Since a manufacturer of a television or a display panel usually needs to set its Logo when assembling the television, an extra position of a border is required to be set for placing the Logo, which makes it impossible to realize a borderless product. In the scheme, the identification pattern 132 is, for example, HKC, the identification pattern 132 is directly arranged in the non-display area of the display panel, the first light shielding layer and the second light shielding layer of the first substrate and the second substrate are both provided with the first opening and the second opening which are light-permeable, namely, the preset identification pattern 132 which is light-permeable is formed by the corresponding arrangement of the first opening and the second opening, the purpose of arranging the identification pattern in the non-display area is realized, so that no additional frame is needed to be arranged, the frameless design of the television or the display panel is realized, when the television or the display panel does not work, only one piece of glass can be arranged on the front side, like an artwork, the appearance and the taste of the television/the display panel are improved, and the additional value of the television/the display panel is improved.
Specifically, the first opening and the second opening may be arranged in a hollow area, wherein the hollow area is completely transparent, or the first opening and the second opening are not completely hollow, but a plurality of through holes are arranged to allow the light source to penetrate through, and the plurality of through holes are partially transparent, or other suitable arrangements are possible. As long as the shape and size of the overlapping area of the first opening and the second opening correspond to the preset identification pattern, that is, the opening mode is not limited to these two modes, and other modes capable of allowing the light source to pass through are all possible.
The first substrate 113 is an array substrate, and the second substrate 115 is a color film substrate. The first substrate 113 includes a first polarizer 128, a first light shielding layer 117, a glass substrate 131 and a first film layer 130, the first light shielding layer 117 is located between the first polarizer 128 and the glass substrate 131, the first film layer 130 is close to the liquid crystal layer 114, and the first film layer 130 may be provided with one or more of a metal layer, an insulating layer, a passivation layer and other film layers as required. The second substrate 115 includes a second light-shielding layer 118, a glass substrate 131, and a second polarizer 129, and the second light-shielding layer 118 is disposed on the glass substrate 131 of the second substrate 115 and close to the liquid crystal layer 114.
The non-display area 112 includes a long side 124 and a short side 125, the length of the long side 124 is greater than the length of the short side 125, the long side 124 includes a first long side 126 and a second long side 127, and the width of the first long side 126 is greater than or equal to the width of the second long side 127. The preset identification pattern may be disposed on any one side of the non-display area, for example, may be disposed on the first long side 126, and optionally, may be disposed in a middle area of the first long side 126; of course, the first long side 126 may be wider than the other sides, if necessary, to better set Logo. Of course, the Logo pattern may not be disposed in the middle area of the first long side 126, or may be disposed in the short side, and even the Logo includes a plurality of Logo patterns (e.g., letters or chinese characters), but may be disposed on at least two sides of the non-display area to form a complete Logo, which is beneficial to realizing a borderless design.
As shown in fig. 7, W is a width direction of the cross-sectional view, in an embodiment, the opening widths of the first opening 119 and the second opening 120 are equivalent, and the opening edges of the first opening and the second opening are aligned. Where the width of the openings is comparable means that the shapes are the same and the edges of the openings are aligned, the sides being aligned in the vertical direction. Since the light of the backlight passes through the first opening 119 and the second opening 120, so that the predetermined identification pattern is displayed, when the widths of the openings through which the light sources pass are equal, the integrity of the predetermined identification pattern can be displayed more uniformly, and the visual experience of the user is better.
Of course, it is also possible that the opening widths of the first opening 119 and the second opening 120 are not equal.
Specifically, as shown in fig. 8, the opening width of the first opening 119 is smaller than the opening width of the second opening 120. When the opening width of the first opening 119 is smaller than the opening width of the second opening 120, the corresponding positions of the first light shielding layer 117 and the second opening 120 are overlapped, so that the identification pattern corresponding to the overlapped area is darker, and the identification pattern corresponding to the position through which light passes is brighter, so that the display brightness of the identification pattern gradually changes from bright to dark, and a layering effect is presented to improve the visual experience of a user.
In an embodiment, in the first light-shielding layer 117, a region where the second opening 120 and the first light-shielding layer 117 are correspondingly overlapped is a first semi-transparent region 121, and a thickness of the first semi-transparent region 121 is smaller than a thickness of other regions in the first light-shielding layer 117. Because the opening width of the first opening 119 is smaller than that of the second opening 120, when light is emitted from the second opening 120 to the first opening 119, the transmittance of the light source is reduced at the overlapping position of the second opening 120 and the first light shielding layer 117, and the thickness of the first semi-transparent region 121 provided with the first light shielding layer 117 is smaller than that of other regions in the first light shielding layer 117, so that part of the light can penetrate through the first semi-transparent region 121, and the display brightness of the preset identification pattern gradually changes from bright to dim to full dim, thereby presenting a hierarchical sense and improving the visual experience of a user.
In the first light shielding layer 117, an area where the second opening 120 and the first light shielding layer 117 are correspondingly overlapped is a first semi-transparent area 121, and the first semi-transparent area 121 is provided with a plurality of through holes to transmit light, so that although part of light transmitted by the second opening 120 is blocked by the first semi-transparent area 121, the first semi-transparent area 121 is perforated, and a light source passes through the perforated area, so that the last preset identification pattern shows a star point effect to improve a visual effect.
In one embodiment, as shown in fig. 9, the opening width of the first opening 119 is greater than the opening width of the second opening 120. When the opening width of the first opening 119 is greater than the opening width of the second opening 120, the corresponding positions of the second light shielding layer 118 and the first opening 119 are overlapped, so that the corresponding preset identification pattern of the overlapped area is dark, and the corresponding position of the light passing through is bright, so that the display brightness of the preset identification pattern is gradually changed from bright to dark, a layering effect is presented, and the visual experience of a user is improved.
In an embodiment, in the second light shielding layer 118, a region where the first opening 119 and the second light shielding layer 118 are correspondingly overlapped is a second semi-transparent region 122, and a thickness of the second semi-transparent region 122 is smaller than that of other regions in the second light shielding layer 118. Because the opening width of the first opening 119 is greater than the opening width of the second opening 120, when the light source is emitted from the second opening 120 to the first opening 119, the overlapping position of the first opening 119 and the second light shielding layer 118 reduces the transmittance of the light source, and the thickness of the second semi-transparent region 122 provided with the second light shielding layer 118 is less than the thickness of other regions in the second light shielding layer 118, so that part of light can penetrate through the second semi-transparent region 122, and the display brightness of the preset identification pattern gradually changes from bright to dim to full dim, thereby presenting a hierarchical sense and improving the visual experience of the user.
In the second light-shielding layer 118, an area where the first opening 119 and the second light-shielding layer 118 are correspondingly overlapped is a second semi-transparent area 122, and the second semi-transparent area 122 is provided with a plurality of through holes, so that although light is blocked by the second semi-transparent area 122, the light passes through the area where the through holes are formed by arranging the second semi-transparent area 122 with the plurality of through holes, so that the effect of a star point is shown by the last preset identification pattern, and the visual effect is improved.
In one embodiment, the opening width of the first opening 119 ranges from 100 micrometers to 2 centimeters, and the opening width of the second opening 120 ranges from 100 micrometers to 2 centimeters. When the opening range of the first opening 119 and the second opening 120 falls between 100 μm and 2 cm, this dimension is just visible to the human eye in the peripheral area, and thus the dimension is neither too large nor too small. If the size of the opening is too large, too much space is occupied, and space is wasted; if the size of the opening is set too small, the opening is not easy for human eyes to recognize.
In an embodiment, as shown in fig. 10, where x is a direction of a first polarization transmission axis and y is a direction of a second polarization transmission axis, the first polarization transmission axis of the first polarizer and the second polarization transmission axis of the second polarizer are orthogonally arranged, and the display panel employs a twisted nematic driving technique. First polarisation is passed through the axle with the second polarisation is passed through the axle quadrature, and liquid crystal layer 114 rotates the light polarization state 90 degrees, and when having backlight like this, the light that the backlight sent is rotated 90 degrees back for first polarisation is passed through the axle and is passed through the axle unanimous with the second polarisation, and light just can be passed through like this to can show predetermined identification pattern (Logo).
As shown in fig. 11, x is the direction of the first polarized light transmission axis, and y is the direction of the second polarized light transmission axis. When the first polarized light transmission axis of the first polarized light sheet is parallel to the second polarized light transmission axis of the second polarized light sheet, the display panel adopts a vertical alignment driving technology or a fringe field switching technology. When the first polarized light transmission axis and the second polarized light transmission axis are parallel, the liquid crystal which is not polarized light is arranged in a balanced state, so that the polarized state of light is not changed, and when backlight passes through, the light source can transmit output, thereby displaying Logo.
Certainly can be provided with the opening with the corresponding first opening of polaroid or the position correspondence of second opening as required, so make the light's that is shaded and see through the rate higher to make predetermined identification pattern luminance brighter, promote user's visual experience.

The non-display area of first base plate includes first polaroid, first light shield layer, glass substrate and first rete, first light shield layer is located first polaroid with between the glass substrate, first rete is close to the liquid crystal layer, first light shield layer with the corresponding position of predetermineeing the identification pattern is provided with first opening, the second base plate includes second light shield layer, glass substrate and second polaroid, the second light shield layer is close to the liquid crystal layer sets up on the glass substrate of second base plate, the non-display area of second base plate includes the second light shield layer, the second light shield layer with the corresponding position of predetermineeing the identification pattern is equipped with the second opening, first opening with the second opening is all light-permeable, first opening with second open-ended opening width equals.
In this scheme, the direct setting of identification pattern is in display panel's non-display area, and first light shield layer and the second light shield layer on first base plate and second base plate all are provided with light-permeable first opening and second opening, set up the predetermined identification pattern that forms light-permeable through first opening and second open-ended correspondence promptly, realize setting up the purpose of identification pattern in non-display area, so just need not additionally set up the frame again, realized TV set or display panel's frameless design.
