Description

Technical Field

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

[0002] The backlight power saving technology of LCD screens mainly adds photosensitive elements to the backlight module. The photosensitive elements detect the brightness of the ambient light to adjust the backlight brightness in real time. However, this will not only take up space in the entire machine, but also reduce the screen-to-body ratio of the display. In addition, the photosensitive elements in the backlight module need to add an IC chip with light sensing function, resulting in higher product costs. Therefore, most panel manufacturers currently try to integrate photosensitive elements directly into the panel, using thin film transistors (TFT) as photosensitive elements, and using the difference in characteristics of TFT before and after being exposed to light to monitor the size of its leakage current to feedback the brightness of the ambient light, thereby adjusting the backlight brightness.

[0003] Since the light wave components of ambient light are complex, including visible light and invisible light such as infrared light and ultraviolet light, for ambient light sensors, light waves with a wavelength of 380-780 nanometers are the effective light waves they hope to use. Ultraviolet light and infrared light with wavelengths outside of 380-780 nanometers will cause the sensitivity of the light sensor to decrease, affecting the accuracy of the light sensor's detection.

DETAILED DESCRIPTION

[0018] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative, but the present application can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0019] In addition, unless otherwise clearly specified or limited, "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internally connected between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0020] Figure 1 is a partial schematic diagram of a display panel provided in an embodiment of the present application, such as Figure 1 As shown, the display panel 20 includes a display substrate 100, a light sensor 500, a scattering prism 600 and a focusing unit 700. The light sensor 500 is arranged on the display substrate 100 to sense ambient light; the scattering prism 600 is arranged on a side of the light sensor 500 away from the display substrate 100 to disperse the ambient light into light of different wavelengths; the focusing unit 700 is arranged between the light sensor 500 and the scattering prism 600 to focus the visible light dispersed by the scattering prism 600 onto the light sensor 500.

[0021] In the embodiment of the present application, a light sensor 500 is integrated into the display panel 20, and a scattering prism 600 and a focusing unit 700 are added to the light sensor 500. The scattering prism 600 is used to disperse the ambient light into light of different wavelengths, and then the focusing unit 700 is used to focus the scattered visible light into white light. At this time, the white light does not contain invisible light such as infrared light and ultraviolet light. After the re-focused white light is focused on the light sensor 500, the light sensor 500 receives only visible light without invisible light, thereby avoiding the influence of invisible light such as infrared light and ultraviolet light in the ambient light on the detection of the light sensor 500, thereby improving the accuracy of the light sensor 500.

[0022] Specifically, the dispersion prism 600 can be a triangular prism, or a four-sided prism or other dispersion prisms. Taking a triangular prism as an example, the triangular prism has a spectroscopic property that can disperse ambient light into light of different wavelengths. When light enters the triangular prism, it will first undergo a first refraction, and then refract out at different angles; among them, since red light has a larger wavelength, the refraction angle is smaller; the wavelength of blue light is relatively small, and the refraction angle is larger. Therefore, light of different wavelengths will be dispersed into a spectrum, which includes visible light such as red, orange, yellow, green, blue, indigo and violet, as well as invisible light with a wavelength greater than red light and invisible light with a wavelength less than violet light.

[0023] The function of the light focusing unit 700 is to focus light, and can focus the visible light dispersed by the dispersion prism 600, and then irradiate it to the light sensor 500. It should be understood that the invisible light dispersed by the dispersion prism 600 is either blocked, reflected, or dispersed to an area outside the light focusing unit 700, so that the invisible light cannot be irradiated on the light focusing unit 700, but it does not mean that the light focusing unit 700 cannot focus the invisible light.

[0024] During product design, the size and angle of the dispersion prism 600, as well as the distances among the light sensor 500, the dispersion prism 600 and the focusing unit 700 are adjusted through experiments, so that the ambient light is dispersed into lights of different wavelengths after being irradiated by the dispersion prism 600, and the visible light therein is then focused by the focusing unit 700 onto the light sensor 500, so that the light sensor 500 only receives the visible light in the ambient light.

[0025] like Figure 2 As shown, as a further embodiment, the display panel 20 further includes a lens 800 , and the lens 800 is disposed on a side of the dispersion prism 600 away from the focusing unit 700 . The lens 800 is a focusing lens for focusing ambient light onto the dispersion prism 600 .

[0026] Figure 3 It is a schematic diagram of the optical path of a convex lens, such as Figure 3 As shown, the focal length of the convex lens is f'=nr1r2 / (n-1)[n(r2-r1)+(n-1)d], where n is the refractive index of the convex lens material, d is the center thickness of the lens 800, r1 and r2 are the curvature radii of the two surfaces of the convex lens, r1 is a positive value, and r2 is a negative value. Therefore, for a convex lens with a fixed refractive index, the smaller the radius of curvature, the larger d is, and the smaller the focal length is; conversely, the larger the radius of curvature, the smaller d is, and the larger the focal length is.

[0027] By adopting the design of combining lens 800 with dispersion prism 600, the smaller the focal length of lens 800, the smaller the distance between lens 800 and dispersion prism 600, and vice versa. Therefore, by adjusting the height of lens 800, the focus of lens 800 can be placed on the surface of dispersion prism 600, thereby dispersing light into lights of different wavelengths.

[0028] This embodiment adds a lens 800, which can gather all the ambient light directly above the dispersion prism 600 to a point or a small area in the dispersion prism 600, so that all the ambient light is refracted at this point, and finally the light coming out of the dispersion prism 600 appears in the same spectrum, so that the light of the same wavelength passing through the dispersion prism 600 is gathered together, and it is easier to filter and shield invisible light, as well as to gather visible light, and it can also improve the light gathering effect and brightness. It avoids the problem of spectrum deviation of the light coming out of the dispersion prism 600 due to the difference in refraction position and angle after the ambient light enters from different positions of the dispersion prism 600.

[0029] Furthermore, the surface area of ​​the lens 800 is larger than the surface area of ​​the dispersion prism 600, that is, the orthographic projection of the lens 800 on the display substrate 100 covers the orthographic projection of the dispersion prism 600 on the display substrate 100, and the orthographic projection area of ​​the lens 800 on the display substrate 100 is larger than the orthographic projection area of ​​the dispersion prism 600 on the display substrate 100. Through this design, the lens 800 can gather more ambient light and increase the amount of light gathered on the light sensor 500 to compensate for the filtering and weakening of ambient light by the dispersion prism 600, the focusing unit 700 and other film layers in the display panel 20, thereby improving the detection accuracy of the light sensor 500.

[0030] In the embodiments of the present application, Figure 4 As shown, the display panel 20 also includes a shading unit 900, which is arranged on the side of the dispersion prism 600 facing the focusing unit 700, and the shading unit 900 is used to block the invisible light dispersed by the dispersion prism 600; the shading unit 900 includes a first block 910 and a second block 920, and the first block 910 and the second block 920 are respectively arranged at the two ends of the side of the dispersion prism 600 facing the focusing unit 700.

[0031] like Figure 5As shown, after the ambient light passes through the dispersion prism 600, it will be dispersed into a spectrum consisting of visible light such as red, orange, yellow, green, blue, indigo, and purple, as well as invisible light such as infrared and ultraviolet, wherein the invisible light with a wavelength greater than the red light is greater than the outside of the red light, and the invisible light with a wavelength less than the purple light is located outside the purple light. The shading unit 900 is used to block the invisible light. Since there is invisible light with a wavelength greater than the visible light and invisible light with a wavelength less than the visible light, the embodiment of the present application sets a first block 910 and a second block 920 at both ends of the side of the dispersion prism 600 facing the focusing unit 700, respectively, and uses the first block 910 to block the invisible light with a wavelength less than the visible light, and uses the second block 920 to block the invisible light with a wavelength greater than the visible light, thereby achieving the purpose of blocking different types of invisible light.

[0032] As for the specific position design and specific size design of the first block 910 and the second block 920, during the design stage, the corresponding design can be made by simulating the position of the non-visible light in the ambient light after passing through the dispersion lens 800 and coming out from the dispersion prism 600 toward the side of the focusing unit 700. The position of the first block 910 and the second block 920 can also be adjusted by measuring the wavelength of the light passing through the dispersion prism 600 through an optical instrument. Moreover, corresponding simulations can also be performed for the two situations of whether there is a lens 800 above the dispersion prism 600.

[0033] Specifically, the shading unit 900 is a black coating coated on the surface of the dispersion prism 600 , for example, black ink or other black materials are coated on the surface of the dispersion prism 600 .

[0034] Of course, other dark coatings may be applied to the surface of the dispersion prism 600, or dark tapes, dark blocks or other light-blocking structures may be attached to the surface of the dispersion prism 600. Alternatively, instead of setting the light shielding unit 900 on the side of the dispersion prism 600 facing the light focusing unit 700, a reflection unit, a filtering unit or other shielding structure may be set to reflect or filter the non-visible light, as long as it is possible to prevent the non-visible light such as ultraviolet light and infrared light from irradiating the light sensor 500.

[0035] Of course, in other embodiments, the display panel 20 may also not have the shading unit 900. By adjusting the size or distance between the dispersion prism 600 and the focusing unit 700, for example, reducing the size of the focusing unit 700, the focusing unit 700 can only receive the visible light dispersed by the dispersion prism 600, while the invisible light dispersed by the dispersion prism 600 will not be irradiated onto the focusing unit 700.

[0036] In a specific design, the dispersion degree of the dispersion prism 600 can be increased by selecting a material with a high refractive index to make the dispersion prism 600 or increasing the size of the top angle of the dispersion prism 600, so that the shading unit 900 can better shield infrared light and ultraviolet light and reduce the impact of these invisible lights on the light sensor 500.

[0037] As an optional implementation, Figure 1 As shown, the light focusing unit 700 is a convex lens, which uses the light focusing principle of the convex lens to focus the visible light dispersed by the dispersion prism 600 onto the light sensor 500. Since the convex lens can make the light concentration higher, the use of this embodiment can improve the light focusing effect.

[0038] As another optional implementation, Figure 6 As shown, the light focusing unit 700 is a prism, which uses the refraction principle of the prism to focus the visible light dispersed by the dispersion prism 600 onto the light sensor 500. The prism adopts the same design as the dispersion prism 600, and can be a triangular prism. By adjusting the position of the prism, the light is dispersed by the dispersion prism 600 and then focused by the light focusing unit 700, and the state of the dispersed light after passing through the light focusing unit 700 is similar to the state of the light before entering the dispersion prism 600 and removing the non-visible light.

[0039] In the embodiment of the present application, the display panel 20 may be a liquid crystal display (LCD) display panel, or an organic light-emitting semiconductor (OLED) display panel or other types of display panels. When the display panel 20 is a liquid crystal display panel, the display substrate 100 is an array substrate, and the display panel 20 further includes a color filter substrate 200 and a liquid crystal layer. The display substrate 100 and the color filter substrate 200 are arranged in a box, and the liquid crystal layer is arranged between the display substrate 100 and the color filter substrate 200. When the display panel 20 is an organic light-emitting semiconductor display panel, the display panel 20 further includes an encapsulation layer, which is arranged on the display substrate 100 and is used to encapsulate the devices on the display substrate 100.

[0040] like Figure 7As shown, as a specific implementation, the display panel 20 is a liquid crystal display panel, the display substrate 100 is an array substrate, the display panel 20 further includes a color filter substrate 200, an optical adhesive layer 300 and a cover plate 400, the color filter substrate 200 and the display substrate 100 are arranged in a box, the light sensor 500 is arranged on the side of the display substrate 100 facing the color filter substrate 200, the light sensor 500 can adopt a (Thin Film Transistor) structure, and can be formed through the same process as the active switch on the display substrate 100, so as to reduce the production cost of the light sensor 500 and improve the production efficiency of the display panel 20.

[0041] Of course, in other implementations, the light sensor 500 may be a diode photoelectric structure manufactured on the display substrate 100 , or a chip structure attached to the display substrate 100 .

[0042] The cover plate 400 is arranged on a side of the color film substrate 200 away from the display substrate 100, and the cover plate 400 and the color film substrate 200 are bonded by the optical adhesive layer 300; the dispersion prism 600 is arranged in the optical adhesive layer 300, and the dispersion prism 600 can be filled in the optical adhesive layer 300 before it is cured, and then the cover plate 400 is covered. The dispersion prism 600 can be a three-prism right-angle lens, and one right-angle surface of the three-prism right-angle lens is arranged parallel to the color film substrate 200 and attached to the surface of the color film substrate 200 to improve the stability of the dispersion prism 600, and prevent the dispersion prism 600 from deviating in angle due to its own gravity or the movement of the display panel 20 during the curing process of the optical adhesive layer 300, thereby affecting the light dispersion angle and finally affecting the detection effect of the light sensor 500.

[0043] The light-collecting unit 700 and the light-shielding unit 900 are disposed on the color film substrate 200. The light-shielding unit 900 is disposed in the non-display area of ​​the color film substrate 200, and the light sensor 500 is disposed in the non-display area of ​​the display substrate 100. The light-shielding unit 900 is a black matrix structure originally in the non-display area on the color film substrate 200, and is used to prevent light leakage in the non-display area. In this embodiment, a hole 930 is opened in the black matrix structure, so that the orthographic projections of the light-collecting unit 700 and the light sensor 500 on the display substrate 100 are located within the orthographic projection range of the opening 930 on the display substrate 100.

[0044] Furthermore, the orthographic projection of the middle area of ​​the scattering prism 600 on the display substrate 100 is located within the orthographic projection range of the opening 930 on the display substrate 100, and the orthographic projections of both ends of the scattering prism 600 on the display substrate 100 are located outside the orthographic projection range of the opening 930 on the display substrate 100, so as to utilize the shading unit 900 to block the invisible light dispersed by the scattering prism 600.

[0045] In this embodiment, the lens 800 is formed by partially grinding the cover plate 400, and the focusing unit 700 is formed by partially grinding the substrate in the color film substrate 200, that is, only the position where the lens 800 is set in the cover plate 400 and the position where the focusing unit 700 is set in the substrate in the color film substrate 200 are ground to form a convex lens shape with a curved surface to achieve a focusing effect.

[0046] In this embodiment, the cover plate 400 and the substrate in the color film substrate 200 are made of transparent glass to ensure high transparency. By setting the lens 800 in the cover plate 400 and setting the focusing unit 700 in the substrate in the color film substrate 200, the thickness of the display panel 20 is prevented from increasing due to the added lens 800 and the focusing unit 700.

[0047] The light shielding unit 900 is disposed on the side of the color filter substrate 200 facing the cover plate 400, so as to be located between the light focusing unit 700 and the dispersion prism 600. This embodiment utilizes the original structure of the display panel 20 as the shielding unit, which saves the manufacturing process of the display panel 20 and avoids increasing the thickness of the display panel 20.

[0048] Of course, in other embodiments, the focusing unit 700 can also be bonded to the color filter substrate 200 by optical glue, and the lens 800 can also be bonded to the cover plate 400 by optical glue. At the same time, the positions of the dispersion prism 600, the lens 800 and the focusing unit 700 in the display panel 20 can also be adjusted.

[0049] In other embodiments, a light-transmitting hole may be provided on the display panel 20, a cylindrical structure may be inserted into the light-transmitting hole, and a lens 800, a dispersion prism 600, and a light-collecting unit 700 may be provided in the cylindrical structure. In this embodiment, the design of the cylindrical structure and the internal lens 800, the dispersion prism 600, and the light-collecting unit 700 may be completed independently, so that the lens 800, the dispersion prism 600, and the light-collecting unit 700 may be adjusted conveniently during the design stage.

[0050] like Figure 8As shown, the embodiment of the present application further provides a display device, the display device 10 includes a driving circuit 30 and the display panel 20 described above, the driving circuit 30 is used to drive the display panel 20. The driving circuit 30 is connected to the light sensor 500 and the data line in the display panel 20 at the same time, the light sensor 500 outputs a photocurrent corresponding to the ambient light, and the driving circuit 30 adjusts the current output to the data line in the display panel 20 according to the photocurrent output by the light sensor 500, thereby adjusting the display brightness of the display panel 20, thereby achieving a design of regulating the brightness of the display panel 20 according to the ambient light.

[0051] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
