[0001] The present application belongs to the technical field of electronic products, and specifically relates to a display screen and an electronic device. Background Art

[0002] With the continuous development of display screens, users have higher and higher requirements on the picture quality of display screens, that is, they hope that the picture quality of display screens will be more delicate and realistic.

[0003] In order to improve the display effect of the display screen, taking the OLED (Organic Light Emitting Diode) display screen as an example, the methods commonly used in related technologies include increasing the RGB value, increasing the contrast and reducing the brightness, among which increasing the RGB value refers to increasing the brightness values ​​of the three luminous pixels of red, green and blue; taking the LCD display screen as an example, the methods commonly used in related technologies include increasing the contrast and reducing the brightness, etc. Although the above methods can improve the display effect of the display screen to a certain extent, the improvement is limited. Therefore, this still cannot meet the user's demand for picture quality.

[0004] In summary, the display screen involved in the related art has the problem of poor display effect. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a display screen and an electronic device that can solve the problem of poor display effect of the display screen involved in the related art.

[0007] An embodiment of the present application provides an electronic device, comprising a housing and the display screen described above, wherein the display screen is connected to the housing.

[0008] In the embodiment of the present application, since each pixel area faces each concave lens in a one-to-one correspondence, each concave lens can expand the irradiation area of ​​the light emitted by each pixel area. Therefore, even if the size of each pixel area is reduced in the present application, the overall display effect of the display screen is not affected. It can be seen that the present application can reduce the size of each pixel area, that is, by reducing the size of each pixel area, the area occupied by each pixel area is reduced, and the number of pixel areas per unit area can be increased, which makes the image quality of the display screen more delicate and realistic, that is, this setting method can better improve the display effect of the display screen.

DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0013] The display screen disclosed in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-Figure 2 The present application discloses a display screen, which includes a display layer 100 and a first lens layer 200 .

[0015] The display screen has a display function, and the display layer 100 is used to display the picture. The first lens layer 200 is light-transmissive, and the display layer 100 and the first lens layer 200 are sequentially stacked in the thickness direction of the display screen. The display layer 100 may specifically include a plurality of pixel regions 110 arranged in an array, and different pixel regions 110 may emit red, green, and blue light.

[0016] The display screen disclosed in the present application may be a liquid crystal display screen or an OLED (Organic Light Emitting Diode) display screen. Taking the liquid crystal display screen as an example, the display layer 100 may include a color filter film, the pixel area 110 may be a filter block included in the color filter film, and the light emitted by the backlight source may be emitted through the pixel area 110.

[0017] Please refer to Figure 1 Taking the OLED display screen as an example, the pixel area 110 can be a self-luminous pixel included in the display layer 100, that is, the display layer 100 can be an organic light-emitting layer. At this time, the display layer 100 can also include a pixel spacer 120, which is arranged between adjacent pixel areas 110 to separate adjacent pixel areas 110, thereby preventing the occurrence of cross-color phenomenon between adjacent pixel areas 110.

[0018] The first lens layer 200 may include a plurality of concave lenses 210 arranged in an array, and each pixel area 110 faces each concave lens 210 one by one, that is, the light emitted from each pixel area 110 can pass through the corresponding concave lens 210. Since the concave lens 210 has the function of diffusing light, the light emitted from each pixel area 110 can expand the coverage area of ​​the light after passing through the corresponding concave lens 210.

[0019] In the embodiment of the present application, since each pixel area 110 faces each concave lens 210 in a one-to-one correspondence, each concave lens 210 can expand the irradiation area of ​​the light emitted by each pixel area 110. Therefore, even if the present application reduces the size of each pixel area 110, it does not affect the overall display effect of the display screen. It can be seen that the present application can reduce the size of each pixel area 110, that is, by reducing the size of each pixel area 110, thereby reducing the area occupied by each pixel area 110, and then can increase the number of pixel areas 110 per unit area, which makes the image quality of the display screen more delicate and realistic, that is, this setting method can better improve the display effect of the display screen.

[0020] In addition, although the present application can reduce the size of each pixel area 110 , due to the effect of the concave lens 210 , the small-sized pixel area 110 can achieve a large light irradiation area through the concave lens 210 .

[0021] Optionally, each concave lens 210 may be made of glass, that is, the color or shape of the concave lens 210 may remain unchanged.

[0022] In another embodiment, at least one of the concave lenses 210 may be made of an electrochromic material, that is, when a voltage is applied to at least one of the concave lenses 210, the color of at least one of the concave lenses 210 may change. Specifically, when the display screen is in a display state, at least one of the concave lenses 210 may be in a light-transmitting state, that is, at this time, no voltage is applied to at least one of the concave lenses 210, so that the display screen can display the image normally; when the display screen is in an off-screen state, at least one of the concave lenses 210 changes color to a light-absorbing state, that is, at this time, when light from the external environment is irradiated onto the display screen, at least one of the concave lenses 210 may absorb the light, thereby preventing the light from being reflected from the display screen, so that the display screen achieves an integrated black effect.

[0023] Optionally, when the display screen is in the off state, the color of at least one of the concave lenses 210 can be changed to black, and the black concave lenses 210 have better light absorption and shielding effects. Optionally, the material of each concave lens 210 can be electrochromic material, and when the display screen is in the off state, each concave lens 210 can change color to a light-absorbing state, and at this time, the display screen has a better effect of being completely black.

[0024] Please refer to Figure 1 The display screen may further include a driving layer 300. In the thickness direction of the display screen, the first lens layer 200, the display layer 100 and the driving layer 300 are stacked in sequence. The driving layer 300 may specifically include a driving chip 310. The driving chip 310 may drive the pixel area 110 to emit light. Optionally, the display screen may further include a signal control line, which may be electrically connected to each concave lens 210, and the signal control line is connected to the driving layer 300. The signal control line may transmit current, that is, the driving layer 300 may drive the concave lens 210 to change color through the signal control line.

[0025] In another embodiment, please refer to Figure 2, the display screen may include two signal control lines, specifically, the display screen may include a horizontal signal control line 410 and a vertical signal control line 420, the extension direction of the horizontal signal control line 410 intersects with the extension direction of the vertical signal control line 420, the horizontal signal control line 410 and the vertical signal control line 420 are electrically connected to each concave lens 210 respectively, and the horizontal signal control line 410 and the vertical signal control line 420 are connected to the driving layer 300, and the driving layer 300 can drive the concave lens 210 to change color through the horizontal signal control line 410 and the vertical signal control line 420. Specifically, the signal output terminal 311 on the driving chip 310 is connected to one end of the horizontal signal control line 410 and one end of the vertical signal control line 420, and the signal input terminal on the driving chip 310 is connected to the other end of the horizontal signal control line 410 and the other end of the vertical signal control line 420, and the driving chip 310 drives the concave lens 210 to change color through the horizontal signal control line 410 and the vertical signal control line 420.

[0026] In this embodiment, one of the horizontal signal control line 410 and the vertical signal control line 420 can act as a control switch, and the other is used to transmit current, that is, the one is used to control the color change on or off signal of each concave lens 210, and the other is used to control the specific color change signal of each concave lens 210. Specifically, when the one is in the on state and the other is transmitting current, each concave lens 210 will change color, and when the one is in the non-conducting state, even if the other is still transmitting current, each concave lens 210 will not change color. It can be seen that when the driving layer 300 drives the concave lens 210 to change color through the horizontal signal control line 410 and the vertical signal control line 420, the horizontal signal control line 410 and the vertical signal control line 420 can cooperate with each other to play a role in double protection and preventing misoperation.

[0027] Optionally, in order to increase the contact area between the horizontal signal control line 410 and the vertical signal control line 420 and each concave lens 210, thereby ensuring the stability of the electrical connection, the horizontal signal control line 410 and the vertical signal control line 420 can be embedded in each concave lens 210. At this time, while ensuring the stability of the electrical connection, each concave lens 210 can protect the horizontal signal control line 410 and the vertical signal control line 420 so that the horizontal signal control line 410 and the vertical signal control line 420 are not exposed.

[0028] Optionally, since the first lens layer 200 includes a plurality of concave lenses 210 arranged in an array, that is, the plurality of concave lenses 210 can be arranged horizontally and vertically, the plurality of concave lenses 210 located in the same row can be connected in series via a horizontal signal control line 410, and the plurality of concave lenses 210 located in the same column can be connected in series via a vertical signal control line 420. It can be seen that the number of horizontal signal control lines 410 and the number of vertical signal control lines 420 can both be multiple.

[0029] When multiple horizontal signal control lines 410 and multiple vertical signal control lines 420 are all in the on state, each concave lens 210 can change color; when one of the multiple horizontal signal control lines 410 and one of the multiple vertical signal control lines 420 are all in the on state, a concave lens 210 located at the intersection of the horizontal signal control line 410 and the vertical signal control line 420 can change color, that is, this setting method can accurately control the color change of some of the multiple concave lenses 210.

[0030] It can be seen that this allows the display screen disclosed in the present application to adapt to a variety of scenarios. For example, when a user is making a call, a part of the area can be in an off-screen state, and another part of the area can be in a display state. For example, the other part of the area can display an on-hook button, a keyboard, and a call duration, that is, a part of the concave lens 210 is controlled to change color to a light-absorbing state, and another part of the concave lens 210 is controlled to be in a light-transmitting state. At the same time, since a horizontal signal control line 410 and a vertical signal control line 420 can connect multiple concave lenses 210, the connection method between the driver chip 310 and the concave lens 210 is relatively simple.

[0031] Optionally, refer to Figure 1 A connection portion 220 may be provided between two adjacent concave lenses 210, and the connection portion 220 may connect the two adjacent concave lenses 210. The connection portion 220 may include a first connection portion provided along the extension direction of the horizontal signal control line 410 and a second connection portion provided along the extension direction of the vertical signal control line 420, so that a portion of the horizontal signal control line 410 may be embedded in the first connection portion, and a portion of the vertical signal control line 420 may be embedded in the second connection portion. It can be seen that a portion of the horizontal signal control line 410 and a portion of the vertical signal control line 420 are both embedded in the connection portion 220 to ensure that a portion of the horizontal signal control line 410 and a portion of the vertical signal control line 420 are not exposed, that is, the connection portion 220 can protect the horizontal signal control line 410 and the vertical signal control line 420 located outside each concave lens 210. Of course, there may be no connection portion 220 between two adjacent concave lenses 210.

[0032] Optionally, the material of the connecting portion 220 and the material of the concave lens 210 may be different.

[0033] In another embodiment, the material of the connecting portion 220 is the same as that of the concave lens 210 , that is, the connecting portion 220 and the concave lens 210 can be made integrally, and the connecting portion 220 can also be electrochromic to further improve the integrated black effect of the display screen.

[0034] Optionally, the display screen may further include a second lens layer 500, which is disposed between the first lens layer 200 and the display layer 100, and the second lens layer 500 includes a plurality of convex lenses 510 arranged in an array, each pixel region 110 faces each convex lens 510 in a one-to-one correspondence, and each convex lens 510 faces each concave lens 210 in a one-to-one correspondence. At this time, the light emitted by the pixel region 110 may first be irradiated onto the convex lens 510, and the convex lens 510 may gather the light at the concave lens 210, that is, the second lens layer 500 may improve the utilization rate of the light emitted by the pixel region 110, and at the same time may protect the pixel region 110. Of course, the display screen may also not include the second lens layer 500.

[0035] Optionally, the refractive index of at least one of the convex lenses 510 may be greater than 1.5.

[0036] In another embodiment, the refractive index of at least one of the convex lenses 510 may be between 1.0 and 1.5, that is, the refractive index of the convex lens 510 is relatively small, so that the convex lens 510 can have a more obvious light-gathering effect. Optionally, the materials of the convex lenses 510 may be inorganic polymer materials or organic polymer materials.

[0037] Optionally, the concave lens 210 has a first surface 211 away from the pixel region 110, the first surface 211 is the light emitting surface of the concave lens 210, and the edge of the first surface 211 is protrudingly provided with an annular light blocking member 230, and the annular light blocking member 230 extends in a direction away from the pixel region 110. The annular light blocking member 230 is conducive to controlling the divergence area of ​​light, thereby preventing the phenomenon of color mixing when two adjacent pixel regions 110 emit light. Of course, the edge of the first surface 211 may not be protrudingly provided with an annular light blocking member 230.

[0038] Optionally, the material of the annular light blocking member 230 and the material of the concave lens 210 can be the same, that is, the material of the annular light blocking member 230 and the material of the concave lens 210 can both be organic polymer materials. In this case, the annular light blocking member 230 and the concave lens 210 can be made integrally. Since the annular light blocking member 230 is arranged at the edge of the concave lens 210, when the light passing through the concave lens 210 reaches the outer surface of the annular light blocking member 230, due to the large incident angle of this part of the light, this part of the light will basically undergo total reflection, which enables the annular light blocking member 230 to achieve the effect of blocking light. Of course, the material of the annular light blocking member 230 and the material of the concave lens 210 can also be different, so that the annular light blocking member 230 can better block the light.

[0039] Optionally, in the thickness direction of the display screen, the orthographic projection area of ​​the concave lens 210 can be less than or equal to the orthographic projection area of ​​the pixel area 110, that is, at this time, the orthographic projection contour line of the concave lens 210 can be located within the orthographic projection contour line of the pixel area 110 or the orthographic projection contour lines of the two can overlap.

[0040] In another embodiment, in the thickness direction of the display screen, the orthographic projection area of ​​the concave lens 210 is larger than the orthographic projection area of ​​the pixel region 110, and the orthographic projection contour line of the pixel region 110 is located within the orthographic projection contour line of the concave lens 210, that is, at this time, the concave lens 210 corresponding to the pixel region 110 can completely cover the pixel region 110, so that the concave lens 210 can obtain more light emitted by the pixel region 110, thereby further improving the light utilization rate of the pixel region 110.

[0041] Optionally, at least one of the concave lenses 210 may be a single-sided concave lens.

[0042] In another embodiment, at least one of the concave lenses 210 can be a double-sided concave lens, which makes the divergence angle of the light emitted from the pixel area 110 corresponding to the double-sided concave lens larger after passing through the double-sided concave lens, thereby making the light-emitting area of ​​the small-sized pixel area 110 used in the present application larger.

[0043] Optionally, each concave lens 210 may be a double-sided concave lens, which makes the light-emitting area of ​​each pixel region 110 larger, so as to achieve a better display effect of the display screen.

[0044] Optionally, the pixel density of the display screen may be between 300 and 500. In another embodiment, the pixel density of the display screen may be between 500 and 700, that is, the PPI (Pixels Per Inch, the number of pixel areas per inch) of the display screen is large, which makes the image quality of the display screen better and the display more delicate.

[0045] Optionally, refer to Figure 1 The display screen may further include a cover layer 610, a polarizer 630, a touch layer 640 and an encapsulation layer 650 stacked in sequence in the thickness direction of the display screen. The encapsulation layer 650 may be stacked on the first lens layer 200. The cover layer 610 and the polarizer 630 may be bonded together by an adhesive layer 620. The adhesive layer 620 may be an optical adhesive. The cover layer 610 serves as a peripheral structure of the display screen, which may protect the above-mentioned other functional layers of the entire display screen. The polarizer 630 has the functions of resisting ultraviolet rays and blocking reflected light. The touch layer 640 is used to realize the touch function of the display screen. The encapsulation layer 650 is used to protect the pixel area 110 and has the function of blocking water and oxygen.

[0046] Optionally, the present application further discloses an electronic device, which includes a housing and the display screen mentioned above, wherein the display screen is connected to the housing.

[0047] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
