Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of display technology, and in particular to a display panel and an electronic device. Background Art
[0002] OLED (organic light-emitting diode) display screens have the advantages of high contrast, high color gamut, and low power consumption, and are currently a widely used display technology. The OLED display screen includes a substrate layer and a light-emitting layer, and the substrate layer is provided with a driving circuit for driving the light-emitting layer to emit light. The light-emitting layer includes a plurality of repeating units arranged in an array, and each repeating unit includes a blue sub-pixel, a green sub-pixel, and a red sub-pixel. The blue sub-pixel is used to emit blue light, the green sub-pixel is used to emit green light, and the red sub-pixel is used to emit red light. The light emitted by the red sub-pixel, the green sub-pixel, and the green sub-pixel is mixed to form a pixel that displays the image. However, after users watch OLED displays for a long time, they are prone to visual problems such as myopia, dry eyes, and visual fatigue in middle-aged and elderly people. Summary of the Invention
[0003] Embodiments of the present application provide a display panel and an electronic device, which can improve visual problems caused by users watching the display panel for a long time.
[0004] In a first aspect, the present application provides a display panel comprising a pixel array, the pixel array comprising a plurality of sub-pixels. The plurality of sub-pixels are arranged in an array along a first direction and a second direction, the first direction and the second direction intersecting and not overlapping. The plurality of sub-pixels include blue sub-pixels, green sub-pixels, and deep red sub-pixels, the blue sub-pixels being configured to emit blue light, the green sub-pixels being configured to emit green light, and the deep red sub-pixels being configured to emit deep red light having a first peak wavelength, the first peak wavelength being greater than or equal to 650 nm and less than or equal to 900 nm.
[0005] In this way, by providing deep red photon pixels in the display panel that emit deep red light at the first peak wavelength, the display panel has an eye protection function, which can improve visual problems caused by users viewing the display panel for a long time. For example, if a child views the display panel while deep red light is irradiated into their eyes, it can effectively inhibit the growth of their eye axis and slow myopia. Alternatively, if a middle-aged or elderly person views the display panel while deep red light is irradiated into their eyes, it can improve the mitochondrial performance in their eye cells and enhance their vision.
[0006] In a possible implementation, the plurality of sub-pixels constitute a plurality of repeating units, and each repeating unit is composed of a blue sub-pixel, a green sub-pixel, and a deep red sub-pixel.
[0007] In this way, the light emitted by the blue, green, and deep red sub-pixels in each repeating unit can be mixed to form pixels that display the image, realizing the display function of the display panel. In addition, while the display panel is displaying, the deep red sub-pixels automatically emit deep red light, realizing the full-time eye protection function and further improving the eye protection effect. In addition, the color gamut area of the display panel can also be increased, which helps to improve the color performance of the display panel.
[0008] In a possible implementation, the energy ratio of deep red photon pixels, green photon pixels, and blue photon pixels is 2.87:1:1.
[0009] In this way, by controlling the currents supplied to the deep red, green, and blue sub-pixels, the energy ratio of the deep red, green, and blue sub-pixels is adjusted to 2.87:1:1, achieving a target white point to ensure a good display quality. The target white point is defined as the target white point in the 1931 CIE coordinate system, set to x = 0.3127 and y = 0.329, based on the Rec. 709 color standard. (The x-axis represents the target white point's horizontal coordinate, and the y-axis represents its vertical coordinate.)
[0010] In a possible implementation, the plurality of sub-pixels further include a red light display sub-pixel, and the red light display sub-pixel is configured to emit red light display having a second peak wavelength, where the second peak wavelength is less than 650 nm.
[0011] In this way, the display panel has an eye protection mode and a normal mode. When the display panel is in normal mode, the light emitted by the red, green, and blue sub-pixels is mixed to form pixels that display the image. At this time, the deep red sub-pixels do not emit light. When the display panel is in eye protection mode, the deep red sub-pixels emit light, which can improve visual problems. When the display panel is in eye protection mode and normal mode at the same time, the deep red sub-pixels and the display red sub-pixels emit light at the same time, which can both display content and provide eye protection.
[0012] The peak wavelength of displayed red light is shorter than the peak wavelength of deep red light, resulting in a higher power consumption of deep red sub-pixels than red sub-pixels. Consequently, the power consumption of the display panel in normal mode is lower than when the display panel is in both eye protection mode and normal mode simultaneously. Customizing the operating time of eye protection mode helps extend the display time of the display panel (when powered by a battery or other power source). Furthermore, the service life of the deep red sub-pixels can be increased.
[0013] Compared with existing OLED display screens with red light pixels with a peak wavelength of approximately 610 to 630 nm, when the deep red photon pixels and the display red photon pixels in the display panel provided by the present application emit light at the same time, the color gamut coverage of the display panel can be improved, which helps to improve the color rendering capability of the display panel.
[0014] In a possible implementation, the plurality of sub-pixels constitute a plurality of repeating units, and each repeating unit is composed of a blue sub-pixel, a green sub-pixel, a deep red sub-pixel, and a display red sub-pixel.
[0015] In this way, the light emitted by at least one of the deep red sub-pixel and the display red sub-pixel can be mixed with the light emitted by the green sub-pixel and the blue sub-pixel to form a pixel of the displayed image, which can meet display requirements. In addition, the density of the deep red sub-pixels can be increased to ensure that the deep red light reaches the user's eyes.
[0016] In a possible implementation, in each repeating unit, the deep red photon sub-pixels and the display red photon sub-pixels correspond one to one.
[0017] In this way, the density of deep red light sub-pixels and display red light sub-pixels can be the same, which helps to increase the irradiation range of deep red light and ensures that the user's eyes receive deep red light at all times.
[0018] In a possible implementation, in each repeating unit, corresponding sub-pixels displaying red light and sub-pixels displaying deep red light are arranged at intervals.
[0019] In this way, the red and deep red sub-pixels can emit light synchronously, or independently. At the same time, the display panel can display the corresponding content. Furthermore, the arrangement of the red and deep red sub-pixels can be simplified, reducing the manufacturing difficulty of the display panel.
[0020] In a possible implementation, in each repeating unit, the corresponding red photon sub-pixel and deep red photon sub-pixel are connected.
[0021] In this way, the areas occupied by the corresponding red and deep red sub-pixels can be reduced, and the number of pixels on the display panel can be increased when the area of the display panel is constant.
[0022] In a possible implementation, in each repeating unit, the deep red sub-pixel is disposed inside the corresponding red display sub-pixel.
[0023] In this way, the red sub-pixel and the deep red sub-pixel can emit light synchronously, or can emit light independently. At the same time, the display panel can display corresponding content.
[0024] In a possible implementation, in each repeating unit, the red light display sub-pixel is disposed inside the corresponding deep red light display sub-pixel.
[0025] In this way, the red sub-pixel and the deep red sub-pixel can emit light synchronously, or can emit light independently. At the same time, the display panel can display corresponding content.
[0026] In a possible implementation, in each repeating unit, the corresponding deep red sub-pixel and the display red sub-pixel are arranged side by side.
[0027] In this way, the red and deep red sub-pixels can emit light synchronously, or independently. At the same time, the display panel can display the corresponding content. Furthermore, the arrangement of the red and deep red sub-pixels can be simplified, reducing the manufacturing difficulty of the display panel.
[0028] In a possible implementation, in each repeating unit, a ratio of a total area of deep red sub-pixels to a total area of red sub-pixels is greater than or equal to 0.1 and less than or equal to 1.
[0029] In this way, the power consumption and display effect of the display panel can be effectively balanced.
[0030] In a possible implementation, the energy ratio of displaying red photon sub-pixels, green photon sub-pixels, blue photon sub-pixels, and deep red photon sub-pixels is 0.5:1:1:1.4.
[0031] In this way, by controlling the ratio of the currents supplied to the red, green, blue and deep red sub-pixels, the energy ratio of the red, green, blue and deep red sub-pixels is 0.5:1:1:1.4, thereby obtaining the target white point.
[0032] In a possible implementation, the second peak wavelength is greater than or equal to 610 nm and less than or equal to 630 nm.
[0033] In this way, the manufacturing difficulty of the red sub-pixel can be reduced, which helps to reduce the manufacturing difficulty of the display panel. In addition, the power consumption of the red sub-pixel can be reduced, which reduces the power consumption of the display panel.
[0034] In a possible implementation, the display panel includes a substrate layer and a light-emitting layer, the light-emitting layer includes a pixel array, and the substrate layer includes a driving circuit for driving the light-emitting layer to emit light.
[0035] In this way, the light-emitting layer is controlled by the substrate layer to emit light, so that information, images, etc. to be displayed can be displayed.

[0073] In related technologies, an OLED display screen includes a substrate layer and a light-emitting layer. The substrate layer is provided with a driving circuit for driving the light-emitting layer to emit light. The light-emitting layer comprises a plurality of repeating units arranged in an array. Each repeating unit includes a blue sub-pixel, a green sub-pixel, and a red sub-pixel. The blue sub-pixel is used to emit blue light, the green sub-pixel is used to emit green light, and the red sub-pixel is used to emit red light with a peak wavelength of 610nm to 630nm. The light emitted by the red sub-pixel, the green sub-pixel, and the green sub-pixel is mixed to form a pixel that displays the image. However, existing OLED displays cannot emit light that is beneficial to the user's eyes. Therefore, users who watch OLED displays for a long time are prone to visual problems such as myopia, dry eyes, and visual fatigue in middle-aged and elderly people.
[0074] Based on this, an embodiment of the present application provides a display panel 200 and an electronic device 100, wherein a deep red photon pixel RA is provided in the display panel 200, and the deep red photon pixel RA is used to emit deep red light with a peak wavelength of 650nm to 900nm, so that the display panel 200 has an eye protection function, which can improve visual problems such as myopia, dry eyes, and visual fatigue in middle-aged and elderly people caused by users watching the display panel 200 for a long time.
[0075] The electronic device 100 may include but is not limited to smart consumer electronic devices 100 such as mobile phones, tablet computers, and laptop computers, or wearable electronic devices 100 such as augmented reality (AR), virtual reality (VR), smart watches, and smart bracelets, or vehicle-mounted devices such as car computers, or may also be devices for displaying text, images, videos, etc., such as televisions.
[0076] In the embodiment of the present application, a mobile phone is taken as the electronic device 100 for example. Figure 1 As shown. Among them, Figure 1 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application.
[0077] Figure 2 for Figure 1 Exploded diagram of the electronic device shown.
[0078] See also Figure 2As shown, the electronic device 100 includes a housing 300 and a display panel 200. The housing 300 serves as the structural support component of the electronic device 100 and is used to mount the display panel 200, as well as accommodate or mount other components such as a motherboard and a battery. The display panel 200 is connected to the housing 300 and is used to display information such as text, images, and videos. The display panel 200 can be an organic light-emitting diode (OLED) display panel 200.
[0079] See also Figure 2 As shown, the electronic device 100 may further include a cover plate 400, which is located on the display side of the display panel 200. The cover plate 400 may be made of glass and may be used to protect the display panel 200. The cover plate 400 and the housing 300 together enclose a receiving space, and the display panel 200 is located within this receiving space. The cover plate 400 and the display panel 200 together constitute the display screen 600.
[0080] In some implementations, the display panel 200 may be connected to the housing 300 via a cover plate 400. In other implementations, the display panel 200 may be directly connected to the housing 300. In still other implementations, the display panel 200 may be connected to the housing 300 via a connector (not shown).
[0081] See also Figure 2 As shown, the electronic device 100 may further include a controller 500, which may be arranged on a main board of the electronic device 100. The controller 500 is electrically connected to the display panel 200. Specifically, the controller 500 is used to drive the display panel 200 to emit light. The controller 500 may also be used to power the display panel 200. Figure 2 The controller 500 is schematically represented by a rectangular frame, which does not represent the specific structure of the controller 500. Figure 2 It also only schematically expresses the position of the controller 500 in the shell 300. This application does not limit the specific position of the controller 500. It can be understood that the controller 500 can be located on the main board, and the main board can be located in the top area, or the side area or the bottom area of the shell 300. The main board can be arranged side by side with the battery inside the shell 300.
[0082] Figure 3 A schematic structural diagram of a display panel provided in an embodiment of the present application.
[0083] See also Figure 3As shown, the display panel 200 includes a substrate layer 220 and a light-emitting layer 210. The light-emitting layer 210 includes a pixel array 10 composed of multiple sub-pixels. The sub-pixels in the light-emitting layer 210 are configured to emit light. The substrate layer 220 includes a driving circuit 221 for driving the light-emitting layer 210 to emit light. Specifically, the driving circuit 221 is configured to drive the sub-pixels in the light-emitting layer 210 to emit light. Thus, by controlling the light-emitting layer 210 to emit light through the substrate layer 220, information such as text, images, and videos can be displayed.
[0084] In the embodiment of the present application, the pixel array 10 refers to the arrangement structure of light-emitting devices of different colors in the display panel 200, and does not limit the arrangement structure of the driving circuit 221 used to drive each light-emitting device. Accordingly, the sub-pixels in the embodiment of the present application refer to the light-emitting device structure, and the sub-pixels may include, but are not limited to, sub-pixels that display four different colors: red sub-pixel RB, deep red sub-pixel RA, blue sub-pixel B, and green sub-pixel G.
[0085] Figure 4 This is a schematic diagram of the architecture of the first pixel array provided in an embodiment of the present application. Figure 5 for Figure 4 Schematic diagram of the architecture of a repeating unit in a pixel array.
[0086] See also Figure 4 As shown, the pixel array 10 includes a plurality of sub-pixels. The plurality of sub-pixels are arranged in an array along a first direction X and a second direction Y, which intersect and do not overlap. The plurality of sub-pixels include a blue sub-pixel B, a green sub-pixel G, and a deep red sub-pixel RA. The blue sub-pixel B is configured to emit blue light, the green sub-pixel G is configured to emit green light, and the deep red sub-pixel RA is configured to emit deep red light having a first peak wavelength greater than or equal to 650 nm and less than or equal to 900 nm.
[0087] There is no specific limitation on the specific value of the first peak wavelength. For example, the first peak wavelength can be 650nm, 655nm, 660nm, 661nm, 665nm, 670nm, 675nm, 680nm, 685nm, 690nm, 695nm, 700nm, 705nm, 710nm, 715nm, 720nm, 725nm, 730nm, 735nm, 740nm, 745nm, 750nm, 755nm, 760nm, 765nm, 770nm, 775nm, 780nm, 785nm, 790nm, 800nm, 810nm, 815nm, 820nm, 825nm, 830nm, 835nm, 840nm, 845nm, 850nm, 855nm, 860nm, 865nm, 875nm, 875nm, 880nm, 885nm, 885nm, 890nm, 900nm, 910nm, 915nm, 920nm, 925nm, 930nm, 935nm, 940nm, 945nm, 950nm, 955nm, 960nm, 965nm, 975nm, 980nm, 985nm, 990nm, 1000nm nm, 770nm, 775nm, 780nm, 785nm, 790nm, 795nm, 800nm, 805nm, 810nm, 815nm, 820nm, 825nm, 830nm, 835nm, 840nm, 845nm, 850nm, 855nm, 860nm, 865nm, 870nm, 875nm, 875.6nm, 880nm, 885nm or 900nm, etc.
[0088] For example, Figure 4 As shown, there are multiple deep red photon pixels RA, and the peak wavelength of deep red light emitted by the multiple deep red photon pixels RA is the same, which can reduce the manufacturing difficulty of the display panel 200 and better control the power consumption of the display panel 200. In some implementations, some of the multiple deep red photon pixels RA can emit deep red light with the same peak wavelength, and another portion can emit deep red light with different peak wavelengths. In other implementations, the multiple deep red photon pixels RA can also emit deep red light with different peak wavelengths.
[0089] By providing a deep red photon sub-pixel RA in the display panel 200 that emits deep red light having a first peak wavelength, the display panel 200 has an eye protection function, which can improve visual problems such as myopia, dry eyes, and visual fatigue in the elderly caused by prolonged viewing of the display panel 200. For example, if a child views the display panel 200 while being exposed to deep red light, the child's eye axis can be effectively inhibited from growing, thereby reducing myopia. Alternatively, if a middle-aged or elderly person views the display panel 200 while being exposed to deep red light, the mitochondrial performance in the elderly person's eye cells can be improved, thereby enhancing vision.
[0090] See also Figure 4 As shown, multiple sub-pixels form multiple repeating units 11, and each repeating unit 11 is composed of a blue sub-pixel B, a green sub-pixel G, and a deep red sub-pixel RA. It can be understood that the pixel array 10 is composed of multiple repeating units 11, and each repeating unit 11 is composed of three different color sub-pixels: blue sub-pixel B, green sub-pixel G, and deep red sub-pixel RA.
[0091] During operation of the display panel 200, the light emitted by the blue sub-pixel B, green sub-pixel G, and deep red sub-pixel RA in each repeating unit 11 can be mixed to form pixels that display an image, thereby realizing the display function of the display panel 200. In addition, while the display panel 200 is displaying, the deep red sub-pixel RA automatically emits deep red light, realizing a full-time eye protection function and further improving the eye protection effect.
[0092] Since the peak wavelength of the deep red light emitted by the deep red sub-pixel RA is longer, the color gamut area of the display panel 200 can be increased, which helps to improve the color expression capability of the display panel 200.
[0093] Figure 6 To contain Figure 4 Schematic diagram of the color gamut of the display panel with the pixel array shown and the existing display panel, Figure 7a is a spectrum diagram of a display panel in the prior art, Figure 7b To contain Figure 4 Spectral diagram of a display panel with the pixel array shown.
[0094] exist Figure 6 In the BT2020 color gamut, a1 refers to the BT2020 color gamut, and a2 refers to the BT2020 color gamut. Figure 4 The area of the BT2020 color gamut covered by the display panel of the pixel array shown, a3 refers to the area of the BT2020 color gamut covered by the existing display panel. Figures 6 to 7b It can be seen that the BT2020 color gamut coverage of the existing display panel is 72.16%, including Figure 4 The BT2020 color gamut coverage of the display panel 200 of the pixel array 10 shown is 76.19%, which helps to improve the color representation capability of the display panel 200.
[0095] When the pixel array 10 is composed of three sub-pixels of different colors, namely, deep red photon pixel RA, green photon pixel G, and blue photon pixel B, the pixel array 10 may include but is not limited to a PenTile arrangement (diamond arrangement), a Delta arrangement, a Pearl arrangement (pearl arrangement), a Triangular PenTile arrangement (Zhou Dongyu arrangement), a hexagonal crystal pixel arrangement (honeycomb arrangement), a tripod-shaped pixel arrangement, or a crystal diamond arrangement, etc.
[0096] For example, Figure 4 As shown, the arrangement of the deep red photon pixel RA, the green photon pixel G and the blue photon pixel B is the same as that of the red pixel, the green pixel and the blue pixel in the diamond arrangement, and the position of the deep red photon pixel RA is the same as that of the red pixel.
[0097] For example, see Figure 5As shown, each repeating unit 11 includes one blue sub-pixel B, four green sub-pixels G, and four deep red sub-pixels RA. Along the circumference of the blue sub-pixel B, the four green sub-pixels G are spaced around the blue sub-pixel B, and the four deep red sub-pixels RA are spaced around the blue sub-pixel B. The deep red sub-pixels RA and the green sub-pixels G are arranged alternately.
[0098] Continue to see Figure 5 As shown, two adjacent repeating units 11 share two deep red sub-pixels RA and one green sub-pixel G, thus improving the utilization of the deep red sub-pixels RA and the green sub-pixel G.
[0099] It can be understood that the pixel array 10 includes a plurality of first pixel rows and a plurality of second pixel rows, the first pixel rows and the second pixel rows are alternately arranged along the first direction X, the first pixel rows include a plurality of deep red sub-pixels RA and a plurality of green sub-pixels G alternately arranged along the second direction Y, and the second pixel rows include a plurality of blue sub-pixels B and a plurality of green sub-pixels G alternately arranged along the second direction Y.
[0100] For example, Figure 5 As shown, the shape of the blue sub-pixel B is a square. However, the shape of the blue sub-pixel B may also be other shapes, such as a circle or an ellipse.
[0101] For example, Figure 5 As shown, the shape of the green sub-pixel G is a square. However, the shape of the green sub-pixel G may also be other shapes, such as a circle or an ellipse.
[0102] For example, Figure 5 As shown, the deep red photon pixel RA is in a square shape. However, the deep red photon pixel RA may also be in other shapes, such as a circle or an ellipse.
[0103] For example, the area of the blue sub-pixel B is larger than the area of the deep red sub-pixel RA, which in turn is larger than the area of the green sub-pixel, which in turn is smaller than the area of the deep red sub-pixel RA. Of course, the area relationship between the blue sub-pixel B, the green sub-pixel G, and the deep red sub-pixel RA may also be other relationships.
[0104] In some possible implementations, the energy ratio of the deep red sub-pixel RA, the green sub-pixel G, and the blue sub-pixel B may be 2.87:1:1, and the target white point may be obtained, so that the display effect of the display panel 200 meets the requirements.
[0105] The target white point refers to the target white point set according to the Rec.709 color standard, with the coordinates of the target white point in the 1931 CIE coordinate system being x=0.3127 and y=0.329, where x is the horizontal coordinate of the target white point and y is the vertical coordinate of the target white point.
[0106] The energy ratio refers to the integral ratio of the spectrum corresponding to each sub-pixel in the spectrum diagram of the display panel 200, in other words, the integral of the area of the spectrum of each sub-pixel. Figure 7b From the spectrum diagram shown, it can be obtained that the energy ratio of deep red photon pixel RA, green photon pixel G and blue photon pixel B is 2.87:1:1.
[0107] For example, the currents supplied to the deep red sub-pixel RA, the green sub-pixel G and the blue sub-pixel B can be controlled so that the energy ratio of the deep red sub-pixel RA, the green sub-pixel G and the blue sub-pixel B is a preset ratio, for example, the preset ratio is 2.87:1:1.
[0108] It should be noted that the energy ratio of the deep red sub-pixel RA, the green sub-pixel G, and the blue sub-pixel B may also be controlled to be a preset ratio by other methods.
[0109] It should also be noted that when the target white point's coordinates are other than "x = 0.3127, y = 0.329," the energy ratio of the deep red sub-pixel RA, green sub-pixel G, and blue sub-pixel B changes. In other words, when the energy ratio of the deep red sub-pixel RA, green sub-pixel G, and blue sub-pixel B is different, the coordinates of the target white point change, and a corresponding display effect can be achieved. For example, the energy ratio of the deep red sub-pixel RA, green sub-pixel G, and blue sub-pixel B can also be 2.7:1:1.
[0110] Figure 8 This is a schematic diagram of the architecture of the second pixel array provided in an embodiment of the present application. Figure 9 for Figure 8 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0111] Figure 8 and Figure 4 The difference is that the multiple sub-pixels in pixel array 10 also include a red display sub-pixel RB, which is configured to emit red display light having a second peak wavelength less than 650nm. Specifically, pixel array 10 is composed of four different sub-pixels: a blue sub-pixel B, a green sub-pixel G, a deep red sub-pixel RA, and a red display sub-pixel RB. Pixel array 10 can emit two red lights with different peak wavelengths.
[0112] For example, the second peak wavelength may be greater than or equal to 610 nm and less than or equal to 630 nm. This can reduce the manufacturing difficulty of the red sub-pixel RB, thereby helping to reduce the manufacturing difficulty of the display panel 200. Furthermore, the power consumption of the red sub-pixel RB can be reduced, thereby reducing the power consumption of the display panel 200.
[0113] In some implementations, the second peak wavelength may be greater than 630 nm and less than 650 nm. In other implementations, the second peak wavelength may be less than 610 nm.
[0114] It is understandable that the deep red sub-pixel RA and the display red sub-pixel RB in each red light image group can emit light simultaneously, or the deep red sub-pixel RA emits light alone, or the display red sub-pixel RB emits light alone.
[0115] The deep red sub-pixel RA and the display red sub-pixel RB are independent of each other. At the same time, at least one of the deep red sub-pixel RA and the display red sub-pixel RB can emit light. In some implementations, the deep red sub-pixel RA emits light, while the display red sub-pixel RB does not. In other implementations, the deep red sub-pixel RA and the display red sub-pixel RB emit light simultaneously. In still other implementations, the deep red sub-pixel RA does not emit light, while the display red sub-pixel RB emits light.
[0116] See also Figure 8 As shown, the deep red sub-pixel RA and the display red sub-pixel RB exist in the display panel 200 at the same time, so that the display panel 200 has an eye protection mode and a normal mode, which helps to reduce the power consumption of the display panel 200. When the display panel 200 is in normal mode, the light emitted by the display red sub-pixel RB, the green sub-pixel G and the blue sub-pixel B are mixed to form a pixel displaying an image. At this time, the deep red sub-pixel RA does not emit light, and the power consumption of the display panel 200 is low. When the display panel 200 is in eye protection mode, the deep red sub-pixel RA emits light. At this time, the deep red sub-pixel RA can illuminate the user's eyes and improve visual problems. When the display panel 200 is in normal mode and eye protection mode at the same time, the deep red sub-pixel RA and the display red sub-pixel RB emit light at the same time, which can improve visual problems while displaying the information to be displayed.
[0117] The peak wavelength of displayed red light is shorter than the peak wavelength of deep red light, resulting in a greater power consumption of the deep red sub-pixel RA than the red sub-pixel RB. This results in a lower power consumption when the display panel 200 is in normal mode than when it is in both eye protection mode and normal mode simultaneously. Customizing the operating time of eye protection mode helps extend the display time of the display panel 200 (when powered by a battery or other power source). Furthermore, by properly controlling the operating time of the deep red sub-pixel RA, the service life of the deep red sub-pixel RA can also be increased.
[0118] Compared to the issued Figure 7a The existing display panel of the spectrum diagram shown has Figure 8 When the deep red sub-pixel RA and the display red sub-pixel RB in the display panel 200 of the pixel array 10 emit light simultaneously, the color gamut coverage of the display panel 200 can also be improved, which helps to improve the color rendering capability of the display panel 200.
[0119] Figure 10 To contain Figure 8 Schematic diagram of the color gamut of the display panel with the pixel array shown and the existing display panel, Figure 11 To contain Figure 8 Spectral diagram of a display panel with the pixel array shown.
[0120] exist Figure 10 In the BT2020 color gamut, a1 refers to the BT2020 color gamut, and a2 refers to the BT2020 color gamut. Figure 4 The area of the BT2020 color gamut covered by the display panel of the pixel array shown, a3 refers to the area of the BT2020 color gamut covered by the existing display panel. Figure 7a 、 Figure 10 and Figure 11 It can be seen that the BT2020 color gamut coverage of the existing display panel is 72.16%, including Figure 8 The BT2020 color gamut coverage of the display panel 200 of the pixel array 10 shown is 74.14%, which helps to improve the color representation capability of the display panel 200.
[0121] For example, see Figure 8 As shown, multiple sub-pixels form multiple repeating units 11, and each repeating unit 11 is composed of a blue sub-pixel B, a green sub-pixel G, a deep red sub-pixel RA, and a display red sub-pixel RB. Specifically, the pixel array 10 is composed of multiple repeating units 11, and each repeating unit 11 is composed of four different color sub-pixels: blue sub-pixel B, green sub-pixel G, deep red sub-pixel RA, and display red sub-pixel RB.
[0122] It should be noted that, in addition to having a deep red sub-pixel RA in each repeating unit 11 in the display panel 200, in some implementations, the pixel array 10 includes multiple repeating units 11, each repeating unit 11 includes a blue sub-pixel B, a green sub-pixel G and a display red sub-pixel RB, and some of the multiple repeating units 11 also include a deep red sub-pixel RA.
[0123] When the pixel array 10 is composed of four different color sub-pixels, namely deep red photon pixel RA, display red photon pixel RB, green photon pixel G and blue photon pixel B, the pixel array 10 may include but is not limited to PenTile arrangement (diamond arrangement), Delta arrangement, Pearl arrangement (pearl arrangement), Triangular PenTile arrangement (Zhou Dongyu arrangement), hexagonal crystal pixel arrangement (honeycomb arrangement), tripod-shaped pixel arrangement, crystal diamond arrangement, etc.
[0124] For example, Figure 8 As shown, the deep red photon pixel RA, the display red photon pixel RB, the green photon pixel G and the blue photon pixel B form a diamond arrangement.
[0125] Specifically, see Figure 9 As shown, in each repeating unit 11, the deep red sub-pixels RA and the display red sub-pixels RB correspond one to one, and the corresponding deep red sub-pixels RA and display red sub-pixels RB constitute a red light image group. The arrangement of the red light image group, the green sub-pixels G, and the blue sub-pixels B is the same as the arrangement of the red pixels, green pixels, and blue pixels in the diamond arrangement. The red light image group is equivalent to the red pixel, and the position of the red light image group is the same as the position of the red pixel.
[0126] See also Figure 8 As shown, two adjacent repeating units 11 share one green sub-pixel G, two deep red sub-pixels RA, and two display red sub-pixels RB. In other words, two adjacent repeating units 11 share one green sub-pixel G and two red image groups. This improves the utilization of the green sub-pixels G, deep red sub-pixels RA, and display red sub-pixels RB, thereby increasing the density of the repeating unit 10.
[0127] For example, see Figure 9 As shown, each repeating unit 11 includes one blue sub-pixel B, four green sub-pixels G, and four red image groups. Along the circumference of the blue sub-pixel B, the four green sub-pixels G are spaced around the blue sub-pixel B, and the four red image groups are spaced around the blue sub-pixel B. The red image groups and the green sub-pixels G are arranged alternately.
[0128] It can be understood that the pixel array 10 includes multiple first pixel rows and multiple second pixel rows, the first pixel rows and the second pixel rows are alternately arranged along the first direction X, the first pixel rows include multiple red light sub-pixels and multiple green light sub-pixels G alternately arranged along the second direction Y, and the second pixel rows include multiple blue light sub-pixels B and multiple green light sub-pixels G alternately arranged along the second direction Y.
[0129] In each repeating unit 11, the number of deep red sub-pixels RA and the number of display red sub-pixels RB are the same. However, in some implementations, the number of deep red sub-pixels RA in each repeating unit 11 may be less than the number of display red sub-pixels RB. In other implementations, the number of deep red sub-pixels RA in each repeating unit 11 may be greater than the number of display red sub-pixels RB.
[0130] It can be seen from this that the number of deep red sub-pixels RA and display red sub-pixels RB in each repeating unit 11 can be the same or different, and both can enable the display panel 200 to have an eye protection mode and a normal mode, which can reduce the power consumption of the display panel 200 while providing an eye protection effect. However, when the deep red sub-pixels RA and the display red sub-pixels RB correspond one to one, the density of the deep red sub-pixels RA and the display red sub-pixels RB can be the same, which helps to increase the illumination range of the deep red light and ensure that the user's eyes receive the deep red light at all times. In addition, the sub-pixels can be arranged more regularly, which helps to improve the display effect of the display panel 200.
[0131] For example, Figure 9 As shown, the shape of the blue sub-pixel B is a square. However, the shape of the blue sub-pixel B may also be other shapes, such as a circle or an ellipse.
[0132] For example, Figure 9 As shown, the shape of the green sub-pixel G is a square. However, the shape of the green sub-pixel G may also be other shapes, such as a circle or an ellipse.
[0133] For example, Figure 9 As shown, the deep red photon pixel RA is in a square shape. However, the deep red photon pixel RA may also be in other shapes, such as a circle, a ring, or an ellipse.
[0134] For example, Figure 9 As shown, the shape of the red light display sub-pixel RB is a square. However, the shape of the red light display sub-pixel RB may also be other shapes, such as a circle, a ring, or an ellipse.
[0135] For example, the area of the blue sub-pixel B is larger than that of the red image group, which is larger than that of the green sub-pixel. The area of the red pixel is the sum of the areas of the corresponding deep red sub-pixel RA and the display red sub-pixel RB. Of course, the area relationship between the blue sub-pixel B, the green sub-pixel G, and the red image group can also be other relationships.
[0136] In some possible implementations, see Figure 8 and Figure 9 As shown, in each repeating unit 11, corresponding red light display sub-pixels RB and deep red light display sub-pixels RA are arranged at intervals.
[0137] In this way, the red sub-pixel RB and the deep red sub-pixel RA can emit light synchronously, or independently. At the same time, the display panel 200 can display the corresponding content. Furthermore, the difficulty of arranging the red sub-pixel RB and the deep red sub-pixel RA can be reduced, thereby reducing the difficulty of manufacturing the display panel 200.
[0138] In some possible implementations, in each repeating unit 11 , the ratio of the total area of the deep red sub-pixels RA to the total area of the display red sub-pixels RB is greater than or equal to 0.1 and less than or equal to 1. In this way, the power consumption and display effect of the display panel 200 can be effectively balanced.
[0139] For example, see Figure 9 As shown, the ratio of the total area of the deep red sub-pixels RA to the total area of the display red sub-pixels RB is equal to 1. Of course, the ratio of the total area of the deep red sub-pixels RA to the total area of the display red sub-pixels RB may also be less than 1, such as 0.1, 0.3, 0.5, 0.75, 0.8, etc.
[0140] Continue to see Figure 9 As shown, in each repeating unit 11, the deep red sub-pixels RA and the display red sub-pixels RB correspond one to one, and the areas of any two deep red sub-pixels RA are the same as the areas of any two display red sub-pixels RB. Therefore, the ratio of the area of the corresponding deep red sub-pixels RA to the area of the display red sub-pixels RB is greater than or equal to 0.1 and less than or equal to 1. For example Figure 9 As shown, the areas of the corresponding deep red sub-pixel RA and the display red sub-pixel RB are the same, or the areas of the corresponding deep red sub-pixel RA and the display red sub-pixel RB may also be different.
[0141] In some possible implementations, the energy ratio of the red sub-pixel RB, the green sub-pixel G, the blue sub-pixel B, and the deep red sub-pixel RA can be 0.5:1:1:1.4, which can obtain a target white point so that the display effect of the display panel 200 meets the requirements. The target white point refers to the target white point set according to the Rec.709 color standard, with the coordinates of the target white point in the 1931 CIE coordinate system being x=0.3127 and y=0.329, where x is the horizontal coordinate of the target white point and y is the vertical coordinate of the target white point.
[0142] For example, the currents supplied to the red, green, blue, and deep red sub-pixels RA can be controlled so that the energy ratio of the red, green, blue, and deep red sub-pixels RB, G, B, and RA is set to a preset ratio, for example, 0.5:1:1:1.4. It should be noted that other methods can also be used to control the energy ratio of the red, green, blue, and deep red sub-pixels RB, G, B, and RA to be set to a preset ratio.
[0143] It should be noted that when the coordinates of the target white point are other than "x = 0.3127, y = 0.329," the energy ratio of the red, green, blue, and deep red sub-pixels RB, G, B, and RA will change. In other words, when the energy ratios of the red, green, blue, and deep red sub-pixels RB, G, B, and RA are changed, the corresponding coordinate values of the target white point change, resulting in a corresponding display effect. For example, the energy ratio of the red, green, blue, and deep red sub-pixels RB, G, B, and RA can also be 0.6:1:1:1.5.
[0144] In the embodiment of the present application, there is no specific limitation on the relative positional relationship between the deep red sub-pixel RA and the display red sub-pixel RB in the pixel array 10. Several positional relationships between the deep red sub-pixel RA and the display red sub-pixel RB are described below.
[0145] In some possible implementations, see Figure 8 As shown, the pixel array 10 includes a plurality of first image groups, a plurality of second image groups, and a plurality of third image groups. The first image groups and the second image groups are arranged side by side and alternately along a first direction X. Each first image group includes a plurality of deep red sub-pixels RA arranged side by side and alternately along a second direction Y. Each second image group includes a plurality of display red sub-pixels RB arranged side by side and alternately along the second direction Y. A plurality of third image groups are arranged side by side and alternately along the second direction Y. Each third image group includes a plurality of deep red sub-pixels RA and a plurality of display red sub-pixels RB arranged side by side and alternately along the first direction X.
[0146] Figure 12 This is a schematic diagram of the architecture of the third pixel array provided in an embodiment of the present application. Figure 13 for Figure 12 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0147] In some other possible implementations, combined with Figure 12 and Figure 13 It can be seen that the pixel array 10 includes a plurality of first image groups, a plurality of second image groups, and a plurality of third image groups. The plurality of first image groups and the plurality of second image groups are arranged side by side and alternately along a first direction X. Each first image group includes a plurality of deep red sub-pixels RA arranged side by side and alternately along a second direction Y. Each second image group includes two first display image groups arranged side by side and alternately along the first direction X. Each first display image group includes a plurality of red display sub-pixels RB arranged side by side and alternately along the second direction Y. The plurality of third image groups are arranged side by side and alternately along the second direction Y. Each third image group includes a plurality of deep red sub-pixels RA arranged side by side and alternately along the first direction X, and a plurality of second display image groups. Each second display image group includes two red display sub-pixels RB arranged side by side and alternately along the first direction X.
[0148] Figure 14 This is a schematic diagram of the architecture of the fourth pixel array provided in an embodiment of the present application. Figure 15 for Figure 14 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0149] In some other possible implementations, combined with Figure 14 and Figure 15 As can be seen, the pixel array 10 includes a plurality of fourth image groups and a plurality of fifth image groups. The plurality of fourth image groups are arranged side by side and alternately along the first direction X, and the plurality of fifth image groups are arranged side by side and alternately along the second direction Y. Each fourth image group includes a plurality of deep red sub-pixels RA and a plurality of display red sub-pixels RB arranged side by side and alternately along the second direction Y. Each fifth image group includes a plurality of deep red sub-pixels RA and a plurality of display red sub-pixels RB arranged side by side and alternately along the first direction X.
[0150] It should be noted that when the corresponding deep red sub-pixels RA and display red sub-pixels RB are spaced apart, the arrangement of the deep red sub-pixels RA and display red sub-pixels RB may include but is not limited to: Figure 8 or Figure 13 The parallel arrangement shown, Figure 14 The staggered arrangement shown can also be other arrangements.
[0151] It should be noted that, in addition to being spaced apart, the corresponding deep red sub-pixels RA and display red sub-pixels RB may also be connected. The structure of the pixel array 10 when the corresponding deep red sub-pixels RA and display red sub-pixels RB are connected is described below.
[0152] Figure 16 This is a schematic diagram of the structure of the fifth pixel array provided in an embodiment of the present application. Figure 17 for Figure 16 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0153] Figure 16 and Figure 8 The difference is that in each repeating unit 11, the corresponding red light display sub-pixel RB and deep red light display sub-pixel RA are connected (eg Figure 14 In this way, the areas occupied by the corresponding red sub-pixels RB and deep red sub-pixels RA can be reduced, and the number of pixels of the display panel 200 can be increased when the area of the display panel 200 is constant.
[0154] It should be noted that Figure 13 The deep red sub-pixel RA, the display red sub-pixel RB, the green sub-pixel G, and the blue sub-pixel B in FIG are all square in shape. However, the shape of at least one of the deep red sub-pixel RA, the display red sub-pixel RB, the green sub-pixel G, and the blue sub-pixel B may also be other shapes. In addition, Figure 16 The arrangement of the deep red sub-pixel RA, the display red sub-pixel RB, the green sub-pixel G and the blue sub-pixel B may also be an arrangement of other pixel arrays 10 other than the diamond array.
[0155] Combine Figure 8 and Figure 16 It can be seen that Figure 16 The arrangement of deep red photon pixels RA and display red photon pixels RB is similar to Figure 8 The deep red sub-pixel RA and the display red sub-pixel RB are arranged in the same way, but Figure 16 The arrangement of deep red photon pixels RA and display red photon pixels RB can also be Figure 12 or Figure 14 The arrangement of the deep red sub-pixels RA and the display red sub-pixels RB in the pixel array 10 is shown, or other arrangements may be used.
[0156] In the above content, in each repeating unit 11, the corresponding deep red sub-pixel RA and the display red sub-pixel RB are arranged side by side, for example Figure 8 or Figure 16As shown, the corresponding deep red sub-pixel RA and the display red sub-pixel RB are arranged side by side along the first direction X. In this case, the corresponding deep red sub-pixel RA and the display red sub-pixel RB are connected or spaced apart. However, one of the deep red sub-pixel RA and the display red sub-pixel RB can also be arranged inside the other.
[0157] Figure 18 This is a schematic diagram of the structure of the sixth pixel array provided in an embodiment of the present application. Figure 19 for Figure 18 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0158] In some possible implementations, combined with Figure 18 and Figure 19 As can be seen, the pixel array 10 includes a plurality of repeating units 11 arranged along a first direction X and a second direction Y. In each repeating unit 11, the deep red sub-pixel RA is disposed within the corresponding display red sub-pixel RB. It is understood that the display red sub-pixel RB surrounds the corresponding deep red sub-pixel RA.
[0159] In this way, the red sub-pixel RB and the deep red sub-pixel RA can emit light synchronously, or can emit light independently. At the same time, the display panel 200 can also display corresponding content and implement an eye protection mode.
[0160] For example, Figure 19 As shown, the shape of the deep red photon pixel RA can be square, circular, or the like.
[0161] For example, Figure 19 As shown, the shape of the red sub-pixel RB can be a square ring structure, a circular ring structure, etc.
[0162] For example, Figure 19 As shown, the deep red sub-pixel RA is connected to the corresponding display red sub-pixel RB. However, the deep red sub-pixel RA and the corresponding display red sub-pixel RB can also be arranged at intervals, such as Figure 20 As shown. Among them, Figure 20 This is a schematic diagram of the structure of a repeating unit in the seventh pixel array provided in an embodiment of the present application.
[0163] Figure 21 This is a schematic diagram of the architecture of the eighth pixel array provided in an embodiment of the present application. Figure 22 for Figure 21 Schematic diagram of the architecture of a repeating unit in the pixel array shown.
[0164] In some other possible implementations, combined with Figure 21 and Figure 22As can be seen, the pixel array 10 includes a plurality of repeating units 11 arranged along a first direction X and a second direction Y. In each repeating unit 11, a red sub-pixel RB is disposed within a corresponding deep red sub-pixel RA. It is understood that the deep red sub-pixel RA surrounds the corresponding red sub-pixel RB.
[0165] In this way, the red sub-pixel RB and the deep red sub-pixel RA can emit light synchronously, or can emit light independently. At the same time, the display panel 200 can display corresponding content and implement an eye protection mode.
[0166] For example, Figure 22 As shown, the shape of the deep red photon pixel RA can be square, circular, or the like.
[0167] For example, Figure 22 As shown, the shape of the red sub-pixel RB can be a square ring structure, a circular ring structure, etc.
[0168] For example, Figure 22 As shown, the deep red sub-pixel RA is connected to the corresponding display red sub-pixel RB. However, the deep red sub-pixel RA and the corresponding display red sub-pixel RB can also be arranged at intervals.
[0169] In the above description, in each repeating unit 11, the corresponding deep red sub-pixel RA and display red sub-pixel RB constitute a red light image group, and the red light image group is arranged with the green sub-pixel G and the blue sub-pixel B in a corresponding arrangement, such as a PenTile arrangement (diamond arrangement), a Delta arrangement, a Pearl arrangement (pearl arrangement), a Triangular PenTile arrangement (Zhou Dongyu arrangement), a hexagonal crystal pixel arrangement (honeycomb arrangement), a tripod pixel arrangement, a crystal diamond arrangement, etc. However, the deep red sub-pixel RA and display red sub-pixel RB can also be arranged as a whole with the green sub-pixel G and the blue sub-pixel B in a corresponding arrangement.
[0170] For example, Figure 23 and Figure 8 The difference is that the shapes of the deep red sub-pixel RA, the display red sub-pixel RB, the green sub-pixel G and the blue sub-pixel B are all different, and the position of the deep red sub-pixel RA is different. Specifically, Figure 23 The arrangement of the red sub-pixel RB, green sub-pixel G and blue sub-pixel B in the display is the same as Figure 8 The arrangement of the red sub-pixel RB, green sub-pixel G and blue sub-pixel B is the same. Figure 23 The deep red photon pixel RA in Figure 8 The arrangement of the deep red photon pixels RA is different.
[0171] like Figure 23 As shown, the pixel array 10 includes a first array and a second array. The red sub-pixels RB, green sub-pixels G, and blue sub-pixels B may form a first array similar to a diamond arrangement. The plurality of deep red sub-pixels RA may form a second array.
[0172] It should be noted that the first array composed of red sub-pixels RB, green sub-pixels G and blue sub-pixels B is not limited to the diamond arrangement, but can also be a Delta arrangement, Pearl arrangement (pearl arrangement), Triangular PenTile arrangement (Zhou Dongyu arrangement), hexagonal crystal pixel arrangement (honeycomb arrangement), tripod pixel arrangement, crystal diamond arrangement and other arrays. Figure 23 The positions of the deep red sub-pixels RA and the display red sub-pixels RB are swapped, that is, the deep red sub-pixels RA, the green sub-pixels G and the blue sub-pixels B form a first array, and the multiple display red sub-pixels RB form a second array.
[0173] For example, see Figure 24 As shown, each repeating unit 11 includes one blue sub-pixel B, four green sub-pixels G, four deep red sub-pixels RA, and four display red sub-pixels RB. Along the circumference of the blue sub-pixel B, the four green sub-pixels G, four deep red sub-pixels RA, and four display red sub-pixels RB are arranged at intervals around the blue sub-pixel B. The four display red sub-pixels RB and the four green sub-pixels G are arranged alternately, and the four green sub-pixels G and the four deep red sub-pixels RA are arranged alternately. The centers of the four green sub-pixels G form a virtual quadrilateral surrounding the blue sub-pixel B. The centers of the four deep red sub-pixels RA form a virtual quadrilateral surrounding the blue sub-pixel B. The centers of the four display red sub-pixels RB form a virtual quadrilateral surrounding the blue sub-pixel B. The centers of the four display red sub-pixels RB form a virtual quadrilateral surrounding the blue sub-pixel B, the green sub-pixels G, and the deep red sub-pixels RA.
[0174] Understandably, see Figure 24 As shown, each repeating unit 11 includes four repeating sub-units 12. Each repeating sub-unit 12 includes a red display sub-pixel RB, a deep red sub-pixel RA, a blue sub-pixel B, and two green sub-pixels G. Two adjacent repeating sub-units 12 share a green sub-pixel G, and four repeating sub-units 12 share a blue sub-pixel B. The four repeating sub-units 12 are arranged along the circumference of the blue sub-pixel B. In each repeating sub-unit 12, the centers of the two green sub-pixels G, the center of the blue sub-pixel B, and the center of the red display sub-pixel RB form a virtual quadrilateral surrounding the deep red sub-pixel RA. The two sub-pixels corresponding to any side of the virtual quadrilateral are configured to emit light of different colors.
[0175] For example, Figure 24 As shown, the shape of the blue sub-pixel B is an ellipse. However, the shape of the blue sub-pixel B may also be other shapes, such as a circle or a square.
[0176] For example, Figure 24 As shown, the shape of the green sub-pixel G is circular. However, the shape of the green sub-pixel G may also be other shapes, such as square or elliptical.
[0177] For example, Figure 24 As shown, the shape of the deep red photon pixel RA is circular. However, the shape of the deep red photon pixel RA may also be other shapes, such as square, ring, or ellipse.
[0178] For example, Figure 24 As shown, the shape of the red light display sub-pixel RB is circular. However, the shape of the red light display sub-pixel RB may also be other shapes, such as square or elliptical.
[0179] In the description of the embodiments of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on specific circumstances.
