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, and the display panel includes a display region 111. The PCBA is connected with the first substrate, is bent downwards and is attached to the lower surface of the first 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, the PCBA cannot be seen when a user watches a television from the upper surface of the substrate, only the front glass substrate can be seen, and 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, fig. 5, fig. 6 and fig. 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 a display panel, and fig. 7 is a schematic top view of a display panel corresponding to the identification device 133 corresponding to the non-display area 112. In an 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, the display panel 110 includes a first substrate 113, a second substrate 115 and a backlight module 116, the first substrate 113 and the second substrate 115 are disposed opposite to each other; the backlight module 116 is disposed on a side of the second substrate 115 away from the first substrate 113; the non-display area 112 of the display panel 110 is provided with an identification device 133, and the identification device 133 includes a hollow-out portion 121 formed on the first substrate 113 and/or the second substrate 115 corresponding to the non-display area 112; and an integrally formed color block 122 disposed corresponding to the hollow portion 121; the non-display area 112 is provided with a first polarizer 128 and a second polarizer 129 corresponding to the identification device 133, and the first polarizer 128 and the second polarizer 129 are provided corresponding to the hollow portion 121; at least one of the first polarizer 128 and the second polarizer 129 has an opening corresponding to the hollow portion 121.
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 is not favorable for realizing the frameless setting. In the scheme, the non-display area 112 of the display panel is provided with the identification device 133, and the hollow part 121 is arranged to correspond to the identification device 133, so that manufacturers do not need to additionally arrange a frame to place the identification device 133, and the design without the frame is realized; in addition, the marking device 133 includes the color resistance block 122 formed integrally and correspondingly disposed with the hollow portion 121, so that the marking patterns 134 can display the same or different colors without disposing a separate electrode layer and a separate control circuit, thereby improving the visual experience of the user. Since the transmittance of the polarizer to light is generally between 30% and 60%, and the opening is disposed at the position of the polarizer corresponding to the hollow portion 121, the transmittance of the light emitted by the light source is increased, so that the logo pattern 134 is brighter on the premise of the same backlight module 116, and thus the brighter logo pattern 134 can be displayed in the non-display area 112.
The liquid crystal layer 114 may not be disposed in the region corresponding to the non-display region 112, so that the amount of liquid crystal used may be reduced, thereby saving cost. Of course, it may be set as desired.
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 identification device 133 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 patterns 134 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 134 (e.g., letters or chinese characters), but may be disposed on at least two sides of the non-display area 112 respectively to form a complete Logo, which is beneficial to realizing a borderless design.
As shown in fig. 8, in an embodiment, the first substrate 113 is provided with a first light shielding layer 117 corresponding to the non-display region 112, the first polarizer 128 is located on a surface of the first light shielding layer 117 away from the second substrate 115, the second substrate 115 is provided with a second light shielding layer 118 corresponding to the non-display region 112, and the second polarizer 129 is located on a surface of the second light shielding layer 118 away from the first substrate 113; the first light shielding layer 117 and the second light shielding layer 118 are respectively provided with a first opening 119 and a second opening 120; the first opening 119 and the second opening 120 are correspondingly arranged to form the hollow-out part 121; only the first polarizer 128 of the first and second polarizers 128 and 129 is provided with a third opening 138 at a position corresponding to the first opening 119, and the identification device 133 at least comprises an identification pattern 134; the logo 134 is formed by the first opening 119, the second opening 120, the third opening 138 and the color block 122.
Only the first polarizer 128 of the corresponding first polarizer 128 and second polarizer 129 is provided with a third opening 138 at a position corresponding to the second opening 120, and the second polarizer 129 is not provided with an opening at a position corresponding to the second opening 120. The transmittance of one polarizer to light is generally between 30% and 60%, so that the light transmitted out from the backlight is not too bright or too dark, 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 133 is brighter.
Of course, it may also be arranged that only the second polarizer 129 of the first polarizer 128 and the second polarizer 129 is provided with a fourth opening 139 corresponding to the second opening 120, and the identification device 133 at least includes one identification pattern 134; the logo 134 is formed by the first opening 119, the second opening 120, the fourth opening 139 and the color block 122. Since the fourth opening 139 is close to the backlight module 116, the light emitted from the backlight module 116 is less lost in the process of propagation, so that the color of the identification pattern 134 can be more vividly displayed.
As shown in fig. 9, a third opening 138 is disposed at a position of the first polarizer 128 corresponding to the first opening 119, a fourth opening 139 is disposed at a position of the second polarizer 129 corresponding to the second opening 120, and the identification device 133 at least includes an identification pattern 134; the logo 134 is formed by the first opening 119, the second opening 120, the third opening 138, the fourth opening 139 and the color block 122. The third opening 138 and the fourth opening 139 are both opened, and since both polarizers are provided with openings, compared with a scheme in which only one opening is provided or no opening is provided, the transmittance of light is greatly improved, so that the whole logo 134 is more striking and bright.
Specifically, the orthographic projection of the shape of the overlapping area of the first opening 119 and the second opening 120 on the first substrate coincides with the orthographic projection of the identification pattern 134 on the first substrate; the color block 122 is in accordance with the shape of the logo 134, and the orthographic projection of the color block 122 on the first substrate covers the orthographic projection of the logo 134 on the first substrate.
The color block 122 should cover at least the overlapping area of the first opening 119 and the second opening 120, so that each place corresponding to the predetermined identification pattern 134 can display a color to uniformly control the brightness of each portion of the predetermined identification pattern 134.
For example, when the preset identification pattern 134 includes a character H, one color block 122 may be disposed corresponding to the left vertical edge of H, another color block 122 may be disposed corresponding to the right vertical edge, and another color block 122 may be disposed corresponding to the water balance edge; the color of the color block 122 may be the same or different; of course, other arrangements are possible, but here the width of the color-resist block 122 is much larger than the width of the color-resist of the display area.
The identification pattern 134 includes at least one identification sub-pattern 135, and the identification sub-pattern 135 may correspond to only one color block 122, or may correspond to the superposition of a plurality of color blocks 122 with different colors, so that different identification sub-patterns 135 may correspond to the same or different colors, so as to meet the needs of users for displaying different colors. The color block 122 may include a red color block, a green color block, or a blue color block, wherein the color block is set to be thin, for example, the red color block cannot completely block light of other colors, the green color block cannot completely block light of green colors, and the blue color block cannot completely block light of blue colors, so that the color mixture effect can be seen even if the three blocks are superposed.
The shape of the third opening 138 and/or the fourth opening 139 is consistent with the shape of the logo pattern 134, and the orthographic projection of the third opening 138 and/or the fourth opening 139 on the first substrate falls within the logo pattern 134. The orthographic projection of the third opening 138 and/or the fourth opening 139 on the first substrate is in the identification pattern 134, so that the light transmittance of the area where the third opening 138 and/or the fourth opening 139 is overlapped with the identification pattern 134 is larger, the brightness is brighter, the brightness of other areas where the third opening 138 and/or the fourth opening 139 is not overlapped is darker, and the brightness of the overall identification pattern 134 is different, so that a halo effect can be generated, and the visual experience of a user is improved.
When the first opening 119 is smaller than the second opening 120, 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, and the thickness of the first semi-transparent region is smaller than that of other regions in the first light shielding layer 117. Because the opening width of the first opening 119 is smaller than the opening width 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 position where the second opening 120 and the first light shielding layer 117 overlap, and the thickness of the first semi-transparent region where the first light shielding layer 117 is disposed is smaller than the thickness of other regions in the first light shielding layer 117, so that part of the light can penetrate through the first semi-transparent region, and the display brightness of the preset identification pattern 134 gradually changes from bright to dim to full-dark, thereby presenting a hierarchical sense and improving the visual experience of the user. Wherein, the opening size means that the shape and the size are the same, the edges of the openings are aligned, and all the edges are aligned in the vertical direction.
When the opening width of the first opening 119 is greater than the opening width of the second opening 120, a region of the second light shielding layer 118 where the first opening 119 and the second light shielding layer 118 overlap with each other is a second semi-transparent region, and the thickness of the second semi-transparent region is smaller than the thickness of other regions of 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 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, and the display brightness of the preset identification pattern 134 gradually changes from bright to dim to full-dark, thereby presenting a hierarchical sense and improving the visual experience of the user.
The identification pattern 134 comprises at least one identification sub-pattern 135; one of the identification sub-patterns 135 corresponds to one of the color block 122, the first opening 119 includes a plurality of first sub-openings 136, and the second opening 120 includes a plurality of second sub-openings 137; each identification sub-pattern 135 is correspondingly provided with a first sub-opening 136, a second sub-opening 137 and an integrally formed color resistance block 122; the colors between two adjacent color-resist blocks 122 are the same or different. The individual sub-patterns 135 are integrally formed, one sub-pattern 135 corresponds to one sub-opening and one color block 122, and the whole sub-pattern 135 can uniformly display the same color.
The display area includes a display color resist layer, and the display color resist layer and the color resist of the identification device 133 are formed through the same process. The color resistance layer of the display area and the color resistance of the marking device 133 are formed by the same process, thereby reducing the process time and improving the production efficiency.
