The first electrode 200 is located on a first side of the substrate layer 100; the pixel definition layer 300 is located on a side of the first electrode 200 away from the substrate layer 100, and the pixel definition layer 300 is provided with a first opening penetrating the pixel definition layer 300; the liquid crystal layer 400 is located on a side of the first electrode 200 away from the substrate layer 100, and the liquid crystal layer 400 is divided into a plurality of pixels 410 by the pixel definition layer 300; the functional film layer 500 is located on a side of the liquid crystal layer 400 away from the substrate layer 100; the second electrode 600 is located on a side of the functional film layer 500 facing the liquid crystal layer 400, or, on a side of the substrate layer 100 facing the liquid crystal layer 400, and the second electrode 600 and the first electrode 200 are distributed relative to the ground on two sides opposite to the orthographic projection of the pixel 410 on the substrate layer 100.

[0056] The display panel further includes a first alignment layer 700 and a second alignment layer 800, or the display panel further includes a third electrode 900 and a fourth electrode 1000. The first alignment layer 700 and the second alignment layer 800 are respectively located on opposite sides of the liquid crystal layer 400, the third electrode 900 and the fourth electrode 1000 are respectively located on a side of the substrate layer 100 facing the liquid crystal layer 400 and / or on a side of the functional film layer 500 facing the liquid crystal layer 400, and when the third electrode 900 and / or the fourth electrode 1000 are located on a side of the substrate layer 100 facing the liquid crystal layer 400, the third electrode 900 and / or the fourth electrode 1000 are covered by the pixel definition layer 300.

[0057] In the display panel proposed in the embodiment of the present application, by simultaneously providing a first electrode 200, a second electrode 600, a first alignment layer 700 and a second alignment layer 800 in the display panel, or simultaneously providing a first electrode 200, a second electrode 600, a third electrode 900 and a fourth electrode 1000, based on the self-luminous characteristics of the light-emitting liquid crystal, the grayscale of each pixel 410 in the liquid crystal layer 400 can be adjusted by the first electrode 200 and the second electrode 600, or the grayscale of each pixel 410 in the liquid crystal layer 400 can be adjusted by the third electrode 900 and the fourth electrode 1000, so that the polarized light emitted by the light-emitting liquid crystal in the liquid crystal layer 400 can be regulated, and the purpose of grayscale regulation can be achieved while improving the brightness of the display panel.

[0058] Luminescent liquid crystals (LLCs) combine the orderliness of liquid crystals and the luminescence properties of chromophore molecules. Luminescent liquid crystal molecules can achieve various complex orientations under the action of external forces and emit different polarized light. For linearly polarized luminescent materials prepared from luminescent liquid crystal polymers, it is usually only necessary to reasonably modify the liquid crystal unit and achieve uniaxial orientation of the liquid crystal unit under the condition of applying an external field to construct. In the display panel proposed in the embodiment of the present application, Figures 3 to 15 As shown, the liquid crystal layer 400 includes light-emitting liquid crystals, and the orientation of the light-emitting liquid crystals is adjusted by the voltage difference between the first electrode 200 and the second electrode 600 or by the voltage difference between the third electrode 900 and the fourth electrode 1000, that is, a voltage external field is applied to the light-emitting liquid crystals, so that the orientation of the light-emitting liquid crystals can be changed, thereby avoiding or reducing the light emitted by the light-emitting liquid crystals passing through the polarizer in the functional film layer 500, reducing the loss of light emitted by the light-emitting liquid crystals, thereby improving the luminous efficiency and brightness of the display panel, and further extending the service life of the display panel.

In addition, by adjusting the polarization direction of the polarized light emitted by the liquid crystal, the field of view of the display panel can be adjusted to achieve the purpose of anti-peeping.

[0060] Based on the same inventive concept, the embodiment of the present application also provides a display device, which includes the above-mentioned display panel. The display device can be applied to any product or component with display function, such as a television, a monitor, a notebook computer, a tablet computer, a mobile phone, a digital photo frame, a watch, etc.

[0061] Since the display device provided by the present invention includes the display panel of the above technical solution, the display device provided by the present invention has all the beneficial effects of the above display panel, which will not be described in detail here.

[0062] In some embodiments, Figure 1As shown, the display device includes a display area 10 and a non-display area 20, wherein the display area 10 is used to display graphics, and the display area 10 is composed of an array of pixel units 30. The non-display area 20 is used to place control circuits and electronic components. The display area 10 and the non-display area 20 can be rectangular, circular, elliptical or spline curves, etc. The display area 10 can also be located inside or outside the non-display area 20, or an area greater than or equal to the non-display area 20 can be arranged inside the display area 10 for placing control circuits and electronic components. For example, the non-display area 20 can be used to place GOA circuits, auxiliary structures (such as packaged DAM, crack DAM, etc.), flexible circuit boards (FPCs), chips (ICs) and other structures.

[0063] In some embodiments, each pixel unit 30 may include Figure 2 The 2T1C pixel 410 circuit, the light-emitting element, and the pixel 410 corresponding to the light-emitting element are shown. In the following embodiments of the present application, the light-emitting element takes OLED as an example to exemplify the display panel of the present application. Each pixel unit 30 has a switching TFT (STFT) and a driving TFT (DTFT) in the circuit. The driving TFT (DTFT) is used to drive the light-emitting element to emit light, and its output characteristics and the leakage of the switching TFT (STFT) have a great influence on the display effect.

[0064] In other embodiments, the number of TFTs and capacitors may also be greater than or equal to 2.

[0065] In some embodiments, the functional film layer 500 may include a packaging layer, a polarizer, etc. The functional film layer 500 may be adaptively adjusted according to the display effect requirements of the light-emitting side P1 of the display panel, which will not be described in detail here.

[0066] In some embodiments, the display panel may be a twisted nematic (TN) display panel.

[0067] In some other embodiments, the display panel may be an In-Plane-Switching (IPS) display panel.

[0068] In the above embodiment, the pixel definition layer 300 can define the area of ​​the pixel 410, and the pixel definition layer 300 is provided with a plurality of first openings penetrating the pixel definition layer 300, and each first electrode 200 and / or second electrode 600 can be exposed through the first opening, so that the liquid crystal layer 400 can be in contact with the first electrode 200 and / or the second electrode 600, and the luminescent liquid crystal in the liquid crystal layer 400 can emit light through the first electrode 200 and the second electrode 600.

[0069] In some embodiments, Figure 3As shown, a cross-sectional schematic diagram of a display panel including two sub-pixels 410 is shown, and the display panel includes a first alignment layer 700 and a second alignment layer 800, and the first alignment layer 700 and the second alignment layer 800 are respectively located on opposite sides of the liquid crystal layer 400. Taking the display panel adopting the IPS mode as an example, the liquid crystal layer 400 can be made to have a certain orientation through the first alignment layer 700 and the second alignment layer 800, and the gray scale of the pixel 410 is regulated by controlling the voltage difference between the first electrode 200 and the second electrode 600, that is, by controlling the current between the first electrode 200 and the second electrode 600, when the polarized light emitted by the light-emitting liquid crystal in the liquid crystal layer 400 is made consistent with the polarization direction of the polarizer in the functional film layer 500, the light loss emitted by the light-emitting liquid crystal of each pixel 410 is minimal, the luminous efficiency and brightness can be improved, and the life span can be improved accordingly.

[0070] In some embodiments, the display panel further includes a third electrode 900 and a fourth electrode 1000, which are respectively located on a side of the substrate layer 100 facing the liquid crystal layer 400 and / or on a side of the functional film layer 500 facing the liquid crystal layer 400. Figure 4 As shown, a cross-sectional schematic diagram of a display panel including two sub-pixels 410 is shown. When the third electrode 900 and / or the fourth electrode 1000 are located on the side of the substrate layer 100 facing the liquid crystal layer 400, that is, the third electrode 900 and the fourth electrode 1000 are in the same plane, the third electrode 900 and / or the fourth electrode 1000 are covered by the pixel definition layer 300 to isolate the third electrode 900 or the fourth electrode 1000 from the liquid crystal layer 400. Taking the display panel adopting the IPS mode as an example, the liquid crystal layer 400 can be oriented to a certain extent by the third electrode 900 and the fourth electrode 1000, and the gray scale of the pixel 410 is regulated by controlling the voltage difference between the first electrode 200 and the second electrode 600, that is, by controlling the current between the first electrode 200 and the second electrode 600. When the polarized light emitted by the light-emitting liquid crystal in the liquid crystal layer 400 is consistent with the polarization direction of the polarizer in the functional film layer 500, the light loss emitted by the light-emitting liquid crystal of each pixel 410 is minimal, the luminous efficiency and brightness can be improved, and the life span can be improved accordingly. In these embodiments, Figure 4 As shown, two adjacent sub-pixels 410 may share the fourth electrode 1000 located therebetween.

[0071] In some embodiments, Figure 4, a cross-sectional schematic diagram of a display panel including two sub-pixels 410 is shown, and the display panel further includes a third electrode 900 and a fourth electrode 1000, and the third electrode 900 and the fourth electrode 1000 are respectively located on the side of the substrate layer 100 facing the liquid crystal layer 400 and / or on the side of the functional film layer 500 facing the liquid crystal layer 400. When the third electrode 900 and / or the fourth electrode 1000 are located on the side of the substrate layer 100 facing the liquid crystal layer 400, the third electrode 900 and / or the fourth electrode 1000 are covered by the pixel definition layer 300 to isolate the third electrode 900 or the fourth electrode 1000 from the liquid crystal layer 400. Taking the display panel using the IPS mode as an example, the voltage difference between the first electrode 200 and the second electrode 600 is controlled to make the current between the first electrode 200 and the second electrode 600 constant to ensure the brightness of the light-emitting liquid crystal in the liquid crystal layer 400, and the voltage difference between the third electrode 900 and the fourth electrode 1000 is controlled, that is, the current between the third electrode 900 and the fourth electrode 1000 is controlled to adjust the light-emitting liquid crystal in the liquid crystal layer 400 to have a certain orientation, so that the polarized light emitted by the light-emitting liquid crystal in the liquid crystal layer 400 and the polarization direction of the polarizer in the functional film layer 500 are adjusted, and only the component of the polarized light emitted by the light-emitting liquid crystal in the liquid crystal layer 400 in the polarization direction of the polarizer in the functional film layer 500 can be emitted, that is, the gray scale of the pixel 410 is adjusted by the third electrode 900 and the fourth electrode 1000, which can avoid the defect of instability of small current (low gray scale) between the first electrode 200 and the second electrode 600. In these embodiments, as Figure 4 As shown, two adjacent sub-pixels 410 may share the fourth electrode 1000 located therebetween.

[0072] In some embodiments, Figure 5As shown, a cross-sectional schematic diagram of a display panel including two sub-pixels 410 is shown, and the display panel also includes a first alignment layer 700, a second alignment layer 800, a third electrode 900 and a fourth electrode 1000. The first alignment layer 700 and the second alignment layer 800 are respectively located on opposite sides of the liquid crystal layer 400, and the third electrode 900 and the fourth electrode 1000 are respectively located on the side of the substrate layer 100 facing the liquid crystal layer 400 and / or on the side of the functional film layer 500 facing the liquid crystal layer 400. Taking the display panel adopting the IPS mode as an example, the liquid crystal layer 400 can be oriented to a certain extent by the first alignment layer 700 and the second alignment layer 800; the current between the first electrode 200 and the second electrode 600 is kept constant by controlling the voltage difference between the first electrode 200 and the second electrode 600 to ensure the brightness of the light-emitting liquid crystal in the liquid crystal layer 400; the voltage difference between the third electrode 900 and the fourth electrode 1000 is controlled, that is, the current between the third electrode 900 and the fourth electrode 1000 is controlled to adjust the brightness of the light-emitting liquid crystal in the liquid crystal layer 400. The orientation of the polarized light emitted by the luminescent liquid crystal in the liquid crystal layer 400 and the polarization direction of the polarizer in the functional film layer 500 are regulated, and only the component of the polarized light emitted by the luminescent liquid crystal in the liquid crystal layer 400 in the polarization direction of the polarizer in the functional film layer 500 can be emitted. At this time, the brightness of the pixel 410 is regulated by the orientation of the luminescent liquid crystal, that is, the third electrode 900 and the fourth electrode 1000, that is, the grayscale of the pixel 410 is regulated by the third electrode 900 and the fourth electrode 1000, which can avoid the defect of instability of small current (low grayscale) between the first electrode 200 and the second electrode 600. In these embodiments, as Figure 4 As shown, two adjacent sub-pixels 410 may share the fourth electrode 1000 located therebetween.

The third electrode 900 may be controlled by the pixel 410 circuit disposed in the substrate layer 100, and the fourth electrode 1000 may include an insulating layer and a second alignment layer 800, so that the fourth electrode 1000 may be used as a common electrode.

[0074] In some embodiments, taking the display panel adopting the TN mode as an example, that is, the electrodes used to control the orientation of the liquid crystal are not in the same plane, the current between the first electrode 200 and the second electrode 600 can be controlled to be constant by controlling the voltage difference between the first electrode 200 and the second electrode 600 to ensure the brightness of the luminous liquid crystal in the liquid crystal layer 400. By controlling the voltage difference between the third electrode 900 and the fourth electrode 1000, the luminous liquid crystal in the liquid crystal layer 400 is regulated to have a certain orientation to regulate the gray scale of the pixel 410. The principle is the same as that in the aforementioned embodiment and will not be repeated here.

[0075] In some other embodiments, taking the display panel adopting the TN mode as an example, that is, the electrodes used to control the orientation of the liquid crystal are not in the same plane, the voltage difference between the first electrode 200 and the second electrode 600 can be controlled to regulate the current between the first electrode 200 and the second electrode 600, so as to control the gray scale of the pixel 410. At the same time, the voltage difference between the third electrode 900 and the fourth electrode 1000 can be controlled to make the liquid crystal layer 400 have a certain orientation. The principle is the same as that of the aforementioned embodiment and will not be repeated here.
