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 first 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, the PCBA cannot be seen when a user watches a television from the upper surface of the substrate, 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 icon pattern or a brand), so a border exists on 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 non-display area 112 of a display panel. The application discloses a display device 100, the 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, a liquid crystal layer 114 and a backlight module 116, the first substrate 113 and the second substrate 115 are disposed on opposite sides, the liquid crystal layer 114 is disposed on one side of the second substrate 115 far away from the first substrate 113, the non-display area 112 of the display panel 110 is provided with an icon device 133, and the icon device 133 includes a hollow portion 121 formed on the first substrate 113 and/or the second substrate 115 corresponding to the non-display area 112, and a filter portion 122 disposed 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 bezel is also needed to set the Logo, which is not favorable for realizing a frameless design. In the scheme, the non-display area 112 of the display panel is provided with the icon device 133, and the hollow part 121 is arranged to correspond to the icon device 133, so that manufacturers do not need to additionally arrange a frame for placing the icon pattern 134, and the design without the frame is realized; in addition, the icon device 133 includes the integrally formed filtering portion 122 corresponding to the hollow portion 121, so that the icon patterns 134 can display the same or different colors without providing a separate electrode layer and a separate control circuit, thereby improving the visual experience of the user. The optical filter part can be an integrally formed color resist or a plurality of aligned color resists.
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 icon device 133133 may be disposed on any one side of the non-display area 112, for example, on the first long side 126, and optionally, 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, it is also possible that the icon device 133 is not disposed in the middle area of the first long side 126, and may also be disposed in the short side, and even the Logo includes a plurality of icon patterns 134 (e.g., letters or chinese characters), but it is also possible that the icon devices are respectively disposed on at least two sides of the non-display area 112 to form a complete Logo, which is beneficial to realizing a borderless design.
As shown in fig. 8, where W is the width direction of the sectional view. 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 light-shielding layer 117 is provided with a first opening 119 corresponding to the light-filtering portion 122 to form the hollow portion 121; the second substrate 115 corresponds to the first opening 119 to form the optical filter 122, and the icon device 133 at least includes an icon pattern 134; the first opening 119 and the optical filter portion 122 form the icon pattern 134.
The icon pattern 134 is a brand pattern or a trademark of a manufacturer, such as a letter or a Chinese character, and the present embodiment is only provided with a light shielding layer and a first opening 119 correspondingly disposed on the first light shielding layer 117, the first opening 119 is a light-permeable area, and the first opening 119 is disposed corresponding to the light-filtering portion 122, so that the shape and size of the first opening 119 are set corresponding to the predetermined icon pattern 134, and when the backlight module 116 is turned on, the predetermined icon pattern 134 is displayed. When the backlight module is opened, the backlight source only penetrates through the first opening of the light shielding layer, and the display brightness of the final icon device is brighter due to less loss in the light transmission process and higher light transmittance. Of course, the light-shielding layer may be provided in plural layers instead of only one layer, or may be provided in plural layers for better light shielding. The second substrate may be provided with a light-shielding layer, or the light-filtering portion may be provided directly on the glass substrate without providing the light-shielding layer.
Specifically, the second substrate 115 is provided with a second light shielding layer 118 corresponding to the non-display region 112; the second light shielding layer 118 is provided with a second opening 120 corresponding to the first opening 119; the optical filter part 122 is disposed in the second opening 120, and the first opening 119 and the second opening 120 are correspondingly disposed to form the hollow-out part 121; the first opening 119, the second opening 120 and the optical filter portion 122 together form the icon pattern 134. The size of the openings means that the shape area is the same, the edges of the openings are aligned, and the sides are aligned in the vertical direction.
When two light shielding layers are provided, the predetermined icon patterns 134 of the icon device 133 may be formed on the first light shielding layer 117 and/or the second light shielding layer 118. For example, if the predetermined icon pattern 134 corresponds to the shape of the first opening 119 of the first light shielding layer 117, the second light shielding layer 118 is also provided with a light transmitting region, i.e., the second opening 120, corresponding to the first opening 119, and the second opening 120 of the second light shielding layer 118 may be larger than the size of the first opening 119 of the first light shielding layer 117, so that when the backlight module 116 is turned on, the light transmitted through the second opening 120 of the second light shielding layer 118 can completely display the shape of the character or the pattern forming the first opening 119, and the shape of the second opening 120 does not need to completely correspond to the shape position of the first opening 119, which is low in requirement for processing precision and beneficial to improving production efficiency. Of course, the predetermined icon pattern 134 may also be configured to correspond to the shape of the second opening 120, and the width of the first opening 119 of the first light-shielding layer 117 may be greater than or equal to the width of the second opening 120 of the second light-shielding layer 118; of course, the shapes of the light-transmitting areas corresponding to the two light-shielding layers can also be set to correspond to the shapes of the preset icon patterns 134; as long as the overlapping area of the light-transmitting areas corresponding to the two light-shielding layers corresponds to the shape of the predetermined icon pattern 134.
Specifically, the shape of the first opening 119 corresponds to the shape of the icon pattern 134, and the width of the second opening 120 is greater than or equal to the width of the first opening 119; the width of the optical filter part 122 is greater than or equal to the width of the first opening 119, and the first opening 119, the second opening 120 and the optical filter part 122 form the icon pattern 134 with a preset shape and width.
The shape of the overlapping area of the first opening 119 and the second opening 120 is identical to the shape and width of the preset icon pattern 134; the covering position of the optical filter 122 represents the size of the color controllable portion of the preset icon pattern 134, and optionally, the shape and width of the optical filter 122 may be greater than or equal to the overlapping area of the first light-transmitting area and the second light-transmitting area, so that the color controllable portion of the preset icon pattern 134 may control the color display; of course, the area of the optical filter portion 122 may be smaller than the area of the overlapping area, and the color display may not be realized at a position where the optical filter portion 122 is not provided.
Of course, the shape of the second opening 120 may correspond to the shape of the icon pattern 134, the width of the first opening 119 may be greater than or equal to the width of the second opening 120, and the width of the optical filter 122 may be greater than or equal to the width of the first opening 119; the first opening 119, the second opening 120 and the filter 122 form the icon pattern 134 having a predetermined shape and size.
The shape of the overlapping area of the first and second openings 119 and 120 corresponds to the shape of the icon pattern 134; the width of the optical filter part 122 is smaller than that of the icon pattern 134, and the icon pattern 134 is formed in a predetermined shape and size by the first opening 119, the second opening 120, and the optical filter part 122. The coverage of the filter portion 122 should at least cover the overlapping area of the first opening 119 and the second opening 120, so that each place corresponding to the predetermined icon pattern 134 can display a color to uniformly control the brightness of each portion of the predetermined icon pattern 134.
For example, when the predetermined identification pattern includes a character H, one filter portion 122 may be disposed corresponding to a left vertical edge of the character H, another filter portion 122 may be disposed corresponding to a right vertical edge, and another filter portion 122 may be disposed corresponding to a water balance edge; the color of the filter portion 122 may be the same or different; of course, other arrangements are possible, but the size of the filter 122 here is much larger than the size of the color resistance of the display area.
The icon pattern 134 includes at least one icon sub-pattern 135, and the icon sub-pattern 135 may correspond to only one filter portion 122, or may correspond to the superposition of a plurality of filter portions 122 with different colors, so that different icon sub-patterns 135 may correspond to the same or different colors, so as to meet the user's requirements for displaying different colors.
