Fig. 1 is a schematic diagram of a top view structure of a display panel, and fig. 2 is a schematic diagram of a cross-sectional view of the display panel. As shown in fig. 1 and 2, the display panel includes a substrate and a Printed Circuit Board (PCBA), the Printed Circuit Board 123 is made of COF (Chip On Film) material as a base, the substrate includes a first substrate 113 and a second substrate 115, a liquid crystal layer 114 is disposed between the first substrate 113 and the second substrate 115, a backlight module 116 is disposed On a side close to the second substrate 115, and the display panel includes a display region 111. The PCBA is connected with the substrate, bent downwards and attached to the lower surface of the substrate, and the PCBA can be hidden between the back plate and the display panel, so that the display panel and the back plate are attached through the adhesive, when a user watches a television from the upper surface of the substrate, the PCBA cannot be seen, the user only sees the front glass substrate, and therefore the extremely narrow-frame or frameless television is achieved.
Fig. 3 is a schematic diagram of a display panel coated with a black material on a surface layer, as shown in fig. 3, the display panel includes a display region 111 and a non-display region 112, and since the substrate faces a viewer, when the viewer views the display panel, the metal layer of the substrate is seen to reflect light, which affects the viewing effect. Therefore, the surface of the substrate is coated with a Black light-shielding material, such as a Black resin material like BM (Black Matrix) or other Black materials, to prevent the viewer from seeing the metal reflection. When we assemble a television or a display, a television or display manufacturer usually needs to set a Logo (Logo is an identification pattern or a brand), so a border exists at the Logo setting side, which is not favorable for realizing a borderless design.
The present application is described in detail below with reference to the figures and alternative embodiments.
As shown in fig. 4, 5, 6 and 7, fig. 4 is a schematic structural block diagram of a display device, fig. 5 is a schematic top view of a display panel, fig. 6 is a schematic cross-sectional view of the display panel, and fig. 7 is a schematic cross-sectional view of a non-display area of the display panel. In one embodiment, a display device 100 includes a display panel 110, the display panel 110 is divided into a display area 111 and a non-display area 112, the non-display area 112 is located at the periphery of the display area 111, and the non-display area 112 is provided with an identification pattern 134. The display panel 110 includes a first substrate 113, a second substrate 115, and a backlight module 116, wherein the backlight module 116 is disposed on a side of the second substrate 115 away from the first substrate 113. The first substrate 113 is provided with a first light shielding layer 117 and a first polarizer 128 corresponding to the non-display region, and the first light shielding layer 117 is provided with a first opening 119; a second light shielding layer 118 and a second polarizer 129 are disposed on the second substrate 115 corresponding to the non-display region, and the second light shielding layer 118 is provided with a second opening 120; the first opening 119 and the second opening 120 are correspondingly disposed, and at least one of the first polarizer 128 and the second polarizer 129 is opened at a position corresponding to the first opening 119 and the second opening 120 to form a logo 134.
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 bezel is required to be set for placing the Logo, which is not favorable for realizing a frameless design. In this scheme, the logo pattern 134, such as HKC, is directly disposed in the non-display region of the display panel, and the first light-shielding layer of the first substrate and the second light-shielding layer of the second substrate are both provided with a first opening and a second opening that are light-permeable, and a position of the first polarizer corresponding to the first opening is also opened, or a position of the second polarizer corresponding to the second opening is also opened. The backlight module is provided with a light source, and light rays emitted by the light source penetrate through the first opening, the second opening and the opening of the first polaroid or the opening of the second polaroid. Because the polaroid is generally between 30 ~ 60% to the transmissivity of light, set up the opening at the polaroid, make the transmissivity increase of the light that the light source sent, under the same backlight unit prerequisite, make the identification pattern brighter, just so can realize showing brighter identification pattern in non-display area, just need not additionally set up the frame again, the no frame design of TV set or display panel has been realized, in TV set or display panel work, realize the Logo and show, when TV set or display panel are out of work, the front can only be a piece of glass, if like the work of art, the outward appearance taste of TV set/display panel has been promoted, its added value has been promoted.
The liquid crystal layer is not needed to be arranged in the area corresponding to the non-display area, so that the using amount of liquid crystal can be reduced, and the cost is further saved.
Specifically, the first opening 119 and the second opening 120 may be hollow areas, where the hollow areas are completely transparent areas, or the first opening 119 and the second opening 120 are not completely hollow areas and are partially transparent areas, but a plurality of through holes are provided to allow the light source to penetrate through, or other suitable arrangements are possible. As long as the shape of the overlapping area of the first opening and the second opening corresponds 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. Similarly, the first polarizer may be arranged in a manner of a hollow area or a plurality of through holes corresponding to the position opening of the first opening, or the second polarizer may be arranged in a manner of a position opening corresponding to the second opening.
The shape of the first opening and the second opening is not limited, but the shape of the overlapping area of the first opening and the second opening needs to correspond to a preset identification pattern.
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 formed preset identification pattern 134 may be disposed on any one side of the non-display area 112, for example, may be disposed on the first long side 126, and optionally, may be disposed in the 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 134 may not be disposed in the middle area of the first long side 126, or may be disposed in the short side 125, 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.
The first polarizer 128 is provided with a third opening 132 corresponding to the second opening 120, and the second polarizer 129 is not provided with an opening corresponding to the second opening 120. The transmittance of one polarizer to light is generally 30-60%, so that the light transmitted out from the backlight is not too bright or too dark, and an opening is formed in the position of one polarizer corresponding to the light shielding layer, so that the transmitted brightness of the light source is increased, and the display brightness of the preset identification device is brighter.
As shown in fig. 7, W is a width direction of the cross-sectional view, and specifically, an opening width of the third opening 132 is equal to an opening width of the first opening 119. When the width of the opening is equal, the shape and the size are the same, the edges of the opening are aligned, and all the edges are aligned in the vertical direction. When the opening width of the third opening 132 is equal to the opening width of the second opening 120, the light passing through the second opening 120 can completely pass through the third opening 132, and the light is uniformly passed through, so that the overall display brightness of the logo pattern is relatively uniform. Of course, it is also possible that the opening width of the third opening 132 is not equal to the opening width of the second opening 120. The opening width of the third opening 132 is smaller than the opening width of the second opening 120, when the opening width of the third opening 132 is smaller than the opening width of the second opening 120, the brightness of the logo pattern corresponding to the third opening 132 is brighter than the brightness of other parts, the brightness of the logo pattern corresponding to the overlapping part of the second opening 120 and the first polarizer 128 is darker, and the process of gradually changing the brightness of the logo pattern presents a hierarchical feeling to improve the visual experience of a user.
Optionally, as shown in fig. 8, a fourth opening 133 is disposed at a position of the second polarizer 129 corresponding to the second opening 120, and no opening is disposed at a position of the first polarizer 128 corresponding to the first opening 119. The transmittance of the polarizer to light is generally between 30% and 60%, and an opening is formed in a position of one polarizer corresponding to the light shielding layer, so that the transmitted brightness of the light source is increased, and the display brightness of the preset identification device is brighter.
The opening width of the fourth opening 133 is equal to the opening width of the second opening 120. When the opening width of the fourth opening 133 is equal to the opening width of the second opening 120, the light passing through the second opening 120 can substantially pass through the fourth opening 133, and the light is uniformly passed through, so that the overall display brightness of the logo pattern is relatively uniform. Of course, it is also possible that the opening width of the fourth opening 133 is not equal to the opening width of the second opening 120. The opening width of the fourth opening 133 is smaller than the opening width of the third opening 132, when the opening width of the fourth opening 133 is smaller than the opening width of the second opening 120, the brightness of the logo pattern corresponding to the fourth opening 133 is brighter than the brightness of other parts, the brightness of the logo pattern corresponding to the overlapping part of the second opening 120 and the second polarizer 129 is darker, and the logo pattern has a process of gradually changing brightness, so that a layered feeling is presented to improve the visual experience of a user.
In one embodiment, as shown in fig. 9, the first polarizer 128 is a third opening 132 corresponding to the first opening 119, and the second polarizer 129 is a fourth opening 133 corresponding to the second opening 120. The third opening 132 and the fourth opening 133 are both opened, and because both the two polarizers are provided with openings, compared with a scheme that only one opening is arranged or no opening is arranged, the transmittance of light is greatly improved, so that the whole identification pattern is more striking and bright.
The third opening 132 and the fourth opening 133 have the same size, the opening widths of the third opening 132 and the fourth opening 133 are the same, and the edges of the first opening 119, the second opening 120, the third opening 132 and the fourth opening 133 are aligned, so that the method is easy to realize in process and simple to operate. Specifically, the opening widths of the first opening 119, the second opening 120, the third opening 132 and the fourth opening 133 are equal, and when the opening widths of the light shielding layer and the polarizer are set to be the same, on one hand, light emitted from the backlight module is less lost in the process of passing through the light shielding layer and the polarizer, so that the brightness of the logo pattern is more striking and brighter; on the other hand, the four openings are equal in width, and the process is simple to realize.
Of course, the opening width of the polarizer and the opening width of the light-shielding layer are not equal. The opening width of the first opening 119 is greater than the opening width of the third opening 132, the opening width of the second opening 120 is greater than the opening width of the fourth opening 133, and the opening width of the first opening 119 is equal to the opening width of the second opening 120. When the opening width of the polarizer is smaller than that of the shading layer, the transmittance of light is influenced to a certain degree by the polarizer, and when the opening of the polarizer is small, the brightness of the identification pattern can be controlled to be not so bright, so that better visual experience is provided for a user.
The first opening 119 and the second opening 120 have the same opening width, and the third opening 132 and the fourth opening 133 have different opening widths, wherein the opening width of the third opening 132 is greater than the opening width of the fourth opening 133, and the opening width of the third opening 132 is smaller than or equal to the opening width of the first opening 119. Of course, the opening width of the fourth opening 133 is larger than the opening width of the third opening 132, and the opening width of the fourth opening 133 is smaller than or equal to the opening widths of the first opening 119 and the second opening 120. When the opening width of the polarizer with the larger opening is smaller than that of the shading layer, the opening width of the polarizer limits the light transmittance, so that the size of the polarizer can be controlled, the brightness of the identification pattern is limited, and better visual experience is provided for a user.
The opening widths of the first opening 119 and the second opening 120 are different, the opening width of the first opening 119 is smaller than the opening width of the second opening 120, the opening widths of the third opening 132 and the fourth opening 133 are equal, and the opening width of the third opening 132 is smaller than or equal to the opening width of the first opening 119. The opening width of polaroid equals, and is less than the opening width of the less light shield layer of opening, and what the polaroid was provided with the open-ended like this, luminance is brightest, and other first opening 119 or second opening 120 do not correspond to the polaroid to have the open-ended luminance darker to make the display luminance of identification pattern by bright towards dark gradual change, demonstrate a stereovision, in order to promote user visual experience.
Specifically, as shown in fig. 10, when the third opening 132 and the fourth opening 133 are equal, a portion of the first light-shielding layer where the second opening 120 and the first light-shielding layer 117 overlap each other is a first semi-transparent region 121, and the thickness of the first semi-transparent region 121 is smaller than the thickness of the other portion of the first light-shielding layer. Because the opening width of the first opening 119 is smaller 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 transmittance of the light source is reduced at the position where the second opening 120 and the first light shielding layer are overlapped, and the thickness of the first semi-transparent region 121 provided with the first light shielding layer is smaller than the thickness of other parts in the first light shielding layer, so that part of the light source can penetrate through the first semi-transparent region 121, and the display brightness of the identification pattern gradually changes from bright to dim to full-dark, thereby presenting a layering sense and improving the visual experience of the user.
Of course, it is also possible to set the opening widths of the first opening 119 and the second opening 120 to be different, and the opening widths of the third opening 132 and the fourth opening 133 to be different. When the opening width that sets up light shield layer and polarisation layer sets up differently, can set up as required to show the different logo pattern of bright dark, the stereovision appears in the demonstration of logo pattern to promote user experience.
