TECHNICAL FIELD

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

[0002] Fingerprint identification technology is now very mature, with various processing methods, and optical identification and semiconductor identification technology differences. In recent years, much attention has been paid to under-screen fingerprint identification, which is more advanced and has more stringent technical requirements. Compared with occupying part of the terminal to set up a fingerprint identification area, the advantage of under-screen fingerprint identification is that it can improve the screen ratio of the terminal and the convenience in use.

[0003] However, the inventors of the present application have found that the under-screen fingerprint identification technology in the prior art usually needs to set a complex optical path system for the optical sensor so that the optical sensor can sense the reflected light of the finger. However, the setting of these complex optical path systems leads to an increase in the overall manufacturing cost of the display panel. SUMMARY

[0007] The embodiments of the present application also provide a display device comprising the display panel as described above.

[0008] Compared with the prior art, the light sensing component and the pixel unit are arranged side by side on the array substrate, the light reflected by the user's finger can directly enter the light sensing component without the obstruction of the array substrate, and therefore, the light path system for the light sensing component is not needed in the embodiment, so that the manufacturing cost is effectively reduced. In addition, the light shielding structure is arranged between the light sensing component and the pixel unit, so that the light emitted by the pixel unit cannot directly enter the light sensing component, and the collection of the light reflected by the user's finger by the light sensing component is not affected. In addition, each pixel unit has at least one adjacent pixel unit, and the light sensing components of the pixel unit and the adjacent pixel unit are arranged adjacent to each other. In the process of evaporating to form the light sensing component, the adjacent light sensing components can correspond to the same opening, so that a mask plate with a larger opening area can be used, the requirement for the alignment accuracy of the mask plate during manufacturing is effectively improved, and the influence of the deformation of the opening of the mask plate on the shape of the light sensing component is reduced.

[0009] Preferably, the pixel unit comprises an anode layer; and the light shielding structure is made of the same material as the anode layer and is located in the same layer.

The second electrode layer, the light shielding structure and the anode layer are located in the same layer, so that the light shielding structure, the anode layer and the second electrode layer can be prepared simultaneously by using the same mask plate during preparation of the display panel, the process is further simplified, and the manufacturing process is further reduced.

[0011] Preferably, the light transmittance of the light shielding structure is less than 30%. The light transmittance of the light shielding structure is less than 30%, so that the light blocking effect of the light shielding structure can be effectively guaranteed.

[0012] Preferably, the first electrode layer is made of metal, and the second electrode layer is made of transparent conductive material.

[0013] Preferably, the first electrode layer is made of molybdenum or silver. Since the conductivity of molybdenum and silver is high, the use of molybdenum or silver as the first electrode layer can effectively improve the performance of the light sensing component.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the various embodiments of this invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0027] Existing display panels with under-display fingerprint recognition have a high manufacturing cost. The inventors' research revealed that this problem arises because existing under-display fingerprint recognition technologies place the optical sensor on the back of the screen. However, due to the presence of numerous opaque components in the screen's array substrate, a significant amount of light reflected from the user's finger is blocked. Therefore, existing technologies require additional optical path systems, such as imaging pinholes or collimators, to assist the optical sensor in sensing the light reflected from the finger, thus increasing manufacturing costs.

[0028] The first embodiment of the present invention relates to a display panel, such as... Figure 1 As shown, the array includes: an array substrate 10, and a plurality of pixel units 20 disposed on the surface of the array substrate 10 and electrically connected to the array substrate 10; each pixel unit 20 includes a light-sensing component 21 arranged side by side and a plurality of sub-pixels 22 of different colors, and a light-shielding structure 30 between the light-sensing component 21 and the sub-pixels 22. The light-sensing component 21 is used to absorb light and generate current; a driving circuit is disposed within the array substrate 10 for supplying power to the sub-pixels 22 and receiving the current generated by the light-sensing component 21.

[0029] Compared with the prior art, in this application, the light-sensing component 21 and the sub-pixel 22 are arranged side by side on the surface of the array substrate 10. The light emitted by the sub-pixel 22 can be directly incident on the light-sensing component 21 after being reflected by the user's finger, without being blocked by the array substrate 10. Therefore, in this application embodiment, there is no need to set up an additional optical path system for the light-sensing component 21, thereby effectively reducing the manufacturing cost of the display panel. In addition, the light-shielding structure 30 is set between the light-sensing component 21 and the sub-pixel 22 to prevent the light emitted by the sub-pixel 22 from directly incident on the light-sensing component 21, thereby reducing the impact of stray light on the operation of the light-sensing component 21.

[0030] Specifically, in this embodiment, a sub-pixel 22 includes a green sub-pixel 221 for emitting green light, a blue sub-pixel 222 for emitting blue light, and a red sub-pixel 223 for emitting red light. The green sub-pixel 221, blue sub-pixel 222, red sub-pixel 223, and the photosensitive component 21 are arranged in a two-row, two-column matrix. Furthermore, the line connecting the green sub-pixel 221 and the photosensitive component 21 is perpendicular to the line connecting the blue sub-pixel 222 and the photosensitive component 21, and the line connecting the red sub-pixel 223 and the blue sub-pixel 222 is perpendicular to the line connecting the red sub-pixel 223 and the green sub-pixel 221. It should be understood that the above is merely an example of pixel positions in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the positions of the green sub-pixel 221, blue sub-pixel 222, and red sub-pixel 223 can also be interchanged, and can be flexibly set according to actual needs. It is understood that the above is only a specific example in this embodiment and does not constitute a limitation. In other embodiments of the present invention, a pixel unit 20 may also include other numbers of sub-pixels 22, which can be flexibly set according to actual needs.

[0031] Furthermore, in this application, adjacent light-shielding structures 30 are interconnected. This interconnection prevents light emitted from the diagonally opposite sub-pixels 22 of the light-sensing component 21 from directly entering the light-sensing component 21. It is understood that the interconnection of adjacent light-shielding structures 30 is merely a specific example in this application and does not constitute a limitation. In other embodiments of the present invention, the adjacent light-shielding structures can also be in other forms, such as adjacent light-shielding structures being independently arranged and enclosing the diagonal position of the light-sensing component 21. Specific arrangements can be flexibly made according to actual needs, and will not be listed here. Specifically, for example... Figure 2 As shown, the photosensitive component 21 includes a first electrode layer 211 electrically connected to the array substrate 10, a light-absorbing layer 212 disposed on the surface of the first electrode layer 211, and a second electrode layer 213 disposed on the surface of the light-absorbing layer 212. The light-absorbing layer 212 is essentially a PN junction. The light-absorbing layer 212, the first electrode layer 211, and the second electrode layer 213 together form a photodiode, thereby generating current under illumination.

[0032] More preferably, in other embodiments of the present invention, the light-shielding structure 30 may be arranged around the light-sensing component 21. The light-shielding structure 30, arranged around the light-sensing component 21, can block stray light directly entering the light-sensing component 21 from all angles, achieving a better light-blocking effect.

[0033] Furthermore, in this embodiment, the light transmittance of the light-shielding structure 30 is less than 30%. The light transmittance of the light-shielding structure 30 is less than 30%, thus ensuring its light-shielding effect. It is understood that the light transmittance of the light-shielding structure 30 being less than 30% is only a preferred embodiment proposed in this invention. In other embodiments of the present invention, the light transmittance of the light-shielding structure 30 may also be greater than or equal to 30%. As long as the light transmittance of the light-shielding structure 30 is not equal to 100%, it can still serve the purpose of light shielding and can all be used as the light-shielding structure in this application; further details will not be elaborated here.

[0034] Furthermore, the array substrate 10 includes an upper side plate 11 that is attached to the photosensitive component 21, and a substrate electrode 12 that penetrates the upper side plate 11 and is electrically connected to the first electrode layer 211. The first electrode layer 211 is electrically connected to the substrate electrode 12, thereby making the photosensitive component 21 electrically connected to the array substrate 10.

[0035] Specifically, in this embodiment, the first electrode layer 211 is made of metal. It is understood that the use of metal for the first electrode layer 211 is merely a specific example in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the first electrode layer 211 may also be made of other conductive materials, such as ITO, etc., which will not be listed here. The appropriate material can be flexibly selected according to actual needs.

[0036] Preferably, in this embodiment, the first electrode layer 211 is made of molybdenum or silver. Since molybdenum and silver have high conductivity, using molybdenum or silver as the first electrode layer 211 can effectively improve the performance of the photosensitive component 21. It is understood that the use of molybdenum or silver as the material of the first electrode layer 211 is merely a specific example in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the first electrode layer 211 can also be other metallic materials, such as aluminum, etc., which will not be listed here.

[0037] Specifically, the second electrode layer 213 is made of a transparent conductive material, such as ITO and IZO.

[0038] Furthermore, in this embodiment, the thickness of the light absorption layer 212 is less than or equal to 1 micrometer. When the thickness of the light absorption layer 212 is less than 1 micrometer, it can selectively absorb some colored light. When the thickness of the light absorption layer 212 is equal to 1 micrometer, the light absorption layer 212 can absorb colored light of all wavelengths, achieving the maximum light absorption rate and the maximum working efficiency.

[0039] Furthermore, in this embodiment, the light-shielding structure 30 is partially disposed on the array substrate 10, and the thickness of the light-shielding structure 30 is greater than the thickness of the photosensitive component 21. The greater thickness of the light-shielding structure 30 than the thickness of the photosensitive component 21 can prevent the light emitted by the sub-pixel 22 from directly incident on the photosensitive component 21 from above the light-shielding structure 30, thus better preventing the light emitted by the sub-pixel 22 from directly entering the photosensitive component 21.

[0040] Specifically, in this embodiment, an insulating layer 40 covering the array substrate 10 is also included. The insulating layer 40 covers the first electrode layer 211 and the light absorption layer 212, and a first through-hole 41 penetrating the insulating layer 40 is provided above the light absorption layer 212. The second electrode layer 213 is disposed on the light absorption layer 212 through the first through-hole 41. The insulating layer 40 covering the first electrode layer 211 and the light absorption layer 212, and the second electrode layer 213 being disposed on the light absorption layer 212 through the first through-hole 41, can prevent the second electrode layer 213 from directly contacting the first electrode layer 211, thus preventing abnormal operation of the photosensitive component 21.

[0041] Furthermore, in this embodiment, the insulating layer 40 further includes a second through-hole 42 and a third through-hole 43 penetrating the insulating layer 40; wherein, the second through-hole 42 is disposed in the region where the light-shielding structure 30 is located, and the third through-hole 43 is disposed in the region where the sub-pixel 22 is located. The light-shielding component 23 is disposed on the surface of the insulating layer 40 and disposed on the array substrate 10 via the second through-hole 42. Thus, a specific structure is provided to realize the feature that the thickness of the light-shielding structure 30 is greater than the thickness of the photosensitive component 21.

[0042] In addition, in this embodiment, the insulating layer 40 can be made of either a transparent material, such as silicon dioxide, or an opaque material, such as silicon nitride. When the insulating layer 40 is made of an opaque material, it can also achieve a certain light-blocking effect, thus better preventing the light emitted by the sub-pixel 22 from directly incident on the light-sensing component 21.

[0043] Furthermore, in this application, the light-emitting pixel 22 includes an anode layer 224, an organic light-emitting layer 225, a cathode layer 226, and a pixel defining layer 227. The light-shielding structure 30 is made of the same material as the anode layer 224 and is located in the same layer. Because the light-shielding structure 30 and the anode layer 224 are made of the same material and are located in the same layer, the same mask can be used to simultaneously fabricate the light-shielding structure 30 and the anode layer 224 when manufacturing the display panel, reducing the manufacturing process and simplifying the fabrication process.

[0044] More preferably, in this embodiment, the second electrode layer 213, the light-shielding structure 30, and the anode layer 224 are located on the same layer. When fabricating the display panel, the light-shielding structure 30, the anode layer 224, and the second electrode layer 213 can be fabricated simultaneously using the same mask, further simplifying the manufacturing process. For example, the light-shielding structure 30 and the anode layer 224 are both made of two layers of ITO sandwiched with a layer of silver, and the second electrode layer 213 is also made of ITO. When depositing any one layer of ITO in the light-shielding structure 30 or the anode layer 224, the second electrode 213 can be deposited simultaneously, effectively simplifying the manufacturing process.

[0045] Specifically, in this embodiment, the anode layer 224 is not connected to the light-shielding structure 30, and the second electrode layer 213 is electrically connected to the light-shielding structure 30.

[0046] Furthermore, in this embodiment, a planarization layer 50 covering the pixel unit 20 and a light-concentrating component 60 disposed on the surface of the planarization layer 50 are also included; the light-concentrating component 60 is disposed opposite to the light-sensing component 21. By disposing the light-concentrating component 60 on the surface of the planarization layer 50, the light reflected from the finger can be focused towards the light-sensing component 21, thereby increasing the light intensity reflected to the light-sensing component 21 and effectively improving the accuracy of fingerprint recognition.

[0047] Specifically, in this embodiment, the light-concentrating component 60 is a convex lens.

[0048] The second embodiment of the present invention relates to a display panel. This embodiment is a further improvement on the first embodiment, and includes all the technical features of the first embodiment, such as... Figure 3 As shown, each pixel unit 20 includes at least one adjacent pixel unit, and the pixel unit 20 is adjacent to the light-sensing component 21 contained in the adjacent pixel unit.

[0049] Compared with the prior art, the display panel provided in this embodiment retains all the technical effects of the first embodiment while providing at least one adjacent pixel unit for each pixel unit 20, and the adjacent pixel units and the two photosensitive components 21 contained in the pixel unit 20 are arranged adjacently. During the fabrication of the photosensitive components 21, adjacent photosensitive components 21 can share the same opening, thereby using a mask with a larger opening area, effectively improving the alignment accuracy requirements of the mask during fabrication, and reducing the influence of mask opening deformation on the shape of the photosensitive components 21.

[0050] Preferably, in this embodiment, a pixel unit 20 is composed of a light-sensing component 21 and three different types of sub-pixels 22 arranged in a matrix of two rows and two columns.

[0051] More preferably, every two adjacent pixel units 20 are arranged symmetrically. Since a pixel unit 20 consists of a photosensitive component 21 and three different types of sub-pixels 22 arranged in a two-row, two-column matrix; and since every two adjacent pixel units 20 are symmetrically arranged, every two adjacent pixel units 20 necessarily include two sub-pixels 22 of the same type arranged adjacently. During the fabrication of the sub-pixels 22, adjacent sub-pixels 22 can share the same opening, thus allowing the use of a mask with a larger opening area. This effectively improves the alignment accuracy requirements of the mask during fabrication and reduces the impact of mask opening deformation on the shape of the sub-pixels 22.

[0052] Specifically, in this embodiment, the three different types of sub-pixels 22 include a green sub-pixel 221 for emitting green light, a blue sub-pixel 222 for emitting blue light, and a red sub-pixel 223 for emitting red light. The green sub-pixel 221, blue sub-pixel 222, red sub-pixel 223, and the light-sensing component 21 are located at the four corners of the grid. Furthermore, the line connecting the green sub-pixel 221 and the light-sensing component 21 is perpendicular to the line connecting the blue sub-pixel 222 and the light-sensing component 21, and the line connecting the red sub-pixel 223 and the blue sub-pixel 222 is perpendicular to the line connecting the red sub-pixel 223 and the green sub-pixel 221. It should be understood that the above is merely an example of pixel positions in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the positions of the green sub-pixel 221, blue sub-pixel 222, and red sub-pixel 223 can also be interchanged, and can be flexibly set according to actual needs.

[0053] Preferred, such as Figure 4 As shown, in this embodiment, adjacent photosensitive components 21 are interconnected to form a whole. This interconnection eliminates the gaps between adjacent photosensitive components 21, increases the photosensitive area, and thus improves the photosensitive effect and fingerprint recognition accuracy.

[0054] The third embodiment of the present invention relates to a display panel, such as Figure 5 As shown, the array includes an array substrate 10 and a plurality of pixel units 20 electrically connected to the array substrate 10; each pixel unit 20 includes a light-sensing component 21 and a sub-pixel 22 arranged side by side on the surface of the array substrate 10; each pixel unit 20 has at least one adjacent pixel unit, and the pixel unit 20 is arranged adjacent to the light-sensing component 21 contained in the adjacent pixel unit.

[0055] Compared with the prior art, the display panel provided in this embodiment retains all the technical effects of the first embodiment while providing at least one adjacent pixel unit for each pixel unit 20, and the adjacent pixel units and the two photosensitive components 21 contained in the pixel unit 20 are arranged adjacently. During the fabrication of the photosensitive components 21, adjacent photosensitive components 21 can share the same opening, thereby using a mask with a larger opening area, effectively improving the alignment accuracy requirements of the mask during fabrication, and reducing the influence of mask opening deformation on the shape of the photosensitive components 21.

[0056] Preferably, in this embodiment, a pixel unit 20 is composed of a light-sensing component 21 and three different types of sub-pixels 22 arranged in a matrix of two rows and two columns.

[0057] More preferably, every two adjacent pixel units 20 are arranged symmetrically. Since a pixel unit 20 consists of a photosensitive component 21 and three different types of sub-pixels 22 arranged in a two-row, two-column matrix; and since every two adjacent pixel units 20 are symmetrically arranged, every two adjacent pixel units 20 necessarily include two sub-pixels 22 of the same type arranged adjacently. During the fabrication of the sub-pixels 22, adjacent sub-pixels 22 can share the same opening, thus allowing the use of a mask with a larger opening area. This effectively improves the alignment accuracy requirements of the mask during fabrication and reduces the impact of mask opening deformation on the shape of the sub-pixels 22.

[0058] Specifically, in this embodiment, the three different types of sub-pixels 22 include a green sub-pixel 221 for emitting green light, a blue sub-pixel 222 for emitting blue light, and a red sub-pixel 223 for emitting red light. The green sub-pixel 221, blue sub-pixel 222, red sub-pixel 223, and the light-sensing component 21 are located at the four corners of the grid. Furthermore, the line connecting the green sub-pixel 221 and the light-sensing component 21 is perpendicular to the line connecting the blue sub-pixel 222 and the light-sensing component 21, and the line connecting the red sub-pixel 223 and the blue sub-pixel 222 is perpendicular to the line connecting the red sub-pixel 223 and the green sub-pixel 221. It should be understood that the above is merely an example of pixel positions in this embodiment and does not constitute a limitation. In other embodiments of the present invention, the positions of the green sub-pixel 221, blue sub-pixel 222, and red sub-pixel 223 can also be interchanged, and can be flexibly set according to actual needs.

[0059] Preferred, such as Figure 6As shown, in this embodiment, adjacent photosensitive components 21 are interconnected to form a whole. This interconnection eliminates the gaps between adjacent photosensitive components 21, increases the photosensitive area, and thus improves the photosensitive effect and fingerprint recognition accuracy.

[0060] The fourth embodiment of the present invention relates to a display device, including the display panel provided in any of the above embodiments.

[0061] Compared with the prior art, the display device provided in the fourth embodiment of the present invention includes the display panel as provided in any of the embodiments described above, and therefore has the same technical effects.

[0062] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of the present invention.
