[0044] Hereinafter, a display device according to some embodiments will be described in more detail with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals are used for the same components, and some redundant descriptions of the same components may be omitted.

[0045] Figure 1 is a plan view showing a display device according to some embodiments.

[0046] refer to Figure 1 According to some embodiments, the display device DD may include a display area DA and a non-display area NDA. The display area DA may be defined as an area capable of emitting light. In addition, a component for transmitting a signal to the display area DA may be located in the non-display area NDA.

[0047] A plurality of pixels may be located in the display area DA. For example, a pixel PX may be located in the display area DA. Each of the plurality of pixels may refer to an area where light emitted from a light emitting element is emitted to the outside of the display device DD. For example, a pixel PX may refer to an area where light emitted from a light emitting element (e.g., Figure 7 The light emitted by the light emitting element LED is emitted to an area outside the display device DD. The plurality of pixels may be repeatedly arranged in a first direction DR1 and in a second direction DR2 crossing the first direction DR1.

[0048] The non-display area NDA may be arranged around the display area DA (e.g., in the periphery of the occupied area of ​​the display area DA or outside the occupied area of ​​the display area DA). For example, the non-display area NDA may surround at least a portion of the display area DA. A driving unit may be located in the non-display area NDA. The driving unit may provide a signal or voltage to a plurality of pixels. For example, the driving unit may include a data driving unit and a gate driving unit, etc. The non-display area NDA may not display an image.

[0049] Figure 2 It is along Figure 1 The line I-I' intercepts Figure 1 A cross-sectional view of a display device. Figure 3 is included in Figure 2 An enlarged cross-sectional view of a flange in a display device. Figure 4 It is shown Figure 2 A plan view of the XY portion of the display device.

[0050] refer to Figure 2 , the display device DD according to some embodiments may include a display panel PNL, a cover BC, a printed circuit board PCB, a flexible printed circuit board FPCB, a driving chip IC, a fixing bracket SB, a flange FG, and a tape TP.

[0051] The display panel PNL may include a plurality of pixels. For example, the display panel PNL may include pixels (eg, Figure 1 Each of the plurality of pixels may emit light.

[0052] According to some embodiments, the cover BC may be located below the display panel PNL. The cover BC may protect the lower surface of the display panel PNL. For example, the cover BC may be located between the display panel PNL and the flange FG, and may prevent or reduce the impact applied from the flange FG from being transmitted to the display panel PNL. According to some embodiments, the cover BC may be omitted. In this case, the flange FG, the printed circuit board PCB, and the tape TP may be located below the display panel PNL.

[0053] The printed circuit board PCB may be located under the cover BC. For example, the printed circuit board PCB may include a driving board and a plurality of circuit components mounted on the driving board. The printed circuit board PCB may generate and transmit a signal for driving the display panel PNL. For example, the printed circuit board PCB may apply a driving signal and a driving voltage, etc., to the display panel PNL.

[0054] The driver chip IC may be located below the printed circuit board PCB. In a plan view, the driver chip IC may partially overlap the printed circuit board PCB. The driver chip IC may convert a digital data signal among the signals into an analog data signal.

[0055] The flexible printed circuit board FPCB may electrically connect the display panel PNL and the printed circuit board PCB. The flexible printed circuit board FPCB may extend from the top surface of the display panel PNL along the side surface. In addition, the flexible printed circuit board FPCB may be fixed on the bottom surface of the printed circuit board PCB. To this end, the flexible printed circuit board FPCB may be flexible.

[0056] The fixing bracket SB may be located below the cover BC. The fixing bracket SB may include a bottom part BP and a side part SD. The side part SD may be connected to the bottom part BP. For example, the side part SD may be connected to an edge of the bottom part BP. In addition, the side part SD may be perpendicular to the bottom part BP.

[0057] Since the fixing bracket SB includes the side part SD and the bottom part BP, the fixing bracket SB can accommodate the cover BC. In addition, the fixing bracket SB can also accommodate the printed circuit board PCB, the flexible printed circuit board FPCB, the driving chip IC, the tape TP and the flange FG.

[0058] The fixing bracket SB may further include a support part SP. The support part SP may contact each of the bottom part BP and the side part SD. For example, the support part SP may be a part extending from each of the bottom part BP and the side part SD. According to some embodiments, the support part SP may have a rectangular shape in a cross-sectional view.

[0059] The cover BC may be attached to the support member SP. For example, the cover BC may be attached to the support member SP by an adhesive tape TP.

[0060] According to some embodiments, the side member SD may define a groove H, which may be a portion from which a portion of the side member SD is removed. According to some embodiments, the groove H may have a polygonal shape in a cross-sectional view. The groove H may have a rectangular shape in a cross-sectional view. However, the present disclosure is not limited thereto, and the groove H may have a shape other than a polygonal shape in a cross-sectional view. For example, the groove H may have a semicircular shape or a semi-elliptical shape in a cross-sectional view.

[0061] Also refer to Figure 3 , flange FG may be located below cover BC.

[0062] The flange FG may include a first part P1, a second part P2, a third part P3, and a fourth part P4. For example, the flange FG may include metal.

[0063] The first part P1 of the flange FG may be accommodated by the groove H. According to some embodiments, the first part P1 may have a convex shape in a direction away from the second part P2 of the flange FG. That is, the first part P1 of the flange FG may have a convex shape in a direction opposite to the first direction DR1. For example, the first part P1 of the flange FG may have a semicircular shape or a semi-elliptical shape, etc.

[0064] Also refer to Figure 4 , the groove H may extend in the second direction DR2. In addition, the first part P1 of the flange FG may be spaced apart from the side part SD of the fixing bracket SB. That is, the first part P1 of the flange FG may not contact the side part SD of the fixing bracket SB.

[0065] As will be referenced later Figure 6 , Figure 7 and Figure 8Described in more detail, when manufacturing the display device DD, the flange FG may be rotated with the second direction DR2 as the axis. That is, the first part P1 of the flange FG may be rotated with the second direction DR2 as the axis. As described above, the first part P1 of the flange FG may have a convex shape. Therefore, when the first part P1 of the flange FG is rotated, the first part P1 of the flange FG may not contact the side part SD of the fixing bracket SB. Alternatively, when the first part P1 of the flange FG is rotated, the possibility of the first part P1 of the flange FG contacting the side part SD of the fixing bracket SB may be significantly reduced. Therefore, no impact may occur between the first part P1 of the flange FG and the side part SD of the fixing bracket SB. Therefore, it is possible to prevent or reduce the impact from being transmitted from the first part P1 of the flange FG to the display panel PNL and the cover BC through the flange FG.

[0066] The second part P2 of the flange FG may contact the first part P1 of the flange FG. For example, the second part P2 of the flange FG may contact the first part P1 of the flange in the first direction DR1. For example, the second part P2 of the flange FG may have a rectangular shape in a cross-sectional view. However, the present disclosure is not limited thereto, and the second part P2 of the flange may have a shape other than a rectangular shape in a cross-sectional view.

[0067] According to some embodiments, the second part P2 of the flange FG may not be received by the groove H. According to some embodiments, the second part P2 of the flange FG may be partially received by the groove H. In this case, a portion of the first part P1 of the flange FG and the second part P2 of the flange FG may be received by the groove H.

[0068] Reference again Figure 2 and Figure 3 , the third part P3 of the flange FG may be in contact with the cover BC. For example, the third part P3 of the flange FG may include a contact surface PA in contact with the cover BC. In addition, the third part P3 of the flange may include a first corner portion PC. The first corner portion PC may be a surface in contact with the contact surface PA. For example, the first corner portion PC may be a corner portion of the third part P3 of the flange FG. The corner portion may be adjacent to the cover BC.

[0069] According to some embodiments, the first corner portion PC may have a chamfered shape in a cross-sectional view. For example, the first corner portion PC may have a convex shape toward the cover BC. That is, the first corner portion PC may be a curved surface.

[0070] According to some embodiments, the first corner portion PC may be spaced apart from the cover BC. That is, the first corner portion PC may not be in contact with the cover BC. That is, since the first corner portion PC has a chamfered shape in a cross-sectional view, the first corner portion PC may not be in contact with the cover BC. Therefore, it is possible to prevent or reduce the impact transmitted from the flange FG from being applied to the display panel PNL and the cover BC through the first corner portion PC. For example, the impact transmitted from the flange FG may be generated when the flange FG is rotated during the manufacturing process of the display device DD.

[0071] The fourth part P4 of the flange FG may connect the second part P2 of the flange FG and the third part P3 of the flange FG. For example, the fourth part P4 of the flange FG may be connected to one end of the second part P2 of the flange FG. In addition, the fourth part P4 of the flange FG may be connected to one end of the third part P3 of the flange FG. For example, the fourth part P4 of the flange FG may be parallel to the side part SD of the fixing bracket SB.

[0103] Figure 6 , Figure 7 and Figure 8 It shows the manufacturing Figure 2 A cross-sectional view of a method for displaying a device.

[0104] refer to Figure 6 , the display panel PNL, the cover BC, the flange FG (refer to Figure 2 ), printed circuit board PCB, flexible printed circuit board FPCB, driving chip IC, tape TP and fixing bracket SB.

[0105] A cover BC may be formed under the display panel PNL. In addition, a printed circuit board PCB may be formed under the cover BC. In addition, a driving chip IC may be formed under the printed circuit board PCB. In addition, a flexible printed circuit board FPCB may be formed to electrically connect the display panel PNL and the printed circuit board PCB.

[0106] In addition, a flange FG may be formed under the cover BC. The flange FG may include a first part P1, a second part P2, a third part P3, and a fourth part P4. In addition, a fixing bracket SB may be formed under the cover BC. The fixing bracket SB may include a bottom part BP and a side part SD.

[0107] The display panel PNL, the cover BC, the printed circuit board PCB, the flexible printed circuit board FPCB, the driving chip IC, the flange FG, the tape TP and the fixing bracket SB may be aligned so that the first part P1 of the flange FG is received by the groove H.

[0108] The display panel PNL, the cover BC, the printed circuit board PCB, the flexible printed circuit board FPCB, the driving chip IC, the flange FG and the tape TP may constitute a first unit. Figure 2 The method of the display device DD) may include the step of coupling the first unit and the fixing bracket SB to each other. Figure 6 , Figure 7 and Figure 8 The step of coupling the first unit and the fixing bracket SB to each other may be shown.

[0109] refer to Figure 7 , the first unit can rotate with the second direction DR2 as the axis. When the first unit rotates, the flange FG (refer to Figure 2 ) can support and guide the first unit. That is, the flange FG can support and guide the first unit so that the first unit is well attached to the fixing bracket SB.

[0110] As above reference Figure 2 , Figure 3 and Figure 4 As described, the first part P1 of the flange FG may have a convex shape. Therefore, when the first part P1 of the flange FG rotates, the first part P1 of the flange FG may not contact the side part SD of the fixing bracket SB. Alternatively, when the first part P1 of the flange FG rotates, the possibility of the first part P1 of the flange FG contacting the side part SD of the fixing bracket SB can be significantly reduced. Therefore, no impact may occur between the first part P1 of the flange FG and the side part SD of the fixing bracket SB. Therefore, when manufacturing the display device, the transmission of the impact from the first part P1 of the flange FG through the flange FG to the display panel PNL and the cover BC can be prevented or reduced. Even if the first part P1 of the flange FG contacts the side part SD of the fixing bracket SB, due to the first corner portion (for example, Figure 3 The first corner portion PC) of the display panel may have a chamfered shape in a cross-sectional view, and thus an impact transmitted from the flange FG may be prevented or reduced from being applied to the display panel PNL and the cover member BC through the first corner portion.

[0111] Fig. 9 is a cross-sectional view showing a flange according to some embodiments. Fig. 9 The flange FG' described can be compared with the reference Figure 3 The flanges FG described are substantially the same or similar, and therefore, redundant descriptions will be omitted or simplified.

[0112] refer to Fig. 9According to some embodiments, the flange FG' may include a first part P1', a second part P2, a third part P3, and a fourth part P4. The first part P1' may be grooved (eg, Figure 3 The groove H) accommodates.

[0113] The first part P1' of the flange FG' may include a parallel surface P1A and a second angle portion P1D. The parallel surface P1A may be aligned with the side part (eg, Figure 3 That is, the parallel surface P1A may be spaced apart from the side member.

[0114] According to some embodiments, the second corner portion P1D may have a chamfered shape in a cross-sectional view. For example, the second corner portion P1D may have a convex shape in a direction away from the second part P2 of the flange FG'. That is, the second corner portion P1D may be a curved surface. Since the second corner portion P1D has a chamfered shape in a cross-sectional view, when the first part P1' of the flange FG' rotates, the second corner portion P1D may not contact the side part. Alternatively, when the first part P1' of the flange FG' rotates, the possibility of the second corner portion P1D contacting the side part can be significantly reduced. Therefore, it is possible to prevent or reduce the impact from being transmitted from the second corner portion P1D through the flange FG' to the display panel (for example, Figure 2 display panel PNL) and a cover (eg, Figure 2 Cover BC).
