[0029] FIG. 1 is a side view of a deposition apparatus according to an embodiment.

[0030] Referring to FIG. 1, a deposition apparatus (EA) according to an embodiment may include a chamber (CB), a deposition source (ES), and a deposition mask (MSK).

[0031] The chamber (CB) may have an internal space. The internal space of the chamber (CB) may be a workspace prepared for a deposition process. A deposition target may be housed (or placed) inside the chamber (CB). For example, a mother substrate (MSB), which is the deposition target, may be placed inside the chamber (CB).

[0032] A deposition source (ES) may be placed inside a chamber (CB). The deposition source (ES) contains a deposition material and can supply the contained deposition material into the internal space of the chamber (CB). The deposition material may include a material that forms a predetermined pattern layer (e.g., a light-emitting layer) on a mother substrate (MSB). The deposition source (ES) may vaporize or sublimate the deposition material by applying energy (e.g., thermal energy, light energy, or vibrational energy, etc.) to the deposition material. As an example, the deposition source (ES) may contain a heater inside, and the deposition material inside the deposition source (ES) may be melted or sublimated by heating the deposition material through the operation of the heater. The deposition source (ES) may be replaceable. The deposition source (ES) may be replaced with a new deposition source when the contained deposition material is depleted.

[0033] A deposition mask (MSK) may be placed between a mother substrate (MSB) and a deposition source (ES). The deposition mask (MSK) may be aligned to face the deposition target. The deposition mask (MSK) may block the deposition material in some areas and not block the deposition material in other areas. Accordingly, the deposition material may be selectively deposited only on specific areas of the deposition target. The deposition mask (MSK) may include opening areas. The deposition material may be provided to the deposition target (or mother substrate (MSB)) through the opening areas. In an embodiment, deposition may be performed simultaneously on the deposition targets using a single deposition mask (MSK).

FIG. 4 is an enlarged perspective view of a portion of a deposition mask according to an embodiment. FIG. 5 to 7 are cross-sectional views of a deposition mask according to an embodiment.

[0035] Referring to FIGS. 2 to 7, the deposition mask (MSK) may include a mask frame (MF) and a mask sheet (MS).

[0036] The mask frame (MF) may include an opening region (MFO). The opening region (MFO) may be located at the center of the mask frame (MF). FIG. 3 illustrates an embodiment in which the mask frame (MF) includes a single opening region (MFO), but is not necessarily limited thereto. Depending on the embodiment, the opening region (MFO) may be composed of multiple parts.

[0037] The mask frame (MF) may include an outer surface (MF1), an inner surface (MF2), an upper surface (MF3), and / or a lower surface (MF4). An opening region (MFO) of the mask frame (MF) may be surrounded by the inner surface (MF2). Mask sheets (MS) may be disposed on the upper surface (MF3) of the mask frame (MF). Each of the mask sheets (MS) may include an opening (MSO) that overlaps with the opening region (MFO) of the mask frame (MF). A deposition material may be deposited on a mother substrate (MSB) by passing through the opening region (MFO) of the mask frame (MF) and the opening (MSO) of the mask sheets (MS).

[0038] The mask frame (MF) may include a first hole (H1) penetrating the outer side (MF1). The first hole (H1) may penetrate the outer side (MF1) in a second direction (DR2). The first hole (H1) may include first to fourth sub-holes (H11 to H14). The first to fourth sub-holes (H11 to H14) of the first hole (H1) may be spaced apart in a first direction (DR1) that intersects the second direction (DR2). In the drawings, an embodiment in which the first hole (H1) includes four sub-holes (H11 to H14) is illustrated, but it is not necessarily limited thereto, and the number of sub-holes of the first hole (H1) can be varied. In the embodiment, the first hole (H1) may be formed by milling, but it is not necessarily limited thereto.

[0039] The mask frame (MF) may include a second hole (H2) penetrating the inner side (MF2). The second hole (H2) may penetrate the inner side (MF2) in a second direction (DR2). The second hole (H2) may include first to fourth sub-holes (H21 to H24). The first to fourth sub-holes (H21 to H24) of the second hole (H2) may be spaced apart in a first direction (DR1). Although the drawings illustrate an embodiment in which the second hole (H2) includes four sub-holes (H21 to H24), it is not necessarily limited thereto, and the number of sub-holes of the second hole (H2) can be varied. In the embodiment, the second hole (H2) may be formed by milling, but is not necessarily limited thereto.

[0040] The mask frame (MF) may include a recess (GR) recessed from the upper surface (MF3). The recess (GR) may include a long side extending in a first direction (DR1) and a short side extending in a second direction (DR2). Although the drawings illustrate an embodiment in which the recess (GR) has a planar rectangular shape, it is not necessarily limited thereto, and the planar shape of the recess (GR) can be varied. In the embodiment, the recess (GR) may be formed by milling, but is not necessarily limited thereto.

[0041] In an embodiment, one recess (GR) may overlap with the first to fourth sub-holes (H11 to H14) of the first hole (H1) and / or the first to fourth sub-holes (H21 to H24) of the second hole (H2), but is not necessarily limited thereto.

[0042] In the embodiment, fixing members (FM1, FM2) may be further disposed around the recess (GR). In the embodiment, a first fixing member (FM1) may be disposed on one side of the recess (GR), and a second fixing member (FM2) may be disposed on the other side of the recess (GR). The fixing members (FM1, FM2) may serve to fix or combine the mask frame (MF) and the mask sheet (MS) with each other. For example, the mask frame (MF) and the mask sheet (MS) may be fixed by welding, but are not necessarily limited thereto.

[0043] The mask frame (MF) may include a connecting portion (CN) connected to a first hole (H1), a second hole (H2), and / or a recess (GR). A first side of the connecting portion (CN) may be connected to the first hole (H1), a second side of the connecting portion (CN) may be connected to the second hole (H2), and an upper portion of the connecting portion (CN) may be connected to the recess (GR).

[0044] The connecting portion (CN) can penetrate at least partially into the interior of the mask frame (MF). For example, as shown in FIG. 5, the connecting portion (CN) can penetrate at least partially into the interior of the mask frame (MF) in a third direction (DR3) that intersects (or is orthogonal) with the first direction (DR1) and / or the second direction (DR2).

[0045] Alternatively, as shown in FIG. 6, the first hole (H1) and the second hole (H2) may penetrate at least partially into the interior of the mask frame (MF) in a fourth direction (DR4) inclined with the second direction (DR2) and / or the third direction (DR3), and the connecting part (CN) may penetrate at least partially into the interior of the mask frame (MF) in a fifth direction (DR5) intersecting (or orthogonal) with the fourth direction (DR4).

[0046] Alternatively, as illustrated in FIG. 7, the first hole (H1) and the second hole (H2) may penetrate at least partially into the interior of the mask frame (MF) in the fifth direction (DR5), and the connecting portion (CN) may penetrate at least partially into the interior of the mask frame (MF) in the sixth direction (DR6) which intersects (or is orthogonal) the fifth direction (DR5). In the embodiment, the connecting portion (CN) may be formed by milling, but is not necessarily limited thereto.

[0047] In an embodiment, the first hole (H1), the second hole (H2), and / or the connecting portion (CN) may have a Venturi tube shape. For example, the first hole (H1) may include a first region (H1A) and a second region (H1B) with different diameters. The first region (H1A) of the first hole (H1) may be a region where the diameter decreases as it moves from the outer side (MF1) toward the connecting portion (CN). The second region (H1B) of the first hole (H1) may be a region with a constant diameter. The diameter of the first region (H1A) of the first hole (H1) may be smaller than the diameter of the second region (H1B) of the first hole (H1). The first region (H1A) of the first hole (H1) may be located between the second region (H1B) of the first hole (H1) and the connecting portion (CN).

[0048] The second hole (H2) may include a first region (H2A) and a second region (H2B) having different diameters. The first region (H2A) of the second hole (H2) may be a region where the diameter decreases as it moves from the inner side (MF2) toward the connecting part (CN). The second region (H2B) of the second hole (H2) may be a region with a constant diameter. The diameter of the first region (H2A) of the second hole (H2) may be smaller than the diameter of the second region (H2B) of the second hole (H2). The first region (H2A) of the second hole (H2) may be located between the second region (H2B) of the second hole (H2) and the connecting part (CN).

[0049] The second region (H1B) of the first hole (H1) and / or the second region (H2B) of the second hole (H2) can serve as a passage for the inflow of cleaning gas or the discharge of residual cleaning liquid. The first region (H1A) of the first hole (H1) and / or the first region (H2A) of the second hole (H2) may have the characteristic of the pressure decreasing as the fluid velocity increases. In an embodiment, when cleaning gas is introduced through the second region (H1B) of the first hole (H1), the flow velocity increases and the pressure decreases as it passes through the first region (H1A) of the first hole (H1). As the pressure of the cleaning gas decreases, the cleaning liquid remaining between the mask frame (MF) and the mask sheet (MS), for example in the recess (GR), flows into the connection (CN) and is discharged through the second region (H2B) of the second hole (H2), allowing the residual cleaning liquid to be easily removed.

[0050] In the embodiment, when the cleaning gas is introduced through the second region (H2B) of the second hole (H2), the flow rate increases and the pressure decreases as it passes through the first region (H2A) of the second hole (H2). As the pressure of the cleaning gas decreases, the cleaning liquid remaining between the mask frame (MF) and the mask sheet (MS), for example in the recess (GR), flows into the connection part (CN) and is discharged through the second region (H1B) of the first hole (H1), allowing the residual cleaning liquid to be easily removed. Accordingly, the impact caused by the residual cleaning liquid can be minimized, thereby improving the reliability of the display device (or electronic device).

[0051] Hereinafter, a display device manufactured using a deposition mask (MSK) described with reference to FIGS. 1 to 7 and an electronic device including the same will be described.

[0052] FIG. 8 is a block diagram showing an example of a display device.

[0053] The display device (100) of Fig. 8 can be manufactured using the deposition mask (MSK) described above.

[0054] Referring to FIG. 8, the display device (100) may include a display panel (110), a gate driver (120), a data driver (130), a voltage generator (140), and a controller (150).

[0055] The display panel (110) may include subpixels (SP). The subpixels (SP) may be connected to a gate driver (120) through first to m gate lines (GL1 to GLm). The subpixels (SP) may be connected to a data driver (130) through first to n data lines (DL1 to DLn).

[0056] Each of the subpixels (SP) may include at least one light-emitting element configured to generate light. Accordingly, each of the subpixels (SP) may generate light of a specific color, such as red, green, blue, cyan, magenta, yellow, etc. Two or more of the subpixels (SP) may form a single pixel (PXL). For example, as illustrated in FIG. 8, three subpixels (SP) may form a single pixel (PXL).

[0057] The gate driver (120) can be connected to subpixels (SP) arranged in a row direction through the first to m gate lines (GL1 to GLm). The gate driver (120) can output gate signals to the first to m gate lines (GL1 to GLm) in response to a gate control signal (GCS). In an embodiment, the gate control signal (GCS) may include a start signal indicating the start of each frame, a horizontal synchronization signal for outputting gate signals in synchronization with the timing at which data signals are applied, etc.

[0058] In an embodiment, first to m light emission control lines (EL1 to ELm) connected to row-direction subpixels (SP) may be further provided. In this case, the gate driver (120) may include a light emission control driver configured to control the first to m light emission control lines (EL1 to ELm), and the light emission control driver may operate under the control of the controller (150).

[0059] The gate driver (120) may be positioned on one side of the display panel (110). However, embodiments are not limited thereto. For example, the gate driver (120) may be divided into two or more physically and / or logically separated drivers, and such drivers may be positioned on one side of the display panel (110) and on the other side of the display panel (110) opposite to that side. Thus, the gate driver (120) may be positioned around the display panel (110) in various forms according to the embodiments.

[0060] The data driver (130) can be connected to subpixels (SP) arranged in a column direction through the first to nth data lines (DL1 to DLn). The data driver (130) can receive image data (DATA) and a data control signal (DCS) from the controller (150). The data driver (130) can operate in response to the data control signal (DCS). In an embodiment, the data control signal (DCS) may include a source start pulse, a source shift clock, a source output enable signal, etc.

[0061] The data driver (130) can apply data signals having grayscale voltages corresponding to image data (DATA) to the first to nth data lines (DL1 to DLn) using voltages from the voltage generator (140). When a gate signal is applied to each of the first to mth gate lines (GL1 to GLm), data signals corresponding to image data (DATA) can be applied to the data lines (DL1 to DLm). Accordingly, the corresponding subpixels (SP) can generate light corresponding to the data signals. Accordingly, an image can be displayed on the display panel (110).

[0062] In the embodiment, the gate driver (120) and the data driver (130) may include CMOS (complementary metal-oxide semiconductor) circuit elements.

[0063] The voltage generator (140) can operate in response to a voltage control signal (VCS) from the controller (150). The voltage generator (140) can be configured to generate voltages and provide the generated voltages to the components of the display device (100). For example, the voltage generator (140) can be configured to generate voltages by receiving an input voltage from outside the display device (100), adjusting the received voltage, and regulating the adjusted voltage.

[0064] The voltage generator (140) can generate a first power supply voltage (VDD) and a second power supply voltage (VSS), and the generated first and second power supply voltages (VDD, VSS) can be provided to subpixels (SP). The first power supply voltage (VDD) has a relatively high voltage level, and the second power supply voltage (VSS) may have a lower voltage level than the first power supply voltage (VDD). In another embodiment, the first power supply voltage (VDD) or the second power supply voltage (VSS) may be provided by an external device of the display device (100).

[0065] In addition to this, the voltage generator (140) can generate various voltages. For example, the voltage generator (140) can generate an initialization voltage applied to subpixels (SP). For example, during a sensing operation to sense the electrical characteristics of the transistors and / or light-emitting elements of the subpixels (SP), a predetermined reference voltage may be applied to the first to nth data lines (DL1 to DLn), and the voltage generator (140) can generate such a reference voltage.

[0066] The controller (150) can control the various operations of the display device (100). The controller (150) can receive input image data (IMG) and a control signal (CTRL) for controlling the display thereof from an external source. In response to the control signal (CTRL), the controller (150) can provide a gate control signal (GCS), a data control signal (DCS), and a voltage control signal (VCS).

[0067] The controller (150) can convert the input image data (IMG) to be suitable for the display device (100) or display panel (110) and output image data (DATA). In an embodiment, the controller (150) can output image data (DATA) by aligning the input image data (IMG) to be suitable for row-unit subpixels (SP).

[0068] Two or more components of the data driver (130), voltage generator (140), and controller (150) may be mounted on a single integrated circuit. As illustrated in FIG. 8, the data driver (130), voltage generator (140), and controller (150) may be included in a driver integrated circuit (DIC). In this case, the data driver (130), voltage generator (140), and controller (150) may be functionally separate components within a single driver integrated circuit (DIC). In another embodiment, at least one of the data driver (130), voltage generator (140), and controller (150) may be provided as a component separate from the driver integrated circuit (DIC).

[0069] FIG. 9 is a block diagram showing an embodiment of any one of the subpixels of FIG. 8. In FIG. 9, subpixels (SPij) arranged in the i-th row (i is an integer greater than or equal to 1 and less than or equal to m) and the j-th column (j is an integer greater than or equal to 1 and less than or equal to n) of the subpixels (SP) of FIG. 8 may be illustrated as an example.

[0070] Referring to FIG. 9, the subpixel (SPij) may include a subpixel circuit (SPC) and a light-emitting element (LD).

[0071] A light-emitting element (LD) can be connected between a first power supply voltage node (VDDN) and a second power supply voltage node (VSSN). The first power supply voltage node (VDDN) is a node that transmits the first power supply voltage (VDD) of FIG. 8, and the second power supply voltage node (VSSN) may be a node that transmits the second power supply voltage (VSS) of FIG. 8.

[0072] The anode electrode (AE) of the light-emitting element (LD) may be connected to a first power supply voltage node (VDDN) through a sub-pixel circuit (SPC), and the cathode electrode (CE) of the light-emitting element (LD) may be connected to a second power supply voltage node (VSSN). For example, the anode electrode (AE) of the light-emitting element (LD) may be connected to the first power supply voltage node (VDDN) through one or more transistors included in the sub-pixel circuit (SPC).

[0073] The subpixel circuit (SPC) can be connected to the i-th gate line (GLi) among the first to m-th gate lines (GL1~GLm) of FIG. 8, the i-th light emission control line (ELi) among the first to m-th light emission control lines (EL1~ELm) of FIG. 8, and the j-th data line (DLj) among the first to n-th data lines (DL1~DLn) of FIG. 8. The subpixel circuit (SPC) can be configured to control the light-emitting element (LD) according to signals received through these signal lines.

[0074] The subpixel circuit (SPC) can operate in response to a gate signal received through the i-th gate line (GLi). The i-th gate line (GLi) may include one or more sub-gate lines. In an embodiment, the i-th gate line (GLi) may include first and second sub-gate lines (SGL1, SGL2). The subpixel circuit (SPC) can operate in response to gate signals received through the first and second sub-gate lines (SGL1, SGL2). Thus, when the i-th gate line (GLi) includes two or more sub-gate lines, the subpixel circuit (SPC) can operate in response to gate signals received through the corresponding sub-gate lines.

[0075] The subpixel circuit (SPC) can operate in response to a light emission control signal received through the i-th light emission control line (ELi). In an embodiment, the i-th light emission control line (ELi) may include one or more sub-light emission control lines. If the i-th light emission control line (ELi) includes two or more sub-light emission control lines, the subpixel circuit (SPC) can operate in response to light emission control signals received through the said sub-light emission control lines.

[0076] The subpixel circuit (SPC) can receive a data signal through the j-th data line (DLj). The subpixel circuit (SPC) can store a voltage corresponding to the data signal in response to at least one of the gate signals received through the first and second sub-gate lines (SGL1, SGL2). The subpixel circuit (SPC) can regulate the current flowing from the first power supply voltage node (VDDN) to the second power supply voltage node (VSSN) through the light-emitting element (LD) according to the stored voltage in response to a light-emitting control signal received through the i-th light-emitting control line (ELi). Accordingly, the light-emitting element (LD) can generate light of a brightness corresponding to the data signal.

[0077] FIG. 10 is a plan view showing an example of the display panel of FIG. 8.

[0078] Referring to FIG. 10, an embodiment (DP) of the display panel (110) of FIG. 8 may include a display area (DA) and a non-display area (NDA). The display panel (DP) may display an image through the display area (DA). The non-display area (NDA) may be placed around the display area (DA).

[0079] The display panel (DP) may include a substrate (SUB), subpixels (SP), and pads (PD).

[0080] Subpixels (SP) may be placed in a display area (DA) on a substrate (SUB). Subpixels (SP) may be arranged in a matrix form along a first direction (DR1) and a second direction (DR2) intersecting the first direction (DR1). However, embodiments are not limited thereto. For example, subpixels (SP) may be arranged in a zigzag form along the first direction (DR1) and the second direction (DR2). For example, subpixels (SP) may be arranged in a pentile form. The first direction (DR1) may be a row direction, and the second direction (DR2) may be a column direction. Two or more of the subpixels (SP) may form a single pixel (PXL).

[0081] Components for controlling subpixels (SP) may be disposed in a non-display area (NDA) on a substrate (SUB). For example, wiring connected to subpixels (SP), such as the first to m gate lines (GL1 to GLm) and the first to n data lines (DL1 to DLn) of FIG. 8, may be disposed in the non-display area (NDA).

[0082] At least one of the gate driver (120), data driver (130), voltage generator (140), and controller (150) of FIG. 8 may be integrated in the non-display area (NDA) of the display panel (DP).
