Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display device. BACKGROUND

[0002] In order to improve the display area under the same display size, the bezel less design of liquid crystal display device has become an important trend of the development of current display technology. Compared with the structure of the traditional liquid crystal display device, the bezel less liquid crystal display device removes the front frame of the non-bonding side, so that the liquid crystal display panel is directly exposed to the outside, realizing the visual effect of whole surface integration. The side of the conventional bezel less liquid crystal display device is not shielded, which causes the backlight module of the liquid crystal display device to be easily projected from the edge of the liquid crystal display panel to the outside, resulting in the problem of obvious light leakage of the liquid crystal display device when viewed from the side. CONTENT OF THE UTILITY MODEL

[0003] Embodiments of the present application provide a display device to improve the problem of side view light leakage of the display device.

[0004] Embodiments of the present application provide a display device, comprising a display area and a non-display area surrounding the display area, the non-display area comprising a side frame area, the part of the display device located in the side frame area comprising:

[0005] a backlight module;

[0006] a middle frame, the middle frame being arranged on the backlight module;

[0007] a display panel, the display panel being arranged on the middle frame, the display panel comprising an array substrate and a counter substrate, the array substrate being arranged on the middle frame, the counter substrate being arranged on the side of the array substrate away from the backlight module, the distance from the edge of the array substrate to the display area being less than the distance from the edge of the counter substrate to the display area;

[0008] a sealing glue, the sealing glue covering part of the sidewall of the array substrate and part of the sidewall of the counter substrate;

[0009] a light shielding glue, the light shielding glue being arranged between the middle frame and the array substrate, part of the light shielding glue being beyond the edge of the array substrate, and part of the light shielding glue beyond the edge of the array substrate covering part of the sidewall of the array substrate.

[0010] Further, the first interval between the edge of the array substrate and the edge of the counter substrate is not greater than 1mm.

[0011] Furthermore, the display device also includes a first polarizer, which is disposed on a surface of the opposing substrate away from the backlight module, and the distance from the edge of the first polarizer to the display area is greater than the distance from the edge of the opposing substrate to the display area.

[0012] Furthermore, there is a second gap between the edge of the first polarizer and the edge of the opposing substrate, the second gap being no greater than 0.3 mm.

[0013] Furthermore, the light-shielding adhesive does not extend beyond the edge of the first polarizer.

[0014] Furthermore, the length of the light-shielding adhesive extending beyond the edge of the array substrate is no greater than 0.5 mm.

[0020] The beneficial effects of this application are:

[0021] This application provides a display device in which the distance from the edge of the array substrate to the display area is set to be less than the distance from the edge of the opposing substrate to the display area, thereby reducing the inward position of the array substrate relative to the opposing substrate. Then, a sealant is applied to cover the sidewall of the opposing substrate and a portion of the sidewall of the array substrate. A light-shielding adhesive is placed between the middle frame and the array substrate, with a portion of the light-shielding adhesive extending beyond the edge of the array substrate and covering a portion of the sidewall of the array substrate. This allows the light-shielding adhesive and sealant to block light from the edge of the display device, thereby improving the problem of light leakage when viewed from the side.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0027] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0028] Embodiments of this application provide a display device, with reference to... Figure 1 and Figure 2 The display device includes a display area AA and a non-display area NA surrounding the display area AA. The non-display area NA includes a side frame area NA1. The portion of the display device located within the side frame area includes a backlight module 100, a middle frame 200, a display panel 300, a sealant 400, and a light-shielding adhesive 500.

[0029] Specifically, the middle frame 200 is disposed on the backlight module 100; the display panel 300 is disposed on the middle frame 200, and the display panel 300 includes an array substrate 310 and an opposing substrate 320. The array substrate 310 is disposed on the middle frame 200, and the opposing substrate 320 is disposed on the side of the array substrate 310 away from the backlight module 100. The distance from the edge S1 of the array substrate 310 to the display area is less than the distance from the edge S2 of the opposing substrate 320 to the display area. The sealant 400 covers the sidewall of the opposing substrate 320 and a portion of the sidewall of the array substrate 310. The light-shielding adhesive 500 is disposed between the middle frame 200 and the array substrate 310. A portion of the light-shielding adhesive 500 extends beyond the edge S1 of the array substrate 310, and the portion of the light-shielding adhesive 500 extending beyond the edge S1 of the array substrate 310 covers a portion of the sidewall of the array substrate 310.

[0030] Conventional frameless LCD devices have no side shielding, causing the backlight module 100 to easily project light from the edge of the LCD panel 300 into the outside, resulting in noticeable light leakage when viewed from the side. Therefore, the technical solution of this application addresses this issue by setting the distance from the edge S1 of the array substrate 310 to the display area to be smaller than the distance from the edge S2 of the opposing substrate 320 to the display area, thus indenting the array substrate 310 relative to the opposing substrate 320. Then, the sealant 400 covers the sidewalls of the opposing substrate 320 and a portion of the sidewalls of the array substrate 310. The light-shielding adhesive 500 is placed between the middle frame 200 and the array substrate 310, with a portion of the light-shielding adhesive 500 extending beyond the edge S1 of the array substrate 310 and covering a portion of the sidewalls of the array substrate 310. This allows the light-shielding adhesive 500 and the sealant 400 to block light from the edge of the display device, thereby improving the light leakage problem when viewed from the side.

[0031] In this embodiment, the side bezel area NA1 refers to the top bezel area, left bezel area, and right bezel area outside the binding area of ​​the display device.

[0032] It should be noted that the binding area of ​​the display device is the lower border area of ​​the display device.

[0033] In this embodiment, the display device is a liquid crystal display device.

[0034] In this embodiment, reference Figure 2 The backlight module 100 also includes a back plate 110, which includes a bottom plate and a side plate, and the side plate is connected to the bottom plate to form a receiving cavity.

[0035] In this embodiment, reference Figure 2 The backlight module 100 also includes a light guide plate 120, which is disposed within the receiving cavity.

[0036] In this embodiment, reference Figure 2 The backlight module 100 further includes a reflective sheet 130, which is disposed on a surface of the light guide plate 120 away from the display panel 300.

[0037] In this embodiment, reference Figure 2 The backlight module 100 further includes an optical film 140, which is disposed on a surface of the light guide plate 120 near the display panel 300.

[0038] In this embodiment, reference Figure 2A first gap d1, not greater than 1 mm, exists between the edge S1 of the array substrate 310 and the edge S2 of the opposing substrate 320. Since the display device is a liquid crystal display device, a liquid crystal layer is also disposed between the array substrate 310 and the opposing substrate 320. The liquid crystal in the liquid crystal layer is located within the cavity of the frame adhesive at the edge S2 of the array substrate 310 and the opposing substrate 320. When the array substrate 310 is excessively recessed, it can easily affect the setting of the frame adhesive. Therefore, by setting a first gap d1, not greater than 1 mm, between the edge S1 of the array substrate 310 and the edge S2 of the opposing substrate 320, interference with the frame adhesive can be avoided. Preferably, the first spacing d1 is 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, 0.71mm, 0.72mm, 0.73mm, or 0.74mm. , 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm, 0.8mm, 0.81mm, 0.82mm, 0.83mm, 0.84mm, 0.85mm, 0.86mm, 0.87m m, 0.88mm, 0.89mm, 0.9mm, 0.91mm, 0.92mm, 0.93mm, 0.94mm, 0.95mm, 0.96mm, 0.97mm, 0.98mm, 0.99mm or 1mm.

[0039] In this embodiment, reference Figure 2 The display device further includes a first polarizer 600, which is disposed on a surface of the opposing substrate 320 away from the backlight module 100. The distance from the edge S3 of the first polarizer 600 to the display area is greater than the distance from the edge S2 of the opposing substrate 320 to the display area. By setting the first polarizer 600 to a surface of the opposing substrate 320 away from the backlight module 100, and the distance from the edge S3 of the first polarizer 600 to the display area being greater than the distance from the edge S2 of the opposing substrate 320 to the display area, the polarizer is extended outward compared to conventional solutions. During the manufacturing of the display device, on the one hand, it can prevent the sealant 400 from overflowing onto the surface of the polarizer away from the backlight module 100, thus avoiding affecting the display of the display device; on the other hand, it can ensure that the sealant 400 can better fill the corner area between the opposing substrate 320 and the first polarizer 600, thereby improving the sealing performance of the display device.

[0040] In this embodiment, reference Figure 2 A second distance d2 is provided between the edge S3 of the first polarizer 600 and the edge S2 of the opposing substrate 320, and the second distance d2 is not greater than 0.3 mm. By providing a second distance d2 between the edge S3 of the first polarizer 600 and the edge S2 of the opposing substrate 320, and the second distance d2 is not greater than 0.3 mm, the risk of warping of the edge S3 of the first polarizer 600 due to excessively long outward extension can be reduced. Preferably, the second distance d2 is 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, or 0.3 mm.

[0041] In this embodiment, reference Figure 2 The light-shielding adhesive 500 does not exceed the edge S3 of the first polarizer 600.

[0042] In this embodiment, reference Figure 2 The length of the light-shielding adhesive 500 extending beyond the edge S1 of the array substrate 310 is no greater than 0.5 mm. Preferably, the length of the light-shielding adhesive 500 extending beyond the edge S1 of the array substrate 310 is 0.3 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, or 0.5 mm.

[0043] In this embodiment, reference Figure 2The display device further includes a second polarizer 700, which is disposed on a surface of the array substrate 310 near the backlight module 100. In a top view of the display device, the second polarizer 700 does not overlap with the light-shielding adhesive 500. By including the second polarizer 700 on a surface of the array substrate 310 near the backlight module 100, and ensuring that the second polarizer 700 does not overlap with the light-shielding adhesive 500 in a top view (i.e., the bottom surface of the light-shielding adhesive 500 does not contact the bottom surface of the second polarizer 700), the adhesion effect of the light-shielding adhesive 500 can be prevented from weakening due to step differences when it is bonded to the surface of the array substrate 310 away from the opposing substrate 320.

[0044] In this embodiment, reference Figure 2 The distance from the edge S4 of the second polarizer 700 to the edge S1 of the array substrate 310 is greater than the distance from the edge S1 of the array substrate 310 to the edge S2 of the opposing substrate 320. By setting the distance from the edge S4 of the second polarizer 700 to the edge S1 of the array substrate 310 to be greater than the distance from the edge S1 of the array substrate 310 to the edge S2 of the opposing substrate 320, compared to a scheme where the distance from the edge S4 of the second polarizer 700 to the edge S1 of the array substrate 310 is not greater than the distance from the edge S1 of the array substrate 310 to the edge S2 of the opposing substrate 320, the array substrate 310 can have more space to accommodate the light-shielding adhesive 500, thereby reducing the difficulty of the display device manufacturing process.

[0045] In this embodiment, reference Figure 2 The sidewall of the array substrate 310 is perpendicular to the bottom wall of the opposing substrate 320. By setting the sidewall of the array substrate 310 to be perpendicular to the bottom wall of the opposing substrate 320, compared to the solution of tilting the sidewall of the array substrate 310 to the bottom wall of the opposing substrate 320, which requires an additional angled grinding process to grind the edge of the array substrate 310, one C-angle angled grinding process can be saved, thereby simplifying the manufacturing process of the display device.

[0046] In this embodiment, the material of the light-shielding adhesive 500 is a black semi-solid adhesive. By setting the material of the light-shielding adhesive 500 to a black semi-solid adhesive, on the one hand, the black color of the semi-solid adhesive can more effectively block light, and on the other hand, the black semi-solid adhesive can more easily cover the sidewalls of the array substrate 310, thereby ensuring that the problem of light leakage when viewed from the side of the display device can be effectively improved.

[0047] In this embodiment, the material of the light-shielding adhesive 500 is black foam adhesive. By setting the material of the light-shielding adhesive 500 to black foam adhesive, the black color of the foam adhesive can more effectively block light, thereby effectively improving the problem of light leakage when viewing the display device from the side.

[0048] The specific embodiments of this application have been described in detail above. The embodiments disclosed above are merely preferred embodiments of this application. Those skilled in the art can make many modifications and improvements without departing from the concept of this application. All such modifications and improvements fall within the scope of protection defined by the claims of this application.
