[0044] The display device of the embodiment of the present application includes a display panel of any embodiment of the first aspect. The angle range of the light emitted by the shared sub-pixel is greater than the angle range of the light emitted by the anti-peeping sub-pixel; therefore, when the shared sub-pixel is lit, the light emission range of the display panel can be expanded, and the light emission efficiency of the display panel can be improved, so that the main passenger seat set diagonally opposite to the display panel can also receive the light of the display panel and see the display content of the display panel. When the display panel is in the anti-peeping mode, only the anti-peeping sub-pixel is lit, and the light emitted by the anti-peeping sub-pixel has a longer optical path and a smaller angle, so that only the co-pixel set directly opposite to the display panel can be seen, and the main passenger seat is not visible; when the display panel is in the sharing mode, the anti-peeping sub-pixel and the shared sub-pixel are both lit, and the light emitted by the shared sub-pixel has a shorter optical path and a larger light emission angle, which expands the visible range of the display panel, so that the main passenger seat set diagonally opposite to the display panel can also be seen, and both the main passenger seat and the co-pixel can be seen. The display device of the embodiment of the present application can switch between anti-peeping mode and sharing mode, so that the co-pilot screen is visible to both the main driver and the co-pilot at the same time, and the main driver's visible mode (sharing mode) and invisible mode (anti-peeping mode) can be switched freely.

DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field based on this application belong to the scope of protection of the present invention.

[0062] With the rapid development of display technology, vehicle-mounted display panels have been widely used in automobiles. Vehicle-mounted display panels usually include a main driver's screen (FID), a central control screen (Car Information Display, CID) and a co-driver's screen (Co-Driver Display, CDD). In order to prevent the driver from being disturbed by the co-driver's screen during driving and causing safety hazards, the co-driver's screen is usually set to be invisible to the main driver and only visible to the co-driver. With the improvement of users' requirements for car usage experience, it is necessary to switch the co-driver's screen to the main driver under the premise of ensuring driving safety or when the car is in a stationary state. Therefore, how to make the co-driver's screen visible to both the main driver and the co-driver at the same time, and how to freely switch between the main driver's visible mode (sharing mode) and the invisible mode (anti-peeping mode) is a problem that technicians in this field urgently need to solve. In order to solve the above technical problems, the embodiments of the present application propose a display panel and a display device.

[0063] like Figure 1 As shown, Figure 1 This is a structural schematic diagram of a display panel of the first embodiment of the present application. The embodiment of the first aspect of the present application proposes a display panel, which includes a substrate 100 (Glass / PI), a light-emitting functional layer 200 and a driving circuit layer 300 (Array); the light-emitting functional layer 200 is arranged on one side of the substrate 100, including a plurality of anti-peeping sub-pixels P1 and a plurality of shared sub-pixels P2; the anti-peeping sub-pixel P1 includes an anti-peeping light-emitting unit 211; the shared sub-pixel P2 includes a shared light-emitting unit 212; the distance between at least a part of each shared light-emitting unit 212 and the substrate 100 is greater than the distance between the anti-peeping light-emitting unit 211 and the substrate 100; the driving circuit layer 300 is arranged between the substrate 100 and the light-emitting functional layer 200, including an anti-peeping driving circuit 310 and a shared driving circuit 320; the anti-peeping driving circuit 310 is used to drive the anti-peeping sub-pixel P1, and the shared driving circuit 320 is used to drive the shared sub-pixel P2.

[0064] The display panel of the embodiment of the present application includes a substrate 100, a light-emitting functional layer 200 and a driving circuit layer 300; the light-emitting functional layer 200 includes a plurality of anti-peeping sub-pixels P1 and a plurality of shared sub-pixels P2, the anti-peeping sub-pixel P1 includes an anti-peeping light-emitting unit 211, and the shared sub-pixel P2 includes a shared light-emitting unit 212; the distance between at least a portion of each shared light-emitting unit 212 and the substrate 100 is greater than the distance between the anti-peeping light-emitting unit 211 and the substrate 100, that is, the distance between part or all of each shared light-emitting unit 212 and the substrate 100 is greater than the distance between the anti-peeping light-emitting unit 211 and the substrate 100, so that at least a portion of the light-emitting path of the shared light-emitting unit 212 is shorter than the light-emitting path of the anti-peeping light-emitting unit 211, and the light-emitting efficiency is higher; Figure 2 As shown, Figure 2This is a light path diagram of a display panel according to the first embodiment of the present application. Figure 2 The dotted light in the figure respectively shows the maximum angles of the light emitted by the anti-peeping sub-pixel P1 and the shared sub-pixel P2. The angle range of the light emitted by the shared sub-pixel P2 is greater than the angle range of the light emitted by the anti-peeping sub-pixel P1. Therefore, when the shared sub-pixel P2 is illuminated, the light emitting range of the display panel can be expanded, and the light emitting efficiency of the display panel can be improved, so that the main driver who is set diagonally opposite to the display panel can also receive the light from the display panel and see the display content of the display panel.

[0065] The anti-peeping driving circuit 310 of the driving circuit layer 300 is used to drive the anti-peeping sub-pixel P1, and the shared driving circuit 320 is used to drive the shared sub-pixel P2, so as to realize the separate control of the anti-peeping sub-pixel P1 and the shared sub-pixel P2; when the display panel is in the anti-peeping mode, only the anti-peeping sub-pixel P1 is lit, and the light path of the light emitted by the anti-peeping sub-pixel P1 is longer and the angle is smaller, so that only the co-pixel that is directly opposite to the display panel is visible, and the main driver is invisible; when the display panel is in the sharing mode, the anti-peeping sub-pixel P1 and the shared sub-pixel P2 are both lit, and the light path of the light emitted by the shared sub-pixel P2 is shorter and the light angle is larger, so that the visible range of the display panel is expanded, so that the main driver that is diagonally opposite to the display panel is also visible, so that both the main driver and the co-pixel are visible. The display panel of the embodiment of the present application can be switched between the anti-peeping mode and the sharing mode, so that the co-pixel screen is visible to the main driver and the co-pixel at the same time, and the main driver visible mode (sharing mode) and invisible mode (anti-peeping mode) can be switched freely.

[0066] In the first embodiment of the present application, Figure 1 and Figure 2 As shown, the light-emitting function layer 200 further includes a pixel defining layer 220 (PDL); the pixel defining layer 220 has a plurality of pixel openings, and the plurality of pixel openings include a plurality of anti-peeping pixel openings 221 and a plurality of shared pixel openings 222; the plurality of anti-peeping pixel openings 221 define a plurality of anti-peeping sub-pixels P1, and the plurality of shared pixel openings 222 define a plurality of shared sub-pixels P2; a plurality of anti-peeping light-emitting units 211 are arranged in the plurality of anti-peeping pixel openings 221 in a one-to-one correspondence; and a plurality of shared light-emitting units 212 are arranged in the shared pixel openings 222 in a one-to-one correspondence. The plurality of pixel openings of the pixel defining layer 220 define a plurality of anti-peeping sub-pixels P1 and a plurality of shared sub-pixels P2 to define the size and arrangement of the anti-peeping sub-pixels P1 and the shared sub-pixels P2. The plurality of anti-peeping light-emitting units 211 and the plurality of anti-peeping shared light-emitting units 212 form a light-emitting layer (EL).

[0067] For the convenience of description, the side close to the substrate 100 is defined as "lower", and the side away from the substrate 100 is defined as "upper". The directional descriptions of "upper" and "lower" hereinafter are in accordance with the definitions herein.

[0068] like Figure 2 As shown, the distance between part of the shared light-emitting unit 212 and the upper edge of the shared pixel opening 222 is smaller than the distance between the anti-peeping light-emitting unit 211 and the upper edge of the anti-peeping pixel opening 221. In this way, the angle of the light emitted from the shared pixel opening 222 by the shared light-emitting unit 212 is greater than the angle of the light emitted from the anti-peeping pixel opening 221 by the peeping light-emitting unit 211.

[0069] In the first embodiment of the present application, Figure 1 and Figure 2 As shown, the area of ​​the orthographic projection of the shared pixel opening 222 on the substrate 100 is larger than the area of ​​the orthographic projection of the anti-peep pixel opening 221 on the substrate 100; the area of ​​the orthographic projection of the shared light-emitting unit 212 on the substrate 100 is larger than the area of ​​the orthographic projection of the anti-peep light-emitting unit 211 on the substrate 100. With such a configuration, the light emitted by the shared sub-pixel P2 is more than that emitted by the anti-peep sub-pixel P1, which is beneficial to improving the light emission efficiency. Correspondingly, the reflected light that cannot be directly emitted will also increase, which is beneficial to emitting more large-angle light, thereby facilitating the realization of the sharing mode.

[0070] In the first embodiment of the present application, Figure 1 and Figure 2 As shown, the light-emitting functional layer 200 also includes a first anode layer 230 (AND1) and a second anode layer 240 (AND2); the first anode layer 230 is arranged between the anti-peeping light-emitting unit 211 and the shared light-emitting unit 212 and the driving circuit layer 300, including multiple anti-peeping anodes 231 and multiple first shared anodes 232; the anti-peeping anode 231 is connected to the anti-peeping driving circuit 310, and is arranged in contact with the multiple anti-peeping light-emitting units 211 in a one-to-one correspondence; the first shared anode 232 is connected to the shared driving circuit 320; the second anode layer 240 is arranged between the shared light-emitting unit 212 and the first anode layer 230, including multiple second shared anodes 241; the multiple second shared anodes 241 are arranged in contact with the multiple shared light-emitting units 212 in a one-to-one correspondence, and are connected to the multiple first shared anodes 232 in a one-to-one correspondence. The second anode layer 240 is located on the side of the first anode layer 230 away from the substrate 100, and the multiple second shared anodes 241 of the second anode layer 240 are only arranged corresponding to the shared sub-pixel P2, and the shared light-emitting unit 212 is located on the side of the second anode layer 240 away from the substrate 100.

It should be noted that the projections of the vias and openings appearing in this article refer to the projections of the lower edges of the vias and openings on the substrate 100.

[0077] In the first embodiment of the present application, Figure 1 and Figure 2As shown, the orthographic projection of the shared pixel opening 222 on the substrate 100 covers the orthographic projection of the first shared via 252 on the substrate 100, which is beneficial to increase the contact area between the second shared anode 241 and the shared light-emitting unit 212, thereby increasing the light-emitting area of ​​the shared sub-pixel P2; the orthographic projection of the first shared via 252 on the substrate 100 covers the orthographic projection of the second shared via 332 on the substrate 100, so that the first shared via 252 and the second shared via 332 form a large hole-in-small hole arrangement, and the climbing distance and climbing height brought by the holes provide a longer path and deposition range for the second shared anode 241, thereby increasing the area of ​​the shared light-emitting unit 212, which is beneficial to improve the light output efficiency of the shared sub-pixel P2 and increase its light output angle.

[0078] like Figure 1 and Figure 2 As shown, the first shared anode 232 is connected to the first shared electrode 3211 through the second shared via 332. The first shared anode 232 is a uniform film layer, extending outward from the second shared via 332 along its hole wall, so that the first shared anode 232 includes a recessed portion 2321 located in the second shared via 332, and a flat portion 2322 located outside the second shared via 332; the climbing path of the second shared anode 241 is to climb over the recessed portion 2321 of the first shared anode 232 and the first shared via 252 in sequence.

[0079] In the first embodiment of the present application, Figure 1 and Figure 2 As shown, the first anti-peeping via 251 and the first shared via 252 are gradually expanded in the thickness direction of the display panel and in the direction away from the substrate 100; the hole wall of the first anti-peeping via 251 is sloped, and the taper angle is 30°; the hole wall of the first shared via 252 is sloped, and the taper angle is less than 30°. The taper angle of the first shared via 252 is smaller, so that the climbing distance of the second shared anode 241 and the shared light-emitting unit 212 is longer, which is conducive to increasing the area of ​​the second shared anode 241 and the shared light-emitting unit 212, thereby facilitating the realization of the sharing mode.

During the preparation of the display panel, the first anti-peeping via 251 of the first flat layer 250 partially exposes the anti-peeping anode 231. When preparing the second anode layer 240, the inflow of wet etching solution may cause the second ITO layer 2313 of the anti-peeping anode 231 exposed to the first anti-peeping via 251 to be etched and lost. To solve this problem, the thickness of the second ITO layer 2313 may be increased to resist the etching of this part when preparing the second anode layer 240, so as to ensure the normal operation of the anti-peeping sub-pixel P1.

[0082] Optionally, the metal layer 2312 is a silver (Ag) layer; the first shared anode 232 and the second shared anode 241 also include an ITO layer, an Ag layer and an ITO layer stacked in sequence in a direction away from the substrate 100; the thickness of the first shared anode 232 can be Among them, the thickness of the lower ITO layer is The thickness of the Ag layer is The thickness of the upper ITO layer is The thickness of the second shared anode 241 may be Among them, the thickness of the ITO layer is The thickness of the Ag layer is Since the peeking anode 231 and the first shared anode 232 are prepared in the same layer, the thickness of the first ITO layer 2311 is the same as the thickness of the lower ITO layer of the first shared anode 232 , and the thickness of the metal layer 2312 is the same as the Ag layer of the first shared anode 232 .

[0083] In the first embodiment of the present application, Figure 1 and Figure 2As shown, the light-emitting functional layer 200 further includes a spacer layer 400 (PS); the spacer layer 400 is arranged on the side of the pixel defining layer 220 away from the substrate 100; it includes a plurality of spacers 410, and the spacers 410 are arranged between two adjacent pixel openings; the display panel further includes an encapsulation layer 500 (TFE) and a black matrix 600 (BM); the encapsulation layer 500 is arranged on the side of the spacer layer 400 away from the substrate 100 to play a protective role; the black matrix 600 is arranged on the side of the encapsulation layer 500 away from the substrate 100; it includes a plurality of black matrix openings 610, and one black matrix opening 610 corresponds to one anti-peeping pixel opening 221 or one shared pixel opening 222. Optionally, the black matrix opening 610 corresponding to the anti-peeping sub-pixel P1 and the black matrix opening 610 corresponding to the shared sub-pixel P2 can be equal in size. The light-emitting functional layer 200 further includes a cathode layer (not shown in the figure). The cathode layer (cathode) is arranged on a side of the anti-peeping light-emitting unit 211 and the shared light-emitting unit 212 away from the substrate 100 and covers the spacer 410 .

[0084] like Figure 1 and Figure 2 As shown, the maximum angle of light emitted from the black matrix opening 610 by the anti-peep sub-pixel P1 is smaller than the maximum angle of light emitted from the black matrix opening 610 by the shared sub-pixel P2. The shared sub-pixel P2 provides light with a larger angle to be emitted from the display panel.

[0085] In the first embodiment of the present application, Figure 4 As shown, Figure 4 This is a light emission angle diagram of the display panel of the first embodiment of the present application, where the light emission angle perpendicular to the display panel is 0°; the display panel has an anti-peeping mode and a sharing mode; when the display panel is in the anti-peeping mode, only the anti-peeping sub-pixel P1 emits light, and the light emission angle of the display panel is ±25°; when the display panel is in the sharing mode, both the anti-peeping sub-pixel P1 and the shared sub-pixel P2 emit light, and the light emission angle of the display panel is ±40°. In the sharing mode, the shared sub-pixel P2 emits light, emitting more large-angle light, thereby expanding the light emission angle of the display panel from ±25° to ±40°, so that the driver can also receive the light emitted by the display panel, thereby achieving the visibility of the driver of the display panel.

Figure 71 is a schematic diagram of a display panel of the first embodiment of the present application when only the shared sub-pixel P2 is lit, the display panel includes a plurality of anti-peeping areas A1 and a plurality of shared areas A2; the plurality of anti-peeping areas A1 and the plurality of shared areas A2 are alternately arranged in a first direction; the anti-peeping sub-pixels P1 and the shared sub-pixels P2 are arranged in a matrix; the plurality of anti-peeping sub-pixels P1 are located in the anti-peeping area A1, including a red anti-peeping sub-pixel P11, a green anti-peeping sub-pixel P12 and a blue anti-peeping sub-pixel P13; the plurality of anti-peeping sub-pixels P1 are arranged in a plurality of anti-peeping sub-pixels along the second direction, with a red anti-peeping sub-pixel P11, a green anti-peeping sub-pixel P12 and a blue anti-peeping sub-pixel P13 arranged in sequence as a period. row; multiple shared sub-pixels P2 are located in the shared area A2, including a red shared sub-pixel P21, a green shared sub-pixel P22 and a blue shared sub-pixel P23; the multiple shared sub-pixels P2 are arranged into multiple rows along the second direction with a red shared sub-pixel P21, a green shared sub-pixel P22 and a blue shared sub-pixel P23 arranged in sequence as a period; the first direction, the second direction and the thickness direction of the display panel are perpendicular to each other; the first direction can be the length direction of the display panel, and the second direction is the width direction of the display panel; the first direction can also be the width direction of the display panel, and the second direction is the length direction of the display panel. That is, a red anti-peeping sub-pixel P11, a green anti-peeping sub-pixel P12 and a blue anti-peeping sub-pixel P13 form an anti-peeping pixel, and a red shared sub-pixel P21, a green shared sub-pixel P22 and a blue shared sub-pixel P23 form a shared pixel; a single anti-peeping pixel and the sub-pixels in a single shared pixel are arranged in a manner of 1r (row) * 3c (column); optionally, odd rows correspond to the anti-peeping mode and even rows correspond to the sharing mode. The anti-peeping area A1 and the sharing area A2 are alternately arranged in the first direction, so that the light output of the display panel is more uniform.

[0087] The display panel of the second embodiment of the present application is different from the display panel of the first embodiment of the present application in that the structure of the shared sub-pixel P2 is different.

[0088] In the second embodiment of the present application, Figure 8 and Fig. 9 As shown, Figure 8 is a schematic structural diagram of a display panel according to a second embodiment of the present application, Fig. 9This is a light path diagram of the display panel of the second embodiment of the present application. The orthographic projection of the shared pixel opening 222 on the substrate 100 covers the orthographic projection of the first shared via 252 on the substrate 100; the orthographic projection of the first shared via 252 on the substrate 100 is arranged at an interval from the orthographic projection of the second shared via 332 on the substrate 100. That is, the first shared via 252 is not above the first shared electrode 3211, ensuring that the second shared anode 241 contacts the first shared electrode 3211 through the first shared anode 232. At the same time, the second shared anode 241 is formed on the flat portion 2322 of the first shared anode 232 and is raised by the flat portion 2322 and the second flat layer 330, so that the distance between the entire second shared anode 241 and the substrate 100 is greater than the distance between the anti-peep anode 231 and the substrate 100, shortening the light emission path of the shared sub-pixel P2 and expanding the light emission range of the display panel.

[0089] Fig. 9 The dotted light rays in the figure respectively show the maximum angles of the light emitted by the anti-peeping sub-pixel P1 and the shared sub-pixel P2. The angle of the light emitted by the shared light-emitting unit 212 from the shared pixel opening 222 is greater than the angle of the light emitted by the peeping light-emitting unit 211 from the anti-peeping pixel opening 221. The maximum angle of the light emitted by the shared sub-pixel P2 from the black matrix opening 610 is greater than the maximum angle of the light emitted by the anti-peeping sub-pixel P1 from the black matrix opening 610. The angle range of the light emitted by the shared sub-pixel P2 is greater than the angle range of the light emitted by the anti-peeping sub-pixel P1. Therefore, when the shared sub-pixel P2 is illuminated, the light emitting range of the display panel can be expanded, and the light emitting efficiency of the display panel can be improved, so that the main driver who is set diagonally opposite to the display panel can also receive the light of the display panel and see the display content of the display panel.

[0090] The display panel of the third embodiment of the present application is different from the display panel of the second embodiment of the present application in that the structure of the driving circuit layer 300 is different. The display panel of the second embodiment of the present application has a single-layer source-drain metal layer, while the display panel of the third embodiment of the present application has three-layer source-drain metal layers.

Among them, the third anti-peeping electrode 3115, the fourth anti-peeping electrode 3116, the third shared electrode 3215 and the fourth shared electrode 3216 are arranged in the same layer to form a second source-drain metal layer, and the fifth anti-peeping electrode 3117, the sixth anti-peeping electrode 3118, the fifth shared electrode 3217 and the sixth shared electrode 3218 are arranged in the same layer to form a third source-drain metal layer. The second source-drain metal layer is arranged between the first source-drain metal layer and the gate layer, and the third source-drain metal layer is arranged between the second source-drain metal layer and the gate layer.

[0092] The first anti-peeping electrode 3111, the third anti-peeping electrode 3115 are connected, the fifth anti-peeping electrode 3117 is connected and the anti-peeping active layer 3114 is connected in sequence; the second anti-peeping electrode 3112, the fourth anti-peeping electrode 3116, the sixth anti-peeping electrode 3118 and the anti-peeping active layer 3114 are connected in sequence; the first shared electrode 3211, the third shared electrode 3215, the fifth shared electrode 3217 and the shared active layer 3214 are connected in sequence; the second shared electrode 3212, the fourth shared electrode 3216, the sixth shared electrode 3218 and the shared active layer 3214 are connected in sequence.

[0093] The driving circuit layer 300 also includes a third flat layer 360 and a fourth flat layer 370. The third flat layer 360 is arranged between the second source-drain metal layer and the first source-drain metal layer, and the fourth flat layer 370 is arranged between the second source-drain metal layer and the third source-drain metal layer. In the 3-layer SD (source-drain metal layer) design of the LTPO (low-temperature polycrystalline silicon and oxide) product, a PLN (flat layer) process is performed after each layer of the SD process to flatten the film layer. PLN is insulating in nature and can reduce bottom magnetic field interference and prevent light disorder.

[0094] It is understandable that in some other embodiments of the present application, the source-drain metal layer may also be a double layer, and the present application does not limit this.

The angle range of the light emitted by the shared sub-pixel P2 is greater than the angle range of the light emitted by the anti-peeping sub-pixel P1; therefore, when the shared sub-pixel P2 is lit, the light emission range of the display panel can be expanded, and the light emission efficiency of the display panel can be improved, so that the main passenger seat set diagonally opposite to the display panel can also receive the light of the display panel and see the display content of the display panel. When the display panel is in the anti-peeping mode, only the anti-peeping sub-pixel P1 is lit, and the light emitted by the anti-peeping sub-pixel P1 has a longer optical path and a smaller angle, so that only the co-pixel seated directly opposite to the display panel is visible, and the main passenger seat is invisible; when the display panel is in the sharing mode, the anti-peeping sub-pixel P1 and the shared sub-pixel P2 are both lit, and the light emitted by the shared sub-pixel P2 has a shorter optical path and a larger light emission angle, which expands the visible range of the display panel, so that the main passenger seat set diagonally opposite to the display panel is also visible, and both the main passenger seat and the co-pixel seat are visible. The display device of the embodiment of the present application can switch between anti-peeping mode and sharing mode, so that the co-pilot screen is visible to both the main driver and the co-pilot at the same time, and the main driver's visible mode (sharing mode) and invisible mode (anti-peeping mode) can be switched freely.
