Description

Technical Field

[0001] This disclosure relates to a display device for displaying images. Background Technology

[0002] Display devices are used in various electronic devices such as TVs, mobile phones, laptops, and tablets. Research is underway to develop display devices that are high-resolution, large-sized, thin, lightweight, and low-power.

[0003] Display devices may include liquid crystal display devices (LCD), plasma display panel devices (PDP), field emission display devices (FED), electrowetting display devices (WED), and electroluminescent display devices (ELDD).

[0004] The display device includes a display panel and a driving board. The display panel includes a display area for displaying an image, and the driving board drives the display panel. The display panel may include two substrates facing each other, a polarizing material or a light-emitting material disposed between the two substrates, and a thin-film transistor array defining multiple pixel areas arranged in the display area and driving each pixel area. The thin-film transistor array may include multiple thin-film transistors corresponding to the multiple pixel areas and multiple signal lines connected to the multiple thin-film transistors. The driving board is connected to the signal lines of the thin-film transistor array and provides driving signals corresponding to the image to the multiple signal lines.

[0005] In this regard, each signal line is made of a conductive material and has a predetermined line resistance. The line resistance is proportional to the length of the signal line and to the number of pixel areas corresponding to each line.

[0006] In other words, when a display device is implemented at high resolution, each signal line arranged in a relatively wide display area has a relatively long length, so there is a limit to how much line resistance can be reduced.

[0007] Furthermore, when the display device is implemented at a high resolution, the number of pixel areas connected to each signal line is relatively large, so the reduction in line resistance is limited.

[0008] Therefore, it is difficult to manufacture display devices that can achieve high resolution and large screen size at the same time. Summary of the Invention

[0009] The summary provides a simplified description of the selected concepts further described in the detailed embodiments below. This summary is not intended to identify all key or essential features of the claimed subject matter, nor is it intended to be used alone to help determine the scope of the claimed subject matter.

[0010] The purpose of this disclosure is to provide a display device that can achieve high resolution and also has a large screen.

[0011] The purposes of this disclosure are not limited to those described above. Other purposes and advantages of this disclosure not mentioned above may be understood from the following description and will become clearer from embodiments of this disclosure. Furthermore, it will be readily understood that the purposes and advantages of this disclosure may be achieved by the features disclosed in the claims and combinations thereof.

[0012] An example of this disclosure provides a display device including a plurality of segmented display units arranged in a matrix, and a front display unit disposed on the plurality of segmented display units.

[0013] The front display unit includes: multiple transmissive areas, each corresponding to a main display area of ​​a multiple segmented display unit; and a supplementary display area, which corresponds to a separation area between the main display areas of adjacent segmented display units among the multiple segmented display units.

[0014] The resolution achieved by the supplementary display area of ​​the front display unit is lower than the resolution achieved by the main display area of ​​each segmented display unit.

[0015] The main display area of ​​each segmented display unit can be visually identified through the transmissive area of ​​the front display unit.

[0016] Because of the supplementary display area of ​​the front display unit, the dividing areas between the main display areas of adjacent segmented display units can be prevented from being visible to the user. Therefore, the display device does not display the image signal in a segmented manner that divides it into multiple segmented display units, but displays the image signal as a whole, so that the image signal can be visually recognized by the user as a whole.

[0017] Therefore, display devices can overcome the limitations of line resistance and achieve both large screen size and high resolution.

[0018] Each segmented display unit also includes a bottom signal line. The front display unit also includes a front signal line. The front signal line can be formed with a different pattern than the bottom signal line. Alternatively, the spacing between the front signal lines can vary based on a predefined length. This prevents moiré defects caused by overlap between the bottom and front signal lines.

[0019] A display device according to one embodiment of the present disclosure includes a plurality of segmented display units and a front display unit disposed on the plurality of segmented display units. The front display unit includes a plurality of transmissive areas corresponding to the plurality of segmented display units, and a supplementary display area corresponding to the partition area between the main display areas of adjacent segmented display units among the plurality of segmented display units.

[0020] Therefore, multiple segmented images displayed on multiple segmented display units can be visually identified through the transmission area of ​​the front display unit, while the discontinuity between adjacent segmented images in multiple segmented images can be eliminated through the supplementary display area of ​​the front display unit.

[0021] As a result, the display device can achieve both high resolution and a large screen size, while preventing image quality degradation.

[0022] In addition to the effects described above, the specific effects of this disclosure will be described together with the detailed description of how this disclosure is implemented. Attached Figure Description

[0043] In the following, preferred embodiments of the color filter substrate according to the present disclosure and the in-cell touch display device including the color filter substrate will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

[0044] In the following description, a display device according to one embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0045] Figure 1 and Figure 2 This is a diagram illustrating a display device according to one embodiment of the present disclosure. Figure 3 It shows from Figure 2 The image processor provides several examples of segmented images. Figure 4 It shows Figure 1 The diagram for each display unit. Figure 5 It shows the relationship with Figure 4 A diagram showing an example of the equivalent circuit corresponding to the pixel area.

[0046] like Figure 1 As shown, a display device 100 according to one embodiment of the present disclosure includes a plurality of segmented display units 110 arranged in a matrix, and a front display unit 120 disposed on the plurality of segmented display units 110 and having a width corresponding to the total width of the plurality of segmented display units 110.

[0047] Multiple segmented display units 110 are arranged in a matrix. In one example, such as Figure 1 As shown, multiple segmented display units 110 can be arranged in a 2×2 matrix. However, this is only an example. Multiple segmented display units 110 can also be arranged in an a×b matrix (where one of a and b is a natural number greater than 1, and the other is a natural number equal to or greater than 1). The number of columns and rows in the matrix of multiple segmented display units 110 can be varied, allowing the shape corresponding to the arrangement of the multiple segmented display units 110 to be changed.

[0048] Each segmented display unit 110 includes a main display area MDA that emits light for image display.

[0049] Each segmented display unit 110 may also include a main border area MBA disposed outside the main display area MDA and surrounding the main display area MDA.

[0050] Due to the spacing corresponding to the main border area MBA between adjacent segmented display units 110 among the plurality of segmented display units 110, a predetermined separation area SA is defined between the main display areas MDA of two adjacent segmented display units 110 among the plurality of segmented display units 110.

[0051] In one example, when multiple segmented display units 110 are in close contact with each other, the separation area between the main display areas MDA of two adjacent segmented display units 110 corresponds to the sum of the main border areas MBA of the two adjacent segmented display units 110.

[0052] Since no light is emitted from the separation area between the main display areas (MDAs) of adjacent segmented display units 110, the multiple segmented display units 110 can be visually identified as easily distinguishable tiles. In this case, the images displayed from the multiple segmented display units 110 can be visually identified in a segmented manner (i.e., in a segmented tile manner) rather than as a whole. Therefore, the improvement in display quality is limited.

[0053] To address this problem, a display device 100 according to one embodiment of the present disclosure includes a front display unit 120, which covers the separation area between the main display areas MDA of adjacent segmented display units among a plurality of segmented display units 110.

[0054] The front display unit 120 is disposed on the top surface of the plurality of segmented display units 110. In this regard, the direction toward the top surface is the emission direction of light from each segmented display unit 110. That is, light from each segmented display unit 110 is emitted to the outside through the front display unit 120.

[0055] The front display unit 120 may include: a plurality of transmissive areas TA, which correspond to the main display areas MDA of the plurality of segmented display units 110; and a supplementary display area SDA, which corresponds to the separation area between the main display areas MDA of adjacent segmented display units 110.

[0056] The supplementary display area SDA emits light for image display and covers the separation area between the main display areas MDA of the multiple segmented display units 110 that are adjacent to each other.

[0057] In one example, such as Figure 1 As shown, when multiple segmented display units 110 are arranged in a 2×2 matrix, the supplementary display area SDA can be cross-shaped.

[0058] Although not shown separately, when multiple segmented display units are arranged in a 1×b matrix, the supplementary display area SDA can consist of b-1 straight line regions that extend parallel to each other and are spaced apart from each other.

[0059] That is, the supplementary display area SDA can be implemented in any form, as long as the supplementary display area SDA covers the separation area between the main display areas MDA of adjacent segmented display units 110 among the multiple segmented display units 110.

[0060] Due to the supplementary display area SDA of the front display unit 120, the separation area between the main display areas MDA of adjacent segmented display units 110 may not be visible to external users.

[0061] Multiple transmissive areas TA overlap with the main display areas MDA of multiple segmented display units 110. That is, the number of transmissive areas TA included in the front display unit 120 is equal to the number of segmented display units 110.

[0062] Each transmission zone TA is designed to transmit light emitted from the main display zone MDA of each segmented display unit 110.

[0063] As described above, a display device 100 according to one embodiment of the present disclosure includes a front display unit 120 disposed on the top surface of a plurality of segmented display units 110. The front display unit 120 can transmit light emitted from the plurality of segmented display units 110 arranged in a matrix, and can cover the separation areas between the main display areas (MDAs) of adjacent segmented display units 110. That is, each of the plurality of segmented display units 110 can display each segmented image in each of its main display areas (MDAs). The front display unit 120 can display an image corresponding to the gaps between the segmented images in a supplementary display area (SDA), so that the segmented images can be displayed in a whole form rather than in a segmented mosaic form.

[0064] Since the front display unit 120 corresponds to a combination of multiple segmented display units 110, each segmented display unit 110 has a smaller size than the front display unit 120. Therefore, even when the segmented display unit 110 achieves a higher resolution than the front display unit 120, the segmented display unit 110 is less affected by problems caused by line resistance.

[0065] Since the front display unit 120 is larger than each segment display unit 110, there are limitations to achieving high resolution due to line resistance. That is, the supplementary display area SDA of the front display unit 120 can achieve a lower resolution than the main display area MDA of the segment display unit 110.

[0066] However, the supplementary display area SDA of the front display unit 120 is designed to display an image corresponding to the gap between the segmented images displayed on the main display area MDA of the adjacent segmented display units 110. Therefore, the fact that the supplementary display area SDA of the front display unit 120 achieves a lower resolution than the main display area MDA may not be easily recognized by the user.

[0067] Therefore, the display device 100 according to one embodiment of this disclosure can achieve a high resolution and a larger screen size. Thus, it has the advantage of expanding its application range.

[0068] In addition, such as Figure 2 As shown, the display device 100 according to one embodiment of the present disclosure may further include an image processor that provides each of the segmented image signals to each of the plurality of segmented display units 110 and the front display unit 120.

[0069] The image processor 130 can generate multiple segmented image signals corresponding to multiple segmented display units 110 (110-1, 110-2, ..., 110-n, where n is a natural number of 3 or greater) and the front display unit 120 based on external image signals.

[0070] That is, the image processor 130 can segment the external image signal based on the arrangement of multiple segmented display units 110 (110-1, 110-2, ..., 110-n, where n is a natural number of 3 or greater) and the front display unit 120, thereby generating segmented image signals corresponding to the multiple segmented display units 110 (110-1, 110-2, ..., 110-n, where n is a natural number of 3 or greater) and the front display unit 120.

[0071] In one example, such as Figure 1As shown, when the display device 100 includes four segmented display units 110 arranged in a 2×2 matrix, the image processor 130 can generate five segmented image signals corresponding to the four segmented display units 110 and a single front display unit 120.

[0072] That is, such as Figure 3 As shown, Figure 2 The image processor 130 of the display device 100 shown can segment the external image signal IMAGE based on the arrangement of four segmented display units 110 (110-1, 110-2, 110-3 and 110-4) and the front display unit 120 to generate a first segmented image signal to a fourth segmented image signal DI (DI1, DI2, DI3 and DI4) corresponding to the four main display areas MDA of the four segmented display units 110 arranged in a 2×2 matrix, and a fifth segmented image signal DI5 corresponding to the supplementary display area SDA of the front display unit 120.

[0073] Therefore, the multiple segmented display units 110 can respectively display the first to fourth segmented image signals DI1, DI2, DI3 and DI4 in their main display area MDA, while the front display unit 120 can display the fifth segmented image signal DI5 in its supplementary display area SDA. In this way, the external image signal IMAGE can be displayed in a holistic manner.

[0074] In one example, each of the plurality of segmented display units 110 and front display units 120 disposed in the display device 100 may include a display panel and a driver for driving the display panel.

[0075] That is, such as Figure 4 As shown, each display unit DU ( Figure 1 and Figure 2 110 and 120) include: a display panel DP, the display panel DP including signal lines GL and DL defining a plurality of pixel areas PA in a display area AA; and drivers TC, GL-D and DL-D, the drivers TC, GL-D and DL-D providing drive signals to the signal lines GL and DL of the display panel.

[0076] Each pixel area (PA) of a display panel (DP) emits light corresponding to one color. Two or more adjacent pixel areas (PAs) corresponding to different colors can constitute a unit pixel that emits light of various colors. That is, a unit pixel can display various colors via a combination of light beams emitted from two or more adjacent pixel areas (PAs) that realize a single unit pixel.

[0077] The display panel DP includes: a gate line GL, which provides a scan signal SCAN to select the horizontal line in which the recording data signal VDATA is recorded; and a data line DL, which provides a data signal VDATA corresponding to the brightness of each pixel area PA. The horizontal line is composed of pixel areas arranged in a horizontal row among multiple pixel areas PA.

[0078] Furthermore, when the display panel DP has a structure including multiple light-emitting elements corresponding to multiple pixel areas PA, the display panel DP may also include a first driving power line and a second driving power line. Figure 3 The first driving power line and the second driving power line (VDL and VSL) respectively provide a first driving power supply VDD and a second driving power supply VSS for driving the light-emitting element.

[0079] The drivers TC, GL-D, and DL-D may include a gating line driver GL-D that provides a scan signal SCAN to the gating line GL of the display panel DP, a data line driver DL-D that provides a data signal VDATA to the data line DL of the display panel DP, and a timing controller TC for controlling the operating timing of the gating line driver GL-D and the data line driver DL-D.

[0080] The timing controller TC can rearrange the externally input digital video data RGB based on the resolution of the display area AA, and provide the rearranged digital video data RGB′ to the data line driver DL-D.

[0081] The timing controller TC can provide data control signals DDC for controlling the operating timing of the data line driver DL-D and gating control signals GDC for controlling the operating timing of the gating line driver GL-D, based on timing signals such as vertical synchronization signal Vsync, horizontal synchronization signal Hsync, dot clock signal DCLK, and data enable signal DES.

[0082] The GL-D gating line driver sequentially provides scan signals (SCAN) to multiple gating lines (GL) corresponding to multiple horizontal lines during a frame period based on the gating control signal (GDC).

[0083] That is, the gate line driver GL-D provides a scan signal SCAN to the gate line GL corresponding to each horizontal line during each horizontal period of each horizontal line in a frame period.

[0084] The data line driver DL-D converts the rearranged digital video data RGB′ into analog data voltages based on the data control signal DDC. Based on the rearranged digital video data RGB′, the data line driver DL-D provides the data line DL with a data signal VDATA corresponding to each pixel area PA of the horizontal line of the provided scan signal SCAN during each horizontal cycle.

[0085] Figure 5 An example of the equivalent circuit for each pixel area PA is shown when the display panel DP includes multiple light-emitting elements corresponding to multiple pixel areas PA.

[0086] like Figure 5 As shown, each pixel region PA may include an organic light-emitting element (OLED) and pixel circuits DT, ST, and Cst that provide driving signals to the OLED.

[0087] Pixel circuitry may include a driving thin-film transistor (DT), a switching thin-film transistor (ST), and a storage capacitor (Cst). However, this is merely an example. Alternatively, each pixel region PA may include pixel circuitry and may also include compensation circuitry (not shown) to compensate for degradation of at least one of the driving thin-film transistor (DT) or the organic light-emitting element (OLED). The compensation circuitry may include at least one thin-film transistor for sensing functions or for providing a reference power supply (not shown).

[0088] An organic light-emitting element (OLED) includes a first electrode and a second electrode (i.e., an anode and a cathode) and a light-emitting layer disposed between the first electrode and the second electrode. The light-emitting layer emits light based on a driving current between the first electrode and the second electrode. An OLED can have a multilayer stacked structure comprising two or more light-emitting layers.

[0089] The driving thin-film transistor DT can be connected in series to the organic light-emitting element OLED and can be positioned between the first driving power line VDL that provides the first driving power VDD and the second driving power line VSL that provides the second driving power VSS, wherein the potential of the second driving power VSS is lower than the potential of the first driving power VDD.

[0090] The switching thin-film transistor ST can be positioned between the data line DL that provides the data signal VDATA for each pixel region PA and the gate of the driving thin-film transistor DT, and connected to the data line and the gate.

[0091] The storage capacitor Cst can be positioned between the first node ND1 and the second node ND2. The first node ND1 refers to the contact point between the gate of the switching thin-film transistor ST and the driving thin-film transistor DT. The second node ND2 refers to the contact point between the driving thin-film transistor DT and the organic light-emitting element OLED.

[0092] In this pixel circuit, the switching thin-film transistor ST is turned on based on the scan signal SCAN of the gate line GL. The turned-on switching thin-film transistor ST allows the data signal VDATA of the data line DL to be supplied to the gate of the driving thin-film transistor DT and the storage capacitor Cst connected to the first node ND1.

[0093] The storage capacitor Cst is charged using the data signal VDATA provided to the first node ND1.

[0094] The driving thin-film transistor DT is turned on based on the data signal VDATA supplied to the first node ND1 and the charging voltage of the storage capacitor Cst. In this respect, the turned-on driving thin-film transistor DT can allow the driving current corresponding to the data signal VDATA to be supplied to the second node ND2 (i.e., the organic light-emitting element OLED).

[0095] Next, refer to Figures 6 to 15 The present disclosure will describe a segmented display unit 110 and a front display unit 120 provided in a display device 100 according to one embodiment of the present disclosure.

[0096] Figure 6 It shows Figure 1 A diagram showing an example of multiple segmented display units. Figure 7 It shows Figure 6 A diagram of an example of part A. Figure 8 It shows Figure 6 A diagram of part B, showing an example.

[0097] like Figure 6 As shown, multiple segmented display units 110-1, 110-2, 110-3, and 110-4 have the same size. In this respect, the sizes of the multiple segmented display units can be the same within a range of error that the user cannot visually discern.

[0098] Multiple segmented display units 110-1, 110-2, 110-3 and 110-4 are arranged in a matrix or side by side.

[0099] The edges of two adjacent segmented display units among the multiple segmented display units 110-1, 110-2, 110-3, and 110-4 may be spaced apart by a micro-gap. In this sense, the micro-gap is within a range that makes it difficult for the user to easily and intuitively detect. In one example, the micro-gap may be smaller than the width of the main border area MBA, or smaller than the width of the pixel area PA.

[0100] Alternatively, the edges of two adjacent segmented display units among the plurality of segmented display units 110-1, 110-2, 110-3, and 110-4 may contact each other. In this regard, adjacent segmented display units 110-1, 110-2, 110-3, and 110-4 may be fixed together by means of adhesive or the like. This reduces physical impact between adjacent segmented display units when vibration occurs due to movement or installation of the display device 100.

[0101] Figure 6 The diagram shows a first segmented display unit 110-1, a second segmented display unit 110-2, a third segmented display unit 110-3, and a fourth segmented display unit 110-4 arranged in a 2×2 matrix. However, this is merely an example. Multiple segmented display units 110-1, 110-2, 110-3, and 110-4 can be arranged in various planar shapes corresponding to the front display unit 120.

[0102] Each of the multiple segmented display units 110-1, 110-2, 110-3 and 110-4 may include a main display area MDA that emits light for image display and a main border area MBA that is outside the main display area MDA and surrounds the main display area MDA.

[0103] like Figure 7 As shown, each of the segmented display units 110-1 and 110-2 includes a plurality of main pixel areas (MPAs) arranged in a matrix in the main display area (MDA).

[0104] The separation area SA between the main display areas MDA of the first segmented display unit 110-1 and the second segmented display unit 110-2 that are adjacent to each other can be equal to the sum of the interval between the first segmented display unit 110-1 and the second segmented display unit 110-2 and the width of the main border area MBA of each of the first segmented display unit 110-1 and the second segmented display unit 110-2.

[0105] Each of the segmented display units 110-1 and 110-2 includes bottom signal lines BGL and BDL for providing drive signals to multiple main pixel areas (MPA). That is, each of the segmented display units 110-1 and 110-2 includes providing scan signals to multiple main pixel areas (MPA). Figure 3 The bottom gate line BGL of the SCAN and the data signal provided to multiple main pixel areas MPA ( Figure 3 The bottom data line BDL of VDATA).

[0106] Each of the bottom signal lines BGL and BDL can extend along a straight line across the main display area MDA.

[0107] like Figure 8 As shown, bottom signal lines (e.g., bottom strobe lines BGL) extending along a first direction are arranged in a second direction with the same first interval G1 and spaced apart from each other. Bottom signal lines (e.g., bottom data lines BDL) extending along the second direction are arranged in the first direction with the same second interval G2 and spaced apart from each other.

[0108] Therefore, multiple main pixel areas (MPAs) arranged in a matrix in the main display area (MDA) can have the same size.

[0109] Figure 9 It shows Figure 1 A diagram showing an example of the front display unit. Figure 10 It shows the corresponding Figure 9 The diagram shows a portion of the front display unit of part D. Figure 11 , Figure 12 ,and Figure 13 It shows Figure 9 and Figure 6 A diagram of part B, showing an example. Figure 14 and 15 Figure 9 is shown. Figure 6 A diagram of part C in the example.

[0110] like Figure 9 As shown, the front display unit 120 is disposed in multiple segmented display units 110 ( Figure 6 On 110-1, 110-2, 110-3 and 110-4, and the size and shape are consistent with multiple segmented display units 110 ( Figure 6 The size and shape of the combination of 110-1, 110-2, 110-3 and 110-4 in the model correspond to each other.

[0111] The front display unit 120 includes multiple segmented display units 110 respectively. Figure 6 The multiple transmission areas TA1, TA2, TA3, and TA4 of 110-1, 110-2, 110-3, and 110-4, and the multiple segmented display units 110 ( Figure 6 The supplementary display area SDA between adjacent segmented display units in 110-1, 110-2, 110-3 and 110-4).

[0112] In one example, the display device 100 includes a first segmented display unit, a second segmented display unit, a third segmented display unit, and a fourth segmented display unit arranged in a 2×2 configuration. Figure 6 When 110-1, 110-2, 110-3, and 110-4 are included, the front display unit 120 may include multiple segmented display units 110 arranged in a 2×2 configuration and corresponding to each of the multiple segmented display units 110 (in the above cases). Figure 6The first transmission zone TA1, the second transmission zone TA2, the third transmission zone TA3, and the fourth transmission zone TA4 of 110-1, 110-2, 110-3, and 110-4.

[0113] The resolution achieved by the supplementary display area SDA is lower than that of multiple segmented display units 110 ( Figure 6 The resolution implemented in each main display area MDA (110-1, 110-2, 110-3 and 110-4) is as follows.

[0114] The front display unit 120 may also include a supplementary bezel area SBA, which is disposed outside and around the plurality of transmissive areas TA1, TA2, TA3 and TA4 and the supplementary display area SDA.

[0115] In one example, the width of the supplementary border area SBA can be equal to or greater than the width of the main border area MBA that overlaps with it.

[0116] like Figure 10 As shown, the front display unit 120 includes a plurality of alternative pixel areas RPA arranged in a matrix in the supplementary display area SDA.

[0117] In this respect, the resolution implemented in the supplementary display area SDA is lower than the resolution implemented in the main display area MDA. Therefore, the size of each alternative pixel area RPA arranged in the supplementary display area SDA is larger than that of each main pixel area arranged in the main display area MDA of each segmented display unit 110. Figure 7 The size of the MPA in the middle.

[0118] Furthermore, the front display unit 120 includes front signal lines FGL and FDL for providing drive signals to a plurality of alternative pixel areas RPA. That is, the front display unit 120 includes providing scan signals to the plurality of alternative pixel areas RPA. Figure 3 The front gate FGL of the SCAN; and the data signal provided to multiple alternative pixel areas RPA ( Figure 3 The front data line FDL of VDATA).

[0119] The front signal lines FGL and FDL are not only located in the supplementary display area SDA, but also in all the multiple transmission areas TA1, TA2, TA3 and TA4.

[0120] That is, the front signal lines FGL and FDL can extend across at least two transmission zones TA1, TA2, TA3 and TA4 arranged in the same direction as the extension direction and across the supplementary display zone SDA between the transmission zones TA1, TA2, TA3 and TA4.

[0121] Reference Figure 10 For example, a front signal line (e.g., a front gate line FGL) extending along the first direction may extend across a first transmission area TA1 and a second transmission area TA2 arranged in the first direction, and a supplementary display area SDA between them. Alternatively, a front signal line (e.g., a front gate line FGL) extending along the first direction may extend across a third transmission area TA3 and a fourth transmission area TA4 arranged in the first direction, and a supplementary display area SDA between them.

[0122] Reference Figure 10 For example, a front signal line (e.g., a front data line FDL) extending along the second direction may extend across a first transmission area TA1 and a third transmission area TA3 arranged in the second direction, and a supplementary display area SDA between them. Alternatively, a front signal line (e.g., a front data line FDL) extending along the second direction may extend across a second transmission area TA2 and a fourth transmission area TA4 arranged in the second direction, and a supplementary display area SDA between them.

[0123] However, according to one embodiment of this disclosure, in order to prevent moiré defects caused by the overlap of uniform patterns, the front signal lines FGL and FDL arranged in each of the plurality of transmission areas TA1, TA2, TA3 and TA4 may have an arrangement pattern different from the arrangement pattern of the bottom signal lines BGL and BDL of the main display area MDA of each of the plurality of segmented display units 110, or they may be arranged by changing the spacing and spaced apart from each other.

[0124] like Figure 11 As shown, the spacing between the front signal lines FGL and FDL arranged in each transmission zone TA1, TA2, TA3 and TA4 can vary based on a predetermined length.

[0125] In one example, such as Figure 11 As shown, the interval between the front signal lines FGL and FDL can vary randomly. However, this is just an example. Although not shown separately, the interval between at least two front signal lines, FGL and FDL, can vary randomly.

[0126] That is, the interval between the front gate lines FGL can vary randomly (G3 and G4). In addition, the interval between the front data lines FDL can vary randomly (G5 and G6).

[0127] Alternative locations, such as Figure 12 and 13 As shown, each front signal line FGL and FDL arranged in each transmission zone TA1, TA2, TA3 and TA4 can have a different shape than each bottom signal line BGL and BDL.

[0128] That is, although each of the bottom signal lines BGL and BDL can extend in a straight line, each of the front signal lines FGL and FDL arranged in each transmission zone TA1, TA2, TA3 and TA4 can extend in a predetermined direction while bending.

[0129] In one example, such as Figure 12 As shown, at least one of the front signal lines FGL and FDL is arranged in each transmission zone TA1, TA2, TA3 and TA4. Figure 12 The FDL in the middle has a shape with “C” shaped bends and straight lines arranged alternately to each other.

[0130] In another example, such as Figure 13 As shown, at least one of the front signal lines FGL and FDL is arranged in each transmission zone TA1, TA2, TA3 and TA4. Figure 13 The FGL can be extended in a zigzag pattern.

[0131] Furthermore, although not shown individually, in each transmission zone TA1, TA2, TA3 and TA4, the front signal lines FGL and FDL, including the curved portions and the front signal lines FGL and FDL extending along the straight lines, are arranged in a matrix such that the front signal lines FGL and FDL can have an irregular arrangement pattern.

[0132] In this way, the front signal lines FGL and FDL do not have a regularly repeating arrangement pattern. Therefore, the moiré effect caused by the overlap between the front signal lines FGL and FDL and the bottom signal lines BGL and BDL can be prevented.

[0133] like Figure 14 and Figure 15 As shown, in the front display unit 120, the multiple alternative pixel areas RPA for emitting light for image display are only provided in the supplementary display area SDA. That is, the alternative pixel areas RPA are not provided in the multiple transmission areas TA1, TA2, TA3 and TA4, but only the front signal lines FGL and FDL are provided in the multiple transmission areas TA1, TA2, TA3 and TA4.

[0134] That is, since the supplementary display area SDA is located between adjacent transmission areas in the multiple transmission areas TA1, TA2, TA3 and TA4, the front signal lines FGL and FDL used to provide drive signals to the multiple alternative pixel areas RPA are not only located in the supplementary display area SDA, but also in the multiple transmission areas TA1, TA2, TA3 and TA4.

[0135] The front signal lines FGL and FDL can extend across at least one of the multiple transmission zones TA1, TA2, TA3 and TA4, as well as the supplementary display zone SDA.

[0136] Therefore, as Figure 14 As shown, the front signal lines FGL and FDL in the supplementary display area SDA do not have the same regularly repeating arrangement pattern as the front signal lines FGL and FDL arranged in multiple transmission areas TA1, TA2, TA3 and TA4.

[0137] When the current signal lines FGL and FDL do not have a regularly repeating arrangement pattern in the multiple transmission zones TA1, TA2, TA3, and TA4 and the supplementary display area SDA, but instead have varying intervals between them to prevent moiré defects, the uniformity of the spacing between the surrogate pixel areas RPA decreases. As a result, the color mixing characteristics of the light beam emitted from adjacent surrogate pixel area RPAs in one area may differ from those in another area. Therefore, the improvement in image quality in the supplementary display area SDA is limited.

[0138] To overcome this limitation, such as Figure 15 As shown, the front signal lines FGL and FDL can be arranged and spaced apart from each other at the same interval G8 in the supplementary display area SDA. This is not to prevent the front signal lines FGL and FDL from being randomly arranged in multiple transmission areas TA1, TA2, TA3 and TA4 due to moiré defects.

[0139] For this purpose, the front signal lines FGL and FDL may include a curved pattern BP located at the edge of each transmission zone TA1, TA2, TA3 and TA4 adjacent to the supplementary display zone SDA.

[0140] The resolution implemented in the supplementary display area SDA is lower than that implemented in the main display area MDA. Therefore, the size of each alternative pixel area RPA arranged in the supplementary display area SDA is larger than the size of each primary pixel area MPA arranged in the main display area MDA of each segmented display unit 110.

[0141] In addition, such as Figure 14 and Figure 15 As shown, the edge of the supplementary display area SDA can overlap with a portion of the main display area MDA.

[0142] That is, each of the at least one alternative pixel area RPA located at the edge of the supplementary display area can overlap with at least one main pixel area MPA.

[0143] In this way, viewers can prevent the boundary between the supplementary display area SDA and the main display area MPA from being easily identified.

[0144] As described above, a display device 100 according to one embodiment of the present disclosure includes a front display unit 120 disposed on a plurality of segmented display units 110 arranged in a matrix.

[0145] The front display unit 120 includes a plurality of transmissive areas TA corresponding to a plurality of segmented display units 110 and a supplementary display area SDA corresponding to the boundary between two adjacent segmented display units 110.

[0146] Because of the front display unit 120, the user may not easily identify the boundaries between the multiple segmented display units 110. Instead, the multiple segmented display units 110 can function as a single, unified display unit.

[0147] Therefore, when multiple segmented display units 110 achieve high resolution, the display device 100 can overcome limitations related to line resistance and image quality, and can achieve both a large screen size and high resolution.
