Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a display device having the display panel. Background Technology

[0002] Liquid crystal displays (LCDs) are widely used in the display field due to their advantages such as thin body, low power consumption, no radiation, and soft image.

[0003] A liquid crystal display device includes a backlight module and a display panel. The backlight module provides backlight to the display panel, which displays the image. Most of the light emitted by the display panel is perpendicular to the viewpoint. Therefore, light emitted from the normal viewing angle of the display panel will not exhibit color shift. However, light emitted from the oblique viewing angle (wide viewing angle) of the display panel will show color shift, resulting in a color distortion when viewed from the oblique viewing angle. In some cases, users may only see pure white or pure black from the oblique viewing angle.

[0004] Therefore, how to solve the color shift of light emitted from the oblique viewing angle of the display panel in the prior art is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a display panel and a display device having the display panel, which aims to solve the problem in the prior art that the color shift of the light emitted from the oblique viewing angle of the display panel causes the user to see a color shift in the image displayed on the display panel from the oblique viewing angle.

[0006] To address the aforementioned technical problems, this application provides a display panel disposed on the light-emitting side of a backlight module, with the backlight module providing backlight to the display panel. The display panel includes a first substrate assembly, a liquid crystal layer, and a second substrate assembly stacked on one side of the backlight module. The first substrate assembly includes a plurality of color resists spaced apart, and the second substrate assembly includes a light-shielding layer and a plurality of reflective elements. The light-shielding layer has a plurality of light-transmitting holes, each corresponding to a color resist. A reflective element is disposed on the inner wall of one of the light-transmitting holes. The plurality of color resists includes a plurality of first color resists, a plurality of second color resists, and a plurality of third color resists, which are sequentially spaced apart. The first color resists convert the backlight into a first color light, the second color resists convert the backlight into a second color light, and the third color resists convert the backlight into a third color light. The reflective elements reflect the first, second, and third color lights to the oblique viewing angle of the display panel.

[0007] In summary, the display panel provided in this application embodiment reflects the first color light, the second color light, and the third color light to the oblique viewing angle direction of the display panel through the reflective element, thereby avoiding color shift of the light emitted from the oblique viewing angle direction of the display panel.

[0008] In an exemplary embodiment, the inner wall of the light-transmitting hole is inclined inward in the direction opposite to the liquid crystal layer of the second substrate assembly.

[0009] In an exemplary embodiment, the angle between the reflective element and the frontal viewing direction of the display panel is 45 degrees to 60 degrees.

[0010] In an exemplary embodiment, the position of one of the reflective elements corresponds to the periphery of one of the first color resists, the position of one of the reflective elements corresponds to the periphery of one of the second color resists, and the position of one of the reflective elements corresponds to the periphery of one of the third color resists.

[0011] In an exemplary embodiment, the thickness of the light-shielding layer is the same as the thickness of the reflective element.

[0012] In an exemplary embodiment, the first substrate assembly further includes a first substrate, a driving circuit layer, an encapsulation layer, and a plurality of pixel electrodes. The driving circuit layer is disposed on the side of the first substrate facing the liquid crystal layer, and the encapsulation layer covers the first color resist, the second color resist, and the third color resist to the side of the driving circuit layer opposite to the first substrate. The plurality of pixel electrodes are disposed on the side of the encapsulation layer opposite to the driving circuit layer, and the position of one pixel electrode corresponds to the position of one color resist.

[0013] In an exemplary embodiment, the encapsulation layer has a plurality of vias penetrating the encapsulation layer, with one via located adjacent to one of the color resists, and the driving circuit layer exposed in each via. The first substrate assembly also includes a plurality of connection electrodes, one of which is disposed within one of the vias, with its opposite ends connected to the driving circuit layer and the pixel electrode, respectively, and the driving circuit layer electrically connected to each of the pixel electrodes.

[0014] In an exemplary embodiment, the second substrate assembly further includes a second substrate and a common electrode. The light-shielding layer is disposed on the side of the second substrate facing the liquid crystal layer, and the common electrode is disposed on the side of the light-shielding layer facing away from the second substrate, covering each of the reflective elements. The liquid crystal layer is located between the common electrode and the pixel electrode.

[0015] In an exemplary embodiment, the display panel further includes a lower polarizer and an upper polarizer, the lower polarizer being disposed on the side of the first substrate assembly facing away from the liquid crystal layer, and the upper polarizer being disposed on the side of the second substrate assembly facing away from the liquid crystal layer.

[0016] Based on the same concept, this application also provides a display device, which includes a backlight module and the aforementioned display panel, wherein the display panel is disposed on the light-emitting side of the backlight module.

[0017] In summary, the display device provided in this application includes a backlight module and a display panel. The display panel reflects the first color light, the second color light and the third color light to the oblique viewing angle direction of the display panel through the reflective element, thereby avoiding color shift of the light emitted from the oblique viewing angle direction of the display panel.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the layer structure of the display device disclosed in the first embodiment of this application. The display device 1 can be used in electronic devices including but not limited to televisions, tablet computers, laptops, desktop computers, mobile phones, and vehicle displays.

[0034] The display device 1 includes a display panel 10 and a backlight module 30 stacked together. The display panel 10 is disposed on the light-emitting side of the backlight module 30 and is used to display images under the backlight provided by the backlight module 30.

[0035] In the embodiments of this application, Figure 1 The backlight module 30 shown can be an edge-lit backlight module, or it can be a direct-lit backlight module. The display panel 10 can be a Twisted Nematic (TN) display panel, a Vertical Alignment (VA) display panel, an In-Plane Switching (IPS) display panel, or a Fringe Field Switching (FFS) display panel; this application does not impose specific limitations on this.

[0036] In an exemplary embodiment, the display device 1 may also include other necessary components and parts such as a driver board, a power board, a high-voltage board, and a button control board.

[0040] Please see Figure 2 , Figure 2 This is a schematic diagram of the layer structure of the display panel disclosed in the second embodiment of this application. For ease of description, the following definitions are used. Figure 2 The length direction of the display panel 10 shown is the X-axis direction, the width direction of the display panel 10 is the Y-axis direction, and the thickness direction of the display panel 10 is the Z-axis direction. The X-axis direction, Y-axis direction and Z-axis direction are perpendicular to each other.

[0041] In this embodiment, the display panel 10 includes a lower polarizer 11, a first substrate assembly 12, a liquid crystal layer 13, a second substrate assembly 14, and an upper polarizer 15, which are sequentially stacked along the Z-axis. That is, the lower polarizer 11 is disposed on the light-emitting side of the backlight module 30, the first substrate assembly 12 is disposed along the Z-axis on the side of the lower polarizer 11 opposite to the backlight module 30, the liquid crystal layer 13 is disposed on the side of the first substrate assembly 12 opposite to the lower polarizer 11, the second substrate assembly 14 is disposed on the side of the liquid crystal layer 13 opposite to the first substrate assembly 12, and the upper polarizer 15 is disposed on the side of the second substrate assembly 14 opposite to the liquid crystal layer 13. The backlight provided by the backlight module 30 passes sequentially through the lower polarizer 11, the first substrate assembly 12, the liquid crystal layer 13, the second substrate assembly 14, and the upper polarizer 15. The lower polarizer 11 and the upper polarizer 15 are used to convert the backlight of natural light into the backlight of polarized light. The first substrate assembly 12 and the second substrate assembly 14 are used to form a preset electric field. The preset electric field is used to drive the liquid crystal molecules in the liquid crystal layer 13 to deflect, thereby changing the transmittance of the liquid crystal layer 13, so that the display panel 10 displays different grayscale brightness.

[0042] Specifically, the first substrate assembly 12 includes a first substrate 121, a driving circuit layer 122, a plurality of color resists 123, an encapsulation layer 124, and a plurality of pixel electrodes 125. The first substrate 121 is disposed on the side of the lower polarizer 11 facing the upper polarizer 15. The driving circuit layer 122 is disposed on the side of the first substrate 121 opposite to the lower polarizer 11. The plurality of color resists 123 are disposed on the side of the driving circuit layer 122 opposite to the first substrate 121, and are arranged in an array and spaced apart from each other. The encapsulation layer 124 is disposed on the side of the driving circuit layer 122 opposite to the first substrate 121 and covers each color resist 123; that is, the encapsulation layer 124 covers each color resist 123 to the driving circuit layer 122. The encapsulation layer 124 has multiple vias (not shown) penetrating through it. Each via is adjacent to a color resist 123, and the driving circuit layer 122 exposes each via. The first substrate assembly also includes multiple connection electrodes (not shown). Each connection electrode is disposed within a via, with one end connected to the driving circuit layer 122, and the connection electrode is electrically connected to the driving circuit layer 122. Multiple pixel electrodes 125 are disposed on the side of the encapsulation layer 124 opposite to the driving circuit layer 122. Each pixel electrode 125 corresponds to a color resist 123, meaning the orthographic projection of a pixel electrode 125 in the Z-axis direction coincides with the orthographic projection of a color resist 123 in the Z-axis direction. The pixel electrode 125 is connected to the end of the connection electrode opposite to the driving circuit layer 122, and the pixel electrode 125 is electrically connected to the driving circuit layer 122 through the connection electrode. The driving circuit layer 122 is used to output electrical signals to each pixel electrode 125 to control the potential of each pixel electrode 125. The encapsulation layer 124 is used to block impurities such as air, moisture or dust, and to prevent each color resist 123 and the driving circuit layer 122 from coming into contact with impurities such as air, moisture or dust.

[0043] In this embodiment, the driving circuit layer 122 controls the potential of each pixel electrode 125 through active matrix (AM) driving. Active matrix driving means that the driving circuit layer 122 equips each pixel electrode 125 with a thin-film transistor with switching function and a capacitor for storing charge.

[0044] Please see Figure 2The plurality of color resists 123 include a plurality of first color resists 123a, a plurality of second color resists 123b, and a plurality of third color resists 123c. The plurality of first color resists 123a, the plurality of second color resists 123b, and the plurality of third color resists 123c are arranged alternately along the X-axis. That is, the plurality of first color resists 123a, the plurality of second color resists 123b, and the plurality of third color resists 123c can be arranged in the X-axis direction in the following order: first color resist 123a, second color resist 123b, third color resist 123c, first color resist 123a, second color resist 123b, third color resist 123c, ..., first color resist 123a, second color resist 123b, third color resist 123c. The first color resist 123a is used to convert the backlight emitted by the backlight module 30 into a first color light, the second color resist 123b is used to convert the backlight emitted by the backlight module 30 into a second color light, and the third color resist 123c is used to convert the backlight emitted by the backlight module 30 into a third color light. The first color light can be red light, the second color light can be green light, and the third color light can be blue light, so that the display panel 10 displays in color.

[0045] The second substrate assembly 14 includes a second substrate 141, a light-shielding layer 142, a plurality of reflective elements 143, and a common electrode 144. The second substrate 141 is disposed on the side of the upper polarizer 15 facing the lower polarizer 11. The light-shielding layer 142 is disposed on the side of the second substrate 141 facing away from the upper polarizer 15. The light-shielding layer 142 has a plurality of light-transmitting holes 142a penetrating through it. The plurality of light-transmitting holes 142a are arranged in an array, and the position of one light-transmitting hole 142a corresponds to the position of one color resist 123, that is, the orthographic projection of one light-transmitting hole 142a in the Z-axis direction coincides with the orthographic projection of one color resist 123 in the Z-axis direction. A reflective element 143 is disposed on the inner wall of each light-transmitting hole 142a. The common electrode 144 is disposed on the side of the light-shielding layer 142 opposite to the second substrate 141, and covers each of the reflective elements 143 and the portion of the second substrate 141 exposed by each of the light-transmitting holes 142a. The liquid crystal layer 13 is located between the common electrode 144 and the pixel electrode 125. A preset electric field is formed between the common electrode 144 and the pixel electrode 125 to drive the deflection of liquid crystal molecules.

[0046] Figure 2 The dashed arrows shown represent the propagation path of the first color light. For the propagation paths of the second and third colors of light, please refer to the propagation path of the first color light. Figure 2The example is not repeated here. A portion of the first color light passes through the light-transmitting hole 142a corresponding to the position of the first color resist 123a and is incident on the reflective element 143 located on the inner wall of the light-transmitting hole 142a. The reflective element 143 reflects the first color light to the display panel 10 at an oblique viewing angle. A portion of the second color light passes through the light-transmitting hole 142a corresponding to the position of the second color resist 123b and is incident on the reflective element 143 located on the inner wall of the light-transmitting hole 142a. The reflective element 143 reflects the second color light to the display panel 10 at an oblique viewing angle. A portion of the third color light passes through the light-transmitting hole 142a corresponding to the position of the third color resist 123c and is incident on the reflective element 143 located on the inner wall of the light-transmitting hole 142a. The reflective element 143 reflects the third color light to the display panel 10 at an oblique viewing angle. The light-shielding layer 142 is used to block the first color light, the second color light and the third color light to prevent the first color light, the second color light and the third color light from mixing.

[0047] Understandably, most of the first, second, and third colored light that passes directly through the light-transmitting hole 142a are parallel to the normal viewing angle of the display panel 10. Therefore, the image displayed on the display panel 10 will not show color shift when viewed from the normal viewing angle. The reflective element 143 reflects the first, second, and third colored light to the oblique viewing angle (wide viewing angle) direction of the display panel 10, so that the image displayed on the display panel 10 will not show color shift when viewed from the oblique viewing angle (wide viewing angle), thus improving the display quality of the display panel 10.

[0048] In this embodiment of the application, the size of the inner wall of the light-transmitting hole 142a gradually decreases in the Z-axis direction. That is, Figure 2 The cross-section of the light-transmitting hole 142a shown can be trapezoidal. In the direction of the second substrate assembly 14 away from the liquid crystal layer 13, the inner wall of the light-transmitting hole 142a is inclined inwards. The opening size of the light-transmitting hole 142a on the side closer to the liquid crystal layer 13 is larger than the opening size on the side farther from the liquid crystal layer 13. That is, the inner wall of the light-transmitting hole 142a is inclined relative to the Z-axis direction, causing the reflective element 143 located on the inner wall of the light-transmitting hole 142a to also be inclined. Consequently, the reflective surface of the reflective element 143 (the surface of the reflective element 143 facing away from the inner wall of the light-transmitting hole 142a) is also inclined relative to the Z-axis direction.

[0049] In this embodiment, the angle between the reflective element 143 and the Z-axis direction can be from 45 degrees to 60 degrees, for example, 45 degrees, 48 ​​degrees, 50 degrees, 53 degrees, 55 degrees, 57 degrees, 60 degrees, or other values. This application does not impose specific limitations on this. The Z-axis direction is parallel to the forward viewing direction of the display panel 10, that is, the angle between the reflective element 143 and the forward viewing direction of the display panel 10 can also be from 45 degrees to 60 degrees. The material of the reflective element 143 may include at least one metal with good reflective properties, such as aluminum, silver, palladium, nickel, platinum, etc.

[0050] In this embodiment, the position of one of the reflective elements 143 corresponds to the periphery of one of the first color resists 123a, that is, the orthographic projection of one of the reflective elements 143 in the Z-axis direction coincides with the orthographic projection of the periphery of one of the first color resists 123a in the Z-axis direction. Similarly, the position of one of the reflective elements 143 corresponds to the periphery of one of the second color resists 123b, that is, the orthographic projection of one of the reflective elements 143 in the Z-axis direction coincides with the orthographic projection of the periphery of one of the second color resists 123b in the Z-axis direction. Finally, the position of one of the reflective elements 143 corresponds to the periphery of one of the third color resists 123c, that is, the orthographic projection of one of the reflective elements 143 in the Z-axis direction coincides with the orthographic projection of the periphery of one of the third color resists 123c in the Z-axis direction.

[0051] Understandably, by aligning the position of the reflective element 143 with the periphery of the first color resist 123a, the reflective element 143 can receive and reflect more of the first color light without making the size of the first color resist 123a too large. Similarly, by aligning the position of the reflective element 143 with the periphery of the second color resist 123b, the reflective element 143 can receive and reflect more of the second color light without making the size of the second color resist 123b too large. Likewise, by aligning the position of the reflective element 143 with the periphery of the third color resist 123c, the reflective element 143 can receive and reflect more of the third color light without making the size of the third color resist 123c too large. It is understood that excessively large sizes of the first color resist 123a, the second color resist 123b, and the third color resist 123c are detrimental to forming a high-resolution display panel 10.

[0052] In this embodiment, both the common electrode 144 and the pixel electrode 125 are made of indium tin oxide (ITO).

[0053] In summary, the display panel 10 provided in this application embodiment includes a first substrate assembly 12 and a second substrate assembly 14 arranged opposite to and spaced apart. The first substrate assembly 12 includes a plurality of first color resists 123a, a plurality of second color resists 123b, and a plurality of third color resists 123c, which are arranged sequentially at intervals. The second substrate assembly 14 includes a light-shielding layer 142 and a plurality of reflective elements 143. The light-shielding layer 142 has a plurality of light-transmitting holes 142a, the position of one light-transmitting hole 142a corresponding to the position of one color resist, and one reflective element 143 disposed on the inner wall of one light-transmitting hole 142a. The first color resist 123a converts backlight into a first color light, the second color resist 123b converts backlight into a second color light, and the third color resist 123c converts backlight into a third color light. The reflective element 143 reflects the first color light, the second color light and the third color light to the oblique viewing angle of the display panel 10, thereby preventing color shift of the light emitted from the oblique viewing angle of the display panel 10.

[0054] The third embodiment of this application provides a method for manufacturing a display panel, which is used to manufacture the aforementioned display panel. For descriptions of the structural similarities between the manufacturing method and the display panel, please refer to the relevant descriptions of the display panel; they will not be repeated here.

A portion of the solution of the light-shielding layer 142 is illuminated through a photomask, and the illuminated portion of the solution of the light-shielding layer 142 solidifies to form the light-shielding layer 142. The solution of the light-shielding layer 142 is then removed using a first specific solvent. The light-shielding layer 142 surrounds the periphery of each first sub-common electrode 144a, and is spaced apart from each first sub-common electrode 144a.

[0059] S30. A reflective structure 143a is formed on the side of the light-shielding layer 142 opposite to the second substrate 141 and on the periphery of the light-shielding layer 142.

A solution of the reflective structure 143a is coated onto the light-shielding layer 142. The solution of the reflective structure 143a includes a photosensitive material. A portion of the solution of the reflective structure 143a is illuminated through a photomask, and the illuminated portion of the solution solidifies to form the reflective structure 143a. The solution of the reflective structure 143a is then removed using a second specific solvent.

[0061] S40. Remove the reflective structure 143a on the side of the light-shielding layer 142 facing away from the second substrate 141 to form a reflective element 143.

[0062] Specifically, please refer to Figure 7 , Figure 7 for Figure 3 The diagram shows the structure formed in step S40 of the display panel manufacturing method. A third specific solvent is applied to the side of the light-shielding layer 142 facing away from the second substrate 141, removing the reflective structure 143a on that side and retaining the reflective structure 143a on the periphery of the light-shielding layer 142 to form the reflective element 143. The third specific solvent can also remove the light-shielding layer 142, allowing the solvent to control the thickness of both the light-shielding layer 142 and the reflective element 143.

[0063] In this embodiment of the application, the thickness of the light-shielding layer 142 is the same as the thickness of the reflective element 143.

[0064] S50. A plurality of second sub-common electrodes 144b are formed on the side of the light-shielding layer 142 opposite to the second substrate 141. The second sub-common electrodes 144b cover the reflective element 143. The first sub-common electrode 144a and the second sub-common electrodes 144b constitute a common electrode 144. The second substrate 141, the light-shielding layer 142, the reflective element 143 and the common electrode 144 constitute the second substrate assembly 14.

[0065] Specifically, please refer to Figure 8 , Figure 8 for Figure 3 The diagram shows the structure formed in step S50 of the display panel manufacturing method. Multiple second sub-common electrodes 144b are formed by physical vapor deposition on the side of the light-shielding layer 142 facing away from the second substrate 141, the side of the reflective element 143 facing away from the second substrate 141, and the side of the reflective element 143 facing away from the light-shielding layer 142. The second sub-common electrodes 144b cover the reflective element 143, and are connected to the first sub-common electrode 144a, together forming a common electrode 144. The second substrate 141, the light-shielding layer 142, the reflective element 143, and the common electrode 144 constitute the second substrate assembly 14.

[0066] S60. A first substrate assembly 12 is provided, and the first substrate assembly 12 and the second substrate assembly 14 are assembled to form a display panel.

[0067] Specifically, after aligning the first substrate assembly 12 and the second substrate assembly 14, liquid crystal is filled between the first substrate assembly 12 and the second substrate assembly 14, and then the first substrate assembly 12 and the second substrate assembly 14 are bonded together using a sealing adhesive. The "alignment" refers to the process of aligning the first substrate 121 of the first substrate assembly 12 with the second substrate 141 of the second substrate assembly 14, and then bonding the first substrate assembly 12 and the second substrate assembly 14 together using a sealing adhesive.

[0068] Understandably, the display panel manufacturing method provided in this application embodiment uses the same mask in step S20 and step S30, that is, the formation of the light-shielding layer 142 and the formation of the reflective structure 143a share the same mask. Then, in step S40, the excess part of the reflective structure 143a is removed together to form the reflective element 143 and the excess part of the light-shielding layer 142 is removed, which simplifies the manufacturing process of the display panel and reduces the cost.
