[0043] The present invention provides a display device, which comprises the display panel of the present invention.
[0044] Example 1
[0045] like Figure 1 As shown, the display panel includes: a scan line 110 , a data line 120 , a sub-pixel 130 , a first light shielding unit 140 , and a second light shielding unit 150 .
[0046] The plurality of scan lines 110 extend along the first direction M and are spaced apart from each other.
[0047] The plurality of data lines 120 extend along a second direction N and are spaced apart from each other. The second direction N intersects the first direction M. In this embodiment, the second direction N is perpendicular to the first direction M.
[0048] A plurality of sub-pixels 130 are defined by the intersection of the scan line 110 and the data line 120. The sub-pixels 130 include a first sub-pixel 131, a second sub-pixel 132, and a third sub-pixel 133 of different colors. In this embodiment, the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 are red sub-pixels, green sub-pixels, and blue sub-pixels, respectively.
[0049] like Figure 3 As shown, each of the sub-pixels 130 includes a stacked substrate 1, a light shielding layer 2, a first insulating layer 3, an active layer 4, a second insulating layer 5, a gate 6, a first interlayer insulating layer 7, a source and drain layer 8, a second interlayer insulating layer 9, a conductive layer 10, a first planarizing layer 11, a pixel electrode 12, a passivation layer 13, a common electrode 14 and a second planarizing layer 15.
[0050] The pixel electrode 12 is loaded with a first voltage, and an electric field is formed between the pixel electrode 12 and the common electrode 14 to drive the liquid crystal to display.
[0051] like Figure 1 and Figure 2 As shown, a plurality of first shading units 140 extend along the first direction M. On a plane formed by the first direction M and the second direction N, the orthographic projection of the first shading unit 140 at least partially overlaps with the orthographic projection of the scanning line 110. Figure 1 and Figure 2As shown, a plurality of second shading units 150 extend along the second direction N. On the plane formed by the first direction M and the second direction N, the orthographic projection of the second shading unit 150 at least partially overlaps with the orthographic projection of the data line 120. Among them, at least one of the first shading unit 140 and the second shading unit 150 is loaded with a second voltage, and the polarity of the second voltage is the same as the polarity of the first voltage. At least one of the first shading unit 140 and the second shading unit 150 forms an additional electric field with the common electrode 14, and this additional electric field can strengthen the electric field originally formed between the pixel electrode 12 and the common electrode 14, thereby improving the transmittance of the display panel without color mixing. The polarity of the second voltage is the same as the polarity of the first voltage, so that at least one of the first shading unit 140 and the second shading unit 150 has the same polarity as the pixel electrode 12, thereby avoiding the additional electric field formed by at least one of the first shading unit 140 and the second shading unit 150 and the common electrode 14 and the electric field between the pixel electrode 12 and the common electrode 14 being opposite to deteriorate the liquid crystal efficiency.
[0052] In this embodiment, the first light shielding unit 140 and the second light shielding unit 150 are both loaded with a second voltage, and the polarity of the second voltage is the same as the polarity of the first voltage. Specifically, in this embodiment, at least one of the first light shielding unit 140 and the second light shielding unit 150 is made of a light shielding conductive material, such as a metal that can both shield light and conduct electricity. Thus, the second voltage can be directly applied to the first light shielding unit 140 and the second light shielding unit 150.
[0053] like Figure 3 and Figure 4 As shown, the display panel includes: an array substrate 100 and a color filter substrate 200 arranged opposite to each other. In this embodiment, the first light shielding unit 140 and the second light shielding unit 150 are both arranged in the color filter substrate 200. In other embodiments, the first light shielding unit 140 and the second light shielding unit 150 can be both arranged in the array substrate 100; or, the first light shielding unit 140 and the second light shielding unit 150 are respectively arranged in one of the array substrate 100 and the color filter substrate 200.
[0054] like Figure 4 As shown, in this embodiment, a photoresist layer 300 is disposed inside the color filter substrate 200. In other embodiments, the photoresist layer 300 may also be disposed inside the array substrate 100, that is, a COA (Color Filter on Array) structure.
[0055] like Figure 4As shown, the photoresist layer 300 includes a first photoresist layer 301, a second photoresist layer 302 and a third photoresist layer 303 respectively arranged corresponding to the first sub-pixel 131, the second sub-pixel 132 and the third sub-pixel 133. Specifically, the first photoresist layer 301, the second photoresist layer 302 and the third photoresist layer 303 are a red photoresist layer, a green photoresist layer and a blue photoresist layer respectively.
[0056] like Figure 5 As shown, when the first shading unit and the second shading unit in the prior art are not loaded with the second voltage, dark lines exist locally in the display image.
[0057] like Figure 6 As shown, after the first shading unit and the second shading unit of this embodiment are loaded with the second voltage, the display image is compared with Figure 5 In terms of brightness, the uniformity has been improved, and the Figure 5 The local dark pattern problem in .
[0058] like Figure 7 and Figure 8 As shown, the present embodiment is simulated by simulation software and it is found that R, G, B, and W in the figure represent the transmittance curves of red sub-pixels, green sub-pixels, blue sub-pixels, and white light when no photoresist layer is provided. After the display panel of the present embodiment applies the second voltage to the first shading unit 140 and the second shading unit 150 at the same time, the light transmittance of the display panel of the present embodiment is improved by 12% compared with the display panel in the prior art to which the second voltage is not applied.
[0059] Example 2
[0060] like Fig. 9 and Fig.10 As shown, this embodiment includes most of the technical features of embodiment 1, and the difference between this embodiment and embodiment 1 is that, in this embodiment, the first shading units 140 on both sides of at least one second shading unit 150 are arranged at intervals. When one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first shading unit 140 corresponding to the sub-pixel 130 is 0V, thereby avoiding affecting the dark state of the sub-pixel 130 and improving the contrast of the display panel.
[0061] In other embodiments, the second light shielding units 150 on both sides of at least one of the first light shielding units 140 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the second light shielding unit 150 corresponding to the sub-pixel 130 is 0V; the first light shielding units 140 on both sides of at least one of the second light shielding units 150 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first light shielding unit 140 corresponding to the sub-pixel 130 is 0V, and at the same time, the second light shielding units 150 on both sides of at least one of the first light shielding units 140 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the second light shielding unit 150 corresponding to the sub-pixel 130 is 0V. In this way, the dark state of the sub-pixel 130 can be avoided from being affected, and the contrast of the display panel can be improved.
[0062] Example 3
[0063] like Fig.11 and Fig.12 As shown, this embodiment includes most of the technical features of the embodiment 1. The difference between this embodiment and the embodiment 1 is that, in this embodiment, at least one of the first light shielding unit 140 and the second light shielding unit 150 includes: a first electrode 400 and a light shielding body 500. The first electrode 400 of the first light shielding unit 140 is arranged between the light shielding body 500 and the scanning line 110, and the first electrode 400 of the second light shielding unit 150 is arranged between the light shielding body 500 and the data line 120. On the plane formed by the first direction M and the second direction N, the orthographic projection of the light shielding body 500 at least partially overlaps with the orthographic projection of the first electrode 400.
[0064] The light shielding body 500 is made of insulating material, such as black resin.
[0065] The material of the first electrode 400 is a conductive material. In this embodiment, the material of the first electrode 400 is ITO. In other embodiments, the material of the first electrode 400 may also be a conductive metal.
[0066] In this embodiment, the first electrode 400 is loaded with the second voltage, and the polarity of the second voltage is the same as the polarity of the first voltage. At least one of the first light shielding unit 140 and the second light shielding unit 150 forms an additional electric field with the common electrode 14, and this additional electric field can strengthen the electric field formed between the pixel electrode 12 and the common electrode 14, thereby improving the transmittance of the display panel without color mixing. Among them, the polarity of the second voltage is the same as the polarity of the first voltage, that is, the polarity of the second voltage loaded by at least one of the first light shielding unit 140 and the second light shielding unit 150 is the same as the polarity of the pixel electrode 12, avoiding the additional electric field formed by at least one of the first light shielding unit 140 and the second light shielding unit 150 and the common electrode 14 and the electric field between the pixel electrode 12 and the common electrode 14, which is opposite to the deterioration of the liquid crystal efficiency.
[0067] Example 4
[0068] like Fig.13 and Fig.14 As shown, this embodiment includes most of the technical features of Embodiment 3, and the difference between this embodiment and Embodiment 3 is that, in this embodiment, the first electrodes 400 on both sides of at least one of the second light shielding units 150 are arranged at intervals. When one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first electrode 400 of the first light shielding unit 140 corresponding to the sub-pixel 130 is 0V, thereby avoiding affecting the dark state of the sub-pixel 130 and improving the contrast of the display panel.
[0069] In other embodiments, the second light shielding units 150 on both sides of at least one of the first light shielding units 140 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first electrode 400 of the second light shielding unit 150 corresponding to the sub-pixel 130 is 0V; or the first light shielding units 140 on both sides of at least one of the second light shielding units 150 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first electrode 400 of the first light shielding unit 140 corresponding to the sub-pixel 130 is 0V, and at the same time, the second light shielding units 150 on both sides of at least one of the first light shielding units 140 may be arranged at intervals, and when one of the sub-pixels 130 is in a dark state, the second voltage loaded on the first electrode 400 of the second light shielding unit 150 corresponding to the sub-pixel 130 is 0V. In this way, the dark state of the sub-pixel 130 can be avoided from being affected, and the contrast of the display panel can be improved.
[0070] Example 5
[0071] like Fig.15As shown, this embodiment includes most of the technical features of the embodiment 1. The difference between this embodiment and the embodiment 1 is that in this embodiment, the first light shielding unit 140 is arranged in the array substrate 100, and the second light shielding unit 150 is arranged in the color filter substrate 200. The photoresist layer 300 is arranged in the array substrate 100, that is, the COA (Color Filter on Array) structure.
[0072] When the first light shielding unit 140 and the second light shielding unit 150 are respectively disposed in one of the array substrate 100 and the color filter substrate 200, the second voltage is loaded on one of the first light shielding unit 140 and the second light shielding unit 150. This prevents the first light shielding unit 140 and the second light shielding unit 150 from being loaded with the second voltage at the same time, so as to prevent interference between the additional electric field formed by the first light shielding unit 140 and the common electrode 14 and the additional electric field formed by the second light shielding unit 150 and the common electrode 14.
[0073] like Fig.16 As shown, when the first shading unit and the second shading unit in the prior art are not loaded with the second voltage, dark lines exist locally in the display image.
[0074] like Fig.17 As shown, after the first shading unit of this embodiment is loaded with the second voltage, the display image is compared with Fig.16 In terms of brightness, uniformity has been improved, and the Fig.17 The local dark pattern problem in .
[0075] like Fig.18 and Fig.19 As shown, in this embodiment, a second voltage is applied to the first shading unit 140 in the array substrate 100. After simulation with simulation software, it is found that after the display panel of this embodiment applies the second voltage to the first shading unit 140, the light transmittance of the display panel of this embodiment is improved by 4% compared with the display panel in the prior art to which the second voltage is not applied.
[0076] It is worth noting that, in the present embodiment, the first light shading unit 140 and the common electrode 14 are both located in the array substrate 100, on the same side of the liquid crystal layer. The electric field generated by the first light shading unit 140 and the common electrode 14 will not affect the liquid crystal molecules of the liquid crystal layer. Therefore, in the present embodiment, the first light shading unit 140 does not need to be designed in blocks, that is, there is no need to set the first light shading units 140 on both sides of the second light shading unit 150 at intervals.
[0077] The above is a detailed introduction to a display panel and a display device provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
