Description
Technical Field
[0001] The present application relates to the field of electronic technology, and in particular to a display panel and an electronic device. Background Art
[0002] Organic Light Emitting Diode (OLED) is an active light-emitting display device with the advantages of self-luminescence, wide viewing angle, high contrast, low power consumption, and extremely high response speed. With the continuous development of display technology, OLED technology is increasingly used in flexible display panels.
[0003] Among them, flexible display panels can be applied to foldable devices. However, after the foldable device is folded multiple times, creases are easily generated on the flexible display panel, causing the flexible display panel to be uneven at the crease position, thereby causing the flexible display panel to have a color deviation problem at the crease position. Summary of the invention
[0004] The embodiments of the present application provide a display panel and an electronic device, which can prevent the problem of color deviation of the display panel at the fold position.
[0005] In a first aspect, an embodiment of the present application provides a display panel, including:
[0006] a first display unit;
[0007] a second display unit;
[0008] a bendable portion connected between the first display portion and the second display portion, wherein the bendable portion can be bent so that the first display portion and the second display portion are overlapped with each other; the bendable portion comprises a pixel definition layer and a light-emitting pixel layer, wherein the pixel definition layer is formed with a pixel opening, and the light-emitting pixel layer is arranged in the pixel opening;
[0009] A first metal wiring is arranged on a side of the pixel definition layer away from the light-emitting pixel layer; and
[0010] A second metal wiring is arranged on a side of the pixel definition layer away from the light-emitting pixel layer; the orthographic projections of the second metal wiring and the first metal wiring on the plane where the light-emitting pixel layer is located are located on two opposite sides of the light-emitting pixel layer;
[0011] The minimum distance between the first metal wiring and the pixel opening is different from the minimum distance between the second metal wiring and the pixel opening.
[0012] In a second aspect, an embodiment of the present application further provides an electronic device, comprising a housing assembly and the display panel as described above, wherein the display panel is disposed on the housing assembly.
[0013] In the embodiment of the present application, by setting the minimum distance between the first metal wiring and the pixel opening and the minimum distance between the second metal wiring and the pixel opening to different sizes, the side where the metal wiring is farther away from the pixel opening can emit more light. Since the light emitted by the light-emitting pixel layer on this side is oblique light, that is, the light-emitting pixel layer can emit more oblique light on this side, the light output at this viewing angle is increased, that is, the light output at a large viewing angle is increased, thereby reducing the brightness attenuation at a large viewing angle, and further improving the problem of large visual angle color deviation at the crease position.

[0026] The embodiments of the present application provide a display panel and an electronic device, which can prevent the problem of color deviation of the display panel at the fold position. The technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0027] As used in the embodiments of the present application, "electronic devices" include, but are not limited to, devices configured to receive / send communication signals via a wireline connection (e.g., via a public switched telephone network (PSTN), a digital subscriber line (DSL), a digital cable, a direct cable connection, and / or another data connection / network) and / or via a wireless interface (e.g., for a cellular network, a wireless local area network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and / or another communication terminal). A communication terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", "electronic device", and / or "electronic device". Examples of electronic devices include, but are not limited to, satellite or cellular phones; personal communication system (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communication capabilities; PDAs that may include radiotelephones, pagers, Internet / intranet access, web browsers, notepads, calendars, and / or global positioning system (GPS) receivers; and conventional laptop and / or palmtop receivers, game consoles, or other electronic devices that include radiotelephone transceivers.
[0028] Understandable, see Figure 1 , Figure 1 This is a schematic diagram of a first state of an electronic device provided in an embodiment of the present application. The electronic device 100 may be an electronic device having a display panel 10. The electronic device 100 may be, but is not limited to, a mobile phone, a tablet computer, a game console, a smart watch, and other electronic devices. The electronic device 100 of this embodiment is described by taking a mobile phone as an example. The display panel 10 is located on the surface of the electronic device 100 to provide a human-computer interaction interface for the user.
[0029] The electronic device 100 includes a housing assembly 20, a display panel 10, and an electronic assembly (not shown in the figure), wherein the electronic assembly is disposed in the housing assembly 20, and the display panel 10 is covered on the housing assembly 20. The housing assembly 20 is used to carry the display panel 10 and protect the electronic assembly. It should be noted that in the present application specification, when a component is considered to be "disposed on" another component, it may be connected to or directly disposed on another component, or there may be a central component at the same time; when a component is considered to be "connected to" another component, it may be directly connected to another component or there may be a central component at the same time, that is, the two components may be indirectly connected.
[0030] The electronic components include a mainboard and a central processing unit, a memory, an antenna, a camera, a receiver, etc. arranged on the mainboard. It may also include a printed circuit board and a functional module (such as a battery, a connector, a fingerprint module, etc.) arranged on the printed circuit board.
[0031] The display panel 10 has a display side for emitting light to the outside. When the display panel 10 is working, the light is emitted to the display side, so that the user located at the display side can observe the content displayed by the display panel 10. In the present embodiment, the display panel 10 is an active-matrix organic light-emitting diode (AMOLED) display panel. As a self-luminous display, the AMOLED display screen does not need to be provided with a backlight module (BLM). Therefore, when the substrate substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the above-mentioned AMOLED display screen can have a bendable characteristic. In other embodiments, the display panel 10 can also be an organic light-emitting semiconductor (OLED) display screen panel.
[0032] The housing assembly 20 is used to form the outer contour of the electronic device 100, so as to accommodate the electronic devices, functional components, etc. of the electronic device 100, and at the same time form a sealing and protective effect on the electronic devices and functional components inside the electronic device 100. For example, the electronic devices and functional components such as the battery, mainboard, and sensor of the electronic device 100 can be arranged inside the housing assembly 20. The housing assembly 20 can be formed of plastic, glass, ceramic, fiber composite material, metal (for example, stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials.
[0033] Understandable, see Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of a second state of an electronic device provided in an embodiment of the present application. When the electronic device 100 is a foldable electronic device, the housing assembly 20 includes a first portion 21 and a second portion 22, and the first portion 21 and the second portion 22 are connected by a rotating shaft 23. Figure 2 As shown, the first part 21 and the second part 22 can be close to each other, so that the first part 21 and the second part 22 can be overlapped with each other to present a folded state. Figure 1 As shown, the first portion 21 and the second portion 22 can move away from each other to be arranged side by side to present an unfolded state.
[0034] It can also be understood that both the first part 21 and the second part 22 can include a middle frame and a back cover. Among them, the middle frame can be a thin plate or sheet-like structure, or it can be a hollow frame structure. The middle frame is used to provide support for the electronic devices or functional components in the electronic device 100, so as to install the electronic devices and functional components of the electronic device 100 together. For example, structures such as grooves and protrusions can be provided on the middle frame to facilitate the installation of electronic devices or functional components of the electronic device 100. It can be understood that the material of the middle frame can include metal or plastic.
[0035] The back cover is used to seal the electronic devices and functional components of the electronic device 100 together with the middle frame and the display panel 10 inside the electronic device 100 to protect the electronic devices and functional components of the electronic device 100. It can be understood that the material of the back cover can also include metal or plastic.
[0036] The above is an introduction to the overall structure of the electronic device 100. In order to more clearly illustrate the specific structure of the display panel 10, the specific structure of the display panel 10 and its related components will be specifically described below in conjunction with the accompanying drawings.
[0037] See also Figure 2 Combined with Figure 1 It can be understood that in order to meet the foldable requirements, the display panel 10 can be a flexible display panel. The display panel 10 can include a first display portion 11, a second display portion 12 and a bendable portion 13, the bendable portion 13 is connected between the first display portion 11 and the second display portion 12, and the bendable portion 13 can be bent so that the first display portion 11 and the second display portion 12 are overlapped and present a folded state.
[0038] It can be understood that the display panel 10 is carried on the shell assembly 20. When the electronic device 100 is in the unfolded state, the first part 21, the hinge 23 and the second part 22 of the shell assembly 20 are arranged along the first direction H1. For example, the first display part 11 can be carried by the first part 21, the bendable part 13 can be carried by the hinge 23, and the second display part 12 can be carried by the second part 22.
[0039] It can also be understood that when the electronic device 100 is in an unfolded state, the first display portion 11, the bendable portion 13 and the second display portion 12 are arranged along the first direction H1. When the electronic device 100 is in a folded state, the bendable portion 13 can be bent, and the first display portion 11 and the second display portion 12 can be stacked on each other.
[0040] It should be noted that after being folded multiple times, an electronic device is prone to creases on the flexible display panel, that is, it is easy to produce creases on the bendable part of the display panel, causing the display panel to be uneven at the crease position, thereby causing the flexible display panel to have a color deviation problem at the crease position.
[0041] It can be understood that the display panel includes a plurality of light-emitting pixel layers arranged at intervals, and the plurality of light-emitting pixel layers can be arranged in an array, and the plurality of light-emitting pixel layers can include but are not limited to red light-emitting units, green light-emitting units, and blue light-emitting units, and the three primary colors of light are mixed to form the displayed color, so that the display panel can provide a color picture. The brightness attenuation rate of light-emitting devices of different colors is inconsistent at different viewing angles. Therefore, the display panel will have color deviation when displaying pictures at different viewing angles.
[0042] In the related art, the display panel also includes metal wiring, which is made of Ti / Al / Ti, with a wiring width of about 3 to 5 μm, usually 3 μm, and a thickness of about 0.8 μm. Figure 3 As shown, it is a diagram showing the position relationship between the metal wiring and the light-emitting pixel layer in the prior art. It can be understood that Figure 3The thick solid arrow in the figure indicates the emission direction of the light. The pixel definition layer 14a is formed with a pixel opening 141a, the light-emitting pixel layer 13a is arranged at the pixel opening 141a, the first metal line 15a is arranged at the side of the pixel definition layer 14a away from the light-emitting pixel layer 13a, the second metal line 16a is arranged at the side of the pixel definition layer 14a away from the light-emitting pixel layer 13a, and the orthographic projections of the second metal line 16a and the first metal line 15a on the plane where the light-emitting pixel layer 13a is located are located on opposite sides of the light-emitting pixel layer 13a, and are symmetrically arranged with respect to the light-emitting pixel layer 13a. It can be understood that due to the presence of the first metal wire 15a and the second metal wire 16a, the large-angle light emitted by the light-emitting pixel layer (the angle between the light and the normal of the light-emitting pixel layer is greater than 40 degrees) is blocked by the first metal wire 15a and the second metal wire 16a, resulting in most of the inclined light on both sides of the normal of the light-emitting pixel layer 13a being blocked, thereby increasing the brightness attenuation of the light-emitting pixel layer 13a at a large viewing angle. It can be seen from the white light matching formula that at a large viewing angle, if the brightness attenuation degree of the red light pixel layer, the green light pixel layer and the blue light pixel layer is inconsistent with the change trend of the monochrome CIE color coordinates, a large viewing angle color deviation such as red or green is likely to occur. Therefore, when viewing the display panel from this viewing angle, color deviation will occur.
[0043] After being folded multiple times, a foldable electronic device is prone to creases on the flexible display panel, that is, it is easy to generate creases in the bendable part of the display panel, causing the display panel to be uneven at the crease position. In this way, even if the user views the display panel from the front, the unevenness of the display panel at the crease position causes the user to view the large-angle light emitted by the light-emitting pixel layer (the angle between the light and the normal of the light-emitting pixel layer is greater than 40 degrees), resulting in a problem of visual color deviation of the flexible display panel at the crease position.
[0044] Based on this, through repeated research by the inventors, the embodiment of the present application performs a differentiated design of metal routing on the bendable portion 13 of the display panel 10 to improve the brightness difference and viewing angle color deviation difference at the fold position.
[0045] See also Figure 4 , Figure 4 The first position relationship diagram of the metal wiring and the light-emitting pixel layer provided in the embodiment of the present application can be understood as follows: Figure 4 The thick solid arrow in the figure indicates the emission direction of the light. The bendable portion 13 of the display panel 10 includes a pixel definition layer 131 and a light-emitting pixel layer 132, and the pixel definition layer 131 is formed with a pixel opening 133. Exemplarily, the pixel opening 133 can be formed on the pixel definition layer 131 by masking, exposure, development, and etching processes.
[0046] The light-emitting pixel layer 132 is disposed in the pixel opening 133. It can be understood that the light-emitting pixel layer 132 is used to emit colored light.
[0047] The display panel 10 further includes a first metal wiring 14 and a second metal wiring 15 , wherein the first metal wiring 14 and the second metal wiring 15 may be touch wirings, and the touch wirings are electrically connected to the touch electrodes to implement the touch function of the display panel 10 .
[0048] The first metal wiring 14 is arranged on the side of the pixel definition layer 131 away from the light-emitting pixel layer 132, and the second metal wiring 15 is arranged on the side of the pixel definition layer 131 away from the light-emitting pixel layer 132. It can be understood that the orthographic projections of the second metal wiring 15 and the first metal wiring 14 on the plane where the light-emitting pixel layer 132 is located are located on opposite sides of the light-emitting pixel layer 132. Among them, the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 is different from the minimum distance L2 between the second metal wiring 15 and the pixel opening 133. That is, one of the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 and the minimum distance L2 between the second metal wiring 15 and the pixel opening 133 is larger, or one of the first metal wiring 14 and the second metal wiring 15 will deviate more from the pixel opening 133. It can be understood that the side where the metal wiring farther away from the pixel opening 133 is located can emit more oblique light. However, since the display panel 10 is uneven at the fold position, the user views the large-angle light emitted by the light-emitting pixel layer 132 (the angle between the light and the normal of the light-emitting pixel layer 132 is greater than 40 degrees). The above structure can adaptively adjust the oblique light energy emitted by the light-emitting pixel layer 132, thereby improving the color deviation problem at the fold position.
[0049] From the above, it can be seen that by setting the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 and the minimum distance L2 between the second metal wiring 15 and the pixel opening 133 to different sizes, the side of the metal wiring farther away from the pixel opening 133 can emit more light. Since the light emitted by the light-emitting pixel layer 132 on this side is oblique light, that is, the light-emitting pixel layer 132 can emit more oblique light on this side, the light output at this viewing angle is increased, that is, the light output at a large viewing angle is increased, thereby reducing the brightness attenuation at a large viewing angle, and further improving the problem of large viewing angle color deviation at the crease position.
[0050] That is, the embodiment of the present application increases the light output at a large viewing angle at a specific position by rationally utilizing the structure of the metal routing, thereby reducing the brightness attenuation at a large viewing angle and improving the problem of large viewing angle color deviation at the crease position.
[0051] It can be understood that in the embodiment of the present application, the light-emitting pixel layer 132 is an organic light-emitting device, for example, see Figure 5 , Figure 5 The schematic diagram of the structure of the metal wiring and the light-emitting pixel layer provided in the embodiment of the present application can be understood as follows: Figure 5 The thick solid arrow in represents the emission direction of the light. The light-emitting pixel layer 132 may include an anode layer 1321, an organic light-emitting layer 1322 and a cathode layer 1323 stacked in sequence from the bottom layer to the top layer. The anode layer 1321 is connected to the drain electrode of the thin film transistor, thereby realizing the light emission control of the organic light-emitting layer 1322. It can also be understood that the organic light-emitting layer 1322 may include a first common layer, a light-emitting layer and a second common layer. Among them, the first common layer is used for the injection and transmission of holes, and the first common layer includes a hole injection layer and a hole transport layer. Therefore, the first common layer can be called a hole transport functional layer. The second common layer is formed on the first common layer. The first common layer is used for the injection and transmission of electrons. The second common layer includes an electron injection layer and an electron transport layer. Therefore, the second common layer can be called an electron transport functional layer. The light-emitting layer is located between the first common layer and the second common layer. The light-emitting layer is an organic semiconductor with a special energy band structure. After absorbing electrons migrated from the anode, it can emit photons of a certain wavelength, and these photons enter our eyes as the colors we see. The cathode layer 1323 is formed on the organic light emitting layer 1322 and is used to provide electrons. In this embodiment, the cathode layer 1323 is made of a transparent material, so that the light generated by the organic light emitting layer 1322 is projected outward through the cathode layer 1323 .
[0052] It is also understandable that see Figure 6 , Figure 6 A schematic diagram of the structure of the metal wiring, encapsulation layer and light-emitting pixel layer provided in the embodiment of the present application. The display panel 10 may also include an encapsulation layer 16, which is formed on the cathode layer 1323 and covers the pixel definition layer 131. The encapsulation layer 16 mainly plays the role of blocking water and oxygen to prevent external water vapor from corroding and damaging the organic light-emitting layer 1322. The encapsulation layer 16 includes at least one organic layer and at least one inorganic layer alternately superimposed, the organic layer is located approximately in the middle of the encapsulation layer 16, and the inorganic layer is located on both sides of the encapsulation layer 16, and the organic layer is wrapped in the middle. The present application specification does not limit this. Accordingly, the first metal wiring 14 and the second metal wiring 15 can be formed on the encapsulation layer 16, and the first metal wiring 14 and the second metal wiring 15 are located on the side of the encapsulation layer 16 away from the pixel definition layer 131.
[0053] It should be noted that if Figure 7 As shown, Figure 7A schematic diagram of the structure of a display panel provided in an embodiment of the present application when a crease occurs. Since the first display portion 11, the bendable portion 13, and the second display portion 12 of the display panel 10 are arranged along the first direction H1, when the bendable portion 13 of the display panel 10 is bent multiple times to form a crease, the bendable portion 13 has a certain curvature in the first direction H1, resulting in the user viewing a large-angle light emitted by the light-emitting pixel layer 132 (the angle between the light and the normal of the light-emitting pixel layer 132 is greater than 40 degrees), and the user will experience color deviation at the crease when viewing the display panel 10.
[0054] Based on this, in order to adapt to the crease, such as Figure 4 As shown, the positions of the second metal wiring 15 and the first metal wiring 14 can be set as follows: in the first direction H1, the orthographic projections of the second metal wiring 15 and the first metal wiring 14 on the plane where the light-emitting pixel layer 132 is located are located on opposite sides of the light-emitting pixel layer 132, so that the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 is the distance in the first direction H1, and the minimum distance L2 between the second metal wiring 15 and the pixel opening 133 is also the distance in the first direction H1. In this way, the positions of the first metal wiring 14 and the second metal wiring 15 are adaptively adjusted according to the bending state of the fold, which can better meet the problem of improving color deviation.
[0055] It can be understood that the pixel opening 133 includes a first side wall 1331 and a second side wall 1332 arranged opposite to each other along the first direction H1. In order to enable the light-emitting pixel layer 132 to emit oblique light with a larger inclination angle, the first side wall 1331 and the second side wall 1332 can be inclined.
[0056] Exemplarily, the first side wall 1331 is inclined from one end of the first side wall 1331 close to the light-emitting pixel layer 132 toward one end close to the first metal wiring 14 and toward the side away from the light-emitting pixel layer 132, and the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 is the minimum distance between the first metal wiring 14 and one end of the first side wall 1331 close to the light-emitting pixel layer 132.
[0057] The second side wall 1332 is inclined from one end of the second side wall 1332 close to the light-emitting pixel layer 132 toward one end close to the second metal wiring 15 and toward the side away from the light-emitting pixel layer 132. The minimum distance L2 between the second metal wiring 15 and the pixel opening 133 is the minimum distance between the second metal wiring 15 and one end of the second side wall 1332 close to the light-emitting pixel layer 132.
[0058] It can be understood that the bendable portion 13 is connected between the first display portion 11 and the second display portion 12. Figure 7As shown, when a fold appears on the bendable portion 13 , the viewing angle of the bendable portion 13 starts to change from the connecting edge of the bendable portion 13 and the first display portion 11 or from the connecting edge of the bendable portion 13 and the second display portion 12 .
[0059] Based on this, in order to better improve the color deviation of the bendable portion 13, in some embodiments, please combine Figure 4 and Figure 7 , the first metal trace 14 is closer to the first display portion 11 or the second display portion 12 than the second metal trace 15, so that the second metal trace 15 is farther from the first display portion 11 or the second display portion 12, or in other words, the second metal trace 15 is farther from the connecting edge of the bendable portion 13 and the first display portion 11, or the second metal trace 15 is farther from the connecting edge of the bendable portion 13 and the second display portion 12. At this time, Figure 4 As shown, the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 is set to be smaller than the minimum distance L2 between the second metal wiring 15 and the pixel opening 133. That is, the position farther away from the connection edge of the bendable portion 13 and the first display portion 11 or the position farther away from the connection edge of the bendable portion 13 and the second display portion 12 can emit more light, or the position on the side where the second metal wiring 15 is located can emit more light, and because the light emitted by the light-emitting pixel layer 132 on this side is oblique light, that is, the light-emitting pixel layer 132 can emit more oblique light on this side, the light output at this viewing angle is increased, that is, the light output at a large viewing angle is increased, thereby reducing the brightness attenuation at a large viewing angle, and further improving the problem of color deviation at a large viewing angle at the fold position.
[0060] It is understandable that the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 and the minimum distance L2 between the second metal wiring 15 and the pixel opening 133 can be different by shifting the positions of the first metal wiring 14 and the second metal wiring 15 .
[0061] Of course, in some embodiments, the minimum distance L1 between the first metal wiring 14 and the second metal wiring 15 can be changed to achieve a difference between the minimum distance L2 between the first metal wiring and the pixel opening 133 and the minimum distance L2 between the second metal wiring 15 and the pixel opening 133. For example, Figure 8 As shown, Figure 8 A second position relationship diagram of the metal wiring and the light-emitting pixel layer provided in an embodiment of the present application. The width D1 of the first metal wiring 14 can be made wider, and the width D2 of the second metal wiring 15 can be made narrower than the width D1 of the first metal wiring 14, so that the minimum distance L1 between the first metal wiring 14 and the pixel opening 133 is smaller than the minimum distance L2 between the second metal wiring 15 and the pixel opening 133.
[0062] It is understandable that the display panel 10 usually uses three primary colors to mix the displayed colors, thereby enabling the display panel 10 to provide a color image. Figures 9 to 11 , Fig. 9 A position relationship diagram of the first red pixel and the metal wiring provided in an embodiment of the present application, Fig.10 A position relationship diagram of the first green pixel and the metal wiring provided in an embodiment of the present application, Fig.11 The position relationship diagram of the first blue pixel and the metal wiring provided in the embodiment of the present application. The light-emitting pixel layer 132 may include a first red pixel 1324 , a first green pixel 1325 and a first blue pixel 1326 .
[0063] Among them, see Fig. 9 , the pixel definition layer 131 is formed with a first pixel opening 1333, and the first red pixel 1324 is arranged at the first pixel opening 1333. The first metal wiring 14 includes a first sub-line 141, and the second metal wiring 15 includes a second sub-line 151.

The orthographic projections of the third sub-line 142 and the fourth sub-line 152 on the plane where the first green pixel 1325 is located are located on opposite sides of the first green pixel 1325. The third minimum distance L5 between the third sub-line 142 and the second pixel opening 1334 is different from the fourth minimum distance L6 between the fourth sub-line 152 and the second pixel opening 1334.

Among them, the position setting of the third sub-line 142 and the fourth sub-line 152 can refer to the above-mentioned specific description of the first metal wiring 14 and the second metal wiring 15, and the present application will not repeat them here. For example, the third sub-line 142 is closer to the first display unit 11 or the second display unit 12 than the fourth sub-line 152. At this time, the third minimum distance L5 between the third sub-line 142 and the second pixel opening 1334 is set to be smaller than the fourth minimum distance L6 between the fourth sub-line 152 and the second pixel opening 1334.
[0065] See also Fig.11 , the pixel definition layer 131 is formed with a third pixel opening 1335, and the first blue pixel 1326 is arranged at the third pixel opening 1335. The first metal wiring 14 includes a fifth sub-line 143, and the second metal wiring 15 includes a sixth sub-line 153. The orthographic projections of the fifth sub-line 143 and the sixth sub-line 153 on the plane where the first blue pixel 1326 is located are located on opposite sides of the first blue pixel 1326. The fifth minimum distance L7 between the fifth sub-line 143 and the third pixel opening 1335 is different from the sixth minimum distance L8 between the sixth sub-line 153 and the third pixel opening 1335. It can be understood that the side where the metal wiring farther away from the third pixel opening 1335 is located can emit more blue light. Among them, the position setting of the fifth sub-line 143 and the sixth sub-line 153 can refer to the above-mentioned specific description of the first metal wiring 14 and the second metal wiring 15, and the present application will not repeat them here. For example, the fifth sub-line 143 is closer to the first display unit 11 or the second display unit 12 than the sixth sub-line 153. At this time, the fifth minimum distance L7 between the fifth sub-line 143 and the third pixel opening 1335 is set to be smaller than the sixth minimum distance L8 between the sixth sub-line 153 and the third pixel opening 1335.
[0066] Among them, according to the specific structure of the fold, the larger distance between the third minimum distance L5 and the fourth minimum distance L6 can be set to be larger than the larger distance between the first minimum distance L3 and the second minimum distance L4, and the larger distance between the fifth minimum distance L7 and the sixth minimum distance L8 can be set to be larger than the larger distance between the first minimum distance L3 and the second minimum distance L4, so as to balance the brightness attenuation of the first red pixel 1324, the first green pixel 1325 and the first blue pixel 1326 at a wide viewing angle, so as to improve the brightness difference and the color deviation difference of the viewing angle at the fold position.
[0067] For example, when the first minimum distance L3 between the first sub-line 141 and the first pixel opening 1333 is set to be smaller than the second minimum distance L4 between the second sub-line 151 and the first pixel opening 1333, the third minimum distance L5 between the third sub-line 142 and the second pixel opening 1334 is set to be smaller than the fourth minimum distance L6 between the fourth sub-line 152 and the second pixel opening 1334, and the fifth minimum distance L7 between the fifth sub-line 143 and the third pixel opening 1335 is set to be smaller than the sixth minimum distance L8 between the sixth sub-line 153 and the third pixel opening 1335, the fourth minimum distance L6 can be set to be larger than the second minimum distance L4, and the sixth minimum distance L8 can be set to be larger than the second minimum distance L4, so as to balance the brightness attenuation of the first red pixel 1324, the first green pixel 1325 and the first blue pixel 1326 at a wide viewing angle to improve the brightness difference at the crease position and the color deviation difference of the viewing angle.
