Description

Technical Field

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

[0002] In recent years, conventional inorganic semiconductor light-emitting diodes, such as Micro-LED, have become a hot technology in the display market. Compared with the display technologies that have been mass-produced, such as LCD and OLED, they have better performance in technical dimensions such as brightness, color, viewing angle, contrast, resolution and life.

[0003] However, full-color Micro-LED currently requires the transfer of R / G / B three-color LEDs, which requires a large number of transfers, is difficult, and has high costs, limiting the promotion and application of Micro-LEDs. In addition, due to the differences in the light efficiency of the R / G / B three-color LED light-emitting chips, the light efficiency of the R / G / B three-color LED light-emitting chips is uneven, which in turn causes the display device to have poor brightness uniformity, affecting the mixed color display effect. Therefore, it is urgent to invent a display device that can ensure display brightness uniformity and has a good mixed color display effect. Summary of the invention

[0004] In view of this, an embodiment of the present invention provides a display panel and a display device, which have better brightness uniformity and better mixed color display effect.

[0005] In a first aspect, the present application provides a display panel, comprising:

[0006] display area and non-display area, the display area comprising a first display area and a second display area, the second display area at least partially surrounds the first display area, and the second display area is adjacent to the non-display area;

[0007] Driver substrate;

[0008] A light emitting element, the light emitting element is located on one side of the driving substrate, and the light emitting element includes an organic light emitting element and an inorganic light emitting element;

[0009] The first display area includes the organic light emitting element and the inorganic light emitting element, and the second display area only includes the inorganic light emitting element.

[0010] In a second aspect, the present application provides a display device, which includes the display panel.

[0011] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0012] The present application provides a display panel and a display device, wherein the display panel includes a first display area and a second display area, wherein the second display area at least partially surrounds the first display area, and the second display area is adjacent to a non-display area, wherein the first display area includes an organic light-emitting element and an inorganic light-emitting element, and the second display area includes only an inorganic light-emitting element. On the one hand, because light-emitting elements of different material types have different external quantum efficiencies at light-emitting wavelengths, and light-emitting elements of different colors have different external quantum efficiencies in different material types, the first display area can improve the overall luminous efficiency, enhance the display effect, and reduce power consumption by using a mixture of organic and inorganic light-emitting elements; On the other hand, the edge of the display panel is more susceptible to corrosion by water vapor. The second display area is closer to the non-display area of ​​the display panel than the first display area, that is, the second display area is close to the outer edge of the display panel, and is also more susceptible to corrosion by water vapor. Compared with inorganic light-emitting elements, organic light-emitting elements have lower tolerance to water vapor due to their own material properties. Therefore, only inorganic light-emitting elements are arranged in the second display area, which can ensure the reliability of the display panel. In addition, the second display area is adjacent to the non-display area, and the display effect requirement is lower than that of the central area of ​​the display area, which will not have a significant impact on the display. Therefore, the present invention can make the display panel have a higher display effect and better reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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 of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Inorganic semiconductor light-emitting diodes, such as Micro-LED, have become a hot technology in the display market. Compared with the display technologies that have been mass-produced, such as LCD and OLED, they have more excellent performance in technical dimensions such as brightness, color, viewing angle, contrast, resolution and life.

[0026] However, full-color Micro-LED currently requires the transfer of R / G / B three-color LEDs, which requires a large number of transfers, is difficult and costly, limiting the promotion and application of Micro-LEDs. In addition, due to the differences in the light efficiency of the R / G / B three-color LED chips, the light efficiency of the R / G / B three-color LED chips is uneven, which in turn causes the display device to have poor brightness uniformity, affecting the mixed color display effect. Figure 1 , Figure 1 This is a comparison chart of the external quantum efficiency of organic light-emitting elements and inorganic light-emitting elements. Figure 1The external quantum efficiency (EQE) of RGB three-color organic light-emitting elements and inorganic light-emitting elements is shown in the figure, where R is red, G is green, and B is blue. At a specific emission wavelength, among the inorganic light-emitting elements with a size of 15μm, the external quantum efficiency of green and blue inorganic light-emitting elements are 30% and 40%, respectively, which are higher than the external quantum efficiency of green and blue organic light-emitting elements, which are 22% and 7%, respectively. In particular, the blue inorganic light-emitting element, which is usually a blue light Micro-LED based on GaN (gallium nitride) material, has an obvious advantage in brightness. However, the red inorganic light-emitting element, which is usually a red light Micro-LED based on AlGaInP (aluminum gallium indium phosphide) material, has an external quantum efficiency of only 10% due to differences in materials and preparation processes, which is much lower than that of the blue inorganic light-emitting element and the red organic light-emitting element. Therefore, when preparing a display panel with full-color inorganic light-emitting elements, the brightness of the RGB three-color inorganic light-emitting elements may not match, and the brightness of the red inorganic light-emitting element is low, resulting in distortion of the color display after color mixing, poor display effect of the display panel, and high power consumption.

[0027] Based on the existing problems, the inventor of the present invention proposes a display panel and a display device, which have good brightness uniformity and good mixed color display effect. Figure 2 As shown, Figure 2 A top view schematic diagram of a display panel provided in an embodiment of the present invention; A display panel 1 provided in an embodiment of the present invention comprises a display area 10 and a non-display area 20, wherein the display area 10 comprises a first display area 11 and a second display area 12, the second display area 12 at least partially surrounds the first display area 11, and the second display area 12 is adjacent to the non-display area 20; the display panel 1 comprises a driving substrate A, and a light-emitting element P located on one side of the driving substrate A, wherein the light-emitting element P located in the first display area 11 comprises an organic light-emitting element P1 and an inorganic light-emitting element P2, and the light-emitting element P located in the second display area 12 comprises only an inorganic light-emitting element P2.

[0028] On the one hand, because light-emitting elements P of different material types have different external quantum efficiencies at the emission wavelength, and light-emitting elements of different colors have different external quantum efficiencies in different material types, such as Figure 1The external quantum efficiency of the red organic light-emitting element is 22%, while the external quantum efficiency of the red inorganic light-emitting element is 10%. The first display area 11 can improve the overall luminous efficiency, enhance the display effect, and reduce power consumption by using a mixture of organic and inorganic light-emitting elements. On the other hand, the edge of the display panel 1 is more susceptible to erosion by water vapor. The second display area 12 is closer to the non-display area 20 of the display panel 1 than the first display area 11. Therefore, the second display area 12 is also close to the outer edge of the display panel 1 and is also more susceptible to erosion by water vapor. Compared with the inorganic light-emitting element P2, the organic light-emitting element P1 has a lower tolerance to water vapor due to its own material characteristics. Therefore, only the inorganic light-emitting element P2 is arranged in the second display area 12, which can effectively ensure the reliability of the display panel 1. The second display area 12 is close to the non-display area 20, and the display effect requirement is lower than that of the central area of ​​the display area 10, which will not have a significant impact on the display. Therefore, the present invention can make the display panel 1 have a higher display effect and better reliability.

[0029] It should be noted that Figure 2 Only a rectangular display panel is shown in the figure. In other embodiments provided by the present invention, the shape of the display panel can be any shape, and the first display area 11 and the second display area 12 both include a plurality of light-emitting elements P. The specific range of the second display area 12 can be determined according to the overall packaging effect of the display panel and the specific size of the display area. The present invention does not limit the specific range of the second display area 12. Optionally, the second display area 12 includes at least a distance of a light-emitting unit W, wherein one light-emitting unit W may include a red light-emitting element, a green light-emitting element, and a blue light-emitting element.

[0030] Optional, such as Figure 3 As shown, Figure 3A schematic top view of another display panel provided for an embodiment of the present invention; a first display area 11 includes a plurality of light-emitting units W, the light-emitting unit W includes at least one light-emitting element P, the light-emitting elements P in one light-emitting unit W are all organic light-emitting elements P1, or the light-emitting elements P in one light-emitting unit W are all inorganic light-emitting elements P2, wherein the light-emitting unit W having the organic light-emitting element P1 is a first type of light-emitting unit W1, and the light-emitting unit W having the inorganic light-emitting element P2 is a second type of light-emitting unit W2, and along the first direction X and / or the second direction Y, the first type of light-emitting unit W1 and the second type of light-emitting unit W2 are adjacently arranged, and the first direction X and the second direction Y intersect. Since there are certain differences in the excitation wavelengths of the organic light-emitting element P1 and the inorganic light-emitting element P2, the brightness and chromaticity of their displays are also different. In the first direction X and / or the second direction Y, by arranging the first type of light-emitting unit W1 and the second type of light-emitting unit W2 adjacent to each other, it is possible to avoid differences in color blocks in local areas on the display panel 1, and to avoid uneven brightness and chromaticity. That is, in the first direction X and / or the second direction Y, by arranging the first type of light-emitting unit W1 and the second type of light-emitting unit W2 adjacent to each other, the mixing effect of the two is better, which helps to ensure the uniformity of the display of the display panel.

[0031] Optional, such as Figure 4-5 As shown, Figure 4 A schematic top view of another display panel provided by an embodiment of the present invention, Figure 5A top view schematic diagram of another display panel provided for an embodiment of the present invention; the light-emitting element P includes a first color light-emitting element P01, a second color light-emitting element P02 and a third color light-emitting element P03, such as a red light-emitting element, a green light-emitting element, and a blue light-emitting element; at least one color light-emitting element can be set as the first light-emitting element K1, and the rest are second light-emitting elements K2, wherein the first light-emitting element K1 includes an organic light-emitting element P1 and an inorganic light-emitting element P2, and the second light-emitting element K2 only includes the inorganic light-emitting element P2. On the one hand, for light-emitting elements of different materials and the same color, there is a situation where either the organic light-emitting element P1 has a higher luminous efficiency or the inorganic light-emitting element P2 has a higher luminous efficiency. At least one of the color light-emitting elements is provided to include the organic light-emitting element P1 and the inorganic light-emitting element P2, that is, a light-emitting element of a certain color in which the organic light-emitting element P1 has a higher luminous efficiency than the inorganic light-emitting element P2 can be provided. When the organic light-emitting element P1 and the inorganic light-emitting element P2 are provided at the same time, the overall luminous efficiency of the light-emitting element of this color can be improved, the driving power consumption of the light-emitting element of this color can be reduced, and the advantages of the inorganic light-emitting element P2 of other colors can be maintained. On the other hand, since the preparation methods of the organic light-emitting element P1 and the inorganic light-emitting element P2 are inconsistent, the organic light-emitting element P1 is usually prepared directly on the driving substrate A, while the inorganic light-emitting element P2 needs to complete epitaxial growth and preparation on other substrates in advance, and then be transferred from other substrates to the driving substrate A. The provision of at least one of the color light-emitting elements to include the organic light-emitting element P1 and the inorganic light-emitting element P2 can also minimize the preparation differences and save costs.

[0032] Optional, such as Figure 4 As shown, the first light emitting element K1 may only include the first color light emitting element P01, wherein the first color light emitting element P01 is a red light emitting element. Figure 1 In the red light-emitting element, the external quantum efficiency of the red organic light-emitting element is 22%, and the external quantum efficiency of the red inorganic light-emitting element is 10%. The first light-emitting element K1 is set to include only the red light-emitting element, that is, the red light-emitting element includes the organic light-emitting element P1 and the inorganic light-emitting element P2, while the green and blue light-emitting elements include only the inorganic light-emitting element P2. On the one hand, the overall luminous efficiency of the red light-emitting element can be improved, and the driving power consumption of the red light-emitting element can be reduced, while maintaining the advantages of the green and blue inorganic light-emitting elements themselves; on the other hand, only the organic light-emitting element P1 and the inorganic light-emitting element P2 are prepared for the red light-emitting element, which reduces the difficulty of preparation and saves costs.

[0033] Optional, such as Figure 5 As shown, the first light emitting element K1 may include a first color light emitting element P01 and a third color light emitting element P03, wherein the first color light emitting element P01 is a red light emitting element, and the third color light emitting element P03 is a blue light emitting element. Figure 1 Among the blue light-emitting elements, the external quantum efficiency of the blue organic light-emitting element is 7%, while the external quantum efficiency of the blue inorganic light-emitting element reaches 40%; among the green light-emitting elements, the external quantum efficiency of the green organic light-emitting element is 22%, and the external quantum efficiency of the green inorganic light-emitting element is 30%; therefore, among the light-emitting elements of different colors, the luminous efficiencies of the red organic light-emitting element and the red inorganic light-emitting element, and the blue organic light-emitting element and the blue inorganic light-emitting element are quite different, while the luminous efficiency difference between the green organic light-emitting element and the green inorganic light-emitting element is relatively small. At this time, the red light-emitting element and the blue light-emitting element are both provided to include the organic light-emitting element P1 and the inorganic light-emitting element P2, which can further balance the brightness of RGB and avoid the problem of excessive brightness difference between R and B, resulting in poor color mixing.

[0034] Optionally, in light-emitting elements of different colors, the specific proportional relationship between the organic light-emitting element P1 and the inorganic light-emitting element P2 can be adjusted according to different chromaticity requirements, light-emitting element materials and sizes. That is to say, if the ratio between the organic light-emitting element P1 and the inorganic light-emitting element P2 in the first color light-emitting element P01 is m1:m2, the ratio between the organic light-emitting element P1 and the inorganic light-emitting element P2 in the second color light-emitting element P02 is m3:m4, and the ratio between the organic light-emitting element P1 and the inorganic light-emitting element P2 in the third color light-emitting element P03 is m5:m6, then m1 to m6 can be set according to requirements, and the present invention is not limited to this.

[0035] Optional, such as Figure 6 As shown, Figure 6A top view schematic diagram of another display panel provided in an embodiment of the present invention; at least one color light-emitting element can be set as a third light-emitting element K3, and the rest are fourth light-emitting elements K4, wherein the third light-emitting element K3 only includes the organic light-emitting element P1, and the fourth light-emitting element K4 only includes the inorganic light-emitting element P2. On the one hand, for light-emitting elements of different materials and the same color, there is a situation where either the organic light-emitting element P1 has a higher luminous efficiency or the inorganic light-emitting element P2 has a higher luminous efficiency. At least one of the color light-emitting elements is set to include only the organic light-emitting element P1, and the other color light-emitting elements are set to include only the inorganic light-emitting element P2. The advantages of the organic light-emitting element P1 and the inorganic light-emitting element P2 with higher luminous efficiency in the light-emitting elements of different colors can be utilized respectively, so that the overall luminous efficiency of the display panel 1 is effectively improved, and the driving power consumption of the display panel 1 is greatly reduced; on the other hand, since the preparation methods of the organic light-emitting element P1 and the inorganic light-emitting element P2 are inconsistent, the organic light-emitting element P1 is usually directly prepared on the driving substrate A, while the inorganic light-emitting element P2 needs to complete epitaxial growth and preparation on other substrates in advance, and then transferred from the other substrates to the driving substrate A. At least one of the color light-emitting elements is set to include only the organic light-emitting element P1, and the other color light-emitting elements are set to include only the inorganic light-emitting element P2, which greatly reduces the preparation differences and saves costs.

[0036] Optional, such as Figure 6 As shown, the third light emitting element K3 may only include the first color light emitting element P01, wherein the first color light emitting element P01 is a red light emitting element. Figure 1 In the red light-emitting element, the external quantum efficiency of the red organic light-emitting element is greater than the external quantum efficiency of the red inorganic light-emitting element; while in the green light-emitting element, the external quantum efficiency of the green organic light-emitting element is less than the external quantum efficiency of the green inorganic light-emitting element; in the blue light-emitting element, the external quantum efficiency of the blue organic light-emitting element is less than the external quantum efficiency of the blue inorganic light-emitting element; therefore, the red light-emitting elements can be set to be organic light-emitting elements P1, and the green and blue light-emitting elements can be set to be inorganic light-emitting elements P2. On the one hand, the advantages of the luminous efficiency of different types of red, green and blue light-emitting elements can be fully utilized to ensure that the display panel 1 has a higher brightness and lower driving power consumption; on the other hand, the red organic light-emitting element can be first prepared on the driving substrate A, and then the green and blue inorganic light-emitting elements can be transferred to the driving substrate A. The preparation method is simple and easy, and cost-saving.

[0037] Optional, such as Figure 7-Figure 8 As shown, Figure 7 A schematic top view of another display panel provided by an embodiment of the present invention is shown. Figure 8 A schematic top view of another display panel provided by an embodiment of the present invention; the display panel 1 includes a main light emitting element M1 and a backup light emitting element M2, Figure 7 and Figure 8 The main light emitting element M1 is displayed in a dark color, and the backup light emitting element M2 is displayed in a light color. When the main light emitting element M1 fails or is damaged, the backup light emitting element M2 can replace the main light emitting element M1 that fails or is damaged. Figure 7 In the embodiment, the main light-emitting element M1 and the backup light-emitting element M2 may both include an organic light-emitting element P1 and an inorganic light-emitting element P2. Furthermore, the main light-emitting element M1 and the backup light-emitting element M2 may both include an equal proportion of an organic light-emitting element P1 and an inorganic light-emitting element P2, and the main light-emitting element M1 and the backup light-emitting element M2 at corresponding positions are light-emitting elements of the same type, so that when the main light-emitting element M1 fails or is damaged, the backup light-emitting element M2 can be replaced in an equal manner, that is, the brightness and chromaticity of the backup light-emitting element M2 and the corresponding main light-emitting element M1 are substantially consistent, thereby ensuring the normal display of the display panel 1.

[0038] Optional, such as Figure 8 As shown, the main light-emitting element M1 may also be set to include an organic light-emitting element P1 and an inorganic light-emitting element P2, and the backup light-emitting element M2 may only include an inorganic light-emitting element P2. Since the display panel 1 mainly uses the main light-emitting element M1 for image display, the backup light-emitting element M2 is relatively less used than the main light-emitting element M1, and is only enabled when the main light-emitting element M1 fails or is damaged, and the inorganic light-emitting element P2 has a longer service life and better reliability than the organic light-emitting element P1. Therefore, only the main light-emitting element M1 is set to include an organic light-emitting element P1 and an inorganic light-emitting element P2, and the backup light-emitting element M2 is set to be an inorganic light-emitting element P2, thereby ensuring that the display panel 1 has a good display effect, and at the same time, it can also ensure that the backup light-emitting element M2 can effectively replace the main light-emitting element M1, thereby improving the reliability of the display panel 1. At the same time, the backup light-emitting element M2 does not need to adopt two preparation methods to prepare the light-emitting element, further reducing the preparation cost.

[0039] Optional, such as Fig. 9 As shown, Fig. 9A top view schematic diagram of another display panel provided for an embodiment of the present invention; the first display area 11 includes a first sub-display area 111 and a second sub-display area 112, the second sub-display area 112 is located between the first sub-display area 111 and the second display area 12, optionally, the second sub-display area 112 at least partially surrounds the first sub-display area 111, the number of organic light-emitting elements P1 and inorganic light-emitting elements P2 included in the first sub-display area 111 is n1:n2, the number of organic light-emitting elements P1 and inorganic light-emitting elements P2 included in the second sub-display area 112 is n3:n4, and n1:n2 can be set to be greater than n3:n4. Since the second sub-display area 112 is located between the first sub-display area 111 and the second display area 12, that is, the first sub-display area 111 passes through the second sub-display area 112 to the second display area 12, and the second display area 12 is only provided with an inorganic light-emitting element P2, and no organic light-emitting element P1 is provided, the first display area 11 is provided with an organic light-emitting element P1 and an inorganic light-emitting element P2, and because there are differences in brightness and chromaticity between the organic light-emitting element P1 and the inorganic light-emitting element P2 due to factors such as materials, that is, there are also certain differences in brightness and chromaticity between the second display area 12 and the first display area 11; optionally, different voltage settings can be adopted to compensate for the difference in display effects between the second display area 12 and the first display area 11, such as using different driving voltages for the inorganic light-emitting elements P2 of the same color in the two areas to compensate for The luminous brightness of the light-emitting elements of the same color in different areas; optionally, different proportions of driving voltages can be selected for the light-emitting elements of different colors in the first display area 11 and the second display area 12 to compensate for the chromaticity difference between the first display area 11 and the second display area 12; optionally, a transition area can be set, such as a second sub-display area 112, in which the proportion of the organic light-emitting element P1 decreases, and further, the proportion of the organic light-emitting element P1 in the second sub-display area 112 can be set to gradually decrease, that is, the closer to the second display area 12, the lower the number of organic light-emitting elements P1, thereby ensuring that the display brightness and chromaticity can change gradually in the direction from the first sub-display area 111 to the second display area 12, avoiding sudden changes in brightness and chromaticity, thereby ensuring that the display panel 1 has a better display effect.

[0040] It should be noted that if Figure 2 to Figure 9 The present invention only exemplarily shows one arrangement of the light-emitting elements P. Optionally, in other embodiments of the present invention, the arrangement of the light-emitting elements P can be arbitrarily selected, and the number of light-emitting elements P shown in the figure does not represent the specific number of light-emitting elements P included in the display panel. This part can be adjusted and set according to needs, and the present invention does not limit it.
