Description

Technical Field

[0001] This application belongs to the field of display device technology, and particularly relates to display panels and display devices. Background Technology

[0002] With the increasing number of nearsighted people in my country, eye protection technology has become one of the hot research topics in the display industry. One eye protection solution involves placing a defocusing lens on the light-receiving side of the eyeball. This allows light from the central area of ​​the defocusing lens to focus normally on the retina, while light from the non-central area is refracted by the defocusing lens and focuses in front of the retina, creating myopia defocus. When the retina perceives the defocus blur, it can inhibit the elongation of the eye axis, thereby achieving the effect of slowing down myopia.

[0003] In related technologies, there is a defocus display device that emits light of a positive defocus wavelength, thereby forming a defocused surface in the human eye. However, the display devices in these technologies can only meet the needs of users who require viewing defocused images, and their applicability is limited.

[0004] Therefore, improvements to existing technologies are necessary.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0006] This application provides 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 view out-of-focus images, resulting in poor applicability.

[0008] The display panel has a non-defocus display state and a defocus display state. When the display panel is in the non-defocus display state, the red sub-pixel, green sub-pixel, and blue sub-pixel emit light of the corresponding primary color's focal wavelength, so that the light emitted by the display panel is imaged on the viewer's retina. When the display panel is in the defocus display state, the red sub-pixel, green sub-pixel, and blue sub-pixel emit light of the corresponding primary color's positive defocus wavelength, so that the light emitted by the display panel is imaged in front of the viewer's retina. The focal wavelength is greater than the corresponding primary color's positive defocus wavelength.

[0009] In one possible implementation, the sub-pixel includes at least one set of secondary sub-pixels, each set of secondary sub-pixels including a positive defocus secondary sub-pixel and a negative defocus secondary sub-pixel.

[0013] In one possible implementation, the sub-pixel further includes a focal sub-pixel, which is used to directly emit light at the focal wavelength corresponding to the primary color;

[0014] When the display panel is in a non-defocused display state, the focus sub-pixel emits light; when the display panel is in a defocused display state, the focus sub-pixel turns off.

[0015] In one possible implementation, the sub-pixel includes at least one set of secondary sub-pixels, each set of secondary sub-pixels including a positive defocus secondary sub-pixel and a positive focus secondary sub-pixel, wherein the positive defocus secondary sub-pixel is used to emit light of a corresponding positive defocus wavelength, and the positive focus secondary sub-pixel is used to directly emit light of a corresponding standard emission wavelength.

[0016] When the display panel is in a non-defocus display state, the positive focus secondary sub-pixel emits light, and the positive defocus secondary sub-pixel is turned off; when the display panel is in a defocus display state, the positive focus secondary sub-pixel is turned off, and the positive defocus secondary sub-pixel emits light.

[0017] In one possible implementation, the sub-pixel includes multiple sets of secondary sub-pixels, each set of secondary sub-pixels including a positive defocus secondary sub-pixel and a negative defocus secondary sub-pixel. The multiple positive defocus secondary sub-pixels are respectively used to emit light of a positive defocus wavelength corresponding to a primary color, and the multiple negative defocus secondary sub-pixels are respectively used to emit light of a negative defocus wavelength corresponding to a primary color. Each positive defocus secondary sub-pixel and each negative defocus secondary sub-pixel can be turned on and off independently.

[0018] When the display panel is in a non-defocus display state, at least one set of positive and negative defocus sub-pixels of sub-pixels emit light simultaneously, and the sub-pixels emit light equivalent to the positive focus wavelength of the corresponding primary color; when the display panel is in a defocus display state, the positive defocus sub-pixel of the set of sub-pixels emits light, the negative defocus sub-pixel is turned off, and the sub-pixel emits light corresponding to the positive defocus wavelength of the primary color.

[0019] In one possible implementation, the sub-pixel further includes a focal sub-pixel, which is used to directly emit light of the corresponding standard emission wavelength.

[0020] In one possible implementation, the display panel further includes a control unit for controlling the opening and closing of the negative defocus sub-pixel and the positive focus sub-pixel.

[0021] In one possible implementation, the panel body has multiple display areas arranged sequentially from the center to the periphery, and the variation trend of the positive defocus wavelength of the same primary color increases sequentially from the center to the periphery according to the position of the display area.

The display panel simultaneously satisfies the needs of users viewing both defocused and defocused images, has high applicability, and solves the problem that display devices can only meet the needs of users who need to view defocused images, resulting in poor applicability.

[0039] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

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

[0041] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0042] This application provides a display panel and a display device to address the problem that the display device can only meet the needs of users who require viewing out-of-focus images, resulting in poor applicability. The following description will be provided in conjunction with the accompanying drawings.

[0043] Example 1:

[0044] Please see Figure 1 This application provides a display panel, including a panel body 1, the panel body 1 having a plurality of pixel units 2, the pixel unit 2 including a plurality of sub-pixels 21, the plurality of sub-pixels 21 including red sub-pixels, green sub-pixels and blue sub-pixels;

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

[0046] By enabling the display panel to have both out-of-focus and out-of-focus display states, when a user needs to view an out-of-focus image, the sub-pixels on the display panel emit light of the corresponding primary color's focal wavelength, so that the light emitted by the display panel is imaged onto the viewer's retina; when a user needs to view an out-of-focus image, the sub-pixels on the display panel emit light of the corresponding primary color's defocus wavelength, so that the light emitted by the display panel is imaged in front of the viewer's retina. The display panel simultaneously satisfies the needs of users viewing both out-of-focus and out-of-focus images, offering high applicability and solving the problem that display devices can only meet the needs of users who need to view out-of-focus images, resulting in poor applicability.

[0047] Please see Figure 1 In this embodiment, the panel body 1 is rectangular, with the central display area being rectangular and the outer display area being a rectangular ring with the same center as the central display area. In some embodiments of this application, the central display area is circular, and the outer display area is a circular ring concentric with the central display area. The display areas are named A1, A2...A1 from the center to the periphery. n The difference between the focal wavelength of a sub-pixel and the focal wavelength of the corresponding primary color is the deviation wavelength. The deviation wavelength increases sequentially from the center to the periphery of the display area, and all sub-pixels in the same area have the same deviation wavelength.

[0048] By setting multiple display areas with different orientations from the inside to the outside on the panel body 1, and setting the deviation wavelength of the display areas to increase sequentially from the center to the periphery, when the user views the display panel, the light emitted from the central display area of ​​the display panel is normally imaged on the retina, while the light emitted from the peripheral display areas of the display panel is imaged in front of the retina, causing the retina to perceive 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 light of the red focal wavelength R. λ The green sub-pixel emits light of a red focal wavelength G. λ The blue sub-pixel emits light of the red focal wavelength B. λ In this embodiment, R λ =625nm, G λ =525nm, B λ =465nm. When the display panel is in defocus display mode, the red sub-pixel in display area A1 emits an R wave with a wavelength of positive defocus wavelength. λ-1 The light, showing the deviation wavelength λ1 = R of region A1. λ -R λ-1 The green sub-pixel in display area A2 emits a G wave with a positive defocus wavelength. λ-2 The light, showing the deviation wavelength of region A2 from the wavelength λ2 = Gλ -G λ-2 Display area A n The inner blue sub-pixel emits a B wave with a positive defocus wavelength. λ-n Light, showing the wavelength deviation λ of region A1 n =B λ -B λ-n , and λ1<λ2<……<λ n .

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

[0051] Please see Figures 1-3 Specifically, the red sub-pixel includes a positive red defocus sub-pixel and a negative red defocus sub-pixel; the green sub-pixel includes a positive green defocus sub-pixel and a negative green defocus sub-pixel; and the blue sub-pixel includes a positive blue defocus sub-pixel and a negative blue defocus sub-pixel. The positive red defocus sub-pixel within display area A1 emits a wavelength r with a positive defocus wavelength. λ-1 light, r λ-1 =R λ -λ1, the red negative defocus sub-pixel in display area A1 emits a wavelength of r with the positive defocus wavelength. λ +1 light, r λ +1=R λ +λ1; The green positive defocus sub-pixel within display area A2 emits a wavelength of g with the positive defocus wavelength. λ -2 light, g λ -2 = G λ -λ2, the green negative defocus sub-pixel in display area A2 emits g with a wavelength of negative defocus emission wavelength. λ +2 light, g λ +2 = G λ +λ2; Display area A n The inner blue defocused secondary sub-pixel emits a wavelength of b at the defocused 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 of b that is the same as the negative defocus emission wavelength. λ +n light, b λ +n=B λ +λ n .

[0052] Please see Figures 1-3 The display panel also includes a control unit. When the display panel is in out-of-focus display mode, the control unit controls the red positive out-of-focus sub-pixels and red negative out-of-focus sub-pixels to emit light simultaneously, equivalent to the red positive focus wavelength. The control unit also controls the green positive out-of-focus sub-pixels and green negative out-of-focus sub-pixels to emit light simultaneously, equivalent to the green positive focus wavelength, and the blue positive out-of-focus sub-pixels and blue negative out-of-focus sub-pixels to emit light simultaneously, equivalent to the blue positive focus wavelength, thus enabling the display panel to display a normal image. When the display panel is in out-of-focus display mode, the control unit controls the red negative out-of-focus sub-pixels, green negative out-of-focus sub-pixels, and blue negative out-of-focus sub-pixels to turn off, while keeping the red positive out-of-focus sub-pixels, green positive out-of-focus sub-pixels, and blue positive out-of-focus sub-pixels on, thus enabling the display panel to display an out-of-focus image.

[0053] It should be noted that in this embodiment, the step value D of the deviation wavelength of any adjacent display areas is the same, that is, D = λ2 - λ1 = λ3 - λ2 = ... = λ n -λ n-1 Furthermore, 1nm≤D≤10nm. In some embodiments of this application, the step value D can be selected from any one of 1nm, 2nm, 3nm, 4nm, 5nm, 6nm, 7nm, 8nm, 9nm, and 10nm. Each step value corresponds to a display panel with a certain degree of defocus, thereby meeting the usage needs of different users.

[0054] Please see Figure 11 In this embodiment, the shapes of the three sub-pixels are all rectangles. In some embodiments of this application, the shape of the sub-pixels is any one of square, circle, ellipse, triangle, and rhombus, and the shapes of the three sub-pixels in the same pixel unit are different.

[0055] Please see Figure 4 When the display panel is in defocus display mode, the light emitted from the central display area (A1) can be directly imaged onto the retina, while the light from the peripheral display areas (A2...A1) is focused onto the retina. n The light emitted by pixel unit 2, compared to light at the focal wavelength, is refracted at a greater angle when passing through the eye structure. This causes the light generated by pixel unit 2 to focus in front of the retina, forming myopic defocus. After the retina perceives the defocus blur, it can inhibit the elongation of the eye axis, thereby achieving the effect of slowing down myopia.

[0056] This application also provides a display device, which includes the display panel described above. Since this display device has the aforementioned display panel, it possesses at least some or all of the beneficial effects of the aforementioned display panel, which will not be elaborated upon here.

[0057] Example 2:

[0058] Please see Figure 5 The difference between this embodiment and embodiment 2 is that the sub-pixels are different. In this embodiment, the sub-pixels also include a focal secondary sub-pixel 213, which is used to directly emit light of the focal wavelength of the corresponding primary color.

[0059] Please see Figure 5 and Figure 6 Specifically, the red sub-pixel includes the red focal length sub-pixel, which is used to emit the red focal length wavelength R. λ The light emitted by the green sub-pixel includes a green focal length secondary sub-pixel, which is used to emit the green focal length wavelength G. λ The light emitted by the blue sub-pixel includes a blue focal length secondary sub-pixel, which is used to emit the blue focal length wavelength B. λ The light.

[0060] When the display panel is in out-of-focus display mode, the control unit controls all three sub-pixels—positive focus sub-pixels, positive defocus sub-pixels, and negative defocus sub-pixels—to be turned on. When the display panel is in out-of-focus display mode, the control unit controls the positive focus sub-pixels and negative defocus sub-pixels of each sub-pixel to be turned off, while keeping the positive defocus sub-pixels on.

[0061] By setting the focal second sub-pixel 213 and enabling it to emit light of the corresponding primary color focal wavelength, the brightness of the display panel when displaying a normal image is improved, thus enhancing the display effect of the display panel.

[0062] Example 3:

[0063] Please see Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that the sub-pixels are different. In this embodiment, sub-pixel 21 includes a group of secondary sub-pixels. Each group of secondary sub-pixels includes a positive defocus secondary sub-pixel 211 and a positive focus secondary sub-pixel 213. The positive defocus secondary sub-pixel 211 is used to emit light of the corresponding positive defocus wavelength, and the positive focus secondary sub-pixel 213 is used to directly emit light of the corresponding primary color's positive focus wavelength.

[0064] When the display panel is in out-of-focus display mode, the control unit controls the positive out-of-focus sub-pixels of each sub-pixel to turn off, and controls the positive focus sub-pixels to turn on. When the display panel is in out-of-focus display mode, the control unit controls the positive out-of-focus sub-pixels of each sub-pixel to turn on, and controls the positive focus sub-pixels to turn off.

[0065] By including a positive defocus secondary sub-pixel 211 and a positive focus secondary sub-pixel 213 in the secondary sub-pixel range, and controlling the opening and closing of the positive defocus secondary sub-pixel 211 and the positive focus secondary sub-pixel 213 in the secondary sub-pixel range by the control unit, damage to the positive defocus secondary sub-pixel 211 caused by prolonged opening can be reduced, thereby avoiding affecting the display effect of the display panel in defocus mode.

[0066] Example 4:

[0067] Please see Figure 9 and Figure 10 The difference between this embodiment and Embodiment 1 lies in the sub-pixels. In this embodiment, the sub-pixels include multiple groups of secondary sub-pixels, which are sequentially named SP1, SP2...SP N Each group of sub-pixels includes a positive defocus sub-pixel 211 and a negative defocus sub-pixel 212. Multiple positive defocus sub-pixels 211 are used to emit light of a positive defocus wavelength corresponding to a primary color, and multiple negative defocus sub-pixels 212 are used to emit light of a negative defocus wavelength corresponding to a primary color. Each positive defocus sub-pixel 211 and negative defocus sub-pixel 212 can be turned on and off independently.

[0068] Each group of secondary sub-pixels has an offset wavelength. The offset wavelengths of positive defocus secondary sub-pixels 211 and negative defocus secondary sub-pixels 212 in the same group are the same. Specifically, the red positive defocus secondary sub-pixels of the secondary sub-pixel group SP1 in the display area A1 emit a positive defocus wavelength r. λ-1-SP1 The light emitted by the corresponding red negative defocus sub-pixel has a negative defocus wavelength r. λ The light of +1+SP1, the offset wavelength λ of the secondary sub-pixel group SP1 within the display area A1. SP1 =R λ -λ1-r λ-1-SP1 =r λ +1+SP1-R λ -λ1; The green positive defocused secondary sub-pixel of the secondary sub-pixel group SP2 within the display area A2 emits a positive defocus wavelength g. λ The light of -2-SP2 corresponds to the green negative defocus sub-pixel emitting a negative defocus wavelength g. λ The light of +2+SP2, the offset wavelength λ of the secondary sub-pixel group SP1 within display area A1. SP2 =R λ -λ2-r λ-2-SP2 =r λ +2+SP2-R λ -λ2; Display area A n Inner sub-pixel group SP N The blue defocused secondary pixel emits a wavelength b that is positively defocused. λ-n-SPN The light emitted by the corresponding blue negative defocus sub-pixel has a negative defocus wavelength b. λ+n+SPN of light, display area A n Inner sub-pixel group SP N offset 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 offset wavelength of any adjacent sub-pixel group is the same, that is, d = λ. SP2 -λ SP1 =λ SP3 -λ SP2 =……=λ SPN -λ SPN-1 .

[0070] Please see Figure 9 and Figure 10 The control unit can control all positive defocus sub-pixels 211, all positive focus sub-pixels 213, and all negative defocus sub-pixels 212. When the display panel is in out-of-focus display mode, the control unit controls all positive defocus sub-pixels 211, 213, and 212 to be turned on, and the display panel can display a normal image. When the display panel is in out-of-focus display mode, the control unit controls all positive focus sub-pixels 213 and 212 to be turned off, and only controls the positive defocus sub-pixels 211 of the same sub-pixel group in all display areas to be turned on. For example, it controls all display areas (A1, A2...A ... n When all the sub-pixels SP1 in the sub-pixel group are turned on, the positive defocus sub-pixels 211 emit defocus light, thereby enabling the display panel to display the defocused image.

[0071] When it is necessary to switch the defocus level, the positive defocus sub-pixels 211 that are currently active in all display areas are turned off by controlling the switch, and the positive defocus sub-pixels 211 of another group of sub-pixels with the same name in all display areas are turned on by controlling the switch. For example, the positive defocus sub-pixels 211 of sub-pixel group SP1 in all display areas are turned off, and the positive defocus sub-pixels 211 of sub-pixel group SP2 in all display areas are turned on, thereby realizing the real-time adjustment of the defocus level of the display panel.

[0072] By setting multiple groups of sub-pixels and making each group of sub-pixels have different offset wavelengths, when the display panel is displaying an out-of-focus image, the positive out-of-focus sub-pixels 211 of different groups can be switched on by controlling the switch, thereby realizing real-time adjustment of the out-of-focus level of the display panel.

[0073] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0074] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
