Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background Art

[0002] In the display field, there are currently many technologies that are catching up with each other and the competition is fierce. The most representative ones are OLED (Organic Light-Emitting Diode), LCD (Liquid Crystal Display) and Mini LED (Mini Light-Emitting Diode, sub-millimeter light-emitting diode display technology). Among the three, LCD technology is more traditional, using a liquid crystal layer as the display layer, and controlling the transmission of light by adjusting the arrangement of liquid crystal molecules to achieve image display. Its advantages are low cost, wide viewing angle, and strong color reproduction ability. Mini LED is a modified form of LCD, using a smaller backlight, so that the backlight can be arranged more densely, thereby achieving higher brightness and finer local dimming. The advantage of OLED is that its self-luminous characteristics make its color performance very outstanding, with bright colors, high contrast, and pure black performance. At the same time, because the pixels are self-luminous and do not require a backlight source, it can be made thinner and more design-oriented. However, due to advanced display technology and high-cost production processes, the price of OLED TVs is generally high.

[0003] In the prior art, the brightness and lifespan of the organic light-emitting materials in the display panels using OLED technology have always been a difficult problem, which has limited the rapid development of OLED. Among the three types of organic light-emitting materials, red, green and blue, the blue-light-emitting materials are particularly limited by the materials themselves, and the lifespan problem is particularly serious, which will lead to problems such as brightness drop and lifespan reduction in advance. The current solution is to increase the aperture ratio (size, area) of the blue light organic material, but this will correspondingly reduce the aperture ratios of other colors and increase the cost of using the blue light organic material.

[0004] In summary, the organic light-emitting materials in the current OLED display panels will experience problems such as decreased brightness and reduced lifespan prematurely during use. Summary of the invention

[0011] In some embodiments, the display panel forms a pixel unit in every three adjacent display areas, and the pixel unit includes three sub-pixel units for displaying red light, green light, and blue light respectively;

[0012] The organic light-emitting layer is used to emit white light. In any one of the pixel units, 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. In the display area: the second uniform layer is provided between the corresponding anode layer and the organic light-emitting layer, and the second uniform layer extends to the non-display area adjacent to the display area, and one end of the second uniform layer abuts against the first guide layer and is located in the non-display area, the second guide layer is provided between the second uniform layer and the first uniform layer, and the reflective layer is provided at a position of the first uniform layer corresponding to the second guide layer.

[0047] First, as Figures 1 to 4 As shown, 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 which are stacked in sequence, the display panel 10 having a display area 200 and a non-display area 100, the display area 200 is in an array and arranged at intervals, and the non-display area 100 is arranged in the intervals of the display area 200;

[0048] Located in the non-display area 100: a one-way light-transmitting layer 101 and a first light-filtering layer 102 are provided between the substrate 11 and the insulating layer 12, the one-way light-transmitting layer 101 is provided on a side of the substrate 11 close to the insulating layer 12, the first light-filtering layer 102 is provided on a side of the one-way light-transmitting layer 101 close to the insulating layer 12, and a first guide layer 103 is provided between the anode layer 13 and the first uniform layer 14;

[0049] Located in the display area 200: a second filter layer 201 is provided between the substrate 11 and the insulating layer 12, and the second filter layer 201 is used to allow at least one of the three primary colors of light to pass through, and an organic light-emitting layer 202 is also provided between the anode layer 13 and the first uniform layer 14;

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

[0051] The display panel 10 provided in the present application utilizes external ambient light to enter the display panel 10 from the non-display area 100, and converts the external ambient light into light with the same wavelength as the light emitted by the organic light-emitting layer 202 through the unidirectional light-transmitting layer 101 and the first filter layer 102; in this way, the light can be mixed with the light emitted by the organic light-emitting layer 202 to enhance the brightness; and the use of the organic light-emitting layer 202 can be reduced, that is, the power consumption is reduced and the life is increased; and 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 function as the corresponding first filter layer 102, a second uniform layer 203 is provided between the anode layer 13 and the organic light-emitting layer 202, the second uniform layer 203 extends into a non-display area 100 adjacent to the display area 200, and 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, and a reflective layer 105 is provided at a 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 as follows Figure 1 As shown, taking the first filter layer 102 as an example in which only blue light passes through, the organic light emitting layer 202 emits blue light, and the second filter layer 201 is a blue filter layer 2013; the external ambient light first passes through the one-way light-transmitting layer 101 in the non-display area 100, enters the first filter layer 102 for filtering, and only the blue light in the external ambient light enters the display panel 10, and then passes through the first guide layer 103 to guide the first uniform layer 14, and then the randomly reflected light is evenly reflected through the reflective layer 105 to the first guide layer 103 and emitted to the second uniform layer 203, and at the same time, after being evenly mixed with the blue light emitted by the organic light emitting layer 202, it is emitted to the second filter layer 201, and finally the blue light is emitted; as shown in FIG. Figure 6 As shown, similarly, 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 ultimately enhanced; Figure 5 As shown, similarly, when the first filter layer 102 only allows 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 red light is finally enhanced.

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

[0055] In application, the substrate 11 is usually a glass substrate 11, which is mainly used as a coating substrate 11 and plays a bearing role; the insulating layer 12 protects the organic photoresist of the lower layer (the first filter layer 102 and the second filter layer 201) and flattens the film surface; the anode layer 13 is usually a transparent ITO-anode, which is used for display current transmission in the OLED panel to generate holes; the first uniform layer 14 receives the light source and reflects the light in the layer to form uniform light; the unidirectional transparent layer 101, as the name suggests, only allows light to pass in one direction. Even if the external ambient light enters the display panel 10 through the one-way light-transmitting layer 101; the first filter layer 102 is used to filter the external ambient light, and only allow part of the light to enter the display panel 10, specifically, white light and at least one of the three primary colors, that is, the light with the same wavelength as the light emitted by the organic light-emitting layer 202; the first guide layer 103 plays a role in regulating and guiding the light of the light source, that is, directing the light passing through the external ambient light to the first uniform layer 14; the second filter layer 201 is used to filter out the light except the three primary colors, that is, only allow one of the three primary colors to pass through, and then pass through the display area 200 to emit light and display the corresponding color, such as Figures 3 to 6 As shown, it usually includes three types, namely, a red filter layer 2011, a green filter layer 2012 and a blue filter layer 2013; an organic light-emitting layer 202, which is used to assist holes and electrons in generating and transmitting to the light-emitting layer for combination, excitation and emission; a reflective layer 105 is used to reflect the light after being uniformed by the first uniform layer 14 to the second guide layer 104, and then to be uniformed again by the second uniform layer 203 and then emitted through the second filter layer 201, the second guide layer 104 has the same function as the first guide layer 103, and the second uniform layer 203 has the same function as the first uniform layer 14; the second filter layer 201 has the same function as the first filter layer 102.

[0056] It should be further understood that the meaning of the second filter layer 201 having the same function as the first filter layer 102 is not only the filtering function for light, but also includes that the color and wavelength of the light allowed to pass through the second filter layer 201 are consistent with the color and wavelength of the light allowed to pass through 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 can only allow blue light to pass through; when the first filter layer 102 only allows red light to pass through, the second filter layer 201 can only allow red light to pass through; when the first filter layer 102 only allows green light to pass through, the second filter layer 201 can only allow green light to pass through.

[0057] In some embodiments, 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, and 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, and a reflective layer 105 is provided at a 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 respectively according to the three primary colors of red, green and blue, 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 advantages of this arrangement are accurate color and high brightness.

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

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

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

[0064] Among them, S B >S R >S G .

[0065] In applications, among the three primary colors, blue has the lowest brightness and green has the highest brightness. Therefore, according to the characteristics of different color luminescent materials, the area of ​​the first uniform layer 14 is set specifically. 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. The receiving area of ​​green light is the smallest, and red light is second. In this way, the final display effect can be guaranteed to have uniform color and achieve the best display effect.

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

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

[0068] In yet another embodiment, Figure 6 As shown, 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, Figure 1 and Figure 4 As shown, the first guide layer 103 is from one end close to the anode layer 13 to one end of the first uniform layer 14: at least one side of the first guide layer 103 gradually shrinks toward the middle of the first guide layer 103. This facilitates external ambient light to enter the first uniform layer 14 as quickly and as much as possible, effectively improving the brightness.

[0070] In applications, such as Figure 1 and Figure 4As shown, the first guide layer 103 is from one end close to the anode layer 13 to one end of the first uniform layer 14: one side of the first guide layer 103 gradually shrinks toward the middle of the first guide layer 103. In this way, it is convenient for the other side of the first guide layer 103 to abut against the organic light-emitting layer 202, which is convenient for manufacturing. Preferably, the first guide layer 103 is from one end close to the anode layer 13 to one end of the first uniform layer 14: both sides of the first guide layer 103 gradually shrink toward the middle of the first guide layer 103. In this way, it is beneficial to quickly guide the external ambient light to the first uniform layer 14.

[0071] In some embodiments, Figure 1 and Figure 4 As shown, the second guide layer 104 extends 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 guide layer 104 gradually increases toward the middle of the first guide layer 103 .

[0072] In applications, such as Figure 1 As shown, the second guide layer 104 is from one end close to the anode layer 13 to one end of the first uniform layer 14: one side of the second guide layer 104 gradually increases toward the middle of the second guide layer 104. In this way, it is convenient for the other side of the second guide layer 104 to abut against the organic light-emitting layer 202, which is convenient for manufacturing. Preferably, the second guide layer 104 is from one end close to the anode layer 13 to one end of the first uniform layer 14: both sides of the second guide layer 104 gradually decrease toward the middle of the second guide layer 104. In this way, it is beneficial to quickly guide the external ambient light to the first uniform layer 14.

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

[0074] In some embodiments, Figure 1 As shown, there is a gap between the first guide layer 103 and the adjacent organic light emitting layer 202 , so as to effectively avoid the light emitted by the organic light emitting layer 202 from interfering with the light in the first guide layer 103 .

[0075] In some embodiments, 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 stacked in sequence, 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 application, the sub-light-emitting layer 2023 is made of organic light-emitting materials, including at least one of blue light-emitting materials, red light-emitting materials, green light-emitting materials, and white light-emitting materials. One sub-light-emitting layer 2023 corresponds to one material. The function of the hole injection layer 2021 is to generate hole injection by current; the hole transport layer 2022 is used to assist in efficient hole transmission; the photons in the sub-light-emitting layer 2023 are combined with electrons to excite and emit light (R / G / B three colors), and different excitation materials correspond to different excitation lights; the electron transport layer 2024 assists in efficient electron transmission; the function of the electron injection layer 2025 is to generate electron injection by current; the cathode layer, the OLED panel displays current transmission and generates electrons.

[0077] In a second aspect, the present application provides a display device, such as Figure 7 As shown, it includes the above-mentioned display panel 10 and a base 20 , and the base 20 is connected to the display panel 10 .

[0078] A display device provided in an embodiment of the present application utilizes external ambient light and converts it into corresponding light emitted by an organic light-emitting material. On the one hand, the brightness of the corresponding light is improved, and on the other hand, the power consumption of the organic light-emitting material is reduced, thereby achieving the effect of increasing the lifespan.

[0079] It is particularly noteworthy that among the three organic light-emitting materials of red, green and blue, the blue light material is limited by the material itself, and the lifespan problem is particularly serious, which will appear in advance, such as brightness reduction and life reduction. Therefore, the first filter layer 102 is set in this application to allow only blue light to pass, and the organic light-emitting layer 202 in the display panel 10 is used to emit blue light, so that the brightness of the blue light in the display panel 10 can be enhanced, 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 of this application is effectively reduced, so that the service life effect can be effectively improved, thereby effectively solving the problem of brightness reduction and life reduction of the blue organic light-emitting material.
