Description

Technical Field

[0001] The present disclosure relates to the technical field of display screens, and in particular to a novel display module and a display screen. Background Art

[0002] As aesthetic trends evolve, the demand for display screen bezels is trending towards narrower borders. Advanced displays employ a solution that attaches a sheet of glass to the base structure of the display module as the outermost layer. A circle of black ink is applied around the edge of the outer glass to conceal the black tape surrounding the display module, allowing the display module to achieve an edge-to-edge appearance across the entire system. This solution not only eliminates the thin bezel to achieve an extremely narrow border design, but also makes the display module more aesthetically pleasing and stylish.

[0003] However, this solution also has certain drawbacks. For example, the display module is composed of two pieces of glass: the color filter layer on the top and the thin-film transistor layer on the bottom. The printed circuit board is electrically connected to the thin-film transistor layer via an integrated circuit. This solution adds an extra piece of glass to the display module, bringing the total to three pieces. This increases the overall thickness of the display module and prevents it from achieving thinness and lightness. Furthermore, the additional outermost glass requires a lamination process, which increases manufacturing costs.

[0004] In view of this, the market is in urgent need of a display module with a new structure to achieve an extremely narrow frame design of the display module while also meeting the requirements of a thin and lightweight display module and low cost. Summary of the Invention

[0018] The lower long side of the thin film transistor glass layer protrudes from the lower long side of the color filter glass layer and forms the protruding portion for mounting the integrated circuit.

[0019] In one embodiment, a plastic frame is at least partially provided on the edge of the color filter glass layer facing away from the display side;

[0020] The outer edge of the first polarizer is flush with the outer edge of the plastic frame.

DETAILED DESCRIPTION

[0043] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0044] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0045] Combine Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a new display module, which includes a first polarizer 1, a thin-film transistor glass layer 2, a color filter glass layer 3 and a second polarizer 4 stacked in sequence; the side of the first polarizer 1 facing away from the second polarizer 4 is a display side; the side of the second polarizer 4 facing away from the first polarizer 1 is a backlight side; a light-shielding interlayer 5 is provided between the edge of the thin-film transistor glass layer 2 facing the first polarizer 1 and the first polarizer 1; the outer edge of the first polarizer 1 is arranged flush with the outer edge of the light-shielding interlayer 5; wherein the thin-film transistor glass layer 2 has a protruding portion 21 that protrudes beyond the color filter glass layer 3, and an integrated circuit 211 electrically connected to a circuit board is provided in the protruding portion 21.

[0046] The novel display module provided by the embodiments of the present disclosure can be specifically but not limited to being applied to a liquid crystal display screen in a computer, and this will be specifically described as an example.

[0047] Unlike conventional LCD displays, in which the color filter glass layer is disposed in front of the thin-film transistor glass layer 2 (the front specifically refers to the end closest to the display side), conventional LCD displays require the integrated circuit to be disposed above the thin-film transistor glass layer, and the color filter glass layer needs to avoid the integrated circuit. As a result, the bottom side of the LCD display and the other three sides (left side, right side, and top side) cannot form a single flat surface.

[0048] Further integration Figure 3 and Figure 4 As shown, compared with a conventional LCD display screen, the novel display module provided by the embodiment of the present disclosure, on the contrary, arranges the thin-film transistor glass layer 2 in front of the color filter glass layer 3 (the front specifically refers to the end close to the display side). This is to enable the integrated circuit 211 to be arranged below the thin-film transistor glass layer 2, adopting a "hidden under layer" arrangement. In this way, the thin-film transistor glass layer can be arranged with the same length and width as the first polarizer 1 on all four sides, so that the four sides (left side, right side, top side and bottom side) of the novel display module can form a single flat surface.

[0049] In addition, since a light-shielding interlayer 5 is provided between the edge of the thin-film transistor glass layer 2 facing the first polarizer 1 and the first polarizer 1, the light-shielding interlayer 5 can be specifically but not limited to a black photoresist material, which is used to block light leakage from the edge of the new display module, so that a rectangular "ultra-narrow frame" visual effect can be formed around the new display module.

[0050] Furthermore, the outer edge of the first polarizer 1 is flush with the outer edge of the light-shielding interlayer 5, making the layer closest to the display side of the new display module a single, integrated, flat surface when viewed from the front. This maximizes the ratio of the visible area to the system's external appearance area, creating the illusion of a single piece of glass, and achieving an edge-to-edge visual effect for the entire display. This eliminates the need for a glass layer, resulting in a lighter and thinner display module. It also eliminates the need for a glass layer, reducing manufacturing costs.

[0051] To sum up, the new display module provided by the embodiment of the present disclosure, while realizing the function of extremely narrow bezels on all sides, can also make the outermost layer of the new display module close to the display side an integrated whole surface, so as to maximize the visible area of ​​the new display module, and the outermost first polarizer 1 visually looks like an "external glass layer", realizing the "edge-to-edge" visual effect of the entire display machine, thereby reducing the use of one glass layer, making the thickness of the new display module lighter and thinner, and also saving the process of external glass layer. It has the beneficial effects of being able to achieve extremely narrow bezels on all sides, being light and thin in thickness, and having low production costs.

[0052] In one embodiment, a light-shielding cladding 6 is at least partially provided in the peripheral walls of the thin-film transistor glass layer 2 and the color filter glass layer 3 ; and the outer edge of the first polarizer 1 is flush with the outer edge of the light-shielding cladding 6 .

[0053] Specific, combined Figure 1 and Figure 3 To further explain in detail, a light-shielding cladding layer 6 is at least partially provided on multiple peripheral walls of the thin-film transistor glass layer 2 and the color filter glass layer 3. The light-shielding cladding layer 6 can be integrally formed and connected with the light-shielding interlayer 5 using the same black photoresist material. The light-shielding cladding layer 6 can further block light leakage from the edges of the new display module while also forming a "wrapped black border" on the three peripheral sides of the new display module, thereby further improving the visual appearance of the new display module.

[0054] In one embodiment, the thin film transistor glass layer 2 and the color filter glass layer 3 respectively have two long sides and two wide sides; the light shielding layer 6 is wrapped around the two wide sides and one long side.

[0055] Specific, combined Figure 1 and Figure 3 To further explain in detail, a light-shielding cladding layer 6 can be provided on the upper side, left side, and right side of the thin-film transistor glass layer 2 and the color filter glass layer 3, respectively. The light-shielding cladding layer 6 can be integrally formed and connected with the light-shielding interlayer 5 using the same black photoresist material. Since the lower side of the thin-film transistor glass layer 2 has a protruding portion 21 protruding from the lower side of the color filter glass layer 3, the lower sides of the two are not flush, and a light-shielding cladding layer 6 is no longer provided.

[0056] The specific configuration of the light-shielding layer 6 not only realizes the "black border" wrapping of the three peripheral sides of the new display module, but also does not affect the normal configuration and connection of the integrated circuit 211 on the lower side of the new display module.

[0057] In one embodiment, the two long sides of the thin-film transistor glass layer 2 and the color filter glass layer 3 are respectively an upper long side and a lower long side; the upper long side of the thin-film transistor glass layer 2 is flush with the upper long side of the color filter glass layer 3; the lower long side of the thin-film transistor glass layer 2 protrudes from the lower long side of the color filter glass layer 3 and forms a protruding portion 21 for mounting the integrated circuit 211.

[0058] Specific, combined Figure 4 To further explain in detail, the upper long side of the thin-film transistor glass layer 2 is flush with the upper side of the color filter glass layer 3, and the lower long side of the ice ball protrudes downward to form a protruding portion 21; the integrated circuit 211 is installed on the side of the protruding portion 21 that is opposite to the first polarizer 1, and can be electrically connected to the main circuit board 81 through a flexible printed circuit board (FPC).

[0059] The specific configuration of the protruding portion 21 can, on the one hand, place the integrated circuit 211 underneath, shorten the connection distance between the integrated circuit 211 and the motherboard, and reduce signal attenuation; on the other hand, the suspended design of the protruding portion 21 also increases the heat dissipation area and improves the heat dissipation efficiency of the new display module.

[0060] In one embodiment, a plastic frame 41 is at least partially provided on the edge of the color filter glass layer 3 facing away from the display side; and the outer edge of the first polarizer 1 is flush with the outer edge of the plastic frame 41 .

[0061] Specific, combined Figure 1 and Figure 2 To further explain in detail, the plastic frame 41 can be specifically but not limited to epoxy resin material, the frame wall cross-section of the plastic frame 41 can be set to an L-shaped corner, and is set at the edge of the color filter glass layer 3 facing away from the display side, and its outer edge is flush with the first polarizer 1.

[0062] The specific configuration of the above-mentioned glue frame 41 can stably bond and fix each layer structure while protecting the edge of the glass layer. In addition, the glue frame 41 can also make the color filter glass layer 3 and the first polarizer 1 flush and maintain the same width, thereby improving the overall structural stability of the new display module.

[0063] In one embodiment, the second polarizer 4 is located in the plastic frame 41 and has an outer peripheral wall spaced apart from and opposite to the plastic frame 41 .

[0064] Specific, combined Figure 1 and Figure 2To further explain in detail, the second polarizer 4 can be specifically but not limited to being embedded in the plastic frame 41, and the outer wall of the second polarizer 4 and the inner wall of the plastic frame 41 can be set to be 0.5mm to 1.0mm apart to avoid direct contact, provide a thermal expansion buffer space, and prevent the second polarizer 4 from deforming and warping due to temperature changes.

[0065] The specific arrangement of the second polarizer 4 can not only achieve barrier, wrapping and protection of the second polarizer 4 through the plastic frame 41 , but also prevent the optical performance of the second polarizer 4 from being deteriorated due to thermal expansion and compression of the plastic frame 41 .

[0066] In one embodiment, the new display module also includes a back panel component 7; the back panel component 7 is bonded to the side of the plastic frame 41 facing away from the second polarizer 4, and can form a back panel cavity 71 together with the color filter glass layer 3. The second polarizer 4 is located in the back panel cavity 71.

[0067] Specific, combined Figure 1 and Figure 2 To further explain in detail, the back panel 7 can be, but is not limited to, an aluminum back panel to quickly dissipate the heat of the new display module, and is bonded and fixed by a glue frame 41, and the back panel 7 and the color filter glass layer 3 together form a back panel cavity 71.

[0068] The back panel 7 can effectively block the light source from penetrating the backlight side. On the other hand, the back panel 7 can also be used to improve the heat dissipation efficiency of the new display module.

[0069] In one embodiment, the back plate 7 further includes a contact portion 72 ; the contact portion 72 directly contacts the side of the color filter glass layer 3 facing away from the display side.

[0070] Specific, combined Figure 4 To further explain in detail, the abutment portion 72 can be specifically formed by bending the lower side of the back panel 7 180 degrees toward the color filter glass layer 3. In this way, the back panel 7 can abut and distribute the load on the lower side of the color filter glass layer 3 through the abutment portion 72, thereby making the structure of the lower side of the color filter glass layer stronger, balancing the force on the color filter glass layer 3, and preventing local stress concentration on the lower side.

[0071] In one embodiment, the novel display module further includes a backlight module 8 ; the backlight module 8 is disposed on the backlight side of the second polarizer 4 .

[0072] Specific, combined Figure 4To further explain in detail, the backlight module 8 can be specifically but not limited to being configured as an LED light strip and a light guide plate, and both are respectively arranged on the backlight side of the second polarizer 4; in this way, the light emitted by the LED is evenly diffused by the light guide plate, and then passes through the second polarizer 4, the color filter glass layer 3 and the thin-film transistor glass layer 2 in sequence, and finally outputs the image by the first polarizer 1.

[0073] The specific configuration of the backlight module 8 described above effectively reduces light loss and improves imaging quality.

[0074] In addition, the embodiment of the present disclosure also provides a display screen, which includes a display; the display includes a circuit board 81 and the above-mentioned new display module; wherein the circuit board 81 is electrically connected to the integrated circuit 211 in the thin film transistor glass layer 2 through a conductive soft board.

[0075] The display screen can be specifically but not limited to a display screen in a computer. Since the display screen includes the above-mentioned new display module, it can achieve all the beneficial effects of the above-mentioned new display module, which will not be further elaborated here.

[0076] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0077] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
