Description

display device

[0001] The present disclosure relates to a display device.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, various display devices such as LCD (Liquid Crystal Display Device), PDP (Plasma Display Panel), ELD (Electro luminescent Display), and VFD (Vacuum Fluorescent Display) are being researched and used in recent years.

[0003] Among these, the LCD panel has a TFT substrate and a color substrate that face each other with a liquid crystal layer between them, and can display images using light provided from a backlight unit.

[0004] Conventional backlight unit substrates (LED substrates) are attached to a frame using double-sided tape. However, this requires removing the release paper from the tape to attach the substrate to the frame, which presents a significant inconvenience and increases process costs. Furthermore, there is a risk of damage to the substrate during the process of detaching it from the frame. Furthermore, the adhesive strength of the double-sided tape decreases in high-temperature environments, causing the substrate to detach from the frame.

[0005] The present disclosure aims to solve the above-mentioned and other problems.

[0006] Another purpose may be to provide various structures for bonding the substrate to the frame.

[0007] Another purpose may be to provide a structure that minimizes lifting of the substrate relative to the frame.

[0008] Another purpose may be to provide a bracket having supports that not only bond the substrate to the frame, but also support the diffuser plate.

[0009] Another purpose may be to provide a structure that allows heat generated from the substrate to be easily transferred to the frame.

[0010] Another purpose may be to provide a back cover that covers part of the rear of the frame.

[0011] Another purpose may be to provide a bonding structure for the substrate to a frame that is only partially covered by the back cover.

[0012] According to one aspect of the present disclosure for achieving the above or other purposes, a display device may include: a display panel; a frame positioned at the rear of the display panel; a substrate positioned between the display panel and the frame; light sources mounted on the substrate and providing light to the display panel; and a bracket positioned between the substrate and the frame, the substrate being coupled thereto, and positioned on the frame, wherein the bracket may include: a protrusion protruding from one side of the bracket and detachably coupled to the frame.

[0016] According to at least one of the embodiments of the present disclosure, a bracket may be provided that not only couples a substrate to a frame but also has a supporter that supports a diffuser plate.

[0017] According to at least one of the embodiments of the present disclosure, a structure can be provided in which heat generated from a substrate can be easily transferred to a frame.

[0018] According to at least one of the embodiments of the present disclosure, a back cover covering a portion of the rear surface of the frame can be provided.

The diffusion sheet may prevent the light from the diffusion plate (129) from being partially concentrated, thereby making the distribution of the light more uniform. The number and / or positions of the prism sheets and the diffusion sheets may be changed.

[0057]

[0058] Referring to FIGS. 4 and 5, the substrate (122) may be elongated and may have a bar shape.

The bracket (201) may be coupled or attached to the rear of the substrate (122). The bracket (201) may include a metal material such as iron or stainless steel. The bracket (201) may be referred to as a plate (201), a bar (201), or a supporter (201).

[0079]

[0080] Referring to FIGS. 9 to 11, a user can insert an insertion portion (1221) of a substrate (122) into an insertion hole (134LH) while tilting the substrate (122), and the insertion portion (1221) can be caught on a catch portion (134L). When the user places the substrate (122) on the mounting portion (134) of the frame (130), the other end of the substrate (122) can be supported by a protrusion (134P) of the mounting portion (134). Here, the other end (e.g., a lower end) of the substrate (122) can be opposed to one end (e.g., an upper end) of the substrate (122) formed by the insertion portion (1211), and the protrusion (134P) can protrude from the front of the mounting portion (134).

[0081] The bracket (201) can be positioned on the mounting portion (134) while being coupled to the rear surface of the substrate (122). The bracket (201) can be magnetically coupled to magnets (134M) inserted into the grooves (134H) of the mounting portion (134).

[0082] Accordingly, the substrate (122) can be detachably coupled to the frame (130). A plurality of substrates (122, see FIG. 5) can be detachably coupled to the frame (130). The bracket (201) can be exposed rearward through the holes (130Ha, 130Hb), and in order to prevent foreign substances from entering the holes (130Ha, 130Hb), a member such as tape can be attached to the rear of the mounting portion (134) to block the holes (130Ha, 130Hb).

[0083] Meanwhile, the substrate (122) described above and below may be mounted and coupled on a flat portion of the frame (130), such as the central portion (131), instead of the mounting portion (134) of the frame (130).

The first recessed portion (2021) may be formed by pressing backward from the front surface of the body (2020) and may form a first side (S1, for example, a left side) of the body (2020). The second recessed portion (2022) may be formed by pressing backward from the front surface of the body (2020) and may form a second side (S2, for example, a right side) of the body (2020). The first and second recessed portions (2021, 2022) may form a step lowering backward from the body (2020).

[0090] The connecting portion (2023) may protrude from the body (2020) toward the substrate (122). The first connecting portion (2023a) may protrude from the third side (S3, for example, the upper side) of the body (2020) toward the substrate (122). The second connecting portion (2023b) may protrude from the fourth side (S4, for example, the lower side) of the body (2020) toward the substrate (122).

The second insertion hole (1342H) may be formed on the side of the second catch (1342). For example, the first and second catch portions (1341, 1342) may be formed by pressing from the rear side of the mounting portion (134) forward in a state where a portion of the mounting portion (134) is cut. In this case, holes (130Hc, 130Hd) can be formed in the mounting portion (134) of the frame (130) corresponding to the formation of the first and second catch portions (1341H, 1342H).

[0100] Meanwhile, the first and second recessed portions (2021, 2022) can be exposed to the rear through the holes (130Hc, 130Hd), and in order to prevent foreign substances from entering the holes (130Hc, 130Hd), a member such as tape can be attached to the rear of the mounting portion (134) to block the holes (130Hc, 130Hd).

[0101]

[0102] Referring to Fig. 17, the catch portion (1343) may protrude from the front of the mounting portion (134).

[0106] The guide pin (134N) can protrude from the front of the mounting portion (134) and can be inserted into the guide hole (122N) of the substrate (122). Each of the guide pin (134N) and the guide hole (122N) can be provided in multiple numbers. Accordingly, the guide pin (134N) can guide the coupling between the substrate (122) and the mounting portion (134).

[0107]

[0108] Referring to Fig. 20, the bending portion (1344) formed on the catch portion (1343) can press the front surface of the substrate (122). Accordingly, the bending portion (1344) can bring the substrate (122) into close contact with the mounting portion (134). The circuit pattern of the substrate (122) can be formed by avoiding the front surface of the substrate (122) that touches the bending portion (1344).

[0109] Meanwhile, the substrate (122) can be exposed to the rear through the hole (130He), and in order to prevent foreign substances from entering the hole (130He), a material such as tape can be attached to the rear of the mounting portion (134) to block the hole (130He).

The rotation of the bracket (203) can be restricted by the groove (2033) of the bracket (203) being caught by the body (203ba) of the catch pin (203b). At this time, the body (203ba) of the catch pin (203b) can be pressed into the groove (2033). Accordingly, the substrate (122) can be coupled to the mounting portion (134).
