Detailed Implementation

[0028] This disclosure can have various modifications and implementations therein, and therefore, specific implementations will be shown in the accompanying drawings and described in detail in the detailed description. References will follow later with the appendix. Figure 1 The effects and features of this disclosure, as well as the methods for implementing them, will become clear from the detailed description of the embodiments described below. However, this disclosure is not necessarily limited to the embodiments disclosed below and can be implemented in various forms.

[0029] In the following implementation, unless otherwise clearly indicated in the context, the singular form includes the plural form.

[0030] In the following implementation, the terms “comprising”, “having”, etc. are intended to refer to the features or components described herein, but do not exclude the possibility of adding one or more other features or components.

[0031] In the following embodiments, when a portion such as a membrane, region, component, etc. exists on or above another portion, this situation can include not only the case where it is directly on the other portion, but also the case where another membrane, region, component, etc. is arranged between the portion and the other portion.

[0032] In the following examples, terms such as connection or combination do not necessarily imply a direct and / or fixed connection or combination of two components unless the context clearly indicates otherwise, and do not exclude the existence of another component between the two components.

[0033] While each figure may represent one or more specific embodiments of the present disclosure and is drawn to scale so that relative lengths, thicknesses, and angles can be inferred from the figures, it is to be understood that the invention is not necessarily limited to the relative lengths, thicknesses, and angles shown. Changes to these values ​​may be made within the spirit and scope of the present disclosure, for example, to allow for manufacturing limitations.

[0034] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Where an element is not described in detail with respect to the drawings, it may be understood that the element is at least similar to a corresponding element described elsewhere in this disclosure.

[0035] Exemplary embodiments of this disclosure relate to optimizing pad layout in display devices to improve design flexibility and reduce the area required for interconnect circuitry. This innovation enables narrower bezels, lower costs, and better structural design in electronic devices such as smartphones, laptops, and televisions.

[0036] A key feature of the display device is that it has a pad area comprising multiple groups of panel pads with varying spacing and widths. The different distances (pitch) between the panel pads allow for more efficient use of space. This layout enables a reduction in the size of the connecting circuit board and optimizes non-display areas. By adjusting the pitch and width of the panel pads, the space required for the connecting circuit board can be minimized. This reduction allows for thinner and more compact displays, resulting in material cost savings.

[0037] Different groups of panel pads can be assigned based on function, such as power lines that require lower resistance and therefore wider pads, and touch sensor lines that can allow higher resistance and therefore use smaller, more compact pads. This selective approach can enhance efficiency without compromising performance.

[0038] Some panel pads can be set at an angle, rather than being perfectly parallel. This improves electrical connections and manufacturing tolerances, ensuring better alignment with the connecting circuit board.

[0039] The connection circuit board can include corresponding connection pads with spacing and width that match the panel pads. This connection method ensures optimal signal transmission and mechanical stability.

[0040] This arrangement offers several practical advantages. For example, narrower bezels can be achieved by reducing the non-display area. Cost savings are possible by requiring smaller interconnect circuit boards. Better integration of touch sensors and display drivers in high-resolution displays is also possible.

[0041] In addition, these structural improvements can enhance durability and manufacturing efficiency.

[0042] Figure 1 This is a schematic plan view of a display device according to an embodiment of the present disclosure. Figure 2 It is an illustrative representation of along Figure 1 A cross-sectional view of an example section taken by line I-I', and Figure 3 It is an illustrative representation of along Figure 1Another example of a cross-sectional view of the section cut by line I-I'.

[0043] refer to Figure 1 The display device 1 may include a display panel DP. In an alternative embodiment, the display device 1 may also include a connection circuit board FB or a main circuit board MB. The display panel DP, the connection circuit board FB, and the main circuit board MB may be electrically connected to each other.

[0044] The display panel DP may include a display area DA and a non-display area NDA. In some embodiments, the substrate BSL of the display panel DP may include the display area DA and a non-display area NDA adjacent to the display area DA. The display area DA is the portion where the image is displayed, and the non-display area NDA surrounding the display area DA may be a portion provided with circuitry and / or signal lines for generating and / or transmitting various signals to be applied to the display area DA. No image is displayed within the non-display area NDA.

[0045] The non-display area NDA may include multiple panel pads PP (see...) Figure 4 The pad area PA is set on the first direction DR1. The panel pad group set on the first direction DR1 can be set in the pad area PA. The display panel DP can be connected to the connection board FB in the pad area PA.

[0046] Multiple pixels PX that receive signals from signal lines can be disposed in the display area DA of the display panel DP. In an embodiment, each of the pixels PX can receive an electrical signal and display the light constituting an image. The pixels PX can be arranged in a matrix shape, spaced apart from each other in a first direction DR1 and a second direction DR2. The display panel DP can display various images by controlling the pixels PX. However, Figure 1 This is an example, and some components of pixel PX can overlap each other on a plane, and are not necessarily limited to any one implementation.

[0047] Each pixel PX may include a display element and a driving element. The display element may include various embodiments. For example, the display element may be at least one of a liquid crystal capacitor, a light-emitting element, an electrophoretic element, and an electrowetting element. However, this is described by way of example, and the display element may include various embodiments as long as it can realize an image according to electrical signals, and the display element is not necessarily limited to any one embodiment.

[0048] The driving element can control the driving of each display element of each pixel PX. The driving element may include a thin-film transistor. The display panel DP according to embodiments of this disclosure can be driven by an active method that can independently control each pixel PX.

[0049] Signal lines, such as scan lines, data lines, drive voltage lines, common voltage lines, and / or initialization voltage lines, can be disposed in the display area DA. Each pixel PX can be connected to the scan lines, data lines, drive voltage lines, common voltage lines, and / or initialization voltage lines, and can receive scan signals, data voltages, drive voltages, common voltages, and / or initialization voltages from the signal lines. Pixel PX may include light-emitting elements such as light-emitting diodes. Touch electrodes can be disposed in the display area DA of the display panel DP to detect touches from the user's fingers, etc.

[0050] The reference schematic shows a cross-section of a portion of the display area DA of the display panel DP. Figure 2 The display panel DP may have a pixel layer PXL, which is capable of generating visible light to provide visible light to the user. The type of pixels PX included in the pixel layer PXL can vary, and the current embodiment describes the case where the pixels PX are organic light-emitting diode (OLED) elements.

[0051] The display panel DP will be described in detail. The display panel DP may include a pixel layer PXL on a substrate BSL. As an alternative implementation, the display panel DP may also include an encapsulation layer TFE and an optical functional layer 110.

[0052] The substrate BSL can be formed using a variety of materials. As specific examples, the substrate BSL may include glass, metal, or other organic materials.

[0053] As an alternative implementation, the substrate BSL may include a flexible material. For example, the substrate BSL may be flexible, bendable, foldable, or rollable.

[0054] For example, the substrate BSL may comprise ultrathin glass, metal, or plastic-based materials, such as polyimide (PI) when plastic is used, and as another specific example, the substrate BSL may comprise at least one of polystyrene, polyvinyl alcohol, polymethyl methacrylate, polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polycarbonate, cellulose triacetate, and cellulose acetate propionate.

[0055] The pixel layer PXL can be formed on the substrate BSL and can include a first electrode 151, a second electrode 152, and an intermediate layer 153. In some embodiments, the first electrode 151 can be formed on the substrate BSL, the second electrode 152 can be formed on the first electrode 151, and the intermediate layer 153 can be formed between the first electrode 151 and the second electrode 152.

[0056] A buffer layer may also be formed on the first electrode 151 and the substrate BSL. The buffer layer can provide a flat surface on the substrate BSL and can block moisture or gas from permeating through the substrate BSL.

[0057] The first electrode 151 can be used as the anode, and the second electrode 152 can be used as the cathode, but this polarity order can be reversed. When the first electrode 151 is used as the anode, it can include materials with high work functions such as ITO, IZO, ZnO, and In2O3. Depending on the purpose and design conditions, the first electrode 151 can also include a reflective film, which can include materials such as Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Yb, and Ca.

[0058] When the second electrode 152 is used as a cathode, the second electrode 152 may include metals such as Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, etc. The second electrode 152 may include ITO, IZO, ZnO, In2O3, etc., to enable light transmission.

[0059] The intermediate layer 153 may include at least an organic light-emitting layer. In addition to the organic light-emitting layer, the intermediate layer 153 may optionally include at least one of a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer. When a voltage is applied to the first electrode 151 and the second electrode 152, visible light can be generated from the intermediate layer 153 (specifically, from the organic light-emitting layer of the intermediate layer 153).

[0060] A TFE encapsulation layer can be applied to the pixel layer PXL to protect the pixel PX. The TFE encapsulation layer protects the pixel layer PXL from external impacts and reduces or prevents the penetration of external foreign objects or moisture.

[0061] The encapsulation layer TFE can be formed in various types. In an optional embodiment, the encapsulation layer TFE can be formed from a transparent glass material with SiO2 as the main component. In another optional embodiment, the encapsulation layer TFE can be formed from a light-transmitting plastic material. In yet another optional embodiment, the encapsulation layer TFE can be formed using organic or inorganic films. In yet another optional embodiment, the encapsulation layer TFE can be formed by laminating one or more organic films and one or more inorganic films, and in this case, it can be formed by alternately laminating organic and inorganic films.

[0062] The display panel DP can provide an image in an upward direction (e.g., in an upward direction relative to a third direction, such as towards the light functional layer 110). The light functional layer 110 may include a base material and light functional particles.

[0063] The display panel (DP) may include thin-film transistors that transmit the signals required to drive the pixels (PX) to the pixels (PX). (Refer to...) Figure 3 Provide a detailed description.

[0064] Figure 3 It shows Figure 2 Example of modification. See reference. Figure 3 The display panel DP may include a substrate BSL', a pixel layer PXL', thin film transistors, and a packaging layer TFE'.

[0065] The thin-film transistor may include an active layer 133', a gate electrode 135', a source electrode 137', and a drain electrode 138'. These will be described in detail. A buffer layer 120' may be formed on the substrate BSL'. The buffer layer 120' can provide a flat surface on the substrate BSL' while preventing impurity elements from penetrating the substrate BSL', and can be formed from various materials capable of performing this function. The buffer layer 120' is an optional component and may be omitted.

[0066] The active layer 133' may be disposed on the buffer layer 120' in a selected pattern. The active layer 133' may include an inorganic semiconductor material such as silicon, and as an alternative embodiment may include an organic semiconductor material, and as another alternative embodiment may include an oxide semiconductor material.

[0067] A gate insulating film 136' may be formed on the active layer 133'. The gate insulating film 136' may include various insulating materials and may be formed using, for example, oxides or nitrides.

[0068] The gate electrode 135' may be formed on top of the gate insulating film 136' to correspond to a predetermined region of the active layer 133'. The gate electrode 135' may include a material with good conductivity. For example, the gate electrode 135' may contain at least one of Au, Ag, Cu, Ni, Pt, Pd, Al, and Mo, and may include alloys such as Al:Nd, Mo:W alloys, etc. However, this is only an example, and the present embodiment is not necessarily limited thereto and may include various materials.

[0069] Interlayer insulating film 139' may cover gate electrode 135'. Source electrode 137' and drain electrode 138' may be formed on interlayer insulating film 139'. Source electrode 137' and drain electrode 138' may contact selected regions of active layer 133'.

[0070] The passivation layer 140' can cover the source electrode 137' and the drain electrode 138'. A separate insulating film can be formed on the passivation layer 140' to planarize the thin-film transistor.

[0071] For example, display device 1 may include a thin-film transistor positioned on substrate BSL' and a light-emitting element positioned in display area DA on substrate BSL' and electrically connected to the thin-film transistor.

[0072] The display device 1 may also include one or more thin-film transistors electrically connected to the pixel layer PXL', and may also include one or more capacitors electrically connected to the pixel layer PXL' or the thin-film transistors.

[0073] The first electrode 151' may be formed on the passivation layer 140'. The first electrode 151' may be electrically connected to one of the source electrode 137' and the drain electrode 138'. For example, the first electrode 151' may be connected to the drain electrode 138'.

[0074] A pixel defining film 160' can be formed on the first electrode 151', and the pixel defining film 160' can expose a selected area of ​​the first electrode 151'.

[0075] An intermediate layer 153' may be formed on the first electrode 151'. The intermediate layer 153' may have an organic light-emitting layer. As an alternative embodiment, in addition to the organic light-emitting layer, the intermediate layer 153' may also include at least one of a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer.

[0076] The second electrode 152' can be formed on the intermediate layer 153'.

[0077] The encapsulation layer TFE' can be placed on the pixel layer PXL' to protect the pixel PX.

[0078] As an optional implementation, the display panel DP may also include a light functional layer 110'. The light functional layer 110' may include layers for improving, modifying, and differently controlling the characteristics of light implemented in the pixel layer PXL'.

[0079] The non-display area NDA can be adjacent to the display area DA. The non-display area NDA can be positioned on at least one side of the display area DA on the display panel DP. For example, the non-display area NDA can surround the display area DA. Figure 1 In the diagram, the boundary between the display area DA and the non-display area NDA is indicated by a dashed line. However, this is merely an example, and the non-display area NDA can have various shapes as long as it is adjacent to the display area DA, and is not necessarily limited to any one implementation.

[0080] The non-display area NDA (specifically, the pad area PA within the non-display area NDA) can be the area to which the end of the connecting circuit board FB is connected. For electrical connection to the connecting circuit board FB, multiple panel pads PP can be provided in the pad area PA. The display panel DP can be electrically connected to external components such as the connecting circuit board FB and the main circuit board MB via the pad area PA.

[0081] A driving unit that generates and / or processes various signals used to drive the display panel DP can be located in the non-display area NDA. The driving unit may include a data driving unit that applies data signals to data lines, a gate driving unit that applies gate signals to scan lines, and a signal control unit that controls the data driving unit and the gate driving unit. Based on the scan signal generated from the gate driving unit, data signals, etc., can be applied to pixels PX at a selected timing.

[0082] The connection circuit board FB can be placed in the pad area PA of the display panel DP to connect the main circuit board MB to the display panel DP. The connection circuit board FB can be located on one side of the display panel DP extending in the second direction DR2.

[0083] The connection board FB can be configured as a single component and is not necessarily limited to any one implementation. As another example, multiple connection boards FB can be provided and can be spaced apart from each other in the pad area PA in the first direction DR1.

[0084] When multiple connecting circuit boards (FB) exist, the panel pads (PP) can be set in the pad area (PA) to correspond to the connecting pads (FP) of the connecting circuit boards (FB) (see [reference]). Figure 6 ).

[0085] The connecting circuit board FB can be flexible. Therefore, the connecting circuit board FB connected to the display panel DP can be bent, causing other components connected to the connecting circuit board FB (such as the main circuit board MB) to be positioned on the rear surface of the display panel DP.

[0086] For electrical connection to the display panel DP, multiple connection pads FP can be disposed on the connection circuit board FB. The connection circuit board FB can be electrically connected to the display panel DP by overlapping the connection pads FP with the panel pads PP located in the pad area PA of the display panel DP. The connection circuit board FB can correspond to the pad area PA to transmit various electrical signals to the display area DA via the panel pads PP.

[0087] The main circuit board MB can be connected to the connecting circuit board FB, and can be connected to one end of the connecting circuit board FB, which is on the opposite side of the other end of the connecting circuit board FB that is connected to the display panel DP.

[0088] The main circuit board (MB) can provide image data, control signals, power voltage, etc., to the display panel (DP). The main circuit board (MB) can be a wiring board distinct from the connecting circuit board (FB), and can include active and passive components. The main circuit board (MB) can be flexible or rigid, and is not necessarily limited to any particular implementation.

[0089] The processor and / or memory, etc., can be located on the main circuit board MB. For example, when the display device 1 is used in a mobile communication terminal, the processor can be an application processor including a central processing unit, a graphics processing unit, and / or a modem, etc. The connecting circuit board FB can be bent so that the main circuit board MB can be positioned relative to the third-party DR3 on the rear surface of the display panel DP.

[0090] Display devices are evolving to reduce the non-display area to achieve narrower bezels, and to house numerous components, such as lines, within the non-display area to operate various functions of the display device. To this end, a method could be considered to reduce the area of ​​the pad region where panel pads are located, which is part of the non-display area.

[0091] Figure 4 This is an illustrative representation according to an embodiment. Figure 1 A plan view of the pad area.

[0092] Multiple panel pads (PPs) can be arranged on the substrate BSL in the pad region PA in a first direction DR1. Multiple panel pad groups, each including multiple panel pads (PPs), can be arranged in the pad region PA.

[0093] A panel pad group may include multiple panel pads (PPs) that receive one or more signals to be sent to the display area (DA). The panel pads (PPs) may be spaced apart from each other.

[0094] Panel pads PP can extend within the pad area PA (e.g., between the edge of the display panel DP and the display area DA). At least two of the multiple panel pads PP can be tilted without being parallel to each other. For example, panel pads PP can have different tilt angles relative to the second direction DR2.

[0095] The distance between a panel pad PP and the nearest other panel pad PP can be such that the distance between panel pad PPs near the display area DA is less than the distance between panel pad PPs on the edge of the display panel DP. For example, the distance between adjacent panel pad PPs can gradually increase in the direction away from the display area DA. The distance between a panel pad PP and the nearest other panel pad PP can be such that no short circuit occurs, at least between adjacent panel pad PPs.

[0096] Panel pads (PP) can have various shapes. For example, panel pads (PP) can be quadrilateral in shape, such as rectangular, trapezoidal, parallelogram, etc.

[0097] For example, some panel pads (PP) can have the same shape as each other. As another example, some panel pads (PP) can have the same length but different angles. As yet another example, some panel pads (PP) can have the same length but different widths.

[0098] In methods for reducing the area of ​​pad region PA, when the distance from one side of a panel pad PP to the side of another panel pad PP closest to that panel pad PP is called the pitch, a method for reducing the pitch can be designed.

[0099] For example, when the pitch between all panel pads (PP) within a panel pad group is the same, the pitch between panel pads (PP) in a specific panel pad group can be reduced. For example, the distance between panel pads (PP) in a specific panel pad group and / or the width of panel pads (PP) in a specific panel pad group can be reduced to reduce the area of ​​the pad region (PA).

[0100] When the pitch between panel pads (PP) of a specific panel pad group is reduced by a certain ratio, the distance between panel pads (PP) of the specific panel pad group and the width of panel pads (PP) of the specific panel pad group can be reduced by the same ratio.

[0101] For example, in the pad area PA, a first panel pad group PG1 and a second panel pad group PG2 can be arranged on the first direction DR1. The first panel pad group PG1 and the second panel pad group PG2 can each include a panel pad PP.

[0102] A first panel pad group PG1 may include first panel pads PP1 that are at a constant distance from each other, and a second panel pad group PG2 may include second panel pads PP2 that are at a constant distance from each other. A first distance d1, which is the distance between the first panel pads PP1, may differ from a second distance d2, which is the distance between the second panel pads PP2. For example, the first distance d1 may be smaller than the second distance d2.

[0103] The first panel pad PP1 can have a constant width relative to each other, and the second panel pad PP2 can also have a constant width relative to each other. However, the first width A1, which is the width of the first panel pad PP1, can be different from the second width A2, which is the width of the second panel pad PP2. For example, the first width A1 can be smaller than the second width A2.

[0104] For example, the pitch between first panel pads PP1 included in the first panel pad group PG1 may be smaller than the pitch between second panel pads PP2 included in the second panel pad group PG2.

[0105] Each panel pad PP can be connected to a line for a specific purpose to drive a specific function. The lines connected to the panel pad PP may include power lines for supplying power to the display device 1, signal lines for transmitting information to the pixels PX, touch lines for detecting touch input, backlight lines for controlling the backlight, ground lines for providing a common reference voltage, test lines for testing and diagnostics during the manufacturing process of the display device 1, etc.

[0106] Among the various functions used for different purposes, there may be functions that do not require relatively small resistance (e.g., they may be able to work correctly with higher resistance). Since low resistance is not required, it may be possible to connect to panel pads PP with a reduced pitch, and therefore no problem may occur despite the relative increase in resistance due to the reduced width of the panel pads PP.

[0107] For example, functions that do not require low resistance can be driven by connecting a line to a panel pad group consisting of panel pads (PPs) with narrow spacing and small width. For instance, power-related functions may require relatively low resistance, while touch-related functions may not. Therefore, compared to power lines, touch lines can be electrically connected to panel pads (PPs) with reduced spacing and / or reduced width.

[0108] For example, a touch line can be electrically connected to a first panel pad PP1 included in a first panel pad group PG1, the first panel pad PP1 having a smaller pitch than the pitch between second panel pads PP2 included in a second panel pad group PG2.

[0109] At least two panel pads PP can be positioned within a pad area PA and tilted without being parallel to each other. In this case, the upper ends of the panel pads PP in a second direction DR2 perpendicular to the first direction DR1 can be collinearly positioned in the first direction DR1. Each panel pad PP can have a different degree of tilt in the second direction DR2, but the opposite ends of the panel pads PP can be collinearly positioned in the first direction DR1.

[0110] The first panel pad group PG1 and the second panel pad group PG2 may each have a width in the first direction DR1, and this width may differ between regions. For example, one end of the first panel pad group PG1 and the second panel pad group PG2 near the display area DA may have a smaller width than the other end of the first panel pad group PG1 and the second panel pad group PG2 near the edge of the display panel DP. For example, the width of the first panel pad group PG1 and the second panel pad group PG2 may gradually increase in the direction away from the display area DA.

[0111] Keys may also be included between panel pad groups to determine whether panel pads PP are correctly positioned, correctly connected to connection pads FP on the connection board FB, or correctly connected to the integrated circuit (IC). Keys can be located between the edge of the pad area PA and the outermost panel pad PP.

[0112] Figure 5 This is an illustrative representation according to another embodiment. Figure 1 A plan view of the pad area.

[0113] Multiple panel pads (PPs) can be arranged on the substrate BSL in the pad region PA in a first direction DR1. Multiple panel pad groups, each including multiple panel pads (PPs), can be arranged in the pad region PA.

[0114] For example, in the pad area PA, a first panel pad group PG1, a second panel pad group PG2, and a third panel pad group PG3 can be arranged on the first direction DR1. Each of the first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 can include a panel pad PP. In the pad area PA, the first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 can be arranged sequentially on the first direction DR1.

[0115] The first panel pad group PG1 may include first panel pads PP1 spaced apart from each other at a constant distance, the second panel pad group PG2 may include second panel pads PP2 spaced apart from each other at a constant distance, and the third panel pad group PG3 may include third panel pads PP3 spaced apart from each other at a constant distance.

[0116] The first distance d1, which is the distance between the first panel pads PP1, can be different from the second distance d2, which is the distance between the second panel pads PP2. The third distance d3, which is the distance between the third panel pads PP3, can be different from the first distance d1 and / or the second distance d2. For example, the first distance d1 and the third distance d3 can be smaller than the second distance d2. The first distance d1 and the third distance d3 can be the same as or different from each other.

[0117] The first panel pad PP1 can have a constant width relative to each other, the second panel pad PP2 can have a constant width relative to each other, and the third panel pad PP3 can have a constant width relative to each other.

[0118] However, the first width A1, which is the width of the first panel pad PP1, can be different from the second width A2, which is the width of the second panel pad PP2. The third width A3, which is the width of the third panel pad PP3, can be different from the first width A1 and / or the second width A2. For example, the first width A1 and the third width A3 can be smaller than the second width A2. The first width A1 and the third width A3 can be the same as or different from each other.

[0119] For example, the pitch between the first panel pads PP1 included in the first panel pad group PG1 and the pitch between the third panel pads PP3 included in the third panel pad group PG3 can be smaller than the pitch between the second panel pads PP2 included in the second panel pad group PG2.

[0120] Each panel pad PP can be connected to a line for a specific purpose to drive a specific function. The lines connected to the panel pad PP may include power lines for supplying power to the display device 1, signal lines for transmitting information to the pixels PX, touch lines for detecting touch input, backlight lines for controlling the backlight, ground lines for providing a common reference voltage, test lines for testing and diagnostics during the manufacturing process of the display device 1, etc.

[0121] Relative to each other, lines that do not require low resistance can be connected to a group of panel pads, including panel pads PP with narrow spacing and small width. For example, the panel pad PP to which a touch line is connected can have a smaller spacing between panel pads PP and / or a smaller width of panel pad PP than the panel pad PP to which a power line is connected.

[0122] For example, the touch line can be electrically connected to a first panel pad PP1 included in a first panel pad group PG1 and a third panel pad PP3 included in a third panel pad group PG3, wherein the first panel pad PP1 and the third panel pad PP3 have a smaller pitch than the pitch between the second panel pad PP2 included in the second panel pad group PG2.

[0123] At least two panel pads PP can be positioned within a pad area PA and tilted without being parallel to each other. For example, the upper ends of the panel pads PP in a second direction DR2 perpendicular to the first direction DR1 can be collinearly positioned in the first direction DR1. Each panel pad PP can have a different tilt angle in the second direction DR2, but the opposite ends of the panel pads PP can be collinearly positioned in the first direction DR1.

[0124] The first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 may each have a width in the first direction DR1, and this width may vary between regions. For example, the ends of the first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 near the display area DA may have a smaller width than the other ends of the first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 near the edge of the display panel DP. For example, the width of the first panel pad group PG1, the second panel pad group PG2, and the third panel pad group PG3 may gradually increase in the direction away from the display area DA.

[0125] Keys may also be included between panel pad groups to determine whether the panel pads PP are correctly positioned, correctly connected to the connection pads FP of the connection board FB, or correctly connected to the IC. The keys can be located between the edge of the pad area PA and the outermost panel pad PP.

[0126] The first panel pad PP1 of the first panel pad group PG1 and the third panel pad PP3 of the third panel pad group PG3 are described and shown as having a smaller pitch, distance and width than the second panel pad PP2 of the second panel pad group PG2, but these are examples and this disclosure is not necessarily limited thereto.

[0127] For example, as another example, the second panel pad PP2 of the second panel pad group PG2 is described and shown as having a smaller pitch, distance and width than the first panel pad PP1 of the first panel pad group PG1 and the third panel pad PP3 of the third panel pad group PG3, making it possible to make a variety of designs.

[0128] Figure 6 This is an illustrative representation of the display device in... Figure 1 A plan view of a portion of the pad area, where the panel pads and connection pads are separated from each other, and Figure 7 This is an illustrative representation of the display device in... Figure 1 A partial plan view of the pad area.

[0129] Each panel pad PP can be electrically connected to each connection pad FP of the corresponding connection board FB to receive signals. The panel pad PP can transmit the signals received from the connection board FB to the pixel PX, etc., via lines. For example, multiple lines can extend from the display area DA and connect to each of the multiple panel pads PP. The connection board FB can be electrically connected to the panel pad PP.

[0130] The display device 1 may further include a connection circuit board FB having a plurality of connection pads FP arranged on the first direction DR1. On the connection circuit board FB, a first connection pad group FG1 and a second connection pad group FG2 arranged on the first direction DR1 may be provided.

[0131] The first connection pad group FG1 may include first connection pads FP1 that are at a constant distance from each other, and the second connection pad group FG2 may include second connection pads FP2 that are at a constant distance from each other.

[0132] For example, a first panel pad group PG1 and a second panel pad group PG2, each including panel pads PP, can be disposed in the pad area PA of the display panel DP. Each of the first panel pad group PG1 and the second panel pad group PG2 can be electrically connected to a corresponding connection pad group (i.e., the first connection pad group FG1 and the second connection pad group FG2). For example, the first connection pad group FG1 can be electrically connected to the first panel pad group PG1, and the second connection pad group FG2 can be electrically connected to the second panel pad group PG2. This allows the display panel DP and the connection circuit board FB to be electrically connected to each other.

[0133] The connection circuit board FB may include a first connection pad group FG1 and a second connection pad group FG2 on its surface. The shapes of the first connection pad group FG1 and the second connection pad group FG2 may correspond to the shapes of the first panel pad group PG1 and the second panel pad group PG2.

[0134] The first connection pad group FG1 and the second connection pad group FG2 may have a width in the first direction DR1, and the widths of the first connection pad group FG1 and the second connection pad group FG2 may differ between regions. For example, the width of the first connection pad group FG1 and the second connection pad group FG2 near the display panel DP may be smaller than the width of the first connection pad group FG1 and the second connection pad group FG2 near the main circuit board MB, and for example, the width of the first connection pad group FG1 and the second connection pad group FG2 may gradually decrease towards the edge of the connection circuit board FB near the display panel DP.

[0135] The first connection pad group FG1 and the second connection pad group FG2 may each include multiple connection pads FP arranged on the first direction DR1. The connection pads FP can be paths used to transmit signals from the connection board FB to the display panel DP.

[0136] The first connection pad group FG1 and the second connection pad group FG2 correspond to the first panel pad group PG1 and the second panel pad group PG2, respectively, and each connection pad FP can correspond to each panel pad PP. For example, a panel pad PP can be connected to a connection pad FP and can be connected without overlapping with another panel pad PP.

[0137] Each of the connection pads FP can overlap with a panel pad PP in at least one region. In some embodiments, a first connection pad FP1, which is a connection pad FP of a first connection pad group FG1, can be electrically connected to a first panel pad PP1 of a first panel pad group PG1, overlapping in at least one region, and a second connection pad FP2, which is a connection pad FP of a second connection pad group FG2, can be electrically connected to a second panel pad PP2 of a second panel pad group PG2, overlapping in at least one region, the second panel pad PP2 of a second panel pad group PG2.

[0138] Since one connection pad FP corresponds to one panel pad PP, the connection pads FP can be spaced apart from each other, just like the panel pads PP. The connection pads FP can extend along the second direction DR2. At least two of the multiple connection pads FP can be tilted without being parallel to each other. For example, the connection pads FP can have different tilt angles relative to the second direction DR2.

[0139] Connection pads (FPs) can have various shapes. For example, connection pads (FPs) can be quadrilateral (e.g., rectangular, trapezoidal, parallelogram) or similar shapes.

[0140] At least two of the multiple connection pads FP can be disposed on the connection board FB and tilted without being parallel to each other. For example, the upper ends of the connection pads FP in a second direction DR2 perpendicular to the first direction DR1 can be collinearly positioned in the first direction DR1. Each connection pad FP can have a different tilt in the second direction DR2, but the opposite ends of the connection pads FP can be collinearly positioned in the first direction DR1.

[0141] The connection pad FP can transmit various signals generated in the display device 1 from the connection circuit board FB to the display panel DP via the panel pad PP. For example, signals generated on the main circuit board MB can be transmitted to the connection circuit board FB via signal lines, and then transmitted to the display panel DP via the connection pad FP and the panel pad PP. The connection pad FP can electrically connect the connection circuit board FB to the panel pad PP.

[0142] Each of the multiple connection pads FP can overlap with a corresponding panel pad PP in at least one area. Each of the multiple connection pads FP in a connection pad group can be electrically connected to each of the multiple panel pads PP in a corresponding panel pad group.

[0143] The fourth distance d4, which is the distance between the first connection pads FP1 belonging to the first connection pad group FG1, can correspond to the first distance d1, which is the distance between the first panel pads PP1 belonging to the first panel pad group PG1. The fourth distance d4 can be equal to the first distance d1, or it can have a difference that is at least sufficient to allow a one-to-one correspondence between the first connection pads FP1 and the first panel pads PP1.

[0144] The fifth distance d5, which is the distance between the second connection pads FP2 belonging to the second connection pad group FG2, can correspond to the second distance d2, which is the distance between the second panel pads PP2 belonging to the second panel pad group PG2. The fifth distance d5 can be equal to the second distance d2, or it can have a difference that is at least sufficient to allow for a one-to-one correspondence between the second connection pads FP2 and the second panel pads PP2.

[0145] Since the first distance d1 between the first panel pads PP1 and the second distance d2 between the second panel pads PP2 are different from each other, the fourth distance d4 corresponding to the first distance d1 can be different from the fifth distance d5 corresponding to the second distance d2.

[0146] The first panel pads PP1 belonging to the first panel pad group PG1 can all have the same distance from each other, and correspondingly, the first connection pads FP1 belonging to the first connection pad group FG1 can also have the same distance from each other.

[0147] The second panel pads PP2 belonging to the second panel pad group PG2 can all have the same distance from each other, and correspondingly, the second connection pads FP2 belonging to the second connection pad group FG2 can also have the same distance from each other.

[0148] The fourth width A4, which is the width of the first connection pad FP1 belonging to the first connection pad group FG1, can correspond to the first width A1, which is the width of the first panel pad PP1 belonging to the first panel pad group PG1. The fourth width A4 can be equal to the first width A1, or it can have a difference that is at least sufficient to allow a one-to-one correspondence between the first connection pad FP1 and the first panel pad PP1.

[0149] The fifth width A5, which is the width of the second connection pad FP2 belonging to the second connection pad group FG2, can correspond to the second width A2, which is the width of the second panel pad PP2 belonging to the second panel pad group PG2. The fifth width A5 can be equal to the second width A2, or it can have a difference that is at least sufficient to allow for a one-to-one correspondence between the second connection pad FP2 and the second panel pad PP2.

[0150] Since the first width A1, which is the width of the first panel pad PP1, is different from the second width A2, which is the width of the second panel pad PP2, the fourth width A4, which corresponds to the first width A1, can be different from the fifth width A5, which corresponds to the second width A2.

[0151] The first panel pads PP1 belonging to the first panel pad group PG1 can all have the same width as each other, and correspondingly, the first connection pads FP1 belonging to the first connection pad group FG1 can also have the same width as each other.

[0152] The second panel pads PP2 belonging to the second panel pad group PG2 can all have the same width as each other, and correspondingly, the second connection pads FP2 belonging to the second connection pad group FG2 can also have the same width as each other.

[0153] The first connection pad group FG1 can correspond to the first panel pad group PG1. The first connection pad FP1 of the first connection pad group FG1 can overlap with the first panel pad PP1 of the first panel pad group PG1.

[0154] The width of the first connection pad group FG1 can be the same as the width of the first panel pad group PG1. The first connection pad group FG1 and the first panel pad group PG1 do not need to overlap to achieve a precise match, and they may need to overlap such that the first connection pad FP1 and the first panel pad PP1 are connected one-to-one, and therefore the first connection pad group FG1 can be slightly misaligned from the position of the first panel pad group PG1 in any direction, up, down, left, or right, to the extent that the respective panel pads PP and connection pads FP do not have a short circuit.

[0155] The second connection pad group FG2 can correspond to the second panel pad group PG2. The second connection pad FP2 of the second connection pad group FG2 can overlap with the second panel pad PP2 of the second panel pad group PG2.

[0156] The width and length of the second connection pad FP2 can be the same as or different from the width and length of the second panel pad PP2, such that a second panel pad PP2 overlaps with a second connection pad FP2.

[0157] When a panel pad PP overlaps with a connection pad FP, the center of the panel pad PP can coincide with the center of the connection pad FP. When the centers of the panel pad PP and the connection pad FP do not coincide, the distance from the panel pad PP to the nearest panel pad PP, without overlapping with the connection pad FP, can be a distance that does not cause a short circuit between the connection pad FP and the panel pad PP. For example, the distance between the connection pad FP and the panel pad PP can be at least 35 μm without causing a short circuit.

[0158] Based on the pitch (which is the distance from one side of a panel pad PP to the side of the next panel pad PP closest to it) or equipment process conditions, the optimal overlap area between the panel pad PP and the connecting pad FP, as well as the distance between the connecting pad FP and the adjacent panel pad PP, can vary, and therefore, the ratio of the width of the panel pad PP to the distance between the panel pad PPs can be adjusted.

[0159] For example, when the pitch is 100 μm, the ratio of the width of the panel pad PP to the distance between panel pad PPs can be 60:40. As another example, when the pitch is 70 μm, the ratio of the width of the panel pad PP to the distance between panel pad PPs can be 35:40 or 40:35. However, this disclosure is not necessarily limited to the above examples, and the ratio of the width of the panel pad PP to the distance between panel pad PPs can be adjusted by taking into account the optimal overlap area between the panel pad PP and the connection pad FP and the distance between the connection pad FP and the adjacent panel pad PP.

[0160] Despite Figure 7 The diagram shows and describes a first panel pad group PG1 and a second panel pad group PG2 disposed in the pad area PA and connected to the first connection pad group FG1 and the second connection pad group FG2 of the connection circuit board FB. However, this is only an example, and a third panel pad group PG3 may also be disposed in the pad area PA. Therefore, the third connection pad group FG3 of the connection circuit board FB may be formed to correspond to the third panel pad group PG3 and electrically connected to the third panel pad group PG3.

[0161] refer to Figure 7 As the panel pads PP of the display panel DP and the connection pads FP of the connection circuit board FB overlap and make contact with each other, the display panel DP and the connection circuit board FB can be electrically connected to each other. The scheme for connecting the panel pads PP to the connection pads FP will be described in detail below.

[0162] Figure 8 It is an illustrative representation of along Figure 1 A sectional view of the section cut by line II-II', and Figure 9 It is an illustrative representation of along Figure 1 A sectional view of the section cut by line III-III'.

[0163] Each of the multiple panel pads PP located in the non-display area NDA of the display panel DP can overlap with the connection pads FP located on the surface of the connection circuit board FB, thereby electrically connecting the connection circuit board FB to the display panel DP.

[0164] For example, refer to Figure 8 The panel pads PP and connecting pads FP, which are electrically connected to each other and overlap, have the same width, and the widths of the panel pads PP and connecting pads FP can be connected to each other simultaneously in a corresponding manner. The widths of the panel pads PP and connecting pads FP can be different from each other, and the widths of the panel pads PP and connecting pads FP can not correspond to each other, so that the opposite side surfaces of the panel pads PP and connecting pads FP can be imprecisely matched.

[0165] The panel pads PP and the connection pads FP can have appropriate widths to achieve structural stability in which they are connected to each other in an overlapping manner and to each other in a way that adequately supports the connection board FB.

[0166] refer to Figure 9 The display panel DP may include a display area DA located in the middle of the display panel DP and non-display areas NDA located on both sides of the display area DA.

[0167] The display panel DP may include a substrate BSL, a pixel layer PXL, and a packaging layer TFE laminated on the third-direction DR3 in cross-section.

[0168] The substrate BSL can be a base layer on which the pixel layer PXL is formed. The substrate BSL can be a single layer or can include multiple insulating layers. The substrate BSL can be at least any one of glass substrate, plastic substrate, film, and laminate including multiple organic films and / or inorganic films, but this disclosure is not necessarily limited to any one embodiment.

[0169] The substrate BSL can include driving elements, signal lines, etc. of the pixel PX. Therefore, the substrate BSL can have a laminated structure with multiple conductive layers and multiple organic and / or inorganic films.

[0170] The pixel layer PXL can be disposed on the substrate BSL. The pixel layer PXL can be electrically connected to the driving elements and signal lines of the substrate BSL. The pixel layer PXL can include the display elements among the aforementioned pixels PX. For example, when the display panel DP is an organic light-emitting display panel, the pixel layer PXL can include an organic light-emitting layer. The display area DA can correspond to the area where the pixel layer PXL is disposed.

[0171] The encapsulation layer TFE can be placed on the pixel layer PXL to cover it. The encapsulation layer TFE protects the pixel layer PXL. The encapsulation layer TFE can cover the side surfaces of the pixel layer PXL. Depending on the type of display panel DP, the encapsulation layer TFE can be omitted or replaced with another display substrate.

[0172] The connection circuit board FB can be placed in the pad area PA of the display panel DP to connect the main circuit board MB to the display panel DP. The connection circuit board FB can be located on one side of the display panel DP extending in the second direction DR2.

[0173] For example, the connection circuit board FB can be provided as a single component. As another example, multiple connection circuit boards FB can be provided and arranged on the first direction DR1, and are not necessarily limited to any one implementation.

[0174] The display device 1 described above may include a group of panel pads PP, wherein the panel pads PP have different pitches or distances and different widths. By reducing the pitch or distance between the panel pads PP and the width of the panel pads PP, the area of ​​the pad region PA can also be reduced. The panel pads PP can also be arranged proportionally to the reduced area of ​​the pad region PA, and lines, circuits, etc., capable of performing other functions can also be designed to achieve multiple functional designs.

[0175] As the area of ​​the panel pads (PP) decreases, the area of ​​the corresponding connecting circuit boards (FB) can also be reduced, thereby reducing costs.

[0176] The reduced pad area PA can ensure additional space and reduce the thickness of the display device 1, allowing for various structural designs.

[0177] The aforementioned display device 1 can be applied to various products that display images. For example, display device 1 can be applied to various electronic devices such as mobile phones, tablet computers and laptop computers, televisions, computer monitors, digital cameras, camcorders, portable game consoles, vehicle displays, head-up displays, wearable displays, augmented reality or virtual reality displays, digital billboards, video walls, etc.

[0178] Figure 10 This is a block diagram of an electronic device according to an embodiment of the present disclosure. Figure 10 An example is shown, and depending on the purpose and design requirements of the electronic device 1000, the electronic device 1000 may optionally include... Figure 10 One or more of the multiple components shown.

[0179] The electronic device 1000 can output various information through the display module 1400 within the operating system. The display module 1400 may correspond to the display device 1 of this embodiment, or may correspond to at least a portion of it.

[0180] The touch detection unit or touch electrode of the display module 1400 may be included in the sensor module 1610, and as described below, the sensor module 1610 may be included in the display module 1400 or integrally formed with the display module 1400.

[0181] When the processor 1100 runs an application stored in the memory 1200, the display module 1400 can provide application information to the user through the display panel DP.

[0182] The processor 1100 can obtain external input through the input module 1300 or the sensor module 1610, and run the application corresponding to the external input. For example, when a user selects the camera icon displayed on the display panel DP, the processor 1100 can obtain user input through the input sensor 1612 (e.g., the touch detection unit in the above embodiment) and activate the camera module 1710. The processor 1100 can transmit the image data corresponding to the captured image obtained by the camera module 1710 to the display module 1400. The display module 1400 can display the image corresponding to the captured image through the display panel DP.

[0183] As another example, when personal information authentication is performed in display module 1400, fingerprint sensor 1611 can obtain input fingerprint information as input data. Processor 1100 can compare the input data obtained by fingerprint sensor 1611 with authentication data stored in memory 1200 and run the application based on the comparison result. Display module 1400 can display information about the logic running according to the application via display panel DP.

[0184] As another example, when a music stream icon displayed on display module 1400 is selected, processor 1100 can obtain user input via input sensor 1612 and activate the music stream application stored in memory 1200. When a music run command is entered in the music stream application, processor 1100 can activate audio output module 1630 to provide the user with audio information corresponding to the music run command.

[0185] The operation of the electronic device 1000 has been briefly described so far. The configuration of the electronic device 1000 will be described in detail below. Some of the components of the electronic device 1000 described below can be integrated and provided as a single component, or a single component can be provided separately as two or more components.

[0186] refer to Figure 10 The electronic device 1000 can communicate with an external electronic device 1020 via a network (e.g., a short-range wireless communication network or a long-range wireless communication network). According to an embodiment, the electronic device 1000 may include a processor 1100 that operates by running at least one program, a memory 1200 that stores at least one program, an input module 1300, a display module 1400, and a power module 1500 that supplies power to the display module 1400. The processor 1100 can control the input module 1300 to obtain data and can control the display module 1400 to visually display the data.

[0187] The electronic device 1000 may further include an embedded module 1600 and an external module 1700. The embedded module 1600 may include a sensor module 1610 for detecting input and generating data corresponding to that input, an antenna module 1620 for sending or receiving data or power from the external electronic device 1020, and an audio output module 1630 for controlling the processor 1100 to audibly output data. The external module 1700 may include a camera module 1710 for capturing still and / or moving images, an optical module 1720 for outputting light, and a communication module 1730 for sending or receiving data between the electronic device 1000 and the external electronic device 1020.
