Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display, and particularly relates to a display panel and a display device. BACKGROUND

[0002] In the display field, various technologies are currently competing with each other, and the competition is fierce. The most representative of them are OLED (Organic Light-Emitting Diode), LCD (Liquid Crystal Display) and Mini LED (Mini Light-Emitting Diode display technology). Among the three, the LCD technology is more traditional, which uses a liquid crystal layer as a display layer, adjusts the arrangement of liquid crystal molecules to control the transmission of light, and thus realizes image display. Its advantages are low cost, wide viewing angle and strong color restoration capability. Mini LED is a modified form of LCD, which uses smaller backlights, so that the backlights can be arranged more densely, thereby realizing higher brightness and more precise local dimming. The advantage of OLED is its self-luminous characteristic, which makes its color performance very good, with bright colors, high contrast and pure black performance. At the same time, since the pixel points self-luminesce, there is no need for a backlight, so the OLED television can be made thinner and more design-oriented. However, due to advanced display technology and high-cost production process, the price of OLED television is generally high.

[0003] In the prior art, the brightness and lifetime of the organic light-emitting material in the display panel using OLED technology have always been a difficult problem, which limits the rapid development of OLED. Among the red, green and blue organic light-emitting materials, the blue light-emitting material is particularly limited by the material itself, and the lifetime problem is particularly serious, which may cause premature brightness decline and lifetime reduction. The current solution is to increase the aperture ratio (size, area) of the blue organic material, but this will correspondingly reduce the aperture ratio of other colors and increase the use cost of the blue organic light-emitting material.

[0004] In summary, the organic light-emitting material in the OLED display panel currently used may prematurely cause brightness decline and lifetime reduction. SUMMARY

[0047] In a first aspect, as shown in the drawings, the present application provides a display panel 10, comprising a substrate 11, an insulating layer 12, an anode layer 13 and a first uniform layer 14 arranged in sequence, the display panel 10 has a display area 200 and a non-display area 100, the display area 200 is arranged in an array and is spaced apart, and the non-display area 100 is arranged in the space between the display areas 200; Figures 1 to 4 In the non-display area 100: a one-way light transmission layer 101 and a first filter layer 102 are arranged between the substrate 11 and the insulating layer 12, the one-way light transmission layer 101 is arranged on the side of the substrate 11 close to the insulating layer 12, the first filter layer 102 is arranged on the side of the one-way light transmission layer 101 close to the insulating layer 12, and a first guide layer 103 is further arranged between the anode layer 13 and the first uniform layer 14;

[0048] In the display area 200: a second filter layer 201 is arranged between the substrate 11 and the insulating layer 12, the second filter layer 201 is used for passing at least one of three primary colors, and an organic light emitting layer 202 is further arranged between the anode layer 13 and the first uniform layer 14;

[0049]

[0050] ​The organic light-emitting layer 202 is configured to emit white light or at least one of three primary colors, and the first filter layer 102 is configured to allow light of the same wavelength as the light emitted by the organic light-emitting layer 202 to pass through.

[0051] The display panel 10 provided by the present application uses ambient light to enter the display panel 10 from the non-display area 100, and converts the ambient light into light of the same wavelength as the light emitted by the organic light-emitting layer 202, including at least one of white light, red light, green light, and blue light, through the unidirectional light transmission layer 101 and the first filter layer 102. In this way, the light emitted by the organic light-emitting layer 202 can be mixed, thereby enhancing the brightness. Moreover, the use of the organic light-emitting layer 202 can be reduced, that is, the power consumption is reduced, thereby prolonging the service life. Then, the light is emitted through the second filter layer 201 to achieve the display effect.

[0052] In some embodiments, in at least one display area 200: the second filter layer 201 has the same effect as the corresponding first filter layer 102, the second uniform layer 203 is arranged between the anode layer 13 and the organic light-emitting layer 202, the second uniform layer 203 extends into the non-display area 100 adjacent to the display area 200, one end of the second uniform layer 203 abuts against the first guide layer 103, the second uniform layer 203 is located in the non-display area 100, the second guide layer 104 is arranged between the second uniform layer 203 and the first uniform layer 14, and the reflective layer 105 is arranged at the position of the first uniform layer 14 corresponding to the second guide layer 104.

[0053] The light path diagram of the display panel 10 is shown in FIG. 1, taking the example that the first filter layer 102 allows only blue light to pass through, the organic light-emitting layer 202 emits blue light, and the second filter layer 201 is a blue filter layer 2013. Figure 1 The external ambient light first passes through the unidirectional light transmission layer 101 in the non-display area 100, enters the first filter layer 102 for filtering, and only blue light in the external ambient light enters the display panel 10, and then is guided to the first uniform layer 14 through the first guide layer 103. The light is uniformly reflected to the first guide layer 103 through the reflective layer 105 after being uniformly reflected, and is guided to the second uniform layer 203, and is mixed and uniformly emitted with the blue light emitted by the organic light-emitting layer 202, and then is emitted to the second filter layer 201, and finally the blue light is emitted. Figure 6 As shown in FIG. 2, by analogy, when the first filter layer 102 allows only red light to pass through, the organic light-emitting layer 202 emits red light, and the second filter layer 201 is a red filter layer 2011, the red light is enhanced. Figure 5 As shown in FIG. 3, by analogy, when the first filter layer 102 allows only green light to pass through, the organic light-emitting layer 202 emits green light, and the second filter layer 201 is a green filter layer 2012, the green light is enhanced.

[0054] In other embodiments, the red filter layer 2011, the green filter layer 2012 and the blue filter layer 2013 can also exist in the same display panel 10 at the same time, and the plurality of organic light-emitting layers 202 respectively emit red light, green light, blue light and white light. In this way, the brightness of light of the corresponding color can be simultaneously enhanced, thereby reducing the power consumption of the corresponding color organic light-emitting material and thereby improving the service life.

[0055] In application, the substrate 11 is usually a glass substrate 11, mainly as a coated substrate 11, which plays a role of bearing; the insulating layer 12 plays a role of protecting and flattening the surface of the organic light resistance of the lower layer (the first filter layer 102 and the second filter layer 201); the anode layer 13 is usually a transparent ITO-anode, which is used for display current transmission and generates holes in the OLED panel; the first uniform layer 14 receives the light source and randomly reflects the light in the layer to form uniform light; the unidirectional light transmission layer 101, as the name implies, its role is to allow light to pass through only in one direction. Even if the external environmental light enters the display panel 10 through the unidirectional light transmission layer 101; the first filter layer 102 is used to filter the external environmental light, only part of the light enters the display panel 10, specifically, it is the light of the same wavelength as the light emitted by the organic light-emitting layer 202 in the white light and the three primary colors, that is, at least one of the three primary colors; the first guide layer 103 plays a role of standardizing and guiding the light source light, that is, directing the external environmental light to the first uniform layer 14; the second filter layer 201 is used to filter out light other than the three primary colors, that is, only one of the three primary colors is allowed to pass through, and then the display area 200 emits light to display the corresponding color, such as Figures 3 to 6 As shown, it usually includes three kinds, that is, the red filter layer 2011, the green filter layer 2012 and the blue filter layer 2013; the organic light-emitting layer 202 is used to assist the generation and transmission of holes and electrons to the light-emitting layer, excitation and light emission; the reflection layer 105 is used to reflect the light that has been uniformly reflected by the first uniform layer 14 to the second guide layer 104, and then through the second uniform layer 203 again, the light is emitted through the second filter layer 201, the second guide layer 104 has the same effect as the first guide layer 103, and the second uniform layer 203 has the same effect as the first uniform layer 14; the second filter layer 201 and the first filter layer 102 have the same effect.

[0056] It is important to further understand that the meaning of "the second filter layer 201 and the first filter layer 102 have the same function" is not only about filtering light, but also includes that the color and wavelength of the light allowed to pass through the second filter layer 201 are consistent with those allowed by the first filter layer 102. That is, when the first filter layer 102 allows white light to pass through, the second filter layer 201 also allows white light to pass through; when the first filter layer 102 only allows blue light to pass through, the second filter layer 201 also only allows blue light to pass through; when the first filter layer 102 only allows red light to pass through, the second filter layer 201 also only allows red light to pass through; and when the first filter layer 102 only allows green light to pass through, the second filter layer 201 also only allows green light to pass through.

[0057] In some embodiments, such as Figure 1 and Figure 4 As shown, the display panel 10 forms a pixel unit in every three adjacent display areas 200, and the pixel unit includes three sub-pixel units for displaying red light, green light and blue light respectively;

[0058] The organic light-emitting layer 202 is used to emit white light. In any pixel unit, the color displayed by the sub-pixel unit is the same as the color of the light allowed to pass through the second filter layer 201. In the display area 200: a second uniform layer 203 is provided between the corresponding anode layer 13 and the organic light-emitting layer 202, and the second uniform layer 203 extends into the non-display area 100 adjacent to the display area 200. One end of the second uniform layer 203 abuts against the first guide layer 103 and is located in the non-display area 100. A second guide layer 104 is provided between the second uniform layer 203 and the first uniform layer 14. A reflective layer 105 is provided at the position of the first uniform layer 14 corresponding to the second guide layer 104.

[0059] In this way, the white light emitted by the organic light-emitting layer 202 in the sub-pixel unit can be enhanced according to the three primary colors red, green and blue respectively, so as to improve the brightness of each pixel.

[0060] It should be noted that the sub-pixel units are arranged in RGB, that is, the arrangement of the three primary colors of red, green and blue. The advantage of this method is that the colors are accurate and the brightness is high.

[0061] In some embodiments, such as Figure 4 As shown, within the red-emitting sub-pixel unit: the area of ​​the corresponding first uniform layer 14 is S. R ;

[0062] Within the green-emitting sub-pixel unit: the area of ​​the corresponding first uniform layer 14 is S. G ;

[0063] Within the blue-light-emitting sub-pixel unit: the area of ​​the corresponding first uniform layer 14 is S. B ;

[0064] S B S R S G .

[0065] In application, in the three primary color lights, the brightness of blue is the lowest, and the brightness of green is the highest, so the area of the first uniform layer 14 is set according to the characteristics of different color light emitting materials, that is, S B S R S G In this way, the receiving area of blue light can be maximized, and the brightness of blue light can be maximized to the greatest extent, the receiving area of green light is the smallest, and the receiving area of red light is the second; in this way, the final display effect can be color-uniform, and the best display effect can be achieved.

[0066] In an embodiment, as shown in Figure 1 , the first filter layer 102 only allows blue light to pass through, and in at least one display area 200: the second filter layer 201 only allows blue light to pass through, and the organic light emitting layer 202 is used to emit blue light. In this way, the brightness of blue light can be effectively improved, the power consumption of the blue light emitting material can be reduced, and the service life thereof can be improved.

[0067] In another embodiment, as shown in Figure 5 , the first filter layer 102 only allows green light to pass through, and in at least one display area 200: the second filter layer 201 only allows green light to pass through, and the organic light emitting layer 202 is used to emit green light.

[0068] In yet another embodiment, as shown in Figure 6 , the first filter layer 102 only allows red light to pass through, and in at least one display area 200: the second filter layer 201 only allows red light to pass through, and the organic light emitting layer 202 is used to emit red light.

[0069] In some embodiments, as shown in Figure 1 and Figure 4 , from one end of the anode layer 13 to one end of the first uniform layer 14, at least one side of the first guide layer 103 gradually narrows towards the middle part of the first guide layer 103. The external ambient light can enter the first uniform layer 14 as quickly and as much as possible, and the brightness can be effectively improved.

[0070] In application, as shown in Figure 1 and Figure 4As shown, the first guiding layer 103 gradually narrows from one end close to the anode layer 13 to one end of the first uniform layer 14: one side of the first guiding layer 103 gradually narrows towards the middle of the first guiding layer 103. In this way, the other side of the first guiding layer 103 is facilitated to abut against the organic light-emitting layer 202, facilitating fabrication. Preferably, the first guiding layer 103 gradually narrows from one end close to the anode layer 13 to one end of the first uniform layer 14: both sides of the first guiding layer 103 gradually narrow towards the middle of the first guiding layer 103. In this way, external ambient light is facilitated to be quickly guided into the first uniform layer 14.

[0071] In some embodiments, as shown in Figure 1 and Figure 4 As shown, the second guiding layer 104 gradually increases from one end close to the anode layer 13 to one end of the first uniform layer 14: at least one side of the second guiding layer 104 gradually increases towards the middle of the first guiding layer 103.

[0072] In application, as shown in Figure 1 As shown, the second guiding layer 104 gradually increases from one end close to the anode layer 13 to one end of the first uniform layer 14: one side of the second guiding layer 104 gradually increases towards the middle of the second guiding layer 104. In this way, the other side of the second guiding layer 104 is facilitated to abut against the organic light-emitting layer 202, facilitating fabrication. Preferably, the second guiding layer 104 gradually narrows from one end close to the anode layer 13 to one end of the first uniform layer 14: both sides of the second guiding layer 104 gradually narrow towards the middle of the second guiding layer 104. In this way, external ambient light is facilitated to be quickly guided into the first uniform layer 14.

[0073] In application, the first guiding layer 103 and the second guiding layer 104 are connected, and in the gap between adjacent sub-pixel units, which is conducive to the preparation of the overall display panel 10, and a compact display panel 10 can be obtained.

[0074] In some embodiments, as shown in Figure 1 As shown, a gap exists between the first guiding layer 103 and the organic light-emitting layer 202 adjacent thereto. In this way, the light emitted by the organic light-emitting layer 202 can be effectively prevented from interfering with the light in the first guiding layer 103.

[0075] In some embodiments, as shown in Figure 1 As shown, the organic light-emitting layer 202 includes a hole injection layer 2021, a hole transport layer 2022, a sub-light-emitting layer 2023, an electron transport layer 2024, an electron injection layer 2025, and a cathode layer 2026, which are sequentially stacked, wherein the cathode layer 2026 is arranged close to the first uniform layer 14, and the hole injection layer 2021 is arranged close to the anode layer 13.

[0076] In the application, the sub light-emitting layer 2023 is prepared by using an organic light-emitting material, including at least one of a blue light-emitting material, a red light-emitting material, a green light-emitting material, and a white light-emitting material. One of the sub light-emitting layers 2023 corresponds to one material. The hole injection layer 2021 is used for hole injection generated by current; the hole transport layer 2022 is used for assisting efficient hole transport; the photons in the sub light-emitting layer 2023 are excited by combining with electrons and emit light (R / G / B three colors), different excitation materials correspond to different excitation light; the electron transport layer 2024 is used for assisting efficient electron transport; the electron injection layer 2025 is used for electron injection generated by current; and the cathode layer is used for OLED panel display current transmission and electron generation.

[0077] In a second aspect, the present application provides a display device, such as Figure 7 As shown in the figure, the display device comprises the display panel 10 and the base 20.

[0078] The display device provided by the embodiment of the present application can utilize the external ambient light and convert it into corresponding light emitted by the organic light-emitting material, thereby improving the brightness of the corresponding light and reducing the power consumption of the organic light-emitting material, so as to improve the service life.

[0079] It should be noted that, among the three kinds of organic light-emitting materials of red, green, and blue, the service life of the blue light-emitting material is particularly serious due to the limitation of the material itself, and problems such as brightness reduction and service life reduction may occur in advance. Therefore, the first filter layer 102 is arranged to only allow blue light to pass through, and the organic light-emitting layer 202 in the display panel 10 is used to emit blue light, so as to enhance the brightness of the blue light in the display panel 10, and under the same blue light brightness condition, compared with the existing display panel 10, the power consumption of the organic light-emitting layer 202 of the display panel 10 is effectively reduced, so as to effectively improve the service life and solve the problems of brightness reduction and service life reduction of the blue organic light-emitting material.
