensing unit ISP. When manufacturing the display device DD, the anti-reflective layer RPL can be directly fabricated on the input sensing unit ISP. However, some exemplary embodiments of the inventive concept are not limited thereto. The anti-reflective layer RPL can be fabricated separately as a panel and then attached to the input sensing unit ISP via an adhesive layer.

[0082] An anti-reflective layer (RPL) can be defined as an external light anti-reflective film. The RPL reduces the reflectivity of external light entering the display panel (DP) from above the display device (DD). Because of the RPL, external light is not visible to the user.

[0083] When external light propagating toward the display panel DP is reflected at the display panel DP and then returned to an external user, the external light may appear to the user as if it were reflected from a mirror. To reduce or prevent this phenomenon, the anti-reflective layer RPL may include, for example, multiple color filters that display the same colors as the pixels of the display panel DP.

[0084] A color filter can filter out external light that has the same color as a pixel. In this case, the external light may be invisible to the user. However, some exemplary embodiments of the inventive concept are not limited thereto, and the anti-reflective layer RPL may include a retarder and / or a polarizer for reducing the reflectivity of external light.

[0085] The WIN window can be placed on the anti-reflective layer RPL. The WIN window can protect the display panel DP, input sensing unit ISP and / or anti-reflective layer RPL from external scratches and impacts.

[0086] A panel protective film (PPF) can be placed below the display panel (DP). The PPF protects the lower part of the display panel (DP). The PPF can comprise flexible plastic materials such as polyethylene terephthalate (PET).

[0087] The first adhesive layer AL1 can be disposed between the display panel DP and the panel protective film PPF, and the display panel DP and the panel protective film PPF can be bonded to each other through the first adhesive layer AL1. The second adhesive layer AL2 can be disposed between the window WIN and the anti-reflective layer RPL, and the window WIN and the anti-reflective layer RPL can be bonded to each other through the second adhesive layer AL2.

[0184] The color filter CF can be positioned on the display panel DP. When viewed in a flat surface, the color filter CF can overlap with the first OLED1-1, the second OLED2-1, and / or the third OLED3-1. The black matrix BM can be positioned between the color filters CF.

[0185] The apertures B_OP1, B_OP2, and / or B_OP3 can be confined within the black matrix BM. The area of ​​the apertures B_OP1, B_OP2, and / or B_OP3 can be larger than the area of ​​the pixel apertures PX_OP1, PX_OP2, and / or PX_OP3 used to set each of the first-1 light-emitting element OLED1-1, the first-2 light-emitting element OLED1-2, the second-1 light-emitting element OLED2-1, the third-1 light-emitting element OLED3-1, and the third-2 light-emitting element OLED3-2.

[0186] When viewed on a flat surface, the first light-emitting element OLED1 and the third light-emitting element OLED3 can be disposed in the non-folded portions NFA1 and NFA2. The first portion PT1 of the black matrix BM disposed between the first light-emitting element OLED1 and the third light-emitting element OLED3 can have a first width W1.

[0187] When viewed on a plane, the first-1 light-emitting element OLED1-1 and / or the third-1 light-emitting element OLED3-1 can be disposed in the folded portion FA. The black matrix BM is disposed in the second portion PT2 between the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1, and can have a second width W2.

[0188] When viewed on a plane, the first and second light-emitting elements OLED1-2 and / or the third and second light-emitting elements OLED3-2 can be disposed in the folded portion FA. The black matrix BM is disposed in the third portion PT3 between the first and second light-emitting elements OLED1-2 and the third and second light-emitting elements OLED3-2, and can have a third width W3.

[0189] The first width W1, the second width W2, and / or the third width W3 can be defined as the distance between adjacent openings in the first direction DR1. That is, the first width W1, the second width W2, and / or the third width W3 can be defined as the distance between openings B_OP1, B_OP2, and / or B_OP3 that define the first width W1, the second width W2, and / or the third width W3, respectively.

[0190] The first width W1 may be different from the second width W2. The third width W3 may be different from the first width W1 and / or the second width W2. The first width W1 may be greater than the second width W2. The third width W3 may be greater than the first width W1. The second portion PT2 with the second width W2 and the third portion PT3 with the third width W3 may be arranged alternately in the first direction DR1. In this case, the black matrix BM may have the same thickness.

[0191] Figure 13A This is an enlarged view of the folded and non-folded parts. Figure 13B This is a diagram showing the brightness of the folded and unfolded portions.

[0192] refer to Figure 9 , Figure 12 , Figure 13A and Figure 13B The fold FA may deform due to repeated folding and unfolding. The image in the deformed area may not be clearly visible, which may lead to decreased visibility. For example, the image may look like wrinkles, and / or the image may be identified separately.

[0193] For example, depending on the user's viewing angle relative to the first direction DR1, brightness may be visually perceived as uneven. This unevenness can occur when the user's eyes are fixed on something like... Figure 13A When the image is focused on a single point, the first side S1 may be visually perceived as darker, and the second side S2 may be visually perceived as brighter. In this case, the visibility of the image may be degraded.

[0194] Black Matrix BM (see Figure 12 The area of ​​the black matrix BM can affect the brightness of the OLED light-emitting element. According to some exemplary embodiments of the present invention, the width of the black matrix BM in the first direction DR1 may not be constant and can be repeatedly changed. Since the area of ​​the black matrix BM is changed, the brightness of the OLED light-emitting element can be changed in the first direction DR1.

[0195] For example, the brightness of the first-1 light-emitting element OLED1-1 arranged on the first direction DR1 can be repeatedly changed to a first brightness and a second brightness that are different from each other. Furthermore, the brightness of the third-1 light-emitting element OLED3-1 can be repeatedly changed to a third brightness and a fourth brightness that are different from each other. Therefore, the brightness of the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1 can be repeatedly changed on the first direction DR1.

[0196] When the brightness is repeatedly changed, the image can be viewed more clearly due to the jitter effect. For example, it can reduce wrinkled portions in deformed folds (FA) and / or reduce image fragmentation.

[0197] According to some exemplary embodiments of the present invention, the second width W2 and the third width W3 are described as the widths of the black matrix BM between the color filters CF1 and CF3 corresponding to the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1. However, as long as the visibility of the display panel DP due to the brightness difference at the boundary of the wrinkled portion of the folded portion FA can be improved by controlling the width of the black matrix BM, the second width W2 and / or the third width W3 can be the widths of the black matrix BM between the color filters CF corresponding to one of the first light-emitting element OLED1, the second light-emitting element OLED2, and the third light-emitting element OLED3.

[0198] Figure 14 This is an example of a cross-sectional view of some adjacent pixels in the non-folded portion and the anti-reflective layer corresponding to these pixels. Figure 15 This is an example of a cross-sectional view of some adjacent pixels in the fold and the anti-reflective layer corresponding to these pixels.

[0199] For ease of description, Figure 14 and Figure 15 In the diagram, the circuit element layer DP-CL and the thin-film encapsulation layer TFE are shown as a single layer, and the window WIN is omitted (see...). Figure 5 ). Figure 14 and Figure 15 The black matrix BM and color filters CF1, CF2 and CF3 are further highlighted in the illustration.

[0200] refer to Figure 9 , Figure 14 and Figure 15 When viewed on a plane, the first light-emitting element OLED1 and / or the third light-emitting element OLED3 can be disposed in the non-folded portions NFA1 and NFA2. The first portion PT1 of the black matrix BM disposed between the first light-emitting element OLED1 and the third light-emitting element OLED3 can have a first thickness D1.

[0201] When viewed on a plane, the first-1 light-emitting element OLED1-1 and / or the third-1 light-emitting element OLED3-1 can be disposed in the folded portion FA. The black matrix BM is disposed in the second portion PT2 between the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1, and can have a second thickness D2.

[0202] When viewed on a plane, the first and second light-emitting elements OLED1-2 and / or the third and second light-emitting elements OLED3-2 can be disposed in the folded portion FA. The black matrix BM is disposed in the third portion PT3 between the first and second light-emitting elements OLED1-2 and the third and second light-emitting elements OLED3-2, and can have a third thickness D3.

[0203] The first thickness D1, the second thickness D2, and / or the third thickness D3 can be defined as the thicknesses with respect to the third direction DR3. The first thickness D1, the second thickness D2, and the third thickness D3 can be different from each other. For example, the first thickness D1 can be greater than the second thickness D2. The third thickness D3 can be greater than the first thickness D1. In this case, the black matrix BM can have the same width in the first direction DR1.

[0204] refer to Figure 9 , Figure 13A , Figure 13B , Figure 14 and Figure 15 In some exemplary embodiments of the present invention, the thickness of the black matrix BM in the third direction DR3 may not be constant and may be repeatedly changed. Because the thickness of the black matrix BM is changed, the brightness of the light-emitting element OLED can be changed in the first direction DR1.

[0205] For example, the brightness of the first-1 light-emitting element OLED1-1 arranged on the first direction DR1 can be repeatedly changed to a first brightness and a second brightness that are different from each other. Furthermore, the brightness of the third-1 light-emitting element OLED3-1 can be repeatedly changed to a third brightness and a fourth brightness that are different from each other. Therefore, the brightness of the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1 can be repeatedly changed on the first direction DR1.

[0206] When the brightness is repeatedly changed, the image can be viewed more clearly due to the jitter effect. For example, it can reduce wrinkled portions in deformed folds (FA) and / or reduce image fragmentation.

[0207] Figure 16 This is an example of a cross-sectional view of some adjacent pixels in the fold and the anti-reflective layer corresponding to these pixels.

[0208] For ease of description, Figure 16 In the diagram, the circuit element layer DP-CL and the thin-film encapsulation layer TFE are shown as a single layer, and the window WIN is omitted (see...). Figure 5 ). Figure 16 The black matrix BM and color filters CF1, CF2 and CF3 are further highlighted in the illustration.

[0209] refer to Figure 9 and Figure 16When viewed on a plane, the first light-emitting element OLED1 and / or the third light-emitting element OLED3 can be disposed in the non-folded portions NFA1 and / or NFA2. The first portion PT1 of the black matrix BM disposed between the first light-emitting element OLED1 and the third light-emitting element OLED3 can have a first width W1 and / or a first thickness D1.

[0210] When viewed on a plane, the first-1 light-emitting element OLED1-1 and / or the third-1 light-emitting element OLED3-1 can be disposed in the folded portion FA. The black matrix BM is disposed in the second portion PT2 between the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1, and can have a second width W2 and / or a second thickness D2.

[0211] When viewed on a plane, the first and second light-emitting elements OLED1-2 and / or the third and second light-emitting elements OLED3-2 can be disposed in the folded portion FA. The black matrix BM is disposed in the third portion PT3 between the first and second light-emitting elements OLED1-2 and the third and second light-emitting elements OLED3-2, and can have a third width W3 and a third thickness D3.

[0212] The first width W1, the second width W2, and / or the third width W3 may be different from each other. Furthermore, the first thickness D1, the second thickness D2, and / or the third thickness D3 may be different from each other.

[0213] refer to Figure 9 , Figure 13A , Figure 13B and Figure 16 In some exemplary embodiments of the present invention, the width and / or thickness of the black matrix BM in the first direction DR1 and / or the third direction DR3 may not be constant and may be repeatedly changed. Because the width and / or thickness of the black matrix BM is changed, the brightness of the light-emitting element OLED can be changed in the first direction DR1.

[0214] For example, the brightness of the first-1 light-emitting element OLED1-1 arranged on the first direction DR1 can be repeatedly changed to a first brightness and a second brightness that are different from each other. Furthermore, the brightness of the third-1 light-emitting element OLED3-1 can be repeatedly changed to a third brightness and a fourth brightness that are different from each other. Therefore, the brightness of the first-1 light-emitting element OLED1-1 and the third-1 light-emitting element OLED3-1 can be repeatedly changed on the first direction DR1.

[0215] When brightness is repeatedly changed, the image can be viewed more clearly due to the jitter effect. For example, it can reduce wrinkles in deformed folds (FA) or reduce image fragmentation.

[0216] As described above, the area of ​​the black matrix can affect the brightness of the light-emitting element. According to some exemplary embodiments of the present invention, the width of the black matrix in the first direction may not be constant and can be repeatedly changed. Since the area of ​​the black matrix is ​​changed, the brightness of the light-emitting element can be changed in the first direction.

[0217] When brightness is repeatedly altered, the image can be viewed more clearly due to the jitter effect. For example, it can reduce wrinkles in deformed folds and / or reduce image fragmentation.

[0218] One or more of the elements disclosed above may include, or be implemented therein, one or more processing circuits such as hardware including logic circuits, hardware / software combinations or combinations thereof such as processors executing software. For example, more specifically, the processing circuits may include, but are not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field-programmable gate array (FPGA), a system-on-a-chip (SoC), a programmable logic unit, a microprocessor, an application-specific integrated circuit (ASIC), etc.
