[0039] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0040] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0042] The embodiments of the present application provide a display panel and a display device to solve the problem that the display device can only meet the needs of users who need to watch out-of-focus images and has poor applicability.

[0043] Embodiment 1:

[0044] See also Figure 1 , an embodiment of the present application provides a display panel, including a panel body 1, wherein the panel body 1 has a plurality of pixel units 2, wherein the pixel unit 2 includes a plurality of sub-pixels 21, wherein the plurality of sub-pixels 21 include red sub-pixels, green sub-pixels, and blue sub-pixels;

[0045] The display panel has a non-defocused display state and a defocused display state. When the display panel is in the non-defocused display state, the red sub-pixel, the green sub-pixel and the blue sub-pixel respectively emit light of the positive-focus wavelength of the corresponding primary color, so that the light emitted by the display panel is imaged on the retina of the viewer; when the display panel is in the defocused display state, the red sub-pixel, the green sub-pixel and the blue sub-pixel respectively emit light of the positive-defocus wavelength of the corresponding primary color, so that the light emitted by the display panel is imaged in front of the retina of the viewer, and the positive-focus wavelength is greater than the positive-defocus wavelength of the corresponding primary color.

[0046] By making the display panel have a non-defocused display state and a defocused display state, when the user needs to watch a non-defocused picture, the sub-pixels on the display panel respectively emit light of the positive focus wavelength of the corresponding primary color, so that the light emitted by the display panel is imaged on the retina of the viewer; when the user needs to watch a non-defocused picture, the sub-pixels on the display panel respectively emit light of the positive defocused wavelength of the corresponding primary color, so that the light emitted by the display panel is imaged in front of the retina of the viewer; the display panel satisfies both users who watch non-defocused pictures and users who watch defocused pictures, has high applicability, and solves the problem that the display device can only meet the needs of users who need to watch defocused pictures and has poor applicability.

[0047] See also Figure 1 In this embodiment, the panel body 1 is set in a rectangular shape, the central display area is set in a rectangular shape, and the outer display area is set in a rectangular ring with the same center as the central display area. In some embodiments of the present application, the central display area is set in a circular shape, and the outer display area is set in a circular ring concentric with the central display area. The display areas are named A from the center to the periphery. 1 , A 2 ...A n The difference between the positive focus wavelength of the sub-pixel and the positive defocus wavelength of the corresponding primary color is the deviation wavelength, and the deviation wavelength increases from the center to the periphery according to the position of the display area, and the deviation wavelength of all sub-pixels in the same area is the same.

[0048] By setting a plurality of display areas that are different from the inside to the outside on the panel body 1, and setting the preset deviation wavelengths of the display areas to increase from the center to the periphery, when the user watches the display panel, the light emitted from the central display area of ​​the display panel is normally imaged on the retina, and the light emitted from the peripheral display area of ​​the display panel is imaged in front of the retina, so that the retina perceives defocus blur, thereby achieving the effect of reducing myopia.

[0049] Specifically, when the display panel is in a non-defocused display state, the red sub-pixel emits red positive-focus wavelength light R λ , the green sub-pixel emits red positive-focus wavelength light G λ , the blue sub-pixel emits red positive-focus wavelength light B λ In this embodiment, R λ =625nm, G λ =525nm, B λ =465nm. When the display panel is in the non-defocused display state, the display area A 1 The red sub-pixel emits a positive defocus wavelength R λ-1 Light, display area A 1 The shift wavelength λ 1 =R λ -Rλ-1 , display area A 2 The inner green sub-pixel emits G at a wavelength of positive defocus wavelength. λ-2 Light, display area A 2 The shift wavelength λ 2 =R λ -R λ-2 , display area A n The inner blue sub-pixel emits a B with a wavelength of positive defocus wavelength. λ-n Light, display area A 1 The shift wavelength λ n =R λ -R λ-n , and λ 1 <λ 2 <……<λ n .

[0050] In this embodiment, the sub-pixel 21 includes a group of sub-sub-pixels, and the sub-sub-pixel group includes a positive defocus sub-sub-pixel 211 and a negative defocus sub-sub-pixel 212. The positive defocus sub-sub-pixel 211 is used to emit light of a positive defocus wavelength corresponding to the primary color, and the negative defocus sub-sub-pixel 212 emits light of a negative defocus wavelength corresponding to the primary color. The negative defocus light emission wavelength is the sum of the standard light emission wavelength of the sub-pixel 21 and the preset deviation wavelength of the display area where the sub-pixel 21 is located.

[0051] See also Figure 1-Figure 3 Specifically, the red sub-pixel includes a red positive defocus sub-pixel and a red negative defocus sub-pixel, the green sub-pixel includes a green positive defocus sub-pixel and a green negative defocus sub-pixel, and the blue sub-pixel includes a blue positive defocus sub-pixel and a blue negative defocus sub-pixel. Display area A 1 The red positive defocus sub-pixel emits a wavelength r of positive defocus wavelength. λ-1 Light, λ-1 =R λ -λ 1 , display area A 1 The red negative defocused sub-pixel emits a positive defocused wavelength r λ+1 Light, λ+1 =R λ +λ 1 ; Display area A 2 The inner green positive defocus sub-pixel emits g with a wavelength of positive defocus wavelength λ-2 Light, g λ-2 =G λ -λ 2 , display area A 2 The green negative defocus sub-pixel emits a wavelength of g with a negative defocus wavelength. λ+2 Light, g λ+2 =G λ +λ 2 ; Display area An The inner blue positive defocus sub-pixel emits a wavelength b of the positive defocus wavelength λ-n Light, b λ-n =B λ -λ n , display area A n The inner blue negative defocus sub-pixel emits a wavelength b of negative defocused light. λ+n Light, b λ+n =B λ +λ n .

[0052] See also Figure 1-Figure 3 The display panel also includes a control unit. When the display panel is in a non-defocused display state, the control unit controls the red positive defocused sub-pixel and the red negative defocused sub-pixel to emit light simultaneously and equivalent to the standard red light wavelength, controls the green positive defocused sub-pixel and the green negative defocused sub-pixel to emit light simultaneously and equivalent to the standard green light wavelength, and controls the blue positive defocused sub-pixel and the blue negative defocused sub-pixel to emit light simultaneously and equivalent to the standard blue light wavelength, so that the display panel can display a normal picture. When the display panel is in a defocused display state, the control unit controls the red negative defocused sub-pixel, the green negative defocused sub-pixel, and the blue negative defocused sub-pixel to be turned off, so that the red positive defocused sub-pixel, the green positive defocused sub-pixel, and the blue positive defocused sub-pixel remain turned on, so that the display panel displays a defocused picture.

[0053] It should be noted that, in this embodiment, the preset step value D of the deviation wavelength of any adjacent display areas is the same, that is, D=λ 2 -λ 1 =λ 3 -λ 2 =……=λ n -λ n-1 , and 1nm≤D≤10nm. In some embodiments of the present application, the step value D can be selected from any one of 1nm, 2nm, 3nm, 4nm, 5nm, 6nm, 7nm, 8nm, 9nm, and 10nm, and each step value corresponds to a display panel with a certain defocus degree, so as to meet the usage needs of different users.

[0054] See also Fig.11 In this embodiment, the shapes of the three sub-pixels are all rectangular. In some embodiments of the present application, the shape of the sub-pixel is any one of a square, a circle, an ellipse, a triangle, and a diamond, and the shapes of the three sub-pixels in the same pixel unit are different.

[0055] See also Figure 4 When the display panel is in the defocused display state, the central display area (A 1) can directly form an image on the retina, and the peripheral display area (A 2 ...A n ), compared with the light at the standard emission wavelength, the light at the positive defocus wavelength will be deflected at a larger angle when refracted through the structure of the eyeball, so that the light generated by the pixel unit 2 is focused in front of the retina, forming myopic defocus. After sensing the defocus blur, the retina can inhibit the elongation of the eye axis, thereby achieving the effect of slowing down myopia.

[0056] The embodiment of the present application also provides a display device, the display device comprising the display panel as described above. Since the display device comprises the display panel as described above, and since it has at least some or all of the beneficial effects of the display panel as described above, they will not be described one by one here.

[0057] Embodiment 2:

[0058] See also Figure 5 The difference between this embodiment and embodiment 2 lies in the sub-pixels. In this embodiment, the sub-pixels further include a positive-focus sub-sub-pixel 213, which is used to directly emit light of a positive-focus wavelength of a corresponding primary color.

[0059] See also Figure 5 and Figure 6 Specifically, the red sub-pixel includes a red positive focus sub-sub-pixel, and the red positive focus sub-sub-pixel is used to emit a red positive focus wavelength R λ The green sub-pixel includes a green positive focus sub-sub-pixel, and the green positive focus sub-sub-pixel is used to emit a green positive focus wavelength G λ The blue sub-pixel includes a blue positive focus sub-sub-pixel, and the blue positive focus sub-sub-pixel is used to emit a blue positive focus wavelength B λ of light.

[0060] When the display panel is in a non-defocused display state, the control unit controls the positive focus sub-sub-pixel, the positive defocused sub-sub-pixel and the negative defocused sub-sub-pixel of each sub-pixel to be all turned on. When the display panel is in a defocused display state, the control unit controls the positive focus sub-sub-pixel and the negative defocused sub-pixel of each sub-pixel to be turned off, so that the positive defocused sub-sub-pixel remains turned on.

[0061] By providing the positive-focus sub-pixel 213 and enabling the positive-focus sub-pixel 213 to emit light of a positive-focus wavelength corresponding to the primary color, the image brightness of the display panel when displaying a normal image is improved, thereby enhancing the display effect of the display panel.

[0062] Embodiment 3:

[0063] See also Figure 7 and Figure 8The difference between this embodiment and embodiment 1 lies in the different sub-pixels. In this embodiment, the sub-pixel 21 includes a group of sub-sub-pixels, each group of sub-sub-pixels includes a positive defocus sub-sub-pixel 211 and a positive focus sub-sub-pixel 213. The positive defocus sub-sub-pixel 211 is used to emit light of the corresponding positive defocus wavelength, and the positive focus sub-sub-pixel 213 is used to directly emit light of the corresponding primary color at the positive focus wavelength.

[0064] When the display panel is in a non-defocused display state, the control unit controls the positive defocused sub-sub-pixels of each sub-pixel to be turned off and the positive focus sub-sub-pixels to be turned on. When the display panel is in a defocused display state, the control unit controls the positive defocused sub-sub-pixels of each sub-pixel to be turned on and the positive focus sub-sub-pixels to be turned off.

[0065] By making the sub-pixels include a positive defocus sub-pixel 211 and a positive focus sub-pixel 213, and controlling the opening and closing of the positive defocus sub-pixel 211 and the positive focus sub-pixel 213 by a control unit, it is possible to reduce the damage of the positive defocus sub-pixel 211 caused by long-term opening of the positive defocus sub-pixel 211, thereby avoiding affecting the display effect of the display panel in the defocus mode.

[0066] Embodiment 4:

[0067] See also Fig. 9 and Fig.10 The difference between this embodiment and embodiment 1 is that the sub-pixels are different. In this embodiment, the sub-pixels include multiple groups of sub-sub-pixels, which are named SP 1 , SP 2 ……SP N Each group of sub-sub-pixels includes a positive defocus sub-sub-pixel 211 and a negative defocus sub-sub-pixel 212. The multiple positive defocus sub-sub-pixels 211 are respectively used to emit light of a positive defocus wavelength corresponding to the primary color, and the multiple negative defocus sub-sub-pixels 212 are respectively used to emit light of a negative defocus wavelength corresponding to the primary color. Each positive defocus sub-sub-pixel 211 and negative defocus sub-sub-pixel 212 can be turned on and off independently.

[0068] Each group of sub-pixels has an offset wavelength. The offset wavelengths of the positive defocus sub-pixels 211 and the negative defocus sub-pixels 212 in the same group are the same. Specifically, the display area A 1 Inner sub-pixel group SP 1 The red positive defocused sub-pixel emits a positive defocused wavelength r λ-1-SP1 The corresponding red negative defocused sub-pixel emits a negative defocused wavelength r λ+1+SP1 The light shows area A 1 Inner sub-pixel group SP 1 The shift wavelength λ SP1 =R λ -λ 1 -rλ-1-SP1 =r λ+1+SP1 -R λ -λ 1 ; Display area A 2 Inner sub-pixel group SP 2 The green positive defocused sub-pixel emits a positive defocused wavelength g λ-2-SP2 The corresponding green negative defocused sub-pixel emits a negative defocused wavelength g λ+2+SP2 The light shows area A 1 Inner sub-pixel group SP 1 The shift wavelength λ SP2 =R λ -λ 2 -r λ-2-SP2 =r λ+2+SP2 -R λ -λ 2 ; Display area A n Inner sub-pixel group SP N The blue positive defocused sub-pixel emits a positive defocused wavelength b λ-n-SPN The corresponding blue negative defocused sub-pixel emits a negative defocused wavelength b λ+n+SPN The light shows area A n Inner sub-pixel group SP N The shift wavelength λ SPN =R λ -λ n -r λ-n-SPN =r λ+n+SPN -R λ -λ n .

[0069] It should be noted that, in this embodiment, the step value d of the preset offset wavelength of any adjacent sub-pixel groups is the same, that is, d=λ SP2 -λ SP1 =λ SP3 -λ SP2 =……=λ SPN -λ SP N-1 .

[0070] See also Fig.10 and Fig.11, the control unit can control all positive defocus sub-pixels 211, all positive defocus sub-pixels 213 and all negative defocus sub-pixels 212. When the display panel is in a non-defocused display state, the control unit controls all positive defocus sub-pixels 211, all positive defocus sub-pixels 213 and all negative defocus sub-pixels 212 to turn on, and the display panel can display a normal picture. When the display panel is in a defocused display state, the control unit controls all positive defocus sub-pixels 213 and all negative defocus sub-pixels 212 to turn off, and only controls the positive defocus sub-pixels 211 of the same sub-pixel group in all display areas to turn on, for example, controlling all display areas (A 1 , A 2 ...A n ) in all sub-pixel groups SP 1 The positive defocus sub-pixel 211 is turned on, and the positive defocus sub-pixel 211 emits defocused light, so that the display panel can display a defocused picture.

[0071] When the defocus level needs to be switched, the positive defocus sub-pixels 211 in all display regions that are turned on are turned off by controlling the switch, and the positive defocus sub-pixels 211 in another sub-pixel group with the same name in all display regions are turned on by controlling the switch. For example, the sub-pixel groups SP in all display regions are controlled. 1 The positive defocused sub-pixel 211 is turned off, and then the sub-pixel groups SP in all display areas are controlled. 2 The positive defocus sub-pixel 211 is turned on, thereby achieving real-time adjustment of the defocus level of the display panel.

[0072] By setting multiple groups of sub-pixels and making each sub-pixel group have a different preset offset wavelength, when the display panel displays a defocused image, different groups of positive defocused sub-pixels 211 are switched on by controlling the switch, thereby achieving real-time adjustment of the defocus level of the display panel.

[0073] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0074] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
